This paper reconstructs the ways in which metaphors are used in the text of “The Wealth of Nations”. Its claims are: a) metaphor statements are basically similar to those in the “Theory of the Moral Sentiments”; b) the metaphors’ ‘primary subjects’ refer to mechanics, hydraulics, blood circulation, agriculture, medicine; c) metaphors may be lumped together into a couple of families, the family of mechanical analogies, and that of iatro-political analogies. Further claims are: a basic physico-moral analogy is the framework for (...) Smith’s psychological theory as well as for his overall social theory and for his theory of market mechanisms; a iatro-mechanical analogy is as pervasive as the physico-moral analogy and provides the framework for his overall evolutionary theory of society; the invisible-hand simile relies on the physico-moral analogy, and elaborates on the role of vis attractiva and vis a tergo in mechanics.

Recent contributions by Kuhn, Wartofsky, and Granger, converge in the direction of an extended view of models, one that acknowledges a metaphorical dimension in the language of science. Such a view is in some respects the opposite of the views of both Bachelard and the Logical Empiricists. A number of familiar puzzles of the philosophy of science, such as the problem of reference, the opposition of realism and instrumentalism, that between explanation and understanding, and the status of scientific objectivity, may (...) receive a new solution in the light of the Kuhn/Wartofsky/Granger view of scientific metaphors.
