What does it mean that Contradiction is the Norm of Truth? Elena Ficara (Paderborn) Logic & Metaphysics Workshop

In my talk I argue for the thesis CT: contradiction is the norm of truth, and ask about its relevance for contemporary philosophical logic. I first present three positions in the history of philosophy that have advocated some versions of CT, namely Plato’s idea of the “dialectical gymnastics” in the Parmenides (Plato, Parmenides 136 B-E), Aristotle’s notion of dialectics in the Topics (Aristotle, Topics I, 2-3) and Metaphysics (Aristotle, Met III 1, 995 a 24-29), and Hegel’s contradictio est regula veri (Hegel Werke 2, 533), then derive from them some answers to the questions:

What is meant by “contradiction” in CT?

What is meant by “truth” in CT?

What is meant by “norm” in CT?

I will show that to examine the meaning of CT in historical perspective is useful to understand the seeds of genuine glut theories.
