No man can have society upon his own terms. If he seeks it, he must serve it too.

Since my logic aims to teach and instruct the understanding, not that it may with the slender tendrils of the mind snatch at and lay hold of abstract notions (as the common logic does), but that it may in very truth dissect nature, and discover the virtues and actions of bodies, with their laws as determined in matter; so that this science flows not merely from the nature of the mind, but also from the nature of things.

Nowadays three witty turns of phrase and a lie make a writer.

Wherever we turn we find that the real obstacles to peace are human will and feeling, human convictions, prejudices, opinions. If we want to get rid of war we must get rid first of all of its psychological causes. Only when this has been done will the rulers of the nations even desire to get rid of the economic and political causes.

I fear that the chief Reason why Chymists have written so obscurely of their three Principles, may be, That not having Clear and Distinct Notions of them themselves, they cannot write otherwise then Confusedly of what they but Confusedly Apprehend. Not to say that divers of them, being Conscious to the Invalidity of their Doctrine, might well enough discerne that they could scarce keep themselves from being confuted, but by keeping themselves from being clearly understood.

Irony is a qualification of subjectivity.

One of the commonplaces of modern historiography is the polemical exaltation of the civilization of the Renaissance over and against medieval civilization. This is not just the expression of a typical misunderstanding, since this mentality is the effect of one among the innumerable deceptions purposely spread in modern culture by the leaders of global subversion. The truth is that after the collapse of the ancient world, if there ever was a civilization that deserves the name of Renaissance, this was the civilization of the Middle Ages. In its objectivity, its virile spirit, its hierarchical structure, its proud antihumanistic simplicity so often permeated by the sense of the sacred, the Middle Ages represented a return to the origins.

The distinction between the world of commerce and that of "culture" quickly became the distinction between infrastructure and superstructure, with the former clearly determining the latter.

A screen bans reality.

How many women thus waste life away the prey of discontent, who might have practised as physicians, regulated a farm, managed a shop, and stood erect, supported by their own industry, instead of hanging their heads surcharged with the dew of sensibility, that consumes the beauty to which it at first gave lustre.

Those least responsible for climate change are worst affected by it.

The various philosophies of life presented themselves as a conquest of materialism, or in any case, they readily claimed it. That does not change anything: their valuations, revaluations, and explanations of disvalue have been emptied into the over-all secularization stream, where they have only hastened the tendency to unlearn, which is a neutralizing process, after all.

The distinction between private and public undermines the unity of spiritual strength, draining the public of the transcendent energies while trivializing them because the merely private life provides no proper stage for their action.

Every man may claim the fullest liberty to exercise his faculties compatible with the possession of like liberties by every other man.

He who is not sure of his memory, should not undertake the trade of lying. 

Absurd, irreducible; nothing - not even a profound and secret delirium of nature - could explain it. Obviously I did not know everything, I had not seen the seeds sprout, or the tree grow. But faced with this great wrinkled paw, neither ignorance nor knowledge was important: the world of explanations and reasons is not the world of existence. A circle is not absurd, it is clearly explained by the rotation of a straight segment around one of its extremities. But neither does a circle exist. This root, on the other hand, existed in such a way that I could not explain it. Reflections on a chestnut tree root.

I have no fear that the result of our experiment will be that men may be trusted to govern themselves without a master. Could the contrary of this be proved, I should conclude either that there is no god, or that he is a malevolent being.

How is it possible that the poorer classes can remain healthy and have a reasonable expectation of life under such conditions? What can one expect but that they should suffer from continual outbreaks of epidemics and an excessively low expectation of life? The physical condition of the workers shows a progressive deterioration.

So long as it is not possible to produce so much that there is enough for all, with more left over for expanding the social capital and extending the forces of production - so long as this is not possible, there must always be a ruling class directing the use of society's productive forces, and a poor, oppressed class. How these classes are constituted depends on the stage of development.

An armed insurrection ... would hinder and bring into disrepute this spiritual insurrection.

Absolute freedom mocks at justice. Absolute justice denies freedom. To be fruitful, the two ideas must find their limits in each other. 

When we have chosen the vocation in which we can contribute most to humanity, burdens cannot bend us because they are only sacrifices for all. Then we experience no meager, limited, egotistic joy, but our happiness belongs to millions, our deeds live on quietly but eternally effective, and glowing tears of noble men will fall on our ashes.

