Letters 71.21

“What,” you say, “do you call reclining at a banquet and submitting to torture equally good?” Does this seem surprising to you? You may be still more surprised at the following,—that reclining at a banquet is an evil, while reclining on the rack is a good, if the former act is done in a shameful, and the latter in an honourable manner. It is not the material that makes these actions good or bad; it is the virtue. All acts in which virtue has disclosed itself are of the same measure and value.
