252. (xvi) The first reason for legitimate separation is mental deficiency.
This is because conjugial love is the linking of minds; if therefore the mind of one goes in the opposite direction to that of the other, their link is dissolved and together with it their love fades. The faults which cause separation can be seen from this list. In the majority of cases these are madness, inflammation of the brain, unsoundness of mind, real stupidity and silliness, loss of memory, serious hysterical disease; such extreme simplicity that good and truth cannot be perceived; excessive stubbornness in failing to respect justice and equity; excessive pleasure in chattering and talking about nothing but insignificant and trivial subjects; an unrestrained desire to publish domestic secrets, or for litigation, beating, punishing, committing crimes, stealing, lying, deceiving, swearing; failure to take care of children, intemperance, extravagance, excessive prodigality, drunkenness, uncleanliness, immodesty, an interest in magic and sorcery, impiety, and many more. By legitimate reasons we do not mean legally accepted ones, but ones which offer the other partner a satisfactory reason. Separation from home too is rarely decreed by a judge.
