Responsibility as Two-Sided

It is all too easy to judge others — to hold them unilaterally responsible for what we deem to be wrong. The saying “Judge not lest ye be judged” recognizes that there is something wrong with this.

I wanted to say a bit more about Brandom’s account of responsibility as inherently two-sided. This is related to the very simple — if uncommon — idea that there should be a correlation between the degree of one’s responsibility for something and one’s authority over it. This means that in ethical terms, no one has a monopoly on authority over anything, and no one is responsible for something without having some authority over it. Two-sided responsibility comes hand in hand with the sharing of authority.

In the Phenomenology of Spirit, Hegel develops an allegory of the softening of the heart of a hard-hearted judge. For Brandom in A Spirit of Trust, this allegory serves as a kind of climax of Hegel’s monumental work.

Traditional views commonly define morality in terms of obedience or conformity to authority. What we should do is simply given to us from an external source. Brandom calls this the authority-obedience model.

At least from the time of Socrates, those concerned with ethics have recognized that mere obedience or conformity is at best only a very rudimentary level of ethical development, and therefore the same must apply to naked authority.

In diametric opposition to the authority-obedience model, Kant famously emphasized autonomy as a necessary basis of morality. For Kant, we are only truly moral insofar as we genuinely think our judgments through for ourselves, rather than relying on external authority.

While fully endorsing Kant’s rejection of the authority-obedience model, Hegel criticized the Kantian alternative of autonomy as one-sidedly individualistic. It would be a bit arrogant to claim that we really did think everything through all by ourselves. Moreover, there is a kind of symmetry in the all-or-nothing attitudes of the authority-obedience model and the autonomy model. It would be more reasonable to acknowledge that most things in life depend partly on us and partly on something or someone(s) outside of us.

As Brandom reconstructs Hegel’s argument, Hegel wants to say that genuine moral responsibility is always two-sided. The hard-hearted judge in the allegory, moved by a lawbreaker’s sincere confession, confesses in turn that she too is not without fault. I think this applies even more clearly to conflicts and people’s judgments of one another outside a judicial setting.

The point is not at all to obliterate distinctions or impose an artificial equivalence between the actions of the participants. It is rather just to recognize that nothing of this sort is ever completely unilateral, and then to systematically take heed of this in real life.

Brandom and Pippin on Hegelian Ethics

Robert Brandom and Robert Pippin are two major “deflationary” readers of Hegel these days. Counter to the old bad stereotype of Hegel as an extravagant metaphysician who turned his back on Kant’s critique of traditional metaphysics, they both see Hegel as further developing the most essential aspects of Kant’s innovations. Both aim to carry forward Wilfrid Sellars’ Kant-inspired critique of the “myth of the given”. They both see human intentions in terms of shareable meanings rather than private mental contents.

Brandom sees Hegel’s notion of mutual recognition not only as leading to a radically new, expanded notion of responsibility, but also as providing a basis for a novel general account of the objectivity of knowledge. Pippin meanwhile has developed an innovative, strongly Aristotelian reading of Hegel’s practical philosophy. I like putting the two of these together.

Brandom radicalizes the Kantian theme of the primacy of practical reason, effectively putting ethical inquiry before epistemology, ontology, or formal logic. He replaces metaphysics with a new kind of meta-ethics. Unlike many who have used the term “meta-ethics”, he does not seek some naturalistic or empirical foundation for ethics; rather, he sees “normativity all the way down”. Normative considerations are involved in the interpretation of anything at all. Judgments of fact depend on value judgments, and value judgments implicitly depend on the possibility of dialogue under conditions of mutual respect. It is principally through being subject to open-ended rational dialogue that judgments are verified.

Brandom’s expanded notion of responsibility is aimed at promoting greater and wider forgiveness, while simultaneously eliminating common excuses for misdeeds. Aristotle and important strands of the Christian tradition already promoted the idea that people should not be blamed or punished for unintended consequences of their actions (or for things they were coerced into doing). Brandom attributes to Hegel the novel view that everyone shares responsibility for all unintended consequences.

Pippin makes the profoundly Aristotelian point that what we actually did is the best guide to what our intentions really were. He argues that for Hegel, our own interpretation of our intentions has no privileged status in comparison to the interpretations of others. He would undercut excuses of the sort “I did x, but I really wanted y“. Rather, he would say that what we really wanted — not in the abstract, but under all the conditions that actually applied — was just what we did.

