The leading rule for the lawyer, as for the man of every calling, is diligence.
We humans do, when the cause is sufficient, spend our lives. We throw ourselves onto the grenade to save our buddies in the foxhole. We rise out of the trenches and charge the entreched enemy and die like maggots under a blowtorch. We strap bombs on our bodies and blow ourselves up in the midst of our enemies. We are, when the cause is sufficient, insane.
