Before attending the Vienna Institute of Technology, Steiner had studied Kant, Fichte and Schelling. CANNOTANSWER
one of Steiner's teachers, Karl Julius Schroer, suggested Steiner's name to Joseph Kurschner,
Rudolf Joseph Lorenz Steiner (27 or 25 February 1861 – 30 March 1925) was an Austrian occultist, philosopher, social reformer, architect, esotericist, and claimed clairvoyant. Steiner gained initial recognition at the end of the nineteenth century as a literary critic and published philosophical works including The Philosophy of Freedom. At the beginning of the twentieth century he founded an esoteric spiritual movement, anthroposophy, with roots in German idealist philosophy and theosophy. His ideas are largely pseudoscientific. He was also prone to pseudohistory.

In the first, more philosophically oriented phase of this movement, Steiner attempted to find a synthesis between science and spirituality. His philosophical work of these years, which he termed "spiritual science", sought to apply what he saw as the clarity of thinking characteristic of Western philosophy to spiritual questions, differentiating this approach from what he considered to be vaguer approaches to mysticism. In a second phase, beginning around 1907, he began working collaboratively in a variety of artistic media, including drama, dance and architecture, culminating in the building of the Goetheanum, a cultural centre to house all the arts. In the third phase of his work, beginning after World War I, Steiner worked on various ostensibly applied  projects, including Waldorf education, biodynamic agriculture, and anthroposophical medicine.

Steiner advocated a form of ethical individualism, to which he later brought a more explicitly spiritual approach. He based his epistemology on Johann Wolfgang Goethe's world view, in which "thinking…is no more and no less an organ of perception than the eye or ear. Just as the eye perceives colours and the ear sounds, so thinking perceives ideas." A consistent thread that runs through his work is the goal of demonstrating that there are limits to human knowledge.

Biography

Childhood and education 

Steiner's father, Johann(es) Steiner (1829–1910), left a position as a gamekeeper in the service of Count Hoyos in Geras, northeast Lower Austria to marry one of the Hoyos family's housemaids, Franziska Blie (1834 Horn – 1918, Horn), a marriage for which the Count had refused his permission. Johann became a telegraph operator on the Southern Austrian Railway, and at the time of Rudolf's birth was stationed in Murakirály (Kraljevec) in the Muraköz region of the Kingdom of Hungary, Austrian Empire (present-day Donji Kraljevec in the Međimurje region of northernmost Croatia). In the first two years of Rudolf's life, the family moved twice, first to Mödling, near Vienna, and then, through the promotion of his father to stationmaster, to Pottschach, located in the foothills of the eastern Austrian Alps in Lower Austria.

Steiner entered the village school, but following a disagreement between his father and the schoolmaster, he was briefly educated at home. In 1869, when Steiner was eight years old, the family moved to the village of Neudörfl and in October 1872 Steiner proceeded from the village school there to the realschule in Wiener Neustadt.

In 1879, the family moved to Inzersdorf to enable Steiner to attend the Vienna Institute of Technology, where he enrolled in courses in mathematics, physics, chemistry, botany, zoology, and mineralogy and audited courses in literature and philosophy, on an academic scholarship from 1879 to 1883, where he completed his studies and the requirements of the Ghega scholarship satisfactorily. In 1882, one of Steiner's teachers, Karl Julius Schröer, suggested Steiner's name to Joseph Kürschner, chief editor of a new edition of Goethe's works,  who asked Steiner to become the edition's natural science editor, a truly astonishing opportunity for a young student without any form of academic credentials or previous publications.

Before attending the Vienna Institute of Technology, Steiner had studied Kant, Fichte and Schelling.

Early spiritual experiences 

When he was nine years old, Steiner believed that he saw the spirit of an aunt who had died in a far-off town, asking him to help her at a time when neither he nor his family knew of the woman's death. Steiner later related that as a child, he felt "that one must carry the knowledge of the spiritual world within oneself after the fashion of geometry ... [for here] one is permitted to know something which the mind alone, through its own power, experiences. In this feeling I found the justification for the spiritual world that I experienced ... I confirmed for myself by means of geometry the feeling that I must speak of a world 'which is not seen'."

Steiner believed that at the age of 15 he had gained a complete understanding of the concept of time, which he considered to be the precondition of spiritual clairvoyance. At 21, on the train between his home village and Vienna, Steiner met an herb gatherer, Felix Kogutzki, who spoke about the spiritual world "as one who had his own experience therein".

Writer and philosopher 
In 1888, as a result of his work for the Kürschner edition of Goethe's works, Steiner was invited to work as an editor at the Goethe archives in Weimar. Steiner remained with the archive until 1896. As well as the introductions for and commentaries to four volumes of Goethe's scientific writings, Steiner wrote two books about Goethe's philosophy: The Theory of Knowledge Implicit in Goethe's World-Conception (1886), which Steiner regarded as the epistemological foundation and justification for his later work, and Goethe's Conception of the World (1897). During this time he also collaborated in complete editions of the works of Arthur Schopenhauer and the writer Jean Paul and wrote numerous articles for various journals.

In 1891, Steiner received a doctorate in philosophy at the University of Rostock, for his dissertation discussing 
Fichte's concept of the ego, submitted to Heinrich von Stein, whose Seven Books of Platonism Steiner esteemed. Steiner's dissertation was later published in expanded form as Truth and Knowledge: Prelude to a Philosophy of Freedom, with a dedication to Eduard von Hartmann. Two years later, in 1894, he published Die Philosophie der Freiheit (The Philosophy of Freedom or The Philosophy of Spiritual Activity, the latter being Steiner's preferred English title), an exploration of epistemology and ethics that suggested a way for humans to become spiritually free beings. Steiner later spoke of this book as containing implicitly, in philosophical form, the entire content of what he later developed explicitly as anthroposophy.

