1. Here are some things that are widely believed about free will and determinism.
(1) Free will is prima facie incompatible with determinism.
(2) The incompatibility is logical or at least conceptual or a priori.
(3) A compatibilist needs to explain how free will can co-exist with determinism, paradigmatically by offering an analysis of ‘free’ action that is demonstrably compatible with determinism. (Here is the late Roderick Chisholm, in defense of irreducible or libertarian agent-causation: ‘Now if you can analyze such statements as “Jones killed his uncle” into event-causation statements, then you may have earned the right to make jokes about the agent as cause. But if you haven’t done this, and if all the same you do believe such things as that I raised my arm and that Jolns [sic] killed his uncle, and if moreover you still think it’s a joke to talk about the agent as cause, then, I’m afraid, the joke is entirely on you.’<1>)And listen to Laura Waddell Ekstrom on the burden of proof:(4) Free will is not impugned by quantum indeterminism, at least not in the same decisive way that it is impugned by determinism. To reconcile free will with quantum indeterminism takes work, but the work comes under the heading of metaphysical business-as-usual; to reconcile free will with determinism requires a conceptual breakthrough.
…in the absence of an argument to the contrary, it is straightforwardly clear to most all of us as we adopt the practical deliberative point of view toward our own future that the following is true: I am free in what I do at the next moment only if I am not necessitated to do just what I do by the past and the natural laws…. The compatibilist, then, needs a positive argument in favor of the compatibility thesis.<2>
What is interesting is that each of these claims
is tacitly granted by many free-will compatibilists as well as (obviously)
by incompatibilists. The compatibilists take up the burden and labor
to overcome the supposed conceptual obstacles.
I maintain that (1), (2) and (3) are just false.
I believe (4) is false as well--though perhaps not just false.
It’s actually worse than that. Here is a confession:
I have always been free-will-blind. I don’t get it. I don’t
see what the big problem is supposed to be. (My talk today may have
the unintended effect of persuading some of you that that’s right: that
I just don’t get it.) I am a natural-born, cradle compatibilist.
Ted Honderich suggests<3> that even if we are Soft Determinists,
each of us still desires a measure of libertarian agent-causation,
or can easily be made to; the real problem is attitudinal. But if
I have such a desire, it operates at a level deeper than introspection
can penetrate.
Of course I know that there are serious arguments
for incompatibilism. Some are simple, some more complicated, some
very complicated and ingenious. But I have never found any of them
at all convincing. My purpose in this paper is to try to show that
that response is right and proper, and that there are good general dialectical
reasons for rejecting all incompatibilist arguments. (To my title
I might have added the subtitle, ‘in which it is shown that compatibilism
is not only true, but the only position rationally available to impartial
observers of the issue.’)
Ground rules: For the sake of argument, I
shall assume that determinism is true. I myself believe that it is
not true; but let us assume it, because my main thesis is the compatibility
of freedom with determinism, and because if I am right in rejecting
(4), indeterminism would not help anyway. Also, if no incompatibilist
argument succeeds, there is no reason to think that indeterminism would
make us any freer.
By ‘free’ I shall mean free in whatever sense is
germane to moral responsibility, that is, such that one is morally responsible
for only those of one’s actions that were free actions. (I know this
usage is not inevitable.<4>)
2. I begin with a general methodological
point about modality: Compatibilism, not just about free will but
generally, on any topic, is the default. For any modal claim to the
effect that some statement is a necessary truth, I would say that the burden
of proof is on the claim’s proponent. A theorist who maintains of
something that is not obviously impossible that nonetheless that thing
is impossible owes us an argument. And since entailment claims
are claims of necessity and impossibility, the same applies to them.
Anyone who insists that a sentence S1 entails another sentence S2 must
defend that thesis if it is controversial. If I tell you that ‘Pigs
have wings’ entails ‘It snows every day in Chapel Hill,’ you need not scramble
to show how there might be a world in which the first was true but the
second false; rather, you would rightly demand that I display the alleged
modal connection. And of course the same goes for claims of incompatibility.
The point is underscored, I think, if we understand
necessity as truth in all possible worlds. The proponent of a necessity,
impossibility, entailment or incompatibility claim is saying that in
no possible world whatever does it occur that so-and-so. That
is a universal quantification. Given the richness and incredible
variety of the pluriverse, such a statement cannot be accepted without
argument save for the case of basic logical intuitions that virtually everyone
shares.
