472. IX. THAT WEIGHTY CAUSES ARE REAL WHEN BASED ON WHAT IS JUST. For the knowing of these causes, it suffices to recite some that are real, such as an absence of parental love and the consequent rejection of infants; intemperance, drunkenness, uncleanness, shamelessness; proneness to divulge the secrets of the home, to quarrel, strike blows, take revenge, do evil, steal, deceive; internal dissimilitude causing antipathy; a shameless demand for the conjugial debt whereby the man becomes a cold stone; addiction to magical arts and sorceries; extreme impiety, and other like faults.
