Quotes about doubt (2565 quotes, page 12)

“… mathematicians progress only by doubt, through humble and constant attempts to impinge on the immense domain of the unknown.”

“The dominant system of power in the west has been Platonist — a system which functions on highly developed levels of structure and law. This is the school of pure rationality and fear of the undefined — fear of doubt. The minority system has been Socratic or humanist. It is interested in doubt and not overwhelmed by the Platonist-Hobbesian desperate need to tie things down.”

“There's no doubt that my forehand and backhand can match anyone, it's about the place that they're put in. I can hit the ball as hard as anyone can, but I think it's more about where I'm hitting the ball. Instead of 90 mph it can just be a 50 mph forehand, but the placement is more important. So I've been working on that a lot more. When you're working on things, maybe your performance drops a little bit or you're trying new things in every tournament you're going in so that's just a process of being an athlete because you're learning, you're adding new things to your game. When I sit with my notes, for instance, instead of hitting a hard forehand return, I would like to hit an angled forehand return instead.”

“What are the great faults of conversation? Want of ideas, want of words, want of manners, are the principal ones, I suppose you think. I don't doubt it, but I will tell you what I have found spoil more good talks than anything else;—long arguments on special points between people who differ on the fundamental principles upon which these points depend. No men can have satisfactory relations with each other until they have agreed on certain ultimata [finalities] of belief not to be disturbed in ordinary conversation, and unless they have sense enough to trace the secondary questions depending upon these ultimate beliefs to their source. In short, just as a written constitution is essential to the best social order, so a code of finalities is a necessary condition of profitable talk between two persons.”

“Muslim historians credit all their heroes with many expeditions each of which “laid waste” this or that province or region or city or countryside. The foremost heroes of the imperial line at Delhi and Agra such as Qutbu’d-Dîn Aibak (1192-1210 A. D.), Shamsu’d-Dîn Iltutmish (1210-36 A. D.), Ghiyãsu’d-Dîn Balban (1246-66 A D.), Alãu’d-Dîn Khaljî (1296-1316 A. D.), Muhammad bin Tughlaq (1325-51 A. D.), Fîruz Shãh Tughlaq (135188 A. D.) Sikandar Lodî (1489-1519 A. D.), Bãbar (1519-26 A. D.) and Aurangzeb (1658-1707 A. D.) have been specially hailed for “hunting the peasantry like wild beasts”, or for seeing to it that “no lamp is lighted for hundreds of miles”, or for “destroying the dens of idolatry and God-pluralism” wherever their writ ran. The sultans of the provincial Muslim dynasties-Malwa, Gujarat, Sindh, Deccan, Jaunpur, Bengal-were not far behind, if not ahead, of what the imperial pioneers had done or were doing; quite often their performance put the imperial pioneers to shame. No study has yet been made of how much the human population declined due to repeated genocides committed by the swordsmen of Islam. But the count of cities and towns and villages which simply disappeared during the Muslim rule leaves little doubt that the loss of life suffered by the cradle of Hindu culture was colossal.”

“An-Nu'man ibn Bashir said, "I heard the Messenger of Allah, may Allah bless him and grant him peace, say, "The halal is clear and the haram is clear. But between the two there are doubtful things about which most people have no knowledge. Whoever exercises caution with regard to what is doubtful, shows prudence in respect of his deen and his honour. Whoever gets involved in the doubtful things is like a herdsman who grazes his animals near a private preserve (hima). He is bound to enter it. Every king has a private preserve and the private preserve of Allah on His earth are the things that He has made forbidden. There is lump of flesh in the body, the nature of which is that when it is sound, the entire body is sound, and when it is corrupt, the entire body is corrupt - it is the heart."”

