Abstract

The category of« organism » has an ambiguous status: scientific or philosophical? In any case, it has long served as a kind of scientific « bolstering » for a philosophical train of argument which seeks to refute the « mechanistic » or « reductionist » trend, which is seen as dominant since the 17th century, whether in the case of Stahlian animism, Leibnizian monadology, the neo-vitalism of Hans Driesch, or, lastly, of the « phenomenology of organic life » in the 20th century, with authors such as Goldstein, Straws, and Weizsäcker, whose influence on Merleau-Ponty but also Canguilhem is obvious. The aim of this article is both to bring to light the sedimentation of this category and to give a critical evaluation of it, in other words, to sec in what way it might still be useful once one has eliminated the possibility of any « organicist » excesses. I suggest a notion of organism as an instrumental fiction.
