In
classical logic
, a
contradiction
consists of a logical incompatibility between two or more
propositions
. It occurs when the propositions, taken together, yield two
conclusions
which form the logical, usually opposite inversions of each other. Illustrating a general tendency in applied logic,
Aristotle's
law of
noncontradiction
states that "One cannot say of something that it is and that it is not in the same respect and at the same time."
By extension, outside of classical logic, one can speak of contradictions between actions when one presumes that their motives contradict each other.