“Peace has an economic foundation to which too little attention has been given. No student can doubt that it was to a large extent the economic condition of Europe that drove those overburdened countries headlong into the World War. They were engaged in maintaining competitive armaments. If one country laid the keel of one warship, some other country considered it necessary to lay the keel of two warships. If one country enrolled a regiment, some other country enrolled three regiments. Whole peoples were armed and drilled and trained to the detriment of their industrial life, and charged and taxed and assessed until the burden could no longer be borne. Nations cracked under the load and sought relief from the intolerable pressure by pillaging each other. It was to avoid a repetition of such a catastrophe that our Government proposed and brought to a successful conclusion the Washing- ton Conference for the Limitation of Naval Armaments. We have been altogether desirous of an extension of this principle and for that purpose have sent our delegates to a preliminary conference of nations now sitting at Geneva. Out of that conference we expect some practical results. We believe that other nations ought to join with us in laying aside their suspicions and hatreds sufficiently to agree among themselves upon methods of mutual relief from the necessity of the maintenance of great land and sea forces. This can not be done if we constantly have in mind the resort to war for the redress of wrongs and the enforcement of rights. Europe has the League of Nations. That ought to be able to provide those countries with certain political guaranties which our country does not require. Besides this there is the World Court, which can certainly be used for the determination of all justifiable disputes. We should not underestimate the difficulties of European nations, nor fail to extend to them the highest degree of patience and the most sympathetic consideration. But we can not fail to assert our conviction that they are in great need of further limitation of armaments and our determination to lend them every assistance in the solution of their problems. We have entered the conference with the utmost good faith on our part and in the sincere belief that it represents the utmost good faith on their part. We want to see the problems that are there presented stripped of all technicalities and met and solved in a way that will secure practical results. We stand ready to give our support to every effort that is made in that direction.”

“Now this structure of hope (among other things) is also what distinguishes philosophy from the special sciences. There is a relationship with the object that is different in principle in the two cases. The question of the special sciences is in principle ultimately answerable, or, at least, it is not un-answerable. It can be said, in a final way (or some day, one will be able to say in a final way) what is the cause, say, of this particular infectious disease. It is in principle possible that one day someone will say, "It is now scientifically proven that such and such is the case, and no otherwise." But […] a philosophical question can never be finally, conclusively answered. […] The object of philosophy is given to the philosopher on the basis of a hope. This is where Dilthey's words make sense: "The demands on the philosophizing person cannot be satisfied. A physicist is an agreeable entity, useful for himself and others; a philosopher, like the saint, only exists as an ideal." It is in the nature of the special sciences to emerge from a state of wonder to the extent that they reach "results." But the philosopher does not emerge from wonder.
Here is at once the limit and the measure of science, as well as the great value, and great doubtfulness, of philosophy. Certainly, in itself it is a "greater" thing to dwell "under the stars."”

Josef Pieper (1904–1997) German philosopher

But man is not made to live "out there" permanently! Certainly, it is a more valuable question, as such, to ask about the whole world and the ultimate nature of things. But the answer is not as easily forthcoming as for the special sciences!

“An eternal purgatory, then, rather than a heaven of glory; an eternal ascent. If there is an end to all suffering, however pure and spiritualized we may suppose it to be, if there is an end to all desire, what is it that makes the blessed in paradise go on living? If in paradise they do not suffer for want of God, how shall they love Him? And if there, in the heaven of glory, while they behold God little by little and closer and closer, yet without ever wholly attaining Him, there does not always remain something more for them to know and desire, if there does not always remain a substratum of doubt, how shall they not fall asleep?”

“Without doubt, the reason for increasing demands on the Federal Government is that the States have not discharged their full duties. Some have done better and some worse, but as a whole they have not done all they should. So demand has grown up for a greater concentration of powers in the Federal Government. If we will fairly consider it, we must conclude that the remedy would be worse than the disease. What we need is not more Federal government but better local government. Yet many people who would agree to this have large responsibility for the lapses of local authority.”

“There can indeed be little doubt that for nearly two hundred years after its establishment in Europe, the Christian community exhibited a moral purity which, if it has been equaled, has never for any long period been surpassed. Completely separated from the Roman world that was around them, abstaining alike from political life, from appeals to the tribunals, and from military occupations; looking forward continually to the immediate advent of their Master, and the destruction of the Empire in which they dwelt, and animated by all the fervor of a young religion, the Christiana found within themselves a whole order of ideas and feelings sufficiently powerful to guard them from the contamination of their age.”

Wherever the deductions of political economy lead I am prepared to follow. By the way, have you had time to read Bastiat's partly posthumous volume, 'Les Harmonies Economiques'?

“To be identified with the public is the divine gift of the best-sellers in popular Romance and, no doubt, in popular realism. E. M.

“There is little doubt that the observation that quality may depend on price (productivity on wages; default probability on interest rates) has provided a rich mine for economic theorists: A simple modification of the basic assumptions results in a profound alteration of many of the basic conclusions of the standard paradigm. The Law of Supply and Demand has been repealed. The Law of the Single Price has been repealed. The Fundamental Theorem of Welfare Economics has been shown not to be valid.
More than that, the theories that we describe here provide the basis of progress toward a unification of macroeconomics and microeconomics. They pro vide an explanation of unemployment and credit rationing, derived from basic microeconomic principles. It is a theory in which the extensive idleness that periodically confronts society's resources, human and capital, is seen as but the most obvious example of market failures that prevasively and persistently distort the allocation of resources.”

