A priori
From Wikipedia, the free encyclopedia
Look up a priori in Wiktionary, the free dictionary.
A priori may refer to:
- A priori (law), based on deduction or hypothesis
- A priori (languages), a type of constructed language
- A priori (statistics), a knowledge of the actual population
- A priori (math modeling)
- A priori and a posteriori (philosophy), used to distinguish two types of propositional knowledge
- A priori (mathematics) - in mathematical literature, one often says proposition A "does not a priori imply" proposition B if any such implication would require some nontrivial reasoning. In particular, the question of whether proposition A implies proposition B a priori is independent of whether proposition A implies proposition B in fact.
