nately not alive; that it was obvious to himself that he existed for and during the time that he thought, itched, or ate, but that he had no proof of existence as soon as these were over.

But I have said, that M. Des Cartes's philosophy consists not only in demanding proofs where no proofs are necessary, and where the truisms are so clear as to render it ludicrous to ask for them, but in taking for granted propositions that evidently demand proof. And I now allude to his whole doctrine of innate ideas-of axioms or principles planted in the mind by the hand of nature herself, and which are evidently intended to supply the place of the intelligible world of Plato and Aristotle.

of these I have only produced a small sample, and it is not necessary to bring more to market. Let us state his innate idea of a God. It is, I admit, a very reverential, correct, and perfect one, and does him credit as a theologist: but I am not at present debating with him as a theologist, but as a logician. It is in truth owing to its very perfection that I object to it; for there is strong ground to suspect, notwithstanding all his care to the contrary, that he has obtained it from induction, rather than from impulse; from an open creed, than from a latent principle. If such an idea be innate to him, there can be no question that it must be also innate to every one else. Now, it so happens that the ideas of other men, in different parts of the world, wander from his own idea as far as the north pole from the south. There are some barbarians, we are told, so benighted as to have no idea of a God at all. Such, as Mr. Marsden, his Majesty's principal chaplain in New South Wales, informs us, are the very barbarous aboriginal tribes of that vast settlement. “ They have no knowledge," says he,“ of any religion, false or true.” There are others, whose idea of a God has only been formed in the midst of gloom and terror: and who hence, with miserable ignorance, represent him, in their wooden idols, under the ugliest and most hideous character their gross imagination can suggest. Atheism, in the strictest sense of the term, is at this moment, and has been for nearly a thousand years at least, the established belief of the majority, or rather of the whole Burman empire; the fundamental doctrine of whose priesthood consists in a denial that there is any such power as an eternal independent essence in the universe ; and that at this moment there is any God whatever; Guadama, their last Boodh, or deity, having, by his meritorious deeds, long since reached the supreme good of Nigbar, or annihilation ; which is the only ultimate reward in reserve for the virtuous among mankind ;* while the ideas of the wisest philosophers of Greece appear to have fallen far short of the bright exemplar of M. Des Cartes.

That Des Cartes himself was possessed of this idea at the time he wrote, no man can have any doubt; but what proof have we that he possessed it INNATELY, and that he found it among the ORIGINAL FURNITURE OF HIS MIND?

In like manner, he tells us, that his knowledge of MATTER is derived from the same unerring source; that its idea exists within him, and that this idea

* The most authentic account of the tenets of Boodhism which have of late years been communicated to the world, are those furnished by Mr. Judson, an American missionary, who for the last ten or twelve years has been stationary at Rangoon or Ava, bas acquired an accurate knowledge of the Burman and Pali, or vulgar and sacred tongue, and has translated the whole of the New Testament into the former. His very interesting account of the mission of himself and his colleagues, as well as of the national creed of this extraordinary people, is to be found in his correspondence with the American Baptist Missionary Board, as also in " An Account of the American Baptist Mission to the Burman Empire, in a series of Letters addressed to a Gentleman in London, by A. H. Judson, 8vo. Lond. 1823." The whole universe, according to the principles of Boodhism, is governed by fate, which has no more essential existence than chance. A Boodh, or god, is occasionally produced, and appears on earth, the last of whoin was Guadama. But gods and men must equally follow the law or order of fate; they must die, and they must suffer in a future state according to the sins they have committed on earth; and, when this penance has been completed, they reach alike the supreme good of Nigbar, or ulter annihilation. Guadama, their last deity, many hundred years ago reached this state of final beatitude, and another deity is soon expected to make his appearance. An eternal sell existent being is, in the opinion of the Boodhists, an utter iinpoesi i bility, and they hear of such a doctrine with horror. When Mr. Judson had obtained an audience of the Burman emperor in his palace at Ava, to solicit protection and toleration, his petition was first read, and then a little tract, containing the chief doctrines of Christianity, printed in the Burman tongue, put into The emperor's hands. "He held the tract," says Mr. Judson, "long enough to read the first two sentences. which assert that there is one eternal God, who is independent of the incidents of mortality, and that, beside him, there is no god; and then, with an air of indifference, perhaps of disdain, he dashed it down to the ground.-Our rate was decided."-Ib, p. 231.

