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.
Syntheism comes from the Greek syntheos (from syn- for with or creating with and -theos for god). It implies that the proper approach to the concept of God is that humanity has created, creates or will eventually create God – as opposed to the traditional monotheistic view that God created the world and humanity.
Besides the activism of The Syntheist Movement, a syntheistic approach to philosophy and religion has also been advocated by American philosopher Ray Kurzweil in his concept of the forthcoming Singularity. It is also supported by French philosopher Quentin Meillassoux in his idea of "God is a concept far too important to leave to the religious" in his book After Finitude.
