Philosophers From England

"Secondary Qualities are not 'extended' but 'intensive'; their effects are not augmented by addition of parts, but by increased operation of the medium. Hence they are not measured directly, but by 'scales'; not by 'units', but by 'degrees'."

"Coexistent polarities are fundamentally identical."

"The Science of Hydrostatics depends upon the Fundamental Principle that 'fluids press equally in all directions'. This Principle necessarily results from the conception of a Fluid, as a body of which the parts are perfectly moveable in all directions. For since the Fluid is a body, it can transmit pressure; and the transmitted pressure is equal to the original pressure, in virtue of the Axiom that Reaction is equal to Action. That the Fundamental Principle is not derived from experience, is plain both from its evidence and from its history."

"The Idea of Cause is expressed for purposes of science by these three Axioms:—'Every Event must have a Cause':—'Causes are measured by their Effects':—'Reaction is equal and opposite to Action'."

"Mechanical Science depends on the Conception of Force; and is divided into 'Statics', the doctrine of Force preventing motion, and 'Dynamics', the doctrine of Force producing motion."

"Among the foundations of the Higher Mathematics is also the 'Idea of a Limit'. The Idea of a Limit cannot be superseded by any other definitions or Hypotheses."

"Attractions take place between bodies, affinities between the particles of a body. The former may be compared to the alliances of states, the latter to the ties of family."

"Mechanical, chemical, and vital Forces form an ascending progression, each including the preceding. Chemical Affinity includes in its nature Mechanical Force, and may often be practically resolved into Mechanical Force. (Thus the ingredients of gunpowder, liberated from their chemical union, exert great mechanical Force : a galvanic battery acting by chemical process does the like.) Vital Forces include in their nature both chemical Affinities and mechanical Forces: for Vital Powers produce both chemical changes, (digestion,) and motions which imply considerable mechanical force, (as the motion of the sap and of the blood.)"

"'When two equal weights are supported on the middle point between them, the pressure on the fulcrum is equal to the sum of the weights.'"

"It is better to form new words as technical terms, than to employ old ones in which the last three Aphorisms cannot be complied with."

"Truths obtained by Induction are made compact and permanent by being expressed in 'Technical Terms'."

"In Deductive Reasoning, we cannot have any truth in the conclusion which is not virtually contained in the premises."

"Truths once obtained by legitimate Induction are Facts: these Facts may be again connected, so as to produce higher truths: and thus we advance to 'Successive Generalizations'."

"The antithesis of 'Sense' & 'Ideas' is the foundation of the Philosophy of Science. No knowledge can exist without the union, no philosophy without the separation, of these two elements."

"The Sensations are the 'Objective', the Ideas the 'Subjective' part of every act of perception or knowledge."

"In order to acquire any exact and solid knowledge, the student must possess with perfect precision the ideas appropriate to that part of knowledge: and this precision is tested by the student's 'perceiving' the axiomatic evidence of the 'axioms' belonging to each 'Fundamental Idea'."

"Man, servant and interpreter of Nature, does and understands only as much as he has observed of the order of Nature, either in reality or in mind; he neither knows nor can do more."

"A scientific writer of modern times appears to wonder that men did not at once divine the weight of the air from which the phenomena formerly ascribed to the 'fuga vacui' really result. “Loaded, compressed by the atmosphere,” he says, “they did not recognize its action. In vain all Nature testified that air was elastic and heavy; they shut their eyes to her testimony. The water rose in pumps and flowed in siphons at that time as it does at this day. They could not separate the boards of a pair of bellows of which the holes were stopped; and they could not bring together the same boards without difficulty if they were at first separated. Infants sucked the milk of their mothers; air entered rapidly into the lungs of animals at every inspiration; cupping-glasses 'produced tumours on the skin; and in spite of all these striking proofs of the weight and elasticity of the air, the ancient philosophers maintained resolutely that air was light, and explained all these phenomena by the horror which they said Nature had for a vacuum.” It is curious that it should not have occurred to the author while writing this, that if these facts, so numerous and various, can all be accounted for by one principle, there is a strong presumption that the principle is not altogether baseless. And in reality is it not true that Nature does abhor a vacuum, and do all she can to avoid it? No doubt this power is not unlimited; and we can trace it to a mechanical cause, the pressure of the circumambient air. But the tendency, arising from this pressure, which the bodies surrounding a space void of air have to rush into it, may be expressed, in no extravagant or unintelligible manner, by saying that Nature has a repugnance to a vacuum."

