The very essence of determinism entails 'could not have done otherwise.'
That is what many people have traditionally claimed to be the essence of determinism. But it is a false claim, as we've demonstrated.
Demonstrated? Hardly. It has been claimed and asserted, and falsified with the given terms and conditions of 'fixed' and 'no deviation.'
The "very essence" of determinism is actually causal necessity. Causal necessity is logically derived from simple cause and effect. If A causes B, and B causes C, then, if A happens both B and C will necessarily happen.
Right, only what is done, what must happen - which excludes 'could have done' as an element of the system.
So, did A "cause" C? No, not directly. B is the direct cause of C. This distinction is necessary if the notion of causation is to be intelligible. For example, did the Big Bang "cause" me to choose the salad instead of the steak for dinner? Of course not. It was the bacon and eggs I had for breakfast, and the double cheeseburger I had for lunch, and my desire to eat more fruits and vegetables that caused me to choose the salad instead of the steak for dinner. These concerns that caused my choice, were my own concerns.
There is no separation between A, B or C. As the system evolves from prior to current and future states, they are absolutely related.
Not only is C entailed in A, so is D, E, F, G, right through till the whole shebang runs down.
''All of these events, including my choices, were causally necessary from any prior point in time. And they all proceeded without deviation from the Big Bang to this moment.'' - Marvin Edwards.
Where the big bang is A -time t - the evolution of the system is entailed in the initial conditions and the way things go ever after fixed by 'natural law.'
The Big Bang had no interest in what I would order for dinner. To suggest it "caused" me to order the salad instead of the steak is nonsense.
Initial conditions and the way things evolve ever after;
''All of these events, including my choices, were causally necessary from any prior point in time. And they all proceeded without deviation from the Big Bang to this moment.'' - Marvin Edwards.
What Does Deterministic System Mean?
''A deterministic system is a system in which a given initial state or condition will always produce the same results. There is no randomness or variation in the ways that inputs get delivered as outputs.''
I could have chosen the steak, but I wouldn't have chosen it under those circumstances. The fact that I would not order the steak never implies that I could not order the steak.
It's pointless saying 'I could have' when the circumstance can never be different to what they must necessarily be.
It serves no purpose to say it. It cannot change anything. It can't be used as an argument for free will.
In fact, if I had cantaloupe for breakfast and a salad for lunch, then I definitely would have ordered the steak for dinner.
You see, no matter what I actually ordered, I always had the ability to order the steak, thus it was truly something that I could have done.
Not possible. If it was, it would be a deviation, an action that was not determined. We are talking about determinism, not 'could have' or might have' or ''if things had been different.'
Fixed by antecedents entails 'could not have done otherwise.'
I'm afraid not. Fixed by antecedents entails only that we "would not have done otherwise, even though we could".
Just a softer way of saying 'could not have done otherwise' - which changes nothing, serves no purpose and does not help in the argument for compatibilism.
Determinism and not determinism is a contradiction.
Exactly. So stop drawing false implications and let determinism simply be determinism, the reasonable belief that all events are reliably caused by preceding events. And stop pretending that we are not among the events that reliably cause future events.
The remark 'could have' gives the impression of a possibility of an alternate choice where none exists. It is a false impression.
I was physically and mentally able to order the steak. So, "I could have order the steak" was literally true.
If the events of the world are determined, you were not only physically and mentally able to order the steak, you inevitably ordered the steak. You could not have done anything other than order the steak. Your action of ordering the steak proceeded as it must, freely and without restriction, precisely as determined.
''Wanting to do X is fully determined by these prior causes. Now that the desire to do X is being felt, there are no other constraints that keep the person from doing what he wants, namely X.'' - cold comfort in compatibilism.
“It might be true that you would have done otherwise if you had wanted, though it is determined that you did not, in fact, want otherwise.” - Robert Kane
