Certainly, the categories posited by a general semiotics can prove their power insofar as they provide a satisfactory working hypothesis to specific semiotics. However, they can also allow one to look at the whole of human activity from a coherent point of view. To see human beings as signifying animals — even outside the practice of verbal language — and to see that their ability to produce and to interpret signs, as well as their ability to draw inferences, is rooted in the same cognitive structures, represent a way to give form to our experience. There are obviously other philosophical approaches, but I think that this one deserves some effort.
