Abstract

It is our intention in this article to reconsider a text written shortly before his death by the founder of our Society, Pierre Delattre. In it he apparently proposed that the biological meanings of the word function were derived from the mathematical use of the word, a particularization.We claim, on the contrary, that it is the mathematical use of function that comes from its sociological and biological meanings. For this we go back to the etymology of the word. Function comes from the Latin verbfungi (in the first person,fungor). Fungor (a deponent verb form) already has a factitive meaning, I am made to do, and it applies to a functionary, a civil servant engaged in some specific social (or political, or military) task. Hence such a meaning presupposes the existence of a social structure able to compel individuals to undertake a specific task of common interest. The Latin verb can also be applied to a tool, made to function in the interest of man. Thus the meaning offungi requires a preexisting social or biological organization. The function aims to correct the dysfunctions of the global system, whether political or biological.
