You can't exactly predict the future unless you have all the information, even theoretically.

You can certainly predict portions of it (1=1 will continue to be true indefinitely, and that's just one example).

And, there is no need for predictions to be true, or claims of fact about whether there are or are not "reasons" for things. In fact, epistemically unsound claims such as this are very often the only type of speech ~allowed, as crazy as that may seem.

I don't see how what you're saying lets you "perceive the whole of the future in one gulp", or maybe it does, but you can't be confidant that it's the real future.

Oh, I was disagreeing with the proposition!! :)