In 1896, Steiner declined an offer from Elisabeth Förster-Nietzsche to help organize the Nietzsche archive in Naumburg. Her brother, Friedrich Nietzsche, was by that time non compos mentis. Förster-Nietzsche introduced Steiner into the presence of the catatonic philosopher; Steiner, deeply moved, subsequently wrote the book Friedrich Nietzsche, Fighter for Freedom. Steiner later related that:

My first acquaintance with Nietzsche's writings belongs to the year 1889. Previous to that I had never read a line of his. Upon the substance of my ideas as these find expression in The Philosophy of Spiritual Activity, Nietzsche's thought had not the least influence....Nietzsche's ideas of the 'eternal recurrence' and of 'Übermensch' remained long in my mind. For in these was reflected that which a personality must feel concerning the evolution and essential being of humanity when this personality is kept back from grasping the spiritual world by the restricted thought in the philosophy of nature characterizing the end of the 19th century....What attracted me particularly was that one could read Nietzsche without coming upon anything which strove to make the reader a 'dependent' of Nietzsche's.

In 1897, Steiner left the Weimar archives and moved to Berlin. He became part owner of, chief editor of, and an active contributor to the literary journal Magazin für Literatur, where he hoped to find a readership sympathetic to his philosophy. Many subscribers were alienated by Steiner's unpopular support of Émile Zola in the Dreyfus Affair and the journal lost more subscribers when Steiner published extracts from his correspondence with anarchist John Henry Mackay. Dissatisfaction with his editorial style eventually led to his departure from the magazine. In 1899, Steiner married Anna Eunicke; the couple separated several years later. Anna died in 1911.

Theosophical Society 

In 1899, Steiner published an article, "Goethe's Secret Revelation", discussing the esoteric nature of Goethe's fairy tale The Green Snake and the Beautiful Lily. This article led to an invitation by the Count and Countess Brockdorff to speak to a gathering of Theosophists on the subject of Nietzsche. Steiner continued speaking regularly to the members of the Theosophical Society, becoming the head of its newly constituted German section in 1902 without ever formally joining the society. It was also in connection with this society that Steiner met and worked with Marie von Sivers, who became his second wife in 1914. By 1904, Steiner was appointed by Annie Besant to be leader of the Theosophical Esoteric Society for Germany and Austria. In 1904, Eliza, the wife of Helmuth von Moltke the Younger, became one of his favourite scholars.<ref>{{cite book|last1=Meyer| first1= Thomas|title= Helmuth von Moltke, Light for the new millennium: Rudolf Steiner's association with Helmuth and Eliza von Moltke: letters, documents and after-death communications|publisher= Rudolf Steiner Press|place= London|year= 1997|isbn= 1-85584-051-0|language= en}}</ref> Through Eliza, Steiner met Helmuth, who served as the Chief of the German General Staff from 1906 to 1914.

In contrast to mainstream Theosophy, Steiner sought to build a Western approach to spirituality based on the philosophical and mystical traditions of European culture. The German Section of the Theosophical Society grew rapidly under Steiner's leadership as he lectured throughout much of Europe on his spiritual science. During this period, Steiner maintained an original approach, replacing Madame Blavatsky's terminology with his own, and basing his spiritual research and teachings upon the Western esoteric and philosophical tradition. This and other differences, in particular Steiner's vocal rejection of Leadbeater and Besant's claim that Jiddu Krishnamurti was the vehicle of a new Maitreya, or world teacher, led to a formal split in 1912–13, when Steiner and the majority of members of the German section of the Theosophical Society broke off to form a new group, the Anthroposophical Society. Steiner took the name "Anthroposophy" from the title of a work of the Austrian philosopher Robert von Zimmermann, published in Vienna in 1856. Despite his departure from the Theosophical Society, Steiner maintained his interest in Theosophy throughout his life.

 Anthroposophical Society and its cultural activities 
The Anthroposophical Society grew rapidly. Fueled by a need to find an artistic home for their yearly conferences, which included performances of plays written by Edouard Schuré and Steiner, the decision was made to build a theater and organizational center. In 1913, construction began on the first Goetheanum building, in Dornach, Switzerland. The building, designed by Steiner, was built to a significant part by volunteers who offered craftsmanship or simply a will to learn new skills. Once World War I started in 1914, the Goetheanum volunteers could hear the sound of cannon fire beyond the Swiss border, but despite the war, people from all over Europe worked peaceably side by side on the building's construction. Steiner moved from Berlin to Dornach in 1913 and lived there to the end of his life.

Steiner's lecture activity expanded enormously with the end of the war. Most importantly, from 1919 on Steiner began to work with other members of the society to found numerous practical institutions and activities, including the first Waldorf school, founded that year in Stuttgart, Germany. At the same time, the Goetheanum developed as a wide-ranging cultural centre. On New Year's Eve, 1922–1923, the building burned to the ground; contemporary police reports indicate arson as the probable cause. Steiner immediately began work designing a second Goetheanum building - this time made of concrete instead of wood - which was completed in 1928, three years after his death.

