Free Will in Aristotle?

A recent large book by Olivier Boulnois, Généalogie de la liberté [Genealogy of Freedom] (2021), provides great detail on the emergence of the notion of free will (liberum arbitrium in Latin). I have previously mentioned his Être et représentation (1999), which gives fascinating documentation of the role of Duns Scotus in the formation of modern notions of representation, and metaphysics as ontology. Boulnois has written extensively on medieval philosophy. Like Alain de Libera, he turns a broadly Foucaultian “archaeological” method in the direction of showing the large and largely unknown role of medieval philosophy in the development of common Western philosophical concepts. This post will focus on a part of his discussion of how Aristotle stands largely apart from later views.

Early on in the present work, Boulnois cites the first sentence of G. E. Moore’s Principia Ethica:

“It appears to me that in Ethics, as in all other philosophical studies, the difficulties and disagreements, of which its history is full, are mainly due to a very simple cause: namely to the attempt to answer questions, without first discovering precisely what question it is which you desire to answer” (quoted in Boulnois, p. 34).

Boulnois notes how Latin translations extensively transformed the meanings of Aristotelian concepts.

“Is free will proper to the human? All of medieval and modern reflection on action rests on this thesis…. The concept of proairesis is analyzed for the first time in book III of the Nicomachean Ethics” (Boulnois, p. 133, my translation throughout). “To begin with, must we follow the [12th century Latin] translation of Burgundio? Does proairesis really mean free will?” (p. 134).

“With the translation of proairesis by ‘choice’, the key concept of Aristotelian ethics is integrated into the semantic field of will. The Burgundian point of intersection, which connects Aristotle and [the Church Fathers] Nemesius and Damascene in the same bundle of translations, constitutes a second origin of proairesis as free will in the 12th century” (p. 137). “Aristotle defines proairesis as a kind of desire joined with deliberation (with discourse)” (p. 139). “With Aristotle, we are indeed far from the medieval and modern interpretation, which speaks of choice (electio)” (p. 141).

Until now I have followed Joe Sachs’s translation in using “choice” myself. Sachs uses the English word with the same root as the French that Boulnois is questioning, but he explains it in terms of Aristotle’s definition just mentioned. But as we will see in an upcoming post, the Latin tradition gave it a voluntaristic coloring that is foreign to Aristotle.

“The most rigorous translation seems to be ‘resolution’…. Resolution introduces logos and time” (p. 140). “The object of our resolution is first of all the object of our desire, insofar as this results from a deliberation” (pp. 140-141). “Our moral character depends not on our theoretical attitude but on the ensemble of our resolutions, the repetition of which constitutes our disposition to act, indeed our aptitude for beautiful actions” (p. 142).

This ensemble of our resolutions sounds like the commitments of which Brandom and other contemporary writers speak.

“Since Cicero, the boulesis of the Stoics has been translated to Latin by voluntas [will]. But the Stoics affirm that such a mastery of impulse is found only in the sage…. It is only later, with Augustine, that this prerogative of the sage becomes a faculty accessible to all. Our concept of will, as capacity to consent or not to our representations, carries all this history. But in Aristotle, boulesis always designates the desire that pertains to that part of the soul that is capable of speech. It is a form of desire that is enunciable, intelligible…. Boulesis indeed is a wish: a wish does not require the existence of a will; like all desire, it is moved by its object” (p. 143).

“Among our desires, resolution results from a deliberation, which deploys itself in language…. The true principle of our resolution is of the order of language and of thought. Like all living beings, the human is necessarily moved by what appears to her as desirable; but in distinction from the other living beings, it is through speech that the desirable appears to her…. Resolution bears on action that can be accomplished by us…. There is only a place for deliberation when several lines of action are possible…. We deliberate on that which no one can do in our place” (p. 145, emphasis in original).

Here the resolution of deliberation is explicitly grounded in language and thought, and not in an anachronistic non-Aristotelian notion of a faculty of will.

“It is necessary to underline: Aristotle does not exactly say that the resolution depends on us. What depends on us is the action that is the object of that resolution…. Aristotle does propose a theory of decision, or of resolution, but not a theory of freedom of choice, or of free will” (pp. 145-146, emphasis in original).

Unlike Boulnois here, some 20th century writers have used “decision” in the sense that Boulnois gives to “choice”.

