“Engels’s general leanings towards scientifc study produced a dichotomy between science and politics: “When one is a man of science, one does not have an ideal; one works out scientific results and when one is a party man to boot one fights to pull them into practice. But when one has an ideal, one cannot be a man of science…” (1). Circumstances prevented Engels from exercising his very considerable gift as a practical politician, living as he did in enforced isolation from the leaders of the SPD. Towards the end of his life, the growing electoral success of the Social Democrats led Engels to stress the evolutionary rather than the revolutionary side of Marxism and declare the tactics of 1848 to be outmoded in every respect.” (1) F.
