Action Quote by Stephen Hawking
“If there really is a complete unified theory that governs everything, it presumably also determines your actions. But it does so in a way that is impossible to calculate for an organism that is as complicated as a human being. The reason we say that humans have free will is because we can't predict what they will do.”
About This Quote

In simple terms: Complex laws hide predictability, creating a sense of free will.

![“[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)
