”It would reduce the whole instrument to a single phrase, that of instituting a Congress with power to do whatever would be for the good of the United States; and as they would be the sole judges of the good or evil, it would be also a power to do whatever evil they please. Certainly no such universal power was meant to be given them. It [the Constitution] was intended to lace them up straightly within the enumerated powers and those without which, as means, these powers could not be carried into effect.” –Thomas Jefferson, Opinion on a National Bank, 1791
