Kant y el "círculo de los círculos"

The conceptual roots of the Hegelian dialectic are already presente in the Kantian transcendental philosophy, and especially in the Foreword to the first edition of the Critique of Pure Reason. This is the reason why one can speak about the Circle of circles in the context of the critical philosophy. Furthermore, the Kantian transcendental philosophy is the main conceptual background of every substantial direction of thought in the XX Century.
