Input: Consider Input: Passage: According to the Catholic Encyclopedia of 1907-1912, materialism, defined as "a philosophical system which regards matter as the only reality in the world [...] denies the existence of God and the soul". Materialism, in this view, therefore becomes incompatible with most world religions, including Christianity, Judaism, and Islam. In such a context one can conflate materialism with atheism. Most of Hinduism and transcendentalism regards all matter as an illusion called Maya, blinding humans from knowing "the truth". Maya is the limited, purely physical and mental reality in which our everyday consciousness has become entangled. Maya gets destroyed for a person when s/he perceives Brahman with transcendental knowledge.


Output: Based on the above definition, materialism is consistent with what?
