"Education, then, beyond all other devices of human origin, is the great equalizer of the conditions of men, — the balance-wheel of the social machinery. I do not here mean that it so elevates the moral nature as to make men disdain and abhor the oppression of their fellow-men. This idea pertains to another of its attributes. But I mean that it gives each man the independence and the means by which he can resist the selfishness of other men. It does better than to disarm the poor of their hostility towards the rich: it prevents being poor."

"Manners easily and rapidly mature into morals. As childhood advances to manhood, the transition from bad manners to bad morals is almost imperceptible. Vulgar and obscene forms of speech keep vulgar and obscene objects before the mind, engender impure images in the imagination, and make unlawful desires prurient. From the prevalent state of the mind, actions proceed, as water rises from a fountain."

"Lost — Yesterday, somewhere between sunrise and sunset, two golden hours, each set with sixty diamond minutes. No reward is offered, for they are gone forever."

"If any man seeks for greatness, let him forget greatness and ask for truth, and he will find both."

"Resolve to edge in a little reading every day, if it is but a single sentence. If you gain fifteen minutes a day, it will make itself felt at the end of the year."

"Every school boy and school girl who has arrived at the age of reflection ought to know something about the history of the art of printing, papermaking, and so forth. … All children will work better if pleased with their tools; and there are no tools more ingeniously wrought, or more potent than those which belong to the art of the printer. Dynasties and governments used to be attacked and defended by arms; now the attack and the defence are mainly carried on by types. To sustain any scheme of state policy, to uphold one administration or to demolish another, types, not soldiers, are brought into line. Hostile parties, and sometimes hostile nations, instead of fitting out martial or naval expeditions, establish printing presses, and discharge pamphlets or octavoes at each other, instead of cannon balls. The poniard and the stiletto were once the resource of a murderous spirit; now the vengeance, which formerly would assassinate in the dark, libels character, in the light of day, through the medium of the press. But through this instrumentality good can be wrought as well as evil. Knowledge can be acquired, diffused, perpetuated. An invisible, inaudible, intangible thought in the silent chambers of the mind, breaks away from its confinement, becomes imbodied in a sign, is multiplied by myriads, traverses the earth, and goes resounding down to the latest posterity."

"God draweth straight lines but we call them crooked."

"Forts, arsenals, garrisons, armies, navies, are means of security and defence, which were invented in half-civilized times and in feudal or despotic countries; but schoolhouses are the republican line of fortifications, and if they are dismantled and dilapidated, ignorance and vice will pour in their legions through every breach."

"Anyone who has read anything of Horace Mann knows that he is a sort of patron saint of progressive education not only because of his ideas (very advanced for his day) about the way children should be treated, not only because he advocated a personal and humane atmosphere in the school in the relation of children and teachers, but because, above all, he was the prophet of the idea of the absolute necessity of free public education for the existence and preservation of a democratic way of life; or, as he said in the phraseology of his time, "republican institutions of self-government.""

"The 1830s, in fact, gave rise to an educational awakening, led by such reformers as Horace Mann, James G. Carter, Henry Barnard, and William Russell, all of whom used Massachusetts and other New England states as their laboratory. Their crusading helped to generate public support for common schools. Mann, acknowledged as the father of the common school movement, argued that these institutions should be publicly controlled, publicly supported, and open to all."

"Control of children and their education is control of the future. Humanists have always understood this. Horace Mann, James G. Carter, and their many associates (including Senator Charles G. Sumner) were all Unitarians; they hated the Puritan faith of their forefathers with a passion. Their purpose in promoting state control of education was twofold. First, they rightfully understood that the only way to destroy Biblical faith was to control the schools and, little by little, remove Christianity and introduce Humanism. Second, they were Centralists or statist, men who believed that salvation comes by work of statist legislation or law."

"I would ask, if this modesty is not attractive also, when manifested in the other sex? It was strikingly marked in Horace Mann, when presiding over the late National Educational Convention in this city. The retiring modesty of William Ellery Channing was beautiful, as well as of many others who have filled elevated stations in society. These virtues, differing as they may in degree in man and woman, are of the same nature, and call forth our admiration wherever manifested."

"The process did not begin with Horace Mann, although he probably did more to humanize American education in the nineteenth century than any other educator, and thus we tend to trace humanistic roots back to him. Mann was vigorously opposed by ministers of his day, who foresaw the shift from a biblical to a humanistic base for education, but their resistance was gradually overcome."

"He is a delightful companion and friend, and among all the excellent men whom we met in Boston, none entwined themselves more deeply and closely with our affections than Horace Mann."

"Let us not be content to wait and see what will happen, but give us the determination to make the right things happen."

"Character is what God and the angels know of us; reputation is what men and women think of us."

"If an idiot were to tell you the same story every day for a year, you would end by believing it."

"Do not think of knocking out another person's brains because he differs in opinion from you. It would be as rational to knock yourself on the head because you differ from yourself ten years ago."

"Much that we call evil is really good in disguises; and we should not quarrel rashly with adversities not yet understood, nor overlook the mercies often bound up in them."

"Evil and good are God's right hand and left."

"Let us labor for that larger and larger comprehension of truth, that more and more thorough repudiation of error, which shall make the history of mankind a series of ascending developments."

"Knowledge is a mimic creation."