“Such actions are ontologically contingent: they could [also] not be. The metaphysical tradition deduced from this the existence of a power of choice, of a will or a free will” (pp. 146-147).

The important point here is that this “metaphysical tradition” does not include Aristotle.

“Nothing obliges us to understand contingency in an absolute manner, and as subject to our power. Aristotle refers to the ensemble of actions that depend on us (eph’ hemin) in general (in the sense of a collectivity: the humans, the agents, the citizens), but not to those that depend on me (here and now)…. But Aristotle never claims that an agent has, other things being equal, at a given instant, the capacity to do one thing or its contrary, to act and not to act. ‘What depends on us’ is a generic capacity, proper to humankind, and not to some particular individual, here and now. Reciprocally, in insisting on the idea that deliberation is the cause of our resolution, Aristotle holds that at the interior of this bivalence, we more often see what the logos presents as desirable” (p. 147, emphasis in original).

“In this context, what is the principle of action?” (p. 150). He quotes Aristotle, “and the principle of resolution is desire and reason…. What affirmation and negation are in thought, pursuit and flight are to desire…. For resolution to be good, it is necessary at the same time that the discourse be true and the desire just” (p. 150).

Boulnois summarizes, “Thus the properly human principle of action is resolution, that is to say the conjunction of desire and of logos in the pursuit of an end” (p. 151).

He turns to the background that Aristotle is responding to.

“The sophists affirm that every desire is good; Plato, that we can only truly will the true or absolute good” (ibid). “While the sophists identify freedom with the capacity to do what we want, and Plato with sole adherence to the Good, Aristotle proposes a third way: ethical freedom is the art of deciding well, of arriving at the resolution the circumstances require…. The resolution taken by the homme de bien [literally, “man of the good”] is indeed a point of coincidence between the apparent good (which all seek) and the true good (that she discerns). In leaving behind the confrontation between sophists and Platonists, Aristotle has recourse neither to a relativism of appearances nor to an objective norm; in the element of virtue (and of desire), he aims at a coincidence between the phenomenon of good and its truth” (p. 152).

This Aristotelian idea of a point of coincidence between appearance and truth was later taken up by Hegel.

“Is it necessary to say that resolution is free? Does it consist in a choice?… Aristotle never makes the concept of freedom intervene in relation to the question of choice, nor even that of willingness” (p. 153). “Nevertheless, Aristotle knows and uses a concept of freedom (eleutheria). But this pertains to politics and not to the theory of action” (ibid, emphasis in original).

“The Latin translation not withstanding, ‘hekousion’ (willing) does not mean ‘voluntary’ (voluntarium); it is rather the mode of our action, except in cases of constraint or ignorance. Proairesis does not mean ‘free will’ (liberum arbitrium), but decision, resolution… Freedom is the ethical horizon of our action, and not the metaphysical attribute of a will that Aristotle did not envisage” (p. 154).

“It is indeed possible to analyze human action without postulating in the agent a central instance of arbitration, and without inscribing her in a physical determinism…. Ethics is indeed thinkable without a theory of will” (p. 155).

As I have noted many times, Plato and Aristotle founded ethics without the later notion of a faculty of will.

“Ethical action does not necessarily require a freedom of choice. It depends on a resolution (proairesis), which mainly refers to a dimension of anticipation, and does not always imply a choice. Ethics is indeed thinkable without the doctrine of free will” (ibid).

Here again the emphasis is on something like commitment.

“Resolution presupposes a process of deliberation in the agent: she at least implicitly evaluates the reasons to do x rather than nothing; that which she does is not imposed on her from the outset. That is to say that for her, there are a multitude of options and reasons to act” (ibid, emphasis in original).

Deliberation is concerned with the goodness of reasons.

“A stranger to the metaphysical problem of free will, freedom is ethical in essence; it consists in the ability to act well; it is only acquired at the completion of an education in virtue” (ibid).

“All thought about action situates itself in the horizon of the good, and freedom is nothing other than liberation from the bad” (p. 156).

It is ethics that founds freedom, and not freedom that founds ethics” (ibid, emphasis in original).

“On the plane of finite existence, no one knows if they have absolutely accomplished the best action. In the same way in their reflections on our moral lack of power, Aristotle and Ovid speak of that which is ‘better’ (comparative) and not of that which is ‘best’ (superlative)” (ibid).

