Metaphysical
libertarian freedom
Do we have freedom of the will? That is,
do we have what philosophers call metaphysical libertarian freedom (not to be
confused with political libertarianism)? Or are our decisions and actions
wholly determined by causes arising from our biological-chemical-genetic nature
coupled with the nurture of social environment? My answer: people have metaphysical
libertarian freedom (MLF), at least to some significant extent.
Today I will make a secular
philosophical case for MLF (next time I'll provide a theological case). I'll define
MLF, then contrast it with determinism, then set out four brief arguments—a
cumulative case argument—for MLF.
MLF means that I am an intelligent
causal agent. On this view, the cause of my action originates with, i.e., is
produced and initiated by, me. Whether a particular action occurs is up to me. I have the power to do
otherwise. Philosopher Robert P. George characterizes MLF as "the power of
an agent to cause what the agent is not caused to cause."
In contrast, determinism says all my
desires and choices to act are effects wholly necessitated (as opposed to
merely influenced) by a set of preceding causes. On this view,
"freedom" means merely that our actions result unhindered from our
wants and desires, which are wholly caused by nature and nurture. Theoretically,
I could do otherwise, if I wanted to. But my wants are wholly determined and
are what they are, and I must dance to their tune. So, in fact, I couldn't do
otherwise.
Why believe MLF? Here are four
arguments.
1. Our intuition that we are sometimes free agents counts in favour of MLF.
My raw non-inferential experience in everyday life is such that I sometimes do
in fact initiate an action.
Try this simple experiment. Hold out
your index finger. Now realize that you can move your finger either to the
right, to the left, up, or down. Now move it in one of these directions. The
movement of your finger one way or the other is up to you. And you intuit—know—this.
But isn't it possible that the intuition
is illusory? Maybe there are unnoticed causes at work?
Reply: Yes, it's possible. We can
imagine that the intuition is illusory. But keep in mind that mere possibility
is not plausibility and that to imagine a doubt is not to really doubt. Also,
there are more arguments.
2. Our experience of deliberation counts in favour of MLF,
too. Goal-oriented contemplation concerning which of two (or more) future
courses of action we should choose makes good sense on the assumption that
doing alternative A and doing alternative B are each within my power to do. I
can weigh pros and cons—and still pick either alternative.
Philosopher Richard Taylor observes,
"I deliberate in order to decide
what to do, not to discover what it is that I am going to do."
3. The reality of moral judgment and moral
obligation also counts in favour of MLF.
Philosopher Peter van Inwagen: "The
judgment that [morally] you shouldn't have done X implies that you should have
done something else instead; that you should have done something else instead
implies that there was something else for you to do; that there was something
else for you to do implies that you could have done something else; that you
could have done something else implies that you have [metaphysical libertarian]
free will."
Philosopher Lois Hope Walker adds:
"It simply makes no sense to say that I have an obligation to do something
that I do not have the power to do."
4. Lastly, if MLF is false, then you are
a robot (determined) or a mere spasm (undetermined/ random). But you know you
are neither.
Thus, we have good reasons for thinking metaphysical
libertarian freedom is true.
In a world generally governed by laws of
nature, we are odd and mysterious creatures. Nonetheless, wisdom calls us to choose (and live in accordance with)
life, truth, goodness, and beauty.
