The moral and political philosophy of Abileah, a distinguished Israeli musician, is that of Martin Buber and Judah Magnes, one of reconciliation and nonviolence. He has made notable efforts, through proposals to the United Nations, through public appearances and appeals, and through the pattern of his own life, to promote Jewish-Arab concord and a Middle East (Israel-Palestine-Jordan) federation. But the political climate has offered no chance of tangible success. This is a sympathetic biography by an American professor who has been active in Quaker peace activities in the Middle East.
