De Viris Magnanimis Amore Præclarissimis
Know that in the Mind of Man is much Wisdom that is hidden, being the Treasure of his Sire that he inheriteth. Thus, nigh all of his moral Nature is unknown to him until his Puberty; that is, this Nature pertaineth not unto the Recording and Judging Apparatus of his Brain until it is put therein by the Stirring of that deeper Nature within him. Thou wilt mark also that great Men are commonly great Lovers; and this is in Part also because (consciously or not) they are ware of that Secret following, that every Act of Love communicateth somewhat of the Wisdom stored within him to his percipient Mind. Yet must such Act be done rightly, according to Art; and unless such Act is of Profit alike to Mind and Body, it is an Error. This then is true Doctrine; which if it be understanded aright of thee, shall make diamond-clear thy Path in Love, which (to them that know not this) is so obscure and perilous that I believe there is not one Man in Ten Thousand that cometh not to Misadventure therein.
