The Syllogism

The Square of Opposition

The basic form of every proposition is 'S is P' where 'S' stands for subject, 'P' for predicate and 'is' for the copula.

What can be predicated universally of anything else, whether affirmatively of negatively, can be predicated in the same way of all that is contained under it.
