"For instance, if you have by a lie hindered a man who is even now planning a murder, you are legally responsible for all the consequences. But if you have strictly adhered to the truth, public justice can find no fault with you, be the unforeseen consequence what it may. It is possible that whilst you have honestly answered Yes to the murderer’s question, whether his intended victim is in the house, the latter may have gone out unobserved, and so not have come in the way of the murderer, and the deed therefore have not been done; whereas, if you lied and said he was not in the house, and he had really gone out (though unknown to you) so that the murderer met him as he went, and executed his purpose on him, then you might with justice be accused as the cause of his death. For, if you had spoken the truth as well as you knew it, perhaps the murderer while seeking for his enemy in the house might have been caught by neighbours coming up and the deed been prevented."
"The Palestinians living among us have, for the most part, earned a not unfounded reputation for being cheaters, because of their spirit of usury since their exile. Certainly, it seems strange to conceive of a nation of cheaters; but it is just as odd to think of a nation of merchants, the great majority of whom, bound by an ancient superstition that is recognized by the State they live in, seek no civil dignity and try to make up for this loss by the advantage of duping the people among whom they find refuge, and even one another. The situation could not be otherwise, given a whole nation of merchants, as non-productive members of society (for example, the Jews in Poland)."
"What vexations there are in the external customs which are thought to belong to religion, but which in reality are related to ecclesiastical form! The merits of piety have been set up in such away that the ritual is of no use at all except for the simple submission of the believers to ceremonies and observances, expiations and mortifications (the more the better). But such compulsory services, which are mechanically easy (because no vicious inclination is thus sacrificed), must be found morally very difficult and burdensome to the rational man. When, therefore, the great moral teacher said, 'My commandments are not difficult,' he did not mean that they require only limited exercise of strength in order to be fulfilled. As a matter of fact, as commandments which require pure dispositions of the heart, they are the hardest that can be given. Yet, for a rational man, they are nevertheless infinitely easier to keep than the commandments involving activity which accomplishes nothing... [since] the mechanically easy feels like lifting hundredweights to the rational man when he sees that all the energy spent is wasted."
"Habit... makes the endurance of evil easy (which, under the name of patience, is falsely honored as a virtue), because sensations of the same type, when continued without alteration for a long time, draw our attention away from the senses so that we are scarcely conscious of them at all. On the other hand, habit also makes the consciousness and the remembrance of good that has been received more difficult, which then gradually leads to ingratitude (a real vice). [...] Acquired habit deprives good actions of their moral value because it undermines mental freedom and, moreover, it leads to thoughtless repetitions of the same acts (monotony), and thus becomes ridiculous."
"Collectively, the more civilized men are, the more they are actors. They assume the appearance of attachment, of esteem for others, of modesty, and of disinterestedness, without ever deceiving anyone, because everyone understands that nothing sincere is meant. Persons are familiar with this, and it is even a good thing that this is so in this world, for when men play these roles, virtues are gradually established, whose appearance had up until now only been affected. These virtues ultimately will become part of the actor's disposition. To deceive the deceiver in ourselves, or the tendency to deceive, is a fresh return to obedience[.]"
"Young man! Deny yourself satisfaction (of amusement, of debauchery, of love, etc.), not with the Stoical intention of complete abstinence, but with the refined Epicurean intention of having in view an ever-growing pleasure. This stinginess with the cash of your vital urge makes you definitely richer through the postponement of pleasure, even if you should, for the most part, renounce the indulgence of it until the end of your life. The awareness of having pleasure under your control is, like everything idealistic, more fruitful and more abundant than everything that satisfies the sense through indulgence because it is thereby simultaneously consumed and consequently lost from the aggregate of totality."
"[T]o require that a so-called layman should not use his own reason in religious matters, particularly since religion is to be appreciated as moral, but instead follow the appointed clergyman and thus someone else's reason, is an unjust demand because as to morals every man must account for all his doings. The clergyman will not and even cannot assume such a responsibility."