Free Will in Plotinus

“Can there be question as to whether the gods have voluntary action? Or are we to take it that while we may well inquire in the case of men with their combination of powerlessness and hesitating power, the gods must be declared omnipotent, not merely some things but all lying at their nod? Or is power entire, freedom of action in all things, to be reserved to one alone…?” (Plotinus, Enneads VI.8.1, MacKenna tr., p. 595).

Plotinus in his treatise “On Free Will and the Will of the One” makes arguments that are unprecedented in the previous history of Greek philosophy. The treatise seems to show some (perhaps indirect) influence from the voluntaristic theology of Philo of Alexandria, as well as from Stoic theories of assent and of the so-called hegemonikon, a sort of ruling master faculty in humans that begins to approximate modern notions of a strongly unitary “mind”. It is noteworthy that free will and omnipotence are mentioned together from the outset.

It is especially common for writings on this subject to go through many twists and turns, since there are obvious appearances pointing in conflicting directions. Plotinus ends up advocating a fairly extreme position on these matters, but he is a serious enough thinker to feel the need to deal with conflicting evidence.

“The very notion of power must be scrutinized lest in this ascription we be really setting up an antithesis of power (potency) and Act, and identifying power with Act not yet achieved” (ibid).

Here he is implicitly responding to Aristotle. Given that he in general both shifts the meaning of Aristotelian potentiality back in the direction of Platonic power and emphasizes the unlimited power of the One unconstrained by any actuality, it is interesting that he recognizes there is an issue with “identifying power with Act not yet achieved”.

“To begin with, what must be intended when we assert that something is in our power; what is the conception here?” (ibid).

Aristotle had implicitly introduced the consideration of what is “in our power” in discussing moral responsibility for “willing” and “unwillling” actions. This became the basis of a key distinction in Stoic ethics: Epictetus says that only what is in our power is good or evil.

Plotinus writes, “A cardinal question is where we are to place the freedom of action ascribed to us…. But if rage or desire implied freedom we must allow freedom to animals, infants, maniacs, the distraught, the victims of malpractice producing uncontrollable delusions. And if freedom turns on calculation with desire, does this include faulty calculation? Sound calculation, no doubt, and sound desire; but then comes the question whether the appetite stirs the calculation or the calculation stirs the appetite…. Further, every emotion is preceded by some meager reasoning; how then can a compelling imagination, an appetite drawing us where it will, be supposed to leave us masters in the ensuing act?” (VI.8.2, p. 596).

Here he clearly recognizes that meaningful freedom must be something more subtle than just arbitrarily doing what we want. No emotion is completely devoid of reason, but he recognizes that we are often driven mainly by imagination and appetite. This will not qualify as free.

“We may be reminded that the Living Form and the Soul know what they do. But if this knowledge is by perception it does not help us toward the freedom of the act; perception gives awareness, not mastery” (p. 597).

He uses the term “knowledge” loosely here, but recognizes that mere awareness is superficial.

“We have traced self-disposal to will, will to reasoning and, next step, to right reasoning; perhaps to right reasoning we must add knowledge, for however sound opinion and act may be, they do not yield true freedom when the adoption of the right course is the result of hazard or of some presentment from the fancy with no knowledge of the foundation of that rightness” (VI.8.3, p. 597).

Up to this point he has mentioned will, but not given an account of it. The account comes a bit later in the text. But it is clear that he sees will as intimately involved with reason and intellect, as well as being a free power to choose. There is implicit tension between these two aspects, which will affect many later thinkers as well.

“Self-disposal, to us, belongs to those who, through the activities of the Intellectual-Principle, live above the states of the body” (ibid).

Now we come to what seems to be the main point of his solution. Pure intellect and what he calls the separated soul are by definition exempt from the passions and imagination that sway us embodied humans this way and that. But he maintains that we have an intimate connection to the separated soul, and that through this connection, freedom can be ours as well.

“Effort is free once it is toward a fully recognized good; the involuntary is, precisely, motion away from a good and toward the enforced, towards something not recognized as a good” (VI.8.4, p. 598).

He remains close enough to Plato and Aristotle to want to also tie freedom to the good, which Plato says all beings desire.

