When To Use

What does a priori mean?

A priori is a term applied to knowledge considered to be true without being based on previous experience or observation. In this sense, a priori describes knowledge that requires no evidence.A priori comes from Latin and literally translates as “from the previous” or “from the one before.”It’s often applied to things involving deductive reasoning, which uses general principles to arrive at specific facts or conclusions (from cause to effect).It can be used as an adjective, as in a priori knowledge, or as an adverb, as in We shouldn’t assume a priori that this is true.A priori contrasts with a posteriori, which literally translates as “from the latter” or “from the one behind” and is applied to things that are based on experience, observation, or existing data. A posteriori is applied to things that involve inductive reasoning, which uses specific instances to arrive at a general principle or law (from effect to cause).Both a priori and a posteriori are used in the context of reasoning and philosophy, especially epistemology, which is the philosophical study of knowledge. Both can also be used generally, though they’re often used formally.Example: Any proposition considered to be a priori knowledge should be carefully examined for bias. ​
