Power and Act

I would say without hesitation that having a concept of power and act is better than not having one. Nonetheless, despite my tremendous admiration both for the work of Paul Ricoeur and for the classic developments of Leibniz and Spinoza, I think Ricoeur was mistaken to associate Spinoza, Leibniz, Freud, or Bergson with a properly Aristotelian notion of potentiality and actuality (see The Importance of Potentiality; Potentiality, Actuality). Ricoeur on several occasions in his late works identified Spinoza’s conatus, or the desire and effort of beings to continue being — as well as the appetite or desire of each monad in Leibniz, and desire in Freud — with potentiality in Aristotle.

I think Ricoeur was absolutely right to emphasize both the great value of potentiality and actuality in Aristotle and the generally salutary role of the other concepts mentioned, but I don’t think they are the same. Aristotelian actuality refers not just to a current state of things, but more profoundly to what is effectively operative in a process. In Aristotelian terms, I take notions like Platonic “power”, desire, or conatus to express aspects of this more profound, higher-order, and “dynamic” notion of actuality. This is all good as far as it goes, but such richer notions of actuality still do not give us true Aristotelian potentiality or its pairing with actuality, which I regard as an even greater treasure.

Potentiality consists in the concrete counterfactual conditions that give shape, generality, and a kind of substance or “thickness” to the determination of things in the present. It is always indexed to a specific actuality, supplementing and complementing it. It gives us an explicit way to talk about incomplete determination, multiple possibilities, and openness within that actuality, while still recognizing the reality of determination and concrete constraints. It helps us express real determination without overstating it. It is not itself a power, but rather what defines what our power can do.

Spinoza, in consistently following through his idea that there is only one substance, developed a fascinating relational perspective on things, but he strongly adhered to the early modern notion of a complete and univocal determination analogous to what is found in mathematics, which is ultimately incompatible with the Aristotelian notion of incomplete determination expressed in the idea of potentiality and actuality.

Leibniz’s notion of determination had a teleological as well as a mathematical component. He gave admirable consideration to variety, multiplicity, and alternate possibilities in the development of his thought. Nonetheless his notion of pre-established harmony seems to be a sophisticated variant of theological doctrines of predestination, according to which every tiny detail of the world’s unfolding follows from a divine plan.

A notion that each being has or is a kind of Platonic power is actually compatible with a notion of complete determination. For many years, this was the kind of answer I would have given as to how freedom and determination can be reconciled. In a view like this, the freedom of a being is explained in terms of its having a finite power and efficacy, and determination is explained in terms of how all the powers interact. (Leibniz of course denied real interaction, virtualizing it all into the pre-established harmony.)

In more recent years, I have wanted to stress instead that determination is real but incomplete. This is how I now read Aristotle and Hegel. Of all the major modern philosophers, it now seems to me to be Hegel who actually comes closest to recovering an Aristotelian notion of actuality and potentiality. Unlike Aristotle he does not explicitly talk about potentiality, but Hegel’s rich notion of actualization implicitly captures the nuances of the interaction of actuality and potentiality. (See also Aristotelian Actualization.)


When I talk about beings, or us as beings, I mean this in a very ordinary, pre-philosophical way. It seems to me that to informally qualify as a “being”, something must have a degree of coherence; a degree of resilience or persistence in the face of change; and relations to other beings.

We might form a notion of something absolutely singular or self-contained, but it would not be a notion of a being. The classic notion of something absolutely singular was the One of Plotinus, which for him explicitly preceded all being. For Plotinus, we should only begin to talk about being when we have something that is “both one and many”.

If we speak of beings, it makes some sense to inquire about the being of beings. To me, though, this just means a higher-order consideration of the ordinary “being a being” of ordinary beings. It does not imply some very different “Being with a capital B” that gives being to all ordinary beings.

When Aristotle inquired about “being as being”, he reached two main conclusions. First, “being is said in many ways”. That is to say, being is not a univocal concept; it has multiple meanings. More profoundly, what we nonetheless informally call being itself is itself analogous to something that is nonunivocal rather than univocal. The non-self-containedness that seems to be characteristic of beings means that if we look closely, what we call individual beings do not have univocal identity, but rather are “identified” by a kind of family resemblance to themselves. Beings do not have sharp edges that would unambiguously separate an inside from an outside, and sometimes they change profoundly. Second, being a being nonetheless always involves being some way that is distinguishable from some other way. Calling something a being or saying it “is” in any sense thus expresses a kind of commitment on our part, and as Aristotle and Brandom would both remind us, the very nature of commitments implicitly commits us to abstain from or correct other incompatible commitments.

Being a being in whatever sense thus involves both a determinateness and an openness. Determinateness and openness in turn have to be understood in ways that permit their coexistence. (See also Equivocal Determination; Openness of Reason; Bounty of Nature.)

I want to say that everything important about being a being belongs in the register of “whatness”, or what was traditionally called essence. Contrary to the great arguments of Aquinas as well as to the 20th century mystique of existentialism, I don’t find value in an allegedly separate register of existence. Some people have argued that Aristotle did not have a proper concept of existence, as if this were a shortcoming. I find Aristotle’s direction of our attention to the “what” of being to be noninflationary in a quite salutary way. (See also Substance; Platonic Truth; Meant Realities.)

Openness of Reason

In life, we most often do not really know what we are doing, but still, most of the time we find our way. This involves many small “leaps”, or actions on based on assumptions that we don’t actually know are true. These are unavoidable, they are “reasonable”, and most of the time they are harmless.

In forming views of the world, we need the maturity to distrust systematic unity or strong coherence as a supposed accomplishment, while still pursuing it as a goal. (See also One, Many; Unity of Apperception; Error; Foundations?; Interpretation.)

If we have a concept of Reason as something well distinguished but still fundamentally open in the last instance — which I find especially clear and well developed in Aristotle, Brandom, and Ricoeur — then we have no need ever for Kierkegaardian irrational “great leaps” or arbitrary founding decisions in the style of Badiou.
