To reject them is to adopt the attitude of one who stubbornly insists on traveling by stage-coach, though having at his disposal a train or airplane ... The great philosophers of the past did not rely exclusively on those weak logical tools left to them by their predecessors. The very problems themselves and their own scientific genius forced them to build rational reconstructions that went far beyond those of their time.
