Criticism of the current psychological approach to logic. Ultimate assurance of the truth of the conclusion of any reasoning is faith in the governance of the universe by an Active Reason. The distinction between object of thought and the object thought about. The real object, unlike the object of thought, is not subject to the modifications of thought. Logic as general semiotic logic considers signs in general. Relationship among object, sign, interpretant. Signs as substitutes for objects and capable of interpretation through the mind. Nothing is able to represent itself exclusively.
