"I think that I have, as yet, done nothing which deserves gratitude. Especially may we ask, Ought we to lay claim to any thanks, inasmuch as what we do in behalf of others, we do, first of all, to secure our own self-approval."

"Good, good. Wise already. Yet one thing more. Do you believe in natural depravity, and if you do, since when?"

Perhaps the belief in depravity is also merely passion."

The doctor nodded several times, and then said,—

"Only one question more. Are you sensitive—vulnerable?"

"I might perhaps urge your friendly testing as a proof that I am not."
