We are conscious of only a tiny fraction of the information that our brains process in each moment.1 Although we continually notice changes in our experience — in thought, mood, perception, behavior, etc. — we are utterly unaware of the neurophysiological events that produce them. In fact, we can be very poor witnesses to experience itself. By merely glancing at your face or listening to your tone of voice, others are often more aware of your state of mind and motivations than you are.

I generally start each day with a cup of coffee or tea — sometimes two. This morning, it was coffee (two). Why not tea? I am in no position to know. I wanted coffee more than I wanted tea today, and I was free to have what I wanted. Did I consciously choose coffee over tea? No. The choice was made for me by events in my brain that I, as the conscious witness of my thoughts and actions, could not inspect or influence. Could I have “changed my mind” and switched to tea before the coffee drinker in me could get his bearings? Yes, but this impulse would also have been the product of unconscious causes. Why didn’t it arise this morning? Why might it arise in the future? I cannot know. The intention to do one thing and not another does not originate in consciousness — rather, it appears in consciousness, as does any thought or impulse that might oppose it.

The physiologist Benjamin Libet famously used EEG to show that activity in the brain’s motor cortex can be detected some 300 milliseconds before a person feels that he has decided to move.2 Another lab extended this work using functional magnetic resonance imaging (fMRI): Subjects were asked to press one of two buttons while watching a “clock” composed of a random sequence of letters appearing on a screen. They reported which letter was visible at the moment they decided to press one button or the other. The experimenters found two brain regions that contained information about which button subjects would press a full 7 to 10 seconds be

Almost all our suffering is the product of our thoughts. We spend nearly every moment of our lives lost in thought, and hostage to the character of those thoughts. You can break this spell, but it takes training just like it takes training to defend yourself against a physical assault.

Incompatible religious doctrines have Balkanised our world and these divisions have become a continuous source of bloodshed. Indeed, religion is as much a living spring of violence today as it was at any time in the past. The recent conflicts in Palestine (Jews v Muslims), the Balkans (Orthodox Serbians v Catholic Croatians; Orthodox Serbians v Bosnian and Albanian Muslims), Northern Ireland (Protestants v Catholics), Kashmir (Muslims v Hindus), Sudan (Muslims v Christians and animists), Nigeria (Muslims v Christians) and Iran and Iraq (Shia v Sunni) are merely a few cases in point. These are places where religion has been the explicit cause of millions of deaths in the past decade.

There is never a moment where I find Trump persuasive. When I look at him I see a man without any inner life. I see the most superficial person on Earth. This is a guy who has been totally hollowed out by greed and self regard and delusion. If I caught some sort of brain virus and I started talking about myself the way Trump talks about himself, I would throw myself out a fucking window. That barely overstates it. Do you remember that scene at the end of The Exorcist where the priest is driving out the devil from Linda Blair and the devil comes into him and he just hurls himself out the window to end all the madness? Well, it would be like that.
