Syntheism is a new religious movement focused on how atheists and pantheists can achieve the same feelings of community and awe experienced in traditional theistic religions. The Syntheist Movement sees itself as the practical realisation of a philosophical ambition for a new religion dating back as far as Baruch Spinoza's pantheism in the 17th century and, most directly, British-American philosopher Alfred North Whitehead's pioneering work towards a process theology in his books Religion in the Making in 1926 and Process and Reality in 1929.
Syntheism may also be viewed as a response to the lack of atheistic and pantheistic belief systems in Western cultures, while being more abundant in Eastern cultures, for example as Zen Buddhism, Dzogchen Buddhism, Advaita Vedanta Hinduism, Zoroastrianism and Jainism.
