Alan Chalmers citations

Alan Francis Chalmers, né en 1939 en Angleterre, est un historien des sciences et un épistémologue. Il s'est établi en Australie à l'Université . Puis, il a étudié la physique dans les Universités de Bristol, Manchester et Londres. Physicien à l'origine, il a été l'élève de Imre Lakatos et donc formé dans la tradition poppérienne.

Il est l'auteur de What is this thing called Science ? , publié en 1976, deux fois réédité, remanié et complété — 3e édition : 1999.

Il y passe en revue des critères utilisés dans l'histoire pour définir la science :



l'observation des faits, opposée à l'expérience — Poincaré avait aussi une réflexion sur le choix des faits intéressants.

la réfutabilité

les paradigmes

l'objectivité

le réalisme et l'anti-réalisme

les théories bayésiennes

le progrèsIl a écrit ultérieurement Science and its Fabrication , publié en 1990.

Dans ce deuxième livre, il rejette comme axiomatisation de la connaissance aussi bien le positivisme de Karl Popper que le relativisme de Paul Feyerabend, le premier parce qu'il contredit l'histoire des sciences, le second car il est incapable de démarquer sciences et pseudo-science.

Comme alternative, il propose de:



définir les sciences comme description uniforme du monde,

et afin de mesurer leur succès, de mesurer comment les sciences atteignent ce but.Il reste lui-même sur le progrès , mais sans voir le cercle du point de vue de la théorie marxiste de l'histoire : le progrès est le moteur de l'histoire, et la science en est une superstructure.

Tout comme Popper, il s'est intéressé aux critères de démarcation entre science et pseudo-science. Wikipedia
