propositional knowledge

Also known as: knowing that

Quick Summary

In epistemology, propositional knowledge refers to knowing that something is the case, as opposed to knowing how to do something. This type of knowledge involves possessing specific pieces of information that can generally be conveyed to others.1

There are two main categories of knowledge:
* A priori knowledge is gained independently of experience, often through understanding the meanings of words. An example is knowing that "all husbands are married" because the definition of husband includes being married.23
* A posteriori knowledge requires empirical investigation or experience to be known. For instance, determining if "all Model T Fords are black" would necessitate looking at actual Model T Fords.23

Propositions can also be classified as logical or factual. Logical propositions can be reduced to logical truths, while factual propositions provide new information about the world.2
