to see the future, it to be trapped--
once you see the future, and expect that future to be true, you are forever closing down millions of pathways

I understand what you're saying and agree- in part - but I believe you are defining time in a way that applies to an individual and that "glimpse" might well be a wish or something similar and it is indeed easy to close off other avenues because the "glimpse" is appealing.
I meant that it might be possible to have a glimpse of the future that is not personal, or even envisionable otherwise.
