The fact itself, outset, viz. Whether perception does neces we really conceive not to be liable to any kind | sarily imply the existence of external ob of doubt or dispute; and yet the statement of jects. it, obvious as it is, seems calculated to retrench a good deal from each of the opposite assertions. The fact, if we be not greatly mistaken, is confessedly as follows.

We have occasionally certain sensations which we call heat, pain, resistance, &c. These feelings, of course, belong only to the mind, of which they are peculiar affections; and both parties are agreed in asserting, that they have no resemblance, or necessary reference, to any thing external. Dr. Reid has made this indeed the very ground-work of his reasonings on the subject of perception; and it will not probably be called in question by his antagonists, who go the length of inferring from it, that nothing but mind can be conceived to have an existence in nature. This, then, is one fact which we may safely assume as quite certain and indisputable, viz. that our sensations are affections of the mind, and have no necessary reference to any other existence. But there is another fact at least as obvious and indisputable, which the one party seems disposed to overlook, and the other to invest with undue authority, in the discussion. This second fact is, that some of the sensations in question are uniformly and irresistibly accompanied by the apprehension and belief of certain external existences, distinguished by peculiar qualities. The fact certainly admits of no dispute; and, accordingly, the philosophers who first attempted to prove that this belief was without foundation, have uniformly claimed the merit of disabusing mankind of a natural and universal illusion. Now this apprehension and belief of external existences, is in itself as much an affection of mind, as the sensations by which it is accompanied; and those who deny the distinction between perception and sensation, might be justified perhaps in asserting, that it is only a sensation of another kind: at the same time, as the essence of it consists in the apprehension of an independent existence, there can be no harm in distinguishing it, by a separate appellation, from those sensations which centre in the sentient being, and suggest to him no idea of any other existence. It is in this sense alone, it appears to us, that perception can be understood in strict philosophical language. It means no more than that affection of the mind which consists in an apprehension and belief in the existence of external objects.

Now in this sense of the word, there can be no doubt that there is a real distinction between mere sensation and perception; in

Upon this subject, we entertain an opinica which will not give satisfaction, we are afraid, to either of the contending parties. We think that the existence of external objects is not necessarily implied in the phenomena of per ception; but we think that there is no con plete proof of their nonexistence; and tha: philosophy, instead of being benefited, wou'd be subjected to needless embarrassments, by the absolute assumption of the ideal theory.

The reality of external existences is t necessarily implied in the phenomena of per ception; because we can easily imagine that our impressions and conceptions might have been exactly as they are, although matter had never been created. Belief, we familarly know, to be no infallible criterion of actu existence; and it is impossible to doubt, the we might have been so framed as to receive all the impressions which we now ascribe to the agency of external objects, from the m chanism of our own minds, or the particular volition of the Deity. The phenomena of dreaming, and of some species of madness seem to form experimental proofs of the p sibility we have now stated; and demonstrate. in our apprehension, that perception, as w have defined it, (i. e. an apprehension and be lief of external existences,) does not neces rily imply the independent reality of its ob jects. Nor is it less absurd to say that have the same evidence for the existence external objects that we have for the ex ence of our own sensations: For it is qu plain, that our belief in the former is foured altogether on our consciousness of the latter. and that the evidence of this belief is cooS) quently of a secondary nature. We ca doubt of the existence of our sensations without being guilty of the grossest cont diction; but we may doubt of the existera of the material world, without any contrad> tion at all. If we annihilate our sensatina we annihilate ourselves; and, of course, leve no being to doubt or to reason. If we ar hilate the external world, we still leave ent all those sensations and perceptions which different hypothesis would refer to its myst rious agency on our minds.

On the other hand, it is certainly going far to assert, that the nonexistence of na is proved by such evidence as necessary command our assent: Since it evidently plies no contradiction to suppose, that sh thing as matter may exist, and that an or otent being might make us capable of da

covering its qualities. The instinctive and insurmountable belief that we have of its existence, certainly is not to be surrendered, merely because it is possible to suppose it erroneous; or difficult to comprehend how a material and immaterial substance can act upon each other. The evidence of this universal and irresistible belief, in short, is not to be altogether disregarded; and, unless it can be shown that it leads to actual contradictions and absurdities, the utmost length that philosophy can warrantably go, is to conclude that it may be delusive; but that it may also be true.