The actuality referenced here is a matter neither of simple fact nor of empirical consensus or majority opinion, but is itself a matter of normative evaluation under conditions of rational dialogue and respect for all.

Actuality, Existence

I have been using the English “actuality”, following old standard translations of Aristotle. As with any Aristotelian technical term, in interpreting its meaning I try to rely on what the Aristotelian texts say about it, and to avoid importing connotations associated with other uses of the English word used to translate it. Aristotle’s Greek term is energeia, a word he apparently invented himself from existing Greek roots. Joe Sachs translates it as “being at work”, which I think is good provided “being” is taken in the ordinary sense that we transitively say something “is” at work, rather than taking “being” as a noun. The word is formed from the noun ergon, which in its root sense means “work”; the prefix en, which corresponds to the preposition “in”; and the suffix eia, which makes the whole thing into a noun, like English “-ness” or “-ity”. So, in the most literal sense, energeia means something like “in-work-ness”.

Even the literal sense is a bit misleading, because Aristotle is very clear that the primary reference of energeia is not to a present state or a factual state of affairs, but to a primitive or ultimate end, understood as a kind of fullness or achievable perfection after its kind.

We are not used to thinking seriously about achievable perfection, but Aristotle’s fundamental intention regarding “perfection” is that it not be out of reach of finite beings. The “perfection” Aristotle has in mind is not a godlike attribute of unqualified or infinite perfection, but rather something like what modern ecology calls a “climax state” of an ecosystem (like the exceedingly rich environment of a rain forest).

Ecological succession involves a series of states that lead to other states, whereas a climax state leads back to itself, as in Aristotle’s other related coined word entelechy, which Sachs renders “being at work staying itself”, and is literally something like “in-end-having”. An ecosystem in a climax state is maximally resilient to perturbation; it is more able to recover its health when something throws it out of balance.

When Aristotle speaks of “substances” persisting through change, it is not a simple persistence of given properties that he has in mind, but rather something more like a stable (i.e., highly resilient, not unchanging) ecosystem. Stability in ecosystems and populations comes from biodiversity, which is a modern scientific analogue of Aristotelian “perfection”. Diversity provides a richer set of capabilities. With respect to human individuals, the analogue would be something like a “well-rounded” character. In ethics, we could speak of a well-rounded pursuit of ends, in contrast with a narrow or selfish one.

Thus the concept of “actuality” in Aristotle has to do with a kind of immanent teleology or interpretation of things based on ends and values, which for Aristotle takes the place of what later writers called “ontology”, as a supposed fundamental account of what exists.

Some contemporary analytic philosophers have spoken of “actualism” as an alternative to the possible worlds interpretation of modal logic. According to the Stanford Encyclopedia of Philosophy, in this context “actuality” is simply equated with factual existence. Instead of making confusing claims about the reality of non-actual possible worlds, this approach locates alternate possibilities within the actual world instead of somehow alongside it. As far as it goes, I have some sympathy for this. But I want to resist some of the conclusions with which it is commonly associated, which follow from the very non-Aristotelian identification of actuality with mere factuality. (See also Redding on Morals and Modality.)

I said above that actuality in Aristotle’s sense refers to processes and states of actualization relative to ends and values, not just to present existence or the current factual state of affairs. Readers of Aristotle as diverse as Thomas Aquinas and Gwenaëlle Aubry are united in stressing the primacy of “in-act-ness” over mere factuality in the interpretation of “actuality”. Robert Pippin’s account of actuality in Hegel (see also here) in an ethical context spells out the consequences of this very nicely. I think Aristotle would endorse the views Pippin attributes to Hegel in this context.

Direct and Indirect “Knowledge”

For now, this will be the last installment on Alain de Libera’s Archaeology of the Subject. Though he has promised another four and a half volumes, I’ve reached the end of what has been published so far. Here I’ll briefly summarize the remainder of volume 3 part 1.

After analysis of an anonymous Averroist text of the 1270s that criticizes Aquinas in sharper language than that employed by Siger of Brabant, de Libera briefly discuses substance dualism and the plurality of substantial forms in the later Augustinian tradition. He documents the beginnings of the shift toward modern usages of “subject” and “object” in the 13th century. He notes the large difference in connotation between Aristotelian ousia and Latin substantia, glossing ousia as what something is in its depth. (I’ve been continuing to use “substance”, with Aristotle’s own gloss from the Metaphysics of “what it was to have been” a thing.)