3. Let us turn specifically to (1) and
(2). The second thing to notice here is that ‘incompatible’ cannot
mean, logically incompatible. No one can start with determinism
and derive in the predicate calculus any reasonable translation of the
denial that anyone’s action is ever free. What ‘incompatible’ must
mean is, jointly incompatible with some further principle. I have
argued elsewhere<5> that such a further principle is likely to
be speculative and suspiciously philosophical, and I shall develop that
point below.
The principle cannot be just the truth-functional
conditional from determinism to the negation of free will or vice versa,
because the incompatibilist is saying more than that determinism and free
will do not in fact both obtain. The principle must be independently
motivated and entail that they do not both obtain. I shall argue
below that any such principle will be dubious.<6>
Not so fast, though. It is not quite so obvious
that ‘incompatible’ cannot mean logical incompatibility. In response
to my previous work aforementioned, James Tomberlin has made a clever and
doughty move.<7> Taking my allusion to the predicate calculus
at face value, he pointed out that there are richer logics, notably modal
logics, which reveal more logical incompatibilities than can be demonstrated
in predicate logic. [box]P & ~P, [diamond]P
& [box]~P, and P & ~[diamond]P are all
logical contradictions within the meaning of the act even though they cannot
even be directly formulated in the predicate calculus. (Of course
they can be translated into the predicate calculus by appeal to
an ontology of possible worlds, and in that derivative sense shown valid
by use of predicate logic.) Thus, for all I have shown, it is possible
that determinism and freedom can be formulated in such a way that they
prove to be logically, because modal-logically, incompatible after all,
and no extraneous principle, dubious or not, will be needed.
Here, in brief, is how Tomberlin’s argument goes
(pp. 128-130). He assumes for reductio that ‘Although Bob
did A freely, his doing A has a determining cause [C].’ He gradually translates
that assumption into the vernacular of possible worlds, and proceeds to
derive both ‘[F]or any possible world, if C obtains, Bob does A [in that
world]’ and ‘[T]here is some physically possible world such that although
C obtains, Bob does not do A,’ which predicate-calculus contradiction reduces
the original assumption to absurdity. The derivation proceeds, concessively,
through a premise corresponding to the traditional compatibilist hypothetical
analysis of ‘could have done otherwise,’ though that premise is not itself
translated into possible-worlds talk So Tomberlin’s thesis is that
even if that ostensible pillar of compatibilism is granted, the original
assumption is still refuted via the predicate calculus and incompatibilism
is thus established.
The trouble with Tomberlin’s argument, I have argued
elsewhere,<8> is that although each of its premises is perfectly
true and one might casually think that the conclusion follows from them,
the tendentiousness lurks in the untranslated premise, which reads: ‘In
C Bob could have done otherwise =df In C, if he had
chosen to do otherwise and…, then Bob would have done otherwise’ (p. 129,
ellipsis original). To make the argument demonstrably valid, we have
to finish the job and explicate that premise in terms of possible worlds.
If we do so in the normal way, according to roughly Stalnaker-Lewis ‘similarity’
semantics and making the most natural judgments of similarity, the resulting
formula does not combine with the previous premises to entail the needed
contradiction. (If we suspect that the hypothetical analysans should
be treated as a backtracker,<9> and apply a natural similarity
analysis for backtrackers, the resulting translation leaves the argument
even more obviously invalid.) So Tomberlin has failed to deduce a
contradiction from the original assumption.
A similarly a priori and very ingenious modal incompatibilist
argument has recently been devised by Ted A. Warfield.<10>
There is some question whether the argument is in fact valid even as already
formulated into modal notation,<11> but in any case, two English
sentence-schemata originally offered by Warfield have to be translated
into modal notation in such a way as to make it valid. (The schemata
are ‘P is true and there’s nothing anyone is free to do in the circumstances
that even might result in ~P’ and ‘P is true and there’s nothing anyone
is free to do in the circumstances that would definitely result in ~P’
(p. 173).) I would contend that the translations needed to make the
argument valid would have to be tendentious in the characteristically philosophical
way, though I cannot argue that here (or even sketch Warfield’s complex
modal argument).
