ELEMENTS OF THE PHILOSOPHY OF THE HUMAN MIND. PART SECOND. OF REASON, OR THE UNDERSTANDING PROPERLY SO CALLED; AND THE VARIOUS FACULTIES AND OPERATIONS MORE IMMEDIATELY CONNECTED WITH IT. PRELIMINARY OBSERVATIONS ON THE VAGUENESS AND AMBIGUITY OF THE COMMON PHILOSOPHICAL LANGUAGE RELATIVE TO THIS PART OF OUR CONSTITUTION. REASON AND REASONING, UNDERSTANDING, THE HE power of Reason, of which I am now to treat, is unquestionably the most important by far, of those which are comprehended under the general title of Intellectual. It is on the right use of this power, that our success in the pursuit both of knowledge and of happiness depends; and it is by the exclusive possession of it that Man is distinguished, in the most essential respects, from the lower animals. It is, indeed, from their subserviency to its operations, that the other faculties, which have been hitherto under our consideration, derive their chief value. In proportion to the peculiar importance of this subject are its extent and its difficulty ;-both of them such as to lay me under a necessity, now that I am to enter on the discussion, to contract," in various instances, those designs in which I was accustomed to indulge myself, when I looked forward to it from a distance. The execution of them at present, even if I were more competent to the task, appears to me, on a closer examination, to be altogether incompatible with the comprehensiveness of the general plan which was sketched out in the advertisement prefixed to the former volume; and to the accomplishment of which I am anxious, in the first instance, to direct my efforts. If that undertaking should ever be completed, I may perhaps be able afterwards to offer additional illustrations of certain articles, which the limits of this part of my work prevent me from considering with the attention which they deserve. I should wish, in particular, to contribute something more than I can here introduce, towards a rational and practical system of Logic, adapted to the present state of human knowledge, and to the real business of human life. "What subject (says Burke) does not branch out to infinity! "It is the nature of our particular scheme, and the single point "of view in which we consider it, which ought to put a stop "to our researches." How forcibly does the remark apply to Conclusion of the Inquiry into the Sublime and the Beautiful. all those speculations which relate to the principles of the Human Mind! I have frequently had occasion, in the course of the foregoing disquisitions, to regret the obscurity in which this department of philosophy is involved, by the vagueness and ambiguity of words; and I have mentioned, at the same time, my unwillingness to attempt verbal innovations, wherever I could possibly avoid them, without essential injury to my argument. The rule which I have adopted in my own practice is, to give to every faculty and operation of the mind its own appropriate name; following, in the selection of this name, the prevalent use of our best writers; and endeavouring afterwards, as far as I have been able, to employ each word exclusively, in that acceptation in which it has hitherto been used most generally. In the judgments which I have formed on points of this sort, it is more than probable that I may sometimes have been mistaken; but the mistake is of little consequence, if I myself have invariably annexed the same meaning to the same phrase ; -an accuracy which I am not so presumptuous as to imagine that I have uniformly attained, but which I am conscious of having, at least, uniformly attempted. How far I have succeeded, they alone who have followed my reasonings with a very critical attention are qualified to determine; for it is not by the statement of formal definitions, but by the habitual use of precise and appropriate language, that I have endeavoured to fix in my reader's mind the exact import of my expressions. In appropriating, however, particular words to particular ideas, I do not mean to censure the practice of those who may have understood them in a sense different from that which I annex to them; but I found that, without such an appropriation, I could not explain my notions respecting the human mind, with any tolerable degree of distinctness. This scru pulous appropriation of terms, if it can be called an innovation, is the only one which I have attempted to introduce; for in no instance have I presumed to annex a philosophical meaning to a technical word belonging to this branch of science, without having previously shewn, that it has been used in the same sense by good writers, in some passages of their works. After doing this, I hope I shall not be accused of affectation, when I decline to use it in any of the other acceptations in which, from carelessness or from want of precision, they may have been led occasionally to employ it. Some remarkable, instances of vagueness and ambiguity in the employment of words, occur in that branch of my subject of which I am now to treat. The word. Reason itself is far from being precise in its meaning. In common and popular discourse, it denotes that power by which we distinguish truth from falsehood, and right from wrong; and by which we are enabled to combine means for the attainments of particular ends. Whether these different capacities are, with strict logical propriety, referred to the same power, is a question which I shall examine in another part of my work; but that they are all included in the idea which is generally annexed to the word reason, there can be no doubt; and the case, so far as I know, is the same with the corresponding term in all languages whatever. The fact probably is, that this word was first employed |
