The Study of History (1895)
Context: Most of this, I suppose, is undisputed, and calls for no enlargement. But the weight of opinion is against me when I exhort you never to debase the moral currency or to lower the standard of rectitude, but to try others by the final maxim that governs your own lives, and to suffer no man and no cause to escape the undying penalty which history has the power to inflict on wrong. The plea in extenuation of guilt and mitigation of punishment is perpetual. At every step we are met by arguments which go to excuse, to palliate, to confound right and wrong, and reduce the just man to the level of the reprobate. The men who plot to baffle and resist us are, first of all, those who made history what it has become. They set up the principle that only a foolish Conservative judges the present time with the ideas of the past; that only a foolish Liberal judges the past with the ideas of the present.

Veto Message Regarding the Bank of the United States http://avalon.law.yale.edu/19th_century/ajveto01.asp (10 July 1832)
Often paraphrased as: If Congress has the right under the constitution to issue paper money, it was given them to be used by themselves, not to be delegated to individuals or corporations.
1830s
Context: It is maintained by some that the bank is a means of executing the constitutional power “to coin money and regulate the value thereof.” Congress have established a mint to coin money and passed laws to regulate the value thereof. The money so coined, with its value so regulated, and such foreign coins as Congress may adopt are the only currency known to the Constitution. But if they have other power to regulate the currency, it was conferred to be exercised by themselves, and not to be transferred to a corporation. If the bank be established for that purpose, with a charter unalterable without its consent, Congress have parted with their power for a term of years, during which the Constitution is a dead letter. It is neither necessary nor proper to transfer its legislative power to such a bank, and therefore unconstitutional.
