I consider the treatment of the subject the most sane and practical that I know of, and therefore feel that I can conscientiously recommend the book most heartily. There is no subject so much hampered by ignorance, misconception and prejudice as that with which the book deals. I am sure the treatment of the matter will result in a more wholesome and healthful conception of the entire subject. — Dr. Henry F. Kallenberg, The Institute and Training School of Young Men's Christian Associations.
Chapter four naturally brings everything to a practical focus and seems to me admirable. Chapter five, too, impressed me as very useful. The topical questions and their answers in the appendix was a very happy thought and adds materially to the value of the book. — Dr. G. Stanley Hall, President Clark University.
I have gone through the book carefully and I am greatly pleased with it. I think it is admirably adapted to the needs and temperament of college men, and possibly all men. The topics discussed are of prime importance and interest for young men, the method of presentation is in all respects commendable, and the style is practical and concrete. The book ought to find its way into the hands of a great many young men. It should be in the hands of fathers and even mothers who have sons in the adolescent period. — Prof. M.V. O'Shea, University of Wisconsin.
I have no hesitancy in saying that it is by far the best presentation of this very important subject that I have ever seen. It answers many important questions for which I have seen no answer elsewhere. — Prof. William R. Manning, Purdue University.
I have heard the lecture and read the book and do not hesitate to recommend it. It is all that a young man needs to read to inform him of his duties and his perils in this matter. The ethical ideals are high and the advice sensible and wise. — Dr. Charles R. Henderson, Department of Sociology, University of Chicago.
