Quotes about speculation

“It's cold, it's always cold in the sanatorium; which leads me to speculate that, maybe, and just maybe, it's not a simple coincidence.”

“Now the kind of philosophy under which we proceed in the whole and in the part is moral philosophy or ethics; because the whole was undertaken not for speculation but for practice.”
Genus vero philosophie, sub quo hic in toto et parte proceditur, est morale negotium, sive ethica; quia non ad speculandum, sed ad opus inventum est totum et pars.

Dante Alighieri (1265–1321) Italian poet

“This whole Jewish world, comprising a single exploiting sect, a kind of blood sucking people, a kind of organic destructive collective parasite, going beyond not only the frontiers of states, but of political opinion, this world is now, at least for the most part, at the disposal of Marx on the one hand, and of Rothschild on the other… This may seem strange. What can there be in common between socialism and a leading bank? The point is that authoritarian socialism, Marxist communism, demands a strong centralisation of the state. And where there is centralisation of the state, there must necessarily be a central bank, and where such a bank exists, the parasitic Jewish nation, speculating with the Labour of the people, will be found.”

Mikhail Bakunin (1814–1876) Russian revolutionary, philosopher, and theorist of collectivist anarchism

“If the development by the enemy as well as by us of thermonuclear weapons could have been averted, I think we would be in a somewhat safer world today than we are…I do not think we want to argue technical questions here, and I do not think it is very meaningful for me to speculate as to how we would have responded had the technical picture at that time been more as it was later.
However, it is my judgment in these things that when you see something that is technically sweet, you go ahead and do it and you argue about what to do about it only after you have had your technical success. That is the way it was with the atomic bomb. I do not think anybody opposed making it; there were some debates about what to do with it after it was made. I cannot very well imagine if we had known in late 1949 what we got to know by early 1951 that the tone of our report would have been the same.”

“Exchange unprofitable religious speculations for actual God-contact. Clear your mind of dogmatic theological debris; let in the fresh, healing waters of direct perception.”

Lahiri Mahasaya (1828–1895) Indian yogi and guru

Clear your mind of dogmatic theological debris; let in the fresh, healing waters of direct perception. Attune yourself to the active inner Guidance; the Divine Voice has the answer to every dilemma of life. Though man's ingenuity for getting himself into trouble appears to be endless, the Infinite Succor is no less resourceful.

“So we find that the three possible solutions of the great problem of increasing human energy are answered by the three words: food, peace, work. Many a year I have thought and pondered, lost myself in speculations and theories, considering man as a mass moved by a force, viewing his inexplicable movement in the light of a mechanical one, and applying the simple principles of mechanics to the analysis of the same until I arrived at these solutions, only to realize that they were taught to me in my early childhood. These three words sound the key-notes of the Christian religion. Their scientific meaning and purpose now clear to me: food to increase the mass, peace to diminish the retarding force, and work to increase the force accelerating human movement. These are the only three solutions which are possible of that great problem, and all of them have one object, one end, namely, to increase human energy. When we recognize this, we cannot help wondering how profoundly wise and scientific and how immensely practical the Christian religion is, and in what a marked contrast it stands in this respect to other religions. It is unmistakably the result of practical experiment and scientific observation which have extended through the ages, while other religions seem to be the outcome of merely abstract reasoning. Work, untiring effort, useful and accumulative, with periods of rest and recuperation aiming at higher efficiency, is its chief and ever-recurring command. Thus we are inspired both by Christianity and Science to do our utmost toward increasing the performance of mankind. This most important of human problems I shall now specifically consider.”

“Of course it's tempting to close one's eyes to history, and instead speculate about the roots of war in some possible animal instinct: as if, like the tiger, we still had to kill to live, or, like the robin redbreast, to defend a nesting territory. But war, organized war, is not a human instinct. It is a highly planned and cooperative form of theft. And that form of theft began 10,000 years ago when the harvesters of wheat accumulated a surplus and the nomads rose out of the desert to rob them of what they themselves could not provide. The evidence for that, we saw, in the walled city of Jericho and its prehistoric tower… That is the beginning of war.”

