This question refers to the following information.
"The Italian nation has been at last united in our own days, and we all rejoiced in its union. Yet we may be allowed to doubt whether the union was not a little too speedy and a little too thorough. It is surely carrying unity too far to wipe out all traces of the independent being, for most purposes to wipe out the very name, of such a land as Sicily. It jars on our feelings to find that, while Ireland at least forms part of the royal style of its sovereign, Sicily is no longer even a geographical expression. The island realm of Roger has sunk to be seven provinces of the kingdom on the mainland. And there is another result of Italian unity, a result in which we may rejoice without drawbacks, but which still has somewhat of sadness about it as finally ending that great phase of the history of Europe with which we have throughout been dealing. Never were ties with the past so fully snapped as when the army of Italy entered liberated Rome. Of all novelties in European history the greatest was when Rome became the centre of a dominion with acknowledged metes and bounds, the head in short of a local Italian kingdom. "Rome the capital of Italy" was a formula which might well gladden our hearts; but it was a formula which formally swept away the œcumenical position, the œcumenical traditions, of Rome&….
But the kingdom of Italy is not an appendage to Rome; Rome is the head of the kingdom. The whole is greater than its part; Rome, by her own free will and by the free will of Italy, has become less than Italy. By becoming the willing head of an Italian kingdom she has formally cast aside her Imperial traditions as they were not cast aside when brute force made her the head of a French department."

Read the following excerpt.
If civilized education developed in every child its natural inclinations, we should see nearly all rich children enamored of various very plebeian occupations, such as that of the mason, the carpenter, the smith, the saddler. I have instanced Louis the XVI, who loved the trade of locksmith; an Infanta of Spain preferred that of shoemaker; a certain king of Denmark gratified himself by manufacturing syringes; the former king of Naples loved to sell the fish he had caught in the market-place himself; the prince of Parma, whom Condillac had trained in metaphysical subtitles, in the understanding of intuition, of cognition, had no taste but for the occupation of church-warden and lay-brother.
The great majority of wealthy children would follow these plebeian tastes, if civilized education did not oppose the development of them; and if the filthiness of the workshops and the coarseness of the workmen did not arouse a repugnance stronger than the attraction. What child of a prince is there who has no taste for one of the four occupations I have just mentioned, that of mason, carpenter, smith, saddler, and who would not advance in them if he beheld from an early age the work carried on in blight workshops, by refined people, who would always arrange a miniature workshop for children, with little implements and light labor?

The situation is critical in the extreme. In fact it is now absolutely clear that to delay the uprising would be fatal.
With all my might I urge comrades to realize that everything now hangs by a thread; that we are confronted by problems which are not to be solved by conferences or congresses (even congresses of Soviets), but exclusively by peoples, by the masses, by the struggle of the armed people. …
Who must take power? That is not important at present. Let the Revolutionary Military Committee do it, or "some other institution" which will declare that it will relinquish power only to the true representatives of the interests of the people, the interests of the army, the interests of the peasants, the interests of the starving.
All districts, all regiments, all forces must be mobilized at once and must immediately send their delegations to the Revolutionary Military Committee and to the Central Committee of the Bolsheviks with the insistent demand that under no circumstances should power be left in the hands of Kerensky [and his colleagues], … not under any circumstances; the matter must be decided without fail this very evening, or this very night.

Read the following governmental report.
Of the 450 sick persons whom the inhabitants were unable to relieve, 200 were turned out, and these we saw die one by one as they lay on the roadside. A large number still remain, and to each of them it is only possible to dole out the least scrap of bread. We only give bread to those who would otherwise die. The staple dish here consists of mice, which the inhabitants hunt, so desperate are they from hunger. They devour roots which the animals cannot eat; one can, in fact, not put into words the things one sees. . . . This narrative, far from exaggerating, rather understates the horror of the case, for it does not record the hundredth part of the misery in this district. Those who have not witnessed it with their own eyes cannot imagine how great it is. Not a day passes but at least 200 people die of famine in the two provinces. We certify to having ourselves seen herds, not of cattle, but of men and women, wandering about the fields between Rheims and Rhétel, turning up the earth like pigs to find a few roots; and as they can only find rotten ones, and not half enough of them, they become so weak that they have not strength left to seek food. The parish priest at Boult, whose letter we enclose, tells us he has buried three of his parishioners who died of hunger. The rest subsisted on chopped straw mixed with earth, of which they composed a food which cannot be called bread. Other persons in the same place lived on the bodies of animals which had died of disease, and which the curé, otherwise unable to help his people, allowed them to roast at the presbytery fire.

