The principles which should govern the commercial intercourse of nations, do not differ from those which regulate the dealings of private individuals. - Robert Peel

The police are the public and the public are the police.

[Famine-stricken districts in Ireland] would require some better consolation than the doctrine of Adam Smith on the true Principles of demand and supply and the danger of Government interference.

I boldly maintain that the principle of protection to domestic industry, meaning thereby legislative encouragement for purpose of protection—duties on import imposed for that purpose, and not for revenue, is a vicious principle. I contest the hon. Gentleman's assumption, that you cannot fight hostile tariffs by free imports. I so totally dissent from that assumption, that I maintain that the best way to compete with hostile tariffs is to encourage free imports. So far from thinking the principle of protection a salutary principle, I maintain that the more widely you extend it, the greater the injury you will inflict on the national wealth, and the more you will cripple the national industry.