At a "Foundation Meeting" for members held at the Dornach center during Christmas, 1923, Steiner spoke of laying a new Foundation Stone for the society in the hearts of his listeners. At the meeting, a new "General Anthroposophical Society" was established with a new executive board. At this meeting, Steiner also founded a School of Spiritual Science, intended as an "organ of initiative" for research and study and as "the 'soul' of the Anthroposophical Society". This school, which was led by Steiner, initially had sections for general anthroposophy, education, medicine, performing arts (eurythmy, speech, drama and music), the literary arts and humanities, mathematics, astronomy, science, and visual arts. Later sections were added for the social sciences, youth and agriculture.Rudolf Steiner, Constitution of the School of Spiritual Science: Its arrangement in Sections 1964  The School of Spiritual Science included meditative exercises given by Steiner.

 Political engagement and social agenda 
Steiner became a well-known and controversial public figure during and after World War I. In response to the catastrophic situation in post-war Germany, he proposed extensive social reforms through the establishment of a Threefold Social Order in which the cultural, political and economic realms would be largely independent. Steiner argued that a fusion of the three realms had created the inflexibility that had led to catastrophes such as World War I. In connection with this, he promoted a radical solution in the disputed area of Upper Silesia, claimed by both Poland and Germany. His suggestion that this area be granted at least provisional independence led to his being publicly accused of being a traitor to Germany.

Steiner opposed Wilson's proposal to create new European nations based around ethnic groups, which he saw as opening the door to rampant nationalism. Steiner proposed, as an alternative:

 Attacks, illness, and death 
The National Socialist German Workers Party gained strength in Germany after the First World War. In 1919, a political theorist of this movement, Dietrich Eckart, attacked Steiner and suggested that he was a Jew. In 1921, Adolf Hitler attacked Steiner on many fronts, including accusations that he was a tool of the Jews, while other nationalist extremists in Germany called for a "war against Steiner". That same year, Steiner warned against the disastrous effects it would have for Central Europe if the National Socialists came to power. In 1922 a lecture Steiner was giving in Munich was disrupted when stink bombs were let off and the lights switched out, while people rushed the stage apparently attempting to attack Steiner, who exited safely through a back door."Riot at Munich Lecture", New York Times, 17 May 1922. Unable to guarantee his safety, Steiner's agents cancelled his next lecture tour. The 1923 Beer Hall Putsch in Munich led Steiner to give up his residence in Berlin, saying that if those responsible for the attempted coup (Hitler's Nazi party) came to power in Germany, it would no longer be possible for him to enter the country.

From 1923 on, Steiner showed signs of increasing frailness and illness. He nonetheless continued to lecture widely, and even to travel; especially towards the end of this time, he was often giving two, three or even four lectures daily for courses taking place concurrently. Many of these lectures focused on practical areas of life such as education.

Increasingly ill, he held his last lecture in late September, 1924. He continued work on his autobiography during the last months of his life; he died on 30 March 1925.

 Spiritual research 
Steiner first began speaking publicly about spiritual experiences and phenomena in his 1899 lectures to the Theosophical Society. By 1901 he had begun to write about spiritual topics, initially in the form of discussions of historical figures such as the mystics of the Middle Ages. By 1904 he was expressing his own understanding of these themes in his essays and books, while continuing to refer to a wide variety of historical sources.

Steiner aimed to apply his training in mathematics, science, and philosophy to produce rigorous, verifiable presentations of those experiences. He believed that through freely chosen ethical disciplines and meditative training, anyone could develop the ability to experience the spiritual world, including the higher nature of oneself and others. Steiner believed that such discipline and training would help a person to become a more moral, creative and free individual – free in the sense of being capable of actions motivated solely by love. His philosophical ideas were affected by Franz Brentano, with whom he had studied, as well as by Fichte, Hegel, Schelling, and Goethe's phenomenological approach to science.Bockemühl, J., Toward a Phenomenology of the Etheric World 

Steiner used the word Geisteswissenschaft (from Geist = mind or spirit, Wissenschaft = science), a term originally coined by Wilhelm Dilthey as a descriptor of the humanities, in a novel way, to describe a systematic ("scientific") approach to spirituality. Steiner used the term Geisteswissenschaft, generally translated into English as "spiritual science," to describe a discipline treating the spirit as something actual and real, starting from the premise that it is possible for human beings to penetrate behind what is sense-perceptible. He proposed that psychology, history, and the humanities generally were based on the direct grasp of an ideal reality, and required close attention to the particular period and culture which provided the distinctive character of religious qualities in the course of the evolution of consciousness. In contrast to William James' pragmatic approach to religious and psychic experience, which emphasized its idiosyncratic character, Steiner focused on ways such experience can be rendered more intelligible and integrated into human life.

Steiner proposed that an understanding of reincarnation and karma was necessary to understand psychology and that the form of external nature would be more comprehensible as a result of insight into the course of karma in the evolution of humanity. Beginning in 1910, he described aspects of karma relating to health, natural phenomena and free will, taking the position that a person is not bound by his or her karma, but can transcend this through actively taking hold of one's own nature and destiny. In an extensive series of lectures from February to September 1924, Steiner presented further research on successive reincarnations of various individuals and described the techniques he used for karma research.These lectures were published as Karmic Relationships: Esoteric Studies

 Breadth of activity 
After the First World War, Steiner became active in a wide variety of cultural contexts. He founded a number of schools, the first of which was known as the Waldorf school, which later evolved into a worldwide school network. He also founded a system of organic agriculture, now known as biodynamic agriculture, which was one of the first forms of modern organic farming. His work in medicine is based in pseudoscience and occult ideas. Even though his medical ideas led to the development of a broad range of complementary medications and supportive artistic and biographic therapies, they are considered ineffective though harmless by the medical community. Numerous homes for children and adults with developmental disabilities based on his work (including those of the Camphill movement) are found in Africa, Europe, and North America. His paintings and drawings influenced Joseph Beuys and other modern artists. His two Goetheanum buildings are considered significant examples of modern architecture,Rudolf Steiner , Great Buildings OnlineHortola, Policarp. "The Aesthetics of haemotaphonomy: A study of the stylistic parallels between a science and literature and the visual arts". Eidos 2009, n.10, pp. 162-193 and other anthroposophical architects have contributed thousands of buildings to the modern scene.

