Consciousness … what is it good for?

What’s the point of consciousness? David Barash, an evolutionary biologist and “aspiring Buddhist,” suggests that the evolutionary advantage of consciousness “includes our efforts to interpret what other individuals are doing, feeling and thinking, as well as how those others are likely to perceive us in return.” How far is this from Nietzsche’s hypothesis that consciousness is not a self-contained sphere of individuality but is instead a net of communication among individuals?

We are puppets … but are we free or not?

Sam Harris and Daniel Dennett are determinists who agree that our thoughts and acts are completely determined by prior states of the universe and the laws of nature. But Harris is a hard determinist who thinks free will is simply an illusion while Dennett is a compatibilist who thinks we do have free will even though we are determined. In a review of Harris’ Free Will, Dennett says the book is veritable museum of mistakes. Harris replies with a lament that Dennett’s review is “a strange document—avuncular in places, but more generally sneering” and is itself a collection of distortions and mistakes. The review and reply are both lengthy, but a fairly quick look will give the student an idea of the differences between hard determinism and compatibilism.

It it the brain that makes humans unique?

What makes you so special? The brain probably has something to do with it. But what exactly? “If it seems like scientists trying to find the basis of human uniqueness in the brain are looking for a neural needle in a haystack, it’s because they are. Whatever makes us different is built on the bedrock of a billion years of common ancestry. Humans will never abandon the quest to prove that they are special. But nor can we escape the fact that our minds are a modest tweak on an ancient plan that originated millions of years before we came onto the scene.”

Was it immoral to watch the Super Bowl?

Are football fans complicit in the brain damage and other injuries players suffer? Steve Almond worries that he and other fans are: “[M]edical research has confirmed that football can cause catastrophic brain injury — not as a rare and unintended consequence, but as a routine byproduct of how the game is played. That puts us fans in a morally queasy position. We not only tolerate this brutality. We sponsor it, just by watching at home. We’re the reason the N.F.L. will earn $5 billion in television revenue alone next year, three times as much as its runner-up, Major League Baseball.”
