“No one can deny the suffering, fear, or panic, the terror or fright that can seize certain animals and that we humans can witness. … No doubt either, then, of there being within us the possibility of giving vent to a surge of compassion, even if it is then misunderstood, repressed, or denied, held at bay. … The two centuries I have been referring to somewhat casually in order to situate the present in terms of this tradition have been those of an unequal struggle, a war (whose inequality could one day be reversed) being waged between, on the one hand, those who violate not only animal life but even and also this sentiment of compassion, and, on the other hand, those who appeal for an irrefutable testimony to this pity. War is waged over the matter of pity. This war is probably ageless but, and here is my hypothesis, it is passing through a critical phase. We are passing through that phase, and it passes through us. To think the war we find ourselves waging is not only a duty, a responsibility, an obligation, it is also a necessity, a constraint that, like it or not, directly or indirectly, no one can escape. Henceforth more than ever. And I say “to think” this war, because I believe it concerns what we call “thinking.””

The animal looks at us, and we are naked before it. Thinking perhaps begins there.

“Both the law of inertia and the law of gravitation contain a numerical factor or a constant belonging to matter, which is called mass. We have thus two definitions of mass; one by the law of inertia: mass is the ratio between force and acceleration. We may call the mass thus defined the inertial or passive mass, as it is a measure of the resistance offered by matter to a force acting on it. The second is defined by the law of gravitation, and might be called the gravitational or active mass, being a measure of the force exerted by one material body on another. The fact that these two constants or coefficients are the same is, in Newton's system, to be considered as a most remarkable accidental coincidence and was decidedly felt as such by Newton himself. He made experiments to determine the equality of the two masses by swinging a pendulum, of which the bob was hollow and could be filled up with different materials. The force acting on the pendulum is proportional to its active mass, its inertia is proportional to its passive mass, so that the period will depend on the ratio of the passive and the active mass. Consequently the fact that the period of all these different pendulums was the same, proves that this ratio is a constant, and can be made equal to unity by a suitable choice of units, i. e., the inertial and the gravitational mass are the same. These experiments have been repeated in the nineteenth century by Bessel, and in our own times by Eötvös and Zeeman, and the identity of the inertial and the gravitational mass is one of the best ascertained empirical facts in physics-perhaps the best. It follows that the so-called fictitious forces introduced by a motion of the body of reference, such as a rotation, are indistinguishable from real forces…. In Einstein's general theory of relativity there is also no formal theoretical difference, as there was in Newton's system…. the equality of inertial and gravitational mass is no longer an accidental coincidence, but a necessity.”

“If justice be not a natural principle, it is no principle at all. If it be not a natural principle, there is no such thing as justice. If it be not a natural principle, all that men have ever said or written about it, from time immemorial, has been said and written about that which had no existence. If it be not a natural principle, all the appeals for justice that have ever been heard, and all the struggles for justice that have ever been witnessed, have been appeals and struggles for a mere fantasy, a vagary of the imagination, and not for a reality.

If justice be not a natural principle, then there is no such thing as injustice; and all the crimes of which the world has been the scene, have been no crimes at all; but only simple events, like the falling of the rain, or the setting of the sun; events of which the victims had no more reason to complain than they had to complain of the running of the streams, or the growth of vegetation.

If justice be not a natural principle, governments (so-called) have no more right or reason to take cognizance of it, or to pretend or profess to take cognizance of it, than they have to take cognizance, or to pretend or profess to take cognizance, of any other nonentity; and all their professions of establishing justice, or of maintaining justice, or of rewarding justice, are simply the mere gibberish of fools, or the frauds of imposters.

But if justice be a natural principle, then it is necessarily an immutable one; and can no more be changed—by any power inferior to that which established it—than can the law of gravitation, the laws of light, the principles of mathematics, or any other natural law or principle whatever; and all attempts or assumptions, on the part of any man or body of men—whether calling themselves governments, or by any other name—to set up their own commands, wills, pleasure, or discretion, in the place of justice, as a rule of conduct for any human being, are as much an absurdity, an usurpation, and a tyranny, as would be their attempts to set up their own commands, wills, pleasure, or discretion in the place of any and all the physical, mental, and moral laws of the universe.