“No doubt analytical psychologists could tear it all to bits and explain it in the jargon of this or that psychological school. Critics could trample on my dreams and say that it was too much in the realm of feeling to have any value, but so is falling in love. Is that not real, and highly significant, and life-changing? So is the state of mind induced by music, or by some of the glories of Nature, or by some of the works of man... All I can say is that to me it was an experience of God, never to be denied... No one who has had such an experience can ever doubt but that in the end good will triumph over every form of evil, and that every life, however humble, frustrated, indifferent or even careless, is in the care of this Power and within a Plan, vast beyond our power to imagine, which will work out in a blessedness which brings utter satisfaction and quality of bliss for which there are no words.”

“Dr. Kallen says, "Free public education and private instruction purchasable at a price are both but the community's device to meet present needs by transmitting the past unchanged. They provide a grammar of assent, not a logic of inquiry. The mental posture they habituate the youth in is not the posture of reflection. The mental posture they habituate the youth in is the posture of conformity. They require belief, not investigation. They impose reverence for the past and idealization of the present. They envision the future as a perpetuation of the past, not as a new creation of it. They are Main Street's most powerful instrument of self-reproduction without variation…. They enable government both visible and invisible to continue by consent, for they forestall and inhibit in the citizens of the land the technique of doubt and dissent which is the necessary condition of good government and the true inward-ness of that eternal vigilance so notoriously the price of liberty."”

“He fixed his definition thus: reflection is the possibility of the relation, consciousness is the relation, the first form of which is contradiction. He soon noted that, as a result, the categories of reflection are always dichotomous. For example ideality and reality, soul and body, to recognize – the true, to will – the good, to love – the beautiful, God and the world, and so on, these are categories of reflection. In reflection, these touch each other in such a way that a relation becomes possible. The categories of consciousness, on the other hand, are trichotomous, as language itself indicates, for when I say I am conscious of this, I mention a trinity. Consciousness is mind and spirit, and the remarkable thing is that when in the world of mind or spirit one is divided, it always becomes three and never two. Consciousness, therefore, presupposes reflection. If this were not true it would be impossible to explain doubt. True, language seems to contest this, since in most languages, as far as he knew, the word ‘doubt’ is etymologically related to the word ‘two’. Yet in his opinion this only indicated the presupposition of doubt, especially because it was clear to him that as soon as I, as spirit, become two, I am eo ipso three. If there were nothing but dichotomies, doubt would not exist, for the possibility of doubt lies precisely in that third which places the two in relation to each other. One cannot therefore say that reflection produces doubt, unless one expressed oneself backwards; one must say that doubt presupposes reflection, though not in a temporal sense. Doubt arises through a relation between two, but for this to take place the two must exist, although doubt, as a higher expression, comes before rather than afterwards.”

“The size of a firm influences its competitive policies in a number of ways. In the first place the scale of its purchases and sales relative to the total volume of transactions in the firm's market is one indication of the extent of its market control. Taken in conjunction with other data it may throw a good deal of light on price and production policies. Certain authorities, on the other hand, brush aside figures on the relative size of firms as irrelevant and emphasize the decisive importance of the elasticity of the firm's demand curve. 3 It would no doubt be extremely convenient if economists knew the shape of individual demand and cost curves and could proceed forthwith, by comparisons of price and marginal cost, to conclusions regarding the existing degree of monopoly power. The extent to which the monopoly theorists, however, refrain from an empirical application of their formulae is rather striking.”

I'm convinced Noah would have had the intelligence necessary to devise methods of feeding and caring [for the animals on the ark] that would put today's farmer's to shame. If farmers today have methods that could easily allow eight people to look after 16,000 animals - I've no doubt Noah could do much more!”

Mr. Juozapaitis has a full baritone that displays nice range and clarity, and coupled with the ease with which he commanded the stage, provided just the right measure of appeal that communicated to the audience the conflict and suppressed rage the character, no doubt, felt toward those who used and mocked him.

“He fell behind his brothers two or three inches in height, and proportionally in bone and weight. His character and processes of mind seemed to share in this fining-down process of scale. He was not good in a fight, and his nerves were more delicate than boys' nerves ought to be. He exaggerated these weaknesses as he grew older. The habit of doubt; of distrusting his own judgment and of totally rejecting the judgment of the world; the tendency to regard every question as open; the hesitation to act except as a choice of evils; the shirking of responsibility; the love of line, form, quality; the horror of ennui; the passion for companionship and the antipathy to society — all these are well-known qualities of New England character in no way peculiar to individuals but in this instance they seemed to be stimulated by the fever, and Henry Adams could never make up his mind whether, on the whole, the change of character was morbid or healthy, good or bad for his purpose. His brothers were the type; he was the variation.”