represents it to be an extended substance, without any other quality, and embracing space as a part of itself. Now, if such an idea appertained naturally to him, it must, in like manner, appertain naturally to every one. Let me, then, ask the audience I have the honour of addressing, whether the same notion has ever presented itself, as it necessarily ought to have done, to the minds of every one or of any one before me ? and whether they seriously believe that SPACE is a part of MATTER ? So far from it, that I much question whether even the meaning of the position is universally understood; while, with respect to those by whom it is understood, I have a shrewd suspicion it is not assented to; and that they would even apprehend some trick had been played upon them if they should find it in their minds. The good father Malebranche, as excellent a Cartesian as ever lived, and who possessed withal quite mysticism enough to have succeeded Plato, upon his death, and turned Xenocrates out of the chair, suspected that tricks like these are perpetually played upon us. For he openly tells us, in his Recherche de la Vérité, that ever since the fall, Satan has been making such sad work with our senses, both external and internal, that we can only rectify ourselves by a vigorous determination to doubt of every thing, after the tried and approved Cartesian recipe: and if a man, says he, has only learned to doubt, let him not imagine that he has made an inconsiderable progress. And for this purpose, he recommends retirement from the world, a solitary cell, and a long course of penitence and water-gruel : after which our innate ideas, he tells us, will rise up before us at a glance: our senses, which were at first as honest faculties as one could desire to be acquainted with, till debauched in their adventure with original sin, will no longer be able to cheat us, we shall see into the whole process of transubstantiation, and though we behold nothing in matter, we shall behold all things in God.

It may, perhaps, be conceived that I treat the subject before us somewhat too flippantly or too cavalierly. It is not, however, the subject before us that I thus treat, but the hypothesis; and, in truth, it is the only mode in which I feel myself able to treat it at all; for I could as soon be serious over the “Loves of ihe Plants," or "The Battle of the Frogs." And I must here venture to extend the remark a little farther and to add, that there is but one hypothesis amid all those that yet remain to be examined, that I shall be able to treat in any other manner; for, excepting in this one, there is not a whit of superiority that I can discover in any of them; and the one I refer to, though I admit its imperfections in various points, is that of our own enlightened countryman, Mr. Locke. I may, perhaps, be laughed at in my turn, and certainly should be so if I were as far over the Tweed as over the Thames, and be told that I am at least half a century behind the times. Yet, by your permission, I shall dare the laugh, and endeavour, at least, to put merriment against merriment; and shall leave it to yourselves to determine, after a full and impartial herring, who has the best claim to be pleasant. So that the study of metaphysics may not, perhaps, appear quite so gloomy and repugnant as the writings of some philosophers would represent it. If it have its gravity, it may also be found to have its gayety as well; and to prove that there is no science in which it better becomes us to adopt the maxim of the poet, and to

Laugh where we may, be serious where we can,
But vindicate the ways of God to inan.

LECTURE IV.

ON HUMAN UNDERSTANDING.

(The Subject continued.) In our preceding study we commenced a general survey of the chief opi. nions and hypotheses that have been urged in different periods upon the important subject of Human Understanding; and, opening our career with the Greek schools, we closed it with that of Des Cartes.

Des Cartes, who was born in 1596, was for nearly a century the Aristotle of his age; and, although from his very outset he was opposed by his contemporaries and literary friends Gassendi and Hobbes, he obtained a complete triumph, and steadily supported his ascendant, till the physical philosophy of Newton, and the metaphysical of Locke, threw an eclipse over his glory, from which he has now no chance of ever recovering.

Nothing, however, can prove more effectually the influence which fashion operates upon philosophy as well as upon dress, than a glance at the very opposite characters by whom the Cartesian system was at one and the same time principally professed and defended— Malebranche and Spinosa, Leibnitz and Bayle. It would, perhaps, be impossible, were we to range through the whole scope of philosophical or even of literary biography, to collect a more motley and heterogeneous group: the four elements of hot, cold, moist, and dry cannot possibly present a stronger contrast; a mystical Catholic, a Jewish materialist, a speculative but steady Lutheran, and a universal skeptic.

It was only, however, for want of a simpler and more rational system, that Des Cartes continued so long and so extensively to govern the metaphysical taste of the day. That system was at length given to the world by Mr. Locke, and the “PRINCIPIA PHILOSOPHIÆ” fell prostrate before the “Essay CONCERNING HUMAN UNDERSTANDING."