"The guidelines for achieving wisdom consist of three leading maxims: 1) Think for yourself; 2) (in communication with other people) Put yourself in the place of the other person; 3) Always think by remaining faithful to your own self."
"A mind of slow apprehension is therefore not necessarily a weak mind. The one who is alert with abstractions is not always profound, he is more often very superficial."
"Through failures one becomes intelligent; but the one who has trained himself in this subject so that he can make others wise through their own failures, has used his intelligence. Ignorance is not stupidity."
"The deceiver is really the fool."
"[W]hat alone has value is the use to which life is put and the end to which it is directed. The value of life has to be created by man, it cannot be obtained through luck but only through wisdom. He who is anxiously concerned over losing his life will never enjoy life."
"Money is the password, and all doors, which are closed to the man of lesser means, fly open to those whom Plutus favors. The invention of money, which has no other usefulness (or at least it should not have any) except for the commercial exchange of the products of man's industry, now serves all that is physically good among men. Especially after money was represented by metal, it has produced avarice which, finally, without indulgence, but by its mere possession, and even with the resolution (of the stingy) not to spend it, still contains a power which people believe can sufficiently compensate for the lack of any other power."
"[T]his species works intentionally on its own destruction (by war). This, however, does not keep the rational creatures of such a constantly advancing culture, even in the midst of war, from promising to mankind in coming centuries an unequivocal prospect of bliss which will never end."
"The man of principles has character. Of him we know definitely what to expect. He does not act on the basis of his instinct, but on the basis of his will. Therefore, without being redundant one can classify characteristics according to a person's faculty of desire (what is practical), as a) his nature, or natural talent, b) his temperament, or disposition, and c) his general character, or mode of thinking."
"All... good and useful properties of character have a price in exchange for others which have just as much use. Talent has a market price, since the sovereign or estate-owner can use a talented person in all sorts of ways. Temperament has a fancy price,22 since one can converse well with such a person; he is a pleasant companion. But, character has an inner value[,] and it is above all price."
"Nature made women mature early and had them demand gentle and polite treatment from men, so that they would find themselves imperceptibly fettered by a child due to their own magnanimity; and they would find themselves brought, if not quite to morality itself, then at least to that which cloaks it, moral behavior, which is the preparation and introduction to morality."
"The woman wants to dominate, the man wants to be dominated[.]"
"England and France, the two most civilized nations on earth, who are in contrast to each other because of their different characters, are, perhaps chiefly for that reason, in constant feud with one another. Also, England and France, because of their inborn characters, of which the acquired and artificial character is only the result, are probably the only nations who can be assumed to have a particular and, as long as both national characters are not blended by the force of war, unalterable characteristics. That French has become the universal language of conversation, especially in the feminine world, and that English is the most widely used language of commerce among tradesmen, probably reflects the difference in their continental and insular geographic situation."
"[T]he first characteristic of the human species is man's ability, as a rational being, to establish character for himself, as well as for the society into which nature has placed him. This ability, however, presupposes an already favorable natural predisposition and an inclination to the good in man, because the evil is really without character (since it is at odds with itself, and since it does not tolerate any lasting principle within itself)"
"If you punish a child for being naughty, and reward him for being good, he will do right merely for the sake of the reward; and when he goes out into the world and finds that goodness is not always rewarded, nor wickedness always punished, he will grow into a man who only thinks about how he may get on in the world, and does right or wrong according as he finds either of advantage to himself."
"The child must be brought up free (that he allow others to be free). He must learn to endure the restraint to which freedom subjects itself for its own preservation (experience no subordination to his command). Thus he must be disciplined. This precedes instruction. Training must continue without interruption. He must learn to do without things and to be cheerful about it. He must not be obliged to dissimulate, he must acquire immediate horror of lies, must learn so to respect the rights of men that they become an insurmountable wall for him. His instruction must be more negative. He must not learn religion before he knows morality. He must be refined, but not spoiled (pampered). He must learn to speak frankly, and must assume no false shame. Before adolescence he must not learn fine manners ; thoroughness is the chief thing. Thus he is crude longer, but earlier useful and capable."