All our heavy cannon on garrison carriages, and heavy and superfluous stores of every kind, are removed to the main, and to the north end of the Island, where we intend to intrench and attempt to hold it, and wait the chance of events. General Hancock is gone to Boston to forward the repairs of the fleet, and to prepare the mind of the Count for a speedy return. How far he will succeed, I cannot pretend to say. I think it a matter of some doubt yet, whether the enemy will reenforce, or take off this garrison. If they expect a superior fleet from Europe, they will reenforce; but, if not, they will remove the garrison.”

“The difficulties which Arkwright encountered in organizing his factory system, were much greater than is commonly imagined. In the first place, he had to train his work-people to a precision in assiduity altogether unknown before, against which their listless and restive habits rose in continual rebellion; in the second place, he had to form a body of accurate mechanics, very different from the rude hands which then satisfied the manufacturer; in the third, he had to seek a market for his yarns; and in the fourth, he had to resist competition in its most odious forms. From the concurrence of these circumstances, we find that so late as the year 1779, ten years after the date of his first patent, his enterprise was regarded by many as a doubtful novelty.”

“There are four causes of infidelity and loss of belief in Allah: hankering after whims, a passion to dispute every argument, deviation from truth; and dissension, because whoever hankers after whims does not incline towards truth; whoever keeps on disputing every argument on account of his ignorance, will always remain blind to truth, whoever deviates from truth because of ignorance, will always take good for evil and evil for good and he will always remain intoxicated with misguidance. And whoever makes a breach (with Allah and His Messenger) his path becomes difficult, his affairs will become complicated and his way to salvation will be uncertain.
Similarly, doubt has also four aspects absurd reasoning; fear; vacillation and hesitation; and unreasonable surrender to infidelity, because one who has accustomed himself to unreasonable and absurd discussions will never see the Light of Truth and will always live in the darkness of ignorance. One who is afraid to face facts (of life, death and the life after death) will always turn away from ultimate reality, one who allows doubts and uncertainties to vacillate him will always be under the control of Satan and one who surrenders himself to infidelity accepts damnation in both the worlds.”

Instead, they devote themselves to protecting their “personal honor” against insults; and conversely they dream of the transient notoriety which will prove that they are “somebody,” which they doubt. The personal honor that they protect does not include truthfulness, honesty, public usefulness, integrity, independence, or virtues like that. A reputation for these things does not win respect, it has no publicity value; it’s believed to be phony anyway, and if it’s true, the person is hard to get along with.”

“There is one feature I notice that is generally missing in cargo cult science. … It's a kind of scientific integrity, a principle of scientific thought that corresponds to a kind of utter honesty — a kind of leaning over backwards. For example, if you're doing an experiment, you should report everything that you think might make it invalid — not only what you think is right about it; other causes that could possibly explain your results; and things you thought of that you've eliminated by some other experiment, and how they worked — to make sure the other fellow can tell they have been eliminated. Details that could throw doubt on your interpretation must be given, if you know them. You must do the best you can — if you know anything at all wrong, or possibly wrong — to explain it. If you make a theory, for example, and advertise it, or put it out, then you must also put down all the facts that disagree with it, as well as those that agree with it. There is also a more subtle problem. When you have put a lot of ideas together to make an elaborate theory, you want to make sure, when explaining what it fits, that those things it fits are not just the things that gave you the idea for the theory; but that the finished theory makes something else come out right, in addition. In summary, the idea is to try to give all of the information to help others to judge the value of your contribution; not just the information that leads to judgement in one particular direction or another.”

Furthermore it is possible in this way to render timber and other such materials non-inflammable and rot resistant; to produce drinking and spa-water for man, beast and soil of any desired composition and performance artificially, but in the way that it occurs in Nature; to raise water in a vertical pipe without pumping devices; to produce any amount of electricity and radiant energy almost without cost; to raise soil quality and to heal cancer, tuberculosis and a variety of nervous disorders… the practical implementation of this … would without doubt signify a complete reorientation in all areas of science and technology.

“The issue of 'science' does not intrude itself directly upon the occasion of the performance of a musical work, at least a non-electronically produced work, since—as has been said—there is at least a question as to whether the question as to whether musical composition is to be regarded as a science or not is indeed really a question; but there is no doubt that the question as to whether musical discourse or—more precisely—the theory of music should be subject to the methodological criteria of scientific method and the attendant scientific language is a question, except that the question is really not the normative one of whether it 'should be' or 'must be,' but the factual one that it is, not because of the nature of musical theory, but because of the nature and scope of scientific method and language, whose domain of application is such that if it is not extensible to musical theory, then musical theory is not a theory in any sense in which the term ever has been employed.

