the amount of marketable things, for which an article can be exchanged. It is also well settled that demand determines the market value; but they assert, again, or at least seem to imply, that value and cost are synonymous. They also generally imply, by the mode of using the term cost, that it is some definite, fixed quantity. This use of language throws great obscurity on their speculations on this subject, since the cost of producing an article varies from week to week, by the variation of the price of the materials, and the wages; and the same kind and quality of articles will, at the same time, cost one producer more than another. The proposition that cost regulates value, is laid down by the writers with great solemnity, and inculcated at great length. It is a subject on which there certainly is a great deal of unprofitable prolixity in the books; for what argument or illustration is necessary to establish the proposition, that men will not continue long to produce an article by which they lose money? The proposition seems to stand in quite as great need of an apology for stating it, as of a disquisition to explain or support it.

Mr. Ricardo's theory of rent is an ingredient in recent treatises on political economy. The result of his theory is, that, if there was no difference in the productive qualities of all the parts of the whole territory of a nation, there would be no such thing as rent. The conclusion of his theory is, that every additional bushel of corn raised in a country costs more than the preceding. Very few persons will probably assent to the first of these two propositions, and the last is absurd as applied to the U. States and many other countries. He doubtless had England in his view in framing his theory; but Mr. Lowe denies its accuracy in respect to England, as a matter of fact, upon the statement of cultivators themselves. Mr. M'Culloch goes into a consideration of the effect of the fluctuations of wages upon the cost of commodities, in order to establish the proposition that if the cost of the production of two articles depends upon the use of machinery, and the machinery for one is of short duration, and that for the other of long, then a rise in wages will affect the cost of the products of the transient machinery, more than that of the other. He discusses this proposition quite elaborately, for the purpose, apparently, of showing that an increase of wages will, in effect, result in a comparative enhancement of the profits of the producer who

uses the durable machinery; for he has only to pay the advanced wages for working his machine, whereas the other must pay both for replacing and for working his. This is rather an obscure and nice distinction, and, to be just, requires that the price of the durable machine shall not have risen in value, in consequence of the increase of the expense of building a new one, by reason of the rise of wages; whereas it is according to common experience to suppose that it would rise in value, in which case Mr. M'Culloch's theory vanishes.

Passing over what relates to consumption (q. v.), the above are some of the leading doctrines and theories of what is called the science of political economy, as taught by recent writers in France and England; a science of which Adam Smith is said, by its professors, to be the founder. Perhaps no study of the day, which bears the name of science, presents more vague theory, grave, mysterious empiricism, dull prolixity, inconsequential arguments, gratuitous assumptions, jejune discussions, and elaborate triviality. There are many useful truths, which pass under the name of political economy; but a large proportion of the treatises, from that of Adam Smith downwards, by the disciples of his school, seem to bear the same relation to an intelligible practical developement of the causes and phenomena of national growth, wealth and decline, that alchemy does to modern chemistry.-For other branches of political economy, see the articles Banks, Bounties, Circulating Medium, Commerce, Consumption, Corn Laws, Credit, Debtor and Creditor, Direct Tax, Laborers, Labor-saving Machines, Lotteries, Mercantile System, Money, Monopoly, Literary Property, Patent, Physiocratical System.

(Columbia, 1826); Cardozo's Notes on Polit. Econ.(Charleston, 1826); Thoughts on Polit. Econ. by D. Raymond (Baltimore, 1820). POLITICAL INSTITUTIONS. The origin of political societies and institutions has been a frequent subject of disquisition. Like many other things, they are supported from an instinctive feeling of their necessity, though their origin and true principles may not be correctly understood. The universal feeling of their necessity has induced some persons to compare political institutions to languages; both, they say, are essential to the existence of mankind; both exist from time immemorial, and neither can be changed at will;-a comparison which tends, like other partial analogies, to lead the inquirer into error. The theories of the origin of the state may be comprised under two heads-those which make authority the starting point, and those which seek it in equality. Those who support the former principle are again divided; some recur at once to God, and say, that he united all power in the hands of the father of the family, who, therefore, at first, had the priestly and princely, as well as the paternal authority; and it was only in later times that these functions became separated; but it is idle, in scientific speculation, to refer positive institutions to God. He