"Good and strong will. Mechanism must precede science (learning). Also in morals and religion? Too much discipline makes one narrow and kills proficiency. Politeness belongs, not to discipline, but to polish, and thus comes last."
"There must be a seed of every good thing in the character of men, otherwise no one can bring it out. Lacking that, analogous motives, honor, etc., are substituted. Parents are in the habit of looking out for the inclinations, for the talents and dexterity, perhaps for the disposition of their children, and not at all for their heart or character."
"Character means that the person derives his rules of conduct from himself and from the dignity of humanity. Character is the common ruling principle in man in the use of his talents and attributes. Thus it is the nature of his will, and is good or bad. A man who acts without settled principles, with no uniformity, has no character. A man may have a good heart and yet no character, because he is dependent upon impulses and does not act according to maxims. Firmness and unity of principle are essential to character."
"The more one presupposes that his own power will suffice him to realize what he desires the more practical is that desire. When I treat a man contemptuously, I can inspire him with no practical desire to appreciate my grounds of truth. When I treat any one as worthless, I can inspire him with no desire to do right."
"The evil effect of science upon men is principally this, that by far the greatest number of those who wish to display a knowledge of it accomplish no improvement at all of the understanding, but only a perversity of it, not to mention that it serves most of them as a tool of vanity."
"Man's greatest concern is to know how he shall properly fill his place in the universe and correctly understand what he must be in order to be a man."
"I am an investigator by inclination. I feel a great thirst for knowledge and an impatient eagerness to advance, also satisfaction at each progressive step. There was a time when I thought that all this could constitute the honor of humanity, and I despised the mob, which knows nothing about it. Rousseau set me straight. This dazzling excellence vanishes; I learn to honor men, and would consider myself much less useful than common laborers if I did not believe that this consideration could give all the others a value, to establish the rights of humanity."
"In the metaphysical elements of aesthetics the various nonmoral feelings are to be made use of; in the elements of moral metaphysics the various moral feelings of men, according to the differences in sex, age, education, and government, of races and climates, are to be employed."
"In the natural state no concept of God can arise, and the false one which one makes for himself is harmful. Hence the theory of natural religion can be true only where there is no science; therefore it cannot bind all men together."
"Man has his own inclinations and a natural will which, in his actions, by means of his free choice, he follows and directs. There can be nothing more dreadful than that the actions of one man should be subject to the will of another; hence no abhorrence can be more natural than that which a man has for slavery. And it is for this reason that a child cries and becomes embittered when he must do what others wish, when no one has taken the trouble to make it agreeable to him. He wants to be a man soon, so that he can do as he himself likes."
"Suicide evokes revulsion with horror, because everything in nature seeks to preserve itself: a damaged tree, a living body, an animal; and in man, then, is freedom, which is the highest degree of life, and constitutes the worth of it, to become now a principium for self-destruction? This is the most horrifying thing imaginable. For anyone who has already got so far as to be master, at any time, over his own life, is also master over the life of anyone else; for him, the door stands open to every crime, and before he can be seized he is ready to spirit himself away out of the world. So suicide evokes horror, in that a man thereby puts himself below the beasts. We regard a suicide as a carcase, whereas we feel pity for one who meets his end through fate."
"A person who already displays … cruelty to animals is also no less hardened towards men. We can already know the human heart, even in regard to animals."
"The more we devote ourselves to observing animals and their behaviour, the more we love them, on seeing how gready they care for their young; in such a context, we cannot even contemplate cruelty to a wolf. Leibnitz put the grub he had been observing back on the tree with its leaf, lest he should be guilty of doing any harm to it. It upsets a man to destroy such a creature for no reason, and this tenderness is subsequently transferred to man."
"Thus our duties to animals are indirectly duties to humanity."
"Experience without theory is blind, but theory without experience is mere intellectual play."
"Do what is right, though the world may perish."
"To be is to do."
"If the truth shall kill them, let them die."