This is the legitimate and inevitable ter mination of that determined scepticism which refuses to believe any thing without the highest of all evidence, and chooses to conclude positively that every thing is not, which may possibly be conceived not to be. The process of reasoning which it implies, is neither long nor intricate; and its conclusion would be undeniably just, if every thing was necessarily true which could be asserted without a con. tradiction. It is perfectly true, that we are absolutely sure of nothing but what we feel at the present moment; and that it is possible to distinguish between the evidence we have The rigorous maxim, of giving no faith to for the existence of the present impression, any thing short of direct and immediate con- and the evidence of any other existence. The sciousness, seems more calculated, we think, first alone is complete and unquestionable; to perplex than to simplify our philosophy, we may hesitate about all the rest without and will run us up, in two vast strides, to the any absolute contradiction. But the distincvery brink of absolute annihilation. We deny tion, we apprehend, is in itself of as little use the existence of the material world, because in philosophy, as in ordinary life; and the abwe have not for it the primary evidence of solute and positive denial of all existence, consciousness; and because the clear concep- except that of our immediate sensation, altoon and indestructible belief we have of it, gether rash and unwarranted.

This conclusion annihilates tainly may exist, although we cannot demonit once all external objects; and, among strate that they must; and when in spite of hem, our own bodies, and the bodies and all our abstractions, we find that we must minds of all other men; for it is quite evident come back, and not only reason with our felhat we can have no evidence of the exist- low creatures as separate existences, but enmce of other minds, except through the me-gage daily in speculations about the qualities lation of the matter they are supposed to mimate; and if matter be nothing more than in affection of our own minds, there is an end o the existence of every other. This first step, herefore, reduces the whole universe to the and of the individual reasoner; and leaves o existence in nature, but one mind, with its ompliment of sensations and ideas. The econd step goes still farther; and no one can tesitate to take it, who has ventured delibertely on the first. If our senses may deceive 18, so may our memory:-if we will not beieve in the existence of matter, because it is ot vonched by internal consciousness, and ecause it is conceivable that it should not rtist, we cannot consistently believe in the eality of any past impression: for which, in ike manner, we cannot have the direct evilence of consciousness, and of which our present recollection may possibly be fallaions. Even upon the vulgar hypothesis, we now that memory is much more deceitful han perception; and there is still greater azard in assuming the reality of any past xistence from our present recollection of it, han in relying on the reality of a present xistence from our immediate perception.

ression.

and properties of matter, it must appear, at least, an unprofitable refinement which would lead us to dwell much on the possibility of their nonexistence. There is no sceptic, probably, who would be bold enough to maintain, that this single doctrine of the nonexistence of any thing but our present impressions, would constitute a just or useful system of logic and moral philosophy; and if, after flourishing with it as an unfruitful paradox in the outset, we are obliged to recur to the ordinary course of observation and conjecture as to the nature of our faculties, it may be doubted whether any real benefit has been derived from its promulgation, or whether the hypothesis can be received into any sober system of philosophy. To deny the existence of matter and of mind, indeed, is not to philosophise, but to destroy the materials of philosophy. It requires no extraordinary ingenuity or power of reasoning to perceive the grounds upon which their existence may be doubted; but we acknowledge that we cannot see how it can be said to have been disproved; and think we perceive very clearly, that philosophy will neither be simplified nor abridged by refusing to take it for granted.

Upon the whole, then, we are inclined to think, that the conception and belief which we have of material objects (which is what we mean by the perception of them) does not amount to a complete proof of their existence, but renders it sufficiently probable: that the superior and complete assurance we have of the existence of our present sensations, does by no means entitle us positively to deny the reality of every other existence; and that as this speculative scepticism neither renders us independent of the ordinary modes of investi

than the fallacy of this reasoning. The l king, or disliking, of men to a particular object, has nothing to do with the perception of its external qualities; and they may differ entirely as to their opinion of its agreeableness, though they concur perfectly as to the description of all its properties. One man may admire a tall woman, and another a short one; but it would be rather rash to infer, that they did not agree in recognising a difference in stature, or that they had no uniform ideas of magnitude in general. In the same way, one

The little sketch we have now ventured to offer of the abstract, or thorough-going philosophy of scepticism, will render it unnecessary for us to follow our author minutely through the different branches of this inquiry. Overlooking, or at least undervaluing the indisputable fact, that our sensations are uniformly accompanied with a distinct apprehen-person may have an antipathy to salt, and sion, and firm belief in the existence of real external objects, he endeavours to prove, that the qualities which we ascribe to them are in reality nothing more than names for our peculiar sensations; and maintains accordingly, that because men differ in their opinions of the same object, it is impossible to suppose that they actually perceive any real object at all; as a real existence must always appear the same to those who actually perceive it.

another a liking for it; but they both perceive it to be salt, and both agree in describing it by that appellation. To give any degree of plausibility to Mr. Drummond's inferences, it would be necessary for him to show that some men thought brandy and Cayenne pepper in sipid and tasteless, and objected at the same time to milk and spring water as excessively acrid and pungent.

