ON THE CONSTITUTION

"No man can well doubt the propriety of placing a president of the United States under the most solemn obligations to preserve, protect, and defend the constitution. It is a suitable pledge of his fidelity and responsibility to his country; and creates upon his conscience a deep sense of duty, by an appeal, at once in the presence of God and man, to the most sacred and solemn sanctions, which can operate upon the human mind."

--Joseph Story, Commentaries on the Constitution, 1833. Joseph Story was an American lawyer and jurist who served on the Supreme Court of the United States from 1811 to 1845.

"On the other hand, the duty imposed upon him to take care, that the laws be faithfully executed, follows out the strong injunctions of his oath of office, that he will 'preserve, protect, and defend the constitution.' The great object of the executive department is to accomplish this purpose; and without it, be the form of government whatever it may, it will be utterly worthless for offence, or defence; for the redress of grievances, or the protection of rights; for the happiness, or good order, or safety of the people."
