Ipse dixit

Ipse dixit (Latin for "he said it himself") is an assertion without proof, or a dogmatic expression of opinion.^[1]^[2]

The fallacy of defending a proposition by baldly asserting that it is "just how it is" distorts the argument by opting out of it entirely: the claimant declares an issue to be intrinsic, and not changeable.^[3]
