The most prominent, yet almost the least known scientist in the world has at last overcome his aversion to publicity to permit a collection of various speeches and papers of his to be published in this book. It is avowedly an effort on the part of a friend to fore stall any misguided attacks on the personality of Einstein such as those to which most prominent men are subject. The purpose has been amply filled for we now have a record of his important acts and they reveal the character of the man as clearly as would a series of letters to his wife and closest friends.

Only a third of the book is devoted to scientific papers while the remainder of the volume is devoted to remarks on Zionism, Pacificism, and Philosophy. They show us a man whose sincerity is the only force strong enough to break the barriers of his modesty and is not wholly successful in that. For his modesty is present in even the scientific papers in which he gives credit to the work of his associates and predecessors and in this volume has even included a series of biographical sketches of the great scientists who, according to the author, have made his work possible.

His fluency, humor and occasional irony enhance the simplicity of language which is used in all except the most technical papers. As an enthusiastic Zionist he expresses a confidence in the future of the Jewish race and a pride in their history; as an opponent of war he shows a superior understanding of the political affairs of the world; as a philosopher he exhibits a complete knowledge of the writings of the classical authors and then continues to set forth a clear, simple doctrine of his own; as a man he shows a completely human character that can only add to one's estimation of him as a leading thinker of our time.

An altogether enjoyable and useful book, both as a reference and as a character sketch, which may be easily understood by any college man.
