El lugar de la verdad en un mundo de evidencias:: La retórica de las ciencias biomédicas

Abstract

This article develops some aspects o f the notion o f evidence or p ro o f
in the so-called biomedical Sciences, emphasizing that they constitute
communities o f methods rather than o f truths. The notion o f truth in an
absolute sense is absent from the scientific discourse and is replaced by
the vague term “evidence ” in its least concrete connotations. This means a
displacement from goals or ends o f knowledge to the means which permit
its construction. Some implications o f this scenario indícate the need o f a
dialogical perspective in the social construction o f knowledge aasociated
with the professions related to health and healthcare.
