The friendship of one wise man is better than the friendship of a host of fools.

The belief in a political Utopia is especially dangerous. This is possibly connected with the fact that the search for a better world, like the investigation of our environment, is (if I am correct) one of the oldest and most important of all the instincts.

Virtue refuses facility for her companion ... the easy, gentle, and sloping path that guides the footsteps of a good natural disposition is not the path of true virtue. It demands a rough and thorny road.

The rush to California, for instance, and the attitude, not merely of merchants, but of philosophers and prophets, so called, in relation to it, reflect the greatest disgrace on mankind. That so many are ready to live by luck, and so get the means of commanding the labor of others less lucky, without contributing any value to society!

Science does not stand still, and neither does philosophy, although the latter has a tendency to walk in circles.

By far my greatest dread in life [...] is that (some variant of) the Everett interpretation of Quantum Mechanics is true. Dave's Diary, BLTC Research, May 1996

The reason a man lives under any particular government is partly a necessity; he cannot easily avoid living under some government, and it is often scarcely in his power to abandon the country in which he was born: it is also partly, a choice of evil; no man can be said, in this case, to enjoy that freedom which is essential to the forming a contract unless it could be shown that he had a power of instituting, somewhere, a government adapted to his own conceptions.

Ever, as before, does Madness remain a mysterious-terrific, altogether infernal boiling-up of the Nether Chaotic Deep, through this fair-painted Vision of Creation, which swims thereon, which we name the Real.

Above all, every relation must be considered as suspicious, which depends in any degree upon religion, as the prodigies of Livy: And no less so, everything that is to be found in the writers of natural magic or alchemy, or such authors, who seem, all of them, to have an unconquerable appetite for falsehood and fable.

Nobody is bound to have an optimistic outlook on the future: that is not a precept of the Christian religion. ... It is a matter of immense importance that illusions should be dispelled and man come face to face with positive realities.

Man's life cannot "be lived" by repeating the pattern of his species; he must live. Man is the only animal that can be bored, that can be discontented, that can feel evicted from paradise. Man is the only animal for whom his own existence is a problem which he has to solve and from which he cannot escape. He cannot go back to the prehuman state of harmony with nature; he must proceed to develop his reason until he becomes the master of nature, and of himself.

If you're certain, you're certainly wrong, because nothing deserves certainty.

I could show, that the same faction has, in one reign, promoted popular seditions, and, in the next, been a patron of tyranny; I could show, that they have all of them betrayed the public safety at all times, and have very frequently with equal perfidy made a market of their own cause, and their own associates. I could show how vehemently they have contended for names, and how silently they have passed over things of the last importance.

To shoot down a European is to kill two birds with one stone, to destroy an oppressor and the man he oppresses at the same time.

Ego is a social institution with no physical reality. The ego is simply your symbol of yourself. Just as the word "water" is a noise that symbolizes a certain liquid without being it, so too the idea of ego symbolizes the role you play, who you are, but it is not the same as your living organism.

Then we understand that rebellion cannot exist without a strange form of love. Those who find no rest in God or in history are condemned to live for those who, like themselves, cannot live; in fact, for the humiliated.

I don't think that there are any sinister persons deliberately trying to rob people of their freedom but I do think, first of all, that there are a number of impersonal forces which are pushing in the direction of less and less freedom. And I also thing there are a number of technological devices which anybody who wishes to use, can use, to accelerate this process of going away from freedom, of imposing control.

To all my friends without distinction I am ready to display my opulence: come one, come all; and whosoever likes to take a share is welcome to the wealth that lies within my soul.

The heterodox current in Judaism led by Jesus seems to have had no notion of an immortal soul, created by God and then infused into the body: immortality meant being raised from the dead in the body one had in life, then living for ever in a world without decay or corruption. In the Christian religion invented by Paul and Augustine, which was strongly influenced by Plato, immortality meant something quite different - a life out of time, enjoyed by the 'soul' or 'spirit' of the departed. How this Platonic immortality could preserve anything like the persons that once lived was not made clear.

They that be whole need not a physician, but they that are sick. But go ye and learn what that meaneth, I will have mercy, and not sacrifice: for I am not come to call the righteous, but sinners to repentance.

Hence money may be dirt, although dirt is not money.

