tatingly drawn in it is all too meagrely supported, and, although to be looked for in a series of lectures like the present, seems an intrusion in the context where it is found. The author apparently feels this, for he hastens on at once to other and I was about to say less controversial matters, but the assumption that his interpretation of history is the interpretation of Jesus would probably be as widely controverted.
The following passage summarizes the positions of the book and reveals the author's attitude and point of view with admirable clearness.
To give justice rather than to insist upon rights, to rely upon inner rather than outward moral control, to have every element of life expressive of the same spirit of love that God himself exhibits, and to regard love as not a desire to gain popular approval or even to get friends, but as a sacrificial determination to do to others as one would like to have others do to oneself—all this can be found as truly in any catholic reading of the facts of human history as in the words of Jesus. As has been repeatedly said, social evolution, conditioned as it is by the impersonal and economic world, is yet superior to that world. It is a spiritual movement which, if it be prolonged, will bring the world under the sway of the ideals of Jesus himself.
There has been considerable agitation of late for instruction in the history of science in our colleges and technical schools. This volume is a practical step in that direction.
The author has written a little book on a big subject in excellent English. Professor Libby's statement (p. 134), "Dr. Hutton presented his Theory of the Earth in ninety-six pages of perfectly lucid English", might well be applied to his own book, if we change the number of pages to 288. The style is condensed, but a pleasure to read.
How to approach the subject, how to organize the material, and how to present it to the reader, are problems which many of the longer histories of science have failed to solve satisfactorily. Professor Libby adheres roughly to chronological order, but his chapter-headings are topical. He discusses science as a whole and in the broadest sense, and does not as a rule consider the individual sciences separately. On the other hand, certain leaders of scientific thought and accomplishment are singled out, and their lives, personalities, and genius are entertainingly set forth. Perhaps another would not have chosen for emphasis just the names that the author has selected. English-speaking scientists, for example, seem to receive rather more than their due ratio of attention. But the author makes it clear enough that "science is international", and tells its story in a broad, human, and tolerant manner. Its relations to other fields of man's life—education, war, religion, industry, travel, philosophy, art, ethics, and democracy—are well touched
