"Optimism," said Cacambo, "What is that?" "Alas!" replied Candide, "It is the obstinacy of maintaining that everything is best when it is worst!

When the empirical investigator glories in his refusal to go beyond the specialized observation dictated by the traditions of his discipline, be they ever so inclusive, he is making a virtue out of a defense mechanism which insures him against questioning his presuppositions.

The bourgeoisie hides the fact that it is the bourgeoisie and thereby produces myth; revolution announces itself openly as revolution and thereby abolishes myth.

If thou canst see sharp, look and judge wisely, says the philosopher.

From the nature and purpose of civil institutions, all the lands within the limits which any particular society has circumscribed around itself are assumed by that society, and subject to their allotment only. This may be done by themselves, assembled collectively, or by their legislature, to whom they may have delegated sovereign authority; and if they are alloted in neither of these ways, each individual of the society may appropriate to himself such lands as he finds vacant, and occupancy will give him title.

If you think that your belief is based upon reason, you will support it by argument, rather than by persecution, and will abandon it if the argument goes against you. But if your belief is based on faith, you will realize that argument is useless, and will therefore resort to force either in the form of persecution or by stunting and distorting the minds of the young in what is called "education". This last is particularly dastardly, since it takes advantage of the defencelessness of immature minds. Unfortunately it is practiced in greater or less degree in the schools of every civilised country.

Once for all, then, a short precept is given thee: Love, and do what thou wilt: whether thou hold thy peace, through love hold thy peace; whether thou cry out, through love cry out; whether thou correct, through love correct; whether thou spare, through love do thou spare: let the root of love be within, of this root can nothing spring but what is good.

I esteem myself happy to have as great an ally as you in my search for truth. I will read your work ... all the more willingly because I have for many years been a partisan of the Copernican view because it reveals to me the causes of many natural phenomena that are entirely incomprehensible in the light of the generally accepted hypothesis. To refute the latter I have collected many proofs, but I do not publish them, because I am deterred by the fate of our teacher Copernicus who, although he had won immortal fame with a few, was ridiculed and condemned by countless people (for very great is the number of the stupid).

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.

The poet is, etymologically, the maker. Like all makers, he requires a stock of raw materials - in his case, experience. Now experience is not a matter of having actually swum the Hellespont, or danced with the dervishes, or slept in a doss-house. It is a matter of sensibility and intuition, of seeing and hearing the significant things, of paying attention at the right moments, of understanding and co-ordinating. Experience is not what happens to a man; it is what a man does with what happens to him. It is a gift for dealing with the accidents of existence, not the accidents themselves. By a happy dispensation of nature, the poet generally possesses the gift of experience in conjunction with that of expression. What he says so well is therefore intrinsically of value.

The traditional disputes of philosophers are, for the most part, as unwarranted as they are unfruitful. The surest way to end them is to establish beyond question what should be the purpose and method of a philosophical enquiry. And this is by no means so difficult a task as the history of philosophy would lead one to suppose. For if there are any questions which science leaves it to philosophy to answer, a straightforward process of elimination must lead to their discovery.

But, in my state of mind, this appearance of superiority to illusion added to the effect which Bentham's doctrines produced on me, by heightening the impression of mental power, and the vista of improvement which he did open was sufficiently large and brilliant to light up my life, as well as to give a definite shape to my aspirations.

Virtue is reason which has become energy.

I conceive that the description so often given of a Benthamite, as a mere reasoning machine, though extremely inapplicable to most of those who have been designated by that title, was during two or three years of my life not altogether untrue of me. ...There is nothing very extraordinary in this fact: no youth of the age I then was, can be expected to be more than one thing, and this was the thing I happened to be. Ambition and desire of distinction, I had in abundance; and zeal for what I thought the good of mankind was my strongest sentiment, mixing with and colouring all others. But my zeal was as yet little else, at that period of my life, than zeal for speculative opinions. It had not its root in genuine benevolence, or sympathy with mankind; though these qualities held their due place in my ethical standard. Nor was it connected with any high enthusiasm for ideal nobleness.

