A few months ago I picked up an issue of Time Magazine titled ‘Your Brain: A User’s Guide’. One of the articles was called ‘The Riddle of Knowing You’re Here’, by Steven Pinker. It was really interesting but I couldn’t find it online, so I’ll cite the relevant portions of it here as well as talk about possible implications. As the author points out, “The major religions locate [consciousness] in a soul that survives the body’s death to receive its just reward or punishment or to meld into a global mind. For each of us, consciousness is life itself”. The article goes on to explain the two problems that scientists encounter about consciousness. These problems were dubbed by the philosopher David Chalmers as the Easy Problem and the Hard Problem.
“What exactly is the Easy Problem? It’s the one that Freud made famous, the difference between conscious and unconscious thoughts. Some kinds of information in the brain-such as the surfaces in front of you, your plans for the day, your pleasures and peeves-are conscious. You can ponder them, discuss them and let them guide your behavior. Other kinds-like the control of your heart rate, the rules that order the words as you speak and the sequence of muscle contractions that allows you to hold a pencil are unconscious. They must be in the brain somewhere because you couldn’t walk and talk and see without them, but they are sealed off from your planning and reasoning circuits. The Easy Problem, then, is to distinguish conscious from unconscious mental computation, identify the proper correlates in the brain and explain why they evolved.
The Hard Problem, on the other hand, is why it feels like something to have a conscious process going on in one’s head - why there is first-person, subjective experience. Not only does a green thing appear different from a red thing, remind us of other green things and inspire us to say, ‘That’s green’ (the Easy Problem), but it also actually looks green, it produces an experience of sheer greenness that isn’t reducible to anything else. As Louis Armstrong said in response to a request to define jazz, ‘When you got to ask what it is, you never get to know.’ The hard problem is explaining how subjective experience arises from neural computation. The problem is hard because no one knows what a solution might look like or even whether it is a genuine scientific problem in the first place. And not surprisingly, everyone agrees that the Hard Problem (if it is a problem) remains largely a mystery.
Although neither the Hard nor the Easy Problem has been solved, neuroscientists agree on many features of both of them, and the feature they find least controversial is the one that many people outside the field find the most shocking. Francis Crick called it ‘the astonishing hypotheseis’ - the idea that our thoughts, sensations, joys and aches consist entirely of physiological activity in the tissues of the brain. Consciousness does not reside in an ethereal soul that uses the brain like a PDA; consciousness is the activity of the brain. ...And when the physiological activity of the brain ceases, as far as anyone can tell, the person’s consciousness goes out of existence. ...Another startling conclusion from the science of consciousness is that the intuitive feeling we have that there’s an executive ‘I‘ that sits in a control room of our brain, scanning the screens of the senses and pushing the buttons of the muscles, is an illusion. Consciousness turns out to consist of a maelstrom of events distributed across the brain. These events compete for attention, and as one process outshouts the others, the brain rationalizes the outcome after the fact and concocts the impression that a single self was in charge all along. The illusion of voluntary actions is in part a result of noticing a correlation between what we decide and how our bodies move.”
So, if we’re not the decision-maker, then who are we? If nobody has a say in their own thoughts or actions, then how should that affect the way that we treat other people? How should it affect the way that we treat ourselves? This doesn’t seem to leave any room for pride or condemnation. Obviously we need to keep dangerous people away from the populace, but we don’t need to kill them, or spend our time hating them. Like the Buddha said, “Holding on to anger is like grasping a hot coal with the intent of throwing it at someone else; you are the one who gets burned.”
