A new development began for relativity theory after 1925 with its absorption into quantum physics. The first great success was scored by Dirac's quantum mechanical equations of the electron, which introduced a new sort of quantities, the spinors, besides the vectors and tensors into our physical theories. ...But difficulties of the gravest kind turned up when one passed from one electron or photon to the interaction among an indeterminate number of such particles. In spite of several advances a final solution of this problem is not yet in sight and may well require a deep modification of the foundation of quantum mechanics, such as would account in the same basic manner for the elementary electric charge e as relativity theory and our present quantum mechanics account for c and h.

Waste no more time arguing what a good man should be. Be one.

It is a great pity that human beings cannot find all of their satisfaction in scientific contemplativeness.

Beings who are so uniquely constituted must necessarily express themselves in other ways than ordinary men. It is impossible that with souls so differently modified, they should not carry over into the expression of their feelings and ideas the stamp of those modifications.

There can be no doubt that the Virgin Mary is in heaven. How it happened we do not know.

The pursuit of mathematics is a divine madness of the human spirit.

It is truly a marvelous thing to consider to what greatness Athens arrived in the space of one hundred years after she freed herself from the tyranny of Pisistratus; but, above all, it is even more marvelous to consider the greatness Rome reached when she freed herself from her kings. The reason is easy to understand, for it is the common good and not private gain that makes cities great. Yet, without a doubt, this common good is observed only in republics, for in them everything that promotes it is practised, and however much damage it does to this or that private individual, those who benefit from the said common good are so numerous that they are able to advance in spite of the inclination of the few citizens who are oppressed by it.

I wiped away the weeds and foam, And fetched my sea-born treasures home; But the poor, unsightly, noisome things Had left their beauty on the shore With the sun, and the sand, and the wild uproar.

In vain, therefore, should we pretend to determine any single event, or infer any cause or effect, without the assistance of observation and experience.

It is unlikely that the good of a snail should reside in its shell: so is it likely that the good of a man should?

Men are qualified for civil liberty in exact proportion to their disposition to put moral chains upon their own appetites, - in proportion as their love to justice is above their rapacity, - in proportion as their soundness and sobriety of understanding is above their vanity and presumption, - in proportion as they are more disposed to listen to the counsels of the wise and good, in preference to the flattery of knaves. Society cannot exist, unless a controlling power upon will and appetite be placed somewhere; and the less of it there is within, the more there must be without. It is ordained in the eternal constitution of things, that men of intemperate minds cannot be free. Their passions forge their fetters.

In the world as we find it, even the barest requirements of a life worth living cannot all be always met in full. Toppling a tyranny may trigger civil war. Protecting a broad range of liberal freedoms may result in the regime that guarantees them being short lived. At the same time, supporting a strong state as a bulwark against anarchy may worsen the abuse of power. Wise policy can temper these conflicts. It cannot hope to overcome them.

What a monstrous thing that a University should teach journalism! I thought that was only done at Oxford. This respect for the filthy multitude is ruining civilisation.

Everyone who has left houses or brothers or sisters or father or mother or children or fields for my sake will receive a hundred times as much and will inherit eternal life.

If it is the drive of our time, after freedom of thought is won, to pursue it to that perfection through which it changes to freedom of the will in order to realize the latter as the principle of a new era, then the final goal of education can no longer be knowledge, but the will born out of knowledge, and the spoken expression of that for which it has to strive is: the personal or free man. Truth consists in nothing other than man's revelation of himself, and thereto belongs the discovery of himself, the liberation from all that is alien, the uttermost abstraction or release from all authority, the re-won naturalness. Such thoroughly true men are not supplied by school; if they are there, they are there in spite of school.

Holy Christendom has, in my judgment, no better teacher after the apostles than St. Augustine.

The 'open' mind of the poet and artist can sense realities beyond the reach of our normal senses. The real problem is that our materialistic assumptions have a number of false premises built into them: it is only when we recognize this that we see there is no sharp dividing line between the everyday world and the invisible world of the clairvoyant.

