Drunkenness is temporary suicide.

The devil is an angel too.

A mind of slow apprehension is therefore not necessarily a weak mind. The one who is alert with abstractions is not always profound, he is more often very superficial.

The cup of life is not so shallow

That we have drained the best 

That all the wine at once we swallow 

And lees make all the rest.

It is rare that the public sentiment decides immorally or unwisely, and the individual who differs from it ought to distrust and examine well his own opinion.

Methinks I am like a man, who having struck on many shoals, and having narrowly escap'd shipwreck in passing a small frith, has yet the temerity to put out to sea in the same leaky weather-beaten vessel, and even carries his ambition so far as to think of compassing the globe under these disadvantageous circumstances.

Morality is everywhere the same for all men, therefore it comes from God; sects differ, therefore they are the work of men.

There is geometry in the humming of the strings. There is music in the spacings of the spheres.

I was sitting in a chair in the patent office at Bern when all of sudden a thought occurred to me: If a person falls freely he will not feel his own weight. I was startled. This simple thought made a deep impression on me. It impelled me toward a theory of gravitation.

A good judge condemns wrongful acts, but does not hate them.

Examine the man who lives in misery because he does not shine above other men; who goes about producing himself, pruriently anxious about his gifts and claims; struggling to force everybody, as it were begging everybody for God's sake, to acknowledge him a great man, and set him over the heads of men! Such a creature is among the wretchedest sights seen under this sun. A great man? A poor morbid prurient empty man; fitter for the ward of a hospital, than for a throne among men. I advise you to keep out of his way. He cannot walk on quiet paths; unless you will look at him, wonder at him, write paragraphs about him, he cannot live. It is the emptiness of the man, not his greatness. Because there is nothing in himself, he hungers and thirsts that you would find something in him. In good truth, I believe no great man, not so much as a genuine man who had health and real substance in him of whatever magnitude, was ever much tormented in this way.

Philosophy ... is a science, and as such has no articles of faith; accordingly, in it nothing can be assumed as existing except what is either positively given empirically, or demonstrated through indubitable conclusions.

For this reason those who are tossed about at sea, who proceed uphill and downhill over toilsome crags and heights, who go on campaigns that bring the greatest danger, are heroes and front-rank fighters; but persons who live in rotten luxury and ease while others toil, are mere turtle-doves safe only because men despise them.

Inasmuch as love grows in you, in so much beauty grows; for love is itself the beauty of the soul.

I: My consciousness of the object is only a yet unrecognised consciousness of my production of the representation of an object. Of this production I know no more than that it is I who produce, and thus is all consciousness no more than a consciousness of myself, and so far perfectly comprehensible. Am I in the right? Spirit. Perfectly so ; but whence then is derived the necessity and universality thou hast ascribed to these propositions, to that of causality for instance?

Never read any book that is not a year old.

A man may be humble through vainglory.

No one realizes how beautiful it is to travel until he comes home and rests his head on his old, familiar pillow.

When you move into a new area, a new territory and learn a new language, the language is not a new subject, it is an environment, it is total.

"Then those people are right who say that Heaven and Hell are only states of mind?" "Hush," he said sternly. "Do not blaspheme. Hell is a state of mind - ye never said a truer word. And every state of mind, left to itself, every shutting up of the creature within the dungeon of its own mind - is, in the end, Hell. But Heaven is not a state of mind. Heaven is reality itself. All that is fully real is Heavenly."

An evil may be real, tho' its cause has no relation to us: It may be real, without being peculiar: It may be real, without shewing itself to others: It may be real, without being constant: And it may be real, without falling under the general rules. Such evils as these will not fail to render us miserable, tho' they have little tendency to diminish pride: And perhaps the most real and the most solid evils of life will be found of this nature.

He is dead, and my hatred has died with him.

I am firmly convinced, therefore, that to set up a republic which is to last a long time, the way to set about it is to constitute it as Sparta and Venice were constituted; to place it in a strong position, and so to fortify it that no one will dream of taking it by a sudden assault; and, on the other hand, not to make it so large as to appear formidable to its neighbors. It should in this way be able to enjoy its form of government for a long time. For war is made on a commonwealth for two reasons: to subjugate it, and for fear of being subjugated by it.

I feel sure that the police are helping us more than I could do in ten years. They are making more anarchists than the most prominent people connected with the anarchist cause could make in ten years. If they will only continue I shall be very grateful; they will save me lots of work.

