The finite and the infinite

Let's say that I work on the presupposition that finite cannot grasp the infinite. And if one does have complete grasp of the infinite, could one be described as infinite though possibly unequal to another infinite being,i.e. God (Georg Cantor, a mathematician in the late 19th/early 20th century argued that not all infinities are equal. So although an infinite set is infinitely large, it may not be as large as another infinite set.)

If we see ourselves as finite, how does that view effect our economic decisions, considering that our information may be grossly insufficient. If we are indeed infinite (or have perfect and complete economic knowledge, i.e. no risk), how would that effect our economic decisions. Please remember that economics does make an assumption that people will act rationally when provided with sufficient information.

Also, within our finite understanding of our finite selves, is there any relationship, causal or otherwise, between us and the infinite, and how does that translate economically?
