It is the author's belief that the urgently required integration or interpenetration of sociology and history will not come about until intellectual tools, and that these tools will, as in the past, be furnished not by specialists themselves but by philosophy. The fact that que are nowhere in sight of such a consummation is no reason for dismissing its coming as improbable. In any case, it is along these lines that progress sould be looked for. And with this final fling at the reigning empiricist orthodoxy, the author retires from the stage and rings up the curtain.
