… I am now “Dr. Caret”! And what a relief it is. Many thanks are owed to my advisors JC Beall, Graham Priest, and Lionel Shapiro, faculty  mentors Michael Lynch, Don Baxter, Tim Elder, and Reed Solomon (maths) as well as classmates Aaron Cotnoir, Doug Owings, Nhat Long Vu, Rik Hine, Matt Clemens, Michael Hughs, and Jeremy Wyatt.

The Unreality of Logic August 22, 2009

Really amusing stuff. The context of the quote below is this: Richard Sylvan (Routley) describes the differences between, e.g. relevant and modal semantics as differences in the grain of the ontology, which can produce problematic results if we try to understand highly intensional functors (entailment and the like) through the crude modal framework. He goes on…

In hardline classical theory matters deteriorate still further, through assumption of a one world modelling; that the only world, or at least the only world that matters logically, is the actual world… This is backed up by familiar propaganda about logic requiring a robust sense of reality and the like. In fact it doesn’t; and shouldn’t.

More Blog Rankings July 5, 2009

Here is an interesting compilation of rankings of Top Philosophy Blogs. Amongst all of these rankings, we find that the Feminist Philosophers‘ blog and such Chinese philosophy blogs as Chris Panza’s and Manyul Im’s get top billing. This is quite impressive and does seem to point to the power of blogging in bringing attention to what are often minority sub-disciplines within the profession.

Circular Definitions May 17, 2009

I am reading the website for the UK Border Agency, trying to figure out how this new “points based” system works. In order to get Entry Clearance to work in the UK, one has to navigate the points calculator which gives a number of options for your migrant status. I want to know who applies under the respective categories of skilled worker, highly skiller worker, etc. The website has a section titled:

“You can apply under the highly skilled worker category now if you are:”

After which a number of bullet points, the last of which is below.

“applying for permission to enter the United Kingdom (known as ‘entry clearance’) under the highly skilled worker category.”

Helpful, no?

R.I.P. Bob Meyer May 6, 2009

Was literally just thinking to myself earlier today: “I should really see some of the great philosophers, like Bob Meyer, while they are still around.” Tonight I heard that Meyer passed away. Never knew the man so nothing personal to say, but I find his thought increasingly influential and his style enviable. I’ll just quote my favorite Meyer passage in tribute:

There is an intuitive parity between underdetermination and overdetermination with respect to a given [sentence]. This parity is wrecked by the paradoxes of implication. Overdetermination — [inconsistency] — triggers classically a psychotic break. Underdetermination — incompleteness – is by contrast relatively painless.”

The Divine Liar May 2, 2009

Consider the Divine Liar: it is possible for God to assert “I do not exist”. Whatever God asserts is true, so if God were to assert “I do not exist”, then God would not exist. In order to assert anything God has to exist, so if God were to assert “I do not exist”, then God would exist. Thus, if God were to assert “I do not exist” then God would both exist and not exist. So it is possible for God to both exist and not exist. But whether or not God exists, he does (or does not) necessarily. Thus, God both exists and does not exist.

What is Possible April 16, 2009

If we want to know what is possible, we can sidestep questions about the nature of possible worlds and jump straight to the question of their closure conditions. I accept that natural language utterances of “possibly…” are ambiguous between at least several senses: epistemic, physical, and metaphysical amongst them. Some philosophers think there is a sensible notion of “possibility in the broadest sense” which they sometimes equate with metaphysical or logical possibility. If there is such an all-purpose notion of possibility, I think we might do no better than the following suggestion at characterizing it.

Define a standard propositional language \mathcal L on signature \{\neg,\lor\}. Possibility in the broadest sense is equivalent to being true in some “broadly” possible world w where such a world is w\in\wp(\mathcal L) the sentence \alpha is true in w iff \alpha\in w . In other words, this is a highly elegant, simplistic, liberal, combinatorial conception of possibility in the broadest sense. Every set of sentences constitutes a possible world; what is possible is what is true in any such world. So what would be the compelling objections to this proposal?

 


Philosophy Ended and Begun Again April 7, 2009

Oh, stupid blogosphere, let me count the ways you have found to waste my time and energy. And yet, I must share the same with others. Here’s the entertainment for the day: David Brooks has a piece titled “The End of Philosophy” in the NY Times which hardly lives up to its incendiary title; he is fittingly refuted in, of all places, this web comic by Chaospet. Enjoy!

Philosopher’s Digest March 30, 2009

The Philosopher’s Digest looks like a great new site. In a nutshell, the aim of PD is to publish timely online reviews of recent articles in top philosophy journals. Reviewers include Berit Brogaard, Iris Einheuser, and Clayton Littlejohn amongst others. It looks like PD is just getting started (there are only a few reviews as of writing this), but I expect it will be quite a valuable resource.
