This is a clip from his inaugural address.

Unpleasant and even dangerous as collisions may sometimes be between the constituted authorities of the citizens of our country in relation to the lines which separate their respective jurisdictions, the results can be of no vital injury to our institutions if that ardent patriotism, that devoted attachment to liberty, that spirit of moderation and forbearance for which our countrymen were once distinguished, continue to be cherished. If this continues to be the ruling passion of our souls, the weaker feeling of the mistaken enthusiast will be corrected, the Utopian dreams of the scheming politician dissipated, and the complicated intrigues of the demagogue rendered harmless. The spirit of liberty is the sovereign balm for every injury which our institutions may receive. On the contrary, no care that can be used in the construction of our Government, no division of powers, no distribution of checks in its several departments, will prove effectual to keep us a free people if this spirit is suffered to decay; and decay it will without constant nurture. To the neglect of this duty the best historians agree in attributing the ruin of all the republics with whose existence and fall their writings have made us acquainted. The same causes will ever produce the same effects, and as long as the love of power is a dominant passion of the human bosom, and as long as the understandings of men can be warped and their affections changed by operations upon their passions and prejudices, so long will the liberties of a people depend on their own constant attention to its preservation. The danger to all well-established free governments arises from the unwillingness of the people to believe in its existence or from the influence of designing men diverting their attention from the quarter whence it approaches to a source from which it can never come. This is the old trick of those who would usurp the government of their country. In the name of democracy they speak, warning the people against the influence of wealth and the danger of aristocracy. History, ancient and modern, is full of such examples. Caesar became the master of the Roman people and the senate under the pretense of supporting the democratic claims of the former against the aristocracy of the latter; Cromwell, in the character of protector of the liberties of the people, became the dictator of England, and Bolivar possessed himself of unlimited power with the title of his country's liberator. There is, on the contrary, no instance on record of an extensive and well-established republic being changed into an aristocracy. The tendencies of all such governments in their decline is to monarchy, and the antagonist principle to liberty there is the spirit of faction  a spirit which assumes the character and in times of great excitement imposes itself upon the people as the genuine spirit of freedom, and, like the false Christs whose coming was foretold by the Savior, seeks to, and were it possible would, impose upon the true and most faithful disciples of liberty. It is in periods like this that it behooves the people to be most watchful of those to whom they have intrusted power. And although there is at times much difficulty in distinguishing the false from the true spirit, a calm and dispassionate investigation will detect the counterfeit, as well by the character of its operations as the results that are produced. The true spirit of liberty, although devoted, persevering, bold, and uncompromising in principle, that secured is mild and tolerant and scrupulous as to the means it employs, whilst the spirit of party, assuming to be that of liberty, is harsh, vindictive, and intolerant, and totally reckless as to the character of the allies which it brings to the aid of its cause. When the genuine spirit of liberty animates the body of a people to a thorough examination of their affairs, it leads to the excision of every excrescence which may have fastened itself upon any of the departments of the government, and restores the system to its pristine health and beauty. But the reign of an intolerant spirit of party amongst a free people seldom fails to result in a dangerous accession to the executive power introduced and established amidst unusual professions of devotion to democracy.
