"The task, bequeathed to us by Lenin, of creating a Logic (with a capital OLO), i.e. of a systematically developed exposition of dialectics understood as the logic and theory of knowledge of modern materialism, has become particularly acute today. The clearly marked dialectical character of the problems arising in every sphere of social life and scientific knowledge is making it more and more clear that only Marxist-Leninist dialectics has the capacity to be the method of scientific understanding and practical activity, and of actively helping scientists in their theoretical comprehension of experimental and factual data and in solving the problems they meet in the course of research."

This book traces the development of Dialectical Logic within the history of modern western philosophy, culminating in Marx s materialist dialectics. It brings out the essential contours of Logic through a detailed exposition of the ontological and epistem

Marxism is dialectical, Novack explains. It considers all phenomena in their development, in their transition from one state to another. And it is materialist, explaining the world as matter in motion that exists prior to and independently of human consciousness.

The achievements of science and technology during the past century are unparalleled in history.

Allegedly scientific theories are being used to "prove" that criminality is caused, not by social conditions, but by a "criminal gene". Black people are alleged to be disadvantaged, not because of discrimination, but because of their genetic make-up. Of course, such "science" is highly convenient to right-wing politicians intent on ruthlessly cutting welfare. In the field of theoretical physics and cosmology there is a growing tendency towards mysticism.

For the first time in centuries, science appears to lend credence to religious obscurantism. Yet this is only one side of the story.

The book presents an integral Marxist conception of the dialectics and methodology of scientific theoretical cognition, of the dialectical interrelation between the abstract and the concrete, of the unity of the historical and the logical, of the correlat