Paris has a short memory. If I remain longer doing nothing, I am lost. In this great Babylon one reputation quickly succeeds another. After I have been seen three times at the theatre, I shall not be looked at again. I shall therefore not go very frequently. (diary, 1798)

The presence of a general is necessary; he is the head, he is the all in all of an army. It was not the Roman army that conquered Gaul, it was Caesar, it was not the Carthaginians that made the armies of the Roman republic tremble at the very gates of Rome, it was Hannibal. (diary, 1801)
My power proceeds from my reputation, and my reputation from the victories I have won. My power would fall if I were not to support it with more glory and more victories. Conquest has made me what I am; only conquest can maintain me. (diary, 1802)
The revolution in France is over and now there is only one party in France and I shall never allow the newspapers to say anything contrary to my interests. They may publish a few little articles with just a bit of poison in them, but one fine day I shall shut their mouths forever. (diary, 1805)

The following account of the Paris Exposition of 1889.
"The opportunities to study the natural history of man in Paris during the Exposition, and especially in August, when the great Congresses and the French Association held their sessions, were unparalleled in the history of anthropology. At any time the French capital affords rare advantages to the anthropologist. The Musée and Laboratoire Broca, the anthropometric operations of Bertillon in the Palais de Justice, the courses of lectures in the école d'Anthropologie, the collections in the Jardin de Plantes, the facilities for original work in the écoles de Medicine, and the hospitals give to the comparative anatomist and biologist abundant employment."
Otis T. Mason, American ethnologist and curator, 1889
The opportunities described in the text can be attributed to
A. the stability brought to France by the Third Republic
B. France's preparation for the upcoming Franco-Prussian War during the Second Empire

The following quote is from Voltaire in response to the 1755 Lisbon earthquake.
My dear sir, nature is very cruel. One would find it hard to imagine how the laws of movement cause such frightful disasters in the best of possible worlds. A hundred thousand ants, our fellows, crushed all at once in our ant-hill, and half of them perishing, no doubt in unspeakable agony, beneath the wreckage from which they cannot be drawn. Families ruined all over Europe, the fortune of a hundred businessmen, your compatriots, swallowed up in the ruins of Lisbon. What a wretched gamble is the game of human life! What will the preachers say, especially if the palace of the Inquisition is still standing? I flatter myself that at least the reverend father inquisitors have been crushed like others. That ought to teach men not to persecute each other, for while a few holy scoundrels burn a few fanatics, the earth swallows up one and all.
—Voltaire, in a letter, 1755

This question refers to the following information.
"In 1500 that work appeared which Erasmus had written after his misfortune at Dover, and had dedicated to Mountjoy, the Adagiorum Collectanea. It was a collection of about eight hundred proverbial sayings drawn from the Latin authors of antiquity and elucidated for the use of those who aspired to write an elegant Latin style. In the dedication Erasmus pointed out the profit an author may derive, both in ornamenting his style and in strengthening his argumentation, from having at his disposal a good supply of sentences hallowed by their antiquity. He proposes to offer such a help to his readers. What he actually gave was much more. He familiarized a much wider circle than the earlier humanists had reached with the spirit of antiquity.
Until this time the humanists had, to some extent, monopolized the treasures of classic culture, in order to parade their knowledge of which the multitude remained destitute, and so to become strange prodigies of learning and elegance. With his irresistible need of teaching and his sincere love for humanity and its general culture, Erasmus introduced the classic spirit, in so far as it could be reflected in the soul of a sixteenth-century Christian, among the people. Not he alone; but none more extensively and more effectively. Not among all the people, it is true, for by writing in Latin he limited his direct influence to the educated classes, which in those days were the upper classes.
Erasmus made current the classic spirit. Humanism ceased to be the exclusive privilege of a few. According to Beatus Rhenanus he had been reproached by some humanists, when about to publish the Adagia, for divulging the mysteries of their craft. But he desired that the book of antiquity should be open to all."

