Philosophers have only interpreted the world, in various ways. The point, however, is to change it, says one of the theses, stipulated by Karl Marx and Friedrich Engels in 1845. Humanity took them at their word: they waged wars, erected walls, winded up fences — all in the name of change. Yet, here we are again, over 170 years later, still waging wars, erecting walls, winding up fences. Maybe Marx and Engels were not right after all. Should we perhaps not start with ourselves, before tackling the world?
