Paul Horwich is a philosopher best known for his “minimalist” (or “deflationist”) theory of truth: that there is nothing more to the idea than that saying that something is true (“'Grass is green' is true”) is the same thing as saying it oneself (“Grass is green”). This view has met with little success, and now Horwich is dressing it in Wittgensteinian garb for resale. As marketing strategy goes, this isn't terrible – Wittgenstein's views are notoriously obscure, and his “quietism” has the same generally meta-skeptical tone as “minimalism” – but I'm not buying it, in neither the old guise nor the new.
Michael Lynch isn't buying it either. He too has a theory of truth (let's not get into it right now), and doesn't appreciate it being dismissed, not for its content, or his arguments for it, but merely for its being a “constructive” theory of truth in the first place. But it's hard to know whom to root for here, as Lynch's anti-Wittgensteinian remarks simply reprise the same trite, uncomprehending dismissals that philosopher has endured for nearly a century now. I won't have enough space here to say what Wittgenstein really meant, nor why he was right to say it; but it's important not to let these things go unchallenged.
Horwich begins by painting himself as the underdog fighting the good fight: “Apart from a small and ignored clique of hard-core supporters the usual view these days is that his writing is self-indulgently obscure and that behind the catchy slogans there is little of intellectual value.”
This is too stark a picture, not to mention a bit self-serving. It's not that there isn't such a clique, or such harsh rejection; but I'd identify at least two further gradations between idolatry and contemptuous dismissal. First, many mainstream philosophers recognize Wittgenstein's contributions, even without accepting (or understanding) his conclusions. More to the point, you don't have to be a “hard-core supporter” to share Wittgenstein's general attitude toward the tendencies in philosophy he objects to. I for one would be perfectly happy to leave Wittgenstein out of it entirely if I could get what I wanted some other way. But there are some things we need that only he gives us.
After some throat-clearing, Horwich boils his Wittgenstein down into four main claims (for elaboration see his recent book on the subject).
1. Philosophy is “scientistic” in aiming at “simple, general principles”.
Such principles, I take it, are fine for science, where no one is complaining about the abstract generality of, say, Newton's laws. But philosophy is not science. I'd agree with this part, except to point out that philosophy was aiming at such principles long before science came along. In fact science as we know it developed from what we used to call “natural philosophy”. More important than labels, though, is the fact that there's nothing wrong with either simplicity or generalization if they're properly understood.
