I have always tried to insist to men that they should do their duty to the women even more than the women to them.

Context

“Will you let me say, in the first place, that a woman who can write such a letter is certainly not "hopelessly dull and uninteresting"! If the facts are as you state, then I do not wonder that you feel bitterly and that you feel that the gravest kind of injustice has been done you. I have always tried to insist to men that they should do their duty to the women even more than the women to them. Now I hardly like to write specifically about your husband, because you might not like it yourself. It seems to me almost incredible that any man who is the husband of a woman who has borne him nine children should not feel that they and he are lastingly her debtors.” source
