  Buddhist philosophy begins with the thought of Gautama Buddha (fl. between sixth and fourth centuries BCE) and is preserved in the early Buddhist texts. It generally refers to the philosophical investigations that developed among various Buddhist schools in India and later spread throughout Asia through the Silk Road. Buddhist thought is trans-regional and trans-cultural. It is the dominant philosophical tradition in Tibet and Southeast Asian countries like Sri Lanka and Burma.
  
  Buddhism 's main concern is soteriological, defined as freedom from dukkha (unease). Because ignorance of the true nature of things is considered one of the roots of suffering, Buddhist thinkers concerned themselves with philosophical questions related to epistemology and the use of reason. Key Buddhist concepts include the Four Noble Truths, Anatta (not-self) a critique of a fixed personal identity, the transience of all things (Anicca), and a certain skepticism about metaphysical questions. Buddhist thinkers in India and subsequently in East Asia have covered topics as varied as phenomenology, ethics, ontology, epistemology, logic, and philosophy of time.
  
  Later Buddhist philosophical traditions developed complex phenomenological psychologies termed ' Abhidharma '. Mahayana philosophers such as Nagarjuna and Vasubandhu developed the theories of Shunyata (emptiness of all phenomena) and Vijnapti-matra (appearance only), a form of phenomenology or transcendental idealism. The Dignāga (c. 480–540) school of Pramāṇa promoted a complex form of epistemology and Buddhist logic. This tradition contributed to what has been called an "epistemological turn" in Indian philosophy. Through the work of Dharmakirti, this tradition of Buddhist logic has become the major epistemological system used in Tibetan Buddhist philosophy and debate.
  
  After the disappearance of Buddhism from India, these philosophical traditions continued to develop in the Tibetan Buddhist, East Asian Buddhist, and Theravada Buddhist traditions. In Tibet, the Indian tradition continued to be developed under the work of thinkers like Sakya Pandita, Tsongkhapa, and Ju Mipham. In East Asian Buddhism, new developments were led by East Asian Yogacara thinkers such as Paramartha, Xuanzang, and Wŏnhyo and East Asian Madhyamaka thinkers like Jizang. New sinitic schools also arose, like Tiantai, founded by Zhiyi, Huayan, defended by figures like Fazang, and Zen, which included philosophers like Guifeng Zongmi.
