The Science of Logic is a true milestone in the history of Western thought. With this work, G.W.F Hegel founds a logic that goes beyond the conventional, that goes deep into the bowels of thought. Thus conceived, Logic becomes a new metaphysics: it lays the foundations of a systematically articulated idealist philosophy, which understands that only in universal reason is the substantial and true found.

In this book, Rafael Aragüés offers us a clear and accessible introduction to Hegel's masterpiece, which he presents as a first philosophy that underpins a whole system based on reason and freedom. Because the ultimate conviction of Hegelian idealism is that truth resides in reason's knowledge of itself, so that the rational and the free are, ultimately, the only two great themes of philosophy.
