A priori

Hello friends welcome to series of Legal Maxims.

Introduction:

A legal maxim is an established principle or proposition of law. Legal maxims are generally in Latin language and are written in italics in a legal document.

A priori

Literal Translation:from earlier.

Definition and use: An argument derived from previous event.

Explanation:

It is a philosophical term. This term is used for with respect to reasoning to distinguish "necessary conclusions from first premises"; from "conclusions based on sense observation" which must follow it.

A prioriknowledge or justification is independent of experience, as with mathematics (3 + 2 = 5), tautologies ("All bachelors are unmarried"), and deduction from pure reason (e.g., ontological proofs).

A prioriknowledge is defined as knowledge that we can have "prior to experience". We do not need to observe how the world is to have such knowledge. Some examples are: "All bachelors are single", "All rectangles have four sides."

A priori is a Latin term meaning “from the cause to the effect.” It is a term of logic used to denote that when one generally accepted truth is shown to be a cause, another particular effect must necessarily follow. This phrase refers to a type of reasoning that examines given general principles to discover what particular facts or real-life observations can be derived from them. It is also known as deductive reasoning.

An a priori conclusion or judgment is one that is necessarily true, that is neither proved by nor capable of being disproved by experience, and that is known to be true by a process of reasoning independent of all factual evidence. The term is commonly used to indicate a judgment that is widely believed to be certain or that is introduced presumptively, without analysis or investigation. Thus to accuse someone of having assumed a fact or conclusion a prioriis often to disparage him or her for having failed to support a judgment through evidence or analysis.
