It is useless to list the damage that can be caused and effected by too strict a repression of sexual love in the case of those who are troubled with a superabundance of sexual drive. In their case this may be the cause of certain bodily ailments and mental problems, not to speak of the unrecognised evils which may not even be named. It is quite different in the case of those whose sexual love is so weak that they can resist the strains of its lust; and equally so with those who are free while still youthful to enter into legitimate cohabitation without the waste of worldly wealth, so at the first outset. Since this is what happens in heaven when children have reached marriageable age, no one there knows what fornication is. But things are different on earth, where marriages cannot take place except once the period of youth is over, as often happens in kingdoms where there is a long period of obligatory duties, and the means of keeping a house and family have to be earned; only then is it possible to court a worthy bride.
