Now we come to what people call sin and virtue. In all ages they have pointed out, "This particular thing is sin, that particular thing is virtue." Whenever the wise have done it they have done it rightly, and yet they differ from one another. If a greater light is thrown upon this subject it is possible to view sin in the light of sin and also to view sin in the light of virtue. Very often one can also see that under the cover of virtue there was a sin, and under the cover of sin there was a virtue.
