Bold ideas, unjustified anticipations, and speculative thought, are our only means for interpreting nature: our only organon, our only instrument, for grasping her. And we must hazard them to win our prize. Those among us who are unwilling to expose their ideas to the hazard of refutation do not take part in the scientific game.

No matter that we may mount on stilts, we still must walk on our own legs. And on the highest throne in the world, we still sit only on our own bottom.

Be ruled by time, the wisest counsellor of all.

The ethic of Reverence for Life prompts us to keep each other alert to what troubles us and to speak and act dauntlessly together in discharging the responsibility that we feel. It keeps us watching together for opportunities to bring some sort of help to animals in recompense for the great misery that men inflict upon them, and thus for a moment we escape from the incomprehensible horror of existence.

He was a man born into a world dominated by scientific materialism. His objection to this materialism was not merely intellectual, or even egotistical (the feeling 'If the world is wholly material, then I can't be very important'). It was the feeling that man is cut off from his inner powers by this superficial attitude.

Form no covetous desire, so that the demon of greediness may not deceive thee, and the treasure of the world may not be tasteless to thee.

If... it be supposed that another way of measuring time is adopted... enunciation of the law would be... translated into another language... much less simple. So that the definition implicitly adopted by the astronomers may be summed up..: Time should be so defined that the equations of mechanics may be as simple as possible... [i.e.,] there is not one way of measuring time more true... only more convenient.

The best life is the one in which the creative impulses play the largest part and the possessive impulses the smallest.

How can a man be said to have a country where he has no right to a square inch of soil...

That we are overdone with banking institutions which have banished the precious metals and substituted a more fluctuating and unsafe medium, that these have withdrawn capital from useful improvements and employments to nourish idleness, that the wars of the world have swollen our commerce beyond the wholesome limits of exchanging our own productions for our own wants, and that, for the emolument of a small proportion of our society who prefer these demoralizing pursuits to labors useful to the whole, the peace of the whole is endangered and all our present difficulties produced, are evils more easily to be deplored than remedied.

Before mass leaders seize the power to fit reality to their lies, their propaganda is marked by its extreme contempt for facts as such, for in their opinion fact depends entirely on the power of man who can fabricate it.

Marxism exists in nineteenth-century thought as a fish exists in water; that is, it ceases to breathe anywhere else.

A metaphysics of morals is therefore indispensably necessary, not merely because of a motive to speculation - for investigating the source of the practical basic principles that lie a priori in our reason - but also because morals themselves remain subject to all sorts of corruption as long as we are without that clue and supreme norm by which to appraise them correctly...

History a distillation of Rumour.

It is impossible that evils should be done away with, for there must always be something opposed to the good; and they must inevitably hover about mortal nature and this earth. Therefore we ought to try to escape from earth to the dwelling of the gods as quickly as we can; and to escape is to become like God, so far as this is possible, God is in no wise and in no manner unrighteous, but utterly and perfectly righteous, and there is nothing so like him as that one of us who in turn becomes most nearly perfect in righteousness.

Much reading after a certain age diverts the mind from its creative pursuits. Any man who reads too much and uses his own brain too little falls into lazy habits of thinking, just as the man who spends too much time in the theaters is apt to be content with living vicariously instead of living his own life.

I don't care for the applause one gets by saying what others are thinking; I want actually to change people's thoughts. Power over people's minds is the main personal desire of my life; and this sort of power is not acquired by saying popular things.

Recalling all the erroneous things that doctors have been able to say about sex or madness does us a fat lot of good. I think that what is currently politically important is to determine the regime of verediction established at a given moment ... on the basis of which you can now recognize, for example, that doctors in the nineteenth century said so many stupid things about sex. ... It is not so much the history of the true or the history of the false as the history of verediction which has a political significance.

The ultimate most holy form of theory is action. Not to look on passively while the spark leaps from generation to generation, but to leap and to burn with it!

If we owe to it [civil society] any duty, it is not subject to our will. Duties are not voluntary. Duty and will are even contradictory terms. Now though civil society might be at first a voluntary act (which in many cases it undoubtedly was) its continuance is under a permanent standing covenant, coexisting with the society; and it attaches upon every individual of that society, without any formal act of his own. This is warranted by the general practice, arising out of the general sense of mankind.

Intolerance is the besetting sin of moral fervour.

Just as a vagrant accused of stealing a carrot from a field stands before a comfortably seated judge who keeps up an elegant flow of queries, comments and witticisms while the accused is unable to stammer a word, so truth stands before an intelligence which is concerned with the elegant manipulation of opinions.

She with one breath attunes the spheres, And also my poor human heart.

There is nothing more visible than what is secret, and nothing more manifest than what is minute. Therefore the superior man is watchful over himself, when he is alone.

In England, and in all Roman Catholic countries, the lottery of the church is in reality much more advantageous than is necessary.