Steiner's literary estate is broad. Steiner's writings, published in about forty volumes, include books, essays, four plays ('mystery dramas'), mantric verse, and an autobiography. His collected lectures, making up another approximately 300 volumes, discuss a wide range of themes. Steiner's drawings, chiefly illustrations done on blackboards during his lectures, are collected in a separate series of 28 volumes. Many publications have covered his architectural legacy and sculptural work.

 Education 

As a young man, Steiner was a private tutor and a lecturer on history for the Berlin Arbeiterbildungsschule, an educational initiative for working class adults. Soon thereafter, he began to articulate his ideas on education in public lectures, culminating in a 1907 essay on The Education of the Child in which he described the major phases of child development which formed the foundation of his approach to education. His conception of education was influenced by the Herbartian pedagogy prominent in Europe during the late nineteenth century, though Steiner criticized Herbart for not sufficiently recognizing the importance of educating the will and feelings as well as the intellect.

In 1919, Emil Molt invited him to lecture to his workers at the Waldorf-Astoria cigarette factory in Stuttgart. Out of these lectures came the first Waldorf School. In 1922, Steiner presented these ideas at a conference called for this purpose in Oxford by Professor Millicent Mackenzie. He subsequently presented a teacher training course at Torquay in 1924 at an Anthroposophy Summer School organised by Eleanor Merry. The Oxford Conference and the Torquay teacher training led to the founding of the first Waldorf schools in Britain. During Steiner's lifetime, schools based on his educational principles were also founded in Hamburg, Essen, The Hague and London; there are now more than 1000 Waldorf schools worldwide.

 Biodynamic agriculture 

In 1924, a group of farmers concerned about the future of agriculture requested Steiner's help. Steiner responded with a lecture series on an ecological and sustainable approach to agriculture that increased soil fertility without the use of chemical fertilizers and pesticides. Steiner's agricultural ideas promptly spread and were put into practice internationally and biodynamic agriculture is now practiced in Europe, North America, South America, Africa, Asia and Australasia.Groups in N. America, List of Demeter certifying organizations, Other biodynamic certifying organization, Some farms in the world

A central aspect of biodynamics is that the farm as a whole is seen as an organism, and therefore should be a largely self-sustaining system, producing its own manure and animal feed. Plant or animal disease is seen as a symptom of problems in the whole organism. Steiner also suggested timing such agricultural activities as sowing, weeding, and harvesting to utilize the influences on plant growth of the moon and planets; and the application of natural materials prepared in specific ways to the soil, compost, and crops, with the intention of engaging non-physical beings and elemental forces. He encouraged his listeners to verify such suggestions empirically, as he had not yet done.

In a 2002 newspaper editorial, Peter Treue, agricultural researcher at the University of Kiel, characterized biodynamics as pseudoscience and argued that similar or equal results can be obtained using standard organic farming principles. He wrote that some biodynamic preparations more resemble alchemy or magic akin to geomancy.

 Anthroposophical medicine 

From the late 1910s, Steiner was working with doctors to create a new approach to medicine. In 1921, pharmacists and physicians gathered under Steiner's guidance to create a pharmaceutical company called Weleda which now distributes naturopathic medical and beauty products worldwide. At around the same time, Dr. Ita Wegman founded a first anthroposophic medical clinic (now the Ita Wegman Clinic) in Arlesheim. Anthroposophic medicine is practiced in some 80 countries.  It is a form of alternative medicine based on pseudoscientific and occult notions.

 Social reform

For a period after World War I, Steiner was active as a lecturer on social reform. A petition expressing his basic social ideas was widely circulated and signed by many cultural figures of the day, including Hermann Hesse.

In Steiner's chief book on social reform, Toward Social Renewal, he suggested that the cultural, political and economic spheres of society need to work together as consciously cooperating yet independent entities, each with a particular task: political institutions should be democratic, establish political equality and protect human rights; cultural institutions should nurture the free and unhindered development of science, art, education and religion; and economic institutions should enable producers, distributors, and consumers to cooperate voluntarily to provide efficiently for society's needs. He saw this division of responsibility as a vital task which would take up consciously the historical trend toward the mutual independence of these three realms. Steiner also gave suggestions for many specific social reforms.

Steiner proposed that societal well-being fundamentally depends upon a relationship of mutuality between the individuals and the community as a whole:

He expressed another aspect of this in the following motto:

 Architecture and visual arts 

Steiner designed 17 buildings, including the First and Second Goetheanums. These two buildings, built in Dornach, Switzerland, were intended to house significant theater spaces as well as a "school for spiritual science". Three of Steiner's buildings have been listed amongst the most significant works of modern architecture.

