Oh and regarding, "You really can't make assertions if you don't believe they're true, or that there is [no?] truth at all": See, this is assuming that there is someone here (or there) and that there are assertions being made. What's more, I don't not believe that what I say/write is true or that there is truth at all.

I probably wrote that what seems to be happening is neither true nor false. This is blatantly obvious. The only way to honestly describe what seems to be happening is to say what it isn't. It definitely is neither true nor false. I could not, however, say that it is true or that it is false. It's alogical; not of logic; not defined or constrained by the concept of logic.
