“Think calmly and well, upon this whole subject. If there be an object to hurry any of you, in hot haste, to a step you would never take deliberately, that object will be frustrated by taking time; but no good object can be frustrated by it.”
– Abraham Lincoln, from his first inaugural address, March 4, 1861, (our italics)
“This whole subject” that Lincoln refers to is the Civil War, which would begin the following month at Fort Sumter. That quote should’ve made the book.
