Is Marxism a science? Flowers for Marx provides us an excellent window into this live debate, as it exists on the contemporary Left, through a series of essays that can roughly be split into two camps: Democratic Socialism as exemplified by frequent Jacobin commentators Matthew McManus and Ben Burgis, and a position somewhere between Marxist-Lenininsm and Third Worldism found in the authors Conrad Hamilton and Ernesto Vargas. For sure, these two sides differ on just about everything, from the question of continuity versus rupture between bourgeois society and any future socialism to the historical legacy of actually existing communism to their theoretical methods. Yet, strangely enough, the authors do have one thing in common: neither side seems to want to whole-heartedly defend the position that Marxism is, or should be, a science.