“It seems to me that men of coarse and clumsy habits and of small knowledge do not deserve such fine instruments nor so great a variety of natural mechanism as men of speculation and of great knowledge; but merely a sack in which their food may be stowed and whence it may issue, since they cannot be judged to be any thing else than vehicles for food; for it seems to me they have nothing about them of the human species but the voice and the figure, and for all the rest are much below beasts.”

“As all our knowledge of the material world is derived from the information of our senses, natural philosophers have, in modern times, wisely abandoned to metaphysicians, all speculations concerning the nature of that substance of which it is composed; concerning the possibility or impossibility of its being created; concerning the efficient causes of the changes which take place in it; and even concerning the reality of its existence, independent of that of percipient beings: and have confined themselves to the humbler province of observing the phenomena it exhibits, and of ascertaining their general laws.”

“The Common Sense, is that which judges of things offered to it by the other senses. The ancient speculators have concluded that that part of man which constitutes his judgment is caused by a central organ to which the other five senses refer everything by means of impressibility; and to this centre they have given the name Common Sense. And they say that this Sense is situated in the centre of the head between Sensation and Memory. And this name of Common Sense is given to it solely because it is the common judge of all the other five senses i. e. Seeing, Hearing, Touch, Taste and Smell. This Common Sense is acted upon by means of Sensation which is placed as a medium between it and the senses. Sensation is acted upon by means of the images of things presented to it by the external instruments, that is to say the senses which are the medium between external things and Sensation. In the same way the senses are acted upon by objects. Surrounding things transmit their images to the senses and the senses transfer them to the Sensation. Sensation sends them to the Common Sense, and by it they are stamped upon the memory and are there more or less retained according to the importance or force of the impression.”

“The generality of men are so bound within the sphere of their circumstances that they have not even the courage to get out of them through their ideas, and if we see a few whom, in a way, speculation over great things makes incapable of mean ones, we find still more with whom the practice of small things takes away the feeling for great ones.”

“I have sometimes amused myself by endeavouring to fancy what would be the fate of an individual gifted, or rather accursed, with an intellect very far superior to that of his race. Of course he would be conscious of his superiority; nor could he (if otherwise constituted as man is) help manifesting his consciousness. Thus he would make himself enemies at all points. And since his opinions and speculations would widely differ from those of all mankind — that he would be considered a madman is evident. How horribly painful such a condition! Hell could invent no greater torture than that of being charged with abnormal weakness on account of being abnormally strong.In like manner, nothing can be clearer than that a very generous spirit — truly feeling what all merely profess — must inevitably find itself misconceived in every direction — its motives misinterpreted. Just as extremeness of intelligence would be thought fatuity, so excess of chivalry could not fail of being looked upon as meanness in the last degree — and so on with other virtues. This subject is a painful one indeed. That individuals have so soared above the plane of their race is scarcely to be questioned; but, in looking back through history for traces of their existence, we should pass over all the biographies of the "good and the great," while we search carefully the slight records of wretches who died in prison, in Bedlam, or upon the gallows.”

“All classes, therefore, must be brought under women’s influence; for all require to be reminded constantly of the great truth that Reason and Activity are subordinate to Feeling. Of their influence upon philosophers I have spoken. If they are men worthy of their mission, they will be conscious of the tendency which their life has to harden them and lead them into useless speculation; and they will feel the need of renewing the ardour of their social sympathy at its native source. Feeling, when it is pure and deep, corrects its own errors, because they clash with the good to which it is ever tending. But erroneous use of the intellectual or practical faculties, cannot be even recognized, much less corrected, without the aid of Affection, which is the only part of our nature that suffers directly from such errors. Therefore whenever either the philosopher or the people deviate from duty, it will be the part of women to remonstrate with them gently, and recall them to the true social principles which are entrusted to their special charge.”

“Philosophy is to be studied, not for the sake of any definite answers to its questions, since no definite answers can, as a rule, be known to be true, but rather for the sake of the questions themselves; because these questions enlarge our conception of what is possible, enrich our intellectual imagination and diminish the dogmatic assurance which closes the mind against speculation; but above all because, through the greatness of the universe which philosophy contemplates, the mind is also rendered great, and becomes capable of that union with the universe which constitutes its highest good.”

