Body and soul: a horse harnessed beside an ox.

Every one excels in something in which another fails.

By an object, I mean anything that we can think, i.e. anything we can talk about.

To study and not think is a waste. To think and not study is dangerous. Learning without thought is labor lost; thought without learning is perilous.

A sovereign shows himself to be a tyrant if he disregards his honest advisors, or punishes them for what they have said.

I am a mariner of Odysseus with heart of fire but with mind ruthless and clear.

Resignation' is a keynote in Comte's writings, deriving directly from assent to invariable social laws. 'True resignation, that is, a disposition to endure necessary evils steadfastly and without any hope of compensation therefore, can result only from a profound feeling for the invariable laws that govern the variety of natural phenomena.

It is debasing to die the way one does; it is intolerable to be exposed to an end over which we have no control, an end which lies in wait for us, overthrows us, casts us into the unnameable.

I should prefer that Fortune keep me in her camp rather than in the lap of luxury. If I am tortured, but bear it bravely, all is well; if I die, but die bravely, it is also well.

As we shall see later, the most important factor in the training of good mental habits consists in acquiring the attitude of suspended conclusion, and in mastering the various methods of searching for new materials to corroborate or to refute the first suggestions that occur. To maintain the state of doubt and to carry on systematic and protracted inquiry ― these are the essentials of thinking.

May not we then confidently pronounce that man happy who realizes complete goodness in action, and is adequately furnished with external goods? Or should we add, that he must also be destined to go on living not for any casual period but throughout a complete lifetime in the same manner, and to die accordingly, because the future is hidden from us, and we conceive happiness as an end, something utterly and absolutely final and complete? If this is so, we shall pronounce those of the living who possess and are destined to go on possessing the good things we have specified to be supremely blessed, though on the human scale of bliss.

Elements of empirical language are manipulated in their rigidity, as if they were elements of a true and revealed language. The empirical usability of the sacred ceremonial words makes both the speaker and listener believe in their corporeal presence.

This right which you have, is not founded any more than his upon any quality or any merit in yourself which renders you worthy of it. Your soul and your body are, of themselves, indifferent to the state of boatman or that of duke; and there is no natural bond that attaches them to one condition rather than to another.

I am writing to you to tell you of my decision to return to your Government the Carl von Ossietzsky medal for peace. I do so reluctantly and after two years of private approaches on behalf of Heinz Brandt, whose continued imprisonment is a barrier to coexistence, relaxation of tension and understanding between East and West... I regret not to have heard from you on this subject. I hope that you will yet find it possible to release Brandt through an amnesty which would be a boon to the cause of peace and to your country.

With the abolition of otium and of the ego no aloof thinking is left. ... Without otium philosophical thought is impossible, cannot be conceived or understood.

As long as you live, keep learning how to live.

Poetry is the mysticism of mankind.

All religions are cruel, all founded on blood; for all rest principally on the idea of sacrifice - that is, on the perpetual immolation of humanity to the insatiable vengeance of divinity.

The new tinge to modern minds is a vehement and passionate interest in the relation of general principles to irreducible and stubborn facts. All the world over and at all times there have been practical men, absorbed in 'irreducible and stubborn facts'; all the world over and at all times there have been men of philosophic temperament, who have been absorbed in the weaving of general principles. It is this union of passionate interest in the detailed facts with equal devotion to abstract generalisation which forms the novelty of our present society.

Good nature is, of all moral qualities, the one that the world needs most, and good nature is the result of ease and security, not of a life of arduous struggle. Modern methods of production have given us the possibility of ease and security for all; we have chosen, instead, to have overwork for some and starvation for the others. Hitherto we have continued to be as energetic as we were before there were machines; in this we have been foolish, but there is no reason to go on being foolish for ever.

There are 80,000 prostitutes in London alone and what are they, if not bloody sacrifices on the altar of monogamy?

Where the preamble declares, that coercion is a departure from the plan of the holy author of our religion, an amendment was proposed by inserting "Jesus Christ," so that it would read "A departure from the plan of Jesus Christ, the holy author of our religion;" the insertion was rejected by the great majority, in proof that they meant to comprehend, within the mantle of its protection, the Jew and the Gentile, the Christian and Mohammedan, the Hindoo and Infidel of every denomination.

The organism does not have a point of view: the person or creature does.

