Here I will discuss a single short passage from Duns Scotus’s Treatise on God as First Principle from a number of different angles, using my own reactions (and quite different and non-medieval reading of Aristotle) as a sort of foil.
The Treatise is one of the most celebrated proofs for the existence of God in the Latin tradition. It also claims to in some meaningful sense demonstrate the nature of God, in a way that is accessible to natural reason.
It is widely accepted that the Treatise is both one of Scotus’s most mature works, and one of those most thoroughly reviewed and edited by Scotus himself. Compared to his massive commentaries on Peter Lombard’s Sentences, it is also far more compact.
(The larger Scotus corpus has been notoriously challenging for scholars to work with. His admirers aver that if he had lived as long as Aquinas, his works would have been equally well polished and edited by the author. As it stands, many were left in very rough form. There is also an unusual amount of divergence in the manuscript traditions, which has greatly complicated the publication of critical editions. Work on critical editions has advanced substantially but is still incomplete, and some of it has been controversial. Scholars have debated at length which of certain manuscripts should be regarded as more authoritative, and this is interwoven with disagreements on questions of interpretation. Specialists also disagree on the relative maturity of thought embodied in some of the texts.)
Several recent scholars have suggested that Scotus may be (in part at least) more Aristotelian than has been thought. Needless to say, this caught my interest. But scholars of medieval philosophy are not required to distinguish the Aristotle I find inspiring from his very different image in the Latin world or the modern one, so an evaluation of this will require careful sifting.
It does seem that in practical ethics, there is a surprising proximity. Also, intriguingly, he calls theology a practical discipline. He devotes most of his attention to what might be called a kind of meta-ethics. But as far as I can tell at this stage of the research, Scotus’s meta-ethics — that is to say, the main part of his theology, as well as his post-Avicennan reinvention of metaphysics — still after all elaborates a forceful and sophisticated voluntarism, in the anti-Aristotelian spirit of the condemnation of 1277. The condemnation is commonly mentioned by scholars as important background for understanding Scotus.
Here is the quote, which Richard Cross reproduces in the introductory section of the chapter “Knowledge and Volition of a First Being” in his Duns Scotus on God (2005):
“[1] The first efficient cause directs its effort toward a goal. Therefore, [it does so] either naturally or by loving it. But not in the first way, because something lacking knowledge directs nothing other than in virtue of something that knows, for the first ordering belongs to the wise. The first [efficient cause] does not direct in virtue of anything [else], just as it does not cause [in virtue of anything else].”
“[2] Something is caused contingently; therefore the first cause causes contingently; therefore it causes voluntarily. The first consequence is proved: any second cause causes insofar as it is moved by the first cause. Therefore, if the first cause moves necessarily, every [cause] is moved necessarily and everything is caused necessarily. Proof of the second consequence: there is no principle of acting contingently other than will, for everything else acts by the necessity of nature, and thus does not act contingently.”
“[3] I do not call contingent everything that is neither necessary or everlasting, but that whose opposite could have happened when this did. For this reason I did not say ‘something is contingent’, but ‘something is caused contingently’ ” (Scotus, op. cit., Wolter trans., quoted in Cross, op. cit., pp. 55, 56, 57, brackets in original).
In this admirably concise argument Scotus, using Latin Aristotelian terminology, packs together a whole series of claims about the first cause that are either completely un-Aristotelian, or not exactly Aristotelian. I’ll begin with a few global remarks, then address a number of details.
Very much unlike Aristotle, Scotus often frames his arguments as a kind of proof. This is a further accentuation of the strong emphasis on a kind of demonstrative science in the Arabic tradition that originated from al-Farabi. That theology should be such a science seems to be taken for granted in the Latin tradition of this period. (I think of theology as aiming to discern and elucidate a poetic kind of truth.)
Across the body of his work, Aristotle more often uses what might be called a hermeneutically oriented dialectic than the demonstration that is the subject of the Analytics. Aristotelian dialectic examines the inferential consequences of hypotheses. At the beginning of the Topics, he particularly singles out dialectic as appropriate for the discussion of first principles. Aristotelian dialectic aims at an open-ended wisdom, rather than exact knowledge. Rather than deductively expounding a preconceived system or an accomplished science in the manner of Euclid or Spinoza, Aristotle’s Metaphysics consists of a converging series of dialectical investigations. In the Nicomachean Ethics, he explicitly warns against making overly precise claims.
Aristotelian demonstration has the pedagogical aim of providing clear insight into reasons for adopting certain conclusions. The whole Arabic and Latin tradition, however, has it aimed instead at al-Farabi’s goal of demonstrative science. Such an approach aims to decisively prove that the conclusion is true, and it does so by making additional assumptions that are deemed to be reasonable. This too can be instructive as a kind of thought experiment, to see what can be achieved in this way.
But even though he never claims to eliminate dependence on assumptions, Aristotle himself continually works hard to minimize the role that assumptions play in his arguments. This is especially true for his arguments about first principles. Where first principles intersect with matters of religion, he seems to regard it as unseemly to claim too much. We should especially aim to minimize speculative assertions about ultimate matters, and this is a way of showing appropriate respect (as well as promoting peace and harmony in human society).
