Faith, derived from Latin fides and Old French feid,[1] is confidence or trust in a person, thing, or concept.[1][2] In the context of religion, one can define faith as "belief in God or in the doctrines or teachings of religion".[3] Religious people often think of faith as confidence based on a perceived degree of warrant,[4][5] while others who are more skeptical of religion tend to think of faith as simply belief without evidence.[6]

Evolutionary biologist Richard Dawkins criticizes all faith by generalizing from specific faith in propositions that conflict directly with scientific evidence.[95] He describes faith as belief without evidence; a process of active non-thinking. He states that it is a practice that only degrades our understanding of the natural world by allowing anyone to make a claim about nature that is based solely on their personal thoughts, and possibly distorted perceptions, that does not require testing against nature, has no ability to make reliable and consistent predictions, and is not subject to peer review.[96]

Philosophy professor Peter Boghossian argues tha

Philosophy professor Peter Boghossian argues that reason and evidence are the only way to determine which "claims about the world are likely true". Different religious traditions make different religious claims, and Boghossian asserts that faith alone cannot resolve conflicts between these without evidence. He gives as an example of the belief held by that Muslims that Muhammad (who died in the year 632) was the last prophet, and the contradictory belief held by Mormons that Joseph Smith (born in 1805) was a prophet. Boghossian asserts that faith has no "built-in corrective mechanism". For factual claims, he gives the example of the belief that the Earth is 4,000 years old. With only faith and no reason or evidence, he argues, there is no way to correct this claim if it is inaccurate. Boghossian advocates thinking of faith either as "belief without evidence" or "pretending to know things you don't know".[97]
