“Whenever, if ever, he and we can come together on principle so that our cause may have assistance from his great ability, I hope to have interposed no adventitious obstacle. But clearly, he is not now with us — he does not pretend to be — he does not promise ever to be. Our cause, then, must be intrusted to, and conducted by, its own undoubted friends — those whose hands are free, whose hearts are in the work — who do care for the result.”

Context: Every event has had its cause, and nothing, not the least wind that blows, is accident or causeless. To understand what happens now one must find the cause, which may be very long ago in its beginning, but is surely there, and therefore a knowledge of history as detailed as possible is essential if we are to comprehend the present and be prepared for the future. Fate, Mr. Kung taught me, is not the blind superstition or helplessness that waits stupidly for what may happen. Fate is unalterable only in the sense that given a cause, a certain result must follow, but no cause is inevitable in itself, and man can shape his world if he does not resign himself to ignorance.

The Crisis No. I.
1770s, The American Crisis (1776–1783)
Context: It matters not where you live, or what rank of life you hold, the evil or the blessing will reach you all. The far and the near, the home counties and the back, the rich and the poor, will suffer or rejoice alike. The heart that feels not now is dead; the blood of his children will curse his cowardice, who shrinks back at a time when a little might have saved the whole, and made them happy. I love the man that can smile in trouble, that can gather strength from distress, and grow brave by reflection. 'Tis the business of little minds to shrink; but he whose heart is firm, and whose conscience approves his conduct, will pursue his principles unto death.
My own line of reasoning is to myself as straight and clear as a ray of light. Not all the treasures of the world, so far as I believe, could have induced me to support an offensive war, for I think it murder; but if a thief breaks into my house, burns and destroys my property, and kills or threatens to kill me, or those that are in it, and to "bind me in all cases whatsoever" to his absolute will, am I to suffer it? What signifies it to me, whether he who does it is a king or a common man; my countryman or not my countryman; whether it be done by an individual villain, or an army of them? If we reason to the root of things we shall find no difference; neither can any just cause be assigned why we should punish in the one case and pardon in the other. Let them call me rebel and welcome, I feel no concern from it; but I should suffer the misery of devils, were I to make a whore of my soul by swearing allegiance to one whose character is that of a sottish, stupid, stubborn, worthless, brutish man.
