"I have resolved to confine my studies and my pen to medical subjects only. For the talents which God has not given me, I am not responsible, but those which I possess, I have hitherto cultivated and employed as diligently as my opportunities have allowed me to do ; and I shall continue to apply them with assiduity, and in tranquillity, to that profession which has constantly been the ultimate object of all my labours."
"The theory of waves has been much simplified, and somewhat extended, and their motions have been illustrated by experiments... A similar method of reasoning has been applied to the circulation of the blood, to the propagation of sound, either in fluids or in solids, and to the vibrations of musical chords; the general principle of a velocity, corresponding to half the height of a certain modulus, being shown to be applicable to all these cases: and a connexion has been established between the sound to be obtained from a given solid, and its strength in resisting a flexure of any kind; or, in the case of ice and water, between the sound in a solid and the compressibility in a fluid state. The doctrine of sound and of sounding bodies in general has also received some new illustrations, and the theory of music and of musical intervals has been particularly discussed."
"With respect to the mathematical part of optics, the curvature of the images, formed by lenses and mirrors, has been correctly investigated, and the inaccuracy of some former estimations has been demonstrated."
"In the department of , the phenomena of halos and parhelia have been explained, upon principles not entirely new, but long forgotten: the functions of the eye have been minutely examined, and the mode of its accommodation to the perception of objects at different distances ascertained: the various phenomena of coloured light have been copiously described, and accurately represented by coloured plates; and some new cases of the production of colours have been pointed out, and have been referred to the general law of double lights, by which a great variety of the experiments of former opticians have also been explained; and this law has been applied to the establishment of a theory of the nature of light, which satisfactorily removes almost every difficulty that has hitherto attended the subject."
"The theory of the tides has been reduced into an extremely simple form, which appears to agree better with all the phenomena, than the more intricate calculations which they have commonly been supposed to require."
"To call the Germans a 'nation of thinkers' is bitter irony; a nation of soldiers and shopkeepers would certainly be more correct..."
"Though it were proved that there was never an Aryan race in the past, yet we desire that in the future there may be one. This is the decisive standpoint for men of action."
"In the eyes of God all men, indeed all creatures, may be equal: but the divine law of the individual is to maintain and to defend his individuality."
"Certain anthropologists would fain teach us that all races are equally gifted; we point to history and answer: that is a lie! The races of mankind are markedly different in the nature and also in the extent of their gifts, and the Germanic races belong to the most highly gifted group, the group usually termed Aryan... Physically and mentally the Aryans are pre-eminent among all peoples; for that reason they are by right … the lords of the world. Do we not see the homo syriacus develop just as well and as happily in the position of slave as of master? Do the Chinese not show us another example of the same nature?"
"All historically great races and nations have been produced by mixing; but wherever the difference of type is too great to be bridged over, then we have mongrels. That is the case here. The crossing between Bedouin and Syrian was — from an anatomical point of view — probably worse than that between Spaniard and South American Indian."
"[the true (Vedic) religion of the Indians] was never ... an attempt to explain external, temporal things but rather represents a symbolic shaping of internal, non-mechanistic, timeless experience — there was never an attempt to prove the existence of God ... Precisely that god of the Indo-Aryan ‘whose existence cannot be proved,’ (as it says in an Upanishad), since he is not given to experience externally, but only through inner experience, is in reality the god of all inwardly religious German Christians of all times, no matter which confession they had externally to adhere to; that can be proven in the mystics and philosophers, from Erigena and Eckhart to Bohme and Kant."
"For the less Teutonic a land is, the more uncivilised it is."
"[Y]et I think that we are inclined to under-estimate our own powers [...] and to exaggerate the importance of the Jewish influence. Hand in hand with this goes the perfectly ridiculous and revolting tendency to make the Jews the general scapegoat for all the vices of our time..."
"[O]ne of the most admirable characteristics of the Jews [...] was their care to keep the race pure..."
"Their existence is sin, their existence is a crime against the holy laws of life."
"[T]hat the Jew, thanks to Ezekiel, is the teacher of all intolerance, of all fanaticism in faith, and of all murder for the sake of religion; that he only appealed to toleration where he felt himself oppressed, that he himself, on the other hand, never practised it nor dared to practise it, for his law forbade it as it forbids it today and will forbid it tomorrow."
"That Indian thought has clearly exercised a determinative influence upon Greek philosophy is now a settled fact; of course, our Hellenists and philosophers have long disputed this with the violent obstinacy of prejudiced scholars; everything was supposed to have originated autonomously in Hellas; at most the Egyptians and Semites were supposed to have exercised a shaping influence ..."
