This book is interesting and a valuable addition to the already large volume of literature on this subject. It does not answer many of the questions which are raised, but this is doubtless a good thing, because these are questions that cannot be answered categorically and en masse but must be considered individually. The proper value of the book lies in the fact that it shows what these young people are thinking about and what questions they are asking one another and asking older persons who might be expected to answer them. It is a book that should be studied by parents, teachers and all young people. Physicians, ministers and social workers also should find it useful.
