One man will say a thing of himself without comprehending its excellence, in which another will discern a marvelous series of conclusions, which makes us affirm that it is no longer the same expression, and that he is no more indebted for it to the one from whom he has learned it, than a beautiful tree belongs to the one who cast the seed, without thinking of it, or knowing it, into the fruitful soil which caused its growth by its own fertility.

The ancient Egyptians had a superstitious antipathy to the sea; a superstition nearly of the same kind prevails among the Indians; and the Chinese have never excelled in foreign commerce.

One recognizes one's course by discovering the paths that stray from it.

Choose rather to be strong in soul than in body.

And how does the God's existence emerge from the proof? Does it follow straightway, without any breach of continuity? Or have we not here an analogy to the behavior of the little Cartesian dolls? As soon as I let go of the doll it stands on its head. As soon as I let it go, I must therefore let it go. So also with the proof. As long as I keep my hold on the proof, i.e., continue to demonstrate, the existence does not come out, if for no other reason than that I am engaged in proving it; but when I let the proof go, the existence is there. But this act of letting go is surely also something; it is indeed a contribution of mine. Must not this also be taken into the account, this little moment, brief as it may be – it need not be long, for it is a leap. However brief this moment, if only an instantaneous now, this "now" must be included in the reckoning.

I have always thought the actions of men the best interpreters of their thoughts.

But it is clear there is a difference in the ends proposed: for in some cases they are activities, and in others results beyond the mere activities, and where there are certain ends beyond and beside the actions, the results are naturally superior to the activities. Now, as there are numerous kinds of actions and numerous arts and sciences, it follows that the ends are also various. Thus the end of the healing art is health, of ship-building ships, of strategy victory, of economy wealth.

The foundation of irreligious criticism is: Man makes religion, religion does not make man.

There is no art which one government sooner learns of another than that of draining money from the pockets of the people.

The rich man... is always sold to the institution which makes him rich.

We can pool information about experiences, but never the experiences themselves. From family to nation, every human group is a society of island universes.

Her absence is no more emphatic in those places than anywhere else. It's not local at all. I suppose if one were forbidden all salt one wouldn't notice it much more in any one food more than another. Eating in general would be different, every day, at every meal. It is like that. The act of living is different all through. Her absence is like the sky, spread over everything.

Be loyal and trustworthy. Do not befriend anyone who is lower than yourself in this regard. When making a mistake, do not be afraid to correct it.

Some of their faults people readily admit, but others not so readily.

The heavens are as deep as our aspirations are high.

To look for a single general theory of how to decide the right thing to do is like looking for a single theory of how to decide what to believe.

The work of each individual contributes to a totality and so becomes an undying part of the totality. That totality of human lives - past and present and to come - forms a tapestry that has been in existence now for many thousands of years and has been growing more elaborate and, on the whole, more beautiful in all that time. Even the Spacers are an offshoot of the tapestry and they, too, add to the elaborateness and beauty of the pattern. An individual life is one thread in the tapestry and what is one thread compared to the whole?

Maybe this world is another planet's Hell.

It is said in the Book of Poetry, "In silence is the offering presented, and the spirit approached to; there is not the slightest contention." Therefore the superior man does not use rewards, and the people are stimulated to virtue. He does not show anger, and the people are awed more than by hatchets and battle-axes.

How vain it is to sit down to write when you have not stood up to live.

Night is falling: at dusk, you must have good eyesight to be able to tell the Good Lord from the Devil.

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.

It is easier to discover a deficiency in individuals, in states, and in providence, than to see their real import or value.

Once we have tasted the sweetness of what is spiritual, the pleasures of the world will have no attraction for us. If we disregard the shadows of things, then we will penetrate their inner substance.

Nothing is in the intellect that was not first in the senses.

The core of ethics runs deep in our species and is common to human beings everywhere. It survives the most appalling hardships and the most ruthless attempts to deprive human beings of their humanity. Nevertheless, some people resist the idea that his core has a biological basis which we have inherited from our pre-human ancestors.

