It deserves to be in every family, and read and pondered, as closely relating to the highest moral and physical well-being of all its members.... The essential remedy for these great evils is to be found in Dr. Cowan’s work; therefore, may it be circulated far and wide.” WILLIAM LLOYD GARRISON. “As it is easier to generate a race of healthy men and women than to regenerate the diseased and discordant humanity we now have, I heartily recommend the study of THE SCIENCE OF A NEW LIFE to every father and mother in the land.” ELIZABETH CADY STANTON. “It seems to us to be one of the wisest, and purest, and most helpful of those Books which have been written in recent years, with the intention of teaching Men and Women the Truths about their Bodies, which are of peculiar importance to the morals of Society.... No one can begin to imagine the misery that has come upon the human family solely through ignorance upon this subject.”
