“War and the Ideals of Peace,” is rather an abstruse study of the mental and psychological processes which form human character and lead to human action. It is mainly a discussion of the validity of the contention that recurrent wars are inevitable because man is governed by the inexorable laws of nature, which compel him to contend for dominance. The author admits that man is by nature a fighting animal, but contends that he possesses also “creative spontaneity,” and may by his own efforts mould and shape ideals that will enable him to triumph over the natural bent of his disposition. Thus individuals may be led in the ways and thoughts of peace and mould the policy of nations to peace rather than war. This is obviously true. It is shown in the history of nations, in the fact that through enlightened public sentiment many nations, especially during the past one hundred years, have been impelled to peace when there was temptation to war. The exceptions, when wars have occurred, have been due to the fact that enlightened public sentiment suffered a relapse or reversion and favored war. The antidote for war undoubtedly lies in developing the individual conscience, setting its creative spontaneity to work to formulate peace ideals—in short, to get the mass of men to think peace instead of war. Public sentiment is simply the superior weight of individual opinion, and if public sentiment is decisively for peace, the nation in which such public sentiment prevails will not go to war except to repel aggression. This leads us to a point of disagreement with the author of the book in his practical application of his theories to the correct policy for this country to pursue. That we should stand at all times for the principles of peace no right-thinking man will deny. But that to realize these principles it is the duty of this nation to disarm without a simultaneous agreement of the other great nations to do likewise, we emphatically deny. Dr. Marshall says:
