ABSTRACT. Sartre contends that if the intention is not a thing in consciousness, then the being of the intention can be only consciousness. Deleuze and Guattari note that the two forms of content and expression are in reciprocal presupposition, and they can be abstracted from each other only in a very relative way because they are two sides of a single assemblage. Lyotard claims that the rules of formation and linkage that determine the regimen of a phrase have to be distinguished from the modes of linking that stem from genres of discourse. Bachelard holds that sooner or later scientific thought will become the fundamental theme of philosophical polemics.
