Now, I don't think there's any scientific grasp, any hint of an idea, as to how to explain free will. Suppose somebody argues that free will is an illusion. Okay. This could be the case, but I don't believe that it's the case. It could be. You have to be open-minded about the possibility. But you're going to need a very powerful argument to convince me that something as evident as free will is an illusion. Nobody's offered such an argument or even pretended to offer such an argument.
I was quite surprised by the last sentence. I wanted to explore his views on the topic, so I did a quick google search and I found this interview.
In the last couple of years ago, there were experiments showing that, when people make decisions, for example when I decide to pick up this cup, milliseconds before I make the decision, there is activity in the brain in the areas where you are going to act, i.e., milliseconds before I make the decision, the motor areas of the brain are already organized to pick the cup up. That evidence was used widely to conclude that this shows that we don’t have free will. But this doesn’t show anything of this sort. This just shows that decisions are unconscious. We all know that, if we think for a minute: of course decisions are unconscious. Some of them reach the level of consciousness, some of them we can’t even act on, but there is a lot there going on unconsciously, probably everything of interest, and we don’t know how to deal with it.
I don't understand what he means by unconscious decisions. Why is it so obvious to him that decisions are unconscious. To be honest, I don't understand his answers at all. His whole answer to the question "What is complexity in language? And in thought?" (Page 230) is beyond me. Any clarification of his position would be helpful.
