It cannot be said too often that actions are good or bad in the light of consequences, and that a clear perception of consequences would control actions.

Crimes were committed to punish crimes, and crimes were committed to prevent crimes. The world has been filled with prisons and dungeons, with chains and whips, with crosses and gibbets, with thumbscrews and racks, with hangmen and heads-men — and yet these frightful means and instrumentalities have committed far more crimes than they have prevented.... Ignorance, filth, and poverty are the missionaries of crime. As long as dishonorable success outranks honest effort — as long as society bows and cringes before the great thieves, there will be little ones enough to fill the jails.

All of the Ten Commandments that are good were old; all that were new art foolish. If Jehovah had been civilized he would have left out the commandment about keeping the Sabbath, and in its place would have said: "Thou shalt not enslave thy fellow-men."
