Measure what is measurable, and make measurable what is not so.
The purpose of marriage is not to have pleasure and to be idle, but to procreate and bring up children, to support a household. This, of course, is a huge burden full of great cares and toils. But you have been created by God to be a husband or a wife that you may learn to bear these troubles. Those who have no love for children are... unworthy of being called men or women; for they despise the blessing of God, the creator and author of marriage.
