Ontological Argument


This is the third argument about god’s existence that I am going to look at. Of the last two arguments this is perhaps one that might be a bit of a head ache. Unlike the last two arguments this is what is called a priori—meaning an argument where the knowledge is gained independently of experience.

Descartes’

Imagine god as being perfect—what are all the qualities of perfection? Would you include existence as one of these qualities? Surly if something is perfect then is exists or else it is not really perfect because, it doesn’t have the quality of existence. It might have all other great qualities like beauty and kindness but, if it doesn’t exist then it is not perfect because things that exist are better than it. If I said to you do you want an imaginary cake or real one which one of them is better?

So the argument goes:

  1. God is perfect;
  2. Existence is a quality of perfection;
  3. Therefore if god is perfect he exists.

Well what is to be said if we say that he doesn’t exist? Well theists will say then what you are thinking of is not god because god is perfect and has to exist because he is perfection. This is called an argument!

Let us then define a thing called a ‘shunicorn’ it is exactly like a unicorn except we also say it is perfect therefore shunicorns exist[1]Shunicorns do not exist they are just made up and defined like this but this is the exact same argument used to ‘prove’ god exisits.

There is also argument about if Desecrates can use existence as a property of something. If I say ‘Mary is nice’ you assume that she exists because if she didn’t she couldn’t be nice—things that do not exist do not have properties. All existing things by nature exist we do not have to give them the property. There is a much more detailed attempt at what I have tried o say in this paragraph in Everitt’s[2]book—I am not going to try and do justice to it here.

Anselms’

Think of a something in which nothing greater can be thought of—now think of that thing existing—that is greater than what you were thinking of before; hence god exists.[3]

Right really not much to say on this one. Gaunilo[4] had a retort to this argument. Think of the greatest tropical island perfect in every way; now think of it existing wouldn’t that be better? Don’t pack your bags just yet!
