For we all know that there is no converse worth the mention that does not comprise affection.

Besides, in the enjoyment of physical beauty there is a point of surfeit, so that one cannot help feeling toward his favourite the same effect that he gets toward food by gratification of the appetite.

Now, no further argument is necessary to show that a soul verdant with the beauty of freeborn men and with a disposition that is reverent and noble, a soul that from the very first displays its leadership among its own fellows and is kindly withal, feels an admiration and an affection for the object of its love; but I will go on to prove the reasonableness of the position that such a lover will have his affection returned.
