Now the Eugenic moral basis is this; that the baby for whom we are primarily and directly responsible is the babe unborn. That is, that we know (or may come to know) enough of certain inevitable tendencies in biology to consider the fruit of some contemplated union in that direct and clear light of conscience which we can now only fix on the other partner in that union. The one duty can conceivably be as definite as or more definite than the other. The baby that does not exist can be considered even before the wife who does.