"[Clausewitz] quite understands that you must break the enemy's will, for which he suggests three processes: first to crush his army, and then to take his capital and, if that is not enough, to occupy his territory."
"We must renounce attempts at building an absolute revolutionary strategy out of the elements of our limited experience of the three years of civil war, during which units of a particular quality fought under particular conditions. Clausewitz warned very well against this. "What could be more natural," he wrote, "than the fact that war of the French Revolution had its characteristic style, and what theory could have been expected to accommodate it? The danger is that this kind of style, developed out of a single case, can easily outlive the situation that gave rise to it: for conditions change imperceptibly. That danger is the very thing a theory should prevent by lucid, rational criticism. In 1806 the Prussian generals were under the sway of this methodism", and so on. Alas! Prussian generals are not the only ones with an inclination towards methodism, that is, towards stereotypes and conventional patterns."
"[H]e far transcended the two great inspirations of his life: Scharnhorst and Napoleon. Out of Scharnhorst's fragmentary and aphoristic heritage he developed the systematic, closely knit, perfectly balanced theory, in which every factor, every aspect, every argument had its place from which it could not be removed without fatally endangering the delicate balance of the whole. From the deep appreciation of the revolution wrought by Napoleon in the art of war, he reached an infinitely broader conception embracing within its elastic framework and majestic sweep every conceivable form of warfare and strategy... [T]he impression it made when it was published after his death through the devoted efforts of his widow and friends was extraordinary. The circle of those who noticed it was at first not large, and the magnitude of his achievement, even in its fragmentary form, was far too great to be taken in at once. But his perfect mastery of his subject, the intuitive genius with which he had succeeded in expressing what his contemporaries consciously or subconsciously felt, the charm of his style deeply affected all those who read it. By a process of infiltration, the influence of his ideas spread through the higher ranks of the army, influencing the thoughts of men and replacing the far more superficial, if much more easily assimilable, doctrines of his Swiss contemporary and rival Jomini. That process, going on unobtrusively throughout the middle decades of the 19th Century, came to a full and open conclusion after the sudden death of Reyher when the leadership of the General Staff was entrusted to Moltke, who combined in an almost perfect balance the technical mastery of the conduct of operations developed in the General Staff with his profound insight into the deeper issues developed in Clausewitz's great treatise."
"That the General Staff succeeded in preserving the lessons learned at such cost in the struggle against Napoleon, was to a large extent the work of Clausewitz. Among the whole group of the Reformers, Clausewitz had been from the outset the theoretician par excellence. Not in the sense of a one-sided abstract academic pedant, but as a practical soldier, who at the same time happened to be that rare phenomenon, a natural born theorist; combining a keen appreciation of the requirements of a sound theory, with a unique understanding of the practical uses to which it could be put. During the wars against Napoleon a series of mishaps kept Clausewitz in relatively subordinate positions incommensurate with his exceptional abilities. After the peace had been reestablished, he was confined for twelve dreary years, from 1818 to 1830 to a purely administrative post as military director of the War Academy in Berlin. There, out of the intense feeling of frustration that forced him to seek an outlet for his gifts and energies in his private studies arose a long series of military studies, culminating in his famous treatise On War, the most profound, comprehensive, and systematic examination of war that has appeared to the present day."
"His Protestation of 1812 is by far the purest and most powerful expression of the new spirit of militancy that inspired the patriots of 1812–1813. Among other things it contains a virtual catalogue of political virtues and vices, a brief summary of the new militant political ethic, so to speak. Clausewitz solemnly rejected everything that might buffer the iron necessity of a life-and-death struggle, or that might tempt man to evade it—such things as the "frivolous hope" for a favourable chance; languid inaction while blindly waiting what the future might bring; "unworthy servility and flattery" to appease tyrants; "false resignation" and "unreasoning distrust" of one's own capacity; "culpable neglect of duty" toward the general good; and above all cowardly submission and the "shameless surrender of the country's and people's honour, of the personal dignity of man." What he pledged instead was to shed the last drop of blood for life's freedom and dignity; to put king and country above all else; to regard their preservation as a "most sacred duty"; to "meet danger with manly courage, calm and firm resolve, and full awareness"; to be prepared to make the "supreme sacrifice" without fear or false cunning, free of all selfishness, inspired by the "glorious struggle for freedom and the dignity of the fatherland.""
