“My excuse for not lecturing against the use of tobacco is, that I never chewed it; that is a penalty which reformed tobacco chewers have to pay; though there are things enough I have chewed, which I could lecture against. If you should ever be betrayed into any of these philanthropies, do not let your left hand know what your right hand does , for it is not worth knowing. Rescue the drowning and tie your shoe-strings. Take your time, and set about some free labor.”

“The only obligation which I have a right to assume is to do at any time what I think right.”

“The true and not despairing Friend will address his Friend in some such terms as these."I never asked thy leave to let me love thee,--I have a right. I love thee not as something private and personal, which is your own, but as something universal and worthy of love, which I have found. O, how I think of you! You are purely good, --you are infinitely good. I can trust you forever. I did not think that humanity was so rich. Give me an opportunity to live.”

“If the injustice is part of the necessary friction of the machine of government, let it go, let it go: perchance it will wear smooth--certainly the machine will wear out… but if it is of such a nature that it requires you to be the agent of injustice to another, then I say, break the law. Let your life be a counter-friction to stop the machine. What I have to do is to see, at any rate, that I do not lend myself to the wrong which I condemn.”

“Some of you, we all know, are poor, find it hard to live, are sometimes, as it were, gasping for breath. I have no doubt that some of you who read this book are unable to pay for all the dinners which you have actually eaten, or for the coats and shoes which are fast wearing or are already worn out, and have come to this page to spend borrowed or stolen time, robbing your creditors of an hour. It is very evident what mean and sneaking lives many of you live, for my sight has been whetted by experience; always on the limits, trying to get into business and trying to get out of debt, a very ancient slough, called by the Latins aes alienum, another's brass, for some of their coins were made of brass; still living, and dying, and buried by this other's brass; always promising to pay, promising to pay, tomorrow, and dying today, insolvent; seeking to curry favor, to get custom, by how many modes, only not state-prison offences; lying, flattering, voting, contracting yourselves into a nutshell of civility or dilating into an atmosphere of thin and vaporous generosity, that you may persuade your neighbor to let you make his shoes, or his hat, or his coat, or his carriage, or import his groceries for him; making yourselves sick, that you may lay up something against a sick day, something to be tucked away in an old chest, or in a stocking behind the plastering, or, more safely, in the brick bank; no matter where, no matter how much or how little.”

“Perhaps this was the first instance of that quiet way of "speaking for" a place not yet occupied, or at least not improved as much as it may be, which their descendants have practised, and are still practising so extensively. Not Any seems to have been the sole proprietor of all America before the Yankees [...] At any rate, I know that if you hold a thing unjustly, there will surely be the devil to pay at last.”

“A man receives only what he is ready to receive, whether physically or intellectually or morally, as animals conceive at certain seasons their kind only. We hear and apprehend only what we already half know. If there is something which does not concern me, which is out of my line, which by experience or by genius my attention is not drawn to, however novel and remarkable it may be, if it is spoken, we hear it not, if it is written, we read it not, or if we read it, it does not detain us. Every man thus tracks himself through life, in all his hearing and reading and observation and traveling. His observations make a chain. The phenomenon or fact that cannot in any wise be linked with the rest which he has observed, he does not observe. By and by we may be ready to receive what we cannot receive now. I find, for example, in Aristotle some thing about the spawning, etc., of the pout and perch, because I know something about it already and have my attention aroused; but I do not discover till very late that he has made other equally important observations on the spawning of other fishes, because I am not interested in those fishes.”
