“All men will come to me in due time, but theirs is the agony of awaiting.”

Letter to Fanny McCullough (23 December 1862); Collected Works of Abraham Lincoln, edited by Roy P. Basler
1860s
Context: In this sad world of ours, sorrow comes to all; and, to the young, it comes with bitterest agony, because it takes them unawares. The older have learned to ever expect it. I am anxious to afford some alleviation of your present distress. Perfect relief is not possible, except with time. You can not now realize that you will ever feel better. Is not this so? And yet it is a mistake. You are sure to be happy again. To know this, which is certainly true, will make you some less miserable now. I have had experience enough to know what I say; and you need only to believe it, to feel better at once.

Epigraph, based upon the style of Samuel Johnson in The History of Rasselas, Prince of Abissinia (1759), using a fictional reference to Imlac the philosopher in Johnson's tale.

Context: Even when pressed by the demands of inner truth, men do not easily assume the task of opposing their government's policy, especially in time of war. Nor does the human spirit move without great difficulty against all the apathy of conformist thought within one's own bosom and in the surrounding world. Moreover, when the issues at hand seem as perplexing as they often do in the case of this dreadful conflict, we are always on the verge of being mesmerized by uncertainty; but we must move on.
And some of us who have already begun to break the silence of the night have found that the calling to speak is often a vocation of agony, but we must speak. We must speak with all the humility that is appropriate to our limited vision, but we must speak.

We must speak with all the humility that is appropriate to our limited vision, but we must speak. And we must rejoice as well, for in all our history there has never been such a monumental dissent during a war, by the American people.
