Letters 87.29

The second meaning is as follows: that through which we become involved in evils is not a good. And it will not logically follow from our proposition that we become involved in evils through riches or through pleasure; otherwise, if it is through riches that we become involved in many evils, riches are not only not a good, but they are positively an evil. You, however, maintain merely that they are not a good. Moreover,” the objector says, “you grant that riches are of some use. You reckon them among the advantages; and yet on this basis they cannot even be an advantage, for it is through the pursuit of riches that we suffer much disadvantage.”