implanted the principles of every thing good, but we are not to take for granted a direct interference, on his part, in their application. Other advocates of authority place the origin of political institutions in force. Mr. von Haller started this idea anew. (See the article Haller, Charles Louis von.) We have already spoken of the mistake of laying much stress upon the supposed origin of bodies politic, in the article Estates (vol. iv, note on p. 585). What did Mozart, in composing his Requiem, care for the origin of music? or Ariosto, or Milton, for the origin of languages? Political institutions may have originated in a variety of ways, from force, compact, reverence, &c.; and they actually have, as history shows us. But their accidental origin does not show the principle which lies at their foundation, holds them together, and is understood more clearly with the improvement of the social order. The accidental origin of the hut of the savage does not teach us the principles of architecture. These are gradually unfolded, in proportion as the art advances. The principle which lies at the basis of all political union we hold to be the idea of the just, as that of the good is the foundation of morals, and that of the beautiful of the fine arts. The idea of the just, again, in politics is but a modification of the idea of equality. This is the animating principle of all political societies, whatever may have been their origin, and is invariably developed in the progress of society, as the flower is the product of the perfect plant. The idea of force declines as this principle is unfolded. We might add, that the idea of the just is at least as ancient as that of paternal authority; because, as soon as two individuals are placed together, the idea of equal rights arises, the idea of "doing as one would be done by." Still more is this the case in a family, because as soon as there are several children, parents as well as children feel that it is not right to prohibit to one of the children what, in the same case, would be allowed to another. That children obey their parents originally from a mere feeling of inferiority, may be allowed; but states consist of men, and little would the remembrance of former inferiority avail for the maintenance of social order. The idea of the state and of law (for both go hand in hand, and the essence of law is equality, even where it establishes differences and privileges) has a much surer foundation in the idea of the just, which is as primitive an idea as that of the good. Whether, therefore, all bodies politic were

originally founded upon the social compact or not, this social compact is the fundamental idea of all, and that to which all strive in the progress of their developement, (See our article Estates for the various stages of political government; see, also, Constitution, and Sovereignty.)

POLITICS, in its widest extent, is both the science and the art of government, or the science whose subject is the regulation of man, in all his relations as the member of a state, and the application of this science. In other words, it is the theory and the practice of obtaining the ends of civil society as perfectly as possible. In common parlance, we understand by the politics of a country the course of its government, more particularly as respects its relations with foreign nations; and the more important these relations are (as, for instance, in European states, which exert so powerful an influence on each other), the more prominent is the place which they hold in the ideas conveyed by the word; whilst in a country like the U. States, whose relations to foreign countries are comparatively unimportant, the word, in common usage, is naturally more confined to the principles and operation of the internal government. Politics, therefore, extends to every thing which is the subject of positive laws; for it is by means of these that the purposes of a state or civil union are effected. The political relations of men have therefore always been the en grossing subject of history. (See the definition of history, at the beginning of the article on it.) As the idea of politics depends upon that of state, a definition of the latter will easily mark out the whole province of the political sciences. By state we understand a society formed by men, with the view of better obtaining the ends of life by a union of powers and mutual assistance. This idea of state is the basis of a class of sciences, and gives them as distinct a character as belongs to the various classes of historical, philosophical, theological, medical, &c., sciences. The political sciences are divisible into the abstract, or purely philosophical, and the historical and practical. This, however, is not the best order for studying them. The following order may, perhaps, be adapted to the wants of the scientific student:-1. Natural law, which treats of the rights and duties of men in the absence of all positive regulations. As the idea of law and the mutual obligations of men is closely connected with that of the state or government, the philosophy of government enters, in some degree, into this science, so

that the various views of the origin of governments, whether they are to be considered as founded essentially on compact or force, or as having a divine origin, &c., fall under natural law. The subject of natural law is treated at considerable length in the article on that subject, in our ninth volume, to which we refer the reader; also to the article Haller, as he gives a peculiar turn to the old notion of divine right.-For the various theories of natural law, see the works of Hugo Grotius, De Jure Belli et Pacis (Paris, 1625), which belongs, however, more properly to the practical law of nations; Puffendorf, Elementa Jurispru dentiæ universalis; Wolf, Jus Naturæ, Methodo scientifica pertractatum (8 vols., Halle, 1740-49, 4to.); Montesquieu's Esprit des Lois; Rutherforth's Institutes of Natural Law; Ferguson on Civil Society; also the works on government by Filmer, Locke, Mackenzie, Algernon Sidney, Hume, Milton, and a host of modern writers.-2. Though the theory of government falls, in some degree, under natural law, yet the full treatment of so extended a subject gives rise to a separate branch of science, which we might call abstract or theoretical politics. This department treats of the object of the state, and the relation between the state and the individual; of the right to prescribe laws, and to punish; of fundamental laws and compacts; of the various forms of governments-monarchies and republics, aristocracies, democracies, representative systems, &c.; of the division of powers, legislative, judiciary, executive; of the means of obtaining the true ends of the state; of the relations between different political societies, &c.; and of the whole subject of criminal law (q. v.), philosophically considered. Among the most important authors on these subjects are Plato, Aristotle, Cicero, among the ancients; Macchiavelli, Il Principe, with Frederic the Great's Antimacchiavelli (1741), and that by Jakob (1794); Hubert Languet (under the assumed name of Stephanus Junius Brutus), Vindicia contra Tyrannos (Soleure, 1577); Mariana, De Rege et Regis Institutione (see Mariana); Hobbes, De Cive, and Leviathan, seu de Materia, Forma et Potestate Civitatis (see Hobbes); Locke, Two Treatises of Government (see Locke); Rousseau, Contrat Social; Chr. von Wolf, De Jure Civitatis (Halle, 1748); Aug. Schlözer, Allgemeines Staatstrecht und Staatsverfassungslehre (Göttingen, 1793); Von Haller (q. v.); Zacharia, Vierzig Bücher vom Staate (Tubingen, 1820, et seq.); Salmasius, Defensio pro Carolo I

