The
science of eugenics is still young and much of its program must be
tentative and subject to the test of actual experiment. It is more
important that the student acquire the habit of looking at society from
a biological as well as a sociological point of view, than that he put
his faith in the efficacy of any particular mode of procedure.
The essential points of our eugenics program were laid down by Professor
Johnson in an article entitled "Human Evolution and its Control" in the
_Popular Science Monthly_ for January, 1910. Considerable parts of the
material in the present book have appeared in the _Journal of Heredity_.
Helpful suggestions and criticism have been received from several
friends, in particular Sewall Wright and O. E. Baker of the United States
Department of Agriculture.