Thus, the incompatibilist’s tendentious assumption
need not take the form of a principle (though one can always reconstruct
it as such). In these would-be purely modal arguments it can take
the form of either a failure to translate in detail, leaving a gap in the
argument, or a highly disputable translation.
So, vs. (1) and (2): (1) is false because
nothing is ‘prima facie incompatible’ with anything unless there is a marked
air of logical contradiction. (2) might yet be shown
to be true, but induction over spirited and ingenious attempts by excellent
philosophers argues otherwise.
4. Against thesis (3): Incompatibilists
often challenge compatibilists to say what ‘free action’ means, if it does
not mean an action that is physically undetermined. (Recall our opening
quote from Chisholm.) And compatibilists have leaped to respond;
Stace and Ayer, for example, offered their infamous hypothetical analyses
of ‘free action’,<12> according to which my action was free iff,
roughly, had I wanted / chosen otherwise, I would have done otherwise.
Such analyses were promptly attacked by Austin, Chisholm, Keith Lehrer
and others.<13>
I think the compatibilists have made a big strategic
error. If my previous points, against (1) and (2), are right, the
compatibilist has no obligation to offer any competing analysis
of ‘free action’. I believe the compatibilists should have balked,
and merely insisted that there is a perfectly good sense of ‘free’
in which we act freely despite our actions’ being the determined result
of pre-existing conditions.
Notice, I said they should have balked, not
just that they would have been within their dialectical rights to have
done so. Notice particularly that in capitulating and consenting
to offer analyses, they opened themselves to a kind of attack whose dialectical
force is weak but whose rhetorical force is strong: Their opponents
could and did vigorously attack the analyses, thereby making it look as
though there were something wrong with the compatibilist position in itself.
Think about it: On any philosophical
topic, the person who propounds an analysis is going to get creamed.
Philosophical analyses virtually never work, but are lacerated by counterexample
after counterexample. So by agreeing to propose a particular analysis
of ‘free action’, our compatibilist is entering a contest s/he cannot hope
to win—not because there is anything wrong with compatibilism or
because ‘free’ really does mean whatever the incompatibilist thinks it
does, but only on the entirely general grounds that in the game of philosophical
analysis, the analysts’ opponents nearly always win.
Compare J.J.C. Smart and his famous ‘topic-neutral
translations’ of mental ascriptions.<14> They were offered
in response to each of three objections to Place and Smart’s Identity Theory
of mind: the claim that mental ascriptions simply entail the existence
of nonphysical states or events, the claim that the Identity Theory violated
Leibniz’ law, and the more complicated ‘Objection 3,’ attributed to Max
Black in Smart’s footnote 13. Smart contended that mental ascriptions
are topic-neutral, in that they entail neither that the states and events
ascribed are nonphysical nor that they are physical. (Never mind
whether this would in fact have blocked the second and third objections.)
Smart sought to show that mental ascriptions are topic-neutral by providing
synonyms or paraphrases of them that are both adequate as paraphrases and
obviously topic-neutral. (Notoriously, ‘I see a yellowish-orange
after-image’ became ‘There is something going on which is like what is
going on when I have my eyes open, am awake, and there is an orange illuminated
in good light in front of me, that is, when I really see an orange.’)
Allies and critics alike seemed to find this entirely
appropriate. David Lewis and David Armstrong offered plainly topic-neutral
meaning analyses of their own; Michael Bradley, Frank Jackson and other
critics attacked Smart’s paraphrases, to good effect.<15>
But, first, why should we expect that an English expression that is in
fact topic-neutral must also have a distinct synonym in English that is
more obviously topic-neutral? Second, as above, why should we expect
philosophical analysis here to produce greater consensus than it practically
ever does? And, third, remember our dialectical points against (1)
and (2): In a controversial case, non-entailment—hence, here, topic-neutrality—is
the default. The burden is on Smart’s opponent to show that mental
ascriptions do entail the existence of nonphysical items.
Smart made the strategic (not philosophical) error
of venturing onto extremely dangerous ground when he was quite safe where
he was. So too the free-will compatibilist who offers an irenic analysis
of ‘free action’. Let’s not do it. And let’s not be bothered
by the failures of others’ analyses. Chisholm was wrong: There is
no joke on us.
