Audacity augments courage; hesitation, fear.

There remains the final reflection, how shallow, puny, and imperfect are efforts to sound the depths in the nature of things. In philosophical discussion, the merest hint of dogmatic certainty as to finality of statement is an exhibition of folly.

I have no need to take up each thing that wants to throw its cause on us and show that it is occupied only with itself, not with us, only with its good, not with ours. Look at the rest for yourselves. Do truth, freedom, humanity, justice, desire anything else than that you grow enthusiastic and serve them?

In this third period (as it may be termed) of my mental progress, which now went hand in hand with hers, my opinions gained equally in breadth and depth, I understood more things, and those which I had understood before, I now understood more thoroughly. I had now completely turned back from what there had been of excess in my reaction against Benthamism. I had, at the height of that reaction, certainly become much more indulgent to the common opinions of society and the world, and more willing to be content with seconding the superficial improvement which had begun to take place in those common opinions, than became one whose convictions on so many points, differed fundamentally from them. I was much more inclined, than I can now approve, to put in abeyance the more decidedly heretical part of my opinions, which I now look upon as almost the only ones, the assertion of which tends in any way to regenerate society.

Meditate upon my counsels; love them; follow them; To the divine virtues will they know how to lead thee. I swear it by the One who in our hearts engraved The sacred Tetrad, symbol immense and pure, Source of Nature and model of the Gods.

If I compare arithmetic with a tree that unfolds upward into a multitude of techniques and theorems while its root drives into the depths, then it seems to me that the impetus of the root.

It's better to bet on this life than on the next.

And above all, we must feel and act as if an endless continuation of our earthly life awaited us after death; and if it be that nothingness is the fate that awaits us we must not, in the words of Obermann, so act that it shall be a just fate.

Everything great glitters, glitter begets ambition, and ambition can easily have caused the inspiration or what we thought to be inspiration. But reason can no longer restrain one who is lured by the fury of ambition. He tumbles where his vehement drive calls him; no longer does he choose his position, but rather chance and luster determine it.

So long as men worship the Caesars and Napoleons, Caesars and Napoleons will duly rise and make them miserable.

Do you see this egg? With this you can topple every theological theory, every church or temple in the world. What is it, this egg, before the seed is introduced into it? An insentient mass. And after the seed has been introduced to into it? What is it then? An insentient mass. For what is the seed itself other than a crude and inanimate fluid? How is this mass to make a transition to a different structure, to sentience, to life? Through heat. And what will produce that heat in it? Motion. "Conversation Between D'Alembert and Diderot", as quoted in Selected Writings (1966) edited by Lester G. Crocker, and The Enlightenment and the Intellectual Foundations of Modern Culture (2004) by Louis K Dupré, p. 30 Variant translation: See this egg. It is with this that all the schools of theology and all the temples of the earth are to be overturned.

The standard bearers have grown weak in the defense of their priceless heritage, and the powers of darkness have been strengthened thereby. Weakness of attitude becomes weakness of character; it becomes lack of power to act with courage proportionate to danger. All this must lead to the destruction of our intellectual life unless the danger summons up strong personalities able to fill the lukewarm and discouraged with new strength and resolution.

Nothing makes one old so quickly as the ever-present thought that one is growing older.

As the neurobiological basis of feeling and emotion is unravelled, and the human genome decoded and rewritten, it will become purely an issue of post-human decision whether negative modes of consciousness are generated in any form or texture whatsoever. "The Hedonistic Imperative: Heaven on Earth", BLTC Research

Nor is prescription of government formed upon blind unmeaning prejudices-for man is a most unwise, and a most wise, being. The individual is foolish. The multitude, for the moment, is foolish, when they act without deliberation; but the species is wise, and when time is given to it, as a species it almost always acts right.

The first and most necessary topic in philosophy is that of the use of moral theorems, such as, "We ought not to lie;" the second is that of demonstrations, such as, "What is the origin of our obligation not to lie;" the third gives strength and articulation to the other two, such as, "What is the origin of this is a demonstration." For what is demonstration? What is consequence? What contradiction? What truth? What falsehood? The third topic, then, is necessary on the account of the second, and the second on the account of the first. But the most necessary, and that whereon we ought to rest, is the first. But we act just on the contrary. For we spend all our time on the third topic, and employ all our diligence about that, and entirely neglect the first.

Thus, all unknown quantities can be expressed in terms of a single quantity, whenever the problem can be constructed by means of circles and straight lines, or by conic sections, or even by some other curve of degree not greater than the third or fourth.But I shall not stop to explain this in more detail, because I should deprive you of the pleasure of mastering it yourself, as well as of the advantage of training your mind by working over it, which is in my opinion the principal benefit to be derived from this science. Because, I find nothing here so difficult that it cannot be worked out by anyone at all familiar with ordinary geometry and with algebra, who will consider carefully all that is set forth in this treatise.

I am in no way facetious, nor disposed for the mirth and galliardize of company, yet in one dream I can compose a whole Comedy, behold the action, apprehend the jests, and laugh myself awake at the conceits thereof.

