It is only afterward that a new idea seems reasonable. To begin with, it usually seems unreasonable.

I believe that the man choosing progress can find a new unity through the full development of all his human forces, which are produced in three orientations. These can be presented separately or together: biophilia, love for humanity and nature, and independence and freedom.

From another side: is Achilles possible with powder and lead? Or the Iliad with the printing press, not to mention the printing machine? Do not the song and saga of the muse necessarily come to an end with the printer's bar, hence do not the necessary conditions of epic poetry vanish?

The first intellectual operation in which I arrived at any proficiency, was dissecting a bad argument, and finding in what part the fallacy lay: and though whatever capacity of this sort I attained was due to the fact that it was an intellectual exercise in which I was most perseveringly drilled by my father, yet it is also true that the school logic, and the mental habits acquired in studying it, were among the principal instruments of this drilling. I am persuaded that nothing, in modern education, tends so much, when properly used, to form exact thinkers, who attach a precise meaning to words and propositions, and are not imposed on by vague, loose, or ambiguous terms. The boasted influence of mathematical studies is nothing to it; for in mathematical processes, none of the real difficulties of correct ratiocination occur.

Psychoanalysis, which interprets the human being as a socialized being, and the psychic apparatus as essentially developed and determined through the relationship of the individual to society, must consider it a duty to participate in the investigation of sociological problems to the extent the human being or his/her psyche plays any part at all.

To care only for well-being seems to me positively ill-bred. Whether it's good or bad, it is sometimes very pleasant, too, to smash things.

The way in which the vast mass of the poor are treated by modern society is truly scandalous. They are herded into great cities where they breathe a fouler air than in the countryside which they have left.

Alonso of Aragon was wont to say in commendation of age, that age appears to be best in four things - old wood best to burn, old wine to drink, old friends to trust, and old authors to read.

Love truth, but pardon error.

Most of the propositions that make up the body of administrative theory today share, unfortunately, this defect of proverbs. For almost every principle one can find an equally plausible and acceptable contradictory principle.

The divine life that underlies all appearance reveals itself never as a fixed and known entity, but as something that is to be; and after it has become what it was to be, it will reveal itself again to all eternity as something that is to be.

Man is free at the instant he wants to be.

What we really long for after death is to go on living this life, this same mortal life, but without its ills without its tedium, and without death. Seneca, the Spaniard, gave expression to this in his Consolatio ad Marciam... And what but that is the meaning of that comic conception of the eternal recurrence which issued from the tragic soul of poor Nietzsche, hungering for concrete and temporal immortality?

There are questions which, once approached, either isolate you or kill you outright.

I think of death only with tranquility, as an end. I refuse to let death hamper life. Death must enter life only to define it.

Truth and clarity are complementary.

When we have undermined the patriotic lie, we shall have cleared the path for that great structure wherein all nationalities shall be united into a universal brotherhood, - a truly FREE SOCIETY.

While there may exist no more than the normal extent of disagreement about the meaning of particular terms or theses contained in these works, there is a startling degree of divergence about the central view, the basic political attitude of Machiavelli.

His master was angry, and delivered him to the torturers until he should pay all that was due to him. "So My heavenly Father also will do to you if each of you, from his heart, does not forgive his brother his trespasses."

You have heard that it was said, "Eye for eye, and tooth for tooth." But I tell you, do not resist an evil person. If someone strikes you on the right cheek, turn to him the other also. And if someone wants to sue you and take your tunic, let him have your cloak as well. If someone forces you to go one mile, go with him two miles.

There is as much difference between us and ourselves as between us and others.

I know my heart, and have studied mankind; I am not made like any one I have been acquainted with, perhaps like no one in existence; if not better, I at least claim originality, and whether Nature did wisely in breaking the mould with which she formed me, can only be determined after having read this work. 

I regard you with an indifference closely bordering on aversion.

When there is genuine artistry in scientific inquiry and philosophic speculation, a thinker proceeds neither by rule nor yet blindly, but by means of meaning that exist immediately as feelings having qualitative color.

Every attempt to refer chemical questions to mathematical doctrines must be considered, now and always, profoundly irrational, as being contrary to the nature of the phenomena. . . . but if the employment of mathematical analysis should ever become so preponderant in chemistry (an aberration which is happily almost impossible) it would occasion vast and rapid retrogradation....

A man must always live by his work, and his wages must at least be sufficient to maintain him. They must even upon most occasions be somewhat more, otherwise it would be impossible for him to bring up a family, and the race of such workmen could not last beyond the first generation.

