 D - Denial


Denial: Statement that is claimed to be not true, external negation.

In propostional logic, denial is often written as "~", as in "~P" i.e. "P is not true" or "it is not true that P". See negation for more about the subtleties involved in saying or writing "not", which is a basic logical term.

The general logical rule that applies here is that a statement and its denial cannot be both true (at the same time, in the same circumstances).
