To begin, thank you for replying Sicksixix. I will go further with the way you reason.

I completely agree that no amount of assumed understanding will prove what we are here for. Only living for yourself can prove anything, but still... someone with closed eyes won´t see anything of what he´s going through.

An effect has a cause. There´s a reason for which you replied to this post, though you may deny it or not be conscious of it. To give you another small example, if you drop a book on the floor, one of the effects is the sound it makes, though you may reply that you can´t prove anything.

Assuming that we are alone with reason doesn´t mean that we necessarily have to close our eyes to it either, or that we should limit ourselves in it.

If we would have never looked above, never would we have realized that there are other planets. It´s also because someone decided to look above that westerners found out that the Earth is round, though he was flamed (and that is the right word) for it because others claimed it was a false assumption. I guess they prefered to remain as the center of the universe.

If we didn´t make some assumptions, if we didn´t have dreams, nothing of what you know about human society would even exist. You would merely be "surviving," and still you would probably be dead, because you wouldn´t want to rely on the assumption that eating and drinking keep you alive. Though it may be a fact, you can´t absolutely prove it, you can only observe the effects and assume the causes.

Ideas may indeed change with the wind, and matter too though on a different scale, but what I am speaking of is not an idea or matter, it´s emptiness which is absence of all of these and which never changes, though I am using concepts to put it into words - to communicate, which is inevitable in communication. So if you seek an absolute cause for something, I guess it´s logical to assume that the first cause is what itself has no cause.

Anyway, I wonder why you assume that it´s so much about an "higher order?" Couldn´t it be as lower as higher?
