Marxist philosophy
The philosopher Étienne Balibar wrote in 1996 that "there is no Marxist philosophy and there never will be; on the other hand, Marx is more important for philosophy than ever before." So even the existence of Marxist philosophy is debatable (the answer may depend on what is meant by "philosophy," a complicated question in itself). Balibar's remark is intended to explain the significance of the final line of Karl Marx's 11 "Theses on Feuerbach" (1845), which can be read as an epitaph for philosophy: "The philosophers have only "interpreted" the world, in various ways; the point is to "change" it".
