In epistemology (theory of knowledge), a self-evident proposition is one that is known to be true by understanding its meaning without proof. Some epistemologists deny that any proposition can be self-evident. For most others, the belief that oneself is conscious is offered as an example of self-evidence. However, one's belief that someone else is conscious is not epistemically self-evident. The following proposition is often said to be self-evident: * ''A finite whole is greater than, or equal to, any of its parts A logical argument for a self-evident conclusion would demonstrate only an ignorance of the purpose of persuasively arguing for the conclusion based on one or more premises that differ from it (see ''ignoratio elenchi'' and begging the question). ==Analytic propositions== It is sometimes said that a self-evident proposition is one whose denial is self-contradictory. It is also sometimes said that an analytic proposition is one whose denial is self-contradictory. But the concepts do mean different things. Provided that one understands a self-evident proposition, one believes it, and self-evident propositions are not in need of proof. Likewise, that their denial is self-contradictory does not have to be proven. It is in this sense that the self-contradictions at work in self-evident and analytic propositions are different. Not all analytic propositions are self-evident, and it is sometimes claimed that not all self-evident propositions are analytic: e.g. my knowledge that I am conscious. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Self-evidence」の詳細全文を読む スポンサード リンク
