The word "science," in its most comprehensive sense, means "knowledge." In its general acceptation, it is "knowledge reduced to a system;" that is to say, arranged in regular order, so that it can be conveniently taught, easily remembered, and readily applied to useful purposes. An art is the application of knowledge to some practicable end,—to answer some useful or ornamental purpose. The sciences, are sometimes divided into the abstract and the natural; by the former we are taught the knowledge of reasons and their conclusions; by the latter we are enabled to find out causes and effects, and to study the laws by which the material world is governed. To the abstract sciences belong, first, language, whether oral or written, including grammar, logic, &c.; secondly, notation, including arithmetic, algebra, geometry, &c. Philosophy inquires into the laws that regulate the phenomena of nature, whether in the material or immaterial world; it is generally divided into three classes, two of which are material and one immaterial. The material are, first, those which relate to number and quantity; secondly, those which relate to matter. The immaterial are those which relate to mind. The second class of the material is called "natural philosophy" or "physics," and sometimes the "physical sciences." Natural philosophy, in its most comprehensive sense, has for its province the laws of matter, whether organic or inorganic. These laws may regard either the motions or properties of matter, and hence arises their division into two branches—first, those which regard the motions of matter, which are called mechanics; and secondly, those which regard the properties of matter, which are subdivided, and have various names, according to the different objects of investigation. When the inquiry is confined to organized bodies and life, it is called physiology; which is again subdivided into zoology and botany. When it treats of inorganic matter, it is subdivided into chemistry, anatomy, medicine, mineralogy and geology. The principles of natural philosophy rest upon observation and experiment. Observation is the noticing of natural phenomena at they occur, without any attempt to influence the frequency of their occurrence. Experiment consists in putting in action causes and agents, over which we have control, for the purpose of noticing their effects. From a comparison of a number of facts, obtained from either observation or experiment, the existence of general laws are proved. The laws of man are complicated; to understand their objects, we are often obliged to take the most circuitous routes; but the laws by which nature governs all her works are beautifully simple, and they are found to lead directly to the end she has in view. To study them, therefore, according to the rules that have been laid down, viz: from observation and experiment, is pleasant and easy. The principal difficulties that have arisen, are owing to the improper manner in which the subjects connected with natural history have often been treated. Natural philosophy regards what was the condition of natural bodies: but many persons exert the whole force of their genius to discover what they might have been. And as there is no department of natural philosophy into which this erroneous method of procedure has made greater inroads than geology, nor any science that has suffered so severely in such conflicts, it may not be amiss to appropriate half an hour to the inquiry whence this error has arisen; and, if possible, point out the best method of avoiding its dangerous tendency. The word geology is derived from two Greek words, signifying "the earth" and "reason;" and it is that science which teaches the structure of the crust of the earth, and ascertains its mineralogical materials, and the order in which they are disposed, and their relations to each other. Geognosy is used by the French as synonymous to geology, but in English is generally understood to be synonymous to cosmogony; which is an inquiry, or rather a speculation, as to the original formation or creation of the world; hence geognosy has sometimes been called "speculative geology." In pursuing the examinations to which geology leads, we reason from facts, as is done in other branches of natural science. The strata of the crust of the earth, owing to the disturbed manner in which we now find them, are in a great measure open to our examination; their composition, formation, deposition, eruption, depression, succession, and mineralogical contents, are all objects of sensation. The objects of geognosy (in the English sense of the word) are, on the other hand, for the most part, ideal, visionary and delusive. We are sensible that this earth exists and that it is material, and therefore we know that it must have been created. We know that it was not created by man, who hath not the power to add to it one single atom, nor diminish it by a single grain—so that it is manifest that it was created by a superior and omnipotent power; but by what process it was done is a mystery, and the more we seek to discover it the more we expose our ignorance. The geologist, like the mathematician, deals with the understanding; his advance is wary, admitting no conclusion until his premises are fully established. The professor of geognosy, on the contrary, addresses himself entirely to the imagination, and he delights in hypothesis and suppositions. The progress of the geologist is necessarily slow; he is like the patient miner, making his laborious but determined way into the solid rock: but the professor of geognosy will make a world or even a universe in an hour, for he deals in fancy and works in visionary speculations. The geologist delves into the bowels of the earth in search of useful metals, earths and combustible matters, which nature has kindly placed within his reach, and he strives to turn them to the best advantage in administering to the wants and increasing the comforts and convenience of his fellow creatures; but all the labors of the professor of geognosy are directed to discover a secret which appears to be hidden from human ken; a secret, the discovery of which would not, as far as we can judge, add any thing to the sum of human happiness. It excites our astonishment therefore, that so many persons of fine genius and brilliant talents should have wasted so much time in forming what are called theories of the earth, who might have been so much better employed in investigating the secondary causes by which the materials composing the crust of this earth obtained their present forms, and in examining the changes which those materials are daily undergoing. But so it is; the curiosity so natural to our species opens the way—the vanity of being supposed to have penetrated deeper than others into the abstruse mysteries of nature urges them forward—the silly pride of having in their own estimations discovered the hidden ways of Providence quickens their zeal; and, such is the love of the marvellous, that if they exhibit only a tolerable degree of ingenuity, and embellish their performances with a few flowers of rhetoric, they are sure to command more attention and praise from the general mass of readers, than can be extorted by the most laborious examination of nature's works. While Martin Lister was ridiculed by Doctor King for the laudable minuteness with which he described the different natural objects he met with in his journey through France, Mr. Thomas Burnet, for a fanciful theory of the earth, was extravagantly lauded by a writer in the Spectator. Saussure crossed the Alps in fourteen places; Humboldt traversed nearly one half of the habitable globe; Cuvier spent seven years in the study of comparative anatomy, as subservient to the study of fossil remains; and Hauy studied geometry for the sole purpose of obtaining a knowledge of crystalography; but neither of these distinguished philosophers have been able to win the laurels that have been heaped upon the brow of Count Buffon for a visionary hypothesis which he calls a theory of the earth.
