No moral system can rest solely on authority.

If you punish a child for being naughty, and reward him for being good, he will do right merely for the sake of the reward; and when he goes out into the world and finds that goodness is not always rewarded, nor wickedness always punished, he will grow into a man who only thinks about how he may get on in the world, and does right or wrong according as he finds either of advantage to himself.

Ignore death up to the last moment; then, when it can't be ignored any longer, have yourself squirted full of morphia and shuffle off in a coma. Thoroughly sensible, humane and scientific, eh?

We have convictions only if we have studied nothing thoroughly.

I think that if God forgives us we must forgive ourselves. Otherwise it is almost like setting up ourselves as a higher tribunal than Him.

There are two types of poor people, those who are poor together and those who are poor alone. The first are the true poor, the others are rich people out of luck.

Criticism alone can sever the root of materialism, fatalism, atheism, free-thinking, fanaticism, and superstition, which can be injurious universally; as well as of idealism and skepticism, which are dangerous chiefly to the Schools, and hardly allow of being handed on to the public.

An observer studying the Solar system dispassionately, and finding himself capable of bringing the four giant planets to his notice, could reasonably say that the Solar system consisted of one star, four planets, and some traces of debris.

There is no method of reasoning more common, and yet none more blameable, than, in philosophical disputes, to endeavour the refutation of any hypothesis, by a pretence of its dangerous consequences to religion and morality. When any opinion leads to absurdities, it is certainly false; but it is not certain that an opinion is false, because it is of dangerous consequence. Such topics, therefore, ought entirely to be forborne; as serving nothing to the discovery of truth, but only to make the person of an antagonist odious.

The consciousness of being betrayed is to the collective consciousness of a sacred group what a certain form of schizophrenia is to the individual...it is a form of madness.

For it is the chief characteristic of the religion of science, that it works, and that such curses as that of Aporat's are really deadly.

I think of the course of human history as a long, swelling, increasingly polyphonic poem - a poem that leads up to nothing save itself. When the species is extinct, "human nature's total message" will not be a set of propositions, but a set of vocabularies - the more, and the more various, the better.

As for the Soothsayer, although I am certain no one feels the true beauties of that work better than I, I am far from finding these beauties in the same places as the infatuated public does. They are not the products of study and knowledge, but rather are inspired by taste and sensitivity.

When the leaders choose to make themselves bidders at an auction of popularity, their talents, in the construction of the state, will be of no service. They will become flatterers instead of legislators; the instruments, not the guides, of the people.

By what aberration has suicide, the only truly normal action, become the attribute of the flawed?

And happiness is thought to depend on leisure; for we are busy that we may have leisure, and make war that we may live in peace.

What is new in our time is the increased power of the authorities to enforce their prejudices.

When one cultivates to the utmost the principles of his nature, and exercises them on the principle of reciprocity, he is not far from the path. What you do not like when done to yourself, do not do to others.

Because the peculiarity of man is that his machinery for reaction on external things has involved an imaginative transcript of these things, which is preserved and suspended in his fancy; and the interest and beauty of this inward landscape, rather than any fortunes that may await his body in the outer world, constitute his proper happiness. By their mind, its scope, quality, and temper, we estimate men, for by the mind only do we exist as men, and are more than so many storage-batteries for material energy. Let us therefore be frankly human. Let us be content to live in the mind.

When any work seems to have required immense force and labor to affect it, the idea is grand. Stonehenge, neither for disposition nor ornament, has anything admirable; but those huge rude masses of stone, set on end, and piled each on other, turn the mind on the immense force necessary for such a work. Nay, the rudeness of the work increases this cause of grandeur, as it excludes the idea of art and contrivance; for dexterity produces another sort of effect, which is different enough from this.

The wise soul feareth not death; rather she sometimes striveth for death, she goeth beyond to meet her. Yet eternity maintaineth her substance throughout time, immensity throughout space, universal form throughout motion.

We are all ready to be savage in some cause. The difference between a good man and a bad one is the choice of the cause.

Reason nevertheless prevails in world history.

"We may ignore, but we can nowhere evade, the presence of God. The world is crowded with Him. He walks everywhere incognito."

All happiness or unhappiness solely depends upon the quality of the object to which we are attached by love.

Be charitable before Wealth makes thee covetous.

Whenever a theory appears to you as the only possible one, take this as a sign that you have neither understood the theory nor the problem which it was intended to solve.

I think that there is nothing, not even crime, more opposed to poetry, to philosophy, ay, to life itself, than this incessant business.

I think I can hardly overrate the malignity of the principles of Protestant ascendancy, as they affect Ireland; or of Indianism, as they affect these countries, and as they affect Asia; or of Jacobinism, as they affect all Europe, and the state of human society itself. The last is the greatest evil.

