Judge not, that you be not judged. For with what judgment you judge, you will be judged; and with the measure you use, it will be measured back to you. And why do you look at the speck in your brother's eye, but do not consider the plank in your own eye? Or how can you say to your brother, 'Let me remove the speck from your eye'; and look, a plank is in your own eye? Hypocrite! First remove the plank from your own eye, and then you will see clearly to remove the speck from your brother's eye. 

The Plan of the System, may aim at a Natural or an Artificial System. But no classes can be absolutely artificial, for if they were, no assertions could be made concerning them.

The Calculus required continuity, and continuity was supposed to require the infinitely little; but nobody could discover what the infinitely little might be.

My convictions, positive and negative, on all the matters of which you speak, are of long and slow growth and are firmly rooted. But the great blow which fell on me seemed to stir them to their foundation, and had I lived a couple of centuries earlier I could have fancied a devil scoffing at me and them - and asking me what profit it was to have stripped myself of the hopes and consolations of the mass of mankind? To which my only reply was and is - Oh devil! Truth is better than much profit. I have searched over the grounds of my belief, and if wife and child and name and fame were all to be lost to me one after the other as the penalty, still I will not lie.

Choose a wife who is of character, because that one is good who in the end is more respected.

A religious creed differs from a scientific theory in claiming to embody eternal and absolutely certain truth, whereas science is always tentative, expecting that modification in its present theories will sooner or later be found necessary, and aware that its method is one which is logically incapable of arriving at a complete and final demonstration.

Human knowledge and human power meet in one; for where the cause is not known the effect cannot be produced. Nature to be commanded must be obeyed; and that which in contemplation is as the cause is in operation as the rule.

We may treat of the Soul as in the body whether it be set above it or actually within it since the association of the two constitutes the one thing called the living organism, the Animate. Now from this relation, from the Soul using the body as an instrument, it does not follow that the Soul must share the body's experiences: a man does not himself feel all the experiences of the tools with which he is working.

Regardless of the present trend toward the strong-armed man, the totalitarian states, or the dictatorship from the left, my ideas have remained unshaken. In fact, they have been strengthened by my personal experience and the world events through the years. I see no reason to change, as I do not believe that the tendency of dictatorship can ever successfully solve our social problems. As in the past, so I do now insist that freedom is the soul of progress and essential to every phase of life. I consider this as near a law of social evolution as anything we can postulate. My faith is in the individual and in the capacity of free individuals for united endeavor.

Though I certainly deserve no ill treatment from mortals, yet if the insults and repulses I receive were attended with any advantage to them, I would content myself with lamenting in silence my own unmerited indignities and man's injustice.

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.

Value has its own logic. In the constitutional state that is most clearly recognizable in the enactment of its constitution.

To spare the guilty is to injure the innocent.

The commodities of Europe were almost all new to America, and many of those of America were new to Europe. A new set of exchanges, therefore, began..and which should naturally have proved as advantageous to the new, as it certainly did to the old continent. The savage injustice of the Europeans rendered an event, which ought to have been beneficial to all, ruinous and destructive to several of those unfortunate countries.

All the world's not a stage.

Jung fiercely resented the implication that he was a hypocritical, self-seeking Judas, a 'rat'. Yet there was just enough truth in it to strike home. He was undoubtedly a man who liked his own way, no matter what the cost to others.

So people should abstain from other animals just as they should from the human.

What I have given in the second book on the nature and properties of curved lines, and the method of examining them, is, it seems to me, as far beyond the treatment in the ordinary geometry, as the rhetoric of Cicero is beyond the a, b, c of children.

From each as they choose, to each as they are chosen.

Until writing was invented, man lived in acoustic space: boundless, directionless, horizonless, in the dark of the mind, in the world of emotion, by primordial intuition, terror. Speech is a social chart of this bog.

Why is it after a century of socialist disasters, and an intellectual legacy that has been time and again exploded, the left-wing position remains, as it were, the default position to which thinking people gravitate when called upon for a comprehensive philosophy? Why are "right-wingers" marginalised in the educational system, denounced in the media and regarded by our political class as untouchable, fit only to clean up after the orgies of luxurious nonsense indulged in by their moral superiors?

The problem... Democracy is founded by a politeia, a constitution, where the demos, the people, exercise power, and... everyone is equal in front of the law. Such a constitution... is condemned to give equal place to all forms of parrhesia, even the worst. Because parrhesia is given even to the worst citizens, the overwhelming influence of bad, immoral, or ignorant speakers may lead... into tyranny, or... otherwise endanger the city. Hence parrhesia may be dangerous for democracy itself.

The mosaic form of the TV image demands participation and involvement in depth, of the whole being, as does the sense of touch.

True philosophy must start from the most immediate and comprehensive fact of consciousness: "I am life that wants to live, in the midst of life that wants to live."

A man's body and the needs of his body are now everywhere treated with a tender indulgence. Is the thinking mind then, to be the only thing that is never to obtain the slightest measure of consideration or protection, to say nothing of respect?

The strangest, most generous, and proudest of all virtues is true courage.

