for romance and,
without any evidence to support their day dreams, filled the blank
spaces left on their maps by unexplored tracts with amusing inserts such
as "Here there are lions."

Thanks to Freud's interpretation of dreams the "royal road" into the
unconscious is now open to all explorers. They shall not find lions,
they shall find man himself, and the record of all his life and of his
struggle with reality.

And it is only after seeing man as his unconscious, revealed by his
dreams, presents him to us that we shall understand him fully. For as
Freud said to Putnam: "We are what we are because we have been what we
have been."

Not a few serious-minded students, however, have been discouraged from
attempting a study of Freud's dream psychology.

The book in which he originally offered to the world his interpretation
of dreams was as circumstantial as a legal record to be pondered over by
scientists at their leisure, not to be assimilated in a few hours by
the average alert reader. In those days, Freud could not leave out any
detail likely to make his extremely novel thesis evidentially acceptable
to those willing to sift data.

Freud himself, however, realized the magnitude of the task which the
reading of his _magnum opus_ imposed upon those who have not been
prepared for it by long psychological and scientific training and he
abstracted from that gigantic work the parts which constitute the
essential of his discoveries.

The publishers of the present book deserve credit for presenting to the
reading public the gist of Freud's psychology in the master's own words,
and in a form which shall neither discourage beginners, nor appear too
elementary to those who are more advanced in psychoanalytic study.

Dream psychology is the key to Freud's works and to all modern
psychology. With a simple, compact manual such as _Dream Psychology_
there shall be no longer any excuse for ignorance of the most
revolutionary psychological system of modern times.
