Reliable cause and effect in determinism is fixed cause and effect, being fixed does not equate to freedom. Just the opposite.
Question 1: Then you have a small problem to solve:
a) Shall we remove the terms "free" and "freedom" from all our dictionaries?
OR
b) Shall we define freedom in a way that does not require "freedom from causal necessity"?
As we know, freedom may be used in reference to unimpeded or unrestrained actions;
Correct.
the ball flies through the air unimpeded, the dog has been freed from its chain, planets and moons orbit freely, etc, etc.
One of those things is not like the others. The ball, the planets, and the moons, do not experience constraint. The dog experiences his chain as a constraint. For the dog, freedom is a meaningful concept, because the
chain prevents him from chasing the squirrel, something that he really
wants to do.
But relative that relative unimpeded actions do not equate to freedom of will. The dog may be free from the chain, but it isn't free from the constraint of the yard.
The dog experiences the
fence around the yard as a constraint, because the squirrel has escaped to the other side of the fence.
The planet freely orbits the sun, but it can't do anything else, it is not free to roam.
Fortunately, the planet has no desires to do anything, so being "free" of its orbit is meaningless to the planet. On the other hand, if the Earth were free of its orbit, it would be a very
meaningful event for us, because the Earth would float out into space, where things would get very cold and we'd all die. So, again, a very good argument for why reliable causation is our friend, to keep our Earth orbiting the Sun.
We can act in accordance to our 'will'' - which is determined by brain state - and the actions that follow are unimpeded, but you can't do anything else but what was determined by brain state.
Why would I want to do anything else than what my brain state chooses to do? My brain states, deciding what I will do, and my being able to do it, is what
my freedom is all about!
You act according to inner necessity. Your constraints are determined by inner necessity. You can't do otherwise. Unimpeded action is not free will.
Apparently some unimpeded actions are exactly what free will is about. One such unimpeded action is deciding for myself what I will do. And that unimpeded action is commonly called "free will", because it is literally me being
free to decide for myself what I
will do.
And if my "inner necessity" (my series of brain states) chooses to have pancakes for breakfast, even though I could have had eggs again, then why would I complain? That "inner necessity" happens to be
me, deciding to have pancakes for a change.
Now, if I started to fix pancakes, and found that the box of pancake mix was empty, then I would complain.
That would be a meaningful constraint upon my ability to do what I wanted.
So, let's summarize what just happened in terms of causal necessity:
1.
It was causally necessary from any prior point in time that I woke up hungry.
2.
It was causally necessary from any prior point in time that I checked to see what I could fix for breakfast.
3.
It was causally necessary from any prior point in time that I found eggs in the fridge, so I actually
could have fixed eggs.
4.
It was causally necessary from any prior point in time that I found pancake mix in the cupboard, so I
could also fix pancakes.
5.
It was causally necessary from any prior point in time that I recalled having had eggs for the past three days.
6.
It was causally necessary from any prior point in time that I chose to have pancakes for a change.
7.
It was causally necessary from any prior point in time that I fixed and ate the pancakes.
8.
It was causally necessary from any prior point in time that I would have two real options to choose from, pancakes and eggs.
9.
It was causally necessary from any prior point in time that No one else would be there to force me to eat the eggs.
10.
It was causally necessary from any prior point in time that I would choose to eat the pancakes of my own free will.
Now, here is my point about causal necessity. Causal necessity changes nothing. Everything happens just the way it always does, through a series of events where one thing necessarily leads, naturally and reliably, to the next thing.
So, we can simply drop that leading phrase, "It was causally necessary...", without any loss of meaning.
Causal necessity has no meaningful implications to any human scenarios. All of the useful information is from knowing the specific causes of specific effects.
Oh, and, of course,
it was causally necessary from any prior point in time that I would have two real options to choose from, pancakes and eggs. The fact that I would fix pancakes, is true. The fact that I could have fixed eggs, is equally true.
