Whenever the hard determinist view is brought up in online discussions there is almost always someone that says no free will or genuine moral responsibility logically entails fatalism and nihilism. If everything that happens couldn’t help but happen and people’s choices aren’t truly free then somehow life is meaningless and morality doesn’t exist.
What is your opinion on this common claim in response to hard determinism?
My opinion is that it’s completely wrong and a fundamental misunderstanding of the matter. In reference to fatalism people still have desires to do and experience things and your choices still matter in a practical sense. People still have to do things for things to happen. Very few people would be content or able to lay in bed and stare at a ceiling their entire life because their choices are technically predetermined going back to the beginning of the universe. Choosing not to do anything out of fatalism is still a choice and a very miserable one.
In reference to nihilism I think meaning and morality aren’t dependent on hard determinism being true or false. Things still have meaning and value to people if only in a practical sense even if there was no other way for things to happen and you couldn’t possibly make choices other than the choices you made. Depending on your philosophical views this is likely the most contentious part but I think people would and can still have value and rights that shouldn’t be violated with or without determinism being true. Objective rights and value may not exist in a tangible, scientifically provable sense but that doesn’t mean they don’t exist at all. Pain and pleasure are still very much real things whether they’re determined to happen or not. Whether or not someone like Hitler, Osama, El Chapo Bundy had ultimate control over their choices doesn’t make them any less morally abhorrent or their actions any less evil or harmful. As hotly contested as the topic is I can’t recall a philosopher ever using the deterministic nature of the universe as evidence that good and evil don’t exist and the lives of sentient beings have no actual value.
