Old thread, but that doesn't make it worth answering, I suppose.
I think the answer is yes and no. And I think it's all a matter of opinion. So in my own opinion, yes. And no.
Yes, because the human mind is woven together by so many different threads of emotion and memory and impulse and there's the old "reptilian" brain competing with the newer, "higher" brain - the uniquely human part of the brain. All of these things create a sometimes confusing, often messy web or tapestry of intention/impulse/action/feeling, etc...
But then, humans can also be seen as primarily impulse-driven, not much different than other animals except that we are self-aware. We are still selfish in the same way all other animals are in that all-important need to preserve our own existence. We do the same things again and again, we write the same stories (literally and figuratively). We are like intelligent machines.
So... yes and no. I don't really know how you could go about answering only "yes" or "no" in a satisfying way.