"Our assent to the hypothesis implies that it is held to be true of all particular instances. That these cases belong to past or to future times, that they have or have not already occurred, makes no difference in the applicability of the rule to them. Because the rule prevails, it includes all cases."

"By speaking of space as an Idea, I intend to imply the apprehension of objects as existing in space, and of the relations of position prevailing among them, is not a consequence of experience but a result of a peculiar constitution and activity of the mind which is independent of all experience in its origin, though constantly combined with experience in its exercise."

"'Form' or 'figure' is space limited by boundaries. Space has necessarily 'three' dimensions, length, breadth, depth; and no ethers which cannot be resolved into these."

"According to the technical language of old writers, a thing and its qualities are described as subject and attributes; and thus a man’s faculties and acts are attributes of which he is the subject. The mind is the subject in which ideas inhere. Moreover, the man’s faculties and acts are employed upon external objects; and from objects all his sensations arise. Hence the part of a man’s knowledge which belongs to his own mind, is subjective: that which flows in upon him from the world external to him, is objective."

"We unfold out of the Idea of Space the propositions of geometry, which are plainly truths of the most rigorous necessity and universality. But if the idea of space were merely collected from observation of the external world, it could never enable or entitle us to assert such propositions: it could never authorize us to say that not merely some lines, but all lines, not only have, but must have, those properties which geometry teaches. Geometry in every proposition speaks a language which experience never dares to utter; and indeed of which she but half comprehends the meaning."

"The system becomes more coherent as it is further extended. The elements which we require for explaining a new class of facts are already contained in our system. Different members of the theory run together, and we have thus a constant convergence to unity. In false theories, the contrary is the case."

"And so no force however great can stretch a cord however fine into an horizontal line which is accurately straight."

"We cannot observe external things without some degree of Thought; nor can we reflect upon our Thoughts, without being influenced in the course of our reflection by the Things which we have observed."

"Every failure is a step to success. Every detection of what is false directs us towards what is true: every trial exhausts some tempting form of error. Not only so; but scarcely any attempt is entirely a failure; scarcely any theory, the result of steady thought, is altogether false; no tempting form of Error is without some latent charm derived from Truth."

"The Perception of Time involves a constant and latent kind of memory, which may be termed a 'Sense of Succession'. The Perception of Number also involves this Sense of Succession, although in small numbers we appear to apprehend the units simultaneously and not successively."

"Terms must be constructed and appropriated so as to be fitted to enunciate simply and clearly true general propositions."

"'Intuitive' is opposed to 'discursive' reason. In intuition, we obtain our conclusions by dwelling upon 'one' aspect of the fundamental Idea; in discursive reasoning, we combine several aspects of the Idea"

"New terms and changes of terms, which are not needed in order to express truth, are to be avoided."

"[P]hilological analogies are to be preserved if possible, but modified according to scientific convenience."

"When alterations in technical terms become necessary, it is desirable that the new term should contain in its form some memorial of the old one."

"Many glaring errors of the Greeks will have to be noticed ... few of them can be referred to the cause assigned by Dr. Whewell."

"Terms which imply theoretical views are admissible, as far as the theory is proved."

"If terms are systematically good, they are not to be rejected because they are etymologically inaccurate."

"The fundamental terms of a system of Nomenclature may "be conveniently borrowed from casual or arbitrary circumstances."

"In forming a Terminology, words may be invented when necessary, but they cannot be conveniently borrowed from casual or arbitrary circumstances."

"With the signing of the Treaties of Utrecht, Bolingbroke's one great achievement in the world of action was accomplished. The rest of his political career, after a Niagara leap into rebellion, was to be lost in shallows and in miseries. But he stands in history as the man who, by courses however devious and questionable, negotiated a Peace which proved in the working more satisfactory than any other that has ended a general European conflict in modern times."

"[T]he accomplishments of his mind, which was adorned with the choicest gifts that God has yet thought fit to bestow upon the children of men; a strong memory, a clear judgment, a vast range of wit and fancy, a thorough comprehension, an invincible eloquence, with a most agreeable elocution."

"Awake, my St. John, leave all meaner things To low ambition, and the pride of kings. Laugh when we must, be candid when you can, And vindicate the ways of God to man."

