Philosophers have debated for years whether we deliberately make each of the many decisions we make every day, or if our brain does it for us, on autopilot. Neuroscientists have shown, for example, that neurons in the brain initiate our response to various stimuli milliseconds before we’re even aware that we’re taking such an action.
This heady debate has hit a very practical road in the past decade: whether individuals who commit crimes are actually responsible for them. Lawyers have argued in court that if the brain determines the mind, then defendants may not be responsible for their transgressions.

The video is the second in a series he is putting together with director Alexis Gambis called My Mind’s Eye. (The first episode featured Ned Block on the mind-body problem.)
