Over the years many different Objectivists have said much about free will; most notably the original, herself. But the subject has been recurring rather frequently and I, for one, think a thorough reexamination and (more importantly) concretization is in order.
To start things off, the root of the problem [for average laymen] seems to stem from two seemingly contradictory principles:
1; Volition is axiomatic
The fact that everyone who reads this sentence has the choice to read it or not, as they wish, is self evident to them.
Volition itself is introspectively apparent, indisputable and irreducible (at least as far as I can tell); I’m fairly sure it’s axiomatic but we’ll return to the implications shortly.
2: Every thing is ultimately necessary
By this I mean that nothing is causeless. There is a reason for the existence and actions of every entity and, given enough knowledge, every entity’s future actions could be predicted. In the words of Peikoff:
“No other universe is possible or imaginable [given sufficient information]”; one could imagine flying through the sky like superman but, if one bears the law of gravity in mind, one knows it isn’t possible.
This principle of necessity is, I think, not only an explicit part of Objectivism; it’s implicit in all rational thought whatsoever. The alternative is for things to act randomly and, if that were ever truly accepted, no inquiry of any sort would be possible; even superstition would be too specific of a confinement (and without knowledge, no action or life would be possible).
So we have 1: the axiom of volition and 2: the principle of necessity (corollary of identity)
I use necessity because the meaning of causality has been somewhat obscured, but that’s essentially what I mean.
The problem arises when we apply necessity to volition, because we end up debating either Volition by analyzing whether choice is REALLY possible or Necessity by analyzing whether every effect must REALLY have a cause.
I think that both principles are valid and accurate; I think the thing to reexamine is their derivative implications, specifically regarding each other, which thus far have been taken for granted [by average laymen].
Regarding necessity, we have a habit of assigning ONE cause to ONE effect. I’m not sure where it stems from but it obviously doesn’t conform to reality and, consequently, I’d like everyone to bear in mind that multiple interacting entities usually produce multiple effects, in nature.
For example: were you caused by your mother, your father or an oxygenated atmosphere? That’s what I mean; let’s avoid it.
Regarding volition, the implicit fallacy is in a widespread misintegration of the concept “possible” which is taken to mean causeless; a negation of necessity (which is what makes the two seem contradictory).
But do human beings actually behave arbitrarily?
I think that all of my own choices, including the choice to write this presently, are determined in a singularly necessary way: MY CHOICES ARE DETERMINED BY MY THOUGHTS.
Sorry if that’s a non sequiter at present but I have to go.
That is, in a nutshell, what I’ve surmised about Objectivism’s take on volition and why I think that free will is absolutely compatible with determinism: you make every decision for your own specific reasons and your ultimate fate depends on those decisions.
