I recently re-read a classic piece by J.L. Mackie (April 1955), entitled “Evil and Omnipotence,” a stupendous philosophical essay about why theologians like Richard Swinburne are forced by their belief in an omnipotent, omnibenevelont and omnipowerful god into incredible and rather painful feats of mental gymnastics. One of Mackie’s minor points in the essay is that the so-called “free will defense” for the existence of evil in the world is problematic because the concept of free will itself is incoherent. Although, sometimes accusations of incoherence are thrown around a bit too easily in philosophy, I think this one has the potential to stick.

Attentive readers of this blog may have noticed that those who post comments to my entries often show two interesting and complementary attitudes: a fundamental distrust of (if not downright contempt for) philosophy, coupled with an overly enthusiastic endorsement of science. Take, for instance, my recurring argument that some (but not all!) of the “new atheists” engage in scientistic attitudes by overplaying the epistemological power of science while downplaying (or even simply negating) the notion that science fundamentally depends on non-empirical (i.e., philosophical) assumptions to even get started.

David Chalmers is a philosopher of mind, best known for his argument about the difficulty of what he termed the “hard problem” of consciousness, which he typically discusses by way of a thought experiment featuring zombies who act and talk exactly like humans, and yet have no conscious thought (I explained clearly what I think of that sort of thing in my essay on “The Zombification of Philosophy”).

There has been much discussion lately on this blog and elsewhere about the relationships among skepticism, atheism, and politics.

I like Penn&Teller, the magicians and debunkers of pseudoscience and general inanity. I regularly use clips from their show in my critical reasoning class, despite cringing every time Penn indulges in his “fuck this” and “motherfucker that” exercise in free speech (it distracts the students from the real point, not to mention the always lurking possibility of an administrator asking me about the appropriateness of foul language in a philosophy class).

Readers of this blog may begin to think that I have a personal antipathy for New York Times editorialist Stanley Fish. I don’t, really. Don’t even know the guy. And yet, somehow he manages to get criticized in writing by yours truly more often (and certainly more harshly) than Richard I-don’t-know-what’s-wrong-with-Bill-Maher-but-I’ll-endorse-his-award Dawkins.

The other day I went to a talk about the fall and revival of metaphysics, given by Sebastian Kolodziejczyk at the Graduate Center of the City University of New York. Metaphysics these days has a bad reputation, even among philosophers, so I was aware of its 'fall' but I was rather curious about the possibility of a 'revival'.

Being a skeptic is a rather lonely art. People often confuse you for a cynic, and I’m not using either term in the classical philosophical sense, of course.

Scientists are often assumed to be obsessed by definitions. After all, if you cannot precisely define a concept, say what a planet is, or what a biological species is, you literally don’t know what you are talking about, and how can you then possibly do science using that very same concept? And yet, the practice of science is very different, and to a surprising extent does not seem to depend on definitions of its objects of study.

A few days ago a local skeptic group here in Brooklyn organized a roundtable discussion on the concept of the paranormal. We thought this was going to be a chat about what people mean by that term, how one goes about investigating alleged cases of paranormal happenings, and so on.

We were in for a surprise. Turns out that a couple of real believers in the ghosts and the afterlife showed up, a somewhat rare opportunity to sit down with “the other side” and have a probing conversation to find out about what brings people to believe weird things.