In the concluding part of his book, Mr. His illustrations are of this nature. Water, Drummond undertakes nothing less than a which feels tepid to a Laplander, would appear defence of the theory of Ideas, against the cold to a native of Sumatra: But the same arguments of Dr. Reid. This is a bold atwater cannot be both hot and cold: therefore tempt; but, we are inclined to think, not a it is to be inferred that neither of them is successful one. Mr. Drummond begins with affected by any real quality in the external the old axiom, that nothing can act but where body, but that each describes merely his it is; and infers, that as real material objects own sensations.

It existences, is the only one in behalf of which seems equally impossible to dispute, however, he can claim the support of the ancient philosophers; and it is to it he seems to allude, in several of the remarks which he makes on the illusions of sight. On the other supposition, however, he has no occasion to dispute with Dr. Reid about the existence of ideas; for the Doctor assuredly did not deny that we had sensations and perceptions, notions, recollections, and all the other affections of mind to which the word idea may be applied, in that other sense of it. There can be no question upon that supposition, but about the origin of these ideas-which belongs to another chapter.

that we should receive from this impression the belief and conception of an external existence, and that we should have the very same evidence for its reality, as for that of the objects of our other senses. But if the external existence of light be admitted, a very slight attention to its laws and properties, will show its appearances must vary, according to our distance from the solid objects which emit it. We perceive the form of bodies by sight, in short, very nearly as a blind man perceives them, by tracing their extremities with his stick: It is only the light in one case, and the stick in the other, that is properly felt or perMr. Drummond seems to lay the whole ceived; but the real form of the object is stress of his argument upon a position of indicated, in both cases, by the state and disHume's, which he applies himself to vindicate position of the medium which connects it with from the objections which Dr. Reid has urged our sensations. It is by intimations formerly against it. "The table which I see," says received from the sense of Touch, no doubt, Dr. Hume, "diminishes as I remove from it; that we ultimately discover that the rays of but the real table suffers no alteration:-it light which strike our eyes with the imprescould be nothing but its image, therefore, sions of form and colour, proceed from distant which was present to my mind." Now this objects, which are solid and extended in three statement, we think, admits pretty explicitly, dimensions; and it is only by recollecting that there is a real table, the image of which what we have learned from this sense, that is presented to the mind: but, at all events, we are enabled to conceive them as endued we conceive that the phenomenon may be with these qualities. By the eye itself we easily reconciled with the supposition of its do not perceive these qualities: nor, in strictreal existence. Dr. Reid's error, if there be ness of speech, do we perceive, by this sense, one, seems to consist in his having asserted any qualities whatever of the reflecting obpositively, and without any qualification, that ject; we perceive merely the light which it it is the real table which we perceive, when reflects; distinguished by its colour from the our eyes are turned towards it.

These variations ranged and diversified; and that, when we are clearly explained by the known properties look towards a table, we do not actually see of light, as ascertained by experiment; and the table itself, but only the rays of light evidently afford no ground for supposing any which are reflected from it to the eye.

An account of the Life and Writings of James Beattie, LL. D. late Professor of Moral Philosophy and Logic in the Marischal College and University of Aberdeen including many of his original Letters. By Sir W. FORBES of Pitsligo, Baronet, one of the Executors of Dr. Beattie. 2 vols. 4to. pp. 840. Edinburgh and London: 1806.

