Conjugalia Praecepta

Plato admonishes old men to carry themselves with most gravity in the presence of young people, to the end the awe of their example may imprint in youth the greater respect and reverence of age. For the loose and vain behavior of men stricken in years breeds a contempt of gray hairs, and never can expect veneration from juvenility. Which sober admonition should instruct the husband to bear a greater respect to his wife than to all other women in the world, seeing that the nuptial chamber must be to her either the school of honor and chastity or that of incontinency and wantonness. For he that allows himself those pleasures that he forbids his wife, acts like a man that would enjoin his wife to oppose those enemies to which he has himself already surrendered.
