Engels once called dialectics “the science of the general laws of motion, both of the external world and of human thought”.

It is the philosophy of motion and change. It was on the foundations of this philosophy that Marx and Engels developed their analysis of class society, of the rise and the inevitable fall of the capitalist system.

But motion and change are ubiquitous, not only to human life but also to nature as a whole. Everything from the evolution of species to the formation of our solar system is governed by constant transformation. To better understand the world in which we live, we must learn to apply dialectical materialism to all spheres of life, above all to the natural world.

This talk by Ben Curry focuses on the scientific philosophy of Marxism, dialectical materialism.
