may seek in vain in other countries. In Vienna, moreover, Professor
Freud, with his bold and original views on the sexual causation of many
abnormal mental and nervous conditions, and his psycho-analytic method
of investigating and treating them, although his doctrines are by no
means universally accepted, is yet exerting a revolutionary influence
all over the world. During the last ten years, indeed, the amount of
German scientific and semi-scientific literature, dealing with every
aspect of the sexual question, and from every point of view, is
altogether unparalleled. It need scarcely be said that much of this
literature is superficial or worthless. But much of it is sound, and it
would seem that on the whole it is this portion of it which is most
popular. Thus Dr. August Forel, formerly professor of psychiatry at
Zurich and a physician of world-wide reputation, published a few years
ago at Munich a book on the sexual question, _Die Sexuelle Frage_, in
which all the questions of the sexual life, biological, medical, and
social, are seriously discussed with no undue appeal to an ignorant
public; it had an immediate success and a large sale. Dr. Forel had not
entered this field before; he had merely come to the conclusion that
every man at the end of his life ought to set forth his observations and
conclusions regarding the most vital of questions. Again, at about the
same time, Dr. Iwan Bloch, of Berlin, published his many-sided work on
the sexual life of our time, _Das Sexualleben Unserer Zeit_, a work less
remarkable than Forel's for the weight of the personal authority
expressed, but more remarkable by the range of its learning and the
sympathetic attitude it displayed towards the best movements of the day;
this book also met with great success.[61] Still more recently (1912) Dr.
Albert Moll, with characteristic scientific thoroughness, has edited,
and largely himself written, a truly encyclopaedic _Handbuch der
Sexualwissenschaften_. The eminence of the writers of these books and
the mental calibre needed to read them suffice to show that we are not
concerned, as a careless observer might suppose, with a matter of supply
and demand in prurient literature, but with the serious and widespread
appreciation of serious investigations. This same appreciation is shown
not only by several bio-sociological periodicals of high scientific
quality, but by the existence of a journal like _Sexual-Probleme_,
edited by Dr. Max Marc
