 C - Contradiction


Contradiction: Conjunction of a statement and its denial.

A contradiction in logic is never true, and thus deriving a contradiction from a set of statements shows one or more statements in the set are not true. See reductio ad absurdum.

Note this is a linguistic notion. Hegel and his followers (Marx, Lenin) introduced a lot of obscurity, nonsense, and indeed contradiction in their philosophy by claiming that there really are contradictions in reality. At best, this confuses oppositions and contradictions.
