Matt Dilahunty On The Logical Absolutes

[bennyboy]

I think Hammy has it right. We forget that labels are words FOR something. If you have two different things, you use two labels. Therefore, if A=A, that means the same label can be applied to both A values. If A!=A, that means they aren't the same. This is not a philosophical or universal truth: it's simply a definition of what labels are. And anything that doesn't match that definition-- well, it just doesn't.
