The necessity of speaking, the predicament of having nothing to say, and the desire for tact are three things that can turn the greatest man into a laughingstock.

The patient typically finds himself impelled by some deep, inner conviction that something is true, or right, or virtuous: a conviction that doesn't seem to owe anything to evidence or reason, but which, nevertheless, he feels as totally compelling and convincing. We doctors refer to such a belief as "faith".

It is true that every increase of knowledge may possibly render depravity more depraved, as well as it may increase the strength of virtue. It is in itself only power; and its value depends on its application.

Every book is a quotation; and every house is a quotation out of all forests and mines and stone-quarries; and every man is a quotation from all his ancestors.

Give us grace and strength to forbear and to persevere. Give us courage and gaiety and the quiet mind, spare to us our friends, soften to us our enemies.

There is no man so good that if he placed all his actions and thoughts under the scrutiny of the laws, he would not deserve hanging ten times in his life.

"I don't want to! Why should I?" "Because more people will be happier if you do than if you don't." "So what? I don't care about other people." "You should." "But why?" "Because more people will be happier if you do than if you don't."

Respect the child. Be not too much his parent. Trespass not on his solitude.

Accent is the soul of language; it gives to it both feeling and truth.

At fifteen my heart was set on learning; at thirty I stood firm; at forty I had no more doubts; at fifty I knew the will of heaven; at sixty my ear was obedient; at seventy I could follow my heart's desire without overstepping the boundaries of what was right.

The world is nothing but 'world-as-meaning.'

I trust that some may be as near and dear to Buddha, or Christ, or Swedenborg, who are without the pale of their churches. It is necessary not to be Christian to appreciate the beauty and significance of the life of Christ. I know that some will have hard thoughts of me, when they hear their Christ named beside my Buddha, yet I am sure that I am willing they should love their Christ more than my Buddha, for the love is the main thing, and I like him too.

History, if viewed as a repository for more than anecdote or chronology, could produce a decisive transformation in the image of science by which we are now possessed.

We took the liberty to make some enquiries concerning the ground of their pretensions to make war upon nations who had done them no injury, and observed that we considered all mankind as our friends who had done us no wrong, nor had given us any provocation. The Ambassador [of Tripoli] answered us that it was founded on the Laws of their Prophet, that it was written in their Koran, that all nations who should not have acknowledged their authority were sinners, that it was their right and duty to make war upon them wherever they could be found, and to make slaves of all they could take as Prisoners, and that every Musselman who should be slain in battle was sure to go to Paradise.

What has been shown by Machiavelli, who is often (like Nietzsche) congratulated for tearing off hypocritical masks, brutally revealing the truth, and so on, is not that men profess one thing and do another (although no doubt he shows this too) but that when they assume that the two ideals are compatible, or perhaps are even one and the same ideal, and do not allow this assumption to be questioned, they are guilty of bad faith (as the existentialists call it, or of "false consciousness," to use a Marxist formula) which their actual behavior exhibits. Machiavelli calls the bluff not just of official morality-the hypocrisies of ordinary life-but of one of the foundations of the central Western philosophical tradition, the belief in the ultimate compatibility of all genuine values. His own withers are unwrung. He has made his choice. He seems wholly unworried by, indeed scarcely aware of, parting company with traditional Western morality.

Things essentially incorporeal, because they are more excellent than all body and place, are every where, not with interval, but impartibly. Things essentially incorporeal are not locally present with bodies but are present with them when they please; by verging towards them so far as they are naturally adapted so to verge. They are not, however, present with them locally, but through habitude, proximity, and alliance. Things essentially incorporeal, are not present with bodies, by hypostasis and essence; for they are not mingled with bodies. But they impart a certain power which is proximate to bodies, through verging towards them. For tendency constitutes a certain secondary power proximate to bodies.

It (marriage) happens as with cages: the birds without despair to get in, and those within despair of getting out.

The inventive genius of great England will not forever sit patient with mere wheels and pinions, bobbins, straps and billy-rollers whirring in the head of it. The inventive genius of England is not a Beaver's, or a Spinner's or Spider's genius: it is a Man's genius, I hope, with a God over him!

What then? Shall I not follow in the footsteps of my predecessors? I shall indeed use the old road, but if I find one that makes a shorter cut and is smoother to travel, I shall open the new road. Men who have made these discoveries before us are not our masters, but our guides. Truth lies open for all; it has not yet been monopolized. And there is plenty of it left even for posterity to discover.

Whence do you have it that the terrestrial globe is so heavy? For my part, either I do not know what heaviness is, or the terrestrial globe is neither heavy nor light, as likewise all other globes of the universe. Heaviness to me (and I believe to Nature) is that innate tendency by which a body resists being moved from its natural place and by which, when forcibly removed therefrom, it spontaneously returns there. Thus a bucketful of water raised on high and set free, returns to the sea; but who will say that the same water remains heavy in the sea, when being set free there, does not move?

