Re: How can we have ideas that do not exist in the "real" world?
Just as a rabbit uses its senses to go out and find a carrot, humans use their senses to set goals and follow dreams in pursuit of someday becoming what they wish to become, only more in depth. A rabbit can only think so far, can only react to its senses so quickley. To a rabbit, a basic circles exists in order to tell it when and how to eat, sleep, run, etc. To a human, a circle is imagined in such an efficient way that it may be put to effective usefulness. Evidence of this use can be derived from the 7 wonders of the ancient world that man created, based on imagination, ambition, and the intention of slowly progressing towards and a world in which ideal things are not so rare.
