That which makes the man no worse than he was makes his life no worse: it has no power to harm, without or within.

God is not needed to create guilt or to punish. Our fellow men suffice, aided by ourselves.

It was not delight, not wonder that arose among us, it was the peace of heaven. A thousand times have I said it to her and to myself: the most beautiful is also the most sacred. And such was everything in her. Like her singing, even so was her life.

After the publication of my dialogues, I was summoned to Rome by the Congregation of the holy Office, where, being arrived on the 10th of February 1633, I was subjected to the infinite clemency of that tribunal, and of the Sovereign Pontiff, Urban the Eighth; who, notwithstanding, thought me deserving of his esteem.

Schopenhauer argues that the empirical world exists only as a representation: 'every object, whatever its origin, is, as object, already conditioned by the subject, and thus is essentially only the subject's representation.' A representation is a subjective state that has been ordered according to space, time and causality - the primary forms of sensibility and understanding. So long as we turn our thoughts towards the natural world, and search for the thing-in-itself behind the representation is futile. Every argument and every experience leads only to the same end: the system of representations, standing like a veil between the subject and the thing-in-itself. No scientific investigation can penetrate the veil; and yet it is only a veil, Schopenhauer affirms, a tissue of illusions which we can, if we choose, penetrate by other means. The way to penetrate the veil was stumbled upon by Kant.

Basically-I speak of life as it is and not of abstract philosophical constructs-life is only bearable because one does not go to the end; doing something is only possible when one has particular illusions and that holds also for friendships, for everything.

Some books are to be tasted, others to be swallowed, and some few to be chewed and digested; that is, some books are to be read only in parts; others to be read, but not curiously; and some few to be read wholly, and with diligence and attention.

Manners are of more importance than laws. The law can touch us here and there, now and then. Manners are what vex or soothe, corrupt or purify, exalt or debase, barbarize or refine us, by a constant, steady, uniform, insensible operation like that of the air we breathe in.

Naturally, every age thinks that all ages before it were prejudiced, and today we think this more than ever and are just as wrong as all previous ages that thought so. How often have we not seen the truth condemned! It is sad but unfortunately true that man learns nothing from history.

Totalitarianism in power invariably replaces all first-rate talents, regardless of their sympathies, with those crackpots and fools whose lack of intelligence and creativity is still the best guarantee of their loyalty.

Words are deeds.

Even when labor is subjugated by capital it always necessarily maintains its own autonomy, and this ever more clearly true today with respect to the new immaterial, cooperative and collaborative forms of labor. This relationship is not isolated to the economic terrain but, as we will argue later, spills over into the biopolitical terrain of society as a hole, including military conflicts. In any case, we should recognize here that even in asymmetrical conflicts victory in terms of complete domination is not possible. All that can be achieved is a provisional and limited maintenance of control and order that must constantly be policed and preserved. Counterinsurgency is a full-time job.

When going to the temple to adore Divinity neither say nor do any thing in the interim pertaining to the common affairs of life.

As the few adepts in such things well know, universal morality is to be found in little everyday penny-events just as much as in great ones. There is so much goodness and ingenuity in a raindrop that an apothecary wouldn't let it go for less than half-a-crown.

In adversity, remember to keep an even mind.

The species with eyes appears suddenly, capriciously as it were, and it is this species which changes the environment by creating its visible aspect. The eye does not come into being because it is needed. Just the contrary; because the eye appears it can henceforth be applied as a serviceable instrument. Each species builds up its stock of useful habits by selecting among, and taking advantage of, the innumerable useless actions which a living being performs out of sheer exuberance.

All those events in history were such dramas as we see now, only with different actors.

Out of love, God becomes man. He says: Here you see what it is to be a human being; but he adds: Take care, for I am also God - blessed is he who takes no offense at me. 

