Man is a tool-using animal...Without tools he is nothing, with tools he is all.

Philosophy is not the owl of Minerva that takes flight after history has been realized in order to celebrate its happy ending; rather, philosophy is subjective proposition, desire, and praxis that are applied to the event.

I believe government, organized authority, or the State is necessary only to maintain or protect property and monopoly. It has proven efficient in that function only. As a promoter of individual liberty, human well-being and social harmony, which alone constitute real order, government stands condemned by all the great men of the world...I believe - indeed, I know - that whatever is fine and beautiful in the human expresses and asserts itself in spite of government, and not because of it.

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.

The alteration of motion is ever proportional to the motive force impressed; and is made in the direction of the right line in which that force is impressed.

Religion in most countries, more or less in every country, is no longer what it was, and should be,-a thousand-voiced psalm from the heart of Man to his invisible Father, the fountain of all Goodness, Beauty, Truth, and revealed in every revelation of these; but for the most part, a wise prudential feeling grounded on mere calculation; a matter, as all others now are, of Expediency and Utility; whereby some smaller quantum of earthly enjoyment may be exchanged for a far larger quantum of celestial enjoyment. Thus Religion too is Profit, a working for wages; not Reverence, but vulgar Hope or Fear.

Like a plague, the mad spirit is sweeping the country, infesting the clearest heads and staunchest hearts with the deathly germ of militarism.

If the world should break and fall on him, it would strike him fearless.

The veneration of Mary is inscribed in the very depths of the human heart.

Cartan developed a general scheme of infinitesimal geometry in which Klein's notions were applied to the tangent plane and not to the n-dimensional manifold M itself. On the foundations of general infinitesimal geometry.

Genius does not seem to derive any great support from syllogisms. Its carriage is free; its manner has a touch of inspiration. We see it come, but we never see it walk.

I think that democratic communities have a natural taste for freedom: left to themselves, they will seek it, cherish it, and view any privation of it with regret. But for equality, their passion is ardent, insatiable, incessant, invincible: they call for equality in freedom; and if they cannot obtain that, they still call for equality in slavery.

I lie on the beach like a crocodile and let myself be roasted by the sun. I never see a newspaper and don't give a damn for what is called the world.

The only roads of enquiry there are to think of: one, that it is and that it is not possible for it not to be, this is the path of persuasion (for truth is its companion); the other, that it is not and that it must not be - this I say to you is a path wholly unknowable.

In refusing to face evil, Sinclair has gained nothing and lost a great deal; the Buddhist scripture expenses it: those who refuse to discriminate might as well be dead.

After death the sensation is either pleasant or there is none at all. But this should be thought on from our youth up, so that we may be indifferent to death, and without this thought no one can be in a tranquil state of mind. For it is certain that we must die, and, for aught we know, this very day. Therefore, since death threatens every hour, how can he who fears it have any steadfastness of soul?

Thus then does the Doctrine of Knowledge, which in its substance is the realisation of the absolute Power of intelligising which has now been defined, end with the recognition of itself as a mere Schema in a Doctrine of Wisdom, although indeed a necessary and indispensable means to such a Doctrine: - a Schema, the sole aim of which is, with the knowledge thus acquired, - by which knowledge alone a Will, clear and intelligible to itself and reposing upon itself without wavering or perplexity, is possible, - to return wholly into Actual Life; - not into the Life of blind and irrational Instinct which we have laid bare in all its nothingness, but into the Divine Life which shall become visible to us.

If good music has charms to soothe the savage breast, bad music has no less powerful spells for filling the mildest breast with rage, the happiest with horror and disgust. Oh, those mammy songs, those love longings, those loud hilarities! How was it possible that human emotions intrinsically decent could be so ignobly parodied.

The central fact for me is, I think, that the [role of the] intellectual ... cannot be played without a sense of being someone whose place it is publicly to raise embarrassing questions, to confront orthodoxy and dogma (rather than to produce them), to be someone who cannot easily be co-opted by governments or corporations, and whose raison d'être is to represent all those people and issues that are routinely forgotten or swept under the rug. Representation of the Intellectual

There will be no mass-based feminist movement as long as feminist ideas are understood only by a well-educated few.

Therefore every scribe which is instructed unto the kingdom of heaven is like unto a man that is an householder, which bringeth forth out of his treasure things new and old.

I speak the truth, not my fill of it, but as much as I dare speak; and I dare to do so a little more as I grow old.

Therefore, my dear Lucilius, begin at once to live, and count each separate day as a separate life.

No period of history has ever been great or ever can be that does not act on some sort of high, idealistic motives, and idealism in our time has been shoved aside, and we are paying the penalty for it.

Ill repute is a good thing and much the same as pain.

