The Ontological argument

A new page here in the Logic Museum on the ontological argument. Kicks off with Aristotle's proof of the existence of God from the Metaphysics, and Descartes argument from Meditations V. Coming later will be Augustine's argument (from On Free Will), Anselm's version of the ontological argument proper, Aquinas comments on Anselm's argument, and Scotus' very complex version of the cosmological argument.

The Square of Opposition

Just to draw attention to the page in the Logic Museum on the famous square. Plenty of material there, and plenty coming up, particularly of relevane to my dispute with Terence Parsons about the semantics of the O proposition.
