My contribution has four parts. The first part deals with Kant’s theory of opposition, which comprises analytic, dialectical and real opposition. The second part is devoted to Hegel’s transformation of these three types of opposition into principles of the objective logic of reflection. In the third part, I offer reflections on Hegel’s theory of contradiction and in the fourth part, I offer some concluding considerations that link my topic to the overarching theme of ‘Thinking the thinking of false thinking’.