If there be any such principle as justice, it is, of necessity, a natural principle; and, as such, it is a matter of science, to be learned and applied like any other science. And to talk of either adding to, or taking from, it, by legislation, is just as false, absurd, and ridiculous as it would be to talk of adding to, or taking from, mathematics, chemistry, or any other science, by legislation.”

“The rule is derived inductively from experience, therefore does not have any inner necessity, is always valid only for special cases and can anytime be refuted by opposite facts. On the contrary, the law is a logical relation between conceptual constructions; it is therefore deductible from upper [übergeordnete] laws and enables the derivation of lower laws; it has as such a logical necessity in concordance with its upper premises; it is not a mere statement of probability, but has a compelling, apodictic logical value once its premises are accepted”

“Hitherto our principal difficulty has arose from a want of proper supplies of money, and from the inefficacy of that which we obtained; but now there appears a scene opening which will introduce new embarrassments. The Congress have recommended to the different States to take upon themselves the furnishing certain species of supplies for our department. The recommendation falls far short of the general detail of the business, the difficulty of ad justing which, between the different agents as well as the different authorities from which they derive their appointments, I am very apprehensive will introduce some jarring interests, many improper disputes, as well as dangerous delays. Few persons, who have not a competent knowledge of this employment, can form any tolerable idea of the arrangements necessary to give despatch and success in discharging the duties of the office, or see the necessity for certain relations and dependencies. The great exertions which are frequently necessary to be made, require the whole machine to be moved by one common interest, and directed to one general end. How far the present measures, recommended to the different States, are calculated to promote these desirable purposes, I cannot pretend to say; but there appears to me such a maze, from the mixed modes adopted by some States, and about to be adopted by others, that I cannot see the channels, through which the business may be conducted, free from disorder and confusion.”

“Mr. Owen looked upon men through the spectacles of his own good-nature. He seldom took Lord Brougham's advice "to pick his men." He never acted on the maxim that the working class are as jealous of each other as the upper classes are of them. The resolution he displayed as a manufacturer he was wanting in as a founder of communities…. No leader ever took so little care as Mr, Owen in guarding his own reputation. He scarcely protested when others attached his name to schemes which were not his. The failure of Queenwood was not chargeable to him. When his advice was not followed he would say : "Well, gentlemen, I tell you what you ought to do. You differ from me. Carry out your own plans. Experience will show you who is right." When the affair went wrong then it was ascribed to him. Whatever failed under his name the public inferred failed through him. Mr. Owen was a general who never provided himself with a rear guard. While he was fighting in the front ranks priests might come up and cut off his commissariat. His own troops fell into pits against which he had warned them. Yet he would write his next dispatch without it occurring to him to mention his own defeat, and he would return to his camp without missing his army. Yet society is not so well served that it need hesitate to forgive the omissions of its generous friends. To Mr. Owen will be accorded the distinction of being a philosopher who devoted himself to founding a Science of Social Improvement and a philanthropist who gave his fortune to advance it. Association, which was but casual before his day, he converted into a policy and taught it as an art. He substituted Co-operation for coercion in the conduct ot industry and the willing co-operation of intelligence certain of its own reward, for sullen labour enforced by the necessity of subsistence, seldom to be relied on and never satisfied.”

