This chapter of the collective monograph consists of an analysis of the text Ethique comme philosophie premiere by Emmanuel Lévinas (1985). It aims to take the text as a substantial contribution to the questionning of the roots of science and religion and results in a serious thesis that an ethical demand is already present at the very heart of a congnitive act and that what we call the "objective reality" develops as a secondary projection - after the ethical relation has already been established.
