The Cognitive Closure of Science. Case study_the Discourse about the Etiology of AIDS, 1981-1986

Abstract

As the sociology of scientific knowledge has revealed, research fields may legitimize frequently maintain oi hypotheses independently or in the absence of experimental data or other empirical evidence constituting conclusive scientific proof in accordance with declared rnethodological standards. This essay aims to show certain of the mechanisms and social factors that allow scientific discourse to function as a self-referential system, i.e., in an autonomous manner in regards to the border conditions of empirical experience, as described by W. Quine. I particularly concentiate here on how the organization of scientific work in selected disciplines can result in the local findings of individual laboratories being quickly transformed into unrevisable facts (black boxes). The phenomenon of the self-reference of scientific discourse is well illustrated by the case of the debate on the cause of AIDS. This discourse was so configured that by referring to one another and by theoretical imputation researchers caused the hypothesis on the causal relation between HIV and AIDS to begin to be accepted as an indisputable fact, even though the corroborating evidence had not appeared in the meantime.
