Essays: Moral, Political, and Literary. David Hume

new occur, he may supply it from his invention; nor will the difference be very apparent between his elaborate and his extemporary compositions. The mind naturally continues with the same impetus or force, which it has acquired by its motion; as a vessel, once impelled by the oars, carries on its course for some time, when the original impulse is suspended.

      I shall conclude this subject with observing, that, even though our modern orators should not elevate their stile or aspire to a rivalship with the ancient; yet is there, in most of their speeches, a material defect, which they might correct, without departing from that composed air of argument and reasoning, to which they limit their ambition. Their great affectation of extemporary discourses has made them reject all order and method, which seems so requisite to argument, and without which it is scarcely possible to produce an entire conviction on the mind. It is not, that one would recommend many divisions in a public discourse, unless the subject very evidently offer them: But it is easy, without this formality, to observe a method, and make that method conspicuous to the hearers, who will be infinitely pleased to see the arguments rise naturally from one another, and will retain a more thorough persuasion, than can arise from the strongest reasons, which are thrown together in confusion.

ESSAY XIV

       OF THE RISE AND PROGRESS OF THE ARTS AND SCIENCES

      NOTHING requires greater nicety,° in our enquiries concerning human affairs, than to distinguish exactly what is owing to chance, and what proceeds from causes; nor is there any subject, in which an author is more liable to deceive himself by false subtilties and refinements. To say, that any event is derived from chance, cuts short all farther enquiry concerning it, and leaves the writer in the same state of ignorance with the rest of mankind. But when the event is supposed to proceed from certain and stable causes, he may then display his ingenuity, in assigning these causes; and as a man of any subtilty can never be at a loss in this particular, he has thereby an opportunity of swelling his volumes, and discovering his profound knowledge, in observing what escapes the vulgar and ignorant.

      

      The distinguishing between chance and causes must depend upon every particular man’s sagacity, in considering every particular incident. But, if I were to assign any general rule to help us in applying this distinction, it would be the following, What depends upon a few persons is, in a great measure, to be ascribed to chance, or secret and unknown causes: What arises from a great number, may often be accounted for by determinate and known causes.

      Two natural reasons may be assigned for this rule. First, If you suppose a dye to have any biass, however small, to a particular side, this biass, though, perhaps, it may not appear in a few throws, will certainly prevail in a great number, and will cast the balance entirely to that side. In like manner, when any causes beget a particular inclination or passion, at a certain time, and among a certain people; though many individuals may escape the contagion, and be ruled by passions peculiar to themselves; yet the multitude will certainly be seized by the common affection, and be governed by it in all their actions.

      Secondly, Those principles or causes, which are fitted to operate on a multitude, are always of a grosser and more stubborn nature, less subject to accidents, and less influenced by whim and private fancy, than those which operate on a few only. The latter are commonly so delicate and refined, that the smallest incident in the health, education, or fortune of a particular person, is sufficient to divert their course, and retard their operation; nor is it possible to reduce them to any general maxims or observations. Their influence at one time will never assure us concerning their influence at another; even though all the general circumstances should be the same in both cases.

      To judge by this rule, the domestic and the gradual revolutions of a state must be a more proper subject of reasoning and observation, than the foreign and the violent, which are commonly produced by single persons, and are more influenced by whim, folly, or caprice, than by general passions and interests. The depression of the lords, and rise of the commons in ENGLAND, after the statutes of alienation and the encrease of trade and industry, are more easily accounted for by general principles, than the depression of the SPANISH, and rise of the FRENCH monarchy, after the death of CHARLES QUINT.¹ Had HARRY IV. Cardinal RICHLIEU, and LOUIS XIV. been SPANIARDS; and PHILIP II. III. and IV. and CHARLES II. been FRENCHMEN, the history of these two nations had been entirely reversed.²

      For the same reason, it is more easy to account for the rise and progress of commerce in any kingdom, than for that of learning; and a state, which should apply itself to the encouragement of the one, would be more assured of success, than one which should cultivate the other. Avarice, or the desire of gain, is an universal passion, which operates at all times, in all places, and upon all persons: But curiosity, or the love of knowledge, has a very limited influence, and requires youth, leisure, education, genius, and example, to make it govern any person. You will never want booksellers, while there are buyers of books: But there may frequently be readers where there are no authors. Multitudes of people, necessity and liberty, have begotten commerce in HOLLAND: But study and application have scarcely produced any eminent writers.

      We may, therefore, conclude, that there is no subject, in which we must proceed with more caution, than in tracing the history of the arts and sciences; lest we assign causes which never existed, and reduce what is merely contingent to stable and universal principles. Those who cultivate the sciences in any state, are always few in number: The passion, which governs them, limited: Their taste and judgment delicate and easily perverted: And their application disturbed with the smallest accident. Chance, therefore, or secret and unknown causes, must have a great influence on the rise and progress of all the refined arts.

      But there is a reason, which induces me not to ascribe the matter altogether to chance. Though the persons, who cultivate the sciences with such astonishing success, as to attract the admiration of posterity, be always few, in all nations and all ages; it is impossible but a share of the same spirit and genius must be antecedently diffused throughout the people among whom they arise, in order to produce, form, and cultivate, from their earliest infancy, the taste and judgment of those eminent writers. The mass cannot be altogether insipid, from which such refined spirits are extracted. There is a God within us, says OVID, who breathes that divine fire, by which we are animated.³ Poets, in all ages, have advanced this claim to inspiration. There is not, however, any thing supernatural in the case. Their fire is not kindled from heaven. It only runs along the earth; is caught from one breast to another; and burns brightest, where the materials are best prepared, and most happily disposed. The question, therefore, concerning the rise and progress of the arts and sciences, is not altogether a question concerning the taste, genius, and spirit of a few, but concerning those of a whole people; and may, therefore, be accounted for, in some measure, by general causes and principles. I grant, that a man, who should enquire, why such a particular poet, as HOMER,⁴ for instance, existed, at such a place, in such a time, would throw himself headlong into chimæra,° and could never treat of such a subject, without a multitude of false subtilties and refinements. He might as well pretend to give a reason, why such particular generals, as FABIUS and SCIPIO, lived in ROME at such a time, and why FABIUS came into the world before SCIPIO.⁵ For such incidents as these, no other reason can be given than that of HORACE:

      Scit genius, natale comes, qui temperat astrum,

      Naturæ Deus humanæ, mortalis in unum—

      —Quodque caput, vultu mutabilis, albus & ater.⁶

      But I am persuaded, that in many cases good reasons might be given, why such a nation is more polite and learned, at a particular time, than any of its neighbours. At least, this is so curious a subject, that it were a pity to abandon it entirely, before we have found whether it be susceptible of reasoning, and can be reduced to any general principles.^a
