Minimal Truthmakers

22 May
May 22, 2012

I’ve been working on a paper on minimal truthmakers with an ex-colleague of mine from Durham, Donnchadh O’Conaill (we’ve previously written a paper together on monism). The paper is now at the stage where we could use some feedback. Rather than posting a link to the draft here, I’ll post this general call for volunteers — drop me a message if you think you might like to read it and could perhaps provide some feedback, or even just a general impression. We make some use of the work of Armstrong, Fine, Correia, Sider, and Schaffer, among others. The goal is to defend the usefulness of the notion of minimal truthmakers and to provide a definition of them, as well as give some reasons to think that there indeed are some minimal truthmakers. Our two primary arguments concern the explanatory value of minimal truthmakers, and the idea that at least ‘joint-carving’ (or fundamental) propositions are likely to have minimal truthmakers. The draft is about 8,000 words. The abstract is below.

A minimal truthmaker for a given proposition is the smallest portion of reality which can make this proposition true. Minimal truthmakers are frequently mentioned in the literature, and have been referred to as “of quite special importance for metaphysics” (Armstrong 2004, 19). However, there has been no systematic account of what minimal truthmakers are or of their importance. In this paper we shall clarify the notion of a minimal truthmaker for a given proposition, and argue that there is reason to think that at least some propositions have minimal truthmakers. We shall then argue that the notion of a minimal truthmaker can play a useful role in truthmaker theory, by helping to explain the truth of certain propositions as precisely as possible.

UNC-Chapel Hill Diaries #7

In Durham, they sell metaphysics by the pound. (Ninth Street)

In Durham, they sell metaphysics by the pound. (Ninth Street)

Firstly, I’ve got another batch of talks coming up. First of them is tomorrow, Friday March 30 at Duke University (3:30pm, West Duke 202) in the colloquium series. I’ll be talking about ‘Quantification and Ontological Realism’. The talk will be followed by a reception, so stick around if you’re attending. I’m looking forward to this one, as I think I’ve got a nice paper. It’s mainly a critique of Ted Sider’s recent defence of fundamental, perfectly joint-carving quantification in his Writing the Book of the World (OUP, 2011). It’s nice to go to Durham too, since they have a “Metaphysical Shop” and all (see the photo)… Ninth Street, which is relatively close to the campus, has a very nice selection of shops and cafes.

Already on the following Wednesday, April 4, I’ll be talking at Boulder, Colorado (3:30pm, HLMS 141) with the title ‘(Neo-)Aristotelian Essentialism’. I’ll be in Boulder April 3-5.

Other than that, I haven’t got much in terms of news. I pretty much missed the whole of last week being ill with a flu. Fortunately it only hit me after the party that I organized with Elizabeth at our place. The party went well, although the turnout could’ve been better — we’re a little bit out of the way and not that many people know me yet. It was fun anyway, with a good mix of Chapel Hill faculty and graduate students. We also had someone from another college in North Carolina, whom I knew from a conference. Oh, and Peter van Inwagen showed up too, which was nice! Unfortunately I don’t have any photographic evidence of the gathering, as I was too busy entertaining guests. I particularly regret not snapping a photo of the all-vegan buffet feast that we prepared with Elizabeth. A list will have to suffice: vegan sushi, seitan-tomato-onion skewers in jerk marinade, seitan-pineapple skewers in lime marinade with lime and cilantro dip, olive-walnut rolls, green salad with vinaigrette, hummus tray with veggies, olives, gingerbread cookies, and a chocolate-cherry cake. We made everything from scratch (except the hummus), so it was a fair bit of work! But very enjoyable, and people seemed to like the food too.

I ended up missing talks by Ned Markosian and Jonathan Schaffer at Duke last week because of the illness. Fortunately I managed to catch Schaffer at Chapel Hill. He gave a talk on ‘Structural Equation Models of Metaphysical Structure’ — not a very informative title. Effectively he revised his story about grounding a bit and suggested that it’s best understood as analogous to causation, or as “metaphysical causation”. I wasn’t convinced, but I won’t go into the details as I wasn’t able to follow the talk that well in my tired post-flu state. I might get my hands on a draft of this paper though (for the metaphysics reading group), in which case I’ll perhaps report in more detail.

Unsurprisingly, my running has suffered a big blow in March: I’ve missed two full weeks of training, with a half decent week in between. I’m back at it now, but still not up to full health. I’m running the Tar Heel 10-miler on April 21, so I’ve got another three weeks or so to get back into racing shape. Did I mention that I’m gaining weight from all the tasty craft beer and cooking and Elizabeth’s baking and… Well, maybe some of it is muscle from the gym work, who knows.