The substitution of these hypotheses for knowledge, unfortunately, has not been confined to the early and dark ages of geology. One entirely new theory of the earth was published as lately as the year 1825—another in 1827—and a third in 1829. It is proper therefore that the student should be warned against their fascinating and baneful influence.

ESSAY ON LUXURY.
Of the various researches, which engage this enlightened age, there is not one perhaps more important, whether we consider the public weal, or the general interest of humanity, than that which concerns luxury. It is regarded by some as the source of the greatest calamities; by others as a source of opulence and industry. It has been said and repeated thousands of times, that we often dispute, because we do not understand each other, and that we give a different meaning to words we use, because we do not define them with sufficient precision. This is frequently true; but cases will often arise where, though the words of a proposition are taken in precisely the same acceptation, and those who employ them reason alike, yet the result of their reasonings are diametrically opposite. Luxury has at all times been considered as a cause of the corruption of morals, and the destruction of empires; but in the last ages, it has not wanted its advocates—nay, they have even pretended, that it was necessary to render empires flourishing, to favor commerce, industry, circulation, manufactures; and that it alone would redress the inequality of various conditions, by making the superfluities of some contribute to relieve the necessities and wants of others. The contrary has always been held as an irrefragible axiom. But still its advocates maintain, that it nourishes all the refinements of good taste, and developes the talents of the artist, whose art and genius are encouraged by the profusion and prodigality which it produces. This is indeed the favorable side of the picture; but how often is it, that what we see in an object, is not all we might see there, and that one truth by intercepting the view of others, conducts us often to error. It is possible by considering the subject more attentively, though we may find all we have said, true to a certain degree, yet on the other hand, the evil, which excessive luxury produces, is infinitely more dangerous;—and speculation will confirm what the experience of all ages has demonstrated. It is an historical and invariable truth, that excessive luxury has always been the harbinger of the destruction of a state. I may add, it has always been the fatal cause. Labor and economy are the principles of true prosperity—the eclat of pomp and magnificence without them, is only a false splendor, which conceals inward misery. But it is here, we must stop for a moment, before we further advance, in order to have a precise idea, of what we understand by the word luxury. If by it, we mean every thing which exceeds the physical necessities of life, I should apologize to the learned. But I do not mean to fix the boundary by the laws of Lycurgus. I agree farther, that what may be luxury at one time, is not so at another; but it is in this gradation, which may be extended to infinity, that we ought wisely to seize that degree of the scale, where it degenerates into vice—I mean political vice, which far from being useful becomes prejudicial to a state. This distinction is still local, individual, and subject to different times and eras. What is a ruinous luxury in one country, would perhaps be useful or indifferent in another. A destructive and indecent luxury in one order of society, is honorable, indispensable and useful in another; and in short, in a country where a certain degree of luxury is necessary, there may be times, when sumptuary laws would be useful. If we proceed to analyze its principles, we shall see that though abstractedly, luxury may appear to produce certain advantages, yet in general it is the cause of the greatest disorders. If the expense or luxury of each individual were the thermometer of his fortune, the degree of luxury would certainly be the symptom of power, riches, industry and opulence of a state, but it would not on this account, be the cause; for what must be the consequence, when vanity and self-love excited by opinion, by custom and by pride, make us aspire at an external show far beyond our condition in life, and run into extravagancies, which we cannot support? This is to sap a commodious edifice in order to build a larger, which we can never erect. The state loses the house and does not gain the palace. In a country where luxury reigns, this example may be seen every day and in every order of the state. The "Luxury" then of which I speak, is that which prompts many to run into expenses, beyond what their circumstances will admit, by the respect attached to it, and by that contempt, with which those are treated, who do not maintain a similar profusion; by the universality of the custom; and by the opinions of others, which render the superfluous, the useless, the frivolous, almost necessary and indispensable. It is on this account, that the felicity, or apparent power, which luxury appears sometimes to communicate to a nation, is comparable to those violent fevers, which lend for a moment, incredible