So did you notice how you moved your own goal posts?Terrapin Station wrote: ↑Mon Feb 22, 2021 11:39 pm Again, I'm a nominalist. But nominalism doesn't imply that there are no things that are the same: namely, something is the same as itself (at a particular "point" in time, at least).
First you said "there are no things that are not the same". You used the word "things" in its plural form implying more than one thing.
Then you said "something is the same as itself...". You used the word "something" which is singular implying only one thing.
The same() function/operator/assertion is Binary. It takes TWO parameters (see arity if you are unfamiliar with this concept).
But any "something" is a SINGULAR entity, so you are talking about a Unary sameness, NOT Binary sameness.
So in your world-view would you say that the unary-same and binary-same are the same?
Asked another way: in your mind does this expression evaluate to True or False?
binary-same(unary-same, binary-same)
Yeah, but Philosophers don't know their heads from their ass. When people assert sameness they have a Binary operation in mind, not a Unary one.Terrapin Station wrote: ↑Mon Feb 22, 2021 11:39 pm That's what I'm talking about here--what's known as "numerical identity" in philosophy. In other words, just one whatever, at a particular spatiotemporal location.
In what practical situation/use-case have you ever found yourself needing to assert a thing's own sameness?
And THEN you are also assuming a "spatiotemporal location" which implies global (universal?) time coordinates. Your system of thought/logic (whatever it is) does not localise time. The implication of which is that all you can ever express in such a logic is causes and effects, but you can never express concurrent interactions.

At first, I thought your framing was deliberate. Now it seems you aren't even aware that you are imposing your frame on the discussion. Or are you aware and am I underestimating my interlocutor?
