Much can be said — and has been said — about the so-called “linguistic turn” in philosophy. For me it just signifies an overt recognition that all philosophic inquiry is constrained by the limits of language. The Buddha made the distinction between the moon we can each see, and a finger pointing at the moon. Language is the “finger” which essentially says “hey, look at the moon.” Once you see the moon, I can lower my hand, as it is no longer necessary. Philosophical discourse has as its aim the goal of seeing the moon together. The body of literature known as “Philosophy” is just an audit trail of the effort to come to see “what is” in a way that is satisfactory to both of us, at which point we can leave off until another day.

Did you notice what I did in the previous paragraph? I used language to talk about philosophy in general terms. I painted a word-picture of the process of doing philosophy and invited you to see it with me. If you bought into it, great. It was a linguistic exercise which required the imagination of both the writer and the reader to flesh out the intended meaning. It was “meta-philosophy” — philosophizing about philosophy itself. It was a “language game.”

The idea of philosophy as a language game comes from Ludwig Wittgenstein. Language games, for Wittgenstein, are more than just linguistic constructs: they also include players, moves, rituals, physical reality, etc. The scientific method carried out in a chemistry lab, for example, is a language game. The scientists, apparati, chemicals, procedures, data — even the scientific theories — are all part of the game. The “scientific method” structures the playing of the game, which has as its goal the pursuit of scientific knowledge. Even the notion of “scientific knowledge” is a linguistic construct that helps structure the game. The overall process of what goes on in a chemistry lab is a perfect example of a language game. Many parts of the game are not linguistic in nature (people, chemicals, beakers), but they are every bit as essential to the “game” as the linguistic elements.

To say that Philosophy is comprised of language games (and nothing more) is to “make the linguistic turn.” At the end of the day there are people, chess boards, moons, and beakers — these things exist. But when it comes to answering the question “what is Philosophy,” we are left with what we can say about what we can say about such things.