This imperishable work made its first appearance in 1689: it may, perhaps, be somewhat too long; it may occasionally embrace subjects which are not necessarily connected with it: its terms may not always be precise, nor its opinions in every instance correct; but it discovers intrinsic and most convincing evidence that the man who wrote it must have had a head peculiarly clear, and a heart peculiarly sound. It is strictly original in its matter, highly important in its subject, luminous and forcible in its argument, perspicuous in its style, and comprehensive in its scope. It steers equally clear of all former systems: we have nothing of the mystical archetypes of Plato, the incorporeal phantoms of Aristotle, or the material species of Epicurus; we are equally without the intelligible world of the Greek schools, and the innate ideas of Des Cartes. Passing by all which, from actual experience and observation it delineates the features and describes the operations of the human mind, with a degree of precision and minuteness which have never been exhibited either before or singe. “Nothing,” says Dr. Beattie, and I readily avail myself of the acknowledgment of an honest and enlightened antagonist, “ was farther from the intention of Locke than to encourage verbal controversy, or advance doctrines favourable to skepticism. To do good to mankind by enforcing virtue, illustrating truth, and vindicating liberty, was his sincere purpose. His writings are to be reckoned among the few books that have been productive of real utility to mankind.”+

To take this work as a text-book, of which, however, it is well worthy, would require a long life instead of a short lecture: and I shall, hence, beg leave to submit to you only a very brief summary of the more important part of its system and of the more prominent opinions it inculcates, especially in

respect to the powers and process of the mind in acquiring knowledge. The work consists of four divisions, the first of which, however, is merely intro. ductory, and intended to clear the ground of that multitude of strong and deep-rooted weeds at which we have already glanced, and which, under the scholastic name of præcognita, innate ideas, maxims, and dictates, or innate speculative and practical principles, prevented the growth of a better har. vest; and, to a certain extent, superseded the necessity of reason, education, and revelation, of national institutions and Bible societies; by teaching that a true and correct notion of God, of self or consciousness, of virtue and vice, and, consequently, of religious and moral duties, is imprinted by nature on the mind of every man; and that we cannot transgress the law thus originally implanted within us without exposing ourselves to the lash of our own consciences. Discarding for ever all this jargon of the schools, the Essay before us proceeds in its three remaining parts to treat of ideas, which, in the popular, and not the scholastic, sense of the term, are the elements of knowledge; of WORDS, which are the signs of ideas, and consequently the circulating medium of krowledge; and of KNOWLEDGE itself, which is the subject proposed, and the great end to be acquired.

The whole of the preceding rubbish, then, being in this manner cleared away, the elaborate author proceeds to represent to us the body and mind as equally at birth a tabula rasa, or unwritten sheet of paper: as consisting equally of a blank or vacuity of impressions, but as equally capable of acquiring impressions by the operation of external objects, and equally and most skilfully endowed with distinct powers or faculties for this purpose ; those of the body being the external senses of sight, hearing, smell, taste, and touch; and those of the mind the internal senses of perception, reason, judgment, imagination, and memory.*

It is possible that a few slight impressions may be produced a short time antecedently to birth; and it is certain that various instinctive tendencies, which, however, have no connexion with the mind, are more perfect, because more needful, at the period of birth than ever afterward; and we have also frequent proofs of an hereditary or accidental predisposition towards particular subjects. But the fundamental doctrine before us is by no means affected by such collateral circumstances; to the correctness of which our most eminent logicians of later times have given their entire suffrage. Thus Bishop Butler, and it is not necessary to go farther than this eminent casuist: -"In these respects," meaning those before us, “mankind is left by nature an unformed, unfinished creature, utterly deficient and unqualified, before the acquirement of knowledge, experience, and habits, for that mature state of life which was the end of his creation, causidering him as related only to this world. The faculty of reason is the candle of the Lord within us; though it can afford no light where it does not shine, nor judge where it has no principles to judge upon.”+

External objects first impress or operate upon the outward senses, and these senses, by means hitherto unexplained, and, perhaps, altogether inexplicable, immediately impress or operate upon the mind, or excite in it perceptions or ideas of the presence and qualities of such objects; the word idea being employed in the system before us, not, as we have already hinted at, in any of the significations of the schools, but in its broad and popular meaning, as importing " whatever a man observes and is conscious to himself he has in his mind;"I whatever was formerly intended by the terms archetype, phantasm, species, thought, notion, conception, or whatever else it may be, which we can be employed about in thinking. And to these effects, without puzzling himself with the inquiry how external objects operate upon the senses, or the senses upon the mind, Mr. Locke gave the name of ideas of SENSATION, in allusion to the source from which they are derived.