What Heaven has conferred is called The Nature; an accordance with this nature is called The Path of duty; the regulation of this path is called Instruction. The path may not be left for an instant. If it could be left, it would not be the path. On this account, the superior man does not wait till he sees things, to be cautious, nor till he hears things, to be apprehensive.

It is of this sort of divine service I used the expression that, in comparison with the Christianity of the New Testament, it is playing Christianity. The expression is essentially true and characterizes the thing perfectly. For what does it mean to play, when one reflects how the word must be understood in this connection? It means to imitate, to counterfeit, a danger when there is no danger, and to do it in such a way that the more art is applied to it, the more delusive the pretense is that the danger is present.

The methods of coping with crime have no doubt undergone several changes, but mainly in a theoretic sense. In practice, society has retained the primitive motive in dealing with the offender; that is, revenge.

Is it not a noble farce, wherein kings, republics, and emperors have for so many ages played their parts, and to which the whole vast universe serves for a theatre?

The welfare of the people in particular has always been the alibi of tyrants, and it provides the further advantage of giving the servants of tyranny a good conscience. It would be easy, however, to destroy that good conscience by shouting to them: if you want the happiness of the people, let them speak out and tell what kind of happiness they want and what kind they don't want! But, in truth, the very ones who make use of such alibis know they are lies; they leave to their intellectuals on duty the chore of believing in them and of proving that religion, patriotism, and justice need for their survival the sacrifice of freedom.

The next thing is by gentle degrees to accustom children to those things they are too much afraid of. But here great caution is to be used, that you do not make too much haste, nor attempt this cure too early, for fear lest you increase the mischief instead of remedying it.

No man must encroach upon my province nor I upon his. He may advise me, moderately and without perniciousness, but he must not expect to dictate to me. He may censure me freely and without reserve but he should remember that I am to act by my deliberation and not his. He may exercise a republican boldness in judging, but he must not be peremptory and imperious in prescribing. Force may never be resorted to but, in the most extraordinary and imperious emergency.

Men may one day feel that they are partakers of a common nature, and that true freedom and perfect equity, like food and air, are pregnant with benefit to every constitution.

Quiet minds cannot be perplexed or frightened but go on in fortune or misfortune at their own private pace, like a clock during a thunderstorm.

Utopia is a meta-utopia: the environment in which Utopian experiments may be tried out; the environment in which people are free to do their own thing; the environment which must, to a great extent, be realized first if more particular Utopian visions are to be realized stably.

A critique is not a matter of saying that things are not right as they are. It is a matter of pointing out on what kinds of assumptions, what kinds of familiar, unchallenged, unconsidered modes of thought the practices that we accept rest.

Everything turns on pain; the rest is accessory, even nonexistent, for we remember only what hurts. Painful sensations being the only real ones, it is virtually useless to experience others.

The chief danger to philosophy is narrowness in the selection of evidence.

Live always in the best company when you read.

One reason why mathematics enjoys special esteem, above all other sciences, is that its laws are absolutely certain and indisputable, while those of other sciences are to some extent debatable and in constant danger of being overthrown by newly discovered facts.

The representation of the self-sufficiency of the I can certainly co-exist with a representation of the self-sufficiency of the thing, though the self-sufficiency of the I itself cannot co-exist with that of the thing. Only one of these two can come first, only one can be the starting point; only one can be independent. The one that comes second, just because it comes second, necessarily becomes dependent upon the one that comes first, with which it is supposed to be connected. Which of these two should come first?

Nor is anything empty: For what is empty is nothing. What is nothing cannot be.Nor does it move; for it has nowhere to betake itself to, but is full. For if there were aught empty, it would betake itself to the empty. But, since there is naught empty, it has nowhere to betake itself to.

He was a one-book man. Some men have only one book in them; others, a library.

What a judgment upon the living, if it is true, as has been maintained, that what dies has never existed!

This provides us with our first major clue to the solutions of the problem. Even if the left cannot see the world as full of potentiality, it can hold on to the moments of insight and refuse to let go of them. If I know that present difficulties will end in triumph, I am un-discourageable; I merely have to know it intellectually. And if I can 'know' that reality actually has a third dimension, I shall never fall into the mistake of complaining that there is nothing new under the sun and that life is futile.

We are either going to have a future where women lead the way to make peace with the Earth or we are not going to have a future at all.
