Brain surgery Quote by Stephen Hawking
““Recent experiments in neuroscience support the view that it is our physical brain, following the known laws of science, that determines our actions, and not some agency that exists outside those laws. For example, a study of patients undergoing awake brain surgery found that by electrically stimulating the appropriate regions of the brain, one could create in the patient the desire to move the hand, arm or foot, or to move the lips and talk. It is hard to imagine how free will can operate if our behaviour is determined by physical law, so it seems that we are no more than biological machines and that free will is just an illusion.””

![“[Research] suggests that what we think of as free will is largely an illusion: much of the time, we are simply operating on automatic pilot, and the way we think and act – and how well we think and act on the spur of the moment – are a lot more susceptible to outside influences than we realize.” quote by Malcolm Gladwell](https://sms4smile.com/quotes/img-quotes/8f7/malcolm-gladwell-348_free-will_research-suggests-that-what-we-think-of_133351.jpg)
