This article addresses some of the main streams of sociological analysis concerning the scientific system as a transmitter and/or producer of discrimination mechanisms. The issue of the minority presence of women is discussed relying on the so-called "classical" approaches to the sociology of science articulated by the American School and Bordieu's theory. These readings are set against the epistemological advantages offered by psychoanalysis. The issue of a socio-symbolic inscription differentiated as a function of gender shows the body to be a vector of différance (Derrida) expressing an imaginary system of filiation and genealogy, and which, in the Western world, finds one of its most fundamental incarnations as science.