Deer, from our kitchen window

Deer, from our kitchen window

It’s effectively summer here now. Spring came and went with the cherry blossoms, and we even had a sweltering day of +31 Celsius not long ago. It’s nice and green everywhere. I hope to do a photography walk soon to capture some of that green stuff. The nights are warm enough to sit outside gazing the stars. Wildlife is still active too. There was some kind of an eagle on our backyard last week; I tried to photograph it but couldn’t get close enough to get a nice focus. Instead I managed to capture the Cardinal that you can see above, although it’s not the best shot — I’d really need a decent zoom lens for these birds. We also have woodpeckers visiting frequently, but they’re rather shy birds. I still haven’t gotten a better shot of the deer either, so I’m attaching one of my older shots of a couple that were hanging out around our house.

"Caribe", at Sage Café

"Caribe", at Sage Café

We haven’t been out in Chapel Hill or around much recently, but we did make another trip to Sage Café — a nice vegetarian restaurant quite close to our place. You can get almost everything vegan as well. This time I remembered to bring my camera and snapped a photo of my dish, Caribe — Caribbean style black beans topped with a slice of avocado, served with rice, grilled spicy tofu & plaintains. It’s not the cheapest place, but the food is quite tasty.

I’ll report back after Boulder, I think. A friend of mine from Finland is coming to visit right after though, and we’re planning to do a week’s road trip, so I’ll be away for a bit.

Summer School: Metaphysical Mayhem, Rutgers

06 Feb
February 6, 2012

This is a great opportunity for graduate students interested in hot topics in contemporary analytic metaphysics, Hosted by Rutgers University, taking place this May, and featuring some leading names in metaphysics!

Details copied from the Metaphysical Mayhem website.

Metaphysical Mayhem is back! Rutgers University will be hosting a 5-day summer school for graduate students May 14-18, 2012. John Hawthorne, Katherine Hawley, Ted Sider, Jonathan Schaffer, and Dean Zimmerman will lead the seminars on a variety of topics in metaphysics, including: natural properties, composition as identity, grounding, metaphysical explanation, and stuff like that…

We want the sessions to retain the dynamic of a graduate a seminar, and the seminar room is not large, so space is limited. Approximately ten graduate students from graduate programs outside the New York City/New Jersey area will be provided with room and board for the duration of the conference, hosted by Rutgers graduate students (in their homes or apartments). Subventions for travel may also be available. To apply for one of these ten slots, students should send an e-mail to Matthew Benton at mbenton@philosophy.rutgers.edu with the following attachments:

1. A brief (300-500 word) description of one’s interests in metaphysics.
2. CV
3. Unofficial transcript
4. A paper on any topic in Metaphysics

In addition, we ask that a professor familiar with the student’s work submit a very brief letter of recommendation (not more than a paragraph) to the same e-mail address (applicants should mention their references in the application e-mail).
The remainder of the participants in the seminar will be chosen from graduate students at Rutgers and at programs in the greater NYC/NJ area. Non-Rutgers students from local graduate programs should send the five items listed above to Matthew Benton, along with the name of a faculty member in his or her department willing to serve as a reference.

Lunch will be provided for all participants. Graduate students from NYC/NJ area schools will be responsible for their own accommodations and for most evening meals.

The deadline for applications is February 24, and participants will be chosen by March 9.

Publication: On the Common Sense Argument for Monism

21 Jan
January 21, 2012

This is a paper which I wrote with my former colleague at Durham, Donnchadh O’Conaill. I’ve mentioned it here before, but I thought I’d advertise it again since it’s now available in print! The paper is a chapter in a Palgrave-Macmillan volume edited by Philip Goff. The volume is in the Philosophers in Depth series and it’s called Spinoza on Monism. You can get the volume from Amazon.co.uk, among other places.

Philip Goff: Spinoza on Monism

Philip Goff: Spinoza on Monism

Our paper, called ‘On the Common Sense Argument for Monism’, is mainly a reply to Schaffer’s recent paper in defence of priority monism, which is also reprinted in this volume. We mainly take issue with one particular argument, the common sense argument, which Russell originally put forward in favour of pluralism, but which Schaffer turns on its head. We argue that the common sense argument for pluralism stands its ground. You can download the penultimate version of our paper here.

The list of contributors is impressive, including E. J. Lowe, John Heil, Jonathan Schaffer, and so on. The first part concerns monism in contemporary metaphysics, which is what our paper is about, and the second part is more historical, and more closely related to Spinoza. Here is the full list of contents:

PART I: MONISM IN CONTEMPORARY METAPHYSICS
Monism: The Priority of the Whole; J.Schaffer

There Is More Than One Thing; P.Goff
The World as We Know It; R.Healey
On the Common Sense Argument for Monism; D.O’Conaill & T.E.Tahko

PART II: MONISM IN SPINOZA
Spinoza on Composition and Priority; G.Guigon
Why Spinoza Is Not an Eleatic Monist (Or Why Diversity Exists); Y.T.Melamed
