7 And not only this sin has these effects, but every misplaced affection as well. For let us transfer, if you please, the argument from the unchaste woman unto money, and we shall see here also thick and unbroken darkness. For in the former case, inasmuch as the beloved object is one and shut up in one place, the feeling is not so violent; but in the case of money which shows itself every where, in silversmiths' shops, in taverns, in foundries for gold, in the houses of the wealthy, the passion blows a vehement gale.
For when servants swaggering in the market place, horses with golden trappings, men decked with costly garments, are seen with desire by him who has that distemper, the darkness becomes intense which envelopes him. And why speak of houses and silversmiths' shops? For my part I think that such persons, though it be but in a picture and image that they see the wealth, are convulsed, and grow wild, and rave. So that from all quarters the darkness gathers around them. And if they chance to behold a portraiture of a King, they admire not the beauty of the precious stones, nor yet the gold, nor the purple robe, but they pine away.
And as the wretched lover before mentioned, though he see but the image of the woman beloved, cleaves unto the lifeless thing; so this man also, beholding a lifeless image of wealth, is more strongly affected in the same way, as being holden of a more tyrannical passion. And he must henceforth either abide at home, or if he venture into the Forum, return home with innumerable hurts. For many are the objects which grieve his eyes. And just as the former sees nothing else save the woman, even so the latter hastens by poor persons, and all things else, that he may not obtain so much as a slight alleviation.
But upon the wealthy he steadily fixes his eyes; by the sight of them introducing the fire into his own soul mightily and vehemently. For it is a fire that miserably devours the person that falls into it; and if no hell were threatened nor yet punishment, this condition were itself punishment; to be continually tormented and never able to find an end to the malady.
