When Karl Marx said, in his eleventh “Theses on Feuerbach,” that “Philosophers have only interpreted the world in various ways; the point, however, is to change it,” he was not rejecting philosophy. He was articulating his ambitions for his own philosophical work. He was saying that the goal of his philosophy is to change the world.
Marx’s real obsession was practical politics, not philosophy. He was disinterested in the theories, discussions, and arguments that traditional philosophy is known for. His focus was on using philosophy to provide intellectual and moral support to the trade unionists, activists, and revolutionaries who were fighting for the socialist cause.
