Deists

"He has just returned from Italy, and delights to talk of it,—thinks it, next to England, the finest country in the world, and the society of Rome surpassed only by that of London, and says he should not die contented without going there again."

"I breakfasted this morning with Sir Humphry Davy, of whom we have heard so much in America. He is now about thirty—three, but with all the freshness and bloom of five-and-twenty, and one of the handsomest men I have seen in England. He has a great deal of vivacity,—talks rapidly, though with great precision, and is so much interested in conversation, that his excitement amounts to nervous impatience, and keeps him in constant motion."

"It was fortunate for science that Mr Davy survived this severe malady without any injury to his constitution, or any diminution of his mental powers. He resumed his enquiries with his wonted ardour, and by the liberality of the managers and principal members of the Royal Institution, he was furnished with the means of pursuing them with success. During his convalescence, a voltaic battery of 600 double plates, each four inches square, was constructed and placed at his disposal; and not long afterwards, when a more powerful apparatus was thought desirable, the munificence of a few individuals supplied him with another battery of no less than 2000 plates. This powerful artillery was now directed against the earths; but the task of these analyses was more difficult than he expected."

"While he was recording these splendid discoveries in his second Bakerian lecture, Mr Davy was thrown into a state of fever, and laboured under the deepest apprehension that he would die before he had finished his paper. This state of his mind was the prelude to a severe and long-protracted disease, which his friend and physician Dr Babington considered as the result of over-fatigue and excitement from his experimental labours and discoveries. During five weeks 'he struggled between life and death,' and it was not till the end of nine weeks that his convalescence commenced. The anxious enquiries of all ranks exhibited the personal regard which he commanded, and the public importance which was attached to his recovery."

"These grand discoveries, which some ascribed to the 'enormous batteries which were placed in his hands,' were the result of his intellectual powers, not of fortuitous circumstances. His voltaic battery was within the reach of many of the chemists of Europe; and consisted, in fact, of three different batteries united, one of 24 plates of copper and zinc, 12 inches square, another of 100 plates of 6 inches, and another of 150 plates of 4 inches."

"The delight which Mr Davy experienced when he first saw the minute globules of ' (the new metal) burst through the crust of potash, and take fire as they entered the atmosphere, was witnessed by his relative and assistant Mr . 'He could not contain his joy—he actually danced about the room in ecstatic delight, and some little time was required for him to compose himself sufficiently to continue the experiment.'"

"In September, 1807, our illustrious chemist applied his great principle to the analyses of potash, the vegetable alkali. Some had supposed it to consist of lime and hydrogen; others conjectured that it might contain nitrogen; and Mr Davy himself conceived that it might consist of phosphorus, or sulphur united to nitrogen. After failing with strong aqueous solutions, and also with dry potash, from its being a non-conductor, he employed fused potash, and in this case inflammable matter was separated by the voltaic influence. He then tried 'a piece of potash moistened, and in this instance inflammable matter was developed.' On the 6th of October he found that the matter instantly burned when it touched water, and swam on its surface, reproducing potash.' In dry oxygen gas likewise it burnt into 'perfectly dry potash.' In like manner, Mr Davy succeeded in decomposing soda; and when he had thus proved that the two fixed alkalis were metallic oxides, he immediately supposed that the earths, which were so much more like to metallic oxides than the fixed alkalis, would be easily decomposed."

"I need only remind you of Davy's great researches: nitrous oxide; electric conduction and decomposition—resulting, on the one hand, in the separation of potassium and sodium, the decomposition of the earths following as a necessary consequence, and on the other in the electro-chemical theory; iodine and chlorine—resulting in the extension and confirmation of the word element, the discovery of the so-called hydrogen acids, and the important modification of the French theory of the constitution of acids; the investigation of gaseous explosion and of flame, and the invention of the safety lamp. These are the contributions to science which stand out more prominently in connection with Davy. But over and above all this is the peculiar manner of his discoveries. He was no patient plodder. He did not elaborate his work in minute detail. He dashed it off in broad masses; but just on that account there has never been anyone to follow up his investigations. Davy's mantle fell on no one, not even on Faraday."

"Sir Humphry Davy Abominated gravy. He lived in the odium Of having discovered Sodium."