"I think Mr. secretary St. John the greatest young man I ever knew: wit, capacity, beauty, quickness of apprehension, good learning, and an excellent taste; the best orator in the house of commons, admirable conversation, good nature, and good manners; generous, and a despiser of money. His only fault is, talking to his friends in way of complaint of too great load of business, which looks a little like affectation; and he endeavours too much to mix the fine gentleman, and the man of pleasure, with the man of business. What truth and sincerity he may have, I know not."

"He was called indeed a tory; but his writings prove him a stronger advocate for liberty than any of his countrymen, the whigs of the present day. Irritated by his exile, he committed one act unworthy of him, in connecting himself momentarily with a prince rejected by his country. But he redeemed that single act by his establishment of the principles which proved it to be wrong... Lord Bolingbroke's...is a style of the highest order. The lofty, rhythmical, full-flowing eloquence of Cicero. Periods of just measure, their members proportioned, their close full and round. His conceptions, too, are bold and strong, his diction copious, polished and commanding as his subject. His writings are certainly the finest samples in the English language, of the eloquence proper for the Senate. His political tracts are safe reading for the most timid religionist, his philosophical, for those who are not afraid to trust their reason with discussions of right and wrong."

"He engaged young, and distinguished himself in business; and his penetration was almost intuition. I am old enough to have heard him speak in parliament. And I remember that, though prejudiced against him by party, I felt all the force and charms of his eloquence. Like Belial in Milton, “he made the worse appear the better cause.” All the internal and external advantages and talents of an orator are undoubtedly his. Figure, voice, elocution, knowledge, and, above all, the purest and most florid diction, with the justest metaphors and happiest images, had raised him to the post of Secretary at War, at four-and-twenty years old, an age at which others are hardly thought fit for the smallest employments."

"Lord Bolingbroke, one of the ablest men who ever lived, was a firm and uncompromising Tory, and he advocated triennial Parliaments. He said that without this there was no security for the people, no integrity for the constitution."

"Who now reads Bolingbroke? Who ever read him through? ... I do not often quote Bolingbroke, nor have his works in general, left any permanent impression on my mind. He is a presumptuousness and a superficial writer. But he has one observation, which in my opinion, is not without depth and solidity. He says, that he prefers a monarchy to other governments; because you can better ingraft any description of republic on a monarchy than any thing of monarchy upon the republican forms. I think him perfectly in the right."

"In his place, concord will appear, brooding peace and prosperity on the happy land; joy fitting in every face, content in every heart; a people unoppressed, undisturbed, unalarmed; busy to improve their private property and the public stock; fleets covering the ocean; bringing home wealth by the returns of industry; carrying assistance or terror abroad by the direction of wisdom; and asserting triumphantly the right and the honour of Great Britain, as far as waters roll and as winds can waft them. Those who live to see such happy days, and to act in so glorious a scene, will perhaps call to mind with some tenderness of sentiment, when he is no more, a man, who contributed his mite to carry on so good a work, and who desired life for nothing so much, as to see a king of Great Britain the most popular man in his country, and a patriot king at the head of an united people."

"Bolingbroke was typical not only in his attempt to define the true interests of the state but also in his use of the analogy between the political society and the family to assert that not unity but discord was the natural relationship between states. The personal needs of men were met by the development of society out of the family. Self-love, which originally assisted this development and produced separate societies, then ensured that the development would spread no further. "The great commonwealth of mankind cannot be brought under one government, nor subsist without any." As Bolingbroke used these views to make himself an early advocate of a maritime, insular, colonial Great Britain, intervening in European affairs only when her interest in the balance of power required it, so the continental writers of his time completely abandoned the traditional belief in Christendom or Europe as a structure above or at least additional to its component states."

"The French may improve their natural wealth and power by the improvement of trade and commerce. We can have no wealth, nor power by consequence, as Europe is now constituted, without the improvement of them, nor in any degree but proportionably to this improvement."

"The result of what has been said is, in general, that the wealth and power of all nations depending so much on their trade and commerce, and every nation being...in such different circumstances of advantage or disadvantage in the pursuit of this common interest; a good government, and therefore the government of a patriot king, will be directed constantly to make the most of every advantage that nature has given, or art can procure towards the improvement of trade and commerce. And this is one of the principal criterions, by which we are to judge whether governors are in the true interest of the people, or not. It results, in particular, that Great Britain might improve her wealth and power in a proportion superior to that of any nation who can be deemed her rival, if the advantages she has were as wisely cultivated, as they will be in the reign of a patriot king."
