Saint Anselm (1033-1109)

Proslogion

Translated by Sidney Norton Deane

In Behalf of the Fool

An answer to the argument of Anselm in the Proslogion
by Gaunilon, a monk of Marmoutier

Chapter 7

This, in the mean time, is the answer the fool could make to the arguments urged against him. When he is assured in the first place that this being is so great that its non-existence is not even conceivable, and that this in turn is proved on no other ground than the fact that otherwise it will not be greater than all things, the fool may make the same answer, and say:

When did I say that any such being exists in reality, that is, a being greater than all others?—that on this ground it should be proved to me that it also exists in reality to such a degree that it cannot even be conceived not to exist? Whereas in the first place it should be in some way proved that a nature which is higher, that is, greater and better, than all other natures, exists; in order that from this we may then be able to prove all attributes which necessarily the being that is greater and better than all possesses.

Moreover, it is said that the non-existence of this being is inconceivable. It might better be said, perhaps, that its non-existence, or the possibility of its non-existence, is unintelligible. For according to the true meaning of the word, unreal objects are unintelligible. Yet their existence is conceivable in the way in which the fool conceived of the non-existence of God. I am most certainly aware of my own existence; but I know, nevertheless, that my non-existence is possible. As to that supreme being, moreover, which God is, I understand without any doubt both his existence, and the impossibility of his non-existence. Whether, however, so long as I am most positively aware of my existence, I can conceive of my non-existence, I am not sure. But if I can, why can I not conceive of the non-existence of whatever else I know with the same certainty? If, however, I cannot, God will not be the only being of which it can be said, it is impossible to conceive of his non-existence.
