Hitchens's razor is an epistemological razor that serves as a general rule for rejecting certain knowledge claims. It states:
What can be asserted without evidence can also be dismissed without evidence.[1][2][3][a]
The razor is credited to author and journalist Christopher Hitchens, although its provenance can be traced to the Latin Quod gratis asseritur, gratis negatur ("What is asserted gratuitously is denied gratuitously").[4] It implies that the burden of proof regarding the truthfulness of a claim lies with the one who makes the claim; if this burden is not met, then the claim is unfounded, and its opponents need not argue further in order to dismiss it. Hitchens used this phrase specifically in the context of refuting religious belief.[3]: 258
What can be asserted without evidence can also be dismissed without evidence.
