Imagination vs. Knowledge

This post is based on the following discussion:

In my opinion, this was sort of like the question, "What came first: the chicken or the egg?" It asks what the origin is of two fundamentally important mental tools. Is knowledge first because it is "all we know and understand"? Or is imagination first because it encompasses everything to know? This is a very tricky question to ask and to answer. I think that knowledge is what originally existed, as imagination is the "recreation" of what we know. If there was nothing to exist in the first place, what would we recreate in our minds? Thus, imagination is a tool that is an extension of knowledge, rather than being an original tool of our minds.

However, imagination is the more important of the two. Imagination is what allows humans to "see" rather than just "look." We can understand or at least process our knowledge with imagination. So, although it can be said that it can not survive without the existence of knowledge, imagination is still the more important of the two.