His primary sculptural work is The Representative of Humanity (1922), a nine-meter high wood sculpture executed as a joint project with the sculptor Edith Maryon. This was intended to be placed in the first Goetheanum. It shows a central human figure, the "Representative of Humanity," holding a balance between opposing tendencies of expansion and contraction personified as the beings of Lucifer and Ahriman.The Representative of Humanity Between Lucifer and Ahriman, The Wooden Model at the Goetheanum, Judith von Halle, John Wilkes (2010)  from the German Die Holzplastik des Goetheanum (2008)  It was intended to show, in conscious contrast to Michelangelo's Last Judgment, Christ as mute and impersonal such that the beings that approach him must judge themselves. The sculpture is now on permanent display at the Goetheanum.

Steiner's blackboard drawings were unique at the time and almost certainly not originally intended as art works. Joseph Beuys' work, itself heavily influenced by Steiner, has led to the modern understanding of Steiner's drawings as artistic objects.

 Performing arts 

Steiner wrote four mystery plays between 1909 and 1913: The Portal of Initiation, The Souls' Probation, The Guardian of the Threshold and The Soul's Awakening, modeled on the esoteric dramas of Edouard Schuré, Maurice Maeterlinck, and Johann Wolfgang von Goethe. Steiner's plays continue to be performed by anthroposophical groups in various countries, most notably (in the original German) in Dornach, Switzerland and (in English translation) in Spring Valley, New York and in Stroud and Stourbridge in the U.K.

In collaboration with Marie von Sivers, Steiner also founded a new approach to acting, storytelling, and the recitation of poetry. His last public lecture course, given in 1924, was on speech and drama. The Russian actor, director, and acting coach Michael Chekhov based significant aspects of his method of acting on Steiner's work.Richard Solomon, Michael Chekhov and His Approach to Acting in Contemporary Performance Training , MA thesis University of Maine, 2002

Together with Marie von Sivers, Rudolf Steiner also developed the art of eurythmy, sometimes referred to as "visible speech and song". According to the principles of eurythmy, there are archetypal movements or gestures that correspond to every aspect of speech – the sounds (or phonemes), the rhythms, and the grammatical function – to every "soul quality" – joy, despair, tenderness, etc. – and to every aspect of music – tones, intervals, rhythms, and harmonies.

Esoteric schools

Steiner was founder and leader of the following: 
 His independent Esoteric School of the Theosophical Society, founded in 1904. This school continued after the break with Theosophy but was disbanded at the start of World War I.
 A lodge called Mystica Aeterna within the Masonic Order of Memphis and Mizraim, which Steiner led from 1906 until around 1914. Steiner added to the Masonic rite a number of Rosicrucian references. 
 The School of Spiritual Science of the Anthroposophical Society, founded in 1923 as a further development of his earlier Esoteric School. This was originally constituted with a general section and seven specialized sections for education, literature, performing arts, natural sciences, medicine, visual arts, and astronomy. Steiner gave members of the School the first Lesson for guidance into the esoteric work in February 1924. Though Steiner intended to develop three "classes" of this school, only the first of these was developed in his lifetime (and continues today). An authentic text of the written records on which the teaching of the First Class was based was published in 1992.

 Philosophical ideas
 Goethean science 

Goethean science is not science, but pseudoscience. According to Dan Dugan, Steiner was a champion of the following pseudoscientific claims:

wrong color theory;
obtuse criticism of the theory of relativity;
weird ideas about motions of the planets;
supporting vitalism;
doubting germ theory;
weird approach to physiological systems;
"the heart is not a pump".

In his commentaries on Goethe's scientific works, written between 1884 and 1897, Steiner presented Goethe's approach to science as essentially phenomenological in nature, rather than theory- or model-based. He developed this conception further in several books, The Theory of Knowledge Implicit in Goethe's World-Conception (1886) and Goethe's Conception of the World (1897), particularly emphasizing the transformation in Goethe's approach from the physical sciences, where experiment played the primary role, to plant biology, where both accurate perception and imagination were required to find the biological archetypes (Urpflanze). He postulated that Goethe had sought, but been unable to fully find, the further transformation in scientific thinking necessary to properly interpret and understand the animal kingdom. Steiner emphasized the role of evolutionary thinking in Goethe's discovery of the intermaxillary bone in human beings; Goethe expected human anatomy to be an evolutionary transformation of animal anatomy. Steiner defended Goethe's qualitative description of color as arising synthetically from the polarity of light and darkness, in contrast to Newton's particle-based and analytic conception.

 Knowledge and freedom 

Steiner approached the philosophical questions of knowledge and freedom in two stages. In his dissertation, published in expanded form in 1892 as Truth and Knowledge, Steiner suggests that there is an inconsistency between Kant's philosophy, which posits that all knowledge is a representation of an essential verity inaccessible to human consciousness, and modern science, which assumes that all influences can be found in the sensory and mental world to which we have access. Steiner considered Kant's philosophy of an inaccessible beyond ("Jenseits-Philosophy") a stumbling block in achieving a satisfying philosophical viewpoint.

Steiner postulates that the world is essentially an indivisible unity, but that our consciousness divides it into the sense-perceptible appearance, on the one hand, and the formal nature accessible to our thinking, on the other. He sees in thinking itself an element that can be strengthened and deepened sufficiently to penetrate all that our senses do not reveal to us. Steiner thus considered what appears to human experience as a division between the spiritual and natural worlds to be a conditioned result of the structure of our consciousness, which separates perception and thinking. These two faculties give us not two worlds, but two complementary views of the same world; neither has primacy and the two together are necessary and sufficient to arrive at a complete understanding of the world. In thinking about perception (the path of natural science) and perceiving the process of thinking (the path of spiritual training), it is possible to discover a hidden inner unity between the two poles of our experience. Truth, for Steiner, is paradoxically both an objective discovery and yet "a free creation of the human spirit, that never would exist at all if we did not generate it ourselves. The task of understanding is not to replicate in conceptual form something that already exists, but rather to create a wholly new realm, that together with the world given to our senses constitutes the fullness of reality."

