Abstract
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 antinomy between 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
