“In the study of history, slowness is an advantage. The scholar decelerates the fast-moving events of past days until his mind can fathom them. Then… he can demonstrate to the rashest king how he should have acted in battle.”

Context: It is a very poor thing, whether for nations or individuals, to advance the history of great deeds done in the past as an excuse for doing poorly in the present; but it is an excellent thing to study the history of the great deeds of the past, and of the great men who did them, with an earnest desire to profit thereby so as to render better service in the present. In their essentials, the men of the present day are much like the men of the past, and the live issues of the present can be faced to better advantage by men who have in good faith studied how the leaders of the nation faced the dead issues of the past. Such a study of Lincoln's life will enable us to avoid the twin gulfs of immorality and inefficiency—the gulfs which always lie one on each side of the careers alike of man and of nation. It helps nothing to have avoided one if shipwreck is encountered in the other. The fanatic, the well-meaning moralist of unbalanced mind, the parlor critic who condemns others but has no power himself to do good and but little power to do ill—all these were as alien to Lincoln as the vicious and unpatriotic themselves. His life teaches our people that they must act with wisdom, because otherwise adherence to right will be mere sound and fury without substance; and that they must also act high-mindedly, or else what seems to be wisdom will in the end turn out to be the most destructive kind of folly.

The Advancement of Learning (1605)
Context: The use of this feigned history hath been to give some shadow of satisfaction to the mind of man in those points wherein the nature of things doth deny it, the world being in proportion inferior to the soul; by reason whereof there is, agreeable to the spirit of man, a more ample greatness, a more exact goodness, and a more absolute variety, than can be found in the nature of things. Therefore, because the acts or events of true history have not that magnitude which satisfieth the mind of man, poesy feigneth acts and events greater and more heroical: because true history propoundeth the successes and issues of actions not so agreeable to the merits of virtue and vice, therefore poesy feigns them more just in retribution, and more according to revealed providence: because true history representeth actions and events more ordinary, and less interchanged, therefore poesy endueth them with more rareness, and more unexpected and alternative variations: so as it appeareth that poesy serveth and conferreth to magnanimity, morality, and to delectation. And therefore it was ever thought to have some participation of divineness, because it doth raise and erect the mind, by submitting the shows of things to the desires of the mind; whereas reason doth buckle and bow the mind into the nature of things.
