Look now, this is the starting point of philosophy: the recognition that different people have conflicting opinions, the rejection of mere opinion so that it comes to be viewed with mistrust, an investigation of opinion to determine whether it is rightly held, and the discovery of a standard of judgement, comparable to the balance that we have devised for the determining of weights, or the carpenter's rule for determining whether things are straight or crooked.

Query: How to contrive not to waste one's time? Answer: By being fully aware of it all the while. Ways in which this can be done: By spending one's days on an uneasy chair in a dentist's waiting room; by remaining on one's balcony all a Sunday afternoon; by travelling by the longest and least-convenient train routes, and of course standing all the way; by queueing at the box-office of theatres and then not booking a seat.

[L]ike Coleridge, he might plead as a set-off that he had been to many persons, through his conversation, a source not only of much instruction but of great elevation of character. On me his influence was most salutary. It was moral in the best sense. He took a sincere and kind interest in me, far beyond what could have been expected towards a mere youth from a man of his age, standing, and what seemed austerity of character. There was in his conversation and demeanour a tone of high-mindedness which did not show itself so much, if the quality existed as much, in any of the other persons with whom at that time I associated. My intercourse with him was the more beneficial, owing to his being of a different mental type from all other intellectual men whom I frequented...

If it had pleased them [the legislators] to order that this wealth, after having been possessed by fathers during their life, should return to the republic after their death, you would have no reason to complain of it.

Hear, and understand: Not that which goeth into the mouth defileth a man; but that which cometh out of the mouth, this defileth a man. 15:10-11 (KJV)

Our responsibility is much greater than we might have supposed, because it involves all mankind.

I, for my part, do not conceive an act as having causes, and I consider myself satisfied when I have found in it not its 'factors' but the general themes which it organizes: for our decisions gather into new syntheses and on new occasions the leitmotif that governs our life

Since men in their endeavors behave, on the whole, not just instinctively, like the brutes, nor yet like rational citizens of the world according to some agreed-on plan, no history of man conceived according to a plan seems to be possible, as it might be possible to have such a history of bees or beavers. One cannot suppress a certain indignation when one sees men's actions on the great world-stage and finds, beside the wisdom that appears here and there among individuals, everything in the large woven together from folly, childish vanity, even from childish malice and destructiveness. In the end, one does not know what to think of the human race, so conceited in its gifts.

For a desperate disease a desperate cure.

So the Church too, like Mary, enjoys perpetual virginity and uncorrupted fecundity.

But though empires, like all the other works of men, have all hitherto proved mortal, yet every empire aims at immortality.

It is enough to ask somebody for his weapons without saying 'I want to kill you with them', because when you have his weapons in hand, you can satisfy your desire.

One must have a good memory to be able to keep the promises one makes.

The more man meditates upon good thoughts, the better will be his world and the world at large.

These preachers of beauty, which light the world with their admonishing smile.

A Christian has no need of any law in order to be saved, since through faith we are free from every law. Thus all the acts of a Christian are done spontaneously, out of a sense of pure liberty. As Christians we do not seek our own advantage or salvation because we are already fully satisfied and saved by God's grace through faith. Now our only motive is to do that which is pleasing to God.

The pervasiveness of social dilemmas has repeatedly been recognized in the great books of political philosophy. Hobbes described such a setting as a "war of all against all." Rousseau used a stag hunt to illustrate the problem of a group needing to all work together to hunt a large animal but facing the temptation to break up into separate groups when small animals appeared on the scene that were easy to catch. A small group could catch a rabbit, but ruined the chance for the group to obtain a large animal. Elinor Ostrom, Understanding Institutional Diversity (2005), Ch. 2 : Zooming In and Linking Action Situations

Don't discuss yourself, for you are bound to lose; if you belittle yourself, you are believed; if you praise yourself, you are disbelieved.

Plato... introduces two infinities, because both in increase and diminution there appears to be transcendency, and a progression to infinity. Though... he did not use them: for neither is there infinity in numbers by diminution or division; since unity is a minimum: nor by increase; for he extends number as far as to the decad.

He could almost wish he were superstitious. He could then console himself with the thought that the casual meaningless meeting had really been directed by a knowing and purposeful Fate.

Lift up your eyes and look at the cloud and the light within it and the stars surrounding it. The star that leads the way is your star. Jesus to Judas, Judas. See "Jesus Laughed" and "Judas Saves: Why the lost gospel makes sense".

The first thing to realize, if you wish to become a philosopher, is that most people go through life with a whole world of beliefs that have no sort of rational justification, and that one man's world of beliefs is apt to be incompatible with another man's, so that they cannot both be right. People's opinions are mainly designed to make them feel comfortable; truth, for most people is a secondary consideration.

What! the inventors of ancient civilisations, the first makers of tools and tape lines, the first builders of vehicles, ships, and houses, the first observers of the laws of the heavens and the multiplication tables is it contended that they were entirely different from the inventors and observers of our own time, and superior to them? And that the first slow steps forward were of a value which has not been equalled by the discoveries we have made with all our travels and circumnavigations of the earth?