5. Against (4): If (1)-(3) are not true,
then there is no conceptual problem about free will and determinism; so
there is no further asymmetry to underwrite (4). (I nearly wrote,
‘then there is no prima facie problem about free will…,’ but that would
have been silly. Of course there is a prima facie problem about free
will and determinism, or so much would not have been written about it and
we would not be holding this session today. What there isn’t is a
conceptual problem.)
The reason I earlier expressed doubt about whether
(4) is just false is the following line of reasoning. Just
suppose, contrary to this paper’s contention, that free will and determinism
are incompatible, so that if determinism is true then there cannot possibly
be free will. Then, despite standard claims that in that case interpolating
physical randomness would not help, it is still theoretically possible
to work out a libertarian theory of agent-causation sitting atop physical
indeterminism, that would allow and account for free will. So in
principle, indeterminism still goes better with free will than does determinism.
(I am not persuaded by that argument, but I do not want to pursue the matter
here.)
6. Now I am going to offer a Moorean
argument for compatibilism, much the sort of argument Moore would use against
idealists and other anti-realists and skeptics.<16> In
considering an anti-realist view, he would first derive from it a very
specific negative consequence regarding his own everyday experience.
For example, take the idealist claim that there are no material objects.
From it, Moore would deduce that he himself had no hands--hands being clear
cases of material objects.
Of course the idealist had defended the nonexistence
of material objects. Let’s suppose that the defense had taken the
form of a deductively valid argument. The argument must of course
have had ultimate premises, themselves undefended. So it is an argument
that looks schematically like this:
(P1) ....
(P2) ....
.
.
[steps]
.
.
______________
\ (C) There are no material objects. QED
—to which we may add as a corollary,
\ (C') I do not have hands.
We are supposing the argument to be valid.
But that is to say only that each of the sets {P1,...Pn, ~C}
and {P1,...Pn, ~C'} is inconsistent. The idealist of
course wants us to accept the premises and therefore to accept C and C'
on the strength of them. But nothing about the argument itself forces
us to do that, since if we wish to deny its conclusion we have only to
reject one of the premises. Any argument can be turned on its head.
Elsewhere<17> I have argued more generally
that no deductive ‘proof’ can be anything more than an invitation to compare
plausibility: Of the propositions P1,... Pn, and ~C', which is the least
plausible or credible? The proof affords no deeper investigation.
Applying the crucial question of plausibility comparison
to any specific argument for idealism concerning the external world, Moore
thought its answer was painfully obvious. Since the reality of material
objects is directly entailed by something Moore already knows to be true,
that he does have hands, the culprit must be one of the other members of
the inconsistent set; it must be one of the premises that is false.
It may be interesting to try to decide which one, but that is not necessary
in order to vindicate our common-sense belief in the reality of material
objects.
To put it that way sounds arbitrary and question-begging,
and of course Moore has been widely accused of both faults. Why should
he get to choose ~C' over the argument’s premises and protect it against
them? That comes close to merely announcing that the idealist is
wrong.
The nonrhetorical answer to the foregoing rhetorical
question is this: At least one of the argument’s premises is sure
to be distinctively abstract and philosophical, accepted only because it
somehow appeals to the idealist. And remember that a deductive argument
is only a plausibility comparison. In this example, the comparison
is between (a) ‘Here is one hand and here is another’ and (b) a purely
philosophical premise such as McTaggart’s assumption that every existing
thing has proper parts that are themselves substances. You be the
judge. How could a proposition like (b) be considered as plausible
as (a)? How could you possibly be more confident that every existent
thing has proper parts that are substances, than that you have hands?
The epistemic credentials of metaphysical premises
(often called ‘intuitions’) are obscure. It is hard to say why a
given metaphysician should be strongly attracted to a particular such premise,
such as (b), when doubtless we can find another metaphysician--perhaps
only in another part of the world or another era, but possibly just next
door--who firmly rejects it. By contrast, Moore has excellent grounds
for the competing proposition (a): He remembers seeing and feeling his
hands on millions of occasions, and he can do so again at will. A
forced choice between (a) and (b) has got to favor (a).