With Puritanism as the constant check upon American life, neither truth nor sincerity is possible. Nothing but gloom and mediocrity to dictate human conduct, curtail natural expression, and stifle our best impulses.

I have only two rules which I regard as principles of conduct. The first is: Have no rules. The second is: Be independent of the opinion of others.

The more one has suffered, the less one demands. To protest is a sign one has traversed no hell.

For where God built a church, there the Devil would also build a chapel...Thus is the Devil ever God's ape.

America had declared war with Spain.... It did not require much political wisdom to see that America's concern was a matter of sugar and had nothing to do with humanitarian feelings. Of course there were plenty of credulous people, not only in the country at large, but even in liberal ranks, who believed in America's claim. I could not join them. I was sure that no one, be it individual or government, engaged in enslaving and exploiting at home, could have the integrity or the desire to free people in other lands.

...there are more things to admire in men than to despise.

Relativity theory forced the abandonment, in principle, of absolute space and absolute time.

Prejudices are so to speak the mechanical instincts of men: through their prejudices they do without any effort many things they would find too difficult to think through to the point of resolving to do them.

The rosy mountain peaks laughed like high lustrous thoughts,and Helen, speechless, raised her pale hands toward the sunand joyed to feel its warm rays falling on her frozen palms.

Only those are happy who never think or, rather, who only think about life's bare necessities, and to think about such things means not to think at all. True thinking resembles a demon who muddies the spring of life or a sickness which corrupts its roots. To think all the time, to raise questions, to doubt your own destiny, to feel the weariness of living, to be worn out to the point of exhaustion by thoughts and life, to leave behind you, as symbols of your life's drama, a trail of smoke and blood - all this means you are so unhappy that reflection and thinking appear as a curse causing a violent revulsion in you.

The students of physical science are not unfrequently told that their pursuits unfit them for the estimation of moral probability. And it may be so, for I am afraid that to those who are accustomed to severe reasoning, either in the province of Science or in that of Law, reasoning from 'moral probability' is apt to be regarded as a process of accumulating inconclusive arguments, in the hope that a great heap of them may, at least, look as firm as one good demonstration.

Where danger shews it self, apprehension cannot, without stupidity, be wanting; where danger is, sense of danger should be; and so much fear as should keep us awake, and excite our attention, industry, and vigour; but not to disturb the calm use of our reason, nor hinder the execution of what that dictates.

And O! how the mind is here washed clean of all its early ingrafted Jewish superstition ! It is the most profitable and elevating reading which is possible in the world. It has been the solace of my life, and will be the solace of my death.

Some part of life - perhaps the most important part - must be left to the spontaneous action of individual impulse, for where all is system there will be mental and spiritual death.

To think that so many have succeeded in dying!

It does not matter whether the right to govern is hereditary or obtained with the consent of the governed. A State is absolute in the sense which I have in mind when it claims the right to a monopoly of all the force within the community, to make war, to make peace, to conscript life, to tax, to establish and dis-establish property, to define crime, to punish disobedience, to control education, to supervise the family, to regulate personal habits, and to censor opinions. The modern State claims all of these powers, and, in the matter of theory, there is no real difference in the size of the claim between communists, fascists, and democrats.

Then he tried to recall the lessons of Mr. Wisdom. "it is I myself, eternal Spirit, who drives this Me, the slave, along that ledge. I ought not to care whether he falls and breaks his neck or not. It is not he that is real, it is I - I - I.

Once more I realized to what an extent earthly happiness is made to the measure of man. It is not a rare bird which we must pursue at one moment in heaven, at the next in our minds. Happiness is a domestic bird found in our own courtyards.

The great secret of success is to go through life as a man who never gets used up. That is possible for him who never argues and strives with men and facts, but in all experience retires upon himself, and looks for the ultimate cause of things in himself.

Art is the symbol of the two noblest human efforts: to construct and to refrain from destruction.

The Methods of Observation of Quantity in general, are 'Numeration', which is precise by the nature of Number; the 'Measurement of Space' and 'of Time', which are easily made precise; the 'Conversion of Space and Time', by which each aids the measurement of the other. The Idea of Space becomes more clear by studying 'Geometry'; the Idea of Force, by studying 'Mechanics'; the Ideas of Likeness, of Kind, of subordination of Classes, by studying 'Natural History'.

People never remember but the computer never forgets.

Love is something more stern and splendid than mere kindness.

It is therefore correct to say that the senses do not err - not because they always judge rightly, but because they do not judge at all.