Treat your inferiors as you would be treated by your betters.

I sincerely rejoice at the acceptance of our new Constitution by nine States. It is a good canvas, on which some strokes only want retouching. What these are, I think are sufficiently manifested by the general voice from north to south, which calls for a bill of rights.

Victories over ingrained patterns of thought are not won in a day or a year.

Those who were best able to provide themselves with the means of security against their neighbors, being thus in possession of the surest guarantee, passed the most agreeable life in each other's society; and their enjoyment of the fullest intimacy was such that, if one of them died before his time, the survivors did not mourn his death as if it called for sympathy.

The only roads of enquiry there are to think of: one, that it is and that it is not possible for it not to be, this is the path of persuasion (for truth is its companion); the other, that it is not and that it must not be - this I say to you is a path wholly unknowable.

It seems to me that the current political task in a society like ours is to criticize the working of institutions that are apparently the most neutral and independent, to criticize these institutions and attack them in such a way that the political violence that exercises itself obscurely through them becomes manifest, so that one can fight against them.

People hate it when they're tickled because laughter is not pleasant, if it goes on too long. I think it's a desperate sort of convulsion in desperate circumstances, which helps a little.

Every artist was first an amateur.

I am well aware of how anarchic much of what I say may sound. Expressing myself thus abstractly and briefly, I may seem to despair of the very notion of truth. But I beseech you to reserve your judgment until we see it applied to the details which lie before us. I do indeed disbelieve that we or any other mortal men can attain on a given day to absolutely incorrigible and unimprovable truth about such matters of fact as those with which religions deal. But I reject this dogmatic ideal not out of a perverse delight in intellectual instability. I am no lover of disorder and doubt as such. Rather do I fear to lose truth by this pretension to possess it already wholly.

More controversially, technology can accelerate the transition from harming to helping free-living sentient beings: mankind's fitfully expanding "circle of compassion". The civilising process needn't be species-specific but instead extend to free-living dwellers in tomorrow's wildlife parks. Every cubic metre of the biosphere will soon be computationally accessible to surveillance, micro-management and control. Fertility regulation via immunocontraception can replace Darwinian ecosystems governed by starvation and predation. Any species of obligate carnivore we choose to preserve can be genetically and behaviourally tweaked into harmlessness. Asphyxiation, disembowelling, and agonies of being eaten alive can pass into the dustbin of history.

The foundation of all technology is fire.

Ambition is the death of thought.

We are aware of all the inconveniences of prison, and that it is dangerous when it is not useless. And yet one cannot 'see' how to replace it. It is the detestable solution, which one seems unable to do without.

The peculiar and amusing nature of those answers stems from the fact that modern history is like a deaf person who is in the habit of answering questions that no one has put to them. If the purpose of history be to give a description of the movement of humanity and of the peoples, the first question - in the absence of a reply to which all the rest will be incomprehensible - is: what is the power that moves peoples? To this, modern history laboriously replies either that Napoleon was a great genius, or that Louis XIV was very proud, or that certain writers wrote certain books. All that may be so and mankind is ready to agree with it, but it is not what was asked.

Never let your sense of morals prevent you from doing what is right.

Discourses are tactical elements or blocks operating in the field of force relations; there can exist different and even contradictory discourses within the same strategy; they can, on the contrary, circulate without changing their form from one strategy to another, opposing strategy.

I am a pattern watcher.

I have never taken myself for a being. A non-citizen, a marginal type, a nothing who exists only by the excess, by the superabundance of his nothingness.

I neither deny nor affirm the immortality of man. I see no reason for believing in it, but, on the other hand, I have no means of disproving it.

While experiencing happiness, we have difficulty in being conscious of it. Only when the happiness is past and we look back on it we do suddenly realize - sometimes with astonishment - how happy we had been.

It is so hard to forget what it is worse than useless to remember! If I am to be a thoroughfare, I prefer that it be of the mountain-brooks, the Parnassian streams, and not the town-sewers. There is inspiration, that gossip which comes to the ear of the attentive mind from the courts of heaven. There is the profane and stale revelation of the bar-room and the police court. The same ear is fitted to receive both communications. Only the character of the hearer determines to which it shall be open, and to which closed. I believe that the mind can be permanently profaned by the habit of attending to trivial things, so that all our thoughts shall be tinged with triviality.

... happiness is not an ideal of reason, but of imagination, resting on merely empirical grounds…

There is no order between created being and non-being, but there is between created and uncreated being.

If I had had more time, this letter would have been shorter.

No one ever told me that grief felt so like fear. First line.

Women are the most charitable creatures, and the most troublesome. He who shuns women passes up the trouble, but also the benefits. He who puts up with them gains the benefits, but also the trouble. As the saying goes, there's no honey without bees.

Without consciousness there would, practically speaking, be no world, for the world exists as such only in so far as it is consciously reflected and considered by a psyche. Consciousness is a precondition of being.

Fear not, then, thou child infirm, There's no god dare wrong a worm.