DR. BEATTIE'S great work, and that which was undoubtedly the first foundation of his celebrity, is the "Essay on the Nature and Immutability of Truth;" on which such unThe greater part of this article also is withheld from the present reprint, for the reasons formerly stated; and only those parts given which bear upon points of metaphysics.

measured praises are bestowed, both by his present biographer, and by all the author's male and female correspondents, that it is with difficulty we can believe that they are speaking of the performance which we have just been wearying ourselves with looking over. That the author's intentions were good, and his convictions sincere, we entertain not

the least doubt; but that the merits of his book have been prodigiously overrated, we think, is equally undeniable. It contains absolutely nothing, in the nature of argument, that had not been previously stated by Dr. Reid in his "Inquiry into the Human Mind;" and, in our opinion, in a much clearer and more unexceptionable form. As to the merits of that philosophy, we have already taken occasion, in more places than one, to submit our opinion to the judgment of our readers; and, after having settled our accounts with Mr. Stewart and Dr. Reid, we really do not think it worth while to enter the lists again with Dr. Beattie. Whatever may be the excellence of the common-sense school of philosophy, he certainly has no claim to the honours of a founder. He invented none of it; and it is very doubtful with us, whether he ever rightly understood the principles upon which it depends. It is unquestionable, at least, that he has exposed it to considerable disadvantage, and embarrassed its more enlightened supporters, by the misplaced confidence with which he has urged some propositions, and the fallacious and fantastic illustrations by which he has aimed at recommending many others.

His confidence and his inaccuracy, however, might have been easily forgiven. Every one has not the capacity of writing philosophically: But every one may at least be temperate and candid; and Dr. Beattie's book is still more remarkable for being abusive and acrimonious, than for its defects in argument or originality. There are no subjects, however, in the wide field of human speculation, upon which such vehemence appears more groundless and unaccountable, than the greater part of those which have served Dr. Beattie for topics of declamation or invective.

His first great battle is about the real existence of external objects. The sceptics say, that perception is merely an act or affection of the mind, and consequently might exist without any external cause. It is a sensation or affection of the mind, to be sure, which consists in the apprehension and belief of such external existences: But being in itself a phenomenon purely mental, it is a mere supposition or conjecture to hold that there are any such existences, by whose operation it is produced. It is impossible, therefore, to bring any evidence for the existence of material objects; and the belief which is admitted to be inseparable from the act of perception, can never be received as such evidence. The whole question is about the grounds of this belief, and not about its existence; and the phenomena of dreaming and madness prove experimentally, that perception, as characterised by belief, may exist where there is no external object. Dr. Beattie answers, after Dr. Reid, that the mere existence of this instinctive and indestructible belief in the reality of external objects, is a complete and sufficient proof of their reality; that nature meant us to be satisfied with it; and that we cannot call it in question, without running into the greatest absurdity.

This is the whole dispute; and a pretty correct summary of the argument upon both sides of the question. But is there any thing here that could justify the calling of rames, or the violation of decorum among the disputants? The question is, of all other questions that can be suggested, the most purely and entirely speculative, and obviously disconnected from any practical or moral consequences. After what Berkeley has written on the subject, it must be a gross and wilful fallacy to pretend that the conduct of men can be in the smallest degree affected by the opinions they entertain about the existence or nonexistence of matter. The system which maintains the latter, leaves all our sensations and perceptions unimpaired and entire; and as it is by these, and by these only, that our conduct can ever be guided, it is evident that it can never be altered by the adoption of that system. The whole dispute is about the cause or origin of our perceptions; which the one party ascribes to the action of external bodies, and the other to the inward development of some mental energy. It is a question of pure curiosity; it never can be decided; and as its decision is perfectly indifferent and immaterial to any practical pur pose, so, it might have been expected that the discussion should be conducted without virulence or abuse.

The next grand dispute is about the evidence of Memory. The sceptics will have it, that we are sure of nothing but our present sensations; and that, though these are sometimes characterised by an impression and belief that other sensations did formerly exist, we can have no evidence of the justice of this belief, nor any certainty that this illusive conception of former sensation, which we call memory, may not be an original affection of our minds. The orthodox philosophers, on the other hand, maintain, that the instinctive reliance we have on memory is complete and satisfactory proof of its accuracy; that it is absurd to ask for the grounds of this belief; and that we cannot call it in question without manifest inconsistency. The same observations which were made on the argument for the existence of matter, apply also to this controversy. It is purely speculative, and with out application to any practical conclusion. The sceptics do not deny that they remember like other people, and, consequently, that they have an indestructible belief in past events or existences. All the question is about the origin, or the justice of this belief;-whether it arise from such events having actually happened before, or from some original affection of the mind, which is attended with that impression.

The argument, as commonly stated by the sceptics, leads only to a negative or sceptical conclusion. It amounts only to this, that the present sensation, which we call memory, affords no conclusive evidence of past existence and that for any thing that can be proved to the contrary, nothing of what we remember may have existed. We think this undeniably true; and so we believe did Dr. Beattie. He thought it also very useless; and there, too,
