----------------- HES POSTING ----------------- A _locus classicus_ for a quote about `economics and engineers' is Pigou's admonition ``While it is natural and right in the present deplorable state of the world's affairs that many economists should seek to play a part in guiding conduct, that is not their primary business. They are ... engineers, not engine drivers.'' (Theory of Unemployment, 1933, p.v, preface). In a recent book (Gerhard Michael Ambrosi: Keynes, Pigou, and Cambridge Keynesians (Palgrave Macmillan: Houndmills, Basingstoke etc.) 2003, pp.30-31), I argue that this passage is a derogation of Keynes and his _Essays in Persuasion_, re-published in 1930 - and, of course also of Keynes' intensive advisory committee work around that time.
