Why Men Believe : The Groundwork of Apologetics. By the

Rev. Clement F. Rogers. (S.P.C.K. 2s. 6d. net.)—Professor Rogers has gained experience as a defender of Christian truth not merely by lecturing at King's College, but also by going out and facing the sceptic and the infidel in Hyde Park on Sundays. These admirable lectures consequently have a more practical tone than we find in much apologetic writing, and they deal frankly with real difficulties. The author begins with the psychological nature of belief, and then proceeds to consider the emotional, rational, and moral grounds for believing in Chris- tianity, concluding with a chapter on " The Claim of Authority," which is recognized in politics, in literature, and the arts and in natural science, and which cannot be wholly disregarded in religion. Professor Rogers emphasizes the value of common worship and the need for action in the Christian life. To the objector—whom he doubtless met in Hyde Park—who asks, What has Christianity done ? " and, like jesting Pilate, stays not for an answer, he replies that each generation has to learn ha lessons afresh, and that " if men repudiate Christianity, it can hardly be blamed for the consequences any more than can a doctor if men refuse to take his medicinm."
