What then is time? If no one asks me, I know what it is. If I wish to explain it to him who asks, I do not know.

The Scientist must set in order. Science is built up with facts, as a house is with stones. But a collection of facts is no more a science than a heap of stones is a house.

The mixture of children and men is precisely one of the most beautiful features of aristocratic government. All roles are distributed wisely in the world: that of the young is to do good, and that of old age is to prevent evil. The impetuosity of young men, who demand only action and creation, is very useful to the State; but they are too likely to innovate and destroy, and they would do much evil without the elderly, who are there to stop them. The latter in their turn oppose even useful reforms; they are too inflexible, they do not know how to accommodate themselves to circumstances, and sometimes a twenty-year old senator can very well be placed beside another of eighty.

There is a connected set of events (light-waves) travelling outward from a centre... there are some respects in which all events are alike, and others in which they differ... We must not think of a light-wave as a 'thing', but as a connected group of rhythmical events. The mathematical characteristics of such a group can be inferred by physics, but the intrinsic character of the component events cannot be inferred.

When people were committed to the idea that in the field of religion only one plan must be adopted, bloody wars resulted. With the acknowledgment of the principle of religious freedom these wars ceased. The market economy safeguards peaceful economic co-operation because it does not use force upon the economic plans of the citizens. If one master plan is to be substituted for the plans of each citizen, endless fighting must emerge. Those who disagree with the dictator's plan have no other means to carry on than to defeat the despot by force of arms.

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.

The man whom Nature has appointed to do great things is, first of all, furnished with that openness to Nature which renders him incapable of being insincere! To his large, open, deep-feeling heart Nature is a Fact: all hearsay is hearsay; the unspeakable greatness of this Mystery of Life, let him acknowledge it or not, nay even though he seem to forget it or deny it, is ever present to him,-fearful and wonderful, on this hand and on that.

I do not think it possible to get anywhere if we start from scepticism. We must start from a broad acceptance of whatever seems to be knowledge and is not rejected for some specific reason.

Man is constituted as a speculative being; he contemplates the world, and the objects around him, not with a passive indifferent eye, but as a system disposed with order and design.

There are no whole truths; all truths are half-truths. It is trying to treat them as whole truths that plays the devil.

Compared with the greatest poets, he may be said to be the poet of unpoetical natures, possessed of quiet and contemplative tastes. But unpoetical natures are precisely those which require poetic cultivation. This cultivation Wordsworth is much more fitted to give, than poets who are intrinsically far more poets than he.

A mystic bond of brotherhood makes all men one.

In some lyceums they tell me that they have voted to exclude the subject of religion. But how do I know what their religion is, and when I am near to or far from it? I have walked into such an arena and done my best to make a clean breast of what religion I have experienced, and the audience never suspected what I was about.

How do we account for the current paranormal vogue in the popular media? Perhaps it has something to do with the millennium - in which case it's depressing to realise that the millennium is still three years away.

Never trust her at any time, when the calm sea shows her false alluring smile.

Take provocation, for instance, which is the opposite and the caricature of seduction. It says: "I know that you want to be seduced, and I will seduce you." Nothing could be worse than betraying this secret rule. Nothing could be less seductive than a provocative smile or inciteful behaviour, since both presuppose that one cannot be seduced naturally and that one needs to be blackmailed into it, or through a declaration of intent: "Let me seduce you"

But he has no fear; unconquered he looks down from a lofty height upon his sufferings.

If I were to give a simple formula or recipe for distinguishing between what I consider to be admissible plans for social reform and inadmissible Utopian blueprints, I might say: Work for the elimination of concrete evils rather than for the realization of abstract goods. Do not aim at establishing happiness by political means. Rather aim at the elimination of concrete miseries.

People don't stop things they enjoy doing just because they reach a certain age. They don't stop playing tennis just because they turn 40, they don't stop with sex just because they turn 40; they keep it up as long as they can if they enjoy it, and learning will be the same thing.

Faith is the great cop-out, the great excuse to evade the need to think and evaluate evidence. Faith is belief in spite of, even perhaps because of, the lack of evidence.

I have always said, and always will say, that the studious perusal of the sacred volume will make better citizens, better fathers, and better husbands.

In the state of nature, wrong-doing is impossible ; or, if anyone does wrong, it is to himself, not to another. For no one by the law of nature is bound to please another, unless he chooses, nor to hold anything to be good or evil, but what he himself, according to his own temperament, pronounces to be so ; and, to speak generally, nothing is forbidden by the law of nature, except what is beyond everyone's power.

Blessed is he who has found his work; let him ask no other blessedness.

Hegel ... proceeds abstractly from the pre-existence of the intellect. ... He does not appeal to the intellect within us.

To be is to be cornered.