Philosophy is the science of truth.

What is the use of believing, if the dost blaspheme? Thou adorest Him as Head, and dost blaspheme Him in His body. He loves His body. Thou canst cut thyself off from the body, but the Head does not detach itself from its body. "Thou dost honor me in vain," He cries from heaven, "thou dost honor Me in vain!" If someone wished to kiss thy cheek, but insisted at the same time on trampling thy feet; if with his hailed boots he were to crush thy feet as he tries to hold thy head and kiss thee, wouldst thou not interrupt his expression of respect and cry out: "What are thou doing, man? Thou art trampling upon me!" It is for this reason that before He ascended into heaven our Lord Jesus Christ recommended to us His body, by which He was to remain upon earth. For He foresaw that many would pay Him homage because of His glory in heaven, but that their homage would be vain, so long as they despise His members on earth.

Unpleasant, even dangerous, qualities can be found in every nation and every individual: it is cruel to demand that the Jew be an exception. In him, these qualities may even be dangerous and revolting to an unusual degree; and perhaps the young stock-exchange Jew is altogether the most disgusting invention of mankind.

Tsze-Kung asked Confucius, saying, "Master, are you a sage?" Confucius answered him: "A sage is what I cannot rise to. I learn without satiety, and teach without being tired." Tsze-Kung said: "You learn without satiety: that shows your wisdom. You teach without being tired: that shows your benevolence. Benevolent and wise:- Master, you are a sage."

My God and I are horsemen galloping in the burning sun or under drizzling rain. Pale, starving, but unsubdued, we ride and converse. "Leader!" I cry. He turns his face toward me, and I shudder to confront his anguish. Our love for each other is rough and ready, we sit at the same table, we drink the same wine in this low tavern of life.

That some have never dreamed is as improbable as that some have never laughed.

But men must know that in this theater of man's life it is reserved only for God and angels to be lookers on.

I have never worked as hard as now. I go for a brief walk in the morning. Then I come home and sit in my room without interruption until about three o'clock. My eyes can barely see. Then with my walking stick in hand I sneak off to the restaurant, but am so weak that I believe that if somebody were to call out my name, I would keel over and die. Then I go home and begin again. In my indolence during the past months I had pumped up a veritable shower bath, and now I have pulled the string and the ideas are cascading down upon me: healthy, happy, merry, gay, blessed children born with ease and yet all of them with the birthmark of my personality.

Behold, we go up to Jerusalem; and the Son of man shall be betrayed unto the chief priests and unto the scribes, and they shall condemn him to death, And shall deliver him to the Gentiles to mock, and to scourge, and to crucify him: and the third day he shall rise again.

It is generally agreed that no activity can be successfully pursued by an individual who is preoccupied - not rhetoric or liberal studies - since the mind when distracted absorbs nothing deeply, but rejects everything which is, so to speak, crammed into it.

Before either of us knew it, we belonged to each other.

How selfish soever man may be supposed, there are evidently some principles in his nature, which interest him in the fortune of others, and render their happiness necessary to him, though he derives nothing from it except the pleasure of seeing it.

Valor withers without adversity.

Things are not so painful and difficult of themselves, but our weakness or cowardice makes them so.

Men never respect what they have made themselves. This is why an elective king never possesses the moral power of a hereditary sovereign, because he is not noble enough, that is to say he does not possess that kind of greatness independent of men and that is the work of time.

Monarch of earth, I shall confess my secret craft:I've always fought to purify wild flame to light,and kindle whatever light I found to burst in flame.

But your crime will be there, one hundred times denied, always there, dragging itself behind you. Then you will finally know that you have committed your life with one throw of the die, once and for all, and there is nothing you can do but tug our crime along until your death. Such is the law, just and unjust, of repentance. Then we will see what will become of your young pride.

The meaning of relativity has been widely misunderstood. Philosophers play with the word, like a child with a doll. Relativity, as I see it, merely denotes that certain physical and mechanical facts, which have been regarded as positive and permanent, are relative with regard to certain other facts in the sphere of physics and mechanics. It does not mean that everything in life is relative and that we have the right to turn the whole world mischievously topsy-turvy.

