The Law of conservation of energy tells us we can't get something for nothing, but we refuse to believe it.

These examples... show that, in whatever proportion of its limbs the Gorilla differs from Man, the other Apes depart still more widely from the Gorilla and that, consequently, such differences of proportion can have no ordinal value.

You', the ego, live in your left brain. When we say that man is the only creature who spends 99 per cent of his time inside his own head, we mean, in fact, inside his left cerebral hemisphere. And in the basement of the left hemisphere is the library full of filing cabinets -- the stuffy room that we mistake for reality.

But now persecution is good, because it exists; every law which originated in ignorance and malice, and gratifies the passions from whence it sprang, we call the wisdom of our ancestors: when such laws are repealed, they will be cruelty and madness; till they are repealed, they are policy and caution.

Be not unwilling in what thou doest, neither selfish nor unadvised nor obstinate; let not over-refinement deck out thy thought; be not wordy nor a busybody.

I know my heart, and have studied mankind; I am not made like any one I have been acquainted with, perhaps like no one in existence; if not better, I at least claim originality, and whether Nature did wisely in breaking the mould with which she formed me, can only be determined after having read this work. 

Those who are humane achieve glory. Those who are inhumane suffer disgrace.

I see too many proofs of the imperfection of human reason, to entertain wonder or intolerance at any difference of opinion on any subject; and acquiesce in that difference as easily as on a difference of feature or form; experience having long taught me the reasonableness of mutual sacrifices of opinion among those who are to act together for any common object, and the expediency of doing what good we can, when we cannot do all we would wish.

Death cannot explain itself. The earnestness consists precisely in this, that the observer must explain it to himself.

There are some men who expose themselves to damnation so foolishly by avarice, by brutality, by debauches, by violence, by excesses, by blasphemies! ...it is always a great folly for a man to expose himself to damnation... He must despise desire and its kingdom, and aspire to that kingdom of love in which all the subjects breathe nothing but love, and desire nothing but the benefits of love.

Dialogue never ends not for lack of time or opportunity but for essential reasons.

For a long time - always, in fact - I have known that life here on earth is not what I needed and that I wasn't able to deal with it; for this reason and for this reason alone, I have acquired a touch of spiritual pride, so that my existence seems to me the degradation and the erosion of a psalm.

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

I believe in Christianity as I believe that the sun has risen. Not only because I see it, but because by it I see everything else.

In life, in true life, there can be nothing better than what is. Wanting something different than what is, is blasphemy.

Warmth, warmth, more warmth! for we are dying of cold and not of darkness. It is not the night that kills, but the frost.

May we be those who shall heal this world.

I have been overcome by the beauty and richness of our life together, those early mornings setting out, those evenings gleaming with rivers and lakes below us, still holding the last light. ... Those fields of daisies we landed on, and dusty fields and desert stretches. Memories of many skies and earths beneath us - many days, many nights of stars.

If the task of philosophy is to break the domination of words over the human mind, then my concept notation, being developed for these purposes, can be a useful instrument for philosophers. I believe the cause of logic has been advanced already by the invention of this concept notation.

In the life of the mass-order, the culture of the generality tends to conform to the demands of the average human being. Spirituality decays through being diffused among the masses when knowledge is impoverished in every possible way by rationalisation until it becomes accessible to the crude understanding of all.

The oneness of the universe, and the oneness of each element of the universe, repeat themselves to the crack of doom in the creative advance from creature to creature, each creature including in itself the whole of history and exemplifying the self-identity of things and their mutual diversities.

In fact, this infinitesimally spread-out consciousness is a direct feeling of its contents as spread out. In an infinitesimal interval we directly perceive the temporal sequence of its beginning, middle, and end... Now upon this interval follows another, whose beginning is the middle of the former, and whose middle is the end of the former. Here we have an immediate perception of the temporal sequence of its beginning, middle and end, or say, of the second, third, and fourth instants.

Being a planetary citizen does not need space travel. It means being conscious that we are part of the universe and of the earth. The most fundamental law is to recognise that we share the planet with other beings, and that we have a duty to care for our common home.

Few people can be happy unless they hate some other person, nation, or creed.

Persons of genius, it is true, are, and are always likely to be, a small minority; but in order to have them, it is necessary to preserve the soil in which they grow. Genius can only breathe freely in an atmosphere of freedom.

The texts about the future life fall into, since demonstrative scholars do not agree whether to take them in their apparent meaning or interpret them allegorically. Either is permissible. But it is inexcusable to deny the fact of a future life altogether.

In the Greek conception of parrhesia... truth-having is guaranteed by the possession of... moral qualities... required... to know... and... convey such truth...

I know that my birth is fortuitous, a laughable accident, and yet, as soon as I forget myself, I behave as if it were a capital event, indispensable to the progress and equilibrium of the world.

By electricity we have not been driven out of our senses so much as our senses have been driven out of us.

I have often wondered how it should come to pass, that every man loving himself best, should more regard other men's opinions concerning himself than his own.

Philosophy, if it cannot answer so many questions as we could wish, has at least the power of asking questions which increase the interest of the world, and show the strangeness and wonder lying just below the surface even in the commonest things of daily life.

The world evades us because it becomes itself again. That stage scenery masked by habit becomes what it is. It withdraws at a distance from us.

A wise man never loses anything, if he has himself.

Not less strong than the will to truth must be the will to sincerity. Only an age, which can show the courage of sincerity, can possess truth, which works as a spiritual force within it.

Doctors try to get rid of their patients - clergymen try to get them hooked on the medicine so that they will become addicts to the church.

The sense of justice and injustice is not deriv'd from nature, but arises artificially... from education, and human conventions.

It is love that leniently and mercifully says: I forgive you everything-if you are forgiven only little, then it is because you love only little. Justice severely sets the boundary and says: No further! This is the limit. For you there is no forgiveness, and there is nothing more to be said.

Nothing is indefensible - from the absurdest proposition to the most monstrous crime.

Who is not tempted by attractive and wide-awake children to join their sports, and crawl on all fours with them, and talk baby talk with them?

In a free system any large, popular, revolutionary movement should be able to bring about its ends by such a voluntary process. As more and more people see how it works more and more will wish to participate in or support it. And so it will grow, without being necessary to force everyone or a majority or anyone into the pattern.

For already, sometime, I have been a boy and a girl, a shrub, a bird, and a silent fish in the sea.

Someone has said that it requires less mental effort to condemn than to think. The widespread mental indolence, so prevalent in society, proves this to be only too true. Rather than to go to the bottom of any given idea, to examine into its origin and meaning, most people will either condemn it altogether, or rely on some superficial or prejudicial definition of non-essentials.

A commercial company enslaved a nation comprising two hundred millions. Tell this to a man free from superstition and he will fail to grasp what these words mean. What does it mean that thirty thousand men, not athletes but rather weak and ordinary people, have subdued two hundred million vigorous, clever, capable, and freedom-loving people? Do not the figures make it clear that it is not the English who have enslaved the Indians, but the Indians who have enslaved themselves?

We all want progress. But progress means getting nearer to the place where you want to be. And if you have taken a wrong turning, then to go forward does not get you any nearer. If you are on the wrong road, progress means doing an about-turn and walking back to the right road; in that case the man who turns back soonest is the most progressive man.

By all evidence we are in the world to do nothing.

When it is a question of money, everybody is of the same religion.

Without consciousness the mind-body problem would be much less interesting. With consciousness it seems hopeless.

My new trade of nail-making is to me in this country what an additional title of nobility or the ensigns of a new order are in Europe.