Politics, like religion, hold up the torches of martyrdom to the reformers of error.

The awareness that we are all human beings together has become lost in war and through politics. We have reached the point of regarding each other only as members of a people either allied with us or against us and our approach; prejudice, sympathy, or antipathy are all conditioned on that. Now we must rediscover the fact that we - all together - are human beings, and that we must strive to concede to each other what moral capacity we have. Only in this way can we begin to believe that in other peoples as well as in ourselves there will arise the need for a new spirit which can be the beginning of a feeling of mutual trustworthiness toward each other.

It is impossible to feel equal respect for things that are in fact unequal unless the respect is given to something that is identical in all of them. Men are unequal in all their relations with the things of this world, without exception. The only thing that is identical in all men is the presence of a link with the reality outside the world. All human beings are absolutely identical in so far as they can be thought of as consisting of a centre, which is an unquenchable desire for good, surrounded by an accretion of psychical and bodily matter.

Heroic love is the property of those superior natures who are called insane not because they do not know, but because they over-know.

The only justification for our concepts and system of concepts is that they serve to represent the complex of our experiences; beyond this they have no legitimacy. I am convinced that the philosophers have had a harmful effect upon the progress of scientific thinking in removing certain fundamental concepts from the domain of empiricism, where they are under our control, to the intangible heights of the a priori. For even if it should appear that the universe of ideas cannot be deduced from experience by logical means, but is, in a sense, a creation of the human mind, without which no science is possible, nevertheless the universe of ideas is just as little independent of the nature of our experience as clothes are of the form of the human body. This is particularly true of our concepts of time and space, which physicists have been obliged by the facts to bring down from the Olympus of the a priori in order to adjust them and put them in a serviceable condition.

Like other human freedoms, the freedoms embodied in market institutions are justified inasmuch as they meet human needs. Insofar as they fail to do this they can reasonably be altered. This is true not only of the rights that are involved in market institutions. It is true of all human rights.

Perhaps, if prematurely we dismiss ourselves from this world, all may even have to be suffered through again - the premature birth may not contribute to the production of another being, which must be begun again from the beginning.

Democracy would be wholly valueless to the proletariat if it were not immediately used as a means for putting through measures directed against private property and ensuring the livelihood of the proletariat.

There are two kinds of truths: those of reasoning and those of fact. The truths of reasoning are necessary and their opposite is impossible; the truths of fact are contingent and their opposites are possible.

The double meaning has been given to suit people's diverse intelligence. The apparent contradictions are meant to stimulate the learned to deeper study.

Astronomy is perhaps the science whose discoveries owe least to chance, in which human understanding appears in its whole magnitude, and through which man can best learn how small he is.

The errors of the times of superstition and bigotry still hold some sway, and compel those who wish to preserve a regard to their respectability in society to an over strained demeanor; and this demeanor sometimes degenerates into hypocrisy, and is often the cause of great inconsistency. It is destructive of every open, honest, generous, and manly feeling. It disgusts many, and drives them to the opposite extreme. It is sometimes the cause of insanity. It is founded in ignorance. While erroneous customs prevail in any country, it would evince an ignorance of human nature in any individual to offend against them, until he has convinced the community of their error.

All of us need an identity which unites us with our neighbours, our countrymen, those people who are subject to the same rules and the same laws as us, those people with whom we might one day have to fight side by side to protect our inheritance, those people with whom we will suffer when attacked, those people whose destinies are in some way tied up with our own.

Ethical ideas and sentiments have to be considered as parts of the phenomena of life at large. We have to deal with man as a product of evolution, with society as a product of evolution, and with moral phenomena as products of evolution.

The Kantian philosophy left a gulf between thought and being, or between subject and object, which the Hegelian philosophy sought to bridge. The bridge was to be made by positing one universal structure of all being. Being was to be a process wherein a thing 'comprehends' or 'grasps' the various states of existence and draws them into the more or less enduring unity of its 'self,' thus actively constituting itself as 'the same' throughout all change. Everything, in other words, exists more or less as a 'subject.'

The dynamic principle of fantasy is play, a characteristic also of the child, and as such it appears inconsistent with the principle of serious work. But without this playing with fantasy no creative work has ever yet come to birth. The debt we owe to the play of imagination is incalculable. It is therefore short-sighted to treat fantasy, on account of its risky or unacceptable nature, as a thing of little worth.

The homosexual never thinks of himself when someone is branded in his presence with the name homosexual. ...His sexual tastes will doubtless lead him to enter into relationships with this suspect category, but he would like to make use of them without being likened to them. Here, too, the ban that is cast on certain men by society has destroyed all possibility of reciprocity among them. Shame isolates.

Who am I? Subject and object in one - contemplating and contemplated, thinking and thought of. As both must I have become what I am.