nerve to the wretch, whom they devour, and which seem to increase the natural strength of man, only to deprive him at length of that very strength and life itself. It is likewise physically true, that excessive luxury impairs the body and destroys courage. Effeminacy enervates the one, and artificial wants blunt the other; wants multiplied become habitual, nor by diminishing the pleasures of possession, do they always diminish the despair of privation. Let us not say that the misfortunes of individuals, do not concern the public; when many suffer, the public must feel it. If it were true, that the possessions of those who are ruined, are found dispersed among other individuals, the ruin of the unfortunate would still be prejudicial to the state; because it is the number of individuals in easy circumstances, which create its wealth. But it is absolutely false, that those possessions are found in the mass of the public; if the possession of each individual consisted in silver, this might be so; but property for the most part is fictitious or artificial: industry, credit, opinion, form a great part of the riches of each individual,—which vanish, and are annihilated with the ruin of his former possessions, and are forever lost with respect to the state. Besides, lands are best cultivated, when divided among many hands. An hundred husbandmen in easy circumstances, are infinitely more useful to a state, than an hundred poor ones, or ten powerfully rich. It is the quantity of consumers, who regularly make an honest, well supported and permanent expense,—which augments industry, circulation, commerce, manufactures, and all the useful arts. But when excessive luxury causes, that the arts are lucrative in the inverse ratio of their utility, the most necessary become the most neglected, and the state is depopulated by the multiplication of subjects, who are a charge to it. It is then we fall precisely into the case of him, who cuts down the tree to get the fruit: what weakens each member of a body, must necessarily weaken the body itself; but excessive luxury weakens, without contradiction, each member of a body politic, physically and morally,—consequently it must undermine and destroy the constitution of that body. Another inconvenience attending luxury is, that according to the order of nature, the propagation of the species ought continually to increase in a country, if some inherent vice, either physical or moral, do not prevent it. We have seen in those times, when luxury prevailed only among the superior class, swarms issue from the state, without depopulating it, in order to establish themselves in other places. But the luxury of parents, whose baleful example is often the sole inheritance of their offspring, forces them necessarily into a state of celibacy; whereas it is evident, that by a division of property among their children, the latter might, with industry and care, having a principal to begin with, increase their hereditary wealth and enrich the state. Every thing conspires, where luxury reigns, to corrupt the morals. It eclipses, stifles, or rather destroys the virtues. It knows no object but the gratification of certain imaginary pleasures, more illusory than the honor, which it attracts. Mankind are born perhaps with no particular bias to fraud or injustice. It is want, either real or artificial, which creates the robber or the murderer; but for the most part, those crimes, which are most dangerous to society, take their origin from artificial wants, which ensue from "Luxury." The brother violates the strongest ties of nature—the patriot plunges the dagger into the bosom of his country. It was "Luxury," which called from Jugurtha his celebrated observation on Rome. It would be endless to attempt to enumerate the examples of ruin, and of those calamities, which have ever followed in its train. But how is this most dangerous of evils to be guarded against? Sumptuary laws would not always be efficacious. They do not always answer the end proposed. They are eluded by refinements upon "Luxury" until it becomes "Luxury" in excess. It must be the province of the legislature to prevent this abuse. The most effectual laws would be those, which would remove that ridiculous respect, which is paid to frivolous exteriors, and would attach real respect to merit alone; which would destroy that unjust contempt into which modest simplicity has fallen by a depravity of taste and reason. He, who by a wise legislation would discover the secret of banishing those prejudices, would render an essential service to humanity. Virtue and emulation would flourish—vice and folly no longer appear. After all, I would not have it forgot, that I have agreed, that what would be "Luxury" at one time, and for one order of people, is not so for another. The "Luxury" which destroys a republic, would not perhaps destroy a large kingdom; but there is a degree of "Luxury" prejudicial to the most opulent monarchy. The universal use of wine would be ruinous to this country, but not so to France. The detail and analysis of those distinctions, are perhaps the most important object to humanity. I am persuaded, that the public good, the repose of families, and the happiness of the present and future generations depend upon it.
