“Happiness depends more upon the internal frame of a person’s own mind, than on the externals in the world.”

“Nothing can illustrate these observations more forcibly, than a recollection of the happy conjuncture of times and circumstances, under which our Republic assumed its rank among the Nations; The foundation of our Empire was not laid in the gloomy age of Ignorance and Superstition, but at an Epoch when the rights of mankind were better understood and more clearly defined, than at any former period, the researches of the human mind, after social happiness, have been carried to a great extent, the Treasures of knowledge, acquired by the labours of Philosophers, Sages and Legislatures, through a long succession of years, are laid open for our use, and their collected wisdom may be happily applied in the Establishment of our forms of Government; the free cultivation of Letters, the unbounded extension of Commerce, the progressive refinement of Manners, the growing liberality of sentiment... have had a meliorating influence on mankind and increased the blessings of Society. At this auspicious period, the United States came into existence as a Nation, and if their Citizens should not be completely free and happy, the fault will be entirely their own.[Circular to the States, 8 June 1783 - Writings 26:484--89]”

“The alternate domination of one faction over another, sharpened by the spirit of revenge, natural to party dissension, which in different ages and countries has perpetrated the most horrid enormities, is itself a frightful despotism. But this leads at length to a more formal and permanent despotism. The disorders and miseries, which result, gradually incline the minds of men to seek security and repose in the absolute power of an individual; and sooner or later the chief of some prevailing faction, more able or more fortunate than his competitors, turns this disposition to the purposes of his own elevation, on the ruins of Public Liberty.”

“Our cruel and unrelenting Enemy leaves us no choice but a brave resistance, or the most abject submission; this is all we can expect - We have therefore to resolve to conquer or die: Our own Country's Honor, all call upon us for a vigorous and manly exertion, and if we now shamefully fail, we shall become infamous to the whole world. Let us therefore rely upon the goodness of the Cause, and the aid of the supreme Being, in whose hands Victory is, to animate and encourage us to great and noble Actions - The Eyes of all our Countrymen are now upon us, and we shall have their blessings, and praises, if happily we are the instruments of saving them from the Tyranny meditated against them. Let us therefore animate and encourage each other, and shew the whole world, that a Freeman contending for Liberty on his own ground is superior to any slavish mercenary on earth.”

“In politics as in philosophy, my tenets are few and simple. The leading one of which, and indeed that which embraces most others, is to be honest and just ourselves and to exact it from others, meddling as little as possible in their affairs where our own are not involved. If this maxim was generally adopted, wars would cease and our swords would soon be converted into reap hooks and our harvests be more peaceful, abundant, and happy.”

“There is nothing which can better deserve our patronage than the promotion of science and literature. Knowledge is in every country the surest basis of public happiness.”

“Associate yourself with men of good quality, if you esteem your own reputation; for ‘tis better to be alone than in bad company.”
