Nevertheless, we can say in a general way that psychology is fundamentally a study of man in terms of functions and norms (functions and norms which can, in a secondary fashion, be interpreted on the basis of conﬂicts and significations, rules and systems); sociology is fundamentally a study of man in terms of rules and conﬂicts (but these may be interpreted, and one is constantly led to interpret them, in a secondary way, either on the basis of functions, as though they were individuals organically connected to themselves, or on the basis of systems of significations, as though they were written or spoken texts); lastly, the study of literature and myth is essentially the province of an analysis of significations and signifying systems, but we all know that this analysis may be carried out in terms of functional coherence or of conﬂicts and rules.
