Ideas would not exist without the existence of human beings. >>I argue the contrary position.In all the random interactions of matter, a self-replicating, evolvable combination sometimes emerges. Although the odds against it are astronomically small, there is an astronomical amount of matter and time for it to happen. This combination is an idea. Although it has physical form at any point in time, its existence does not depend on any particular piece of matter. As long as some matter is in this combination somewhere, the idea will continue to spread.Sometimes two of these ideas come into proximity and form a more complex idea. This is the process that resulted in human beings. But the ideas would exist, spread, combine and evolve without the accident of humans. Humans could not exist without the ideas.The particular set of ideas that humans are consiously aware of is those that have survival value, not those that are true in some abstract sense. "It would be fun to wrestle a saber-tooth tiger" died out in the paleolithic age, but not because it was false. "Food with lots of sugars and fats are good for you" survived and grew, despite its dubious veracity.Humans are carrying cases for ideas, probably to be soon replaced by better cases.
