“No man is infinitely strong; for every creature that runs, flies, hops or crawls there is a terminal nemesis which he will not circumvent, which will finally do him in.”

Referring to the lack of established culture and the established institution of slavery in the United States, in "Review of Seybert’s Annals of the United States", published in The Edinburgh Review (1820)
Context: In the four quarters of the globe, who reads an American book? Or goes to an American play? or looks at an American picture or statue? What does the world yet owe to American physicians or surgeons? What new substances have their chemists discovered? Or what old ones have they advanced? What new constellations have been discovered by the telescopes of Americans? Who drinks out of American glasses? Or eats from American plates? Or wears American coats or gowns? or sleeps in American blankets? Finally, under which of the old tyrannical governments of Europe is every sixth man a slave, whom his fellow-creatures may buy and sell and torture?

Systematic Theology (1951–63)
Context: Man is infinitely concerned about the infinity to which he belongs, from which he is separated, and for which he is longing. Man is totally concerned about the totality which is his true being and which is disrupted in time and space. Man is unconditionally concerned about that which conditions his being beyond all the conditions in him and around him. Man is ultimately concerned about that which determines his ultimate destiny beyond all preliminary necessities and accidents.

1910s, The New Nationalism (1910)
Context: The right to regulate the use of wealth in the public interest is universally admitted. Let us admit also the right to regulate the terms and conditions of labor, which is the chief element of wealth, directly in the interest of the common good. The fundamental thing to do for every man is to give him a chance to reach a place in which he will make the greatest possible contribution to the public welfare. Understand what I say there. Give him a chance, not push him up if he will not be pushed. Help any man who stumbles; if he lies down, it is a poor job to try to carry him; but if he is a worthy man, try your best to see that he gets a chance to show the worth that is in him.
