Book 4.3
It was necessary to insert this argument, my Liberalis, because it is the part of virtue to bestow those benefits which we are now discussing, and it is most disgraceful to bestow benefits for any other purpose than that they should be free gifts. If we give with the hope of receiving a return, we should give to the richest men, not to the most deserving: whereas we prefer a virtuous poor man to an unmannerly rich one. That is not a benefit, which takes into consideration the fortune of the receiver. Moreover, if our only motive for benefiting others was our own advantage, those who could most easily distribute benefits, such as rich and powerful men, or kings, and persons who do not stand in need of the help of others, ought never to do so at all; the gods would not bestow upon us the countless blessings which they pour upon us unceasingly by night and by day, for their own nature suffices them in all respects, and renders them complete, safe, and beyond the reach of harm; they will, therefore, never bestow a benefit upon any one, if self and self interest be the only cause for the bestowal of benefits. To take thought, not where your benefit will be best bestowed, but where it may be most profitably placed at interest, from whence you will most easily get it back, is not bestowal of benefits, but usury. Now the gods have nothing to do with usury; it follows, therefore, that they cannot be liberal; for if the only reason for giving is the advantage of the giver, since God cannot hope to receive any advantages from us, there is no cause why God should give anything.