With so many mind-bytes to be downloaded, so many mental codons to be replicated, it is no wonder that child brains are gullible, open to almost any suggestion, vulnerable to subversion, easy prey to Moonies, Scientologists and nuns. Like immune-deficient patients, children are wide open to mental infections that adults might brush off without effort.

It is remarkable, that almost all speakers and writers feel it to be incumbent on them, sooner or later, to prove or to acknowledge the personality of God. ... In reading a work on agriculture, we have to skip the author's moral reflections, and the words "Providence" and "He" scattered along the page, to come at the profitable level of what he has to say. What he calls his religion is for the most part offensive to the nostrils. ... There is more religion in men's science than there is science in their religion.

The old Romans had a custom which survived even into my lifetime. They would add to the opening words of a letter: "If you are well, it is well; I also am well." Persons like ourselves would do well to say. "If you are studying philosophy, it is well." For this is just what "being well" means. Without philosophy the mind is sickly.

Man cannot will unless he has first understood that he must count on no one but himself; that he is alone, abandoned on earth in the midst of his infinite responsibilities, without help, with no other aim than the one he sets himself, with no other destiny than the one he forges for himself on this earth.

At this point we find ourselves confronted by a very disquieting question: Do we really wish to act upon our knowledge?

Thus intrigues and conspiracies do not arise, and thievery and robbery do not occur; therefore doors need never be locked.

The union of the mathematician with the poet, fervor with measure, passion with correctness, this surely is the ideal.

No one ever saw Cato change, no matter how often the state changed: he kept himself the same in all circumstances-in the praetorship, in defeat, under accusation, in his province, on the platform, in the army, in death.

The punctuation of anniversaries is terrible, like the closing of doors, one after another between you and what you want to hold on to.

Logos is the formal cause of the kosmos and all things, responsible for their nature and configuration.

Each generation is a filter, a sieve; good genes tend to fall through the sieve into the next generation; bad genes tend to end up in bodies that die young or without reproducing.

When I was a boy, I had a clock with a pendulum that could be lifted off. I found that the clock went very much faster without the pendulum. If the main purpose of a clock is to go, the clock was the better for losing its pendulum. True, it could no longer tell the time, but that did not matter if one could teach oneself to be indifferent to the passage of time. The linguistic philosophy which cares only about language and not about the world, is like the boy who preferred the clock without the pendulum because, although it no longer told the time, it went more easily than before and at a more exhilarating pace.

The political freedom of conscience and of the press, so far from being as it is commonly supposed an extension, is a new case of the limitation of rights and discretion. Conscience and the press ought to be unrestrained, not because men have a right to deviate from the exact line that duty prescribes, but because society, the aggregate of individuals, has no right to assume the prerogative of an infallible judge, and to undertake authoritatively to prescribe to its members in matters of pure speculation.

Thou shouldst not become presumptuous through great connections and race; for in the end thy trust is on thine own deeds.

By phonemic transformation into visual terms, the alphabet became a universal, abstract, static container of meaningless sounds.

He chooses the most feared, most hated man in order to worship him as a god, feeling sure that he is alone in perceiving the god's secret virtues.

Some will ask, what about weak natures, must they not be protected? Yes, but to be able to do that, it will be necessary to realize that education of children is not synonymous with herdlike drilling and training. If education should really mean anything at all, it must insist upon the free growth and development of the innate forces and tendencies of the child. In this way alone can we hope for the free individual and eventually also for a free community, which shall make interference and coercion of human growth impossible.

Nobody really thinks who does not abstract from that which is given, who does not relate the facts to the factors which have made them, who does not - in his mind - undo the facts. Abstractness is the very life of thought, the token of its authenticity.

If the only significant history of human thought were to be written, it would have to be the history of its successive regrets and its impotences.

The chief requirement of the good life... is to live without any image of oneself.

One can only become a philosopher, but not be one. As one believes he is a philosopher, he stops being one.

We all want progress. But progress means getting nearer to the place where you want to be. And if you have taken a wrong turning, then to go forward does not get you any nearer. If you are on the wrong road, progress means doing an about-turn and walking back to the right road; in that case the man who turns back soonest is the most progressive man.

So-called professional mathematicians have, in their reliance on the relative incapacity of the rest of mankind, acquired for themselves a reputation for profundity very similar to the reputation for sanctity possessed by theologians.

We should, out of decency, choose for ourselves the moment to disappear.

A rolling stone gathers no moss.

Is it for this purpose that we are strong-that we may have light burdens to bear?
