Every true thinker for himself is so far like a monarch; he is absolute, and recognises nobody above him. His judgments, like the decrees of a monarch, spring from his own sovereign power and proceed directly from himself. He takes as little notice of authority as a monarch does of a command; nothing is valid unless he has himself authorised it. On the other hand, those of vulgar minds, who are swayed by all kinds of current opinions, authorities, and prejudices, are like the people which in silence obey the law and commands.

The real significance of the Russell paradox, from the standpoint of the modal-logic picture, is this: it shows that no concrete structure can be a standard model for the naive conception of the totality of all sets; for any concrete structure has a possible extension that contains more 'sets'. (If we identify sets with the points that represent them in the various possible concrete structures, we might say: it is not possible for all possible sets to exist in any one world!) Yet set theory does not become impossible. Rather, set theory becomes the study of what must hold in, e.g. any standard model for Zermelo set theory.

Capacity for the nobler feelings is in most natures a very tender plant, easily killed, not only by hostile influences, but by the mere want of sustenance; and in the majority of young persons it speedily dies away if the occupations to which their position in life has devoted them, and the society into which it has thrown them, are not favourable to keeping that higher capacity in existence.

We must choose for others as we have reason to believe they would choose for themselves if they were at the age of reason and deciding rationally.

Males learn to lie as a way of obtaining power, and females not only do the same but they also lie to pretend powerlessness.

The fact that the general incidence of leukemia has doubled in the last two decades may be due, partly, to the increasing use of x-rays for numerous purposes. The incidence of leukemia in doctors, who are likely to be so exposed, is twice that of the general public. In radiologists the incidence is ten times greater.

A man who for a long time has gone around hiding a secret becomes mentally deranged. At this point one would imagine that his secret would have to come out, but despite his derangement his soul still sticks to its hideout, and those around him become even more convinced that the false story he told to deceive them is the truth. He is healed of his insanity, knows everything that has gone on, and thereby perceives that nothing has been betrayed. Was this gratifying to him or not; he might wish to have disposed of his secret in his madness; it seems as if there were a fate which forced him to remain in his secret and would not let him go away from it. Or was it for the best, was there a guardian spirit who helped him keep his secret.

Marriage is encouraged in China, not by the profitableness of children, but by the liberty of destroying them.

What is our task in the question of peace? It does not consist merely in vigorously demonstrating at all times the love of peace of the Social Democrats; but first and foremost our task is to make clear to the masses of people the nature of militarism and sharply and clearly to bring out the differences in principle between the standpoint of the Social Democrats and that of the bourgeois peace enthusiasts.

Till women are more rationally educated, the progress in human virtue and improvement in knowledge must receive continual checks.

The great thing, then, in all education, is to make our nervous system our ally instead of our enemy.

And I will tell you something else: there is no birth of all mortal things, nor any end in wretched death, but only a mixing and dissolution of mixtures; 'birth' is so called on the part of mankind.

A Dialogue between two Infants in the womb concerning the state of this world, might handsomely illustrate our ignorance of the next, whereof methinks we yet discourse in Plato's Den, and are but Embryon Philosophers.

There are people in the world who desperately want not to have to believe in Darwinism.

Philosophy ... must not bargain away anything of the emphatic concept of truth.

The aged are cared for until death; adults are employed in jobs that make full use of their abilities; and children are nourished, educated, and fostered;...orphans... the disabled and the diseased are all well taken care of....

Law is the continuous manifestation of God's presence - not reason for believing him absent. Great confusion arises from our using the same word law in two totally distinct senses ... as the cause and the effect. It is said that to "explain away" everything by law is to enable us to do without God. But law is no explanation of anything; law is simply a generalization, a category of facts. Law is neither a cause, nor a reason, nor a power, nor a coercive force. It is nothing but a general formula, a statistical table. Law brings us continually back to God instead of carrying us away from him.

Never stay up on the barren heights of cleverness, but come down into the green valleys of silliness.

Don't you feel the same way? When I cannot see myself, even though I touch myself, I wonder if I really exist.

Days of absence,

sad and dreary, 

Clothed in sorrow's dark array,

Days of absence, I am weary: She I love is far away.

Whatever may happen to thee, it was prepared for thee from all eternity; and the implication of causes was from eternity spinning the thread of thy being, and of that which is incident to it. Alternate Translation: Whatever may befall you, it was preordained for you from everlasting.