“[B]ut an undivided Principle, a simplex Activity, where there can be no difference of potentiality and act, must be free; there can be no thought of ‘action according to nature’, in the sense of any distinction between the being and its efficiency, there where being and act are identical…. In a principle, act and essence must be free” (ibid).

Here he takes a more radical step, guided by abstract thinking about what “must” be true about Principles. This kind of approach is not completely absent in Plato and Aristotle, but plays a much more central role in Plotinus. He seems to be saying that when we orient ourselves by the separated soul, we are no longer governed by a nature at all.

“If freedom is to be allowed to the soul in its Act, it certainly cannot be allowed in regard to issue, for we are not master of events: if in regard to fine conduct and all inspired by the Intellectual-Principle, that may very well be freedom; but is the freedom ours?” (VI.8.5, p. 598).

If events do not turn out as we had wished, our effective action in the world will not count as having been “free”. He recognizes also that it does not follow automatically that because pure intellect is free, we are free.

“If thus virtue whose manifestation requires action becomes inevitably a collaborator under compulsion, how can it have untrammeled self-disposal? Should we, perhaps, distinguish between compulsion in the act and freedom in the preceding will and reasoning? But in setting freedom in these preceding functions, we imply that virtue has a freedom and self-disposal apart from all act; then we must state what is the reality of the self-disposal attributed to virtue as a state or disposition” (p. 599).

This is indeed the path that he will follow.

“Virtue does not follow upon occurrences as a saver of the imperilled; at its discretion it sacrifices a man; it may decree the jettison of life, means, children, country even; it looks to its own high aim and not to the self-regarding of anything lower. Thus our freedom of act, our self-disposal, must be referred not to the doing, not to the external thing but to the inner activity, to the Intellection, to virtue’s own vision” (VI.8.6, p. 599).

It sounds as though he thinks virtue inheres in the separated soul.

He seems to want to say that virtue is completely independent of any necessity — not only of external compulsion, but also of any constraint by universals. I think Kant sometimes goes too far with the analogy between a “should” and formal necessity; what Plotinus says here suggests he wants to go too far in the opposite direction, effectively denying any real substance to a “should”. Of course he would object to this latter conclusion, since he clearly wants to tie freedom to the good, but it seems to me that it follows anyway. His stance seems to imply that good is whatever a “good” will wills. This is opposite in spirit to Plato’s Euthyphro. Either it is circular, or it implies a kind of voluntarism.

“This makes it all the more evident that the unembodied is the free; to this our self-disposal is to be referred; herein lies our will which remains free and self-disposing in spite of any orders which it may necessarily utter to meet the external. All then that issues from will and is the effect of will is our free action, whether the will is directed outwards or remains unattached; all that will adopts and brings, unimpeded, into existence is in the highest degree at our free disposal.”

Now he has turned things around so that all willing is free. This depends on a new assumption that seems to locate the will in the separated soul, which does make sense if we accept what he has said. The claim seems to be that we can say that the will of the separated soul chooses which “orders” to give in unconditional freedom, in spite of the fact that the content of all particular orders is conditioned by external factors.

“The contemplating Intellect, the first or highest, has self-disposal to the point that its operation is utterly independent; it turns wholly upon itself; at rest in its good it is without need, complete, and may be said to live to its will; there the will is intellection: it is called will because it expresses the Intellectual-Principle in the willing phase and besides, what we know as will imitates this operation taking place within the Intellectual-Principle” (p. 600).

He goes on to argue at length that since pure intellect is free, the One must be so to an even higher degree. Many have seen a strong element of necessity in his view of the procession of everything else from the One. Plotinus seems elsewhere to say that if we look bottom-up, there appears to be necessity, but here he claims that from a top-down perspective, the One is absolutely free, and beings inherit a portion of that freedom through the operations of procession. By means of the separated soul, he claims that we participate in this.

Others might question whether we humans really have access to such a top-down perspective. Basically no one — even the later Greek neoplatonists — has fully embraced Plotinus’ notion of the separated soul. But many later monotheists found the sort of conclusions that he reached attractive nonetheless, and sought alternate grounds for embracing them. For example, although the scholastic “intellectual soul” is embodied rather than separated, like Plotinus’ separated soul it has many very “strong” attributes that do not come from Aristotle.