In every stock-jobbing swindle everyone knows that some time or other the crash must come, but every one hopes that it may fall on the head of his neighbour, after he himself has caught the shower of gold and placed it in safety.

Earth is a ball that is over 12,000 kilometres in diameter, and if it were modelled into an object the size of a billiard ball, with all its surface unevenness reproduced exactly to scale, the model would be smoother than an ordinary billiard ball and the ocean would be an all but unnoticeable mist of dampness over 70 percent of its surface.

In the part of this universe that we know there is great injustice, and often the good suffer, and often the wicked prosper, and one hardly knows which of those is the more annoying.

The trade of governing has always been monopolized by the most ignorant and the most rascally individuals of mankind.

I work quite diligently and wish that I were better and smarter. And these both are one and the same.

M. Desargues puts me under obligations on account of the pains that it has pleased him to have in me, in that he shows that he is sorry that I do not wish to study more in geometry, but I have resolved to quit only abstract geometry, that is to say, the consideration of questions which serve only to exercise the mind, and this, in order to study another kind of geometry, which has for its object the explanation of the phenomena of nature... You know that all my physics is nothing else than geometry.

Some things are in our control and others not. Things in our control are opinion, pursuit, desire, aversion, and, in a word, whatever are our own actions. Things not in our control are body, property, reputation, command, and, in one word, whatever are not our own actions.

Maybe the target nowadays is not to discover what we are but to refuse what we are.

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.

My aim is not to provide excuses for black behavior or to absolve blacks of personal responsibility. But when the new black conservatives accent black behavior and responsibility in such a way that the cultural realities of black people are ignored, they are playing a deceptive and dangerous intellectual game with the lives and fortunes of disadvantaged people. We indeed must criticize and condemn immoral acts of black people, but we must do so cognizant of the circumstances into which people are born and under which they live. By overlooking these circumstances, the new black conservatives fall into the trap of blaming black poor people for their predicament. It is imperative to steer a course between the Scylla of environmental determinism and the Charybdis of a blaming-the-victims perspective.

The problem is not to discover in oneself the truth of one's sex, but, rather, to use one's sexuality henceforth to arrive at a multiplicity of relationships. And, no doubt, homosexuality is not a form of desire but something desirable. Therefore, we have to work at becoming homosexuals.

All the thoughts of a turtle are turtle.

The tolls for the maintenance of a high road, cannot with any safety be made the property of private persons.

Persons of genius, it is true, are, and are always likely to be, a small minority; but in order to have them, it is necessary to preserve the soil in which they grow. Genius can only breathe freely in an atmosphere of freedom.

Complete ignorance with regard to certain matters is perhaps the best thing for children; but let them learn very early what it is impossible to conceal from them permanently. Either their curiosity must never be aroused, or it must be satisfied before the age when it becomes a source of danger. Your conduct towards your pupil in this respect depends greatly on his individual circumstances, the society in which he moves, the position in which he may find himself, etc. Nothing must be left to chance; and if you are not sure of keeping him in ignorance of the difference between the sexes till he is sixteen, take care you teach him before he is ten.

There must then be something that is better, and that must be God. When you see a stately and stupendous edifice, though you do not know who is the owner of it, you would yet conclude it was not built for rats. And this divine structure, that we behold of the celestial palace, have we not reason to believe that it is the residence of some possessor, who is much greater than we?

If the world were clear, art would not exist.

Things are pretty, graceful, rich, elegant, handsome, but, until they speak to the imagination, not yet beautiful.

The law will never make men free; it is men who have got to make the law free.

Analytical geometry was invented by Descartes and the first exposition of it was given in 1637: that exposition was both difficult and obscure, and to most of his contemporaries, to whom the method was new, it must have been incomprehensible. Wallis made the method intelligible to all mathematicians.

Morality is the beauty of Philosophy.

There are two types of poor people, those who are poor together and those who are poor alone. The first are the true poor, the others are rich people out of luck.

What peculiar privilege has this little agitation of the brain which we call thought, that we must thus make it the model of the whole universe? Our partiality in our own favour does indeed present it on all occasions; but sound philosophy ought carefully to guard against so natural an illusion.

My aim is: to teach you to pass from a piece of disguised nonsense to something that is patent nonsense.

There are hardly any truths upon which we always remain agreed, and still fewer objects of pleasure which we do not change every hour, I do not know whether there is a means of giving fixed rules for adapting discourse to the inconstancy of our caprices.

So that in the first place, I put for a general inclination of all mankind a perpetual and restless desire of Power after power, that ceaseth only in Death. And the cause of this is not always that a man hopes for a more intensive delight than he has already attained to, or that he cannot be content with a moderate power: but because he cannot assure the power and means to live well, which he hath present, without the acquisition of more.