He then turns to a long and delicately nuanced review of Aquinas’ compromise between Aristotle and Augustine on the soul’s knowledge of itself. The title of this chapter in French is a pun: by homonymy, it suggests “The Subject Supposed to Know Itself”, but literally, it is “The Subject Supposed to Have Itself”.

At summary level, Aristotle holds that all self-knowledge is indirect, while Augustine holds that the soul directly knows itself through its essence. But de Libera points out that there are elements of directness in Aristotle, and elements of indirectness in Augustine. He emphasizes that “knowledge” is said in many ways, from mere undifferentiated awareness to the strong knowledge that was called “science”. If we want to discuss claims about self-knowledge, we need to distinguish what kind of “knowledge” we are talking about.

In the final chapter, de Libera again mentions the Franciscan Peter Olivi, who in the 13th century criticized the representationalism of the medieval theory of “species” in the name of direct realism. Olivi also further sharpened Augustine’s claims that the soul directly knows itself by its essence. According to de Libera, while Olivi was far less influential than Aquinas, it was the interaction of their legacies that ultimately led to the modern notion of the human subject as agent and ego. Toward the end, de Libera again mentions the 18th century Scottish philosopher of common sense Thomas Reid, who was completely unaware of medieval Augustinian criticisms of representationalism, and re-invented direct realism.

Once again, we have to be careful about too easy assumptions regarding “isms”. Here, it turns out that both advocates of representationalism and advocates of direct realism may make strong appeals to immediacy and presence. The difference is that in modern terms, representationalists appeal to the alleged immediacy of mental representations, whereas direct realists appeal to the alleged immediacy of external objects. I read Aristotle as acknowledging a modest role for immediacy in common sense apprehensions, but as rejecting the idea that immediacy has any kind of privileged status in knowledge. I read Kant, Hegel, Brandom, and Ricoeur among others as strongly supporting this Aristotelian view.

Earlier, de Libera had noted a common Franciscan criticism that for both Aristotle and Aquinas, all self-knowledge is inferential. These days, I would take that as a compliment. In my youth, I uncritically absorbed a large bias toward immediacy myself. Immediacy was supposed to give a truth hidden by ordinary alienation. But in more recent years, I have become sympathetic to Brandom’s thesis that all apparently immediate knowledge is just that — apparently immediate, and that a kind of inference actually is the most primitive source of knowledge.

Taking Stock

I imagine the guiding thread of this blog as a sort of expanding spiral.

At the start three years ago, I had little thought of any audience, and treated it as a personal workspace like the many spiral notebooks that preceded it. I began by writing notes to myself, mainly on connections between my rather nonconformist reading of Aristotle and the work of the contemporary American analytic philosopher Robert Brandom, who among other things had convinced me to adopt much more favorable views of Kant and Hegel.

Already at the beginning, I expected to eventually include discussions like the posts of the past year. But it didn’t seem right to immediately plunge into deep historical details of the Aristotelian tradition, like I have been doing recently. I wanted to first begin to address the question “What is philosophy?”, not by directly asking it, but by example.

The first stage was to interleave capsule accounts of what I consider to be some of the great highlights of the history of philosophy with personal reflections on how this all relates to life. In a way I’m still doing this, but initially I remained closer to the trunk, so to speak. I’m now allowing myself to discuss some fairly esoteric historical questions, but still in the background am looking to what I regard as key moments or details in the history of philosophy for insight into what some have called the meaning of life.

As time has passed, I have also made more effort to explain things to possible readers, and to avoid wandering off on tangents. At the moment, I may be trying the patience of many with a lot of attention to neglected thought of the middle ages, but I hope I am providing enough clues to enable a thoughtful reader to begin to put together a much larger whole than I can encompass in any one post, through exploration of various links. I hope that at least for some, these seemingly esoteric details may turn out to have a larger relevance.

The Human in Siger of Brabant

Those whom modern scholars called Averroists were supposed to be unoriginal, dogmatic followers of Averroes. This turns out to be as inaccurate as the supposition that the Latin scholastics as a whole were unoriginal, dogmatic followers of Aristotle.

At issue here is what it is to be human, and in particular how the difficult Aristotelian concept of “intellect” relates to human beings. There were not just two but a wide variety of nuanced and well-argued positions on this.

Among the so-called Averroists, Siger of Brabant (1240-1280) is the best known name, but no full book has yet been devoted to his work. According to Alain de Libera, in his later works Siger developed original responses to Thomas Aquinas’ famous critique of Averroes.