“What may be the fate of the Eastern part of Europe it would be arrogant for me to speculate upon…But I am sure that as long as England is ruled by English Parties who understand the principles on which our Empire is founded, and who are resolved to maintain that Empire, our influence in that part of the world can never be looked upon with indifference…The present is a state of affairs which requires the most vigilant examination and the most careful management. But those who suppose that England ever would uphold, or at this moment particularly is upholding, Turkey from blind superstition and from a want of sympathy with the highest aspirations of humanity are deceived. What our duty is at this critical moment is to maintain the Empire of England. Nor will we ever agree to any step, though it may obtain for a moment comparative quiet and a false prosperity, that hazards the existence of that Empire.”

“Economic powers continue to justify the current global system where priority tends to be given to speculation and the pursuit of financial gain, which fail to take the context into account, let alone the effects on human dignity and the natural environment. Here we see how environmental deterioration and human and ethical degradation are closely linked. Many people will deny doing anything wrong because distractions constantly dull our consciousness of just how limited and finite our world really is.”

“While the earnings of a minority are growing exponentially, so too is the gap separating the majority from the prosperity enjoyed by those happy few. This imbalance is the result of ideologies which defend the absolute autonomy of the marketplace and financial speculation. Consequently, they reject the right of states, charged with vigilance for the common good, to exercise any form of control. A new tyranny is thus born, invisible and often virtual, which unilaterally and relentlessly imposes its own laws and rules. Debt and the accumulation of interest also make it difficult for countries to realize the potential of their own economies and keep citizens from enjoying their real purchasing power. To all this we can add widespread corruption and self-serving tax evasion, which have taken on worldwide dimensions. The thirst for power and possessions knows no limits. In this system, which tends to devour everything which stands in the way of increased profits, whatever is fragile, like the environment, is defenseless before the interests of a deified market, which become the only rule.”

“Oh! human stupidity, do you not perceive that, though you have been with yourself all your life, you are not yet aware of the thing you possess most of, that is of your folly? and then, with the crowd of sophists, you deceive yourselves and others, despising the mathematical sciences, in which truth dwells and the knowledge of the things included in them. And then you occupy yourself with miracles, and write that you possess information of those things of which the human mind is incapable and which cannot be proved by any instance from nature. And you fancy you have wrought miracles when you spoil a work of some speculative mind, and do not perceive that you are falling into the same error as that of a man who strips a tree of the ornament of its branches covered with leaves mingled with the scented blossoms or fruit.”

“The Ellipse is the most simple of the Conic Sections, most known, and nearest of Kin to a Circle, and easiest describ'd by the Hand in plano. Though many prefer the Parabola before it, for the Simplicity of the Æquation by which it is express'd. But by this Reason the Parabola ought to be preferr'd before the Circle it self, which it never is. Therefore the reasoning from the Simplicity of the Æquation will not hold.

“If you condemn painting, which is the only imitator of all visible works of nature, you will certainly despise a subtle invention which brings philosophy and subtle speculation to the consideration of the nature of all forms — seas and plains, trees, animals, plants and flowers — which are surrounded by shade and light. And this is true knowledge and the legitimate issue of nature; for painting is born of nature — or, to speak more correctly, we will say it is the grandchild of nature; for all visible things are produced by nature, and these her children have given birth to painting. Hence we may justly call it the grandchild of nature and related to God.”

“In all these papers we see a love of honest work, an aversion to shams, a caution in the enunciation of conclusions, a distrust of rash generalizations and speculations based on uncertain premises. He was never anxious to add one more guess on doubtful matters in the hope of hitting the truth, or what might pass as such for a time, but was always ready to take infinite pains in the most careful testing of every theory. With these qualities was united a modesty which forbade the pushing of his own claims and desired no reputation except the unsought tribute of competent judges.”

“When we believe that science or religion "has the truth," we stop our speculations. While still referring to the theory of evolution, science accepts it as a fact, about existence, and therefore any speculation that threatens that theory becomes almost heretical.”

Context: When we believe that science or religion "has the truth," we stop our speculations. While still referring to the theory of evolution, science accepts it as a fact, about existence, and therefore any speculation that threatens that theory becomes almost heretical. So often it seems that there is no other choice in the matter of man's origin than a meaningless universe and an earth populated by creatures who fight for survival, or a universe created by Christianity's objectified God.

