Truth
A proposition can have the following
truth values:
Philosophers argue a lot about what constitutes truth. For now,
we'll keep it simple:
- "P" is true if and only if P.
- "P" is false if and only if not P.
For example:
- The proposition "Snow is white" is true if and only if snow is white.
- The proposition "Snow is white" is false if and only if snow is not white.
In other words, a proposition is true if it correctly describes the
state of the world, and false if it incorrectly describes the state
of the world. This is known as Tarski's Theory of Truth.
