I learned from my illiterate but wise mother that all rights to be deserved and preserved came from duty well done. Thus the very right to live accrues to us only when we do the duty of citizenship of the world. From this one fundamental statement, perhaps it is easy enough to define the duties of Man and Woman and correlate every right to some corresponding duty to be first performed. Every other right can be shown to be a usurpation hardly worth fighting for.