"XI. As the present sciences are useless for the discovery of effects, so the present system of logic is useless for the discovery of the sciences.
XIX. There are and can exist but two ways of investigating and discovering truth. The one hurries on rapidly from the senses and particulars to the most general axioms, and from them, as principles and their supposed indisputable truth, derives and discovers the intermediate axioms. This is the way now in use. The other constructs its axioms from the senses and particulars, by ascending continually and gradually, till it finally arrives at the most general axioms, which is the true but unattempted way.
XXII. Each of these two ways begins from the senses and particulars, and ends in the greatest generalities&…
XXXVI. We have but one simple method of delivering our sentiments, namely, we must bring men to particulars and their regular series and order, and they must for a while renounce their notions, and begin to form an acquaintance with things."

This question refers to the following information.
Apart from the desire to produce beautiful things, the leading passion of my life has been and is hatred of modern civilization. What shall I say of it now, when the words are put into my mouth, my hope of its destruction—what shall I say of its supplanting by Socialism?
What shall I say concerning its mastery of and its waste of mechanical power, its commonwealth so poor, its enemies of the commonwealth so rich, its stupendous organization—for the misery of life! Its contempt of simple pleasures which everyone could enjoy but for its folly? Its eyeless vulgarity which has destroyed art, the one certain solace of labor? All this I felt then as now, but I did not know why it was so. The hope of the past times was gone, the struggles of mankind for many ages had produced nothing but this sordid, aimless, ugly confusion; the immediate future seemed to me likely to intensify all the present evils by sweeping away the last survivals of the days before the dull squalor of civilization had settled down on the world.
This was a bad lookout indeed, and, if I may mention myself as a personality and not as a mere type, especially so to a man of my disposition, careless of metaphysics and religion, as well as of scientific analysis, but with a deep love of the earth and the life on it, and a passion for the history of the past of mankind.

Read the the following petition to answer questions.
The Scribbling-Machines have thrown thousands of your petitioners out of employ, whereby they are brought into great distress, and are not able to procure a maintenance for their families, and deprived them of the opportunity of bringing up their children to labour. … The number of Scribbling-Machines extending about seventeen miles south-west of Leeds exceed all belief, being no less than one hundred and seventy! And as each machine will do as much work in twelve hours, as ten men can in that time do by hand, … [And, as the machines do] as much work in one day as would otherwise employ twenty men, … [a] full four thousand men are left to shift for a living how they can, and must of course fall to the Parish, if not timely relieved. … How are those men, thus thrown out of employ to provide for their families; and what are they to put their children apprentice to, that the rising generation may have something to keep them at work, in order that they may not be like vagabonds strolling about in idleness? … Many more evils we could enumerate, but we would hope, that the sensible part of mankind, who are not biased by interest, must see the dreadful tendency of their continuance; a depopulation must be the consequence; trade being then lost, the landed interest will have no other satisfaction but that of being last devoured.

For a long time, educated Germans answered it in the positive, initially by laying claim to a special German mission, then, after the collapse of 1945, by criticizing Germany's deviation from the West. Today, the negative view is predominant. Germany did not, according to the now prevailing opinion, differ from the great European nations to an extent that would justify speaking of a "unique German path." And, in any case, no country on earth ever took what can be described as the "normal path."

The passage below is written by John Calvin.
If we need to be recalled to the origin of election, to prove that we obtain salvation from no other source than the mere goodness of God, they who desire to extinguish this principle, do all they can to obscure what ought to be magnificently and loudly celebrated, and to pluck up humility by the roots. In ascribing the salvation of the remnant of the people to the election of grace, Paul clearly testifies, that it is then only known that God saves whom upon which there can be no claim. They who shut the gates to prevent anyone from presuming to approach and taste this doctrine, do no less injury to man than to God; for nothing else will be sufficient to produce in us suitable humility, or to impress us with a due sense of our great obligations to God. Nor is there any other basis for solid confidence, even according to the authority of Christ, who, to deliver us from all fear, and render us invincible amidst so many dangers, snares, and deadly conflicts, promises to preserve in safety all whom the Father has committed to His care.