“Our first necessity, if India is to survive and do her appointed work in the world, is that the youth of India should learn to think,—to think on all subjects, to think independently, fruitfully, going to the heart of things, not stopped by their surface, free of prejudgments, shearing sophism and prejudice asunder as with a sharp sword, smiting down obscurantism of all kinds as with the mace of Bhima. (…) When there is destruction, it is the form that perishes, not the spirit—for the world and its ways are forms of one Truth which appears in this material world in ever new bodies…. In India, the chosen land, [that Truth] is preserved; in the soul of India it sleeps expectant on that soul's awakening, the soul of India leonine, luminous, locked in the closed petals of the ancient lotus of love, strength and wisdom, not in her weak, soiled, transient and miserable externals. India alone can build the future of mankind. (…) Ancient or pre-Buddhistic Hinduism sought Him both in the world and outside it; it took its stand on the strength and beauty and joy of the Veda, unlike modern or post-Buddhistic Hinduism which is oppressed with Buddha's sense of universal sorrow and Shankara's sense of universal illusion,—Shankara who was the better able to destroy Buddhism because he was himself half a Buddhist. Ancient Hinduism aimed socially at our fulfilment in God in life, modern Hinduism at the escape from life to God. The more modern ideal is fruitful of a noble and ascetic spirituality, but has a chilling and hostile effect on social soundness and development; social life under its shadow stagnates for want of belief and delight, sraddha and ananda. If we are to make our society perfect and the nation is to live again, then we must revert to the earlier and fuller truth.”

“What has taken place is a shift of business from one manufacturer to another, and the announcements in the press as well as the general publicity of those manufacturers who have succeeded in increasing their business give, I think, the impression that this is true of the whole industry. If we could assume, for the sake of argument, that we will reach the point at which twenty-five million cars and trucks will be registered in the United States an assumption that from what we have accomplished so far is certainly perfectly reasonable then I think we could safely say that the replacement demand, plus the export demand which will increase for many years yet, plus the normal growth, would amount to something like four to four and one half million vehicles a year and would require the manufacture of a number of cars equal to or greater than has yet been produced in any year in the history of the industry…
I am sure that I do not need to elaborate what the automotive industry consists of, its influence on the prosperity of the United States, the influence that it has had in many other industries which contribute to its production necessities. General Motors is an important part of this great industry of ours and as my contribution to your visit with us I would like to tell you in a brief way something about General Motors; how we are thinking, what we are doing, and our ambitions for the future.”

“When, where, and how were you, Joseph Smith, first called? How old were you? and what were you qualifications? I was between fourteen and fifteen years of age. Had you been to college? No. Had you studied in any seminary of learning? No. Did you know how to read? Yes. How to write? Yes. Did you understand much about arithmetic? No. About grammar? No. Did you understand all the branches of education which are generally taught in our common schools? No. But yet you say the Lord called you when you were but fourteen or fifteen years of age? How did he call you? I will give you a brief history as it came from his own mouth. I have often heard him relate it. He was wrought upon by the Spirit of God, and felt the necessity of repenting of his sins and serving God. He retired from his father's house a little way, and bowed himself down in the wilderness, and called upon the name of the Lord. He was inexperienced, and in great anxiety and trouble of mind in regard to what church he should join. He had been solicited by many churches to join with them, and he was in great anxiety to know which was right. He pleaded with the Lord to give him wisdom on the subject; and while he was thus praying, he beheld a vision, and saw a light approaching him from the heavens; and as it came down and rested on the tops of the trees, it became more glorious; and as it surrounded him, his mind was immediately caught away from beholding surrounding objects. In this cloud of light he saw two glorious personages; and one, pointing to the other, said, "Behold my beloved son! hear ye him."”

“We are now approaching a social revolution, in which the old economic foundations of monogamy will disappear just as surely as those of its complement, prostitution. Monogamy arose through the concentration of considerable wealth in one hand — a man's hand — and from the endeavor to bequeath this wealth to the children of this man to the exclusion of all others. This necessitated monogamy on the woman's, but not on the man's part. Hence this monogamy of women in no way hindered open or secret polygamy of men. Now, the impending social revolution will reduce this whole care of inheritance to a minimum by changing at least the overwhelming part of permanent and inheritable wealth—the means of production—into social property. Since monogamy was caused by economic conditions, will it disappear when these causes are abolished?
One might reply, not without reason: not only will it not disappear, but it will rather be perfectly realized. For with the transformation of the means of production into collective property, wagelabor will also disappear, and with it the proletariat and the necessity for a certain, statistically ascertainable number of women to surrender for money. Prostitution disappears and monogamy, instead of going out of existence, at last becomes a reality—for men also.
At all events, the situation will be very much changed for men. But also that of women, and of all women, will be considerably altered. With the transformation of the means of production into collective property the monogamous family ceases to be the economic unit of society. The private household changes to a social industry. The care and education of children become? a public matter. Society cares equally well for all children, legal or illegal. This removes the care about the "consequences" which now forms the essential social factor—moral and economic—hindering a girl to surrender unconditionally to the beloved man. Will not this be sufficient cause for a gradual rise of a more unconventional intercourse of the sexes and a more lenient public opinion regarding virgin honor and female shame? And finally, did we not see that in the modern world monogamy and prostitution, though antitheses, are inseparable and poles of the same social condition? Can prostitution disappear without engulfing at the same time monogamy?”