and Milton's answer to him, Defensio pro Populo Anglicano; and Milton's Tenure of Kings and Magistrates, his Ready and Easy Way to establish a Free Commonwealth. Among the writers who have treated criminal law philosophically are Beccaria, Dei Delitti e delle Pene (Naples, 1764); Feuerbach, Revision der Grundsätze und Grundbegriffe des positiven peinlichen Rechts (2 vols., Erfurth, 1799), and his Lehrbuch des peinlichen Rechts (9th ed., Giessen, 1820); Grolman (q. v.), Tittman, Henke.-3. Political economy, which treats of the resources of national wealth, and the circumstances which affect it advantageously and disadvantageously. (See Political Economy.) The Germans give the name of national economy to what is generally comprised, with us, under political economy. Under state economy they include the management of the finances, and the regulations by which the government influences the wealth of the state. Under this latter branch, they treat of taxes, monopolies, loans, imports, exports, &c. -4 Science of police. (See Police.)-5. Practical politics, or the art of administering the government of states, both in regard to their internal and external relations. This branch tests the principles of political institutions, whether liberal or despotic, whether advocated by the holy alliance or by the friends of freedom.-6. History of politics. This traces the variety of civil governments; the causes of their rise and decay; how one grew out of the other; how they underwent fundamental changes, from the patriarchal form, in which religious institutions, civil government and family relations were rudely mixed, to the theocratic, in which the two former were blended; to military monarchies, after the separation of the military power from the priesthood; to democracies or aristocratic republics; to feudalism; to aristocratic constitutional monarchies; to representative aristocratico-democratic governments; and, at last, to democratic representative governments. The enumeration of the works necessary to the student of this branch, would far exceed our limits.-7. History of the European and American systems of states, as forming each a family of members under constant and intimate mutual influence. In as far as the relations of the members of these families can be learned from treaties of peace, &c., there exist very valuable materials-collections of documents by Du Mont, Rousset, Wenk, Von Martens, Koch, Schöll, Isambert, &c. The first attempt to treat this branch systematically was by J. Jac. Schmauss, in his

Introduction to Politics (in German), and commentaries on the Corpus Juris Gentium Academici (2 vols., Leipsic, 1741), edited by him. Koch wrote an Abrégé de l'Histoire des Traités de Paix entre les Puissances de l'Europe depuis la Paix de Westphalie (4 vols., Basil, 1796; a new edition in 15 vols., by Fr. Schöll, Paris, 1817). George Fr. von Martens wrote a Sketch of a Diplomatic History of the European Political Negotiations and Treaties, from the End of the fifteenth Century to the Peace of Amiens (in German, Berlin, 1807). Heeren wrote a Manual of the History of the European System of States (fourth edition, Göttingen, 1822); and Pölitz, Political Sciences (3d vol.); both in German.

8. Statistics, or a knowledge of the actual condition, resources, &c. of states. The term was first used by the Germans.-9. Positive, public and constitutional law This branch gives a scientific representation of the fundamental laws and constitutions of the various European and American states. Materials for this branch are found in Lacroix, Constitutions des principaux États de l'Europe et des États"Unis de l'Amerique (third edition, Paris, 1802); George Fr. von Marten's Collection of the most Important Fundamental Laws (in German); Pölitz, the Constitutions of the European States, during the twenty-five last Years (4 vols., Leipsic, 1817–1825, in German); Lüder's Diplomatic Archives for Europe (3 vols., Leipsic, 1819-1823, in German); Archives Diplomatiques pour l'Histoire du Temps et des Etats (6 vols., Stuttgard, 1821— 1825); and its continuation-Neueste Staatsacten und Urkunden (11 vols., Stuttg., 1825 seq.); Dufau, Duvergier and Guadet, Collection des Constitutions, Chartes et Lois fondamentales des Peuples de l'Europe et des deux Amériques (6 vols., Paris, 1821–23); Alb. Fritot, Science du Publiciste (11 vols., Paris, 1820—1823).—10. Practical law of nations, containing the scientific exposition of the principles adopted by modern civilized nations for the regulation of their mutual relations in peace and in war. To this belong the rights and duties of neutrals and belligerents, the rules relating to prizes (see Prize), prisoners, blockade, conquest (q. v.), &c. The rules of national law are not drawn up in a code, but are merely the principles which have developed themselves within the last 300 years. (See Nations, Law of.) J. Jac. Moser was the first who treated the practical law of nations separately from the theoretical, in his Attempt at a Sketch of the modern Euro