Siger argued against Aquinas that the act of thought is not purely immanent but simultaneously immanent and transitive. That is to say, for Siger it is immanent in the human, but transitive in the separate intellect. While affirming a “separate” intellect, Siger emphasized against Aquinas that the total act of thinking is attributable to the whole human, and not just to the human’s intellective soul. Intellect is an “intrinsic operation” in the human that in a way does, and in a way does not, make it the “substantial form” and perfection of a material body. According to Siger, Aquinas’ claim that the intellective soul unequivocally is the substantial form of the body cannot be reconciled with Aquinas’ other claim that intellect as a power of the intellective soul is entirely independent of the body. Siger adopts Albert and Thomas’ term “intellective soul”, but for Siger only the animal and vegetative soul are united with the body in being. Intellective soul is naturally united with the body in operation but not in being, whereas Aquinas says they are united in being.

According to de Libera, Siger in his Questions on the Book of Causes argues that the form of the human is not simple, but is rather a composite comprising an intellect that “comes from outside” (in Aristotle’s phrase), and a vegetative and sensitive substance that is “educed from the power of matter” (de Libera, Archéologie du sujet vol. 3 part 1, p. 411, my translation). Intellect is said by Siger to be a “form subsistent in itself”. It is not a “substantial form” in the proper sense, which would imply that it was inherent in the human body. It is not in the body “as in a subject”. However, intellect has need of the human body (specifically, the phantasms of the imagination) as an object, and intellect is in turn attributable to the human as a whole, though it is not reducible to the biological organism. Intellect for Siger is neither the inherent form of the human nor a separate, external mover of the human, but a separate form with an operation that is intrinsic to the whole human, in which it participates by composition.

De Libera remarks in passing that the act of thought owes more to intelligible objects than to “intellect”. I would suggest that it is through language and culture and ethical practice that Aristotelian intellect “comes to us from outside”. We talking, encultured animals then acquire a spiritual essence that comes to be intrinsic to us, through our ethical practice, in which acquired intellect and animal imagination cooperate.

According to de Libera, for Siger “The ‘intelligent whole’ is composed of many psychic parts, which are not of the same nature, or of the same origin, or of the same ontological status” (p. 362).

Siger objects that Aquinas’ notion of intellect as united with the body in being “makes the act of thought a perfection of matter” (ibid). This makes the body intellect’s “subject of inherence”. But at the same time, applying Thomas’ own axiom that nothing is accomplished by a power separated from itself, Siger reproaches Thomas for being unable to account for “the integrality of the known” (p. 378), and specifically the knowledge of material things.

For Aquinas, establishing that there is an operation proper to the soul is essential to the possibility of the soul’s existence independent of the body, and thus to his philosophical argument for personal immortality. But Siger argues that in making intellect an operation proper (i.e., uniquely attributable) to the soul, Aquinas implicitly negates its attributability to the whole human. Intellection for Siger is “an operation common to the human composite as an integral whole” (p. 377). In other words, I think with my whole being, not just my “mind”.

De Libera concludes that Siger does preserve the possibility of personal immortality, which was a principal concern of Averroes’ critics. However, he finds that the texts do not support the claims of some recent scholars that Siger in his later works abandoned “Averroism” in favor of Thomism.

The phrase “form subsistent in itself”, according to de Libera, does not have the same meaning for Siger that it does for Thomas. Albert the Great had analyzed three logical possibilities for an “intermediate” kind of form that is neither fully separate nor inseparable from matter. According to de Libera, Siger’s work is consistent with this. Siger aimed at a mean between a Platonist excess of separation between form and matter, and what he perceived as a Thomist excess of union with respect to so-called substantial forms. De Libera does find, however, that Siger, like other authors, is too anxious to simplify the issues at stake, and that he goes too far in identifying the position of Aquinas with that of Alexander of Aphrodisias, who was regarded as having a “materialist” view of the human soul. He also says Siger goes too far in reducing Aquinas’ notion of form to the simple analogy of a stamp in wax.

De Libera meanwhile also raises doubts about Aquinas’ insistence on the absence of any intermediary between the intellective soul and the body. He notes that in a very different context, the Franciscan Augustinian Peter Olivi argued that the intellective soul is united with the body via the intermediary of the sensitive soul. Olivi’s position was rejected by the Council of Vienna in 1312.

