Such, then, is the abiding need of religion in a scientific age. To be scientifically minded is one of the supreme achievements of mankind. To love truth, as science loves it, to seek truth tirelessly, as science seeks it, to reveal the latent resources of the universe in hope that men will use them for good and not for evil, as science does, is one of the chief glories of our race. When, however, we have taken everything that science gives, it is not enough for life. When we have facts, we still need a spiritual interpretation of facts; when we have all the scientific forces that we can get our hands upon, we still need spiritual mastery over their use; and, beyond all the power that science gives, we need that inward power which comes from spiritual fellowships alone. Religion is indispensable. To build human life upon another basis is to erect civilization upon sand, where the rain descends and the floods come and the winds blow and beat upon the house and it falls and great is the fall thereof.

LECTURE III THE GOSPEL AND SOCIAL PROGRESS I Our last lecture started with the proposition that the dominant influence in the intellectual and practical activity of the modern age is man's scientific mastery over life. This present lecture considers one of the consequences of this primary fact: namely, the humanitarian desire to take advantage of this scientific control of life so to change social conditions that mankind may be relieved from crushing handicaps which now oppress it. For the growth of scientific knowledge and control has been coincident with a growth of humanitarian sentiment. This movement for human relief and social reform, in the midst of which we live, is one of the chief influences of our time. It has claimed the allegiance of many of the noblest folk among us. Its idealism, its call to sacrifice, the concreteness of the tasks which it undertakes and of the gains which it achieves, have attracted alike the fine spirits and the practical abilities of our generation. What attitude shall the Christian Church take toward this challenging endeavour to save society? How shall she regard this passionate belief in the possibility of social betterment and this enthusiastic determination to achieve it? The question is one of crucial importance and the Church is far from united on its answer. Some Christians claim the whole movement as the child of the Church, born of her spirit and expressing her central purpose; others disclaim the whole movement as evil and teach that the world must grow increasingly worse until some
