In a recent podcast, Jordan Peterson and Sam Harris discuss dogmas - beliefs that people hold to be true, irrespective of evidence for or against them. They highlight the negative consequences of this - certain foundational beliefs lead to bad behaviours. Their discussion focuses on religions, which have written, well defined axioms and so are straightforward examples to discuss. However, I do not think their reasoning went far enough. It's not just religions that have foundational beliefs. Every person must have a set of beliefs they assume to be true without evidence.