De Libera accepts the notion of “substantial form” as genuinely Aristotelian, but appears to endorse the argument of Bernardo Carlos Bazán that Aquinas’ notion of intellective soul gives it a privileged ontological status that makes it more than a substantial form. According to Bazán, Aquinas’ anthropology from the very start goes beyond the Aristotelian hylomorphism that Thomas generally endorses. The form of a human in Aquinas — unlike anything in Aristotle — is such that it could not be the result of any natural generative process, but could only be created by God. Siger comes across as closer to Aristotle.

De Libera notes that in the wake of the English theologian Thomas Wylton (1288-1322), later so-called Averroists “invested massively” in a distinction between an inherent form and an assisting form, and regarded human intellect as an “assisting form”. (See also “This Human Understands”; “This Human”, Again; Averroes as Read by de Libera.)

Act and Action

Still pursuing roots of the modern “subject” in medieval Latin scholasticism by way of Alain de Libera’s Archéologie du sujet, I’ve reached the point where de Libera reviews Bernard Lonergan’s detailed account of act, action, and related terms in Aquinas. The most noteworthy conclusion is that Aquinas distinguishes “act” from “action” in opposite ways in different texts, when he combines it with his other distinction between cases of immanent and transient action. This confusion appears not to have originated with Aquinas himself, but rather with the Latin translations of Greek texts that he used.

In any event, the way these distinctions are deployed by Aquinas is to say the least highly fluid, which is to say that any attempt to interpret them univocally would result in contradictions. (Burrell, who considers the analogy of being a later development attributable to Cajetan, nonetheless suggests that there is an analogy of action in Aquinas.)

De Libera constructs a table of Latin terms (vol. 3 part 1, p. 325) used by Aquinas for the Greek energeia (literally “in-actness”, for which I’ve been using the conventional translation of “actuality”) in the agent and in an external product, respectively. Energeia may be actus in the agent and actio in the product, or vice versa. It may be operatio in the agent and either actio or factio in the product. It may be actio in the agent and factio in the product.

“What it is necessary to understand in this context is that for Aristotle it is one and the same principle that accounts for act, whether in the agent or the product. That principle is form” (ibid, my translation, emphasis added). According to de Libera, for Aquinas too form is the principle of both the act that remains in the agent, and that which passes to the product. (Burrell reads Aquinas in a relational way that avoids de Libera’s suggestion of something passing between agent and product. The idea of something passing between agent and product suggests Suarez’s later explanation of efficient causation by “influence”.)

De Libera takes note (pp. 327-332) of the Latin translation of the influential definition of praxis (ethical action or practice) in the treatise On the Nature of Man by the 4th century CE Syrian bishop Nemesius of Emesa used by Aquinas. In Greek, Nemesius says “praxis is energeia logiké“. The Latin translation by Burgundio of Pisa says “gestio is actus rationalis“. But the same translator rendered the same Greek sentence in The Orthodox Faith by the 7th century monk John of Damascus as “actio is operatio rationalis“.

This might seem like a complete muddle. But if we take act as form as the guiding thread as de Libera suggests, it may be possible to get something coherent out of it. On the other hand, some adjustment would still be required if we also accepted the identification of act with action and of action with an efficient cause. If act is supposed to be understood as form and end and action as the efficient cause or means by which an end is accomplished, then act cannot be identified with action.

It is one thing to recognize the limits of attempting to apply univocity and formalism in logic to the real world, and quite another to affirm a contradiction. But this is a quite delicate area, and sometimes there are arguments whether there is truly a contradiction or merely an implicit distinction between cases. The answer to this depends on interpretation, and every interpretation is subject to dialogue.

De Libera says that Burgundio’s translation of John of Damascus “introduces nothing less than the ‘modern’ vocabulary of action” (p. 327). Thus it seems that Aquinas ends up with an unstable combination of Aristotelian and “modern” meanings for act and action, but the instability was already present in the sources he used.

Roots of Action

Returning again to Alain de Libera’s Archaeology of the Subject, de Libera had characterized a typical modern view of human subjectivity in terms of a “subject-agent” that combines the notion of a grammatical subject with that of a cause associated with a kind of “intentions” that are considered to be both mental acts and representations. This is a very specific cultural construct that makes many assumptions. It has acquired a kind of common-sense status, but treating human subjectivity in this way is very far from universally valid.

The common cliché is to call this the “Cartesian subject”, but de Libera’s project is to show that the groundwork for it was actually laid within the Latin scholastic tradition.

My treatment of de Libera’s work has been and will be a sort of journey of discovery; I don’t know in advance exactly where it will end up.

