falsity
Quick Summary
In logic, falsity refers to the truth-value of a proposition that is not true. It is the opposite of truth. A statement known to be untrue and made with the intent to deceive is also considered a falsity. This can manifest as a lie, a myth, an illusion, or a misconception. In formal systems, truth-values, including falsity, are fundamental to evaluating the validity of statements. The concept of falsity is crucial in understanding logical connectives and constructing truth tables.12345