Has any man, or any society of men, a truth to speak, a piece of spiritual work to do; they can nowise proceed at once and with the mere natural organs, but must first call a public meeting, appoint committees, issue prospectuses, eat a public dinner; in a word, construct or borrow machinery, wherewith to speak it and do it. Without machinery, they were hopeless, helpless.

History is nothing but assisted and recorded memory. It might almost be said to be no science at all, if memory and faith in memory were not what science necessarily rest on. In order to sift evidence we must rely on some witness, and we must trust experience before we proceed to expand it. The line between what is known scientifically and what has to be assumed in order to support knowledge is impossible to draw. Memory itself is an internal rumour; and when to this hearsay within the mind we add the falsified echoes that reach us from others, we have but a shifting and unseizable basis to build upon. The picture we frame of the past changes continually and grows every day less similar to the original experience which it purports to describe.

We do not think good metaphors are anything very important, but I think that a good metaphor is something even the police should keep an eye on...

Lastly, there are Idols which have immigrated into men's minds from the various dogmas of philosophies, and also from wrong laws of demonstration. These I call Idols of the Theater, because in my judgment all the received systems are but so many stage plays, representing worlds of their own creation after an unreal and scenic fashion.

A reflective, contented mind is the best possession.

I seem to myself, among civilised men, an intruder, a troglodyte enamored of decrepitude, plunged into subversive prayers.

The genius of democracies is seen not only in the great number of new words introduced but even more in the new ideas they express.

Tyranny is just what one can develop a taste for, since it so happens that man prefers to wallow in fear rather than to face the anguish of being himself.

Confession should be only in secret before God, who knows everything anyway, and thus it could remain hidden in one's innermost being. But at a dinner and a woman! A dinner-it is not some hidden, remote place, nor is the lighting dim, nor is the mood like that among graves, nor are the listeners silent or invisibly present.

The soul follows the progress of the body, as it does the progress of education.

Scientific beliefs are supported by evidence, and they get results. Myths and faiths are not and do not.

Roemer used eclipses of the satellites of Jupiter, and sought how much the event fell behind its prediction. But... this prediction is made... by... astronomic laws; for instance Newton's... The velocity of light... is adopted, such that the astronomic laws compatible with this value may be as simple as possible.

As Christ had recommended peace during the whole of his life, mark with what anxiety he enforces it at the approach of his dissolution. Love one another, says he; as I have loved you, so love one another; and again, my peace I give unto you, my peace I leave you. Do you observe the legacy he leaves to those whom he loves? Is it a pompous retinue, a large estate, or empire? Nothing of this kind. What is it then? Peace he giveth, his peace he leaveth; peace, not only with our near connections, but with enemies and strangers!

When it comes to consideration of how to do well in running the city, which must proceed entirely through justice and soundness of mind.

Out of the crooked timber of humanity, no straight thing was ever made.

On the whole, the scientist is better off if he collects his facts by accident, little by little, so he can study them before he tries to fit them into a jigsaw puzzle, This is how the late Tom Lethbridge came to arrive at his theories about other dimensions of reality. It is also how Guy Lyon Playfair came to develop his own theories about the nature of the poltergeist.

Men looke not at the greatnesse of the evill past, but the greatnesse of the good to follow.

Has woman the same rights in the state which man has? This question may appear ridiculous to many. For if the only ground of all legal rights is reason and freedom, how can a distinction exist between two sexes which possess both the same reason and the same freedom. Nevertheless, it seems that, so long as men have lived, this has been differently held, and the female sex seems not to have been placed on a par with the male sex in the exercise of its rights. Such a universal sentiment must have a ground, to discover which was never a more urgent problem than in our days.

I would have written a shorter letter, but I did not have the time.

The man of flesh and bone; the man who is born, suffers, and dies-above all, who dies; the man who eats and drinks and plays and sleeps and thinks and wills; the man who is seen and heard; the brother, the real brother.

What man can you show me who places any value on his time, who reckons the worth of each day, who understands that he is dying daily?

Democracy is still upon its trial. The civic genius of our people is its only bulwark.
