Grounds of Knowledge

Evidence

What is offered in support of a claim. Evidence is not the same as proof: it raises or lowers how likely a claim is, and its force depends on how it was gathered, what it was gathered for, and what else it is consistent with. Asking what would count as evidence against a claim is usually more revealing than listing evidence for it.

How claims are supported. These concepts ask what has to be in place before a claim earns the right to be believed, and what the difference is between a reason and a rationalisation.