You're driving down the road with your friend, a hard determinist, sitting in the passenger seat. You see a stoplight up ahead. Right now it is red, but you don't know how long it has been red. Will the light remain red or will it turn green as you arrive? You don't know. So, as you get closer you decide to slow down, just in case it remains red. But then the light changes to green just before you arrive, so you resume speed and continue down the road.
Your friend, the hard determinist, says to you, "Why did you slow down?". You tell him, "I wasn't sure whether the light would turn green. It could have remained red." Your friend corrects you, "No, the light could not have remained red. You see, in a determined system there is only one possibility, only one thing that can happen. So, the light could not have remained red!". And then he adds, "So, why did you slow down?". How do you answer the hard determinist?
Information is being acquired via the senses as you approach the intersection, what you do is determined by your (brain) experience with traffic signals, your speed, distance from the traffic lights, an estimation of signal duration...all of which comes together to determine your actions, you stop or go based on these factors.
Or, to phrase that more concisely, you slowed down because your brain concluded that the light "could have" remained red.
After all, the brain is an information processor, evolved to respond to environmental conditions. After all, it doesn't take free will to acquire and process information and act rationally.
Another sorting problem. Here's the solution: Acquiring and processing information enables us to make rational choices. When we are allowed to make these choices for ourselves, it is called "free will". When a choice is imposed upon us against our will by someone or something else, then it is "not free will".
The brain acquires and processes information and acts accordingly in both instances. In one instance you act according to your 'will,' but through inner necessity. The other, you are being forced to act against will.
Yes. That is why we have the distinction between a freely chosen will and a coerced will. It is a significant distinction.
The references relate to in external conditions, not how thought and action is produced.
Of course. The brain is processing information about its internal and external environments and uses both when making decisions.
Being free from external necessity doesn't free you from internal necessity;
Why would you expect someone to be free from themselves? Wouldn't that literally make them someone else?
No, we don't need freedom from internal necessity. Free will itself is a form of "internal necessity", specifically by rational calculation, in which our options are weighed, according to our own beliefs and values, and the result of that evaluation necessitates our subsequent action.
Question 5: Is it possible that the Stanford Encyclopedia of Philosophy's definition of determinism is incorrect?
Why would it be? It's the basic definition of determinism, which is why they included it. Are you suggesting a better definition?
Of course. The SEP definition you're using is this one:
“Determinism: The world is governed by (or is under the sway of) determinism if and only if, given a specified way things are at a time t, the way things go thereafter is fixed as a matter of natural law.” [5] (SEP)
I would suggest this definition of determinism instead:
Determinism is a belief in causal necessity, that all events are reliably caused by prior events, such that theoretically (though not practically), given sufficient knowledge of any past state and its events, we could predict with 100% accuracy, any future state and its events.
Note that I've omitted the witchcraft and superstition contained in the SEP's definition, specifically the "governing" and the "swaying". Determinism is not an active force. And the author of the
SEP article on Causal Determinism, Carl Hoefer, points this out himself later in section 2.4 Laws of Nature:
"In the physical sciences, the assumption that there are fundamental, exceptionless laws of nature, and that they have some strong sort of modal force, usually goes unquestioned. Indeed, talk of laws “governing” and so on is so commonplace that it takes an effort of will to see it as metaphorical." (italics mine)
We speak from our limited perspective of the world, its changing states and conditions. Our perception of 'possible outcomes' is a reflection of limited information. The world is too vast and complex for us to make anything approaching detailed predictions of future events, just projections of trends, which may or may not persist.
Exactly. When we cannot speak with certainty as to what "will" happen, we imagine what "can" happen, in order to deal more effectively with what actually "does" happen.
There are many "possible" futures, but only one "actual" future. There are many things that "can" happen, but only one thing that "will" happen.
Within the domain of human influence (things we can make happen if we choose to), the single actual future will be chosen by us from among the many possible futures that we will imagine.