"Berthollet's conclusion that chlorine is oxymuriatic acid was universally accepted until Gay-Lussac and Thénard in 1809 endeavoured to decompose the gas and failed. They concluded that it contained water because it yielded water when passed over litharge. Their researches read to the Institute in 1809 led Davy to investigate muriatic acid (hydrochloric acid) gas, which in 1808 he had shown to be decomposed by potassium, with evolution of hydrogen. In 1810 he proved that chlorine is an element, and that muriatic acid gas is a compound of chlorine and hydrogen. He thus overturned the oxygen-acid theory, and demonstrated that muriates are compounds of metals with chlorine. He pointed to the fact that some acids, such as sulphuretted hydrogen, contain no oxygen, and argued that muriatic acid gas was one of these, chlorine in it taking the place of oxygen. ...The conclusions of Davy were at first doubted, but when iodine and bromine were also discovered, Gay-Lussac and his followers adopted Davy's views. The latter worked out fluorine, and proved that hydrofluoric acid (HF) contains no oxygen. Berzelius also opposed Davy until the discovery of iodine, but embraced the latter's opinion in 1820."

"Davy held that if the battery is strong enough any compound may be decomposed, and that chemical affinity is merely a form of electric attraction. He vigorously put his theory into practice..."

"Nothing is so fatal to the progress of the human mind as to suppose that our views of science are ultimate; that there are no mysteries in nature; that our triumphs are complete, and that there are no new worlds to conquer."

"I envy no quality of the mind or intellect in others; not genius, power, wit, nor fancy; but, if I could choose what would be most delightful, and, I believe, most useful to me, I should prefer a firm religious belief to every other blessing."

"It is surely a pure delight to know, how and by what processes this earth is clothed with verdure and life, how the clouds, mists and rain are formed, what causes all the changes of this terrestrial system of things, and by what divine laws order is preserved amidst apparent confusion. It is a sublime occupation to investigate the cause of the tempest and the volcano, and to point out their use in the economy of things, — to bring the lightning from the clouds and make it subservient to our experiments, — to produce as it were a microcosm in the laboratory of art, and to measure and weigh those invisible atoms, which, by their motions and changes according to laws impressed upon them by the Divine Intelligence, constitute the universe of things. The true chemical philosopher sees good in all the diversified forms of the external world. Whilst he investigates the operations of infinite power guided by infinite wisdom, all low prejudices, all mean superstitions disappear from his mind. He sees man an atom amidst atoms fixed upon a point in space; and yet modifying the laws that are around him by understanding them; and gaining, as it were, a kind of dominion over time, and an empire in material space, and exerting on a scale infinitely small a power seeming a sort of shadow or reflection of a creative energy, and which entitles him to the distinction of being made in the image of God and animated by a spark of the divine mind. Whilst chemical pursuits exalt the understanding, they do not depress the imagination or weaken genuine feelings; whilst they give the mind habits of accuracy, by obliging it to attend to facts, they likewise extend its analogies; and, though conversant with the minute forms of things, they have for their ultimate end the great and magnificent objects of nature. They regard the formation of a crystal, the structure of a pebble, the nature of a clay or earth; and they apply to the causes of the diversity of our mountain chains, the appearances of the winds, thunder-storms, meteors, the earthquake, the volcano, and all those phenomena which offer the most striking images to the poet and the painter. They keep alive that inextinguishable thirst after knowledge, which is one of the greatest charactics of our nature; — for every discovery opens a new field for investigation of facts, shows us the imperfection of our theories. It has justly been said, that the greater the circle of light, the greater the boundary of darkness by which it is surrounded."

"Fortunately science, like that nature to which it belongs, is neither limited by time nor by space. It belongs to the world, and is of no country and of no age. The more we know, the more we feel our ignorance; the more we feel how much remains unknown; and in philosophy, the sentiment of the Macedonian hero can never apply, — there are always new worlds to conquer."

"Every new discovery may be considered as a new species of manufacture, awakening moral industry and sagacity, and employing, as it were, new capital of mind."

"That the forms of natural bodies may depend upon different arrangements of the same particles of matter has been a favourite hypothesis advanced in the earliest era of physical research, and often supported by the reasonings of the ablest philosophers. This sublime chemical speculation sanctioned by the authority of Hooke, Newton, and Boscovich, must not be confounded with the ideas advanced by the alchemists concerning the convertibility of the elements into each other. The possible transmutation of metals has generally been reasoned upon not as a philosophical research, but as an empirical process. Those who have asserted the actual production of the precious metals from other elements, or their decomposition, or who have defended the chimera of the philosopher's stone, have been either impostors, or men deluded by impostors. In this age of rational inquiry it will be useless to decry the practices of the adepts, or to caution the public against confounding the hypothetical views respecting the elements founded upon distinct analogies, with the dreams of alchemical visionaries, most of whom, as an author of the last century justly observed, professed an art without principles, the beginning of which was deceit, the progress delusion, and the end poverty."