Bridges, The 'Opus Majus' of Roger Bacon (1900) Vol.1 http://books.google.com/books?id=6F0XAQAAMAAJ Preface pp.x-xi Context: All these foregoing sciences are, properly speaking, speculative. There is indeed in every science a practical side, as Avicenna teaches in the first book of his Art of Medicine. Nevertheless, of Moral Philosophy alone can it be said that it is in the special and autonomatic sense practical, dealing as it does with human conduct with reference to virtue and vice, beatitude and misery. All other sciences are called speculative: they are not concerned with the deeds of the present or future life affecting man's salvation or damnation. All procedures of art and of nature are directed to these moral actions, and exist on account of them. They are of no account except in that they help forward right action. Thus practical and operative sciences, as experimental alchemy and the rest, are regarded as speculative in reference to the operations with which moral or political science is concerned. This science is the mistress of every department of philosophy. It employs and controls them for the advantage of states and kingdoms. It directs the choice of men who are to study in sciences and arts for the common good. It orders all members of the state or kingdom so that none shall remain without his proper work.

“[B]ecause that which is finite is always bounded with reference to something… it is necessary that there should be no end… [N]umber also appears to be infinite, and mathematical magnitudes, and that which is beyond the heavens. And since that which is beyond is infinite, body also appears to be infinite, and it would seem that there are infinite worlds; for why is there rather void here than there? …If also there is a vacuum, and an infinite place, it is necessary that there should be an infinite body: for in things which have a perpetual subsistence, capacity differs nothing from being. The speculation of the infinite is, however, attended with doubt: for many impossibilities happen both to those who do not admit that it has a subsistence, and to those who do. …It is …especially the province of a natural philosopher to consider if there be a sensible infinite magnitude.”

The German Ideology (1845/46)
Context: Where speculation ends — in real life — there real, positive science begins: the representation of the practical activity, of the practical process of development of men. Empty talk about consciousness ceases, and real knowledge has to take place. When reality is depicted, philosophy as an independent branch of activity loses its medium of existence. At the best its place can only be taken by a summing-up of the most general results, abstractions which arise from the observation of the historical development of men. Viewed apart from real history, these abstractions have in themselves no value whatsoever. They can only serve to facilitate the arrangement of historical material, to indicate the sequence of its separate strata. But they by no means afford a recipe or schema, as does philosophy, for neatly trimming the epochs of history. On the contrary, our difficulties begin only when we set about the observation and the arrangement — the real depiction — of our historical material, whether of a past epoch or of the present.

1910s, The World Movement (1910)
Context: Hitherto every civilization that has arisen has been able to develop only a comparatively few activities; that is, its field of endeavor has been limited in kind as well as in locality. There have, of course, been great movements, but they were of practically only one form of activity; and, although usually this set in motion other kinds of activities, such was not always the case. The great religious movements have been the pre-eminent examples of this type. But they are not the only ones. Such peoples as the Mongols and the Phoenicians, at almost opposite poles of cultivation, have represented movements in which one element, military or commercial, so overshadowed all other elements that the movement died out chiefly because it was one-sided. The extraordinary outburst of activity among the Mongols of the thirteenth century was almost purely a military movement, without even any great administrative side; and it was therefore well-nigh purely a movement of destruction. The individual prowess and hardihood of the Mongols, and the perfection of their military organization rendered their armies incomparably superior to those of any European, or any other Asiatic, power of that day. They conquered from the Yellow Sea to the Persian Gulf and the Adriatic; they seized the imperial throne of China; they slew the Caliph in Bagdad; they founded dynasties in India. The fanaticism of Christianity and the fanaticism of Mohammedanism were alike powerless against them. The valor of the bravest fighting men in Europe was impotent to check them. They trampled Russia into bloody mire beneath the hoofs of their horses; they drew red furrows of destruction across Poland and Hungary; they overthrew with ease any force from western Europe that dared encounter them. Yet they had no root of permanence; their work was mere evil while it lasted, and it did not last long; and when they vanished they left hardly a trace behind them. So the extraordinary Phoenician civilization was almost purely a mercantile, a business civilization, and though it left an impress on the life that came after, this impress was faint indeed compared to that left, for instance, by the Greeks with their many-sided development. Yet the Greek civilization itself fell because this many-sided development became too exclusively one of intellect, at the expense of character, at the expense of the fundamental qualities which fit men to govern both themselves and others. When the Greek lost the sterner virtues, when his soldiers lost the fighting edge, and his statesmen grew corrupt, while the people became a faction-torn and pleasure-loving rabble, then the doom of Greece was at hand, and not all their cultivation, their intellectual brilliancy, their artistic development, their adroitness in speculative science, could save the Hellenic peoples as they bowed before the sword of the iron Roman.