But the mind, as we have already observed, has various powers or faculties as well as the body; and they are quite as active and lively in their respective functions. In consequence of which the ideas of external objects are not only perceived, but retained, thought of, compared, compounded, abstracted, doubted, believed, desired; and hence another fountain, and of a very capacious flow, from which we also derive ideas, namely, a reflex act or perception of the mind's own operations; whence the ideas derived from this foun. tain are denominated ideas of REFLECTION.

The ideas, then, derived from these two sources, and which have sometimes been called OBJECTIVE, and SUBJECTIVE,* constitute all our experience, and consequently all our knowledge. Whatever stock of information a man may be possessed of, however richly he may be stored with taste, learning, or science, if he turn his attention inwards, and diligently examine his own thoughts, he will find that he has not a single idea in his mind but what has been derived from the one or the other of these two channels. But let not this important observation be forgotten by any one; that the ideas the mind possesses will be fewer or more numerous, simpler or inore diversified, clear or confused, according to the number of the objects or subjects presented to it, and the extent of its reflection and examination. Thus, a clock or a landscape may be for ever before our eyes, but unless we direct our attention to them, and study their different parts, although we cannot be deceived in their being a clock or a landscape, we can have but a very confused idea of their character and composition. The ideas presented to the mind, from which of these two sources soever derived, or, in other words, whether objective or subjective, are of two kinds, simple and COMPLEX.

SIMPLE IDEAS consist of such as are limited to a single notion or perception; as those of unity, darkness, light, sound, hardness, sweetness, simple pain, or uneasiness. And in the reception of these the mind is passive, for it can neither make them to itself, nor can it, in any instance, have any idea which does not wholly consist of them; or, in other words, it cannot contemplate any one of them otherwise than in its totality. Thus, on looking at this single sheet of paper, I have the idea of unity; and though I may divide the single sheet of paper into twenty parts, I cannot divide the idea of unity into twenty parts; for the idea of unity will and must as wholly accompany every part as it accompanies the collective sheet. And the same remark will apply to all the rest.

COMPLEX ideas are formed out of various simple ideas associated together, or contemplated derivatively. And to this class belong the ideas of an army, a batlle, a triangle, gratitude, veneration, gold, silver, an apple, an orange: in the forination of all which it must be obvious that the mind is active, for it is the activity of the mind alone that produces the complexity out of such ideas as are simple. And that the ideas I have now referred to are complex, must be plain to every one; for every one must be sensible that the mind cannot form to itself the idea of an orange without uniting into one aggregate the simple ideas of roundness, yellowness, juiciness, and sweetness. In like manner, in contemplating the idea of gold, there must necessarily be present to the mind, and in a complex or aggregate form, the ideas of great weight, solidity, yellowness, lustre: and if the idea be very accurate, great malleability and fusibility.

Complex ideas are formed out of simple ideas by many operations of the mind; the principal of which, however, are some combination of them, some abstraction, or some comparison. Let us take a view of each of these :

u On appelle, dans la philosophie Allemande, idées subiectives celles que naissent de la nature de notre ntelligence et de ses facultes, et idees objectives toutes cellee que sont excitées par les sensations."--Mad. e Staël Holstein, de l'Allemagne, tom. ill. p. 76.

Mad. de Stael, however, has fallen into the cornmon error of the French philosophers, from whom she appears to have generally informed herself of the principles of Locke's system, in supposing that he derived all ideas from sensation. "A l'époque ou parui la Critique de la Raison pire, il n'existoit que deux systèmes sur l'entendernent humain parmi les penseurs : l'une, celui de Locke, attribuit toutes nos idées d ros sensations ; l'autre, celui de Des Cartes et de Leibnitz, s'attachoit a demontrer la spiritualité et l'acti vité de l'âme, de libre arbitre, enfin toute la doctrine idéaliste."-Ib. p. 70.