"You write with great eloquence and truth on the effects of mountain scenery on the mind. Whatever exalts the imagination purifies the affections; but even our noblest and best thoughts have their archetypes in sensation. The eye is the most perfect of all the senses, and the one that most feeds the intellect. When surrounded by the grand forms of nature, we give to earth something of the indefinite character of heaven. Great objects excite great thoughts; the standard of our being rises; all our low and grovelling associations disappear; and our sympathies are more strongly awakened with regard to the moral, sublime, the excellent, the decorous, and the great in philosophy. We are more fitted to enjoy the blaze of light of Milton, to pass into the -forms of humanity with Shakespeare, and to move through the heavens with Newton. ... I am leading a truly philosophical life of activity, and the constant pursuit of an object, the elements of such a life. Such moments as I am now passing in the crowded city, prove to me how fitted our being is for independent and solitary thoughts; how much its strength depends upon its own efforts, and how little it owes to general society. Pray do not forget me, and believe me to be, very truly and affectionately, yours..."

"A small piece of pure ... was placed upon an insulated disk of platina, connected with the negative side of the battery... and a platina wire communicating with the positive side, was brought into contact with the... surface of the alkali. ...The potash began to fuse at both its points of electrization. There was a violent effervescence at the upper surface; at the lower, or negative, surface, there was no liberation of elastic fluid; but small globules, having a high metallic lustre, and being precisely similar in visible characters to quicksilver, appeared, some of which burnt with explosion and bright flame, as soon as they were formed, and others remained, and were merely tarnished, and finally covered with a white film which formed on their surfaces."

"A sacred spark created by his breath, The immortal mind of man his image bears; A spirit living 'midst the forms of death, Oppressed, but not subdued, by mortal cares."

"The moment after, I began to respire 20 quarts of unmingled nitrous oxide. A thrilling, extending from the chest to the extremities, was almost immediately produced. I felt a sense of tangible extension highly pleasurable in every limb; my visible impressions were dazzling, and apparently magnified, I heard distinctly every sound in the room and was perfectly aware of my situation. By degrees, as the pleasurable sensations increased, I last all connection with external things; trains of vivid visible images rapidly passed through my mind, and were connected with words in such a manner, as to produce perceptions perfectly novel. I existed in a world of newly connected and newly modified ideas. I theorised — I imagined that I made discoveries. When I was awakened from this semi-delirious trance by Dr. Kinglake, who took the bag from my mouth, indignation and pride were the first feelings produced by the sight of the persons about me. My emotions were enthusiastic and sublime; and for a minute I walked round the room, perfectly regardless of what was said to me. As I recovered my former state of mind, I felt an inclination to communicate the discoveries I had made during the experiment. I endeavoured to recall the ideas, they were feeble and indistinct; one collection of terms, however, presented itself: and with the most intense belief and prophetic manner, I exclaimed to Dr Kinglake, "Nothing exists but thoughts!—the universe is composed of impressions, ideas, pleasures and pains!""

"More and more of the flow was diverted from production into the political mechanism. Whatever elements in motion compose a stream of energy, enough must go through to complete the circuit and renew production. Water running in an aqueduct to turn a millwheel is a stream of energy; or electricity going through insulated wires; or goods in process from raw materials to finished product and conveyed by a system of transport. If the water channel is pierced with many small openings en route; or electricity taken off by more and more outlets; or the goods expropiated piecemeal at each stage of the process, finally not enough will go through for maintenance of the system. In the energy system comprised in an exchange of goods, the producers and processors have to get back enough to enable them to keep on producing and working up the raw materials and to provide transport..."

"Money is indispensable to a long-circuit heavy load energy system. It must be used when a sufficient surplus is being produced to allow a margin for exchange, and cost of transport, over a considerable distance. Money represents a storage battery when idle, and a generalized mode of the conversion of energy when it is in motion, with a function of equating time and space."

"An army is a diversion of energy from the productive life of a nation."

"In human affairs, all that endures is what men think."

"What the past shows, by overwhelming evidence, is that the imponderables outweigh every material article in the scales of human endeavor."

"Whoever is fortunate enough to be an American citizen came into the greatest inheritance man has ever enjoyed. He has had the benefit of every heroic and intellectual effort men have made for many thousands of years, realized at last. If Americans should now turn back, submit again to slavery, it would be a betrayal so base the human race might better perish."

"A tax-supported, compulsory educational system is the complete model of the totalitarian state."

"There can be no greater stretch of arbitrary power than is required to seize children from their parents, teach them whatever the authorities decree they shall be taught, and expropriate from the parents the funds to pay for the procedure."

