“lest the habit of work should be broken, and a taste for idleness acquired”

“the only way in which a human being can make some approach to knowing the whole of a subject, is by hearing what can be said about it by persons of every variety of opinion, and studying all modes in which it can be looked at by every character of mind. No wise man ever acquired his wisdom in any mode but this; nor is it in the nature of human intellect to become wise in any other manner.”

“There is always need of persons not only to discover new truths, and point out when what were once truths are true no longer, but also to commence new practices, and set the example of more enlightened conduct, and better taste and sense in human life.”

“Bad men need nothing more to compass their ends, than that good men should look on and do nothing.”

“Every man who says frankly and fully what he thinks is so far doing a public service. We should be grateful to him for attacking most unsparingly our most cherished opinions.”

“To prevent the weaker members of the community from being preyed upon by innumerable vultures, it was needful that there should be an animal of prey stronger than the rest, commissioned to keep them down. But as the king of vultures would be no less bent upon preying upon the flock than any of the minor harpies, it was indispensable to be in a perpetual attitude of defense against his beak and claws.”

“[People] ask themselves, what is suitable for my position? What is usually done by persons of my station and percuniary circumstances? Or (worse still) what is usually done by persons of a station and circumstances superior to mine? I do not mean that they choose what is customary in preference to what suits their own inclinations. It does not occur to them to have any inclination, except for what is customary. Thus the mind itself is bowed to the yoke: even in what people do for pleasure, conformity is the first thing thought of; they like in crowds; they exercise choice only among things that are commonly done: peculiarity of taste, eccentricity of conduct, are shunned equally with crimes: until by dint of not following their own nature they have no nature to follow: their human capacities are withered and starved: they become incapable of any strong wishes or native pleasures, and are generally without either opinions or feelings of home growth, or properly their own.”
