So, just out of curiosity, does the greatest conceivable hot dog exist?
Just follow the same logic as the ontological argument:
- We conceive of Awesome Dog as a hot dog than which no greater hot dog can be conceived.
- This hot dog than which no greater can be conceived either exists in the mind alone or both in the mind and in reality.
- Assume that this hot dog than which no greater can be conceived exists in the mind alone.
- Existing both in the mind and in reality is greater than existing solely in the mind.
- This being, existing in the mind alone, can also be conceived to exist in reality.
- This hot dog existing in the mind alone is not therefore the hot dog than which no greater can be conceived. (See statement 1 above.)
- Therefore, this hot dog than which no greater can be conceived exists in reality as well as exists in the mind.
The replacement of the term "being" makes absolutely no difference to the argument. The subdivision from "entity" to "class of entity" does not change anything about the structure of the argument - the greatest conceivable hot dog must, according to the logical syllogism, exist. After all, if it didn't, it would not be the greatest conceivable hot dog.
So does the greatest conceivable hot dog exist? The greatest conceivable dust mite? The greatest conceivable planet? The greatest conceivable
person?
The argument fails. A few problems:
- There's no reason to believe that such a "greatest conceivable being" is great enough to merit existence in reality, or that we can conceive of a being so great that it must necessarily also exist in reality.
- Treating existence as a quality may be fundamentally flawed in the first place, as something that does not exist cannot have qualities.
- The argument implies a greatest conceivable anything, and implies that we can literally imagine it, and it must necessarily exist, somewhere or somehow. This is an absurd conclusion.