Our liberty is neither Greek nor Roman; but essentially English. It has a character of its own,-a character which has taken a tinge from the sentiments of the chivalrous ages, and which accords with the peculiarities of our manners and of our insular situation. It has a language, too, of its own, and a language singularly idiomatic, full of meaning to ourselves, scarcely intelligible to strangers.

Pure Mathematics is the class of all propositions of the form "p implies q," where p and q are propositions containing one or more variables, the same in the two propositions, and neither p nor q contains any constants except logical constants. And logical constants are all notions definable in terms of the following: Implication, the relation of a term to a class of which it is a member, the notion of such that, the notion of relation, and such further notions as may be involved in the general notion of propositions of the above form. In addition to these, mathematics uses a notion which is not a constituent of the propositions which it considers, namely the notion of truth.

His power to adore is responsible for all his crimes: a man who loves a god unduly forces other men to love his god, eager to exterminate them if they refuse.

POLITICAL economy, considered as a branch of the science of a statesman or legislator, proposes two distinct objects: first, to provide a plentiful revenue or subsistence for the people, or more properly to enable them to provide such a revenue or subsistence for themselves; and secondly, to supply the state or commonwealth with a revenue sufficient for the public services. It proposes to enrich both the people and the sovereign.

What is this wide-spread component of the surface of the earth? and whence did it come? You may think this no very hopeful inquiry. You may not unnaturally suppose that the attempt to solve such problems as these can lead to no result, save that of entangling the inquirer in vague speculations, incapable of refutation and of verification. If such were really the case, I should have selected some other subject than a "piece of chalk" for my discourse. But, in truth, after much deliberation, I have been unable to think of any topic which would so well enable me to lead you to see how solid is the foundation upon which some of the most startling conclusions of physical science rest.

In order to obey God, one must receive his commands. How did it happen that I received them in adolescence, while I was professing atheism? To believe that the desire for good is always fulfilled - that is faith, and whoever has it is not an atheist.

The yogi, absorbed in contemplation, contributes in his degree to creation: he breathes a divine perfume, he hears wonderful things. Divine forms traverse him without tearing him, and, united to the nature which is proper to him, he goes, he acts as animating original matter. To some extent, and at rare intervals even I am a yogi .

If I understand at all the true Spirit of the present contest, We are engaged in a Civil War ... I consider the Royalists of France, or, as they are (perhaps more properly) called, the Aristocrates, as of the party which we have taken in this civil war.

I do not believe that civilizations have to die...Civilization is not an organism. It is a product of wills.

When speaking of the new testament that you should read all the histories of Christ, as well of those whom a council of ecclesiastics have decided for us to be Pseudo-evangelists, as those they named Evangelists. Because these Pseudo-evangelists pretended to inspiration as much as the others, and you are to judge their pretensions by your own reason, & not by the reason of those ecclesiastics. Most of these are lost. There are some however still extant, collected by Fabricius which I will endeavor to get & send you.

Some philosophers fail to distinguish propositions from judgments; ... But in the real world it is more important that a proposition be interesting than that it be true. The importance of truth is that it adds to interest.

The state of mind which enables a man to do work of this kind is akin to that of the religious worshiper or the lover; the daily effort comes from no deliberate intention or program, but straight from the heart.

Commoners are weightless. But he was a royal bon vivant who, no matter what, always weighed 125 kilos. I would be very surprised if he didn't have a few pounds left.

A mind does not receive truth as a chest receives jewels that are put into it, but as the stomach takes up food into the system. It is no longer food, but flesh, and is assimilated. The appetite and the power of digestion measure our right to knowledge. He has it who can use it. As soon as our accumulation overruns our invention or power to use, the evils of intellectual gluttony begin,- congestion of the brain, apoplexy, and strangulation.

Philosophers today are as fond as ever of apriori arguments with ethical conclusions. One reason such arguments are always unsatisfying is that they always prove too much; when a philosopher 'solves' an ethical problem for one, one feels as if one had asked for a subway token and been given a passenger ticket valid for the first interplanetary passenger-carrying space ship instead.

..Whenever it ceases to be true that mankind, as a rule, prefer themselves to others, and those nearest to them to those more remote, from that moment Communism is not only practicable, but the only defensible form of society...

Sleep is a death; oh, make me try By sleeping what it is to die, And as gently lay my head On my grave as now my bed.

If you are going to build something in the air it is always better to build castles than houses of cards.

Every intellectual effort sets us apart from the commonplace, and leads us by hidden and difficult paths to secluded spots where we find ourselves amid unaccustomed thoughts.

The second office of the government is honorable and easy, the first is but a splendid misery.

The silent organ loudest chants The master's requiem.

Lamachus chid a captain for a fault; and when he had said he would do so no more, "Sir," said he, "in war there is no room for a second miscarriage." Said one to Iphicrates, "What are ye afraid of?" "Of all speeches," said he, "none is so dishonourable for a general as 'I should not have thought of it.'"
