The Logic of Many-Valued Logics and Degrees of Truth

Quick fact

In classical logic, every proposition is either true or false, but many-valued logics allow for infinitely many truth values, such as 'completely true,' 'completely false,' and every degree in between—a feature that makes them powerful for handling vague predicates like 'tall' or 'heap'.

Why this is interesting

Is the statement 'the weather is hot' completely true or completely false when it's 30°C? What about 20°C? If you feel the need for a 'mostly' answer, you've just stumbled upon the motivation for many-valued logic.
