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.
