When our Lord and Master Jesus Christ said, "Repent," he willed the entire life of believers to be one of repentance.

In actions of enthusiasm, this drawback appears: but in those lower activities, which have no higher aim than to make us more comfortable and more cowardly, in actions of cunning, actions that steal and lie, actions that divorce the speculative from the practical faculty, and put a ban on reason and sentiment, there is nothing else but drawback and negation.

But there is nothing sweeter than to dwell in towers that rise On high, serene and fortified with teachings of the wise, From which you may peer down upon the others as they stray This way and that, seeking the path of life, losing their way: The skirmishing of wits, the scramble for renown, the fight, Each striving harder than the next, and struggling day and night, To climb atop a heap of riches and lay claim to might.

I have resolved to demonstrate by a certain and undoubted course of argument, or to deduce from the very condition of human nature, not what is new and unheard of, but only such things as agree best with practice.

Do not commence your exercises in philosophy in those regions where an error can deliver you over to the executioner.

The sense in which an automatic door "understands instructions" from its photoelectric cell is not at all the sense in which I understand English.

With all our boasted reforms, our great social changes, and our far-reaching discoveries, human beings continue to be sent to the worst of hells, wherein they are outraged, degraded, and tortured, that society may be "protected" from the phantoms of its own making.

Single-mindedness is all very well in cows or baboons; in an animal claiming to belong to the same species as Shakespeare it is simply disgraceful.

In all determinations of morality, this circumstance of public utility is ever principally in view; and wherever disputes arise, either in philosophy or common life, concerning the bounds of duty, the question cannot, by any means, be decided with greater certainty, than by ascertaining, on any side, the true interests of mankind. If any false opinion, embraced from appearances, has been found to prevail; as soon as farther experience and sounder reasoning have given us juster notions of human affairs, we retract our first sentiment, and adjust anew the boundaries of moral good and evil.

That I should by necessity be either wise and good, or foolish or vicious, without having in one case or the other merit or fault - this it was that filled me with aversion and horror.The determination of my actions by a cause out of myself, whose manifestations were again determined by other causes - this it was from which I so violently revolted.The freedom which was not mine, but that of a foreign power, and, in that, only a conditional, half freedom - this it was with which I could not rest satisfied. I myself - that which in this system only appears as the manifestation of a higher existence, I will be independent, - will be something, not by another or through another, but of myself.

There is no more mistaken path to happiness than worldliness, revelry, high life.

If this is philosophy it is at any rate a philosophy that is not in its right mind.

Our conviction that the world is meaningless is due in part to the fact (discussed in a later paragraph) that the philosophy of meaningless lends itself very effectively to furthering the ends of political and erotic passion; in part to a genuine intellectual error - the error of identifying the world of science, a world from which all meaning has deliberately been excluded, with ultimate reality.

If you are a preacher of mercy, do not preach an imaginary but the true mercy. If the mercy is true, you must therefore bear the true, not an imaginary sin. God does not save those who are only imaginary sinners. Be a sinner, and let your sins be strong (sin boldly), but let your trust in Christ be stronger, and rejoice in Christ who is the victor over sin, death, and the world. We will commit sins while we are here, for this life is not a place where justice resides. We, however, says Peter (2. Peter 3:13) are looking forward to a new heaven and a new earth where justice will reign.

It is better to risk sparing a guilty person than to condemn an innocent one.

I wonder why I bother to tell the truth when people ask me what I think of this and that and how I feel about this and that. I get so complicated and introspective that people often don't understand and are frankly puzzled and (naturally enough) bored. So why bother! It would be so much easier to say what they expected you to, and everything would be easy and pleasant.

Science must begin with myths, and with the criticism of myths.

Incorporeal hypostases, in descending, are distributed into parts, and multiplied about individuals with a diminution of power; but when they ascend by their energies beyond bodies, they become united, and proceed into a simultaneous subsistence, through exuberance of power.

There are two distinct classes of men in the nation, those who pay taxes, and those who receive and live upon the taxes.

And every man, in love or pride, Of his fate is ever wide.

A word, once dissected, no longer signifies anything, is nothing. Like a body that, after an autopsy, is less than a corpse.

Pragmatism, in trying to turn experimental physics into a prototype of all science and to model all spheres of intellectual life after the techniques of the laboratory, is the counterpart of modern industrialism, for which the factory is the prototype of human existence, and which models all branches of culture after production on the conveyor belt.

It is better to live under a tree in a jungle inhabited by tigers and elephants, to maintain oneself in such a place with ripe fruits and spring water, to lie down on grass and to wear the ragged barks of trees than to live amongst one's relations when reduced to poverty.

To talk about religion except in terms of human psychology is an irrelevance.

But such is the nature of the human mind, that it always lays hold on every mind that approaches it; and as it is wonderfully fortified by an unanimity of sentiments, so is it shocked and disturbed by any contrariety. Hence the eagerness, which most people discover in a dispute; and hence their impatience of opposition, even in the most speculative and indifferent opinions.

The best definition of man is: a being that goes on two legs and is ungrateful.

It takes two to speak the truth, - one to speak, and another to hear.

Mathematics would certainly have not come into existence if one had known from the beginning that there was in nature no exactly straight line, no actual circle, no absolute magnitude.

