Education. (Originally published in 1861. New edition, with the author's latest corrections, 1906.) By Herbert Spencer.
This is the classic which marks an epoch in the personal development of every one who reads it, and which made an epoch in the history of education: the book was probably of more service to woman, owing to its liberation of girlhood, than any other of its century.
The Study of Sociology. (International Scientific Series. Originally published in 1873. Twentieth edition, 1903.) By Herbert Spencer.
This is, of course, the introduction to sociology, written for that purpose by a master, and in every respect a masterpiece. It contains many eugenic references and arguments. As far as the eugenic education of the adult is concerned, this is rightly the preliminary work.
Besides The Evolution of Sex and Mrs. Parson's book on The Family, there are many others relevant to the question of woman and eugenics, of which one or two may be noted here.
Sex and Society, Studies in the Social Psychology of Sex. (1907.) By W. I. Thomas.
This is a very readable and recent work, and for the general reader much the most suitable of any that I know.
Man and Woman. (Contemporary Science Series.) By Havelock Ellis.
A very clear and readable book.