pean Law of Nations in Times of Peace and War (in German, 10 vols., Frankfort on the Maine, 1777). See, also, Vattel, Le Droit des Gens (3 vols., recent edition, Paris, 1820); George Fr. von Martens, Précis du Droit des Gens moderne de l'Europe; and Charles Martens, Causes célèbres du Droit des Gens. The Germans have numerous recent works in this branch of science.-11. Diplomacy. (See Diplomacy.-12. Political practice embraces whatever is necessary for the conduct of public affairs. In some European governments, in which all business is transacted by means of writings drawn up with various formalities, the wording, &c. of these writings forms a subject of study, and various works have been written on the chancery style, so called; and in all governments, the study of a diplomatic style, and of the mode of transacting diplomatic business, belongs to it. See Cours de Style Diplomatique (2 vols., Dresden, 1823). The knowledge of parliamentary rules, the duties of committees, and all the forms usual in the administration of public business, fall under the head of political practice in representative governments.

POLITZ, Charles Henry Louis, a distinguished German writer, professor of politics in the university of Leipsic, was born at Ernsthal, in 1772, and educated at Chemnitz. In 1791, he studied at Leipsic, in 1794, obtained the right of lecturing there, and, in 1803, was appointed extraordinary professor of philosophy. His numerous works on education, criticism, history, politics, and the German language, are much esteemed in Germany. Among them are his Weltgeschichte (Universal History, 5th ed., 1825, 4 vols.); Kleine Weltgeschichte (5th ed., 1825); Die Staatensysteme Europas und Amerikas seit 1783 (1827); Die Staatswissenschaften im Lichte unserer Zeit (5 vols., 1824; 2d ed. 1827 seq.; also, as an academical text-book, in 1825); Das Gesammtgebiet der deutschen Sprache (4 vols., 1825), with histories of several German states, &c. His Manuals of German Prose and of German Poetry also deserve notice. Since 1828, Pölitz has edited the Jahrbücher der Geschichte und Staatskunst. POLL-TAX. (See Tax.) POLLUX. (See Castor.)

POLLUX, Julius, was born in Egypt, in the latter part of the second century. He devoted himself early to letters, and settled at Athens, where he read lectures on ethics and eloquence. He became preceptor to the emperor Commodus, for whose use he drew up the catalogue of Greek synonymes in ten books, under the name

of Onomasticon, the best edition of which is that of Amsterdam (1706, folio), by Wetstein. He died A. D. 238.

POLNITZ, Charles Louis, baron von, born in 1692, early displayed marks of talent, and travelled through Europe. Of his travels he gave an amusing account in his Lettres et Mémoires (ostensibly at Amsterdam, 1727). He was also the author of L'Etat de Saxe sous Auguste III (1734), and of the well-known Saxe Galante; the Histoire de la Duchesse d'Hanovre (wife of George I) is attributed to him. After his death (1775), appeared his Mémoires sur les Quatre derniers Souverains de la Maison de Brandenbourg (1791).

POLO, Giles (commonly called Gil Polo); a Spanish poet, born at Valencia in 1517. His inclination for poetry led him to abandon the profession of law, and his first works placed him among the best Spanish poets of his time. His reputation was established by his Diana Enamorata, a pastoral romance, partly in prose and partly in verse, intended as a continuation of the Diana of Montemayor. (q. v.) In invention, Gil Polo is not inferior to his predecessor, whom he surpasses in purity of style, and in the harmony and brilliancy of his verse. He died in 1572. Cervantes excepts the Diana of Gil Polo from his list of works condemned to be burnt.

POLO, Marco, a celebrated traveller of the thirteenth century, was the son of Nicolas Polo, a Venetian merchant, who, accompanied by his brother Matthew, had penetrated to the court of Kublai, the great khan of the Tartars. This prince, being highly entertained with their account of Europe, made them his ambassadors to the pope; on which they travelled back to Rome, and, with two missionaries, once more visited Tartary, accompanied by the young Marco, who became a great favorite with the khan. Having acquired the different dialects of Tartary, he was employed on various embassies; and, after a residence of seventeen years, all the three Venetians returned to their own country in 1295, with immense wealth. Marco afterwards served his country at sea against the Genoese, and, being taken prisoner, remained many years in confinement, the tedium of which he beguiled by composing the history of the travels of his father and himself, under the title of Delle Maraviglie del Mondo da lui vedule, &c., the first edition of which appeared at Venice in 1496 (8vo.). It has been translated into various languages, the best versions of which are one in Latin (Cologne, 1671), and another in French,