Is and Ought in Actuality

Aristotle regards the priority of actuality over potentiality to be one of his most important innovations. He regards it as a necessary condition for anything being intelligible. Along with the primacy of the good and that-for-the-sake-of-which in explanation, it is also central to his way of arguing for a first cause.

The Western tradition generally did not follow Aristotle on these points. Arabic, Hebrew, and Latin monotheisms have most often treated God as an absolute power, seeking to put unlimited omnipotence first in the order of explanation, before goodness. Christians were happy to criticize occasionalism in Islam, but theologians like Duns Scotus and William of Ockham defended an extreme sort of theological voluntarism, which was taken up again by Descartes. In the 19th century, Kierkegaard valorized Abraham’s willingness to sacrifice his son as unconditional obedience to God, claiming that faith should take precedence over ethics generally. In the 20th century, Sartre defended unconditional free will for humans, while asserting a militant atheism and the absurdity of existence. His currently influential follower Alain Badiou goes even further. He bluntly says that concern for ethics is a waste of time, and that dialogue and democracy are a scam — not just in particular cases, but in general.

Mainstream views of religion have always insisted that the absolute power is also absolutely good, but have been unable to show why or how this is the case. This has opened the door to simplistic but unanswerable arguments that the facts of the world cannot be reconciled with claims that it is governed by a good absolute power.

Instead of sacrificing ethics and the good on either religious or secular grounds, we should put them first. Leibniz argues that an emphasis on the absolute power or arbitrary will of God is bad theology, and effectively makes God into the kind of tyrant that Plato denounced (see also Euthyphro; Arbitrariness, Inflation).

Aristotle’s first cause doesn’t govern the facts of the world. It is the world’s normative compass. It is the pure good and pure fulfillment that all things seek, according to their natures and insofar as they are capable. Or as Hegel might say, it is pure Idea.

The priority of actuality is a priority of the good and of normativity. For Aristotle, we shouldn’t call something “actual” just because it exists or is the case. Rather, something is actual when it is the case that it is fulfilling its potential, as it “ought” to do.

It is not a matter of pure moralism either though. Actuality does involve an element of being the case; it is just not reducible to that. What is true also matters quite a lot in the determination of what is right, even though it is not all that matters. Every particular good is interdependent with particular truth. That is why Aristotle seems to make the understanding of causes into one of the most important elements of virtue, while at the same time cautioning us that ethics is not a matter of exact knowledge.

We are looking for a kind of mean here. What is true matters for what is right, but what is right also matters for what is true. Truth is not reducible to a matter of neutral fact. There can be no truth without intelligibility, and there can be no intelligibility without taking normative considerations into account in interpretation.

The Dreaded Humanist Debate

In 1960s France, there was a huge controversy among philosophers and others over so-called “humanism”. Rhetoric was excessive and overheated on both sides of the debate, promoting unhealthy and shallow polarization, but the topics dealt with were of great importance.

To begin to understand the various positions on this, it is necessary to realize that connotations of the word “humanism” in this context were quite different from what is usual in English. (The third meaning that was listed in Google’s dictionary result at the time I wrote this in 2020, attributed to “some contemporary writers”, did at least have the virtue of expressing a position in philosophical anthropology, which is what was at issue in the French debate, in contrast both to Renaissance literary humanism and to explicitly nonreligious approaches to values. Just checked again in 2025, and it no longer lists this meaning, which is less common in English.)

Europe has an old tradition of self-identified Christian humanism. After the publication of Marx’s 1844 Manuscripts in the 1930s, non-Stalinist Marxists began talking about a Marxist humanism. In France after World War II, even the Stalinists wanted to claim the title of humanist. In his famous 1945 lecture “Existentialism is a Humanism”, the notoriously anti-religious and individualistic writer Jean-Paul Sartre surprised some people by placing his existentialism under a common “humanist” banner with Christians and Stalinists. What they all wanted to assert under the name of humanism was a particular view of what it is to be a human, emphasizing the centrality of free will and consciousness, and identifying humanness with being a Subject.

In the 1960s, these views were sharply criticized by people loosely associated with so-called “structuralism”, including Foucault, Althusser, and Lacan. The “structuralist” views denied strong claims of a unitary Subject of knowledge and action; rejected any unconditional free will; and took a deflationary approach to consciousness. Sartre and others launched vehement counter-attacks, and the debate degenerated into little better than name-calling on both sides.

