This volume Will show how the work of the monotheistic prophets acquired such solidity that the terrible blow Which Nebuchadnezzar dealt to Jerusalem failed to destroy it. By a miracle of faith and hope unparalleled in history, the Iahveists of the prophetic reformation disseminated along the banks of the Euphrates Will bring about the return to Judea, the re-establishment of holy Wor Ship, the rebuilding of Jerusalem. I hope that I may be given the strength to delineate, in a fourth volume, the train of J ewish ideas up to the appear ance of Christianity, and thus to complete the cycle of religious history Which I have taken as my task. It is a hope Which I scarcely ventured to nourish a few years ago. I now think that I may Without presumption look forward to the completing of the Work Which has been the principal aim of my life.
