Yes, I was mostly agreeing with you. From a physics point of view, there's no true randomness in the sense that some phenomenon would be truly unpredicable (*correcting my nerdy glasses*). Behind each apparent randomness is a law that may or may not be amenable to experiment. Even the white noise that I mentioned is not truly random because we can calculate its power spectrum. Quantum mechanical systems are not random either. So if all of these fundamental things are not random, why would a human/feelings/instincts be?