"Clausewitz was anything but a mere expert, a technician of the military craft. As shown by his poetic and expressive language alone, his way was a truly creative mind, richly endowed, open to all the sensations of nature, the full wealth of the human spirit. All in all he represented a most curious and rare combination of philosophical contemplation and impatience for action, of cold, lucid intellect and passionate sensitivity—a reflective spirit who ardently longed for heroic deeds with an ambition that was never to be fulfilled. He was, therefore, virtually predestined to cast the essence of the Prussian military spirit into a literary form none had found before him."
"If one compares Clausewitz and Foch, one will see that Foch before the World War strongly emphasized the demoralization of the enemy as the military objective; whereas Clausewitz, thinking more coolly and more comprehensively, reminded his readers that the capture or killing of the enemy constitutes in the tactical sphere the final destruction of his ability to fight on, whereas his moral overthrow constitutes only a conditioned, or generally only a temporary elimination."
"Clausewitz's position on domestic issues was heavily influenced by his view of foreign affairs as they affected the security of the Prussian state. He was immune to the Byronic idealisation of liberation and freedom, valued stability, and trusted the balance of power to overcome or contain most international crises, as long as the strongest states had the ability and will to resort to war to defend the independence of the international community. That some smaller states might be sacrificed in the process, he accepted as inevitable. But at the same time he believed that Prussia would be stronger politically and militarily if its passive subjects turned into active citizens, serving in an army made up of regulars and a strong Landwehr, an institution that would give the middle class new openings to influence and power. On domestic affairs Clausewitz's views tended toward liberalism, on foreign affairs toward conservatism. In France and Britain before the Reform Act of 1832, these opinions might have placed him among moderates; in Prussia they sufficed to brand him Jacobin."
"[T]he characterisation of Clausewitz as a conservative fails to place him in the Prussian context, and, on the other hand, does not recognise that in the 1820s even a Briton with Clausewitz's views would have been a very odd Tory indeed. Clausewitz welcomed the destruction of corporative society in Prussia, to which he himself had contributed during the reform era; he believed in equality before the law, in a strong militia or Landwehr based on universal military service, in an independent judiciary, ministerial responsibility, a limited franchise, and a parliament with advisory functions. These views had much in common with early German liberalism, which still considered representative institutions less important than a professional and honest administration and a strong executive, able to defend Germany against east and west. Clausewitz's emphasis on a powerful central authority had conservative implications; yet it placed him in opposition to those conservatives who were more concerned with maintaining the traditional order of society than with increasing the power of the state, and neither Prussian conservatives nor the crown had any patience with the idea of a parliament, however limited its functions."
"By considering a few of Clausewitz's statements in isolation and christening him the "Mahdi of Mass," Basil Liddell Hart portrayed him as an intellectual forerunner of the commanders of the First World War, who for three-and-a-half years found no way out of the stalemate of the Western front, with its hundreds and thousands of casualties each week. For having stated that war was merely the continuation of policy by other means, Clausewitz was charged with minimising differences between peace and war, and thus making war more acceptable. But that accusation was based on a misunderstanding of the larger theoretical purpose of this definition: to identify political decisions as the common cause of war, which—if the leadership was rational—should also determine the degree of violence needed to achieve the political purpose. This misinterpretation fed into the view held by John Keegan, among others, that Clausewitz saw nothing morally reprehensible in war, and that his theories contributed to the boundless violence of the world wars and their ancillary conflicts in the twentieth century. To misread Clausewitz, and then ascribe to his ideas a greater influence than the world's actual experience with Napoleonic war, the vast expansion of armed forces throughout the nineteenth century, industrialisation, modern technology, and new ideologies, is, however, to fail to distinguish between historical events and their analyst."
