Far more excellent, in my opinion, than the seeds of wheat and barley that are sown at appropriate seasons, is man that is sown, for whom all things grow; and those seeds temperate husbandmen ever sow. Every foul and polluting practice must therefore be purged away from marriage; that the intercourse of the irrational animals may not be cast in our teeth, as more accordant with nature than human conjunction in procreation. Some of these, it must be granted, desist at the time in which they are directed, leaving creation to the working of Providence.
