Episode notes

I think it's not at all inconceivable that we would be able to build computers that would have exactly this structure. But I mean, honestly, like on my computer, I can write a program where I'm not able to predict what the outcome is going to be but probably my Macintosh laptop is not going to be said to have free will just because I did that. We are those kinds of things nature gives us inputs, but we do have this role in choosing and making our own selves and choosing goals and so on and values. And someday we could build a computer or an Android that could also have those capabilities.

Physics is simple; people are complicated. But even people are ultimately physical systems, made of particles and forces that follow the rules of the Core Theory. How do we bridge the gap from one kind of description to another, explaining how someone we know and care about can also be “just” a set of quantum fields obeying impersonal laws? This is a hard question that comes up in a variety of forms — What is the “self”? Do we have free will, the ability to make choices? What are the moral and ethical ramifications of these considerations? Jenann Ismael is a philosopher at the leading edge of connecting human life to the fundamental laws of nature, for example in her recent book How Physics Makes Us Free. We talk about free will, consciousness, values, and other topics about which I’m sure everyone will simply agree.