7. Before we get back to free will,
here are six important caveats regarding Moore’s technique: First,
whatever one now thinks of Moore’s response to the idealist—in particular,
even if one is not convinced of the plausibility comparison—Moore has not
begged the question against the idealist. In judging that
one of a pair of propositions is more credible than the other, one may
be mistaken, but it is no dialectical offense (unless, perhaps, the other
proposition is just the negation of the first, which is not the case here).
Second, it would not help the idealist to claim
that her/his philosophical premise is analytic, or a somehow “conceptual”
truth, and so not in need of defense. Even if one is unpersuaded
by Quine of the nonexistence of such truths, the appeal will not help the
idealist here, for no one who reasonably thinks that the premise is false
is going to be converted by the bare assertion that the principle is conceptually
true.
Third, contra many of Moore’s critics over the years,
Moore is not clinging to his commonsense beliefs come what may and treating
common sense as sacred and invulnerable to criticism. Moore never
held that common sense is irrefutable. Common-sense beliefs can be
corrected by careful empirical investigation and scientific theorizing,
which is what happened in, e.g., the case of the earth’s shape and
motion. The point against the idealist is that philosophers
are not empirical investigators or scientists. McTaggart provided
no evidence for his claim that every existent thing has proper parts that
are substances; it just seemed true to him, for some reason. Though
common sense must yield to evidence, it need not yield to bare metaphysical
pronouncement.<18>
Fourth caveat: It’s important to see that
the argument contains no premise about commonsense propositions
themselves, e.g., not that we should give commonsense beliefs considerable
weight, or that commonsense beliefs are prima facie justified, or that
(good God) they have a ‘right of ancient possession’<19>.
It is not that ‘I have hands’ etc. are known or justified in virtue of
their being commonsense propositions. It is just that they are individually
more plausible than are the premises of any philosophical argument intended
to show that they are false. (A later philosophical explanation
of their plausibility might advert to their being commonsensical, though
I myself take a different line.)
Fifth, do not be too quick to dismiss Moore’s method
as shallow and superficial, disrespectful of our need for a deep philosophical
critique of common sense. There is an old and well-entrenched idea
that philosophy can get above, or beneath, the body of belief constituted
by common-sense-plus-science, and subject that body as a whole to deeper
rational examination. I reject that idea, essentially on the grounds
of what I have said earlier about the unprobativeness of deductive arguments;
I have criticized it more extensively elsewhere.<20>
And, sixth: To make my point, I do not need
a theory of plausibility/credibility. Granted, the psychological
basis and normative authority of ‘plausibility’ judgments are important
philosophical issues, but they are just that: philosophical issues.
Actual plausibility comparisons made in real life do not depend on having
a well justified theory of plausibility—else only professional epistemologists
could make them. That people often ride the bus is more plausible
or credible than that a BMW will do over 120 mph, or that more people drive
vintage Jaguars than drive Chevrolets, or that there is life somewhere
else in our galaxy, or that the cause of an idea must have at least as
much formal reality as the idea itself has objective reality. I do
not have to have any philosophical theory of plausibility in order to be
entirely justified in making such judgments, any more than I have to have
a philosophical theory of meaning in order to know what my wife has just
said.<21>
8. And finally we can state the argument
for free-will compatibilism.
I used to claim that a qualified, macro-event-level
version of determinism is itself common sense.<22> That
has proved to be problematic, for it may be a case in which a commonsense
proposition, even the qualified version of determinism, is refuted by compelling
philosophical argument based on indeterminist science. But I need
not stand by that claim. For purposes of my Moorean argument, all
determinism needs to be is: not an affront to common sense.
In any case, the incompatibilist must assume determinism
for the sake of argument. And whether or not it is true, numerous
commonsense claims of free action always will be more plausible than are
the purely philosophical premises (or translation lore etc.) of
any argument designed to convince us of incompatibilism. So we reject
at least one of those premises in each case. Since the incompatibilist
argument fails and compatibilism is the default (cf. again the general
methodological point, section 2 above), compatibilism rules. Thus,
to say the least, it is hard to imagine how compatibilism could be rationally
discredited.
9. Two more caveats are immediately
needed.
