This extraordinary plurality deserves some comment. First of all be it noted that the diversity is but skin deep. The cars, houses, wives, divorces, and psychiatrists of a Utah personalist do not differ from those of a New Hampshire Heideggerian or a North Dakota neo-Kantian, or even a Louisiana Austinian. The ideological differentiation, in formal philosophy, seems to mean nothing in the souls or life-styles of the philosophers, or indeed in the society which harbours and sustains them. Some of my best friends are American philosophers, but I should find it hard to deny that this seems to be the main corollary of the strange and characterless diversity: academic philosophic thought plays little or no real part in the wider intellectual economy of America.
