Many of our conscious choices are driven by subconscious desires, but not all.

Oh? And how do you know this?

I suppose it's logically possible that there are high-level priorities that are neither formed out of nor controlled by lower-level ones. But you couldn't know that even if that were the case, and as incoherent as most people are, they're still more consistent than your claim implies they should be.

It is much, much more elegant - and more compatible with what we know about cognition - to hold that the complex systems are built out of smaller, simpler systems over which the complex has no control.
