As our acts and our thoughts are, so will our lives be.

Perhaps misguided moral passion is better than confused indifference.

Everyone who has left houses or brothers or sisters or father or mother or children or fields for my sake will receive a hundred times as much and will inherit eternal life.

The interventionists do not approach the study of economic matters with scientific disinterestedness. Most of them are driven by an envious resentment against those whose incomes are larger than their own. This bias makes it impossible for them to see things as they really are. For them the main thing is not to improve the conditions of the masses, but to harm the entrepreneurs and capitalists even if this policy victimizes the immense majority of the people.

Frenchmen, it was to the noise of hellish songs, the blasphemy of atheism, the cries of death, and the prolonged moans of slaughtered innocence, it was by the light of flames, on the debris of throne and altar, watered by the blood of the best of kings and an innumerable host of other victims, it was by the contempt of morality and the established faith, it was in the midst of every crime that your seducers and your tyrants founded what they call your liberty.

Examine the man who lives in misery because he does not shine above other men; who goes about producing himself, pruriently anxious about his gifts and claims; struggling to force everybody, as it were begging everybody for God's sake, to acknowledge him a great man, and set him over the heads of men! Such a creature is among the wretchedest sights seen under this sun. A great man? A poor morbid prurient empty man; fitter for the ward of a hospital, than for a throne among men. I advise you to keep out of his way. He cannot walk on quiet paths; unless you will look at him, wonder at him, write paragraphs about him, he cannot live. It is the emptiness of the man, not his greatness. Because there is nothing in himself, he hungers and thirsts that you would find something in him. In good truth, I believe no great man, not so much as a genuine man who had health and real substance in him of whatever magnitude, was ever much tormented in this way.

The Apostle Paul wants us to work with our hands in order to share with the needy (Ephesians 5:28). Notice that he could have said that we should work to support ourselves. But Paul says that we work to give to those in need. This is why caring for our body is also a Christian work. If the body is healthy and fit, we are able to work and save money that can be used to help those in need.

Life grants nothing to us mortals without hard work.

There are only Epicureans, either crude or refined; Christ was the most refined.

"They are slaves," people declare. Nay, rather they are men. "Slaves!" No, comrades. "Slaves!" No, they are unpretentious friends. "Slaves!" No, they are our fellow-slaves, if one reflects that Fortune has equal rights over slaves and free men alike.

Placing your stick at the end of the shadow of the pyramid, you made by the sun's rays two triangles, and so proved that the pyramid [height] was to the stick [height] as the shadow of the pyramid to the shadow of the stick.

All urgent calls he shall hear at once, but never put off; for when postponed, they will prove too hard or impossible to accomplish.

If the immediate creator of the universe be he who is proclaimed by Moses, then we hold nobler beliefs concerning him, inasmuch as we consider him to be the master of all things in general, but that there are besides national gods who are subordinate to him and are like viceroys of a king, each administering separately his own province; and, moreover, we do not make him the sectional rival of the gods whose station is subordinate to his. But if Moses first pays honour to a sectional god, and then makes the lordship of the whole universe contrast with his power, then it is better to believe as we do, and to recognise the God of the All, though not without apprehending also the God of Moses; this is better, I say, than to honour one who has been assigned the lordship over a very small portion, instead of the creator of all things.

Anyone who is not shocked by quantum theory has not understood it.

Invention is the mother of all necessities.

In the realm of physics it is perhaps only the theory of relativity which has made it quite clear that the two essences, space and time, entering into our intuition, have no place in the world constructed by mathematical physics. Colours are thus "really" not even æther-vibrations, but merely a series of values of mathematical functions in which occur four independent parameters corresponding to the three dimensions of space, and the one of time.

I seem to myself, among civilised men, an intruder, a troglodyte enamored of decrepitude, plunged into subversive prayers.

Ignorance is not a simple lack of knowledge but an active aversion to knowledge, the refusal to know, issuing from cowardice, pride or laziness of mind. 

The core of common culture is religion. Tribes survive and flourish because they have gods, who fuse many wills into a single will, and demand and reward the sacrifices on which social life depends.

I could never stand more than three months of dreaming at a time without feeling an irresistible desire to plunge into society. To plunge into society meant to visit my superior, Anton Antonich Syetochkin. He was the only permanent acquaintance I have had in my life, and I even wonder at the fact myself now. But I even went to see him only when that phase came over me, and when my dreams had reached such a point of bliss that it became essential to embrace my fellows and all mankind immediately. And for that purpose I needed at least one human being at hand who actually existed. I had to call on Anton Antonich, however, on Tuesday - his at-home day; so I always had to adjust my passionate desire to embrace humanity so that it might fall on a Tuesday.

