 Though Royce lived only a few years beyond this late philosophical breakthrough, his last period brought the true culmination and flowering of his life’s work. Besides The Sources of Religious Insight and The Problem of Christianity, notable available works include The Hope of the Great Community, his last Harvard seminar on Metaphysics (1915–16) and a series of lectures given at the University of California at Berkeley. These lectures at his alma mater were to have ended with a talk entitled “The Spirit of the Community.” When the Great War broke out, Royce set this manuscript aside and sketched a practical proposal to use the economic power of insurance to mediate hostilities among nations and hence reduce the attraction of war in the future. War and Insurance (1914) was a daring political and economic proposal on behalf of the Universal Community.