Ideas are refined and multiplied in the commerce of minds. In their splendor, images effect a very simple communion of souls.

For this, to draw a right line from every point, to every point, follows the definition, which says, that a line is the flux of a point, and a right line an indeclinable and inflexible flow.

The world is chaos. Nothingness is the yet-to-be-born god of the world.

In the old system, the body of the condemned man became the king's property, on which the sovereign left his mark and brought down the effects of his power. Now he will be rather the property of society, the object of a collective and useful appropriation.

The weapon of the Republic is terror, and virtue is its strength.

A bad feeling is a commotion of the mind repugnant to reason, and against nature.

The good life, as I conceive it, is a happy life. I do not mean that if you are good you will be happy; I mean that if you are happy you will be good.

France wanted to make proselytes to her opinions, and turn every government in the world into a republic. If every government was against her, it was because she had declared herself hostile to every government. He knew of nothing to which this strange republic could be compared, but to the system of Mahomet, who with the koran in one hand, and a sword in the other, held out the former to the acceptance of mankind, and with the latter compelled them to adopt it as their creed. The koran which France held out, was the declaration of the rights of man and universal fraternity; and with the sword she was determined to propagate her doctrines, and conquer those whom she could not convince.

"For I am holy." When I hear these words I recognize the voice of the Saviour. But shall I take away my own? Certainly when He speaks thus He speaks in inseparable union with His body. But can I say, "I am holy"? If I mean a holiness that I have not received, I should be proud and a liar; but if I mean a holiness that I have received - as it is written: "Be ye holy because I the Lord your God am holy" (Lev. 19:2) - then let the body of Christ say these words. And let this one man, who cries from the ends of the earth, say with his Head and united with his Head: "I am holy." … That is not foolish pride, but an expression of gratitude. If you were to say that you are holy of yourselves, that would be pride; but if, as one of Christ's faithful and as a member of Christ, you say that you are not holy, you are ungrateful.

At the very beginning of my fevers and sicknesses that cast me down, whilst still entire, and but little, disordered in health, I reconcile myself to Almighty God by the last Christian, offices, and find myself by so doing less oppressed and more easy, and have got, methinks, so much the better of my disease. And I have yet less need of a notary or counsellor than of a physician.

As we passed under the last bridge over the canal, just before reaching the Merrimack, the people coming out of church paused to look at us from above, and apparently, so strong is custom, indulged in some heathenish comparisons; but we were the truest observers of this sunny day.

I had hoped that out of so many stories you would at least have produced one or two, which could hardly be questioned, and which would clearly show that ghosts or spectres exist. The case you relate... seems to me laughable. In like manner it would be tedious here to examine all the stories of people, who have written on these trifles. To be brief, I cite the instance of Julius Caesar, who, as Suetonius testifies, laughed at such things and yet was happy. ...And so should all who reflect on the human imagination, and the effects of the emotions, laugh at such notions; whatever Lavater and others, who have gone dreaming with him in the matter, may produce to the contrary.

He who carries self-regard far enough to keep himself in good health and high spirits, in the first place thereby becomes an immediate source of happiness to those around, and in the second place maintains the ability to increase their happiness by altruistic actions. But one whose bodily vigour and mental health are undermined by self-sacrifice carried too far, in the first place becomes to those around a cause of depression, and in the second place renders himself incapable, or less capable, of actively furthering their welfare. In estimating conduct we must remember that there are those who by their joyousness beget joy in others, and that there are those who by their melancholy cast a gloom on every circle they enter.

Once a word has been allowed to escape, it cannot be recalled.

I have always taken as the standard of the mode of teaching and writing, not the abstract, particular, professional philosopher, but universal man, that I have regarded man as the criterion of truth, and not this or that founder of a system, and have from the first placed the highest excellence of the philosopher in this, that he abstains, both as a man and as an author, from the ostentation of philosophy, i.e., that he is a philosopher only in reality, not formally, that he is a quiet philosopher, not a loud and still less a brawling one.

The more cunning a man is, the less he suspects that he will be caught in a simple thing. The more cunning a man is, the simpler the trap he must be caught in.

The people reign over the American political world as God rules over the universe. It is the cause and the end of all things; everything rises out of it and is absorbed back into it.

Rest gives relish to labour.

Everyone who knows anything of history also knows that great social revolutions are impossible without the feminine ferment. Social progress may be measured precisely by the social position of the fair sex (plain ones included).

Out of love, God becomes man. He says: Here you see what it is to be a human being; but he adds: Take care, for I am also God - blessed is he who takes no offense at me.
