On the anniversary of Engels’ birth, we will highlight one of Engels’ greatest works, Dialectics of Nature. With his masterful grasp of dialectics, Engels pre-empted scientific discoveries like the equivalence of matter and energy and the role of labour in the development of modern humans. In this talk, we will show that modern science serves as a continuing validation of the Marxist method of dialectical materialism, revealing a world in a constant state of motion, flux and revolution. Our speaker, Ben Curry, is a leading activist of Socialist Appeal, the British section of the IMT.