I am not saying that compatibilism is a commonsense
view. Ekstrom considers such a claim;<23> I am not sure
whether she rejects it, though she certainly denies that it is a good reason
for embracing compatibilism. I firmly reject it. Compatibilism
is a controversial philosophical thesis. (Nor do I buy the ‘Mind
argument’ that incompatibilist accounts are incoherent.<24>)
Further, in insisting that some of our actions are
free, I am not committing the magician’s-assistant fallacy, i.e., taking
the fact of failing to introspect determining causes of my actions as a
successful introspecting that the actions are free. Nor am I making
any other (direct) appeal to phenomenology.
10. I contend, then, that every incompatibilist argument is bound to fail. That is not to say that each will fail in the same way. But to get a feel for the failure, let us take a quick look at one example, an influential and apparently powerful incompatibilist argument, the ‘Consequence argument’ due variously to Carl Ginet, David Wiggins, Peter van Inwagen and James Lamb.<25> For convenience, let us focus on van Inwagen’s 1983 version:<26>
[box]S
[box](S -> A)
_________
\ [box]A,
where the box is interpreted as ‘unalterability’ of some sort, A is
the performance of an arbitrarily selected future action of mine, and S
is a total efficient cause of A existing before I was born. (Here
as always we assume determinism, in this case for conditional proof.)
The argument’s appearance of validity is unmistakable. And if we
construe the box as, unalterability by me in particular, its conclusion
denies me free will.
Michael Slote argues that although this inference
is attractive because the box is felt to be ‘agglomerative’ ([box]X , [box]Y
|- [box] (X & Y)), agglomerativity fails for some real-life modalities.<27>
(He focuses on agglomerativity because he thinks van Inwagen’s inference
proceeds by agglomeration followed by closure under necessity, but as we
shall see, this interpretation is inessential to the objection.)
Consider, e.g., nonaccidentalness in the everyday sense. Slote
explicates the nonaccidentalness of an event in terms of the event’s being
the outcome of what he calls a ‘routine plan’ (RP). (In virtue of
the plan, the event was quite normal and to be expected.) Now (p.
15), one day in a bank there is an accidental meeting between Jules and
Jim. Each of the two has been sent to the bank ‘as part of a well-known
routine or plan of [respective] office functioning.’ Thus, it is
no accident that Jules arrives at the bank when he does, and it is no accident
that Jim arrives at the bank when he, Jim, does. But it is entirely
accidental that both are there at the same time. Jules’ presence
in the bank was necessitated by RP1 and Jim’s presence there was necessitated
by RP2, but there is no RP that necessitated the simultaneous Jules’-presence-and-Jim’s-presence,
because in particular the amalgam RP1+RP2 is not itself a RP.
[boxRP1](Jules
arrives at the bank at tb)
[boxRP2](Jim arrives at the bank at tb)
_______________________________
--but nothing of the form [boxRPn](Jules arrives at
the bank at tb & Jim arrives at the bank at tb)
follows, because there is no such RPn. Agglomeration fails.
The case of the Consequence argument’s premises
is parallel, except for being a modalized Modus Ponens rather than modalized
Conjunction Introduction. The analogue of an RP is what I shall call
a ‘me-excluding determinant.’ Why is S, the total efficient cause
of A existing before I was born, unalterable by me? Because it was
in place quite independently of my desires, wishes, intentions, for that
matter beliefs, and whatever other conative structure would be relevant
(hereafter just ‘my CS’), because I neglected to exist at the time.
Why is the material conditional S -> A unalterable by me?
Because it is a logical consequence of the laws of nature, and both logic
and the laws hold quite independently of my CS. It is in that sense
that S and S -> A are me-excluding determinants (MEDs).
But the individual MEDs differ as between van Inwagen’s
first premise, [box]S, and the second, [box](S -> A). We have
[boxMED1]S
[boxMED2](S -> A)
______________
.
But nothing of the form [boxMEDn]A follows, because
there is no such MEDn. In particular, the amalgam S & (S
-> A) is not a MED, for it does not determine A in a way that bypasses
my CS. Since A is a future action of mine, A is hardly unaffected
by my CS. In fact, my CS is an, if not the, prominent element of
A’s total efficient cause. To be unalterable by me is to be determined
or necessitated in a certain way, viz., in a me-excluding way. S
and S -> A are necessitated in that way, but A, though necessitated
in other ways, is not necessitated in that one. The inference-pattern
fails.