We are delighted to find a person who values us as we value ourselves, and distinguishes us from the rest of mankind, with an attention not unlike that with which we distinguish ourselves.

When the soul has descended into generation (from its first divine condition) she partakes of evil, and is carried a great way into a state the opposite of her first purity and integrity, to be entirely merged in which, is nothing more than to fall into a dark mire. ...The soul dies as much as it is possible for the soul to die: and the death to her is, while baptized or immersed in the present body, to descend into matter, and be wholly subjected by it; and after departing thence to lie there til it shall arise and turn its face away from the abhorrent filth. This is what is meant by falling asleep in Hades, of those who have come there.

Executions, far from being useful examples to the survivors, have, I am persuaded, a quite contrary effect, by hardening the heart they ought to terrify. Besides, the fear of an ignominious death, I believe, never deterred anyone from the commission of a crime, because in committing it the mind is roused to activity about present circumstances.

To free a man from error is to give, not to take away. Knowledge that a thing is false is a truth. Error always does harm; sooner or later it will bring mischief to the man who harbors it. Then give up deceiving people; confess ignorance of what you don't know, and leave everyone to form his own articles of faith for himself. Perhaps they won't turn out so bad, especially as they'll rub one another's corners down, and mutually rectify mistakes. The existence of many views will at any rate lay a foundation of tolerance. Those who possess knowledge and capacity may betake themselves to the study of philosophy, or even in their own persons carry the history of philosophy a step further.

It goes without saying that any persons may attempt to unite kindred spirits, but, whatever their hopes and longings, none have the right to impose their vision of unity upon the rest.

That body is heavier than another which, in an equal bulk, moves downward quicker.

The ultimate result of shielding men from the effects of folly, is to fill the world with fools.

Everywhere in life, the true question is not what we gain, but what we do.

The highest manifestation of life consists in this: that a being governs its own actions. A being that is always subject to the direction of another is somewhat of a dead thing. Variant translation: Now slavery has a certain likeness to death, hence it is also called civil death. For life is most evident in a thing's moving itself, while what can only be moved by another, seems to be as if dead. But it is manifest that a slave is not moved by himself, but only at his master's command.

What, then, of human activities? Is humankind itself hastening its own end? Man has, for instance, been burning carbon-containing fuel — wood, coal, oil, gas — at a steadily accelerating rate. All these fuels form carbon dioxide. Some is absorbed by plants and the oceans but not as fast as it is produced. This means the carbon dioxide content of the air is going up — slightly but nevertheless up. Carbon dioxide retains heat, and even a small rise means a warming of the Earth's atmosphere. This may result in the melting of the polar ice caps with unusual speed, flooding the world before we have learned climate control. In reverse, our industrial civilization is making our atmosphere dustier so that it reflects more sunlight away and cools the Earth slightly — thus making possible a glacial advance in a few centuries, also before we have learned climate control.

The painter is turning his eyes towards us only in so far as we happen to occupy the same position as his subject. We, the spectators, are an additional factor. Though greeted by that gaze, we are also dismissed by it, replaced by that which was always there before we were: the model itself. But, inversely, the painter's gaze, addressed to the void confronting him outside the picture, accepts as many models as there are spectators; in this precise but neutral place, the observer and the observed take part in a ceaseless exchange.

For Christ is Joy and Sweetness to a broken heart. Christ is a Lover of poor sinners, and such a Lover that He gave Himself for us. Now if this is true, and it is true, then are we never justified by our own righteousness.

The Prodigal Son at least walked home on his own feet. But who can duly adore that Love which will open the high gates to a prodigal who is brought in kicking, struggling, resentful, and darting his eyes in every direction for a chance of escape?

In a well worn metaphor, a parallel is drawn between the life of man and the metamorphosis of the caterpillar into the butterfly; but the comparison may be more just as well as more novel, if for its former term we take the mental progress of the race. History shows that the human mind, fed by constant accessions of knowledge, periodically grows too large for its theoretical coverings, and bursts them asunder to appear in new habiliments, as the feeding and growing grub, at intervals, casts its too narrow skin and assumes another, itself but temporary. Truly the imago state of Man seems to be terribly distant, but every moult is a step gained, and of such there have been many.

Frantic administration of panaceas to the world is certainly discouraged by the reflection that "this present" might be "the world's last night"; sober work for the future, within the limits of ordinary morality and prudence, is not.

Moral activity? There is scarcely such a thing possible! Everything is sketchy. The world does nothing but sketch.

We should have with each person the relationship of one conception of the universe to another conception of the universe, and not to a part of the universe.

In that very hour he became overjoyed in the holy spirit and said: “I publicly praise you, Father, Lord of heaven and earth, because you have carefully hidden these things from wise and intellectual ones and have revealed them to young children. Yes, O Father, because this is the way you approved.

And virtue they will curse, speaking harsh words.

Even from their infancy we frame them to the sports of love: their instruction, behavior, attire, grace, learning and all their words azimuth only at love, respects only affection. Their nurses and their keepers imprint no other thing in them.

Can anyone be proved innocent, if it be enough to have accused him?

In formal logic, a contradiction is the signal of a defeat; but in the evolution of real knowledge it marks the first step in progress towards a victory.