The universities are schools of education, and schools of research. But the primary reason for their existence is not to be found either in the mere knowledge conveyed to the students or in the mere opportunities for research afforded to the members of the faculty. Both these functions could be performed at a cheaper rate, apart from these very expensive institutions. Books are cheap, and the system of apprenticeship is well understood. So far as the mere imparting of information is concerned, no university has had any justification for existence since the popularization of printing in the fifteenth century. Yet the chief impetus to the foundation of universities came after that date, and in more recent times has even increased. The justification for a university is that it preserves the connection between knowledge and the zest of life, by uniting the young and the old in the imaginative consideration of learning.

We do not merely study the past: we inherit it, and inheritance brings with it not only the rights of ownership, but the duties of trusteeship. Things fought for and died for should not be idly squandered. For they are the property of others, who are not yet born.

Good taste is either that which agrees with my taste or that which subjects itself to the rule of reason. From this we can see how useful it is to employ reason in seeking out the laws of taste.

We do not have and cannot have any means of discovering whether or not we are carried along in a uniform motion of translation.

The doctrines of Jesus are simple, and tend all to the happiness of man.

The dyad gets its name from passing through or asunder; for the dyad is the first to have separated itself from the monad, whence also it is called "daring." For when the monad manifests unification, the dyad steals in and manifests separation.

One might naively suppose that a negative utilitarian would welcome human extinction. But only (trans)humans - or our potential superintelligent successors - are technically capable of phasing out the cruelties of the rest of the living world on Earth. And only (trans)humans - or rather our potential superintelligent successors - are technically capable of assuming stewardship of our entire Hubble volume.

In the realm of physics it is perhaps only the theory of relativity which has made it quite clear that the two essences, space and time, entering into our intuition, have no place in the world constructed by mathematical physics. Colours are thus "really" not even æther-vibrations, but merely a series of values of mathematical functions in which occur four independent parameters corresponding to the three dimensions of space, and the one of time.

I care little about the sword: I will allow a thing to struggle for itself in this world, with any sword or tongue or implement it has, or can lay hold of. We will let it preach, and pamphleteer, and fight, and to the uttermost bestir itself, and do, beak and claws, whatsoever is in it; very sure that it will, in the long-run, conquer nothing which does not deserve to be conquered. What is better than itself, it cannot put away, but only what is worse. In this great Duel, Nature herself is umpire, and can do no wrong: the thing which is deepest-rooted in Nature, what we call truest, that thing and not the other will be found growing at last.

The possibility of democracy on a global scale is emerging today for the very first time.

Nothing is so difficult as not deceiving oneself.

That the outer man is a picture of the inner, and the face an expression and revelation of the whole character, is a presumption likely enough in itself, and therefore a safe one to go on; borne out as it is by the fact that people are always anxious to see anyone who has made himself famous .... Photography ... offers the most complete satisfaction of our curiosity.

Besides, we should never attempt to balance anybody's misery against somebody else's happiness.

What to think of other people? I ask myself this question each time I make a new acquaintance. So strange does it seem to me that we exist, and that we consent to exist.

Religion is not 'doctrinal knowledge,' but wisdom born of personal experience.

Broadly stated, the task is to replace the global rationality of economic man with a kind of rational behavior that is compatible with the access to information and the computational capacities that are actually possessed by organisms, including man, in the kinds of environments in which such organisms exist.

If we want eternal life, then we'll need to rewrite our bug-ridden genetic code and become god-like. "May all that have life be delivered from suffering", said Gautama Buddha. It's a wonderful sentiment. Sadly, only hi-tech solutions can ever eradicate suffering from the living world. Compassion alone is not enough.

There is less trouble and trauma involved in writing a new piece than in trying to salvage an unsatisfactory old one.

All true metaphysics is taken from the essential nature of the thinking faculty itself, and therefore in nowise invented, since it is not borrowed from experience, but contains the pure operations of thought, that is, conceptions and principles à priori, which the manifold of empirical presentations first of all brings into legitimate connection, by which it can become empirical knowledge, i.e. experience. ...mathematical physicists were thus quite unable to dispense with such metaphysical principles...

The encouragement of light-mindedness about traditional philosophical topics serves the same purposes as does the encouragement of light-mindedness about traditional theological topics. Like the rise of large market economies, the increase in literacy, the proliferation of artistic genres, and the insouciant pluralism of contemporary culture, such philosophical superficiality and light-mindedness helps along the disenchantment of the world. It helps make the world's inhabitants more pragmatic, more tolerant, more liberal, more receptive to the appeal of instrumental rationality.
