?This book should be of interest to intellectually curious college students, non-scientific professionals, and all intelligent laymen although one short section, where Dr. Hildebrand uses his own researches in physical chemistry (an attempt to formulate a theory of solutions) to exemplify scientific thinking and action, may prove a bit difficult for readers with a non-science background. The major portion of the book, however, should be quite intelligible to the average reader. . . . Recommended for purchase by all libraries.?-Library Journal