The consciousness of a general idea has a certain "unity of the ego" in it, which is identical when it passes from one mind to another. It is, therefore, quite analogous to a person, and indeed, a person is only a particular kind of general idea.

If the awareness of our limitations begins to limit or to dim our value consciousness as well-as happens, for instance, in old age with regard to the values of youth-then we have already started the movement of devaluation which will end with the defamation of the world and all its values. Only a timely act of resignation can deliver us from this tendency toward self-delusion.

It is hard to believe that this simple truth is not understood by those leaders who forbid their followers to use effective contraceptive methods. They express a preference for 'natural' methods of population limitation, and a natural method is exactly what they are going to get. It is called starvation.

Only in thought is man a God; in action and desire we are the slaves of circumstance.

Blessed is the healthy nature; it is the coherent, sweetly co-operative, not incoherent, self-distracting, self-destructive one!

Make your educational laws strict and your criminal ones can be gentle; but if you leave youth its liberty you will have to dig dungeons for ages.

There are various, nay, incredible faiths; why should we be alarmed at any of them? What man believes, God believes.

The belief in unity that has fuelled so many utopian dreams is an effort to reconcile the irreconcilable that ends in repression. Berlin suggests we renounce this venerable faith, and learn how to live with intractable conflict.

How many of us are able to distinguish between the odors of noon and midnight, or of winter and summer, or of a windy spell and a still one? If man is so generally less happy in the cities than in the country, it is because all these variations and nuances of sight and smell and sound are less clearly marked and lost in the general monotony of gray walls and cement pavements.

There is no idea more novel, more surprising, than that of associating three hundred families of different degrees of fortune, knowledge and capacity.

I cannot escape the objection that there is no state of mind, however simple, that does not change every moment.

May it not be the fact that mankind, who after all are made up of single human beings, obtain a greater sum of happiness when each pursues his own, under the rules and conditions required by the good of the rest, than when each makes the good of the rest his only object, and allows himself no personal pleasures not indispensable to the preservation of his faculties? The regimen of a blockaded town should be cheerfully submitted to when high purposes require it, but is it the ideal perfection of human existence?

Now as of old the gods give men all good things, excepting only those that are baneful and injurious and useless. These, now as of old, are not gifts of the gods: men stumble into them themselves because of their own blindness and folly.

Press on, therefore, as you have begun; perhaps you will be led to perfection, or to a point which you alone understand is still short of perfection.

The chief function of the disciplinary power is to 'train', rather than to select and to levy; or, no doubt, to train in order to levy and select all the more. It does not link forces together in order to reduce them; it seeks to bind them together in such a way as to multiply and use them.

Social Democratic centralism cannot be based on the mechanical subordination and blind obedience of the party membership to the leading party center. The Social Democratic movement cannot allow the erection of an air-tight partition between the class-conscious nucleus of the proletariat already in the party and its immediate popular environment, the nonparty sections of the proletariat.

Man reaches the highest point of his knowledge about God when he knows that he knows him not, inasmuch as he knows that that which is God transcends whatsoever he conceives of him.

The subversive character of truth inflicts upon thought an imperative quality. Logic centers on judgments which are, as demonstrative propositions, imperatives, - the predicative "is" implies an "ought." ... Verification of the proposition involves a process in fact as well as in thought: (S) must become that which it is. The categorical statement thus turns into a categorical imperative; it does not state a fact but the necessity to bring about a fact. For example, it could be read as follows: man is not (in fact) free, endowed with inalienable rights, etc., but he ought to be.

How do you think the transition from the present situation to community of Property is to be effected? The first, fundamental condition for the introduction of community of property is the political liberation of the proletariat through a democratic constitution.

The music that can deepest reach, And cure all ill, is cordial speech.

Whereas the man of action binds his life to reason and its concepts so that he will not be swept away and lost, the scientific investigator builds his hut right next to the tower of science so that he will be able to work on it and to find shelter for himself beneath those bulwarks which presently exist. And he requires shelter, for there are frightful powers which continuously break in upon him, powers which oppose scientific "truth" with completely different kinds of "truths" which bear on their shields the most varied sorts of emblems.

That which Fortune has not given, she cannot take away.

Anyone wanting a new house picks one from among those built on speculation or still in process of construction. The builder no longer works for his customers but for the market.
