1. “Greg Graffin: As for free will, whatever it is, we can agree that it’s a feeling that is explained by an idea. That idea is a meme and it requires an explanation. The intellectual justification for free will used to come from theology. Science hasn’t begun to think about free will in enough detail, but when scientists talk about it, it’s clear they are trying to justify us having it, so it’s another kind of justification for a particular idea: the meme of free will. The human desire to explain the feeling of free will probably comes from some other psychological phenomenon that has little to do with whether we actually have any mental abilities that aren’t caused by a complicated set of stimuli. It’s best to assume that we don’t have free will, and that it hasn’t contributed at all to any increase in human fitness. After all, humans probably increased in population size because of our propensity to follow the rules (think within the constraints of your society) rather than break them by exercising any kind of free will!”
