Este artículo analiza la teoría humeana del conocimiento del mundo externo. Defiende que la misma supone una defensa del realismo directo propio del sentido común y una crítica de cualquier tipo de realismo representacional así como del fenomenismo. Esta defensa es escéptica porque Hume considera que la premisa básica de tal realismo, el carácter específicamente semejante de los cuerpos y nuestras percepciones de ellos, no tiene otro fundamento que la naturaleza de nuestra imaginación y, además, contradice la razón, a la (...) vez que señala que esta última facultad es incapaz de erigir un sistema preferible a aquel sistema vulgar.

Economists customarily talk about the ‘realism’ of economic models and of their assumptions and make descriptive and prescriptive judgements about them: this model has more realism in it than that, the realism of assumptions does not matter, and so on. This is not the way philosophers mostly use the term ‘realism’ thus there is a major terminological discontinuity between the two disciplines. The following remarks organise and critically elaborate some of the philosophical usages of the term and show some of (...) the ways in which they relate to economists’ concerns. In the philosophy of science, scientific realism is the mainstream position – or rather a heterogeneous collection of positions - that includes ideas about the nature of scientific theories and how they are related to the real world and about the goals and achievements of scientific inquiry. However, most of what philosophers have contributed around these ideas is not designed to deal with the peculiarities of economics, thus some important adjustments are needed to make scientific realism an interesting position for economists.
