Ludwig Wittgenstein on A priori - Dictionary of Arguments
II 96 A Priori/Wittgenstein: that would have to be a set whose meaning guaranteed its truth - but the meaning requires that we verify the sentence. - ((s) verificationism: can then not accept analytic truths). II 96/97 A Priori/Wittgenstein: expressions that look a priori must be explained. >Explanation. - The same expression can be a sentence or a hypothesis - thus, the same expression may be equation or hypothesis. >Sentences, >Hypotheses. Equation: is necessary. >Equations. Geometry: in visual space, it is a priori that an equilateral triangle is equiangular - you cannot see one without seeing the other. Physical space: here it is not a priori, because the triangle may be inclined. II 98 A Priori/Seeming/Appearing/Wittgenstein: "This chair looks green" here, our certainty is of logical nature and a priori. --- III 233 A Priori/Necessity/Wittgenstein/Late/Flor: Wittgenstein does not concede the a priori grammatical sentences a form of absolute necessity. >Necessity._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
