This work is written as a declaration of faith in the future of philosophy as a science. Professor Zardoya, with a very lucid analysis, shows us that the present and future task of Marxist thinkers is the struggle against the conceptions of the postclassical bourgeois philosophy. For this reason, we must thank the author for publishing this book, in times when these kinds of studies are hardly found in bookstores. Even when this is a specialized text, its reading may help to understand the true essence of Philosophy’s contribution to the interpretation of the convulsed world from the present day.
