Towards the preservation of your government, and the permanency of your present happy state, it is requisite, not only that you steadily discountenance irregular opposition to its acknowledged authority, but also that you resist with care the spirit of innovation upon its principles, however specious the pretext. One method of assault may be to effect, in the forms of the constitution, alterations which will impair the energy of the system, and thus to undermine what cannot be directly overthrown. In all the changes to which you may be invited, remember that time and habit are at least as necessary to fix the true character of government as of other human institutions; that experience is the surest standard by which to test the real tendency of the existing constitution of a country; that facility in changes, upon the credit of mere hypothesis and opinion, exposes to perpetual change, from the endless variety of hypothesis and opinion; and remember, especially, that, for the efficient management of your common interests, in a country so extensive as ours, a government of as much vigor as is consistent with the perfect security of liberty is indispensable. Liberty itself will find in such a government, with powers properly distributed and adjusted, its surest guardian. It is, indeed, little else than a name, where the government is too feeble to withstand the enterprise of faction, to confine each member of the society within the limits prescribed by the laws, and to maintain all in the secure and tranquil enjoyment of the rights of person and property.... Of all the dispositions and habits which lead to political prosperity, religion and morality are indispensable supports. In vain would that man claim the tribute of patriotism who should labor to subvert these great pillars of human happiness, these firmest props of the duties of men and citizens. The mere politician, equally with the pious man, ought to respect and to cherish them. A volume could not trace all their connections with private and public felicity. Let it simply be asked, where is the security for property, for reputation, for life, if the sense of religious obligation desert the oaths which are the instruments of investigation in courts of justice? And let us with caution indulge the supposition that morality can be maintained without religion. Whatever may be conceded to the influence of refined education on minds of peculiar structure, reason and experience both forbid us to expect that national morality can prevail in exclusion of religious principle.... Promote, then, as an object of primary importance, institutions for the general diffusion of knowledge. In proportion as the structure of a government gives force to public opinion it is essential that public opinion should be enlightened.