To put it back in terms of agglomerativity for Slote’s
sake: In general, even where Z is entailed by the conjunction X &
Y, that X is determined by a MED and Y is determined by a MED does not
entail that Z is determined by a MED. So [box]A cannot be derived.
11. ‘Oh, spoken like a good Soft Determinist!,’
van Inwagen might reply.<28> Indeed, my moves in this paper
against Tomberlin’s and van Inwagen’s arguments may have sounded at every
turn as though I had said, ‘Let’s all remember that Soft Determinism is
true, and just stiffarm whatever contrary claim we have to in order to
save our view.’ Van Inwagen’s argument schema seems valid to him
on what he considers any reasonable interpretation of the box; modalities
such as mine that fail to support the schema are conspicuously already
congenial to the Soft Determinist. Van Inwagen admits that his argument
will never convince the die-hard compatibilist,<29> but for his
part he cannot hear any Soft-Determinist-leaning interpretation of the
box as a reasonable interpretation. It is at best a stalemate.
I believe it is no stalemate, and that Slote and
I win. First, our objection to the Consequence argument does not
presuppose compatibilism, let alone the truth of Soft Determinism.
Our objection is that the argument employs modalities that are, like virtually
every other modality expressible in English, relative modalities, and that
on one entirely reasonable interpretation the argument’s premises are true
and its conclusion false. Granted, the interpretation is guided by
a conception of action that is indeed congenial to Soft Determinism.
(And I admit here and now that that will be my offstage strategy in responding
to every incompatibilist argument.) But it does not follow that the
objection presupposes the compatibility of free will with determinism;
it does not. Of course, so far as I can see, van Inwagen’s controversial
inference does not presuppose incompatibilism either, so this first point
does not show that we are not in stalemate. But if we are in stalemate,
it does not take the form of mutual question-begging.
Second, I have pointed out that, so far as has been
shown, the Consequence argument is invalid. To respond, van Inwagen
or another incompatibilist would have to either add another premise, or
block my counter-interpretation in some principled way. And, as before,
the premise or principle thus introduced would have to be more plausible
than the commonsensical claim that I did A freely in the sense germane
to responsibility. My doubt that the incompatibilist can do that
is my reason for denying that we are in stalemate. Remember that
the compatibilist bears no corresponding burden; if some conclusion does
not obviously follow from some premise, we can only wait to see why the
proponents of entailment think it does follow.
In ‘Reply to Christopher Hill’ (ibid.), van Inwagen
offers a sensible dialectical model (p. 58): Think of the issue as
a debate conducted by a compatibilist on one side and an incompatibilist
on the other, but before an audience that is agnostic on the issue.
Each of the two debaters is trying to convert, not necessarily the opposing
debater, but the hitherto neutral listeners. So, as the incompatibilist
debater, van Inwagen need not restrict himself to premises that would be
acceptable to the compatibilist, but must only present an overall case,
including replies to the compatibilist’s opening points, further rejoinders,
etc.) that will or should sway the agnostics. In like wise, the compatibilist
may use premises that would be unacceptable to the incompatibilist, so
long as they are likely to be granted by the neutral audience.
That is a good test. And the ultimate point
of my Moorean argument is to show that the audience will always be forced
to choose between, on the one hand, a host of commonsense propositions
about their and others’ doing things freely, and on the other, a purely
philosophical principle that is controversial even among philosophers.
In the nature of things, I have argued, philosophy will always lose that
one. Compatibilism still rules.<30>

4 For example, Ekstrom (op. cit, p. 8) eschews it, arguing plausibly that the exact relation between freedom and moral responsibility is unclear and disputable. But the alternative seems to be either metaphor or characterization vapid enough to be all too obviously available to the compatibilist (‘our actions are truly attributable to our selves…, ultimately up to us’ (Ekstrom, p. 3)).

6 N.b., I will not contend, as some compatibilists have in attacking incompatibilist arguments, that the principle begs the question.

26 There are now a number of interestingly different versions of the Consequence argument, subject to somewhat different sets of objections. These are nicely catalogued and discussed by Ekstrom, op. cit., Chapter 2. I criticize van Inwagen’s version more extensively in Chapter 8 of Modality and Meaning (Dordrecht: Kluwer Academic Publishing, 1994), though that discussion is marred by some vicious copy-editing errors.