In my youth, I was exposed first to views from the “humanist” side, and accepted them. Then I became aware of the “structuralist” alternative, and for a while became its zealous partisan.

In the Odyssey, Odysseus had to navigate between the twin hazards of Scylla and Charybdis. Since the millenium, I have emphasized a sort of middle way between “humanism” and “structuralism” — inspired especially by Aristotle and Robert Brandom, and more recently also by Paul Ricoeur.

Now I want to say, there is no Subject with a capital “S”, but I am highly interested in the details of subjectivity. There is no unconditional free will (and I even doubt the existence of a separate faculty of “will” distinct from reason and desire), but I am highly interested in voluntary action as discussed, e.g., by Aristotle and Ricoeur. I prefer to sharply distinguish apparently immediate “consciousness” from other-oriented, mediate, reflexive “self-consciousness”, putting most of the philosophical weight on the latter.

Kantian Will

Will for Kant is the ability to act in accordance with a conception of law. In spite of his confusing rhetoric about free will, this is clearly not the voluntarist notion of a faculty superior to reason, free to do or choose any arbitrary thing. However much I dislike images of law in ethics — which by default suggest what Hegel called “positive” or empirically existing, first-order law — acting in accordance with a conception of law is clearly not acting arbitrarily.

Kant also distinguishes between acting in accordance with a conception of law from merely acting in accordance with law. The latter would be mere obedience, without thought. So the important thing is not really the law as such, but thought about how to interpret it. (See also Kant’s Groundwork; Kantian Freedom; The Autonomy of Reason.)

Kantian Freedom

Brandom’s 2007 Woodbridge lectures (reprinted in Reason in Philosophy) opened my eyes to a new and much more positive appreciation of what Kant was trying to say about freedom. Brandom’s treatment is a marvel of clarity in comparison to the tortured arguments of a text like the Critique of Practical Reason. Kant was among the greatest of philosophers, but much of the second Critique seems occupied with producing a square circle, in its attempt to reconcile overly strong Newtonian determinism with the legal and political voluntarism popular among 17th and 18th century theorists like Pufendorf and Rousseau, and related talk about an incompatibilist notion of free will.

Brandom charts a middle path between the extremes of determinism and voluntarism, highlighting Kant’s key insights into freedom as essentially normative and positive and involved with reason, while deemphasizing Kant’s questionable invocations of will and causality in this context. This turns the ugly caterpillar into a butterfly.

The kind of determinism Kant was sympathetic to was the univocal sort, which wants to say not only that that there are sufficient reasons why everything is the way it is, but also that it could not have turned out any other way. I want to say that in hindsight there are always sufficient reasons why everything turned out the way it did, but that in advance, multiple outcomes are possible. (See also Equivocal Determination.)

In terms of the classic medieval debates about the priority of reason or will, Brandom’s reading puts Kant squarely on the side of the priority of reason. Talk about freedom as positive and related to specific capabilities, rather than negative and “infinite”, already rules out voluntarism. Kant’s deep concern with the autonomy of reason is also materially incompatible with any subordination of reason to will.

I think understanding of Kantian freedom should focus on the autonomy of reason, as well as applying something like the Critique of Judgment notion of the free play of the imagination and understanding in reflective judgment to the synthesis of unities of apperception.

After clearing away univocal determinism and voluntarism, we are left with ethics, which seems a good outcome. (See also Structural Causality, Choice; Values, Causality; Kantian Will.)

Strong Omnipotence

The Greek-speaking Jewish theologian Philo of Alexandria (1st century BCE to 1st CE) was perhaps the original antiphilosopher. That is to say, he used some philosophical ideas with learning and sophistication, but was unequivocally hostile to the autonomy of reason, which was something of a commonplace among the Greek philosophers.

For Philo, any equivalent of ethical virtue seems to come exclusively from faith in the revelation of the Greek Old Testament, taken as the literal word of God. To me, this sounds like an unfortunate precursor to today’s fundamentalisms, which ignore all sounder theology, and preclude the very possibility of genuine ethics. Where there is no allowance for virtue independent of one-sided authority, it may become all too permissible to hate whomever is called an unbeliever or heretic. Many other theologians have been far less one-sided, allowing for at least a relative autonomy of reason, and a possibility of genuine virtue independent of sheer obedience to presumed dictates of revelation. With them, a moral philosopher can find common ground.

