I actually did think about that (what you meant by the sentence),
and something seems "troubling" to me. I mean in logic, to be true
is to be true all the time. So in this example, we could say
it both ways, *at the same times*:

- we know what it means for "Snow is white" to be true.
- we know what it means for "Snow is *not* white" to be true.

and that seems logically "troubling" to me. Wouldn't you think so?

If you've seen white snow, then you know what "Snow is white"
means, and so you know what it means for "Snow is white" to be
true. If you've seen non-white snow, then you know what
"Snow is not white" means, and so you know what it means for
"Snow is not white" to be true. I don't understand what is
troubling you about this.

What then, in the name of logic, is to be true?
