agreement in meaning between one form of expression and another. Into the illustration of this most important proposition, it must be seen to be impossible for us here to proceed. We cannot direct our readers to a better source of instruction than Mr. Stewart himself, in the chapter on abstraction, to which we have so repeatedly referred. "If the subjects of our reasoning," says Mr. Stewart," be general (under which description I include all our reasonings, whether more or less comprehensive, which do not relate merely to individuals,) words are the sole objects about which our thoughts are employed." It is impossible more explicitly to admit, that all general propositions, and all general reasonings are merely verbal; in other words, assert or deduce the sameness in point of meaning, in some one or more respects, between two general expressions. Even in the volume more immediately before us, he expressly says, "In the sciences of arithmetic and algebra, all our investigations amount to nothing more than to a comparison of different expressions of the same thing. Our common language, indeed, frequently supposes the case to be otherwise; as when an equation is defined to be, A proposition asserting the equality of two quantities.' It would, however, be much more correct to define it, A proposition asserting the equivalence of two expressions of the same quantity." It would imply an incapacity for consistent reasoning, of which we are far from suspecting Mr. Stewart, to suppose that he places any essential distinction between arithmetical or algebraical deductions, and other species of general reasoning at large; only because these sciences are possessed of more commodious signs than ordinary language affords. Indeed, upon turning to the chapter on abstraction, we find that Mr. Stewart himself expressly says; "The analogy of the algebraical act may be of use in illustrating these observations. The difference, in fact, between the investigations we carry on by its assistance, and other processes of reasoning, is more inconsiderable than is commonly imagined; and, if I am not mistaken, amounts only to this, that the former are expressed in an appropriate language, with which we are not accustomed to associate particular notions. Hence they exhibit the efficacy of signs as an instrument of thought, in a more distinct and palpable manner, than the speculations we carry on by words, which are continually awakening the power of concep tion." It is, indeed, not a little remarkable, that an author who denies the existence of abstract ideas, and so completely recognizes the nature of general terms, should lose sight of this doctrine so frequently as Mr. Stewart, in all his remaining inquiries. In truth we are led to suspect, that Mr. Stewart arrived at his present opinions concerning abstraction, at a period pretty late in life, when his conclusions on the other parts of his subject

were already formed, and were committed to writing; and that the strength of his original associations permitted him not to discover the changes which an alteration in so fundamental a point required in the rest of his speculations.

We may now, then, draw together the conclusions at which which we seem to have arrived. If all truths are either particular or general, the powers by which we recognize and discover truth about which Mr. Stewart writes with such an air of mystery, and which, after many pages of high sounding disquisition, he leaves unexplained-are tolerably obvious and familiar. With regard to all individual, that is, all real existences, the faculties by which we discover what in this case we mean by truth, are the senses and consciousness. With regard to all general propositions, the faculty of discovering what in this case is meant by truth is merely the faculty by which we trace the meaning of words.

Having thus seen by what course Mr. Stewart might very easily have arrived at the goal at which he professedly aimed, let us next contemplate as briefly as our limits constrain us, the course which he has actually pursued.

In this first chapter, he treats of what he calls, "The fundamental laws of human belief; or the primary elements of human reason." This seems to be intended for the account of what he also calls, "The power by which we distinguish truth from false hood," adding, "and combine means for the attainment of our ends." In the second chapter, he treats of "Reasoning and Deductive evidence," that is, ratiocination, in the common acceptation of the term. The third chapter treats of the Aristotelian logic, that is, a mere instrument of ratiocination; in propriety of arrangement, therefore, this chapter ought to have formed only a section of the former. The fourth and last chapter treats of the inductive logic, or the method of inquiry, pursued in the experimental philosophy. Attending to the nature of the subject, we shall perceive, that he thus treats in the first chapter, of what has been called the intuitive, or immediate recognition of truth; and in the three last, of its discovery by the intervention of proof, in which there are distinguishable two modes, the ratiocinative and inductive. It is to be observed that it is general, in other words, verbal propositions and reasonings, what the author has in view thoughout almost the whole of this voluminous inquiry; and that he endeavours to explain what takes place in the mind, without adverting (except casually, and in such a manner as by no means to give a turn to the current of his thoughts) to his own doctrine, that all affirmation and all reasoning, in general terms, are only recognizing, or tracing the connection between, different expressions of the same thing.

In the first chapter, he treats of two things; first, of mathematical axioms; secondly, of what he calls, "Certain laws of belief, inseparably connected with the exercise of consciousness, memory, perception, and reasoning." Mathematical axioms are here introduced, only for the purpose of stating certain opinions which help to lay the foundation of that account of the nature of mathematical evidence, which Mr. Stewart endeavours to esta blish in the second chapter. To this account, we fear, it will not be in our power to advert, however desirous we may be to develope some fundamental error which it appears to us to involve, We shall therefore postpone any remarks which we may have to offer on what Mr. Stewart advances on the subject of axioms, till we see whether we can find room for any of our criticisms on the subsequent disquisition, to which his observations on axioms more immediately refer.