Why don't I commit suicide? Because I am as sick of death as I am of life.

O reader, to what shifts is poor Society reduced, struggling to give still some account of herself, in epochs when Cash Payment has become the sole nexus of man to men!

I thought that the only action a man could perform without shame was to take his life; that he had no right to diminish himself in the succession of days and the inertic of misery. No elect, I kept telling myself, but those who committed suicide.

A man's thinking goes on within his consciousness in a seclusion in comparison with which any physical seclusion is an exhibition to public view.

Like computer viruses, successful mind viruses will tend to be hard for their victims to detect. If you are the victim of one, the chances are that you won't know it, and may even vigorously deny it. Accepting that a virus might be difficult to detect in your own mind, what tell-tale signs might you look out for? I shall answer by imaging how a medical textbook might describe the typical symptoms of a sufferer (arbitrarily assumed to be male).

The peoples' revolution .... will arrange its revolutionary organisation from the bottom up and from the periphery to the centre, in keeping with the principle of liberty.

The difference between a pessimistic and an optimistic mind is of such controlling importance in regard to every intellectual function, and especially for the conduct of life, that it is out of the question to admit that both are normal, and the great majority of mankind are naturally optimistic.

A man, in so far as he is an individual, may be very sharply detached from others, a sort of spiritual crustacean, and yet be very poor in differentiating content. And further, it is true on the other hand that the more personality a man has and the greater his interior riches and the more he is a society within himself, the less brusquely he is divided from his fellows.

There is only one cure for the evils which newly acquired freedom produces, and that cure is freedom.

Antisthenes ... said once to a youth from Pontus who was on the point of coming to him to be his pupil, and was asking him what things he wanted, "You want a new book, and a new pen, and a new tablet;"

He who has injured thee was either stronger or weaker than thee. If weaker, spare him; if stronger, spare thyself.

There always comes a time in history when the person who dares to say that 2+2=4 is punished by death. And the issue is not what reward or what punishment will be the outcome of that reasoning. The issue is simply whether or not 2+2=4.

As for me, I am mean: that means that I need the suffering of others to exist. A flame. A flame in their hearts. When I am all alone, I am extinguished.

According to the technical language of old writers, a thing and its qualities are described as subject and attributes; and thus a man's faculties and acts are attributes of which he is the subject. The mind is the subject in which ideas inhere. Moreover, the man's faculties and acts are employed upon external objects; and from objects all his sensations arise. Hence the part of a man's knowledge which belongs to his own mind, is subjective: that which flows in upon him from the world external to him, is objective.

You ask me why I do not write something... I think one's feelings waste themselves in words; they ought all to be distilled into actions and into actions which bring results.

What is food to one, is to others bitter poison.

Wherever you encounter truth, look upon it as Christianity.

The covetous man is ever in want.

But by far the greatest obstacle to the progress of science and to the undertaking of new tasks and provinces therein is found in this - that men despair and think things impossible.

And what is it in us that is mellowed by civilization? All it does, I'd say, is to develop in man a capacity to feel a greater variety of sensations. And nothing, absolutely nothing else. And through this development, man will yet learn how to enjoy bloodshed. Why, it has already happened....Civilization has made man, if not always more bloodthirsty, at least more viciously, more horribly bloodthirsty.

All who are not lunatics are agreed about certain things. That it is better to be alive than dead, better to be adequately fed than starved, better to be free than a slave. Many people desire those things only for themselves and their friends; they are quite content that their enemies should suffer. These people can only be refuted by science: Humankind has become so much one family that we cannot ensure our own prosperity except by ensuring that of everyone else. If you wish to be happy yourself, you must resign yourself to seeing others also happy.

Blessed is the lion which becomes man when consumed by man; and cursed is the man whom the lion consumes, and the lion becomes man. (7) This saying has been interpreted by some as referring to such anger as consumes a man…(rather than is consumed by him, through his reason and love), 'til that man is the lion of Anger. Other more mystical interpretations might also be found or devised that have merit.

That is the best government which desires to make the people happy, and knows how to make them happy.

Every technology contrived and "outered" by man has the power to numb human awareness during the period of its first interiorization.

The more ideas have become automatic, instrumentalized, the less does anybody see in them thoughts with a meaning of their own. They are considered things, machines. Language has been reduced to just another tool in the gigantic apparatus of production in modern society.

There are many things of which a wise man might wish to be ignorant.
