Determinists who argue for their belief system are arguing not just against the freewill theists beliefs, but rather his experience of freewill.
The argument is that the free will experience we have is illusory or mistaken. IOW, however we
feel about them, the choices we make are determined by prior events (and if that wasn't the case, they'd be random).
Whether the universe is completely deterministic or not (I don't know), it seems to me that at any particular time I am the product of my genetic inheritance and its interaction with my environment over my life, i.e. my life experiences up to that point - that's what makes me who I am and determines how I feel at that point. If my choices were not determined by who I am and how I feel at that point, they wouldn't be
my choices
¯\_(ツ)_/¯
Which is why the good epistemic approach is to believe in and rest our lives on things we can immediately experience (e.g. the moral experience and the freewill experience.) Which you agree that the determinist has no other choice but to do in their daily lives, the no other choice isn’t really true though, lots of people hang onto their determinism for grim death, absolving themselves from any responsibility in the meanwhile. Others remain largely unchanged, because they’re living as if their determinism isn’t true.
You seem to have encountered very different determinists than I have.
Science (and showbiz) has shown us that to treat our immediate experiences as accurate reflections of what's happening is not a reliable epistemic approach. Not only are they unreliable epistemic guides, but our memory and recall of them is also unreliable, compounding the unreliability. But we can get by on them, they're typically 'good enough' to see us through most of the time.
As for the moral experience, if you mean our moral intuition about some situation, i.e. our conscience, then I think that's a different kind of expression, not an interpretation of how the world works, but how you feel about the world.
At least to me, determinism seems a useless piece of mental luggage to “believe in,” since it’s an idea we both affirm and deny out of different sides of our mind.
To marry up with determinism means embracing things we have to compartmentalise everyday, lest they undo the brute facts as they present themselves to us.
We do this kind of thing all the time for entertainment - we can get intense emotional stimulation and satisfaction from movies, books, stories, etc., that we know are not real, we simulate dangerous situations for the thrill, knowing they're safe (e.g. rollercoasters), we go to magic shows to be amazed and confounded by illusions we know are not real.
In the case of determinism, it's simply acknowledging that the free will we experience is another illusion. There are plenty of other everyday illusions we experience, which generally make the world seem more consistent - for example, if you touch your nose with your finger, the touch sensation on nose and finger feels simultaneous despite the nerve signals from the finger taking several times longer to reach the brain than the signals from the nose. Or when someone bounces a ball while walking away from you, the sound and the impact of ball on ground seem simultaneous until they reach a certain distance away, when they become distinctly separate, as the sound travels much more slowly than the image of the ball. In both cases, the brain 'adjusts' your perception to fit expectations, but it has its compensation limits.
The “sensible determinist” that you write about sounds like an inconsistent determinist, and the only time they ever land in the sensible category is when they stop the philosophy of determinism and embrace reality.
Not inconsistent at all. Just an acknowledgement that how we feel things are is not necessarily how they are. For some, this changes how they feel about themselves and others, for other it doesn't.
Every determinism rejects their own experience of possessing libertarian freewill, as every (philosophically) amoral child abuser rejects their moral experience. Both have rejected these bedrock experiences in light of something else, either their deterministic philosophy, or maybe their debauched lust for kids.
It's not a rejection of the experience, but an acknowledgement or realisation that the experience is an illusion.
An
amoral child abuser, by definition, doesn't have a moral experience to reject. Some people (sociopaths) are like that; they know rationally that other people think X, Y, or Z is wrong, but don't feel that themselves. Others do feel that it's wrong but feel periodically compelled to do it (perhaps akin to a compulsive addict or gambler, or someone who gets 'red mist' rages).
There’s a subcategory of people who don’t experience moral things, serial killers and the like, but they’re just handicapped. Maybe somewhere in the vast net of information online there’s evidence that determinists are likewise damaged in some way, higher on the autistic spectrum perhaps.
Determinists (the ones that are not sociopathic!) have moral experience and feel the same emotions doing what is right or wrong as everyone else, but will explain it in terms of their innate moral predispositions (sense of fairness, preference for helpful agents over unhelpful agents, etc) and their cultural upbringing.
Determinism doesn't make you some kind of amoral robot; it means you're the person you are because of your inheritance and life experiences - and new experiences can change the person you are... and if you happen to be the sort of person who wants to change, you're likely to seek out those experiences. IOW, you can live normally without accepting incoherent libertarian free will. Many accept various forms of compatibilist free will - such as accepting that the feeling of free will may be illusory, but is useful enough in practice that it doesn't matter.
You’re not understanding here. I’m writing that when people deny one thing they immediately experience, they’ve then undermined the rational warrant with which they affirm other lived experience.
Do you accept all experience without question? Do you believe that Yuri Geller can really bend spoons with his mind? Have you never had an experience you later found to be mistaken?
Determinists who deny the immediate experience of freewill wound the credibility of their other immediate experiences (e.g. the moral experience.)
No, as explained above. Accepting that your moral experience is a product of chains of events ultimately beyond your control doesn't stop you from feeling that some things are right and some things are wrong and feeling appropriate responses when you take right or wrong actions.
Denying the reality of felt objective morals can’t be done without running the risk of mutilating other felt experiences. Determinists run the same risks by rejecting the experience of freewill.
Felt morals are, by definition, subjective, whether you think there is some objective source of morals or not.
But, as I said earlier, there's a difference between accepting the felt experience itself and accepting that a felt experience represents or reflects how the world works. I would group moral experience along with other emotional experiences, as feelings that represent a state of mind, and group the experience of free will separately, as an experience that is supposedly a reflection of
how the world works.