In The Philosophy of Freedom, Steiner further explores potentials within thinking: freedom, he suggests, can only be approached gradually with the aid of the creative activity of thinking. Thinking can be a free deed; in addition, it can liberate our will from its subservience to our instincts and drives. Free deeds, he suggests, are those for which we are fully conscious of the motive for our action; freedom is the spiritual activity of penetrating with consciousness our own nature and that of the world, and the real activity of acting in full consciousness. This includes overcoming influences of both heredity and environment: "To be free is to be capable of thinking one's own thoughts – not the thoughts merely of the body, or of society, but thoughts generated by one's deepest, most original, most essential and spiritual self, one's individuality."

Steiner affirms Darwin's and Haeckel's evolutionary perspectives but extended this beyond its materialistic consequences; he sees human consciousness, indeed, all human culture, as a product of natural evolution that transcends itself. For Steiner, nature becomes self-conscious in the human being. Steiner's description of the nature of human consciousness thus closely parallels that of Solovyov.

 Spiritual science 

In his earliest works, Steiner already spoke of the "natural and spiritual worlds" as a unity. From 1900 on, he began lecturing about concrete details of the spiritual world(s), culminating in the publication in 1904 of the first of several systematic presentations, his Theosophy: An Introduction to the Spiritual Processes in Human Life and in the Cosmos. As a starting point for the book Steiner took a quotation from Goethe, describing the method of natural scientific observation, while in the Preface he made clear that the line of thought taken in this book led to the same goal as that in his earlier work, The Philosophy of Freedom.

In the years 1903–1908 Steiner maintained the magazine Lucifer-Gnosis and published in it essays on topics such as initiation, reincarnation and karma, and knowledge of the supernatural world. Some of these were later collected and published as books, such as How to Know Higher Worlds (1904–5) and Cosmic Memory. The book An Outline of Esoteric Science was published in 1910. Important themes include:
 the human being as body, soul and spirit;
 the path of spiritual development;
 spiritual influences on world-evolution and history; and
 reincarnation and karma.

Steiner emphasized that there is an objective natural and spiritual world that can be known, and that perceptions of the spiritual world and incorporeal beings are, under conditions of training comparable to that required for the natural sciences, including self-discipline, replicable by multiple observers. It is on this basis that spiritual science is possible, with radically different epistemological foundations than those of natural science. He believed that natural science was correct in its methods but one-sided for exclusively focusing on sensory phenomena, while mysticism was vague in its methods, though seeking to explore the inner and spiritual life. Anthroposophy was meant to apply the systematic methods of the former to the content of the latterOne of Steiner's teachers, Franz Brentano, had famously declared that "The true method of philosophy can only be the method of natural science" (Walach, Harald, "Criticism of Transpersonal Psychology and Beyond", in The Wiley-Blackwell Handbook of Transpersonal Psychology, ed. H. L. Friedman and G. Hartelius. P. 45.)

For Steiner, the cosmos is permeated and continually transformed by the creative activity of non-physical processes and spiritual beings. For the human being to become conscious of the objective reality of these processes and beings, it is necessary to creatively enact and reenact, within, their creative activity. Thus objective spiritual knowledge always entails creative inner activity. Steiner articulated three stages of any creative deed:
 Moral intuition: the ability to discover or, preferably, develop valid ethical principles;
 Moral imagination: the imaginative transformation of such principles into a concrete intention applicable to the particular situation (situational ethics); and
 Moral technique: the realization of the intended transformation, depending on a mastery of practical skills.

Steiner termed his work from this period onwards Anthroposophy. He emphasized that the spiritual path he articulated builds upon and supports individual freedom and independent judgment; for the results of spiritual research to be appropriately presented in a modern context they must be in a form accessible to logical understanding, so that those who do not have access to the spiritual experiences underlying anthroposophical research can make independent evaluations of the latter's results. Spiritual training is to support what Steiner considered the overall purpose of human evolution, the development of the mutually interdependent qualities of love and freedom.

 Steiner and Christianity 
Steiner appreciated the ritual of the mass he experienced while serving as an altar boy from school age until he was ten years old, and this experience remained memorable for him as a genuinely spiritual one, contrasting with his irreligious family life. As a young adult, Steiner had no formal connection to organized religion. In 1899, he experienced what he described as a life-transforming inner encounter with the being of Christ. Steiner was then 38, and the experience of meeting Christ occurred after a tremendous inner struggle. To use Steiner's own words, the "experience culminated in my standing in the spiritual presence of the Mystery of Golgotha in a most profound and solemn festival of knowledge." His relationship to Christianity thereafter remained entirely founded upon personal experience, and thus both non-denominational and strikingly different from conventional religious forms.

 Christ and human evolution 
Steiner describes Christ as the unique pivot and meaning of earth's evolutionary processes and human history, redeeming the Fall from Paradise. He understood the Christ as a being that unifies and inspires all religions, not belonging to a particular religious faith. To be "Christian" is, for Steiner, a search for balance between polarizing extremes and the ability to manifest love in freedom.

Central principles of his understanding include:
The being of Christ is central to all religions, though called by different names by each.
Every religion is valid and true for the time and cultural context in which it was born.
Historical forms of Christianity need to be transformed in our times in order to meet the ongoing evolution of humanity.