“When families have less to spend, that means businesses have fewer customers, and households rack up greater mortgage and credit card debt; meanwhile, concentrated wealth at the top is less likely to result in the kind of broadly based consumer spending that drives our economy, and together with lax regulation, may contribute to risky speculative bubbles.”

Context: So let me repeat: The combined trends of increased inequality and decreasing mobility pose a fundamental threat to the American Dream, our way of life, and what we stand for around the globe. And it is not simply a moral claim that I’m making here. There are practical consequences to rising inequality and reduced mobility. For one thing, these trends are bad for our economy. One study finds that growth is more fragile and recessions are more frequent in countries with greater inequality. And that makes sense. When families have less to spend, that means businesses have fewer customers, and households rack up greater mortgage and credit card debt; meanwhile, concentrated wealth at the top is less likely to result in the kind of broadly based consumer spending that drives our economy, and together with lax regulation, may contribute to risky speculative bubbles.

“When someone goes to the doctor and says, "I hear a voice in my head," he or she will most likely be sent to a psychiatrist. The fact is that, in a very similar way, virtually everyone hears a voice, or several voices, in their head all the time: the involuntary thought processes that you don't realize you have the power to stop. Continuous monologues or dialogues. You have probably come across "mad" people in the street incessantly talking or muttering to themselves. Well, that's not much different from what you and all other "normal" people do, except that you don't do it out loud. The voice comments, speculates, judges, compares, complains, likes, dislikes, and so on. The voice isn't necessarily relevant to the situation you find yourself in at the time; it may be reviving the recent or distant past or rehearsing or imagining possible future situations. Here it often imagines things going wrong and negative outcomes; this is called worry.”

“Where speculation ends — in real life — there real, positive science begins: the representation of the practical activity, of the practical process of development of men. Empty talk about consciousness ceases, and real knowledge has to take place. When reality is depicted, philosophy as an independent branch of activity loses its medium of existence. At the best its place can only be taken by a summing-up of the most general results, abstractions which arise from the observation of the historical development of men. Viewed apart from real history, these abstractions have in themselves no value whatsoever. They can only serve to facilitate the arrangement of historical material, to indicate the sequence of its separate strata. But they by no means afford a recipe or schema, as does philosophy, for neatly trimming the epochs of history. On the contrary, our difficulties begin only when we set about the observation and the arrangement — the real depiction — of our historical material, whether of a past epoch or of the present.”

“The fact is, therefore, that definite individuals who are productively active in a definite way enter into these definite social and political relations. Empirical observation must in each separate instance bring out empirically, and without any mystification and speculation, the connection of the social and political structure with production. The social structure and the state are continually evolving out of the life-process of definite individuals, but of individuals, not as they appear in their own or other people's imagination, but as they really are; i.e. as they are effective, produce materially, and are active under definite material limits, presuppositions and conditions independent of their will.
The production of ideas, of conceptions, of consciousness, is at first directly interwoven with the material activity and the material intercourse of men, the language of real life. Conceiving, thinking, the mental intercourse of men, appear at this stage as the direct efflux of their material behaviour. The same applies to mental production as expressed in the language of the politics, laws, morality, religion, metaphysics of a people. Men are the producers of their conception, ideas, etc.”

Karl Marx book The German Ideology

real, active men, as they are conditioned by a definite development of their productive forces and of the intercourse corresponding to these, up to its furthest forms. Consciousness can never be anything else than conscious existence, and the existence of men is their actual life-process. If in all ideology men and their circumstances appear upside down as in a camera obscura, this phenomenon arises just as much from their historical life-process as the inversion of objects on the retina does from their physical life-process.