The great monotheistic religious traditions have often effectively taken the diametrically opposite stance, that it is virtuous to glorify God by making all possible maximalist claims about him. As many have recognized, this kind of theistic piety is profoundly un-Aristotelian. Rather than taking this as a ground for rejecting a stereotypical Aristotle as many have done, without wishing to offend anyone, in the ongoing work here I aim to help bring to light an unfamiliar and provocative Aristotle, for whom an open sense of wonder at the universe is more primordial, more enlightening, and indeed more theologically virtuous than maximalist praise of God. Moreover, I think the best praise consists not in any assertion, but in a more profoundly ethical way of acting.
Scotus speaks here of a first efficient cause. As I have discussed several times, the Latin concept of efficient cause is far removed from what in Aristotle’s text is called a “source of motion”. In Aristotle, the source of motion governs the character of the motion in question, in the way that the art of building governs the activity of building a house. In general, Aristotle inquires into activities rather than punctual actions. Aristotelian causes are not powers but ways of explaining things.
New readers may be surprised to learn that Aristotle himself presents the first cause not as an efficient cause at all, but rather as a final cause. That-for-the sake-of-which or the end is for Aristotle the way of explaining that comes logically first in the order of explanation. More elaborately, the first cause is entelechy, or an entelechy. What is first in itself, however, is not first in the order of our understanding.
It was the neoplatonic commentator Ammonius (5th-6th century CE), known for his accommodations to Christianity, who introduced the idea that the first cause is also what is now translated as an efficient cause. The notion of a first efficient cause effectively rewrites the order of causes in Aristotle to accommodate a theistic view. In Aquinas, for example, God’s creation from nothing becomes the paradigmatic example of efficient causality.
Scotus says that the first efficient cause directs its effort toward a goal. Having eliminated the Aristotelian teleology that is indwelling and primary, in company with many others he introduces a secondary, transcendent teleology that is more anthropomorphic in its operation. In this rendering, the first cause is said to knowingly aim at a goal it has chosen. Within the Arabic tradition, Ghazali’s Incoherence of the Philosophers — to which Averroes replied on behalf of the philosophers — had earlier similarly argued in effect that any teleology must depend on a being endowed with knowledge and will. Aristotle strictly avoids any language of that sort.
The division of action into action by nature and action by love is interesting. The introduction of love in a discussion of first principles is sometimes taken to be a Christian innovation. But Aristotle in the Metaphysics says the stars are moved by love of the first cause. Socrates in Plato’s Republic argues that all beings love the Good. Plato elaborates on the role of love from several points of view in the Symposium.
The way that Scotus explains natural action, it is strictly necessitated, but the whole order of nature is subordinated to a free cause. Again we see the interesting identification of free will with love. But the way that he mentions secondary causes seems to give them no role that is not already necessitated by the first cause.
When Aristotle speaks of secondary causes, it makes sense, because with Aristotle’s non-total first cause there is something for secondary causes to contribute to the whole. But secondary causes that are entirely necessitated by a first cause contribute nothing of their own, in which case the very mention of secondary causes is “in vain”, as the medievals might say.
All directing is said to presuppose knowledge. At the same time, it is emphasized that the Scotist first cause does not direct or cause in virtue of anything else. This is the first of several explicit statements insisting that the first cause must be understood as completely unconditioned.
Directing has the implication of control or command. The first cause in Aristotle does not control or command things, but works by inspiring the love that is motion toward a telos. The Good in Plato does not control or command things either; but all beings are said to love the Good. The more particular forms of this love of the Good, which characterize the striving of things, can be said to make them what they are.
Like Ghazali, Scotus insists that the first cause causes voluntarily and by will. He specifically invokes what contemporary scholars call synchronic contingency, which again is supposed to be completely unconditioned. The order of nature is again associated with strict necessity. The only alternative to strict necessity for Scotus must depend on something that is wholly unconditioned.
Aristotle’s nature does not operate according to strict necessity, but only according to a general determination that leaves options open. Because the first cause is a final cause, things are determined only generally, not in all their particulars. For example, animals must eat to live, but the particulars of which things they eat and when and how are not determined by this. Because there was never a strict but only a general necessity to begin with, freedom does not have to depend on something that is radically outside of nature.
Scotus criticizes the Arabic commentators for including humans in nature. This is an issue for him because the objective correlate, so to speak, of Farabian demonstration in natural science is strict necessity in nature. Like many Christian authors, Scotus objects to the inclusion of humans under strict necessity. Scotus apparently has no issue with strict necessity in nature, which he too asserts, but he subordinates that necessity to something radically unconditioned that he also sees at work in the human will.
Whereas in Aristotle himself necessity is not strict, and so freedom does not require anything radically unconditioned, Scotus instead seeks to explain everything in terms of two extreme poles of strict necessity and absolutely unconditional freedom. This same polarity will later be affirmed by Descartes — nature is to be explained mechanistically, but God and the human are treated voluntaristically.
