Every Sunday, devout members of the congregation in church--models of excellence in their own estimation, and in the estimation of their neighbours--declare that they have done those things which they ought not to have done, and that there is no health in them.

Will you believe that they are encouraged by their Prayer-books to present this sad exposure of the frailty of their own admirable characters?
How inconsistent--and yet how entirely true! Lord Harry, as you rightly say, behaved nobly in trying to save my dear lost brother.

He ought, as you think, and as other people think, to be consistently noble, after that, in all his thoughts and actions, to the end of his life.

Suppose that temptation does try him--such temptation, Iris, as you innocently present--why doesn't he offer a superhuman resistance?
You might as well ask, Why is he a mortal man?
How inconsistent, how improbable, that he should have tendencies to evil in him, as well as tendencies to good! Ah, I see you don't like this.

It would be infinitely more agreeable (wouldn't it ?) if Lord Harry was one of the entirely consistent characters which are sometimes presented in works of fiction.
