Anybody here go around checking on "existence" ?
So what our language (and our cultural use of that language) states exists is what exists? Is this how you determine whether something does or does not exist?
No, but if the properties which something has to have to exist are exemplified, then that thing exists.
So, for example, if something has the properties of being omniscient, omnipotent, all-just, creator of the universe, then God exists. Those properties are exemplified. On the other hand, if nothing exemplifies those properties, then God does not exist.
Must anything have a particular set of unique properties? Maybe in the case of natural kinds (although, perhaps cats might have had three legs and been bald, or through some cruel twist of evolution, perhaps they could have had scales and slithered around on the ground), but not in the case of particular people. For example, it seems to me that Saul Kripke could not have been a walnut, being human (or at least humanoid), at least, seems to be an essential property of Kripke, but not much else. He might have studied literature instead of philosophy and never become a philosopher, he may even have died as a child. It seems to me that he might have existed without exemplifying almost all of the properties he currently exemplifies.
Quote:Thoughts. The number seven.
Are thoughts and numbers '
somethings'?
That is, it seems to me that the only things that exist, in a metaphysical sense, are objects, and thoughts and numbers aren't objects. Clearly, people have thoughts, but when I have a thought, it's not as if there is something that suddenly exists that could be pointed to.
Why would you ever suppose that you can point to whatever exists? Electrons and quarks exist. But they cannot be pointed to.
Surely pointing at any object, a table, a can of cola, a person, is a matter of pointing at electrons and quarks. That I can't point to a single quark or electron, or a small number of them, or even a large number of them if they are arranged in a certain manner, is an epistemic matter rather than a metaphysical one. It's a matter of not knowing where to point rather than there being nowhere to point to.
I don't think it is intelligible to say something exists unless it exists
somewhere (and somewhen); it seems to me to make the purported things that exist utterly mysterious.
Quote:I did not say that everything must have a unique set of properties. That is a metaphysical claim, and I have no idea whether it is true, or even how to determine whether it is true. But it is clear, is it not, that when we ask whether X exists, we are asking whether the properties we normally associate with X are instantiated (exemplified, or, in plain English, whether anything has them). Or, and Quine liked to put it: whether there is anything that "Xes". So, in case you do not know what the properties of a tapir are, you do still know that to ask whether tapirs exist is to ask whether there is anything that "tapirizes".
My point was that the metaphysical claim is implied by your semantic claim (that when we ask "does X exist?" we really mean "Does there exist an x such that ( blah x & blah x & blah x)?") if we are to retain common sense notions about how bits of language like names work. According to your view, "when we ask whether X exists, we are asking whether the properties we normally associate with X are instantiated". To use a completely unoriginal counterexample, one of the properties we "normally associate" with Godel is that he proved the incompleteness theorems, to be a Quinean Godelizer would be (in part) to be the prover of the incompleteness theorems. Now what if, in actual fact, Godel did not prove the incompleteness theorems, he stole it from a 'mathematical proof collective'? On your view we would seem to be committed to saying that Godel doesn't exist, or even more absurdly, that Godel does exist... as a 'mathematical proof collective'.
Of course, I'm not suggesting that something that exists need not have any properties. Anything that exists must have a set of properties, and moreover, if it is to be individuated from the other things that exist (i.e. if it is to be a
thing at all) it must have a unique set of properties. However, I see no reason why something cannot exist while at the same time exemplifying none of the properties people normally associate with it (with my above reservations about natural kinds).
