time, it can never have any, since all the ideas we know of consist of more than one: and though the consciousness we have of attending to different objects at once, when we compare, judge, reason, will, &c., has been resolved into a deception of the mind in mistaking a rapid succession of objects for one general impression, yet it will hardly be pretended that we deceive ourselves in thinking we have any ideas at all. Mr Horne Tooke, who is certainly one of the ablest commentators on the doctrines of that school, says that it is as absurd to talk of a complex idea as of a complex star, meaning that our ideas are as perfectly distinct from, and have as little to do with one another, as the stars that compose a constellation. Other writers, to avoid the seeming contradiction of supposing the mind to divide its attention between different objects, have suggested the instant of its passing from one to the other as the true point of comparison between them; or that the time when it had an idea of both together, was the time when it had an idea of neither. As it was evident that while the mind was entirely taken up with one idea, it could not have any knowledge of another which did not yet exist, or had passed away, and as both impressions cannot be supposed to co-exist in the same conscious understanding

(for on this system there is no such faculty), this short, precious interval, this moment of leisure from both, this lucky vacancy of thought, is pitched upon as that in which the mind performs all its functions, and contemplates its various ideas in their absence, as from some vantage ground the traveller stops to survey the country on both sides of him. To such absurdities are ingenious men driven by setting up argument against fact, and denying the most obvious truths for which they cannot account, like the sophist who denied the existence of motion, because he could not understand its nature. It might be deemed a sufficient answer to those who build systems and lay down formal propositions on the principle that the mind can comprehend but one idea at a time, to say that they consequently can have no meaning in what they write, since when they begin a sentence they cannot have the least idea of what will be the end of it, and by the time they get to the end of it must totally forget the beginning. "Peace to all such!"

To show, however, that I am not quite singular in my notions on this subject of consciousness, and to remove, as I think, every shadow of doubt upon it, I beg leave to refer my readers to two passages, the one in Rousseau,

and the other in Abraham Tucker, in support of the almost obsolete prejudice which I have here endeavoured to defend. The one is an argument to prove that judgment and sensation are not the same, in the Vicar's profession of faith in Emilius,' and the other is the chapter on the independent existence of mind in the Light of Nature Pursued.'

The passage in Rousseau seems evidently to have been intended as an answer to the maxim of Helvetius that to feel is to judge, and to his reasoning on this maxim, which is as follows:

"The question being reduced within these limits, I shall examine at present whether the act of the mind in judging is any thing more than a sensation. When I judge of the size or colour of the objects around me, it is evident that the judgment formed of the different impressions, which these objects make upon my senses, is properly only a sensation that I may say indiscriminately, either I judge, or I feel, that of two objects, the one which I call a yard makes upon me a different impression from another which I call a foot: that the colour called red, produces a different effect upon the sight from that which I call yellow; and I conclude that in this case to judge is only to feel or perceive by the senses. But it may be said, let

us suppose that any one desires to know whether strength of body is preferable to mere bulk; are we certain that we can decide this point by means of the senses alone? Most undoubtedly, I reply for in order to my coming to a decision on the subject, my memory must first retrace to me successively the different situations in which I may happen most frequently to find myself in the course of my life. In this case, then, to judge is to see that in these different situations. strength will be oftener an advantage to me than size. But it may be retorted, when the question is to decide whether in a king justice is preferable to mercy, is it conceivable that the conclusion here formed depends entirely on sensation? The affirmative has undoubtedly at first sight the air of a paradox: nevertheless, in order to establish its truth, we will presuppose in any one a knowledge of what is meant by good and evil, and also of the principle that one action is worse than another, according as it is more injurious to the well-being of society. On this supposition, what method ought the orator or poet to take, in order to show most clearly that justice, preferable in a king to mercy, preserves the greatest number of citizens to the state?

"The orator will present three several pictures to the imagination of his supposed hearer: in

the first he will represent a just king, who condemns and gives orders for the execution of a criminal; in the second, will be seen the good king, who opens the doors of his dungeon, and strikes off the chains of the same criminal; in the third picture, the criminal himself will be the principal figure, who, armed with a poniard, on his escape from his cell hastens to assassinate fifty of his fellow-citizens. But who is there that at the sight of these three pictures will not instantly perceive that justice, which, by the death of a single individual, saves the lives of fifty persons, is preferable to mercy? Nevertheless, this judgment is really nothing but a sensation. In fact, if from the habit of connecting certain ideas with certain words, the sound of these words may, as experience demonstrates, excite in us almost the same sensations which we should feel from the actual presence of the objects, it is evident that from the contemplation of these three pictures, to judge that in a king justice is preferable to mercy, is to feel and see that in the first picture a single citizen is sacrificed, while in the third fifty are massacred; whence I conclude that every act of the judgment is only a sensation.”—Helvetius on the Mind, p. 12.
