She was a very good-looking woman, and extremely intelligent. But she wasn’t really very female; she had too much of a male intelligence. - Friedrich Hayek

You cannot successfully use your technical knowledge unless you are a fairly educated person, and, in particular, have some knowledge of the whole field of the social sciences as well as some knowledge of history and philosophy. Of course real competence in some particular field comes first. Unless you really know your economics or whatever your special field is, you will be simply a fraud. But if you know economics and nothing else, you will be a bane to mankind, good, perhaps, for writing articles for other economists to read, but for nothing else.

I must confess that if I had been consulted whether to establish a Nobel Prize in economics, I should have decidedly advised against it.

The illiterate expression ‘given data’ constantly recurs in Lange. It appears to have an irresistable attraction to mathematical economists because it doubly assures them that they know what they do not know. It seems to bewitch them into making assertions about the real world for which they have no empirical justification whatever.
