god=TTWNGCBC, even the fool could accept this, greater to exist in re as well as in intellectu, if god is TTWNGCBC, he must exist in re and in intellectu

explain Anselms second proof.
to be a necessary being is greater than to be a contingent being, if god is TTWNGCBC, he must be a necessary being. impossible to think of a necessary being not existing, therefore god exists.

analogy of triangle; has predicates of 180 degee internal angles and 3 sides. without these its not a tringle. same as god requiring the predicate of existence.

how did Kant criticise the O.A?
existence is not a predicate. 'to exist' adds nothing to the definition of something. to descartes - if the triangle didnt exist in the first place, no need for predicates.

explain Gaunillo's criticism of the O.A.
analogy of an island: we can all imagine most perfect island, but this doesnt make it exist. we can always think of a better island, there is not just one 'perfect' island.

how did Anselm counter argue Gaunillo?
(stated in his second form) we are not arguning about contingent things eg islands, but necessary things; god. he argued 'reductio ad absurdum' (absurd to reject the propsition)