What nationalist educators often fail to recognize is that merely being taught by teachers who are black has not and will not solve the problem if the teachers have been socialized to internalize racist thinking.

As geological time goes, it is but a moment since the human race began and only the twinkling of an eye since the arts of civilization were first invented. In spite of some alarmists, it is hardly likely that our species will completely exterminate itself. And so long as man continues to exist, we may be pretty sure that, whatever he may suffer for a time, and whatever brightness may be eclipsed, he will emerge sooner or later, perhaps strengthened and reinvigorated by a period of mental sleep. The universe is vast and men are but tiny specks on an insignificant planet. But the more we realize our minuteness and our impotence in the face of cosmic forces, the more astonishing becomes what human beings have achieved.

We may define "faith" as a firm belief in something for which there is no evidence. Where there is evidence, no one speaks of "faith". We do not speak of faith that two and two are four or that the earth is round. We only speak of faith when we wish to substitute emotion for evidence. The substitution of emotion for evidence is apt to lead to strife, since different groups substitute different emotions.

To the mind of the ancients, who knew something of such matters, liberty and prosperity seemed hardly compatible, yet modern liberalism wants them together.

He [God] lends us a little of His reasoning powers and that is how we think: He puts a little of His love into us and that is how we love one another. When you teach a child writing, you hold its hand while it forms the letters: that is, it forms the letters because you are forming them. We love and reason because God loves and reasons and holds our hand while we do it.

History is the life of nations and of humanity. To seize and put into words, to describe directly the life of humanity or even of a single nation, appears impossible.

Despise all those things which when liberated from the body you will not want; invoke the Gods to become your helpers.

The farther men get from God, the farther they advance into the knowledge of religions.

I shall develop the thesis that anyone acting communicatively must, in performing any speech act, raise universal validity claims and suppose that they can be vindicated.

We must wish either for that which actually exists or for that which cannot in any way exist - or, still better, for both. That which is and that which cannot be are both outside the realm of becoming.

As for types like my own, obscurely motivated by the conviction that our existence was worthless if we didn't make a turning point of it, we were assigned to the humanities, to poetry, philosophy, painting - the nursery games of humankind, which had to be left behind when the age of science began. The humanities would be called upon to choose a wallpaper for the crypt, as the end drew near.

The more you obey your conscience, the more your conscience will demand of you.

At the speed of light there is no sequence; everything happens at the same instant.

Now shall we say that only the first men were well alive, and the existing generation is invalided and degenerate? ... A more subtle and severe criticism might suggest that some dislocation has befallen the race; that men are off their centre; that multitudes of men do not live with Nature, but behold it as exiles. People go out to look at sunrises and sunsets who do not recognize their own quietly and happily, but know that it is foreign to them. As they do by books, so they quote the sunset and the star, and do not make them theirs. Worse yet, they live as foreigners in the world of truth, and quote thoughts, and thus disown them. Quotation confesses inferiority.

If I work incessantly to the last, nature owes me another form of existence when the present one collapses.

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.

If one thing goes without saying, almost anything can.

This is the worst trait of minds rendered arrogant by prosperity, they hate those whom they have injured.

The man who holds the divine theory of life recognizes life not in his own individuality, and not in societies of individualities (in the family, the clan, the nation, the tribe, or the government), but in the eternal undying source of life-in God; and to fulfill the will of God he is ready to sacrifice his individual and family and social welfare. The motor power of his life is love. And his religion is the worship in deed and in truth of the principle of the whole-God.

When Philip had news brought him of divers and eminent successes in one day, "O Fortune!" said he, "for all these so great kindnesses do me some small mischief."

Mathematics, rightly viewed, possesses not only truth, but supreme beauty - a beauty cold and austere, like that of sculpture, without appeal to any part of our weaker nature, without the gorgeous trappings of painting or music, yet sublimely pure, and capable of a stern perfection such as only the greatest art can show. The true spirit of delight, the exaltation, the sense of being more than Man, which is the touchstone of highest excellence, is to be found in mathematics as surely as in poetry. What is best in mathematics deserves not merely to be learnt as a task, but to be assimilated as a part of daily thought, and brought again and again before the mind with ever-renewed encouragement.

The great secret of success is to go through life as a man who never gets used up. That is possible for him who never argues and strives with men and facts, but in all experience retires upon himself, and looks for the ultimate cause of things in himself.