Aristodemus, a friend of Antigonus, supposed to be a cook's son, advised him to moderate his gifts and expenses. "Thy words," said he, "Aristodemus, smell of the apron."

There is philosophy, which is about conceptual analysis - about the meaning of what we say - and there is all of this ... all of life.

This avidity alone, of acquiring goods and possessions for ourselves and our nearest friends, is insatiable, perpetual, universal, and directly destructive of society.

The truth is that the State is a conspiracy designed not only to exploit, but above all to corrupt its citizens ... Henceforth, I shall never serve any government anywhere.

... I once shook hands with Longfellow at a garden party in 1881; and I often saw Dr. Holmes, who was our neighbor in Beacon Street: but Emerson I never saw.

It is the fate of every truth to be an object of ridicule when it is first acclaimed. It was once considered foolish to suppose that black men were really human beings and ought to be treated as such. What was once foolish has now become a recognized truth. Today it is considered as exaggeration to proclaim constant respect for every form of life as being the serious demand of a rational ethic. But the time is coming when people will be amazed that the human race existed so long before it recognized that thoughtless injury to life is incompatible with real ethics. Ethics is in its unqualified form extended responsibility to everything that has life.

For in every country of the world, I believe, the avarice and injustice of princes and sovereign states, abusing the confidence of their subjects, have by degrees diminished the real quantity of metal, which had been originally contained in their coins.

You venerate the saints, and you take pleasure in touching their relics. But you disregard their greatest legacy, the example of a blameless life. No devotion is more pleasing to Mary than the imitation of Mary's humility. No devotion is more acceptable and proper to the saints than striving to imitate their virtues.

You need to know at least one foreign language well enough so that you can read the best literature that that language has produced in the original, and so you carry on a reasonable conversation and have dreams in that language. There are several reasons why this is crucial, but the most important is perhaps this: you can never understand one language until you understand at least two.

From the Christian point of view it stands firm that the truly Christian venturing requires probability.

Nothing has such power to broaden the mind as the ability to investigate systematically and truly all that comes under thy observation in life.

A real man is he whose goodness is a part of himself.

Only when they must choose between competing theories do scientists behave like philosophers.

Free-market fundamentalism trivializes the concern for public interest. It puts fear and insecurity in the hearts of anxiety-ridden workers. It also makes money-driven, poll-obsessed elected officials deferential to corporate goals of profit - often at the cost of the common good. ... The free-market fundamentalism that prevails in the United States today promotes the pervasive sleepwalking of the populace. People see that the false prophets are handsomely rewarded - with money, status and access to more power. ... We are experiencing the sad gangsterization of America - an unbridled grasp at power, wealth and status.

I don't care for the applause one gets by saying what others are thinking; I want actually to change people's thoughts. Power over people's minds is the main personal desire of my life; and this sort of power is not acquired by saying popular things.

It seems hard for the American people to believe that anything could be more exciting than the times themselves. What we read daily and view on the TV has thrust imagined forms into the shadow. We are staggeringly rich in facts, in things, and perhaps, like the nouveau riche of other ages, we want our wealth faithfully reproduced by the artist.

The river of my title is a river of DNA, and it flows through time, not space. It is a river of information, not a river of bones and tissues.

Northward of the Chesapeak you may find here and there an opponent to your doctrine as you may find here and there a robber and a murderer, but in no greater number. In that part of America, there being but few slaves, they can easily disencumber themselves of them, and emancipation is put into such a train that in a few years there will be no slaves Northward of Maryland. In Maryland I do not find such a disposition to begin the redress of this enormity as in Virginia. This is the next state to which we may turn our eyes for the interesting spectacle of justice in conflict with avarice and oppression: a conflict wherein the sacred side is gaining daily recruits from the influx into office of young men grown and growing up. These have sucked in the principles of liberty as it were with their mother's milk, and it is to them I look with anxiety to turn the fate of this question.

I shall cheerfully bear the reproach of having descended below the dignity of history if I can succeed in placing before the English of the nineteenth century a true picture of the life of their ancestors.

Our blight is ideologies - they are the long-expected Antichrist!

Your first duty, in completing your service to your race, is to feel within you all your ancestors. Your second duty is to throw light on their onrush and to continue their work. Your third duty is to pass on to your son the great mandate to surpass you.

We cannot ask ourselves whether 'woman' is superior or inferior to 'man' any more than we can ask ourselves whether water is superior or inferior to fire. There can be no doubt that a woman who is perfectly woman is superior to a man who is imperfectly man, just as a farmer who is faithful to his land and performs his work perfectly is superior to a king who cannot do his own work.

It is at work everywhere, functioning smoothly at times, at other times in firs and starts . It breathes, it heats, it eats. It shits and fucks. What a mistake to have ever said the id. Everywhere it is machines- real ones, not figurative ones: machines driving other machines, machines being driven by other machines, with all the necessary couplings and connections. An organ-machine is plugged into an energy-source-machine: the one produces a flow that the other interrupts The breast is a machine that produces milk, and the mouth a machine coupled to it.
