Logic as semiotics implies, in the Peirce's point of view, a triadic structure of thought and sign, where the bipolarity constituted by the pair subject - object is overcome. Nominalism is surpassed and individualism too. Sign is broader than symbol and supposes potentiality and actuallity. Two classes of objects and two series of interprétants, each one of the least by its turn admitting a triple subdivision, give place to a logic of scientific conduct. This makes appeal to a future community whose belief corresponds to the Truth, and to a cosmologie dimension of thought that supplies with a ground to the last objectivity of knowledge and volition.
