Only in Oxford: Free Will versus Determinism

 Did you freely decide to read this blog or was it simply inevitable? This free will argument engages my brain and has done for some time. Is everything pre-determined? Since our universe is determined by physical laws then given a fixed starting point everything must evolve according to those laws – that is determinism, we do not have free will. You did not decide to have eggs for breakfast this morning rather than cereal. You thought that you decided, but that thought was predetermined. When Jack the Ripper murdered all of those innocent people, it was not his fault, his actions were predetermined and not his responsibility!

I believe that we have free will and I can explain why. I believe that you can choose between eggs and cereal for breakfast and hence that we are responsible for our actions. Consequently, Jack the Ripper, if he had been found, should have faced the consequences.

Nevertheless, this very important issue needs exploration.That is why I decided to return to Oxford from Stow on the Wold in order to attend a lecture on it at St Margaret’s Institute which is quite near to our flat in North Oxford. The title was ‘Free will is not an illusion: biology against determinism’ and the speaker was Denis Noble. As usual I cut things fine, arriving about 3 minutes before the start. I was then faced, along with other disappointed attendees, by a large printed sign saying FULL UP. I was shocked. After all the lecture hall is large, it probably holds 70 or more, and the subject somewhat obscure. And so the title of this blog: “Only in Oxford”.

Undeterred, I returned to the flat and quickly found a video by Denis Noble on this self same subject. Watching it I quickly ascertained that this ancient, white haired, white browed academic believes that we do have free will - that our actions and thoughts are not predetermined. He bases his argument on the simple fact that the elementary stuff of which we are all made behaves randomly (Brownian movement, etc) and so nothing is predetermined.  I so agree.

Later I watched a TED talk by an enthusiastic young determinism believer. He was very convincing of course. But, at the end of his talk, he advised us that we must not use this determinism as an excuse for irresponsible action! We must, he advised us, try to do the right thing and by our actions persuade others to do so too. Silly man. If everything is predetermined there can be no persuading since that assumes the possibility of changing the future and determinism determines that the future is already determined! What do you think?