"But when the good people do know, as they certainly do, that three million persons (at the least estimate) were starved to death in one year by the methods they approve, why do they still fraternize with the murderers and support the measures? Because they have been told that the lingering death of the three millions might ultimately benefit a greater number. The argument applies equally well to cannibalism."

"The philanthropist, the politician, and the pimp are inevitably found in alliance because they have the same motives, they seek the same ends, to exist for, through, and by others."

"The humanitarian in theory is the terrorist in action."

"But in reason if one man has no right to command all other men--the expedient of despotism--neither has he any right to command even one other man; nor yet have ten men, or a million, the right to command even one other man, for ten times nothing is nothing, and a million times nothing is nothing."

"The only way to prevent prostitution altogether would be to imprison one half of the human race."

"Whether it does any good or not, a law enforced must hurt someone."

"When the word leader, or leadership, returns to current use, it connotes a relapse into barbarism. For a civilized people, it is the most ominous word in any language."

"Men are born free, that since they begin with no government, they must therefore institute government by voluntary agreement, and thus government must be their agent, not their superior. Since volition is a function of the individual, the individual has the precedent right. Then even if it was presumed that government did equate roughly with the moral shorcomings of humanity, it should still be limited and subsidiary. If everyone were invariably honest, able, wise, and kind, there should be no occasion for government. Everyone would readily understand what is desirable and what is possible in given circumstances, all would concur upon the best means toward their purpose and for equitable participation in the ensuing benefits, and would act without compulsion or default. The maximum production was certainly obtained from such voluntary action arising from personal initiative. But since human beings will sometimes lie, shirk, break promises, fail to improve their faculties, act imprudently, seize by violence the goods of others, and even kill one another in anger or greed, the government might be defined as the police organization. In that case, it must be described as a necessary evil. It would have no existence as a separate entity, and no intrinsic authority; it could not be justly empowered to act excepting as individuals infringed one another's rights, when it should enforce prescribed penalties. Generally, it would stand in the relation of a witness to contract, holding a forfeit for the parties. As such, the least practicable measure of government must be the best. Anything beyond the minimum must be oppression."

"These are not sentimental considerations; they constitute the mechanism of production and therefore of power. Personal liberty is the pre-condition of the release of energy. Private property is the inductor which initiates the flow. Real money is the transmission line; and the payment of debts comprises half the circuit. An empire is merely a long circuit energy-system. The possibility of a short circuit, ensuing leakage and breakdown or explosion, occurs in the hook-up of political organization to the productive processes. This is not a figure of speech or analogy, but a specific physical description of what happens."

"All these efforts in the search for truth tend to lead it [the human mind] back continually to the vast intelligence... but from which it will always remain infinitely removed. This tendency peculiar to the human race is that which renders it superior... and their progress in this respect distinguishes nations and ages and constitutes their true glory."

"Given for one instant an intelligence which could comprehend all the forces by which nature is animated and the respective situation of the beings who compose it—an intelligence sufficiently vast to submit these data to analysis—it would embrace in the same formula the movements of the greatest bodies of the universe and those of the lightest atom; for it, nothing would be uncertain and the future, as the past, would be present to its eyes. The human mind offers, in the perfection which it has been able to give to astronomy, a feeble idea of this intelligence. Its discoveries in mechanics and geometry, added to that of universal gravity, have enabled it to comprehend in the same analytical expressions the past and future states of the system of the world."

"Imaginary causes have gradually receded with the widening bounds of knowledge and disappear entirely before sound philosophy, which sees in them only the expression of our ignorance of the true causes."

"The most important questions of life... are indeed for the most part only problems of probability. Strictly speaking it may even be said that nearly all our knowledge is problematical; and in the small number of things which we are able to know with certainty, even in the mathematical sciences themselves, the principal means for ascertaining truth—induction and analogy—are based on probabilities."

"On demandait à Laplace quel était selon lui le plus grand mathématicien de l'Allemagne. C'est Pfaff, répondit-il. - Je croyais, reprit l'interlocuteur, que Gauss lui était supérieur. - Mais, s'écria Laplace, vous me demandez quel est le plus grand mathématicien de l'Allemagne, et Gauss est le plus grand mathématicien de l'Europe."

"It is India that gave us the ingenious method of expressing all numbers by means of ten symbols, each symbol receiving a value of position as well as an absolute value; a profound and important idea which appears so simple to us now that we ignore its true merit.But its very simplicity and the great ease which it has lent to computations put our arithmetic in the first rank of useful inventions; and we shall appreciate the grandeur of the achievement the more when we remember that it escaped the genius of Archimedes and Apollonius, two of the greatest men produced by antiquity."
