Proof (truth)
A proof is Necessity and sufficiency, sufficient evidence or a sufficient argument for the truth of a proposition. The concept applies in a variety of disciplines, with both the nature of the evidence or justification and the criteria for sufficiency being area-dependent. In the area of oral and written communication such as conversation, Dialogue, dialog, rhetoric, etc., a proof is a persuasive perlocutionary act, perlocutionary speech act, which demonstrates the truth of a proposition. In any area of mathematics defined by its assumptions or axioms, a proof is an argument establishing a theorem of that area via accepted rules of inference starting from those axioms and from other previously established theorems. The subject of logic, in particular proof theory, formalizes and studies the notion of formal proof. In some areas of theory of justification, epistemology and existence of god, theology, the notion of Theory of justification, justification plays approximately the rol ...