Some parents have entirely prohibited their children from tasting intoxicating liquors; but a parent’s authority cannot last for ever; children are naturally prone to hanker after forbidden things; and a child, in such a case, would be likely to have a strong curiosity to taste, and try the effect of what has been so lauded and enjoyed by others, so strictly forbidden to himself – which curiosity would generally be gratified on the first convenient opportunity; and the restraint once broken, serious consequences might ensue.”

“History knew a midnight, which we may estimate at about the year 1000 A. D., when the human race lost the arts and sciences even to the memory. The last twilight of paganism was gone, and yet the new day had not begun. Whatever was left of culture in the world was found only in the Saracens, and a Pope eager to learn studied in disguise in their unversities, and so became the wonder of the West. At last Christendom, tired of praying to the dead bones of the martyrs, flocked to the tomb of the Saviour Himself, only to find for a second time that the grave was empty and that Christ was risen from the dead. Then mankind too rose from the dead. It returned to the activities and the business of life; there was a feverish revival in the arts and in the crafts. The cities flourished, a new citizenry was founded. Cimabue rediscovered the extinct art of painting; Dante, that of poetry. Then it was, also, that great courageous spirits like Abelard and Saint Thomas Aquinas dared to introduce into Catholicism the concepts of Aristotelian logic, and thus founded scholastic philosophy. But when the Church took the sciences under her wing, she demanded that the forms in which they moved be subjected to the same unconditioned faith in authority as were her own laws. And so it happened that scholasticism, far from freeing the human spirit, enchained it for many centuries to come, until the very possibility of free scientific research came to be doubted. At last, however, here too daylight broke, and mankind, reassured, determined to take advantage of its gifts and to create a knowledge of nature based on independent thought. The dawn of the day in history is know as the Renaissance or the Revival of Learning.”

“They reckon ill who leave me out;
When me they fly, I am the wings;
I am the doubter and the doubt;
And I the hymn the Brahmin sings.”

“There is an eloquence in true enthusiasm that is not to be doubted.”

Washington Irving (1783–1859) writer, historian and diplomat from the United States

"The Adventure Of The German Student".

“June 7, 1776, Richard Henry Lee, on behalf of the Virginia delegation, submitted to the Continental Congress three resolutions, of which the first declared that "these United Colonies are, and of right ought to be, free and independent States, that they are absolved from all allegiance to the British Crown, and that all political connection between them and the State of Great Britain is, and ought to be, totally dissolved. This resolution, which may conveniently be called the Resolution of Independence, was finally voted by the Continental Congress on the 2 of July, 1776. Strictly speaking, this was the official declaration of independence; and if we were a nation of antiquaries we should no doubt find an incongruity in celebrating the anniversary of our independence on the 4 of July.”

“He who doubts from what he sees
Will ne'er believe, do what you please.
If the sun and moon should doubt
They'd immediately go out.”

“There's no doubt in my mind that going vegetarian has made me feel better not only physically, but also because I learned about the suffering of animals who are raised and killed for food. I feel good knowing that I'm not contributing to that.”

“The great break in the organic chain between man and his nearest allies, which cannot be bridged over by any extinct or living species, has often been advanced as a grave objection to the belief that man is descended from some lower form; but this objection will not appear of much weight to those who, convinced by general reasons, believe in the general principle of evolution. Breaks incessantly occur in all parts of the series, some being wide, sharp and defined, others less so in various degrees; as between the orang and its nearest allies—between the Tarsius and the other Lemuridæ—between the elephant and in a more striking manner between the Ornithorhynchus or Echidna, and other mammals. But all these breaks depend merely on the number of related forms which have become extinct. At some future period, not very distant as measured by centuries, the civilised races of man will almost certainly exterminate and replace throughout the world the savage races. At the same time the anthropomorphous apes, as Professor Schaaffhausen has remarked, will no doubt be exterminated. The break will then be rendered wider, for it will intervene between man in a more civilised state, as we may hope, than the Caucasian, and some ape as low as a baboon, instead of as at present between the negro or Australian and the gorilla.”

Charles Darwin book The Descent of Man, and Selection in Relation to Sex

The sentence "At some future period … the savage races" is often quoted out of context to suggest that Darwin desired this outcome, whereas in fact Darwin simply held that it would occur.
