Is it possible to perceive the future? Some astrologers say that they have seen the future through the stars; some claim to know events that will occur before they actually happen. Astrologers study the patterns of the stars to try to predict what's going to happen tomorrow. Do you think that astrology is a valid way of perception even though astrologers are not directly witnessing images of the future? If you supposedly know the future, can it ever be descriptive knowledge or is it always acquaintnace knowledge? because you can't claim to have known than an event will occur in the future because you always have to wait and confirm that it happens.
i.e. Let's say I predict that an asteroid will crash into Earth and destroy Antarctica exactly 1 week from now. Can I claim it as knowledge right now or would I have to wait 1 week and then confirm my prediction? Let's say that I perceived this through the stars, and it does turn out to be true; is it a valid way of perception or did I just make a wild guess and got it right?
