I was going to post some of this in another thread, but I decided not to steer that one off topic and instead create a new one.
I think free will is basically an incoherent concept. Our actions are the direct consequence our beliefs, our feelings, and our perceptions, all of which we have no conscious choice in forming. Every belief, every feeling, every perception you get is because matter and energy moved around in a certain way to cause your brain to be in the state that it is in. And if our actions are not based on our beliefs, our feelings, and our perceptions, what else could they be based on?
Either our choices have identifiable causes in the real world, or else they must be random (or at least probabilistic). Actually, I think our choices are mostly caused and only random to a very small degree. We have to take into account that quantum randomness exists, and we can make decisions based on that quantum randomness, for example with random number generators that use the decay of radioactive isotopes. But randomness doesn't give us free will. And besides the quantum randomness, the universe is deterministic. If it were not for quantum randomness, the current state of the universe would be directly predictable from the starting conditions of the Big Bang.
I don't see the lack of free will as a bad thing at all, since the randomness of the universe has almost no effect on our decisions. After all, wouldn't you rather perform actions based on objective factors like your beliefs and your perceptions than to act in an unpredictable manner or a probabilistic manner? We should be happy that we don't have free will. The fact that our actions are causally linked to the real world is what makes us capable of acting rationally. Remember, pleasure does not come from making unpredictable, uncaused decisions. Pleasure comes from fulfilling our desires, and that is best accomplished if our decisions are rational and deterministic, not random or probabilistic.
We don't need to justify the pursuit of pleasure; it is something that's built into all of our genes. It's part of our nature that we cannot and will not avoid. We can all agree to cooperate in the pursuit of pleasure and the avoidance of displeasure. And that's why it's justified to hold people responsible for their actions, even though they were deterministically destined to do what they did. Some kind of justice system is a perfectly rational way to form a society where the collective pleasure is maximized and the collective displeasure minimized.
But once we realize that free will is an illusion, this I think gives us more compassion for those who have done wrong. We know that, were we in their situation with their genetic makeup and their beliefs and so forth, we would have done the exact same thing. This should give us more of an incentive to try to rehabilitate people who are prone to do immoral things, and to create a social atmosphere where immoral actions are less likely to occur in the first place, instead of focusing on angry revenge like I think a lot of religious groups do.
Any thoughts?
