A God for Science attempts to do for the scientist what Sertillanges' Intellectual Life did, so many years ago, for the committed intellectual: to help the believer, who in this case is also a scientist, to unity his life through a better understanding of ""the two-fold stream that nourishes him."" The first part of the book examines the conditions of that unity--the meaning of ""faith"" and ""science,"" the methodologies and competences of each, etc. The second part is concerned with achieving that unity, and proceeds by expanding the classic theme of finding God in the universe, and then develops that of the role of Christ in the cosmos. The final chapter examines the epitome of the synthesis which the author envisages as exemplified in the person of Teilhard de Chardin. Aubert claims that he had no intention of writing a book of apologetics; yet, almost inevitably, that is what he has produced. It is, however, an apologia with a difference: there is no dogmatism, no authoritarianism, no ""triumphalism."" But there is a good deal of common sense, a subtle persuasiveness, and an emphasis on human intellectual values that is new and refreshing. For all of that, theme and treatment are such that the book will be of interest only to the working scientist and, within that classification, only to the ""believing"" scientist.
