— Walter Lippmann"Because the results are expressed in numbers, it is easy to make the mistake of thinking that the intelligence test is a measure like a foot ruler or a pair of scales. It is, of course, a quite different sort of measure. Intelligence is not an abstraction like length and weight; it is an exceedingly complicated notion - which nobody has yet succeeded in defining."

I think there's a little more attention to human needs than to property rights. But I don't think much of political activism. It's so shortsighted. Most people are interested in their own personal comfort. I've said that about environmentalists. I think they care about bike paths and places to park their Volvos, not the planet as an abstraction.
