Modern Researches in Logic of Concepts. Frege and Carnap

Summary/Abstract: The theory (or logic) of con-cept, one of the basic theories of classical formal logic, has been replaced in modern logic by predicate theory. The two do not exactly overlap, and the question that arises is whether the old theory of the concept cannot be revisited with the means of modern logic to be updated and adapted? For this purpose, I reviewed the contributions of G. Frege and R. Carnap in the matter of the concept, after which I tried to develop a new definition that could then be developed into a logical theory of the concept. In all these attempts I took into account the Fregean principle of separating the logical from the psychological, the objective from the subjective. The new defini-tion/theory gives us the possibility of a clearer demarcation between concept, preconcept and pseudoconcept, which, either in science or in current speech, are not very well demarcated.
