Dr. William Brown writes a Foreword to this little book in which he says: 'I have read the book through with interest and with general agreement, and can confidently recommend it to the non-medical public for whom it is intended' (pp. vii–viii).

On turning to the pages on psycho-analysis we read that '"Psycho-analysis" is not only a method of treatment devised and employed by Freud and his followers, but the name also stands for a very definite school of psychology whose adherents demand complete infallibility' (p. 14). This completely silly utterance, which we hope is to be excepted from Dr. Brown's approval, does not instil respect for the author's balance of judgement. Nevertheless, in moments when he is less dominated by the uprush of unknown influences he has much that is sensible to say on the main theme of the book.