Letter 56 (60), to Hugo Boxel (1674) http://oll.libertyfund.org/?option=com_staticxt&staticfile=show.php%3Ftitle=1711&chapter=144218&layout=html&Itemid=27 Source: The Letters Context: When you say that if I deny, that the operations of seeing, hearing, attending, wishing, &c., can be ascribed to God, or that they exist in him in any eminent fashion, you do not know what sort of God mine is; I suspect that you believe there is no greater perfection than such as can be explained by the aforesaid attributes. I am not astonished; for I believe that, if a triangle could speak, it would say, in like manner, that God is eminently triangular, while a circle would say that the divine nature is eminently circular. Thus each would ascribe to God its own attributes, would assume itself to be like God, and look on everything else as ill-shaped. The briefness of a letter and want of time do not allow me to enter into my opinion on the divine nature, or the questions you have propounded. Besides, suggesting difficulties is not the same as producing reasons. That we do many things in the world from conjecture is true, but that our redactions are based on conjecture is false. In practical life we are compelled to follow what is most probable; in speculative thought we are compelled to follow truth. A man would perish of hunger and thirst, if he refused to eat or drink, till he had obtained positive proof that food and drink would be good for him. But in philosophic reflection this is not so. On the contrary, we must take care not to admit as true anything, which is only probable. For when one falsity has been let in, infinite others follow. Again, we cannot infer that because sciences of things divine and human are full of controversies and quarrels, therefore their whole subject-matter is uncertain; for there have been many persons so enamoured of contradiction, as to turn into ridicule geometrical axioms.

“Society is indeed a contract. Subordinate contracts for objects of mere occasional interest may be dissolved at pleasure — but the state ought not to be considered as nothing better than a partnership agreement in a trade of pepper and coffee, calico or tobacco, or some other such low concern, to be taken up for a little temporary interest, and to be dissolved by the fancy of the parties. It is to be looked on with other reverence; because it is not a partnership in things subservient only to the gross animal existence of a temporary and perishable nature. It is a partnership in all science; a partnership in all art; a partnership in every virtue, and in all perfection. As the ends of such a partnership cannot be obtained in many generations, it becomes a partnership not only between those who are living, but between those who are to be born. Each contract of each particular state is but a clause in the great primaeval contract of eternal society, linking the lower with the higher natures, connecting the visible and the invisible world, according to a fixed compact sanctioned by the inviolable oath which holds all physical and all moral natures, each in their appointed place. This law is not subject to the will of those, who by an obligation above them, and infinitely superior, are bound to submit their will to that law. The municipal corporations of that universal kingdom are not morally at liberty at their pleasure, and on their speculations of a contingent improvement, wholly to separate and tear asunder the bands of their subordinate community, and to dissolve it into an unsocial, uncivil, unconnected chaos of elementary principles. It is the first and supreme necessity only, a necessity that is not chosen, but chooses, a necessity paramount to deliberation, that admits no discussion, and demands no evidence, which alone can justify a resort to anarchy. This necessity is no exception to the rule; because this necessity itself is a part too of that moral and physical disposition of things, to which man must be obedient by consent or force: but if that which is only submission to necessity should be made the object of choice, the law is broken, nature is disobeyed, and the rebellious are outlawed, cast forth, and exiled, from this world of reason, and order, and peace, and virtue, and fruitful penitence, into the antagonist world of madness, discord, vice, confusion, and unavailing sorrow.”

“Normally, anyone disreputable enough to flatly affirm such positive proclamations without adequate support would lose the respect of his peers and be accused of outright fraud; anyone but a religious advocate that is. When allegedly holy men do the exact same thing, then its not called fraud anymore. Its called “revealed truth” instead. That’s quite a double-standard, innit? Like when some minister gets on stage at one of those stadium-sized churches -to state as fact who God is and what God is, and what he wants, hates, needs, won’t tolerate, or will do -for whom, how, and under what conditions; they don’t have any data to show they’re correct about any of it, yet they speak so matter-of-factly. Even when they contradict each other they’re all still completely confident in their own empty assertions! So why do none of these tens of thousands of head-bobbing, mouth-breathing, glassy-eyed wanna-believers have the presence of mind to ask, “how do you know that?” Well, for all those who never asked the question, here’s the answer; they don’t know that! There’s no way anyone could know these things. They’re making it up as they go along. These sermons are the best possible example of blind speculation; asserted as though it were truth and sold for tithe. If anyone or everyone else would be called liars for claiming such things without any evidentiary basis then why make exceptions for evangelists? For these charlatans are obviously liars too!
