Neuroscience and Free Will

We have free will. We make our own deci­sions. We have long tak­en these basic assump­tions for grant­ed. But what does neu­ro­science make of this? In this excerpt from the BBC Hori­zon spe­cial, “The Secret You,” Mar­cus Du Sautoy (Oxford Uni­ver­si­ty) par­tic­i­pates in a brain imag­ing exper­i­ment con­duct­ed by John-Dylan Haynes, a neu­ro­sci­en­tist based in Berlin. And the results? Well, they force us to rethink things a bit. Good­bye Descartes. Good­bye mind before mat­ter. Good­bye to con­scious­ness and free will, as we tra­di­tion­al­ly like to think about them. And wel­come to the world of neu­rons, to brain activ­i­ty that makes your deci­sions before your con­scious self is even aware of them. To delve deep­er into all of this, you can watch Haynes give a 90 minute lec­ture here called “Uncon­scious deter­mi­nants of free deci­sions in the human brain.”
