Beyond that, you’re arguing that unicorns exist because they exist conceptually – could we say then that God necessarily exists?
As a concept, yes, but I guess that depends on how you define him. As long as there aren’t any internal contradictions in the definition, he’ll exist as a concept. This isn’t the same as actually existing in the sense that he can affect our world, however.
But more importantly, let’s just return to the previous question. How do you distinguish between existence and non-existence? You’ve claimed that you can make that distinction.
Actually, I’ve pointed out that there is no distinction to make. There is no such thing as “non-existence.” If you can talk about something, it exists. If it doesn’t exist, there is no speaking of it or sensing it whatsoever.
If you’re instead asking, “How do you determine that something physically exists?” I would say, “I detect it through my senses or infer that it is acting on another object I detect.”
In this case, though, you’d need to provide evidence that pink elephants are mammals since that is part of your argument.
The evidence is the definition of “elephant.” Even though there surely isn’t an elephant in front of you at this moment, I can be sure that if there were, it would be a mammal because of the definition, else it wouldn’t be called an “elephant.”
- All beings exist.
- God is a being.
- Therefore, God exists.
The problem is that we only know God as a postulated being, not a being that actually exists. Similarly, pink elephants are postulated as being mammals, though they don’t actually exist as such (simply because they don’t exist in the physical world). The weakness of the argument, then, is the loose usage of “exists.” Does God exist in such a way that he could, say, lift my house off the ground? The argument doesn’t assure me of this whatsoever, because God is only defined as a being, but not known in the physical world as such.
My pink elephants may not be mammals at all. But you cannot observe or prove that wrong.
That problem would be resolved if we provided definitions. This is one reason why dictionaries were created, after all.
I know that a million dollars in U.S. cash in a safe deposit box with my name on it does not exist. It’s non-existent.
I could claim that the safe-deposit box exists “conceptually” but that is a different argument.
You just flatly contradicted yourself. You can’t say that something doesn’t exist at all but then contend that it exists in a certain way. Again, if you’re talking about physical existence, say so. If not, I’m going to assume you’re using the broadest definition of “existence.” I know that metaphysicians hate to define their terms, but you can do that much for me.