"That still today, for example, — when so many big and important things need our whole attention, when we have piled up endless treasures of thought, of poetry and above all of knowledge, of which the wisest Greeks had not the faintest idea and to a share of which every child should have a natural right ~ that today we are still compelled to waste valuable time learning every detail of the pitiful history of the Greeks, to stuff our poor brains with endless registers of names of boastful heroes ending in -ades, -atas, -enes, -eiton, &c., and, if possible, wax enthusiastic over the political fate of these cruel, short-sighted democracies, blinded with self-Jove, and based upon slavery and idleness — this is indeed a hard destiny. But if we think about it, the blame for this lies not with the Greeks but with our own narrow-mindedness."
"We have stopped up the spring that welled up in our own hearts and made ourselves dependent upon the scanty, brackish water which the beduins of the desert draw from their wells."
"I have never understood why Catholics of culture take pains to deny or to explain away the fact that the Roman Church is not only a religion but also a secular system of government, and that the Church as representative of God upon earth may eo ipso claim — and always has claimed — absolute power in all things of this world."
"We find that actual, concrete knowledge, that is, the great work of toilsome discovery, has one deadly enemy, omniscience. The Jews are a case in point; if a man possesses a sacred book, which contains all wisdom, then all further investigation is as superfluous as it is sinful: the Christian Church took over the Jewish tradition. This fastening on to Judaism, which was so fatal for our history, is being accomplished before our very eyes; it can be demonstrated step by step. The old Church Fathers, taking their stand expressly upon the Jewish Torah, are unanimous in preaching contempt of art and of science."
"The noble Moor of Spain is anything but a pure Arab of the desert, he is half a Berber (from the Aryan family) and his veins are so full of Gothic blood that even at the present day noble inhabitants of Morocco can trace their descent back to Teutonic ancestors."
"If the Mohammedan had not practised tolerance at a time when this idea was unknown to the rest of Europe, there would now be idyllic peace in the Balkan States and in Asia Minor. Here it is the Christian who throws in the leaven of discord; and with the cruelty of a ruthlessly reacting power of nature, the otherwise humane Moslem rises and destroys the disturber of his peace."
"We are not yet free of peril from the Arabs, who long seriously threatened our existence, and their creation, Mohammedanism, is the greatest of all hindrances to every progress of civilisation, hanging like a sword of Damocles over our slowly and laboriously rising culture in Europe, Asia and Africa."
"Not only the Jew, but also all that is derived from the Jewish mind, corrodes and disintegrates what is best in us."
"I say, therefore, that the men who founded Judaism were not impelled by evil, selfish motives, but goaded on by a demoniacal power."
"One does not need to have the authentic Hittite nose to be a Jew; the term Jew rather denotes a special way of thinking and feeling. A man can very soon become a Jew without being an Israelite; often it needs only to have frequent intercourse with Jews, to read Jewish newspapers, to accustom himself to Jewish philosophy, literature and art. On the other hand, it is senseless to call an Israelite a 'Jew', though his descent is beyond question, if he has succeeded in throwing off the fetters of Ezra and Nehemiah, and if the law of Moses has no place in his brain, and contempt of others no place in his heart."
"This will to live was the first thing that Judaism gave to Christianity: hence that contradiction, which even today seems to many an inexplicable riddle, between a doctrine of inner conversion, toleration and mercifulness, and a religion of exclusive self-assertion and fanatical intolerance."
"Though Mohammedanism may be the worst of all religions, as Schopenhauer asserts, who can repress a thrill of almost uncanny admiration when he sees a Mohammedan go to his death as calmly as if he were going for a walk?"
"[T]he power [...] has never disarmed, is today in certain respects stronger than ever, possesses a much better disciplined, more unconditionally submissive throng of officials than in any former century, and is only waiting for the hour when it can unscrupulously assert itself."
"Without civil intervention the free market tends to monopoly. What we should do is try to restore a truly free market, try to restore a market where there are no barriers to access and people have something other than their labour which they can trade or exchange."
"I believe in markets, but I don't believe in markets understood as private monopolies. I believe in open global, national and regional civic markets. If everybody owns and trades, and there wasn't just an exclusive, dispossessed class, there wouldn't be a radically insecure bottom twenty or thirty percent of society that causes problems for everybody else."
"Both the unlimited state and the unrestrained market have destroyed civil society, which is our world. … Civil society is something that is not the state or the market. Civil society is the world of you and I."
"The welfare state disempowered working class people people by taking away their ability to self-organise, by taking away their ability to work with each other. It atomised working class communities and also prevented innovation and aspiration for those at the bottom."
"What is actually happening now is that monoploy capitalism needs the state to disempower ordinary people's institutions and lives. What we are actually developing in modern Europe is a post-democratic society. We are creating an oligarchical elite structure where moneyed elites, the elites of industry cohabit with political elites and they move into each other's regimes and spaces. So we have now produced what I would call a market state, and the market state really just exists for the benefit of those in the top. And there is clear economic and social evidence for this, it is very clear that only those at the very top of society in the developed world have really benefited from the last thirty years."
