Dijalektika prirode

Although the work was not completed during his lifetime, its manuscripts and fragments were published posthumously, and the first Yugoslav edition appeared in 1950, in line with the then-current interest in the ideological and scientific foundation of Marxism in the natural sciences. In this work, Engels seeks to show that the laws of dialectics — the unity and struggle of opposites, the transition of quantity into quality, the negation of negation — are universal laws that can be applied not only to social relations and human history, but also to nature. Engels used the knowledge of the science of the 19th century at the time, so some of his claims are now outdated. However, the work still has philosophical and methodological value because it demonstrates an attempt to synthesize philosophy and natural science through materialist dialectics.
