What is the essence of the agent "I" to which we refer when we say things like "I want to go to the movies", "I will have two eggs for breakfast", "I have free will", or even "I love you"? This "I" to which I refer is the essence of me, it is the source of my will.
My "I" at the present time clearly has much to do with a particular neurophysiological and physical arrangement/pattern/combination of chemicals in my body, which (for brevity) I shall hereafter refer to as my "present neurophysiological state" or PNS. I will even accept (allowing for something possibly non-physical or spiritual or ephemeral in our being) that my PNS MAY also include something called the "soul" (whatever that may be). By definition, then, the PNS includes within itself ALL causative influences (including brain states that we call memories and experiences) which may in any way affect my present or future desires, wishes, choices or actions (hereafter my "choices").
I can therefore in principle characterise my feeling of "I" by specifying precisely my PNS. (Of course, complete characterisation of the PNS may be impossible in practice, but we are talking of things in principle here).
It is important at this point to understand that in my characterisation of the PNS I am NOT making any assumptions about determinism (ie I am not assuming that the universe is necessarilly wholly deterministic). Whilst the PNS may be a source of causative influences, I am not saying that everything I do can be traced back through a fully deterministic causal chain originating in my PNS.
Some of my present and future choices are thus in some way dependent on my PNS. We can say that my PNS is a cause, or a source, of my present and future choices. However, my PNS does NOT necessarily fully determine my present and future choices, because there may be additional causal influences outside of my PNS which also impact those choices. Hence, my PNS is a PART OF the determining factor for my present and future choices, but it may be the case that it is not the ONLY determining factor. To be correct, therefore, we should say that our present and future choices are dependent on the COMBINATION of PNS and external causative factors.
To signify that we consider our PNS is in some way responsible for determining our present and future choices, we often say that such present and future choices are NOT WHOLLY CONSTRAINED by external (present and future) causative factors.
Given that we can specify precisely (in principle) the PNS, we can therefore also specify precisely (in principle) some of the causal sources of our present and future choices.
The question now is : Does the PNS necessarily have anything to do with any antecedent states or antecedent history or antecedent causative influences (hereafter : "antecedent states") OVER AND ABOVE the full specification of the PNS? Remember that the PNS is supposed to be the full characterisation of "I" at the present time, INCLUDING possible causative influences of present and future choices (which implicitly also includes particular brain states that we call our memories and experiences). In other words, having specified precisely a particular PNS, does it matter (does it make any difference to the PNS) what the antecedent states of that PNS are/were?
Clearly, if the PNS is the sum total of the "I" in the present time (which includes within itself all the brain states that we call memories and eperiences) then the antecedent states have no other (additional) effect on the PNS.
In other words, (and this is the key issue) a particular PNS contains the complete specificiation of my present "I", and it could (in principle) arise either spontaneously with no antecedent state, or it could arise from a random antecedent state, or it could arise from a purely deterministic antecedent state - what matters is ONLY the PNS, not HOW the PNS was created.
My PNS is my source of will. It does not matter one iota whether I truly existed prior to this present moment; I could in principle have been created ex nihilo by some divine entity just moments ago; I could have spontaneously assembled by pure chance from indeterministic causes; or I could be part of a completely deterministic machine which can trace back precise chains of deterministic cause and effect to the Big Bang; none of this matters as far as my source of will, my "I", is concerned. The ONLY thing that matters is my PNS, and NOT from whence it came.
Where Libertarians (and others who seek some non-deterministic "source" of "free will") seem to go wrong is that their argument carries with it the implicit assumption that our present and future choices are somehow NOT determined solely by a combination of our PNS and external causative factors, but are instead determined by "something else". Why do I say this? Because Libertarians insist that there must be some non-deterministic source of our choices (and it is supposed to be this non-deterministic source which then renders these as "free will" choices). In other words, according to the Libertarian philosophy, our choices are NOT determined solely by a combination of our PNS and external causative factors, there is "something else" that causes them.
The problem is that the Libertarian has no idea what this "something else" might be. He/she perhaps feels intuitively that the PNS cannot be the result of wholly deterministic antecedent states, and yet he/she cannot get away from the fact (as we have shown above) that the only important fact is the characterisation of the PNS, and NOT from whence the PNS arose. Postulating some kind of indeterminate antecedent states for the PNS changes absolutely nothing - the PNS IS what it IS, regardless of how it arose, and the PNS (combined with external causative factors) determines our present and future choices. The Libertarian would seem not to accept this view, but he/she would seem to want to postulate "some mysterious something else" over and above the PNS, from which our "free will" choices somehow arise. The Libertarian cannot tell us what this "mysterious something else" is, but it certainly has nothing to do with indeterminism.
