Syllogism

syllogism noun etymology: from the word "silly" + -gism

Discovered by Aristotle, syllogisms are logical proofs that take the form
 * If all A are B
 * and all B are C
 * then all A are C.

Example:
 * If all syllogisms are stupid
 * and all this is a syllogism
 * then this is all stupid.

Syllogisms can be used to conclusively prove the existence of God.
