Report: Aristotelian Themes in Dependence, Modality, and Essence

27 Jan
January 27, 2013

It was a long day yesterday at the Aristotelian Themes in Dependence, Modality, and Essence Workshop, organized by Mika Perälä and me. We started at 9am and went on to 6pm with a few breaks. We had thought that the 1,5h slots for each of the five speakers would be quite generous, but it turned out that discussion filled pretty much all the time we had — a positive thing, of course!

Lucas Angioni (Campinas, Brazil) gave a talk on ‘Essence, Causality and Necessity in Aristotle’s Theory of Scientific Explanation’, followed by Michail Peramatzis (Oxford) with ‘Essence and Necessity in Aristotle’. Both of the morning talks were historical and we had a good audience of ancient philosophers (including Miira Tuominen, who clarified some of Lucas’s points for us). Michail’s talk was especially interesting for myself, since he has worked on priority in Aristotle and knows the contemporary literature on the themes of the workshop quite well.

My own talk on ‘Grounding Modality in Essence’ was perhaps too contemporary for this workshop, but I happened to have some slides for it from a previous occasion and it certainly fit the theme. Some good discussion followed in any case. Benjamin Schnieder (Hamburg) gave a more general talk on ‘Grounding and Dependence’, taking Schaffer as a foil and laying out the options regarding the connection between ontological dependence and grounding. Very interesting talk, and so clearly presented that I think non-experts were quite able to follow as well. Mika Perälä finished with a talk on ‘Aristotle on ouk aneu Dependence’, in which he explored the connection between the more general issues about priority in Aristotle with his own interests regarding thought and appearance.

We were all quite tired by the end — I should take the opportunity to thank the audience for their contributions and attention! Special thanks to my fellow founder of Dynamis, Jani Hakkarainen, who served as a chair (we announced The Finnish Network for Metaphysics just before my talk). We’d also like to thank the Academy of Finland and our Department for financial support.

Metaphysics as the First Philosophy

25 Aug
August 25, 2012

I recently posted the penultimate version of my ‘Metaphysics as the First Philosophy‘, forthcoming in a volume edited by Ed Feser: Aristotle on Method and Metaphysics (Palgrave Macmillan). I don’t think that Palgrave has officially announced the volume yet, but I guess I can reveal some of the other contributors; they include Robert Bolton, Stephen Boulter, David Charles, Kathrin Koslicki, David S. Oderberg, E. J. Lowe, Gyula Klima, and others — so it’s a pretty impressive volume! This is in Palgrave Macmillan’s Philosophers in Depth series. (I’ve also contributed to the Spinoza on Monism volume in this series.)

Aristotle talks about ‘the first philosophy’ throughout Metaphysics -– and it is metaphysics that Aristotle considers to be the first philosophy -– but he never makes it entirely clear what first philosophy consists of. What he does make clear is that the first philosophy is not to be understood as a collection of topics that should be studied in advance of any other topics. In fact, Aristotle seems to have thought that the topics of Metaphysics are to be studied after those in Physics. In what sense could metaphysics be the first philosophy in the context of contemporary metaphysics? This is the question examined in my chapter. Contemporary topics such as fundamentality, grounding, and ontological dependence are considered as possible ways to understand the idea of first philosophy, but I argue that the best way to understand it is in terms of essence.

Another, related thing that I wanted to mention. My Contemporary Aristotelian Metaphysics volume was recently reviewed in NDPR by Robert C. Koons, as I’ve mentioned. Koons briefly criticised mine and Lowe’s approach to metaphysical modality, noting that it may be closer to Plato’s than Aristotle’s. Alexander Pruss has developed an alternative approach to modality in his recent book, which Koons mentioned, but I can’t comment on that as I haven’t read the book (yet, it’s waiting on my shelf though). An observant reader (John) commented that this may not be quite accurate. John notes that In Book Theta there are suggestions to the effect that actuality is ontologically prior to capacity or possibility, and the line that myself and Lowe (and, of course, Kit Fine) take regarding the ontological priority of essence over modality doesn’t directly conflict with that.

I have a couple of things to say about this. I already mentioned something about this in comments, but I thought it would be useful to dedicate a post to the issue, since it’s quite central to my research. I discuss these matters, albeit briefly, in the first philosophy paper, and I’ve made use of relevant passages below.

Firstly, there is a certain tension between the idea that essence precedes existence (which entails that possibility precedes actuality), and what we see especially in the Posterior Analytics, but I believe that there’s an explanation to this, which is Aristotle’s peculiar conception of ‘species’, i.e. that they are eternal. From my discussions especially with Kathrin Koslicki and some others who know their Aristotle better than I do (like my colleague Mika Perälä here in Helsinki), it seems that it may not be unreasonable to revise the Aristotelian picture somewhat. This contrasts with the views of some Aristotle scholars. In a paper from the 70s (‘Essentialism and Semantic Theory in Aristotle’, The Philosophical Review 85:4), Robert Bolton suggests that, for Aristotle, knowledge of existence typically precedes knowledge of essence. Bolton’s case is based on his reading of the Posterior Analytics (especially 93a16–24). For instance, Aristotle discusses whether someone could know what a goatstag is, but denies that this is possible -– even though one may know what the name signifies -– since goatstags do not exist (92b4–8).

