(47) Such a man as this the lawgiver calls labour, who, not perceiving the true laws of nature, falsely assents to those which are in force among men, saying, “It is not the custom in our country to give the younger daughter in marriage before the Elder.”{11}{#ge 29:26.} (48) For he thinks that it behoves him to adhere to the classification arising from the consideration of time, according to which, that which is oldest is entitled to priority, and after that, that which is the younger is admitted to a participation in their joint rights. But the practiser in wisdom, knowing that natures are not subject to time, desires what is younger first, and what is older afterwards. And moral reason agrees with him in this matter, for it is necessary for those who practise anything, first of all to come to the more recent learning, in order that after that, they may be able to derive advantage from that which is more perfect. (49) And, on this account, the lovers of virtue and excellence do not approach the doors of the older philosophy before they have become familiar with these younger parts of it, grammar, and geometry, and the whole range of encyclical learning; for these subordinate branches do always attend upon those, who with sincerity and purity of purpose court wisdom.