Philo may have originated the suggestion that Platonic ideas exist in the mind of an omnipotent God. An emphatic supernaturalist, he defended creation from nothing, grounded in an ultra-strong version of divine omnipotence. On this view, God has absolute liberty, and thus can do absolutely any absolutely arbitrary thing at any time, as with the later Islamic occasionalists. Philo explicitly contrasted this view with those of all the Greek philosophers and those influenced by them, who at the very least would expect God to act in ways that are genuinely reasonable and good, and thus put reason and goodness before any will. Unlike the God of Aquinas, for instance, the God of Philo is even supposed to be able to do logically impossible things if he so wills. This is extreme theological voluntarism.

Philonic strong omnipotence is precisely the kind of thing Leibniz later said would make of God an arbitrary tyrant, with disastrous ethical and social consequences. Notions of divine will tacitly assumed to be known with certainty by human authority, and not subject to any inquiry go against the whole better tradition of faith seeking understanding, and make it all too easy to mask hate in the name of supposed holiness.

In all three of the major monotheistic traditions, this dangerous kind of voluntarism has been applied by some to God. Some have gone on to attribute similar supernatural free will to humans as well, on the ground that they are made in the image of a God that has that kind of completely unconstrained freedom. This is using bad theology to justify bad anthropology. As anthropology, it is what Hegel called the illusion of Mastery. Some bad philosophers have simply postulated a similar completely unconstrained “negative” freedom or “freedom of indifference” for humans, without even a pretended explanation of how this could be. (See also Freedom and Free Will.)

My main source for statements about Philo here is the actually sympathetic essay by Harry Austryn Wolfson, in his book Religious Philosophy: A Group of Essays (1961). I always thought of Wolfson as a Spinoza scholar, but Wikipedia says he is actually best known for another, larger work on Philo. The Stanford Encyclopedia of Philosophy has a nice summary of current Philo scholarship. (See also Fragility of the Good; Theology.)

Freedom and Free Will

Plato and Aristotle got along perfectly well with what many people think was no concept of a separate “will” at all. Aristotle nonetheless developed a nuanced account of deliberation and choice, which should have made it plain for all time that no extravagant assumptions are necessary to provide a basis for morality. All that is required for ethical development is that there be things within our power, not that we can somehow magically escape from all determination.

Curiously, the notion of a “freedom of indifference” emerged in Stoicism, generally thought to be a haven of determinism. The Stoic sage is claimed to be completely indifferent and unaffected by passions, therefore completely free. Some monotheistic theologians later applied an even stronger version of this to God. God in this view is absolutely free to do absolutely any arbitrary thing. Some even claimed that because man is in the image of God, man too is supernaturally exempt from any constraint on the will. Descartes claimed that the physical world was wholly determined, but that the human soul is by the grace of God wholly free. (See also Arbitrariness, Inflation.)

Others thought we are free when we are guided by reason. This view takes different shapes, from that of Aquinas to that of Spinoza.

Kant introduced another kind of freedom, based on taking responsibility. Where I decide to take responsibility, I am free in that sense, with no need for a supernatural power. I can take responsibility for things that are by no means fully within my control. Kant unfortunately confuses the matter by talking about freedom as a novel form of causality, while denying that this makes any gap in Newtonian physical causality. (See also Kantian Freedom; Kantian Will; Freedom Through Deliberation?; Beauty, Deautomatization; Phenomenology of Will.)

Hegel too reproduced some voluntarist-sounding rhetoric, but his version of freedom is a combination of both the reason and responsibility views with absence of slavery or oppression. (See also Independence, Freedom.)

Confusion continued into the 20th century notably with Sartre, who claimed that man is free even in prison, and attacked so-called structuralism for allegedly undermining said freedom.

Freedom as reason, freedom as responsibility, freedom as absence of slavery and oppression are all things we should want. As for the rest, see the Appendix to Book 1 of Spinoza’s Ethics (though unfortunately Spinoza is unfair to Aristotle in treating all teleology as supernatural in origin). (See also Subject; God and the Soul; Influence.)

Brandom explicitly mentions theological voluntarism as associated with what he calls the “subordination-obedience model” of normativity. (See also Voluntarism.)
