Hegel's dialectic was on its head, believing that the material world was a reflection of a 'Universal Idea' or God. Marx explained, on the contrary, thoughts and ideas were simply the reflection of the material world. So Hegelian dialectics were fused with modern materialism to produce the higher understanding of dialectical materialism. These laws of dialectical materialism were able to explain things in their development and motion. Whereas formal logic was essentially the logic of lifeless, rigid and static relationships, dialectics was precisely an understanding of real life-processes of motion, contradiction and change.
Dialectics is the logic of evolution, movement, and change.
Its starting point is reality itself. Each one is organically linked to the others. These laws, however, are not all-embracing and eternal. To think otherwise is to contradict the spirit of the dialectic. We have already noticed that dialectical thought had its basic origins 2,000 years ago, were systematically developed by Hegel, and then further deepened by Marx and Engels.