In Steiner's esoteric cosmology, the spiritual development of humanity is interwoven in and inseparable from the cosmological development of the universe. Continuing the evolution that led to humanity being born out of the natural world, the Christ being brings an impulse enabling human consciousness of the forces that act creatively, but unconsciously, in nature.

 Divergence from conventional Christian thought 
Steiner's views of Christianity diverge from conventional Christian thought in key places, and include gnostic elements. However, unlike many gnostics, Steiner affirms the unique and actual physical Incarnation of Christ in Jesus at the beginning of the Christian era.

One of the central points of divergence with conventional Christian thought is found in Steiner's views on reincarnation and karma.

Steiner also posited two different Jesus children involved in the Incarnation of the Christ: one child descended from Solomon, as described in the Gospel of Matthew; the other child from Nathan, as described in the Gospel of Luke. He references in this regard the fact that the genealogies in these two gospels list twenty-six (Luke) to forty-one (Matthew) completely different ancestors for the generations from David to Jesus.

Steiner's view of the second coming of Christ is also unusual. He suggested that this would not be a physical reappearance, but rather, meant that the Christ being would become manifest in non-physical form, in the "etheric realm" – i.e. visible to spiritual vision and apparent in community life – for increasing numbers of people, beginning around the year 1933. He emphasized that the future would require humanity to recognize this Spirit of Love in all its genuine forms, regardless of how this is named. He also warned that the traditional name, "Christ", might be used, yet the true essence of this Being of Love ignored.

 The Christian Community 
In the 1920s, Steiner was approached by Friedrich Rittelmeyer, a Lutheran pastor with a congregation in Berlin, who asked if it was possible to create a more modern form of Christianity. Soon others joined Rittelmeyer – mostly Protestant pastors and theology students, but including several Roman Catholic priests. Steiner offered counsel on renewing the spiritual potency of the sacraments while emphasizing freedom of thought and a personal relationship to religious life. He envisioned a new synthesis of Catholic and Protestant approaches to religious life, terming this "modern, Johannine Christianity".

The resulting movement for religious renewal became known as "The Christian Community". Its work is based on a free relationship to Christ without dogma or policies. Its priesthood, which is open to both men and women, is free to preach out of their own spiritual insights and creativity.

Steiner emphasized that the resulting movement for the renewal of Christianity was a personal gesture of help to a movement founded by Rittelmeyer and others independently of his anthroposophical work. The distinction was important to Steiner because he sought with Anthroposophy to create a scientific, not faith-based, spirituality. He recognized that for those who wished to find more traditional forms, however, a renewal of the traditional religions was also a vital need of the times.

 Reception 

Steiner's work has influenced a broad range of notable personalities. These include:
 philosophers Albert Schweitzer, Owen Barfield and Richard Tarnas; 
 writers Saul Bellow, Andrej Belyj,Judith Wermuth-Atkinson, The Red Jester: Andrei Bely's Petersburg as a Novel of the European Modern (2012).  Michael Ende, Selma Lagerlöf, Edouard Schuré, David Spangler, and William Irwin Thompson;
 child psychiatrist Eva Frommer;
 economist Leonard Read;
 ecologist Rachel Carson;
 artists Joseph Beuys, Wassily Kandinsky, and Murray Griffin;
 esotericist and educationalist George Trevelyan;
 actor and acting teacher Michael Chekhov;
 cinema director Andrei Tarkovsky;
 composers Jonathan Harvey and Viktor Ullmann; and
 conductor Bruno Walter.

Olav Hammer, though sharply critical of esoteric movements generally, terms Steiner "arguably the most historically and philosophically sophisticated spokesperson of the Esoteric Tradition."

Albert Schweitzer wrote that he and Steiner had in common that they had "taken on the life mission of working for the emergence of a true culture enlivened by the ideal of humanity and to encourage people to become truly thinking beings".

Anthony Storr stated about Rudolf Steiner's Anthroposophy: "His belief system is so eccentric, so unsupported by evidence, so manifestly bizarre, that rational skeptics are bound to consider it delusional.... But, whereas Einstein's way of perceiving the world by thought became confirmed by experiment and mathematical proof, Steiner's remained intensely subjective and insusceptible of objective confirmation."

Robert Todd Carroll has said of Steiner that "Some of his ideas on education – such as educating the handicapped in the mainstream – are worth considering, although his overall plan for developing the spirit and the soul rather than the intellect cannot be admired". Steiner's translators have pointed out that his use of Geist includes both mind and spirit, however, as the German term Geist can be translated equally properly in either way.

The 150th anniversary of Rudolf Steiner's birth was marked by the first major retrospective exhibition of his art and work, 'Kosmos - Alchemy of the everyday'. Organized by Vitra Design Museum, the traveling exhibition presented many facets of Steiner's life and achievements, including his influence on architecture, furniture design, dance (Eurythmy), education, and agriculture (Biodynamic agriculture). The exhibition opened in 2011 at the Kunstmuseum in Stuttgart, Germany,

 Scientism 

Olav Hammer has criticized as scientism Steiner's claim to use scientific methodology to investigate spiritual phenomena that were based upon his claims of clairvoyant experience. Steiner regarded the observations of spiritual research as more dependable (and above all, consistent) than observations of physical reality. However, he did consider spiritual research to be fallible and held the view that anyone capable of thinking logically was in a position to correct errors by spiritual researchers.