Wonder is not a disease. Wonder, and its expression in poetry and the arts, are among the most important things which seem to distinguish men from other animals, and intelligent and sensitive people from morons.

The only progress I can see is progress in the organization. The ordinary human being does not live long enough to draw any substantial benefit from his own experience. And no one, it seems, can benefit by the experiences of others. Being both a father and teacher, I know we can teach our children nothing. We can transmit to them neither our knowledge of life nor of mathematics. Each must learn its lesson anew.

Every ideology is contrary to human psychology.

I am here to speak on freedom of speech. It is a great topic, and I am going to make my speech as free as possible. But you know that this cannot be done, for when anyone announces that he is going to speak his mind freely, everyone is frightened. This shows that there is no such thing as true freedom of speech. No one can afford to let his neighbors know what he is thinking about them. Society can exist only on the basis that there is some amount of polished lying and that no one says exactly what he thinks.

I want to be seen here in my simple, natural, ordinary fashion, without straining or artifice; for it is myself that I portray...I am myself the matter of my book. To the Reader

Whatever is known to us by consciousness, is known beyond possibility of question. What one sees or feels, whether bodily or mentally, one cannot but be sure that one sees or feels. No science is required for the purpose of establishing such truths; no rules of art can render our knowledge of them more certain than it is in itself. There is no logic for this portion of our knowledge.

A dangerous form of psychological splitting had to have taken place, and it continues to take place, in the psyches of many African Americans who can on one hand oppose racism, and then on the other hand passively absorb ways of thinking about beauty that are rooted in white supremacist thought.

When a man is in a fair way and sees all life open in front of him, he seems to himself to make a very important figure in the world. His horse whinnies to him; the trumpets blow and the girls look out of window as he rides into town before his company; he receives many assurances of trust and regard--sometimes by express in a letter--sometimes face to face, with persons of great consequence falling on his neck. It is not wonderful if his head is turned for a time. But once he is dead, were he as brave as Hercules or as wise as Solomon, he is soon forgotten.

The utility of a science which enables men to take cognizance of the travellers on the mind's highway, and excludes those disorderly interlopers, verbal fallacies, needs but small attestation. Its searching penetration by definition alone, before which even mathematical precision fails, would especially commend it to those whom the abstruseness of the study does not terrify, and who recognise the valuable results which must attend discipline of mind. Like a medicine, though not a panacea for every ill, it has the health of the mind for its aim, but requires the determination of a powerful will to imbibe its nauseating yet wholesome influence: it is no wonder therefore that puny intellects, like weak stomachs, abhor and reject it.

For those who want 'to change life", 'to reinvent love,' God is nothing but a hindrance.

Heroic love is the property of those superior natures who are called insane not because they do not know, but because they over-know.

By the rude bridge that arched the flood, Their flag to April's breeze unfurled, Here once the embattled farmers stood, And fired the shot heard round the world. The foe long since in silence slept; Alike the conqueror silent sleeps; And Time the ruined bridge has swept Down the dark stream which seaward creeps. On this green bank, by this soft stream, We set to-day a votive stone; That memory may their deed redeem, When, like our sires, our sons are gone. Spirit, that made those heroes dare, To die, and leave their children free, Bid Time and Nature gently spare The shaft we raise to them and thee.

All the world knows me in my book, and my book in me.

The Greek word for philosopher (philosophos) connotes a distinction from sophos. It signifies the lover of wisdom (knowledge) as distinguished from him who considers himself wise in the possession of knowledge. This meaning of the word still endures: the essence of philosophy is not the possession of the truth but the search for truth. ... Philosophy means to be on the way. Its questions are more essential than its answers, and every answer becomes a new question.

One day, we shall stand up and our backsides will remain attached to our seats.

He whom God has touched will always be a being apart: he is, whatever he may do, a stranger among men; he is marked by a sign.