The simultaneous existence of opposite virtues in the soul - like pincers to catch hold of God.

Even purely intellectual progress brings about its revenges. Problems settled in a rough and ready way by rude men, absorbed in action, demand renewed attention and show themselves to be still unread riddles when men have time to think. The beneficent demon, doubt, whose name is Legion and who dwells amongst the tombs of old faiths, enters into mankind and thenceforth refuses to be cast out. Sacred customs, venerable dooms of ancestral wisdom, hallowed by tradition and professing to hold good for all time, are put to the question. Cultured reflection asks for their credentials; judges them by its own standards; finally, gathers those of which it approves into ethical systems, in which the reasoning is rarely much more than a decent pretext for the adoption of foregone conclusions.

For what is life but a play in which everyone acts a part until the curtain comes down?

For it is with the same imperialism that present-day simulators try to make the real, all of the real, coincide with their simulation models.

The family uses people, not for what they are, nor for what they are intended to be, but for what it wants them for - its own uses. It thinks of them not as what God has made them, but as the something which it has arranged that they shall be.

To be without some of the things you want is an indispensable part of happiness.

In anything fit to be called by the name of reading, the process itself should be absorbing and voluptuous; we should gloat over a book, be rapt clean out of ourselves, and rise from the perusal, our mind filled with the busiest, kaleidoscopic dance of images, incapable of sleep or of continuous thought. The words, if the book be eloquent, should run thenceforward in our ears like the noise of breakers, and the story, if it be a story, repeat itself in a thousand coloured pictures to the eye.

There is only one passion, the passion for happiness.

Everyone has a goal which appears to be great, at least to himself, and is great when deepest conviction, the innermost voice of the heart, pronounces it great. ... This voice, however, is easily drowned out, and what we thought to be inspiration may have been created by the fleeting moment and again perhaps destroyed by it. ... We must seriously ask ourselves, therefore, whether we are really inspired about a vocation, whether an inner voice approves of it, or whether the inspiration was a deception, whether that which we took as the Deity's calling to us was self-deceit. But how else could we recognize this except by searching for the source of our inspiration?

Violence and freedom are the two endpoints on the scale of power.

I think these things firearms were invented by Satan himself, for they can't be defended against with (ordinary) weapons and fists. All human strength vanishes when confronted with firearms. A man is dead before he sees what's coming.

Be afraid of the Chinese. I mean, the Chinese shoot down satellites in space; they hack into Google's computers; the Osama bin Laden people can't make their underwear blow up.

I see that sensible men and conscientious men all over the world were of one religion.

Militarism in both its forms - as war and as armed peace - is a legitimate child, a logical result of capitalism, which can only be overcome with the destruction of capitalism, and that hence whoever honestly desires world peace and liberation from the tremendous burden of armaments must also desire Socialism. Only in this way can real Social Democratic enlightenment and recruiting be carried on in connection with the armaments debate.

When Demaratus was asked whether he held his tongue because he was a fool or for want of words, he replied, "A fool cannot hold his tongue."

The truth is a trap: you can not get it without it getting you; you cannot get the truth by capturing it, only by its capturing you.

A good man with a good conscience doesn't walk so fast.

But what can be the attraction of getting to know such a tiny section of nature thoroughly, while one leaves everything subtler and more complex shyly and timidly alone? Does the product of such a modest effort deserve to be called by the proud name of a theory of the universe? In my belief the name is justified; for the general laws on which the structure of theoretical physics is based claim to be valid for any natural phenomenon whatsoever. With them, it ought to be possible to arrive at the description, that is to say, the theory, of every natural process, including life, by means of pure deduction, if that process of deduction were not far beyond the capacity of the human intellect. The physicist's renunciation of completeness for his cosmos is therefore not a matter of fundamental principle.

The only profound thinkers are the ones who do not suffer from a sense of the ridiculous.

Consider the most famous pure dystopian tale of modern times, 1984, by George Orwell (1903-1950), published in 1948 (the same year in which Walden Two was published). I consider it an abominably poor book. It made a big hit (in my opinion) only because it rode the tidal wave of cold war sentiment in the United States.

Declining from the public ways, walk in unfrequented paths.

You're either excluding the right people or including the wrong people.

What profit is there in crossing the sea and in going from one city to another? If you would escape your troubles, you need not another place but another personality. Perhaps you have reached Athens, or perhaps Rhodes; choose any state you fancy, how does it matter what its character may be? You will be bringing to it your own.

It is the furious longing to give finality to the Universe, to make it conscious and personal, that has brought us to believe in God, to wish that God may exist, to create God, in a word. To create Him, yes! This saying ought not to scandalize even the most devout theist. For to believe in God is, in a certain sense, to create Him, although He first creates us. It is He who is continually creating Himself.
