  • Hi Bill. My name is Thomas and I'm from Los Angeles. I would really like to hear your

  • opinion on whether or not we have free will in the conventional meaning. Is there really

  • an independent ego right here that is control of my every thought and action? I think Einstein

  • is a determinist so he does not believe in free will, but then there's the Heisenberg

  • Uncertainty Principle, although to my understanding the uncertainty is in our scientific instruments

  • and the inaccuracies of the measurements. Thank you.

  • Well, you covered a lot of ground in there but nobody knows about the nature of consciousness.

  • I think we have free will up to a point, but we are driven by deep, deep things like wanting

  • to get food, making more people, that is to say mating. And then I cannot help but notice

  • how much people from the same family tend to do the same things. Same families tend

  • to do the same things just anecdotally. But clearly I know I have made decisions based

  • on things that happened around me that I wouldn't have made without being informed by history

  • or what I'd noticed. I know I have. Now if that turns out not to be true I would be very

  • surprised. Now as far as the uncertainty principle goes,

  • uncertainty principle is roughly there's a quantum, there's an amount of energy below

  • which you can't measure. The old saying is you can know where the electron is or you

  • can know how fast it's going but you can't know both, not exactly because anything you

  • would use to measure it would inherently move the electron or change its speed. That's the

  • classic uncertainty principle at work. With that said, I am satisfied now, as an engineer

  • and scientist, that our brains are chemical reactions and chemical reactions, at some

  • level, depend on quantum mechanics, on the interaction of subatomic particles based on

  • this extraordinary thing called quantum electrodynamics, you alluded to it.

  • And so at some level there's randomness in what we think because we're made of chemicals

  • that have randomness. But largely human behavior is generally predictable. There's whole schools

  • full of psychologists and psychiatrists who study humans and they come across patterns,

  • and those patterns have got to be part of our brains and our free will has got to be

  • part of that. I mean I don't mean to skirt your question, but the nature of consciousness

  • you are living at a time when the nature of consciousness is not understood but it

  • may be very soon because we'll build computer models or computers that are as sophisticated

  • or as complicated or as messed up as human brains and they will behave the same way as

  • human brains, as long as they're plugged, the computers. Carry on.