In the two sections in which he treats of "certain laws of belief," &c. we are peculiarly interested; because, by these laws of belief, he means the instinctive principles of Dr. Reid, We are anxious, therefore, to discover, whether he has brought any new lights to aid in showing that they are entitled to govern our belief; or whether he has left that important point as destitute of proof as he received it from Reid; and hence the scepticism of Berkeley and Hume as little provided, even at this day, with an antidote, as it was at the time of its first publication,

He begins with mind-belief in the existence of mind. He allows that mind is not an object of consciousness. "We are conscious," he says, "of sensation, thought, desire, volition; but we are not conscious of the existence of mind itself." He proceeds next, to the belief of personal ideality. "That we cannot, without a very blameable latitude in the use of words, be said to be conscious of our personal identity, is a proposition," he affirms, "still more indisputable."

66

Whence then is this belief-belief in the existence of mind, and belief in our personal identity, derived? This belief," says Mr. Stewart," is involved in every thought and every action of the mind, and may be justly regarded as one of the simplest and most essential elements of the understanding. Indeed it is impossible to conceive either an intellectual or active being to exist without it."

From belief in the existence of mind, and belief of personal identity, where Mr. Stewart passes to the material world, he only says, "The belief which all men entertain of the existence of the material world, and their expectation of the continued uniformity of the laws of nature, belong to the same class of ultimate or elemental laws of thought, with those which have just been mentioned." "These different truths," he says, "all agree

in this, that they are essentially involved in the exercise of our rational powers."

If Mr. Stewart has adduced any evidence to establish the belief of these truths, we may venture to affirm without dreading contradiction, that it is all included, to the last item, in the quotations which the last two paragraphs present. "This belief," says he, "is involved in every thought and every action of the mind." But what does he mean by this metaphorical, mysterious, and hence, we venture to add, unphilosophical use of the word "involved?" Every act of consciousness appears to us to be simple, one, and individual. To talk of one act of consciousness as involved, that is, wrapt up in another, having another rolled round it, we cannot help regarding as that sort of jargon which an ingenious man uses only when he is placed in that unhappy situation in which he still clings to a favourite notion, without having any thing plausible to adduce in its defence. If he had affirmed that the belief of the existence of mind and of personal identity is conjoined with every act of consciousness, that is, immediately precedes, or immediately follows it, we should at least have conceived what he meant. And all which then would have remained for us to do, would have been to ask him for the proof of his assertion.

We may suppose that this is the meaning of the ill-timed metaphor; because, as far as we are able to discover, it is the only intelligible meaning which can be assigned to it, and we do ask, what evidence of the assertion Mr. Stewart has adduced? The answer is, that he has adduced none whatsoever. He has added his ipse dixit to that of Dr. Reid; and upon that foundation, as far as they are concerned, the matter rests. In truth, the language of Mr. Stewart is far more unguarded and exceptionable, than that of Dr. Reid. That philosopher only affirmed that we had the belief, without affirming that it accompanied every mental operation, which we apprehend is by no means the fact. If we interpret justly what we are conscious of in ourselves, the operations of the mind, in their ordinary and habitual train, have no such accompaniment; and we never think of the existence of our mind and our personal identity, but when some particular occasion suggests it as an object of reflection."

He calls it "an essential element of the understanding;" in another place, he gives what he calls "this class of truths," the distinctive name of 66 primary elements of human reason;" in a succeeding passage he says, they enter as essential elements into the composition of reason itself.”

66

Mr. Stewart defines reason, in the sense in which he professes exclusively to use it, to be "the power by which we distinguish truth from falsehood." Now, not to speak of the difficulty we

find in conceiving a compound power of the mind, a power made up of parts or ingredients, we may venture to assert, that if there be such a thing as a compound power of the mind, it must be a power made up of a union of several simple powers: into the composition of a power, nothing can enter that is essentially not a power. What then shall we say of the belief in the existence of body and mind? Is that a power? Or is it any thing more than one particular act of power, the power of believing? But what kind of a proposition is that which affirms, that a particular act of one power enters into the composition of another power?

Mr. Stewart says, "It is impossible to conceive either an intellectual or an active being to exist without the belief of the existence of its own mind, and the belief of its personal identity." When a man uses the expression, "it is impossible to conceive," it never means, and never can mean, any thing else than that he disbelieves strongly that which is the object of the affirmation. It is, therefore, only one of the garbs in which ipse dixit enrobes itself. But when we are in the search of reasons, ipse dixit is far from an advantage; and the more ingenious the colours in which it clothes itself, the evil is still the greater. Mr. Stewart seems, also, not to be aware, that in the very terms, "an intellectual or active being," there is an implied petitio principii. According to the terms of the question, the existence of such a being is the very point to be proved. Whether a being, the subject of sensation and consciousness, can be, or cannot be, without a belief of its own existence, is more than we can venture to affirm; but surely a train of sensations and reflections, which is Hume's hypothesis, may be conceived to exist, into which train the belief of matter and of mind does not enter as a part. The curious circumstance is, that on the preceding page, Mr. Stewart himself says, "We are conscious of sensation, thought, desire, volition; but we are not conscious of the existence of mind itself; nor would it be possible for us to arrive at the knowledge of it, (supposing us to be created in the full possession of all the intellectual capacities which belong to human nature,) if no impression were ever to be made on our external senses.'

Another of his favourite phrases is, that "the truths" in question" are fundamental laws of human belief.", We need hardly renew the remark, that this is only another bold assertion, in which that is assumed which ought to be proved; a species of conduct in which a man exerts an act, not of reason, but of despotism, commanding all men, on pain of his condemnation, to believe as he does. The phrase however is, on other grounds, highly objectionable. There is even a species of absurdity in calling a truth a law of belief. A truth is an object of belief. An object of belief cannot be a law. It may be agreeable