He [Jesus] not only forbids actual uncleanness, but all irregular desires, upon pain of hell-fire; causeless divorces; swearing in conversation, as well as forswearing in judgment; revenge; retaliation; ostentation of charity, of devotion, and of fasting; repetitions in prayer, covetousness, worldly care, censoriousness: and on the other side commands loving our enemies, doing good to those that hate us, blessing those that curse us, praying for those that despitefully use us; patience and meekness under injuries, forgiveness, liberality, compassion: and closes all; his particular injunctions, with this general golden rule, Matt. VII. 12, "All things whatsoever ye would that men should do to you, do you even so to them, for this is the law and the prophets." And to show how much He is in earnest, and expects obedience to these laws, He tells them, Luke VI. 35, That if they obey, " great shall be their reward".

Every time you make a choice you are turning the central part of you, the part of you that chooses, into something a little different from what it was before. And taking your life as a whole, with all your innumerable choices, all your life long you are slowly turning this central thing either into a heavenly creature or into a hellish creature: either into a creature that is in harmony with God, and with other creatures, and with itself, or else into one that is in a state of war and hatred with God, and with its fellow-creatures, and with itself. To be the one kind of creature is heaven: that is, it is joy and peace and knowledge and power. To be the other means madness, horror, idiocy, rage, impotence, and eternal loneliness. Each of us at each moment is progressing to the one state or the other.

It seems to be almost an invariable rule that as real power declines, the symbols of power multiply and intensify in compensation.

It is sometimes said, common sense is very rare.

[T]he ancient philosophers... all of them assert that the elements, and those things which are called by them principles, are contraries, though they establish them without reason, as if they were compelled to assert this by truth itself. They differ, however... that some of them assume prior, and others posterior principles; and some of them things more known according to reason, but others such as are more known according to sense: for some establish the hot and the cold, others the moist and the dry, others the odd and the even, and others strife and friendship, as the causes of generation. ...in a certain respect they assert the same things, and speak differently from each other. They assert different things... but the same things, so far as they speak analogously. For they assume principles from the same co-ordination; since, of contraries, some contain, and others are contained.

There is nothing in any object, consider'd in itself, which can afford us a reason for drawing a conclusion beyond it; [...] even after the observation of the frequent or constant conjunction of objects, we have no reason to draw any inference concerning any object beyond those of which we have had experience.

The history of all hitherto existing society is the history of class struggles.

If God did not exist, it would be necessary to invent him.

O my Father, if this cup may not pass away from me, except I drink it, thy will be done. 26:42 (KJV)

I hope, said the third, that your wanderings in lonely places do not mean that you have any of the romantic virus still in your blood. His name was Mr. Humanist.

The significance of that 'absolute commandment', know thyself - whether we look at it in itself or under the historical circumstances of its first utterance - is not to promote mere self-knowledge in respect of the particular capacities, character, propensities, and foibles of the single self. The knowledge it commands means that of man's genuine reality - of what is essentially and ultimately true and real - of spirit as the true and essential being.

People seem not to see that their opinion of the world is also a confession of character.

Truth springs from argument amongst friends.

When I obey a rule, I do not choose. I obey the rule blindly.

Nature made women mature early and had them demand gentle and polite treatment from men, so that they would find themselves imperceptibly fettered by a child due to their own magnanimity; and they would find themselves brought, if not quite to morality itself, then at least to that which cloaks it, moral behavior, which is the preparation and introduction to morality.

There can be no brotherhood when some nations indulge in previously unheard of luxuries, while others struggle to stave off famine.

To each according to his threat advantage does not count as a principle of justice.

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.

It is a mistake to classify the passions as lawful and unlawful, so as to yield to the one and refuse the other. All alike are good if we are their masters; all alike are bad if we abandon ourselves to them. Nature forbids us to extend our relations beyond the limits of our strength; reason forbids us to want what we cannot get, conscience forbids us, not to be tempted, but to yield to temptation. To feel or not to feel a passion is beyond our control, but we can control ourselves. Every sentiment under our own control is lawful; those which control us are criminal. A man is not guilty if he loves his neighbour's wife, provided he keeps this unhappy passion under the control of the law of duty; he is guilty if he loves his own wife so greatly as to sacrifice everything to that love.

Every man takes the limits of his own field of vision for the limits of the world.

Have patience awhile; slanders are not long-lived. Truth is the child of time; erelong she shall appear to vindicate thee.

Age imprints more wrinkles in the mind than it does on the face.