“One of the most natural of reactions during the war was intolerance. But the inevitable disregard for the opinions and feelings of minorities is none the less a disturbing product of war psychology. The slow and difficult advances which tolerance and liberalism have made through long periods of development are dissipated almost in a night when the necessary war-time habits of thought hold the minds of the people. The necessity for a common purpose and a united intellectual front becomes paramount to everything else. But when the need for such a solidarity is past there should be a quick and generous readiness to revert to the old and normal habits of thought. There should be an intellectual demobilization as well as a military demobilization. Progress depends very largely on the encouragement of variety. Whatever tends to standardize the community, to establish fixed and rigid modes of thought, tends to fossilize society. If we all believed the same thing and thought the same thoughts and applied the same valuations to all the occurrences about us, we should reach a state of equilibrium closely akin to an intellectual and spiritual paralysis. It is the ferment of ideas, the clash of disagreeing judgments, the privilege of the individual to develop his own thoughts and shape his own character, that makes progress possible. It is not possible to learn much from those who uniformly agree with us. But many useful things are learned from those who disagree with us; and even when we can gain nothing our differences are likely to do us no harm. In this period of after-war rigidity, suspicion, and intolerance our own country has not been exempt from unfortunate experiences. Thanks to our comparative isolation, we have known less of the international frictions and rivalries than some other countries less fortunately situated. But among some of the varying racial, religious, and social groups of our people there have been manifestations of an intolerance of opinion, a narrowness to outlook, a fixity of judgment, against which we may well be warned. It is not easy to conceive of anything that would be more unfortunate in a community based upon the ideals of which Americans boast than any considerable development of intolerance as regards religion. To a great extent this country owes its beginnings to the determination of our hardy ancestors to maintain complete freedom in religion. Instead of a state church we have decreed that every citizen shall be free to follow the dictates of his own conscience as to his religious beliefs and affiliations. Under that guaranty we have erected a system which certainly is justified by its fruits. Under no other could we have dared to invite the peoples of all countries and creeds to come here and unite with us in creating the State of which we are all citizens.”

“I am glad to be able to fortify my position on this point by the great name and ability of Theophilus Parsons, of the Harvard Law School. In discussing the necessity of negro suffrage at a recent public meeting in Boston, he says: "Some of the Southern States have among their statutes a law prohibiting the education of a colored man under a heavy penalty. The whole world calls this most inhuman, most infamous. And shall we say to the whites of those States, 'We give you complete and exclusive power of legislating about the education of the blacks; but beware, for if you lift them by education from their present condition, you do it under the penalty of forfeiting and losing your supremacy?' Will not slavery, with nearly all its evils, and with none of its compensation, come back at once? Not under its own detested name; it will call itself apprenticeship; it will put on the disguise of laws to prevent pauperism, by providing that every colored man who does not work in some prescribed way shall be arrested, and placed at the disposal of the authorities; or it will do its work by means of laws regulating wages and labor. However it be done, one thing is certain: if we take from the slaves all the protection and defence they found in slavery, and withhold from them all power of self-protection and self-defence, the race must perish, and we shall be their destroyers."”

Aspettate fino alla sera prima del giorno fissato per la rappresentazione. Nessuna cosa eccita più l'estro come la necessità, la presenza d'un copista, che aspetta il vostro lavoro e la ressa d'un impresario in angustie, che si strappa a ciocche i capelli.
