I am currently stuck with another conundrum (possibly up to late and not enough sleep) the whole tree falling in the forest thing...
without humans thinking would knowledge exist? Is knowledge something on its own... or do we have to acquire it to make it so?
The question comes back to what is meant by the term "knowledge?" Is this a species centric definition? Are we discussing knowledge simply confined to humans and human experience? If so:
I see a lot of misconception throughout this thread...much as trying to define "truth," "knowledge" seems to have implied meanings that are all across the map depending who you ask, and everyone assumes everyone else understands without question.
To me, knowledge isn't knowledge until it is learned, practiced and understood...intimately.
For example, how do you build a fire without matches or lighters? A lot of people would go on about how they "know" about using flint and steel or a bow and drill, blah blah blah...as if they "know" something. Yet ask if they have actually done so, *and* can do so now without hesitation or problem, and almost to a person they will say, "no." That is not knowledge. Knowledge is the conversion of learning into action or behavior. In other words, show me that you know. If you can't show me, you don't really know.
I can learn the basic principles behind nuclear reactions in a book...that doesn't mean I "know" how to build or operate a nuclear reactor.
I can say I know that tomato plants need sun, water and soil to grow, but until I can actually grow a garden I don't truthfully "know" anything about plants, let alone tomatoes.
I can say the earth is 6 billion years old, but unless I was there at the beginning I don't really "know" exactly how old the earth is.
I know, huh!
The last part about knowledge being something on its own suggests knowledge can be handed, like a tool, to a new owner...G!d handing the tablets to Moses on the mountain so to speak. I don't think it works like that. Knowledge in my way of thinking isn't something one just walks into like stale air in a cave, knowledge is earned by hard work and due diligence. The karate teacher doesn't just hand the knowledge of karate to the student; the karate teacher facilitates the learning and understanding of the student until that student is finally intimately familiar with the discipline, at which time the student can truthfully say he "knows" karate.
