"Dialectics is the science of universal interconnectedness...nothing more than the science of the general laws of motion and development of nature, human society and thought. Motion is the mode of existence of matter... There is no matter without motion, nor could there ever have been." Engles
"[Negation of the negation is a ] development that repeats, as it were, stages that have already been passed, but repeats them in different way, on a higher basis" Lenin, Karl Marx, July-Nov. 1914 CW, Vol.21, p.54
Thus to some it may seem that things have not changed but in fact they have.
