Contradictions, from Consistency to Inconsistency
If something is contradictory, then it is not consistent; but if something is non-contradictory, is it necessarily consistent? If so, there may be nothing between consistency and inconsistency. Thus if we literally apprehend the title of this book, it will be on nothing. However, the title of this book should be understood more broadly. This is because it is not so obvious how we should deal with notions like contradictions, consistency, inconsistency, and triviality. It must not be the case that something is there and is not there at the same time - here is the principle of contradiction in the formulation of Aristotle which, on the one hand, forms the basis of all critical thinking, and on the other hand, it is the object of controversy among the philosophers from Heraclitus through Hegel, to the present day.
