Upright men can even better convince themselves of the solid grounds on which the teaching of the Church in this field is based if they care to reflect upon the consequences of methods of artificially limiting the increase of children. Let them consider, first of all, how wide and easy a road would thus be opened up towards conjugal infidelity and the general lowering of morality. Not much experience is needed in order to know human weakness, and to understand that men—especially the young, who are so vulnerable on this point—have need of encouragement to be faithful to the moral law, so that they must not be offered some easy means of eluding its observance. It is also to be feared that the man, growing used to the employment of anti-conceptive practices, may finally lose respect for the woman and, no longer caring for her physical and psychological equilibrium, may come to the point of considering her as a mere instrument of selfish enjoyment, and no longer as his respected and beloved companion.
