Dialectical

I must not stay to notice the strange fortunes of all the many other quasi-human worlds. I will mention only that in some, though civilization was destroyed in a succession of savage wars, the germ of recovery precariously survived. In one, the agonizing balance of the old and the new seemed to prolong itself indefinitely. In another, where science had advanced too far for the safety of an immature species, man accidentally blew up his planet and his race. In several, the dialectical process of history was broken short by invasion and conquest on the part of inhabitants of another planet. These and other disaster, to be described in due course, decimated the galactic population of worlds.

Reason has long been declared the "harlot of the devil", and dialectical materialism a diabolical delusion.

It follows from the teaching of dialectical materialism about the knowability of the world that the laws of the development of social life are just as knowable as the laws of the development of nature.

Sure, maybe. We know — have long known — that romanticism and fatalism are dialectical lovers.
