Abstract

There are several forms of the Ontological Argument, but it is more or less fair to say that all hang on the contention that the notion of a perfect being entails the existence of that being, since existence is involved in perfection. My first interest is in the word "perfect." The word, I think, is usually vague but it seems to me that, in the context of the proof, it has a meaning which turns out to be much more pedestrian than we would suspect. The argument, if it is valid, must assert that any perfect being would have to have every possible characteristic. It alleges that existence is a characteristic and it is, of course, over this that most debate has centered. It seems clear, however, that "perfect," as employed in the argument, merely means what we would call "complete" in less august transactions. In some forms of the proof, indeed, this is made somewhat clearer since the expression "greatest possible" being is substituted for "perfect." Ordinarily, no one would be tempted to pass lightly from the notion of "that which is complete" to the notion of "the deity." Both "perfect" and "greatest possible" appear to have moral connotations and "complete" usually does not. The slide, however, is made easier by the recurrent notion that evil is not a positive quality but merely the absence of another positive quality, usually goodness. If this view is held, it certainly does follow that whatever is "complete" must be "perfect" in the moral sense as well as in the other usual senses. It is not, here, my concern to pass judgment on this notion. I am, at the moment, merely trying to trace possible sources of confusion in the argument.
