Let me say right away that I don’t know how one becomes a philosopher. I can only speak about this in personal terms. Having studied philosophy for a lifetime, I suppose I can call myself a philosopher in the way others call themselves physicists or plumbers. Even then I hesitate to use the word. I generally avoid it when I am asked what I do for a living. Experience has taught me that there will be two possible responses. The first is: “Let me tell you my philosophy.” And the second: “So, what is your philosophy?” I find that I can only stammer in reply. After all these years I don’t know what “my philosophy” is. I certainly don’t want to pin some label on myself, saying that I am a realist, a materialist, a historicist, or whatever. And I certainly also don’t want to hear a catalogue of someone else’s dearest convictions.