"What we are seeing is the rise of new oligarchies. It is almost as if the 19th century is returning to the 21st century where we are going to live in a world where most of us are disempowered, most of us permanently struggle, most of us can't make ends meet, all the while a very small elite at the top is reaping vast rewards."
"The great error of the last 50 years is that conservatives think that they should unthinkingly endorse laissez -faire economics, but as presently conceived the free market destroys most of the things conservatives value; it destroys traditions, family life, societies, cultures, and established ways of doing things. The market place, as understood by contemporary neo-liberalism, is something no genuine conservative should support or endorse."
"And then the difference seems to arise from the deficient harvest, from the growth of population, from the extortion of tradesmen, from anything rather than the change of a British sovereign fresh from the Mint. Value is the most invisible and impalpable of ghosts, and comes and goes unthought of while the visible and dense matter remains as it was."
"George Boole took up Leibniz's idea, and wrote a book he called '. The laws he formulated are now called ... William Stanley Jevons heard of Boole's work, and undertook to build a machine to make calculations in Boolean algebra. He successfully designed and built such a machine, which he called the Logical Piano, apparently because it was about the size and shape of a small piano. This machine and its creator deserve much more fanfare than they have so far received. This was the first machine to do mechanical inference. Its predecessors, including the [Leibniz] Stepped Reckoner, only did arithmetic. ...The design of the machine was described in On the Mechanical Performance of Logical Inference, read before the British Royal Society in 1870."
"In a certain sense all knowledge is inductive. We can only learn the laws and relations of things in nature by observing those things. But the knowledge gained from the senses is knowledge only of particular facts, and we require some process of reasoning by which we may collect out of the facts the laws obeyed by them. Experience gives us the materials of knowledge: induction digests those materials, and yields us general knowledge. When we possess such knowledge, in the form of general propositions and natural laws, we can usefully apply the reverse process of deduction to ascertain the exact information required at any moment. In its ultimate foundation, then, all knowledge is inductive—in the sense that it is derived by a certain inductive reasoning from the facts of experience."
"I shall endeavor to show that induction is really the inverse process of deduction."
"Neither in deductive nor inductive reasoning can we add a tittle to our implicit knowledge, which is like that contained in an unread book or a sealed letter. ...Reasoning explicates or brings to conscious possession what was before unconscious. It does not create, nor does it destroy, but it transmutes and throws the same matter into a new form."
"I protest against deference to any man, whether John Stuart Mill, or Adam Smith, or Aristotle, being allowed to check inquiry. Our science has become far too much a stagnant one, in which opinions rather than experience and reason are appealed to."
"we often observe that there is abundance of capital to be had at low rates of interest, while there are also large numbers of artisans starving for want of employment."
"To me it is far more pleasant to agree than to differ; but it is impossible that one who has any regard for truth can long avoid protesting against doctrines which seem to him to be erroneous. There is ever a tendency of the most hurtful kind to allow opinions to crystallise into creeds. Especially does this tendency manifest itself when some eminent author, enjoying power of clear and comprehensive exposition, becomes recognised as an authority. His works may perhaps be the best which are extant upon the subject in question; they may combine more truth with less error than we can elsewhere meet. But "to err is human," and the best works should ever be open to criticism. If, instead of welcoming inquiry and criticism, the admirers of a great author accept his writings as authoritative, both in their excellences and in their defects, the most serious injury is done to truth. In matters of philosophy and science authority has ever been the great opponent of truth. A despotic calm is usually the triumph of error. In the republic of the sciences sedition and even anarchy are beneficial in the long run to the greatest happiness of the greatest number."
"Nature is to us like an infinite ballot-box, the contents of which are being continually drawn, ball after ball, and exhibited to us. Science is but the careful observation of the succession in which balls of various character present themselves; we register the combinations, notice those which seem to be excluded from occurrence, and from the proportional frequency of those which usually appear we infer the probable character of future drawings."
"Truth indeed is sacred; but, as Pilate said, "What is truth?" Show us the undoubted infallible criterion of absolute truth, and we will hold it as a sacred inviolable thing. But in the absence of that infallible criterion, we have all an equal right to grope about in our search of it, and no body and no school nor clique must be allowed to set up a standard of orthodoxy which shall bar the freedom of scientific inquiry."
"The whole result of continued labour is not often consumed and enjoyed in a moment; the result generally lasts for a certain length of time. We must then conceive the capital as being progressively uninvested."
"Some of the gold possessed by the Romans is doubtless mixed with what we now possess; and some small part of it will be handed down as long as the human race exists."
"I consider that interest is determined by the increment of produce which it enables a labourer to obtain, and is altogether independent of the total return which he receives for this labour."
