"Here, then, is the great beauty of American government. The simple machinery of representation carried through all its parts gives facility for its being moulded at will to fit with the knowledge of the age. If imperfect in any or all of its parts, it bears within it a perfect principle — the principle of improvement. And, let us observe, that this principle is all that we can ever know of perfection. Knowledge, and all the blessings which spring out of knowledge, can never be more than progressive; and whatsoever sets open the door does all for us — does every thing."

“Another revolution! Naples free and all of Italy in insurrection! How wonderful has been the march of the human mind in these last thirty years … so may it be till the last link of the chains of slavery is broken and the banner of freedom waves over the whole earth!”

“If such a patriotism as we have last considered should seem likely to obtain in any country, it should be certainly in this. In this, which is truly the home of all nations, and in the veins of whose citizens flows the blood of every people on the globe. Patriotism, in the exclusive meaning, is surely not made for America. Mischievous every where, it were here both mischievous and absurd. The very origin of the people is opposed to it. The institutions, in their principle, militate against it. The day we are celebrating protests against it. It is for Americans, more especially to nourish a nobler sentiment; one more consistent with their origin, and more conducive to their future improvement. It is for them more especially to know why they love their country, not because it is their country, but because it is the palladium of human liberty — the favoured scene of human improvement. It is for them more especially, to know why they honour their institutions, and feel that they honour them because they are based on just principles. It is for them, more especially, to examine their institutions, because they have the means of improving them; to examine their laws, because at will they can alter them.”

“It has already been observed that women, wherever placed, however high or low in the scale of cultivation, hold the destinies of human kind. Men will ever rise or fall to the level of the other sex.”

“The great national and political revolution of '76 set the seal to the liberties of North America. And but for one evil, and that of immense magnitude, which the constitutional provision we have been considering does not fairly reach — I allude to negro slavery and the degradation of our coloured citizens — we could foresee for the whole of this magnificent country a certain future of uniform and peaceful improvement.”

“Opinions are not to be learned by rote, like the letters of an alphabet, or the words of a dictionary. They are conclusions to be formed, and formed by each individual in the sacred and free citadel of the mind, and there enshrined beyond the arm of law to reach, or force to shake; ay! and beyond the right of impertinent curiosity to violate, or presumptuous arrogance to threaten.”
