A sane man will propose to a woman for her intelligence (= ability to give birth to intelligent children and the ability to raise them well), education (= cooking, sewing, philosophy, and musical skills) for her long hair, wide hips, and big breasts (=her fertility and ability to give birth to many healthy children), for her (inner and outer) beauty (= mental and physical health), as well as for her youth (= fertility and ability to give birth to and raise many children).

When her physical beauty fades, her inner beauty magnifies, and yes, he keeps finding her attractive. She is the good mother of his children, their children are watching them and taking example from them, and abandoning your wife for a younger one is treason to their divine contract, and a sign of weakness, a lack of vitality, and decay.

When she is old, she is a sage, the grandmother of his grandchildren, and she is his home. The house without her is just walls and dust. Memory. Loyalty. Love.

Love is the result of (a) marriage (based on reason), and should not be its cause!

Any society not holding this as an ideal is a sick and dying society. Like the one we live in today.
