Causes of love, of friendship, and of favor between consorts (1586-1640 [CL 180, 214, 290]).

While there is love between consorts, there is also friendship and favor (1588-1590 [CL 180, 214, 290]).

If between consorts there be not spiritual conjugial love, there still may be friendship and favor: and if there be not friendship between them, there still may be favor, that is, the civility of moral life (1591-1591 [CL 278, 287-293]).

An internal or spiritual cause of conjugial love and friendship is true religion (1595-1597 [CL 238, 239, 531]).

And that both have the same religion (1598-1601 [CL 242]).

Also that from religion adulteries be shunned (1602-1606 [CL 147-149]).

An internal and spiritual cause of conjugial love is similitude of souls and of minds; and an external or natural cause is similitude of manners and of state and condition in society (1606-1608 [CL 246, 250]).

An external or natural cause of love or friendship between consorts is potency (1609, 1610):

Also abstinence from whoredom, from any cause excepting impotency (1611-1614).

There is also indifference on the part of the wife to the acts of Venus; and from this, and sometimes from a turning of the back, the husband is persuaded that his wife is without any desire for those acts (1615-1617 [CL 259, 294]).

There is also the love of infants and children, common to both (1618-1622 [CL 284, 404, 409]).

There are with each partner, industry, assiduity and intelligence, in their duties; and in some of these there is mutual assistance (n 1622-1624 [CL 164, 165, 176, 283]).

There is also prudence in conforming to the nature and genius of the other (1625-1627 [CL 282, 294]). Inequality in worldly things that are loved, sometimes conduces to love or to friendship between partners (1628-1633 [CL 287]).

A cause of apparent favor, as friendship or as love, is the love of peace in the house, and a love for reputation outside of the house (1634-1637 [CL 285, 286]). A cause of apparent favor, as friendship or love, is, that the wife does not cease to favor her husband when his potency ceases. This favor may become love when they grow old together (1637-1640 [CL 290]).