The French are ... the most brilliant and the most dangerous nation of Europe, and the one that is surest to inspire admiration, hatred, terror, or pity, but never indifference.

Men of learning are those who have read the contents of books. Thinkers, geniuses, and those who have enlightened the world and furthered the race of men, are those who have made direct use of the book of the world.

All that is not eternal is eternally out of date.

To convince someone of the truth, it is not enough to state it, but rather one must find the path from error to truth.

The only man for whom Hitler had "unqualified respect" was "Stalin the genius," and while in the case of Stalin and the Russian regime we do not... have the rich documentary material that is available for Germany, we nevertheless know since Khrushchev's speech before the Twentieth Party Congress that Stalin trusted only one man and that was Hitler.

Paradise on earth is where I am.

Our aim as scientists is objective truth; more truth, more interesting truth, more intelligible truth. We cannot reasonably aim at certainty. Once we realize that human knowledge is fallible, we realize also that we can never be completely certain that we have not made a mistake.

They who bow to the enemy abroad will not be of power to subdue the conspirator at home.

The liar is a person who uses the valid designations, the words, in order to make something which is unreal appear to be real. He says, for example, "I am rich," when the proper designation for his condition would be "poor." He misuses fixed conventions by means of arbitrary substitutions or even reversals of names. If he does this in a selfish and moreover harmful manner, society will cease to trust him and will thereby exclude him. What men avoid by excluding the liar is not so much being defrauded as it is being harmed by means of fraud. Thus, even at this stage, what they hate is basically not deception itself, but rather the unpleasant, hated consequences of certain sorts of deception. It is in a similarly restricted sense that man now wants nothing but truth: he desires the pleasant, life-preserving consequences of truth. He is indifferent toward pure knowledge which has no consequences; toward those truths which are possibly harmful and destructive he is even hostilely inclined.

To regiment artists, to make them servants of some particular cause does violence to the very springs of artistic creation. But it does more than that. It betrays the very cause of a better future it would serve, for in its subjugation of the individuality of the artist it annihilates the source of that which is genuinely new. Where the regimentation is successful, it would cause the future to be but a rearrangement of the past.

I have been overcome by the beauty and richness of our life together, those early mornings setting out, those evenings gleaming with rivers and lakes below us, still holding the last light. ... Those fields of daisies we landed on, and dusty fields and desert stretches. Memories of many skies and earths beneath us - many days, many nights of stars.

Those who read and rightly understand my teaching will not start an insurrection; they have not learned that from me.

Doing what is for the good of the people, this must be the truest criterion of right government, in accordance with which the wise and good man will govern the affairs of his subjects. Just as the captain of a ship keeps watch for what is at any moment for the good of the vessel and the sailors, not by writing rules, but by making his science his law, and thus preserves his fellow voyagers, so may not a right government be established in the same way by men who could rule by this principle, making science more powerful than the laws? And whatever the wise rulers do, they can commit no error, so long as they maintain one great principle and by always dispensing absolute justice to them with wisdom and science are able to preserve the citizens and make them better than they were, so far as that is possible.

The native and untaught suggestions of inquisitive children do often offer things, that may set a considering man's thoughts on work. And I think there is frequently more to be learn'd from the unexpected questions of a child than the discourses of men, who talk in a road, according to the notions they have borrowed, and the prejudices of their education.

Owing to the identification of religion with virtue, together with the fact that the most religious men are not the most intelligent, a religious education gives courage to the stupid to resist the authority of educated men, as has happened, for example, where the teaching of evolution has been made illegal. So far as I can remember, there is not one word in the Gospels in praise of intelligence; and in this respect ministers of religion follow gospel authority more closely than in some others.

Station, power, wealth-how inadequate they have proved! How useless and insecure!

People don't stop things they enjoy doing just because they reach a certain age. They don't stop playing tennis just because they turn 40, they don't stop with sex just because they turn 40; they keep it up as long as they can if they enjoy it, and learning will be the same thing.

Hegel once observed that comedy is in act superior to tragedy and humourous reasoning superior to grandiloquent reasoning. Although Lincoln does not possess the grandiloquence of historical action, as an average man of the people he has its humour.

Nothing less will content me, than whole America.

Given our anthropocentric bias, thinking of non-human vertebrates not just as equivalent in moral status to toddlers or infants, but as though they were toddlers or infants, is a useful exercise. Such reconceptualisation helps correct our lack of empathy for sentient beings whose physical appearance is different from "us". Ethically, the practice of intelligent "anthropomorphism" shouldn't be shunned as unscientific, but embraced insofar as it augments our stunted capacity for empathy. Such anthropomorphism can be a valuable corrective to our cognitive and moral limitations. This is not a plea to be sentimental, simply for impartial benevolence.

Three passions, simple but overwhelmingly strong, have governed my life: the longing for love, the search for knowledge, and unbearable pity for the suffering of mankind. These passions, like great winds, have blown me hither and thither, in a wayward course, over a deep ocean of anguish, reaching to the very verge of despair.

I am sorry to say that at the moment I am so busy as to be convinced that life has no meaning whatever... I do not see that we can judge what would be the result of the discovery of truth, since none has hitherto been discovered.
