Birth Control, Mrs. Sanger claims, and claims rightly, to be a question of fundamental importance at the present time. I do not know how far one is justified in calling it the pivot or the corner-stone of a progressive civilization. These terms involve a criticism of metaphors that may take us far away from the question in hand. Birth Control is no new thing in human experience, and it has been practised in societies of the most various types and fortunes. But there can be little doubt that at the present time it is a test issue between two widely different interpretations of the word civilization, and of what is good in life and conduct.