I had begun to look at his treatment of the particular place of Thomas Aquinas in this development. Previously, I have approached Aquinas mainly in terms of his admirable recovery and defense of what I consider to be good Aristotelian principles, and what I take to be his simultaneous divergence from or confusion of some of these that I regard as highly important. So, I felt the need to consult a few sympathetic secondary sources for a view of Aquinas more on his own terms. Now I feel a little better equipped to resume this thread.

It was a commonplace of 20th century Thomism to recommend itself as an alternative to broadly Cartesian views of what it is to be a human being. The contrasting picture de Libera paints is far more intricate and ambivalent. As well as recovering Aristotelian insights, Aquinas took some new steps in a “modern” direction, but many of these were only consolidated by the systematizing efforts of later Thomists. Part of the reason I felt the need to dwell a little on Aquinas was to be better prepared to understand distinctions between Aquinas himself and later Thomistic developments.

“The semantic field of action is nonetheless more complex, its frontiers more porous, when one considers effective usage, the real implementation of the principles mentioned, or when one analyses more finely the lexicon of the authors” (Archéologie du sujet volume 3 part 1, p. 312; my translation).

To begin with, leading 20th century Thomist scholar Bernard Lonergan concluded that a simple distinction between immanent and transitive action is “too rigid” (ibid). Lonergan is quoted (ibid) saying it was later authors who considered it metaphysically irreducible. For Aquinas, agere (to act) has a strong moral sense related to what de Libera calls a “subject of imputation”. In medieval Latin, actio (action) is used to translate both Greek praxis (glossed as moral conduct) and poieisis (glossed as production). Lonergan says Aquinas uses actio sometimes in a general sense that includes both of these, and sometimes more specifically for moral conduct. By contrast, action affecting external matter is more properly called factio.

For Aquinas, actio in the moral sense, according to de Libera’s summary of Lonergan, is associated with “free beings who are masters of their acts” (p. 313). I (and I think Aristotle as well) would say instead ethical beings who are responsible for their acts. Freedom and mastery are here implicitly defined in terms of one another, and ethical being and responsibility are also defined in terms of one another.

As I understand it, Aquinas regarded the will as a function of intellect rather than a separate faculty, so he would not be a voluntarist in the technical sense formulated that way. Nonetheless, as I understand it, he insisted that humans have the equivalent of arbitrary freedom.

I say that responsibility does not involve mastery, nor does ethical being involve freedom to act arbitrarily. This issue is independent of questions connecting action with efficient causality.

Mastery and arbitrary freedom (medieval Latin libertas, or the liberty of the lord to do whatever) are (mis)applications of something analogous to omnipotence on a moral or social level. Early modern apologists for absolute monarchy were strongly committed to an analogy between absolute monarchy and theologies stressing divine omnipotence. For Plato and Leibniz, this was the formula of tyranny. (See also Euthyphro.)

Essentialism?

Is it reasonable to call a philosopher who makes significant use of “essence” or similar terms an essentialist? I would say no. If you look at the Wikipedia article on essentialism for example, it appears to be a term of superficial classification that is used in a hostile or pejorative way. The definition given there is certainly nothing I would identify with.

I find essence to be a very useful concept. This Latin-derived term doesn’t exactly capture any single word used by Plato or Aristotle. Essence is what I call a way of being rather than a thing or property. It corresponds to the more abstract meanings of “form” and “substance”, and to what Aristotle called the “what it is” and “what it was to have been” of a thing. For both Plato and Aristotle it is an object of inquiry rather than something taken for granted. Aristotle’s notions of potentiality and actualization apply to it concepts of alternatives, development, and unanticipated change.

Aquinas’ introduction of a separate explicit concept of existence is a good example of how meanings change with context. For Aquinas, God in the act of creation gives being to possible essences. This implies that the essences are completely preformed, as Leibniz argued explicitly. Leibniz’s pre-established harmony has been viewed as deterministic, though Leibniz argued that it was not. In any case, Aquinas and Leibniz treat essences as discrete possibilities, whereas I read Aristotle as focusing on what is actualized or subject to a process of actualization. Essence as a discrete possibility is still arguably more sophisticated than what gets called “essentialism”, but it is much closer. (See also Platonic Truth; Form Revisited; Form as Value; Form, Substance.)

Generalizing About the World

When I speak of things like “the goodness of the actual world”, this refers to life in general. It is not, for example, intended as an endorsement of the details of the social status quo.

Similarly, when I talk about finitude, I don’t have in mind some specific existing configuration of things, but rather the general principle that existing things are definite, while we are neither omniscient nor omnipotent.
