Karl Marx took up the rallying call [of 19th Century progress], and applied his incisive language and intellect to the task of launching this major new and, as he thought, definitive step in history towards salvation—towards what Kant had described as the "Kingdom of God". Once the truth of the hereafter had been rejected, it would then be a question of establishing the truth of the here and now. The critique of Heaven is transformed into the critique of earth, the critique of theology into the critique of politics. Progress towards the better, towards the definitively good world, no longer comes simply from science but from politics—from a scientifically conceived politics that recognizes the structure of history and society and thus points out the road towards revolution, towards all-encompassing change.
