State of affairs (philosophy)

In philosophy, a state of affairs (German: Sachverhalt), also known as a situation, is a way the actual world must be in order to make some given proposition about the actual world true; in other words, a state of affairs is a truth-maker, whereas a proposition is a truth-bearer. Whereas states of affairs either obtain or fail-to-obtain, propositions are either true or false. Some philosophers understand the term "states of affairs" in a more restricted sense as a synonym for "fact". In this sense, there are no states of affairs that do not obtain.

The early Ludwig Wittgenstein and David Malet Armstrong are well known for their defence of a factualism, a position according to which the world is a world of facts and not a world of things.