 Race and ethnicity
 
Steiner's work includes both universalist, humanist elements and racial assumptions. Due to the contrast and even contradictions between these elements, one commentator argues: "whether a given reader interprets Anthroposophy as racist or not depends upon that reader's concerns". Steiner considered that by dint of its shared language and culture, each people has a unique essence, which he called its soul or spirit. He saw race as a physical manifestation of humanity's spiritual evolution, and at times discussed race in terms of complex hierarchies that were largely derived from 19th century biology, anthropology, philosophy and theosophy. However, he consistently and explicitly subordinated race, ethnicity, gender, and indeed all hereditary factors, to individual factors in development. For Steiner, human individuality is centered in a person's unique biography, and he believed that an individual's experiences and development are not bound by a single lifetime or the qualities of the physical body.

Steiner occasionally characterized specific races, nations and ethnicities in ways that have been deemed racist by critics. This includes descriptions by him of certain races and ethnic groups as flowering, others as backward, or destined to degenerate or disappear. He presented explicitly hierarchical views of the spiritual evolution of different races, including—at times, and inconsistently—portraying the white race, European culture or Germanic culture as representing the high point of human evolution as of the early 20th century, although he did describe them as destined to be superseded by future cultures.

Throughout his life Steiner consistently emphasized the core spiritual unity of all the world's peoples and sharply criticized racial prejudice. He articulated beliefs that the individual nature of any person stands higher than any racial, ethnic, national or religious affiliation. His belief that race and ethnicity are transient and superficial, and not essential aspects of the individual, was partly rooted in his conviction that each individual reincarnates in a variety of different peoples and races over successive lives, and that each of us thus bears within him or herself the heritage of many races and peoples.Eugen Blume, "Joseph Beuys". In Kugler and Baur, Rudolf Steiner in Kunst und Architektur, , p. 186 Toward the end of his life, Steiner predicted that race will rapidly lose any remaining significance for future generations. In Steiner's view, culture is universal, and explicitly not ethnically based, and he vehemently criticized imperialism.

In the context of his ethical individualism, Steiner considered "race, folk, ethnicity and gender" to be general, describable categories into which individuals may choose to fit, but from which free human beings can and will liberate themselves.

 Judaism 
During the years when Steiner was best known as a literary critic, he published a series of articles attacking various manifestations of antisemitism and criticizing some of the most prominent anti-Semites of the time as "barbaric" and "enemies of culture"."Hammer und Hakenkreuz – Anthroposophie im Visier der völkischen Bewegung", Südwestrundfunk, 26 November 2004 Steiner suggested that Jewish cultural and social life had lost all contemporary relevance and promoted full assimilation of the Jewish people into the nations in which they lived. Steiner was a critic of his contemporary Theodor Herzl's goal of a Zionist state, and indeed of any ethnically determined state, as he considered ethnicity to be an outmoded basis for social life and civic identity.

Towards the end of Steiner's life and after his death, there were massive defamatory press attacks mounted on him by early Nazi Party leaders (including Adolf Hitler) and other right-wing nationalists. These criticized Steiner's thought and anthroposophy as being incompatible with Nazi racial ideology, and charged him with being influenced by his close connections with Jews and even (falsely) that he himself was Jewish.

But the truth was that while Anthroposophists complained of bad press, they were to a surprising extent let be by the Nazi regime, "including outspokenly supportive pieces in the Völkischer Beobachter". Sicherheitsdienst purists argued largely in vain against Anthroposophy. According to Staudenmaier, "The prospect of unmitigated persecution was held at bay for years in a tenuous truce between pro-anthroposophical and anti-anthroposophical Nazi factions."

An impact structure is a generally circular or craterlike geologic structure of deformed bedrock or sediment produced by impact on a planetary surface, whatever the stage of erosion of the structure. In contrast, an impact crater is the surface expression of an impact structure. In many cases, on Earth, the impact crater has been destroyed by erosion, leaving only the deformed rock or sediment of the impact structure behind. This is the fate of almost all old impact craters on Earth, unlike the ancient pristine craters preserved on the Moon and other geologically inactive rocky bodies with old surfaces in the Solar System. Impact structure is synonymous with the less commonly used term astrobleme meaning "star wound".

In an impact structure, the typical visible and topographic expressions of an impact crater are no longer obvious. Any meteorite fragments that may once have been present would be long since eroded away. Possible impact structures may be initially recognized by their anomalous geological character or geophysical expression. These may still be confirmed as impact structures by the presence of shocked minerals (particularly shocked quartz), shatter cones, geochemical evidence of extraterrestrial material or other methods.

Impact geology An autonomous agent is an intelligent agent operating on an owner's behalf but without any interference of that ownership entity. An intelligent agent, however appears according to an IBM white paper as:

Intelligent agents are software entities that carry out some set of operations on behalf of a user or another program with some degree of independence or autonomy, and in so doing, employ some knowledge or representation of the user's goals or desires.

Such an agent is a system situated in, and part of, a technical or natural environment, which senses any or some status of that environment, and acts on it in pursuit of its own agenda. Such an agenda evolves from drives (or programmed goals). The agent acts to change part of the environment or of its status and influences what it sensed.

Non-biological examples include intelligent agents, autonomous robots, and various software agents, including artificial life agents, and many computer viruses. Biological examples are not yet defined.

Agent appearance 
Lee et al. (2015) post safety issue from how the combination of external appearance and internal autonomous agent have impact on human reaction about autonomous vehicles. Their study explores the humanlike appearance agent and high level of autonomy are strongly correlated with social presence, intelligence, safety and trustworthy. In specific, appearance impact most on affective trust while autonomy impact most on both affective and cognitive domain of trust where cognitive trust is characterized by knowledge-based factors and affective trust ls largely emotion driven
