My Dear Friends
Dr. Morton Prince and Dr. John Madison Taylor
Who have kindly encouraged me in the publication of this essay.
Revered Master, William James,
You who have urged me during the dark hours of
the Spanish-American War to write on Social Psychology,
foreseeing the great dangers that threatened humanity,
now that your worst fears of the misery of mankind have
come to pass, to you I offer my belated tribute.
