Again, there is another student. He is trying to become a good playwright, or orator, or actor. He sees the same advertisement. He goes to the play and enjoys it very much. Every play he attends adds to his experience and increases his knowledge. The same action has become a virtue, for by going to the theater and giving his thought to the plays he has helped to accomplish his ideal. Therefore it all depends on our ideal whether the same action be a sin or a virtue. We have to follow and prove ourselves worthy of that ideal, and the further we go the more our ideal develops. However small it was at the beginning, we are always progressing as long as we follow it and wish to prove ourselves worthy of it; but when we stray from our ideal we lose the track. And if there is anything wrong or evil in the world, it is this: leaving the track of the ideal that we have set before ourselves.
