Opposition and Circularity

From the middle of the twentieth century contradictory logics have been growing in number, scope, and applications. These are logics which allow for some propositions to be true and false at the same time within a given formal system. From psychology to physics one finds many examples of areas of the mind and of physical reality which exhibit an unmistakable degree of antinomicity. Quantum mechanics is a prime example. Now, it is commonly thought that antinomies depend essentially of negation. This is not so. In fact, there are many antinomies whose contradictory character is created by the fusing of opposite assertions into one. Indeed, antinomicity should be considered an instance of the more general notion of opposition. A logic of opposition is essential to deal with this general case.
