|A priori: something that we can know without prior (empirical) investigation. Is the inventory of a priori certainties purely logical? Is a priori knowledge always necessary?_____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them. Instead, they are intended to give a short introduction to the contributions below. – Lexicon of Arguments. |
Necessary/not a priori: E.g. Goldbach’s conjecture: If it will turn out, then by necessity.
A priori/not necessary: E.g. determining the reference of the term "one meter": it is possible to know a priori that the length of this stick is one meter, and this would not be seen as a necessary truth.
Difference: a priori/necessary: Kripke: you could empirically discover the essence (e.g. water = H20)._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number. The corresponding books are indicated on the right hand side. ((s)…): Comment by the sender of the contribution. The note [Author1]Vs[Author2] or [Author]Vs[term] is an addition from the Dictionary of Arguments. If a German edition is specified, the page numbers refer to this edition.
