Wittgenstein comments that a philosophical problem has the form:  “I don’t know my way about.”  –So much in so little.

But I want now only to say this.  To feel the force of Wittgenstein’s comment, keep in mind that Wittgenstein is not lost in terra incognita; he is no stranger in a strange land.  He is lost at home.  He has to find himself, but to find himself where he is, where he has always been.  Everything around him is so alien and so familiar, so exotic and so everyday.  He is gone but he never left.

Sometimes the hallway to my living room becomes non-negotiable.  A philosophical problem has the form of homesickness in my easy chair.