As for Adler, I was much impressed by a personal experience. Once, in 1919, I reported to him a case which to me did not seem particularly Adlerian, but which he found no difficulty in analyzing in terms of his theory of inferiority feelings, although he had not even seen the child. Slightly shocked, I asked him how he could be so sure. "Because of my thousandfold experience," he replied; whereupon I could not help saying: "And with this new case, I suppose, your experience has become thousand-and-one-fold."

I believe that the progress of experimental science, the free intercourse of nation with nation, the unrestricted influx of commodities from countries where they are cheap, and the unrestricted efflux of labour towards countries where it is dear, will soon produce, nay, I believe that they are beginning to produce, a great and most blessed social revolution.

The human body is an instrument for the production of art in the life of the human soul.

It is said that God is always on the side of the big battalions.

For joys fall not to the rich alone, nor has he lived ill, who from birth to death has passed unknown.

There are but few points in which the English, as a people, are entitled to the moral pre-eminence with which they are accustomed to compliment themselves at the expense of other nations: but, of these points, perhaps the one of greatest importance is, that the higher classes do not lie, and the lower, though mostly habitual liars, are ashamed of lying. To run any risk of weakening this feeling, a difficult one to create, or, when once gone, to restore, would be a permanent evil too great to be incurred for so very temporary a benefit as the ballot would confer, even on the most exaggerated estimate necessity.

As soon as the land of any country has all become private property, the landlords, like all other men, love to reap where they never sowed, and demand a rent even for its natural produce.

When common words are appropriated as technical terms, their meaning and relations in common use should be retained as far as can conveniently be done.

The words of the world want to make sentences.

Patriotism is an ephemeral motive that scarcely ever outlasts the particular threat to society that aroused it.

I have only two rules which I regard as principles of conduct. The first is: Have no rules. The second is: Be independent of the opinion of others.

1) Preserve Life
2) State of war (opportunism)
3) Relativism
4) Confusion

Civilization, goodness, justice, fairness all contained inside the first option. Under # 1 (Universal Humanism):

1) Survive.
2) Don't prevent another from surviving.
3) Help the less fortunate.

The best effect of fine persons is felt after we have left their presence.

If now I...say "Stealing money is wrong," I produce a sentence which has no factual meaning - that is, expresses no proposition which can be either true or false. It is as if I had written "Stealing money!!" - where the shape and thickness of the exclamation marks show, by a suitable convention, that a special sort of moral disapproval is the feeling which is being expressed.

Saints live in flames; wise men, next to them.

The ultimate metaphysical principle is the advance from disjunction to conjunction, creating a novel entity other than the entities given in disjunction.

The superior man thinks of virtue; the small man thinks of comfort. The superior man thinks of the sanctions of law; the small man thinks of favors which he may receive.

How very little can be done under the spirit of fear.

In the history of madness, two events signal this change with singular clarity: in 1657, the founding of the Hôpital Général, and the Great Confinement of the poor; and in 1794, the liberation of the mad in chains at Bicêtre. Between these two singular and symmetrical events, something happened, whose ambiguity has perplexed historians of medicine: blind repression in an absolutist regime, according to some, and, according to others, the progressive discovery, by science and philanthropy, of madness in its positive truth. In fact, beneath these reversible meanings, a structure was taking shape, which did not undo that ambiguity but was decisive for it. This structure explains the passage from the medieval and humanist experience of madness to the experience that is our own, which confines madness in mental illness.

I am in no way facetious, nor disposed for the mirth and galliardize of company, yet in one dream I can compose a whole Comedy, behold the action, apprehend the jests, and laugh myself awake at the conceits thereof.

But since he has decided to have the impossibility of living, every misfortune is an opportunity which lays this importance of living before his eyes and obliges him to decide, once again, to die.

But true good fortune is what you make for yourself. Good fortune: good character, good intentions, and good actions.

The pleasure is only for a little moment, and it [passes] like a dream, and a man at the end thereof finds death through knowing it.

If one awakens in men the idea of freedom then the free men will incessantly go on to free themselves; if on the contrary, one only educates them, then they will at all times accommodate themselves to circumstance in the most highly educated and elegant manner and degenerate into subservient cringing souls.