The reason why this may not be as serious as it first seems is that Aristotle holds only species to have essences (Metaphysics 1030a11–17); and, like I said, that species are eternal (e.g. Generation of Animals, 731b24–732a1). We can now see that, for Aristotle, there could never be an essence of a non-existent thing, such as a goatstag, for Aristotle thinks that there could be no such thing. Therefore, if we were to share the Aristotelian conception of species, we would indeed have to agree with him that there is no goatstag essence. Surely, only things that could possibly exist can have essences, and since there are no actual goatstags, Aristotle regards them to be impossible in this sense. Aristotle does not use these exact terms, but we can perhaps take Aristotle’s notion of actuality to correspond with what I am here calling existence. Similarly, my use of possibility roughly corresponds with Aristotle’s potentiality. Accordingly, we can formulate the idea at hand as follows: actuality precedes potentiality. It follows that this peculiar doctrine may be an artefact of the Aristotelian conception of species, although this brief analysis is hardly conclusive.

In his review of my book, Koons also makes the following claim regarding Aristotle’s position:

Epistemologically speaking, there is no clear priority in either direction. Instead, there is a dialectical interplay between our knowledge of the possible and of the actual.

In fact, I also subscribe to this view, at least if we specify it a little bit. That’s because I think that even though essence, or possibility, has ontological priority in individual examples, scientific and philosophical inquiry in general proceed in such a way that our knowledge of possibility is constantly being complemented by our knowledge the actual. I’ve described this process in my earlier papers on the relationship between a priori and a posteriori knowledge, and coined it ‘the bootstrapping relationship’.

Contemporary Aristotelian Metaphysics Reviewed in NDPR

09 Aug
August 9, 2012

The review by Robert C. Koons (University of Texas at Austin) is here. To my knowledge, this review at Notre Dame Philosophical Reviews is the first published review of my Contemporary Aristotelian Metaphysics volume. NDPR is no doubt the most prominent venue for philosophical book reviews, so it’s good to see this one published. There should be several reviews coming out in journals as well, but those may take longer to appear.

Koons doesn’t make many observations about the volume as a whole, but the review provides a comprehensive summary of each chapter, as well as some critical remarks on the individual chapters. The overall message is very positive though, here’s the opening paragraph:

In this collection, many of the leaders of the neo-Aristotelian movement in analytic metaphysics have contributed brief papers that point to emerging developments in the field. The book will be of interest to anyone who wants to stay abreast of the progress being made by this significant group. The collection is especially strong on the questions of methodology and ontological categories.

Regarding my own chapter, Koons points out that Alexander Pruss’ approach to metaphysical possibility in his recent book may be closer to Aristotle’s than my own (and Lowe’s). That may be true, but doesn’t bother me too much, as I never aimed to be completely faithful to Aristotle. Anyway, I admit that I haven’t read Pruss’ book yet, but I did recently get it and it’s on my reading list…

I expect that the review might boost the sales of the volume, which is why I’m alarmed that it appears to be out of print at Cambridge. There are copies available on Amazon.co.uk and Amazon.com, as well as a number of other online retailers, but we’ll see how long they last (get yours while you can!).

Tahko & Hofweber on the Foundations of Metaphysics

13 May
May 13, 2012

PhilosopyTV! Thomas Hofweber and myself discuss the possibility and foundations of metaphysics in the latest episode. We recorded the episode already some time ago, and I’m pleased to see that it’s now out. Thanks to David Killoren and the other folks at PhilosophyTV for making this happen.

These episodes are supposed to be fairly accessible, so we don’t go into a lot of technical detail, and have tried to avoid unnecessary jargon. To be honest, our discussion is just a brief glimpse into the very broad topic of the foundations of metaphysics — or metametapysics — but I hope that it’s of interest especially to those who may not be so familiar with the literature. For background reading, I recommend for instance Thomas’s ‘The Meta-Problem of Change‘ (2009) and my ‘In Defence of Aristotelian Metaphysics‘ (2012).

The discussion opens up with quite a long intro from Thomas, but I think it’s helpful. We then go on to discuss some more detailed topics, such as the status of mathematical objects, the epistemology of essence, and ‘esoteric’ and ‘egalitarian’ metaphysics — notions coined by Thomas.

I have to say that it’s not easy to have a discussion like this when you cannot see the other person (the video is recorded separately). What made it even stranger was that I was already at Chapel Hill at the time of recording, and we were in fact in the same building! Thomas was in his office, and I ended up using Simon Blackburn’s office. We had some technical issues as well, but the end result seems to work just fine (they did a good job with it).

Hope you enjoy it!
