House of Representatives, June 16, 1789:

...If their ideas should succeed, a principle of mortality will be infused into a government which the lovers of mankind have wished might last to the end of the world. With a mixture of the executive and legislative powers in one body, no government can long remain uncorrupt. With a corrupt executive, liberty may long retain a trembling existence. With a corrupt legislature, it is impossible: the vitals of the Constitution would be mortified, and death must follow in every step. A government thus formed would be the most formidable curse that could befall this country. Perhaps an enlightened people might timely foresee and correct the error; but if a season was allowed for such a compound to grow and produce its natural fruit, it would either banish liberty, or the people would he driven to exercise their unalienable right, the right of uncivilized nature, and destroy a monster whose voracious and capacious jaws could crush and swallow up themselves and their posterity....
