The fact that an event is deterministically entailed means that it actually will happen, exactly as it does happen, without deviation.
Choosing will happen. And there will be two or more real options that we are really able to choose. The fact that we do not choose an option does not imply that we were ever unable to choose it, but only that we would not choose it.
The logic goes astray when you label what is a process of determinism 'choosing.'
If we are to distinguish one deterministic process from another, we must give them different names. Addition, subtraction, and choosing are three distinct deterministic processes. Each of them executes according to their own unique logic. If we fail to label them correctly, then we may find ourselves performing subtraction when we need to perform addition, or performing choosing when we need to perform subtraction.
So, labeling deterministic processes is essential to knowing what we're doing.
Without alternatives, there is no choice.
Correct, and there will always be at least two alternatives. In fact, our encountering multiple alternatives causally necessitates the choosing process! So, we can always count on there being alternatives to choose from.
Whatever happens must necessarily happen.
Always.
According to your own descriptions, there is no possibility of doing otherwise.
Not according to my descriptions. You must be talking about that other guy, DBT.
According to my description, determinism guarantees that there will be multiple possibilities whenever a choosing process begins, just like determinism guarantees that there will be multiple numbers whenever an adding process begins. Both are part of the inevitable unfolding of events, that will proceed without deviation.
If it is determined that you brush your teeth at 6am, you must necessarily brush your teeth at 6am, and you cannot choose a different action at 6am. Nothing else can happen.
You are confusing what "can" happen with what "will" happen, and ending up with false statements.
The true statement reads like this:
"If it is determined that you brush your teeth at 6am, you must necessarily brush your teeth at 6am, and you
will not choose a different action at 6am. Nothing else
will happen."
Getting this right takes some practice.
Determinism fixes all action.
Well, technically, determinism does not actually do or fix anything. All of the doing and the fixing is being done by the actual objects that make up the physical universe and the actual forces between them. It is the natural interactions between these objects that bring about all events.
I make this point to remind us all that we happen to be one of those objects. And, being members of an intelligent species, we go about in the world causing events to happen, and doing so for our own goals and reasons. Hard determinists often attempt to hide this detail in the more general notion of "determinism".
Fixed actions are not a matter of choice because there are no alternatives.
When it is fixed that choosing will happen, then it necessarily will happen, and it will also be fixed that two or more alternatives will show up before the choosing begins.
There is no alternative to there being multiple alternatives, because that is exactly how the events were always going to unfold. Just so, and in no other way.
''
Determinism entails that, in a situation in which a person makes a certain decision or performs a certain action, it is impossible that he or she
could have made any other decision or performed any other action. In other words, it is never true that people
could have decided or acted otherwise than they actually did.''
Same false statements created by confusing what "can" happen with what "will" happen.
The true statements are these:
"Determinism entails that, in a situation in which a person makes a certain decision or performs a certain action, it is impossible that he or she
would have made any other decision or performed any other action. In other words, it is never true that people
would have decided or acted otherwise than they actually did."
Whenever a decision must be made, there will be at least
two things that we
can choose, even though there is only
one thing that we
will choose. Because there are always two things that we can choose, at the end of our choosing there will always be the single thing that we will choose and
at least one other thing that we
could have chosen, but didn't.
Thus, as commonly understood, "I chose the Salad, even though I could have chosen the Steak", is true in both its parts.
The process began long before it comes to you knowing the sum. You inevitably come to the sum as the system evolves. It is not possible to come to the sum/answer without the prior states of the system that inexorably brings you to the point where you need to calculate and produce an answer for whatever problem you need to solve.
And with choosing, the prior states of the system inexorably bring me to the point where I have two alternatives, and I must make a choice before I can continue. And I will make the inevitable choice according to my own goals and reasons as they inexorably are at that point in time. Because that is who I inexorably will be. And, if it is inexorably fixed that I will be free of coercion and undue influence, then that will inexorably be a choice of my own free will.
Determinism, causal necessity/inevitability, the inexorability of it all,
changes nothing.
