* very celebrated work the following passage from Picus Mirandula : Movent mihi stomachum grammatistæ quidam, qui cum duas tenuerint vocabulorum origines, ita se ostentant, ita venditant, ita circumferunt jactabundi, ut præ ipsis pro nihilo habendos philosophos arbitrentur. Epist. ad Hermol. Barb. MOTIVES AND IMPULSES. It is a matter of infinite difficulty, but fortunately of comparative indifference to determine what a man's motive may have been for this or that particular action. Rather seek to learn what his objects in general are. What does he habitually wish, habitually pursue? and thence deduce his impulses which are commonly the true efficient causes of men's conduct; and without which the motive itself Iwould not have become a motive. Let a haunch of venison represent the motive, and the keen appetite of health, and exercise the impulse then place the same or some more favourite dish before the same man, sick, dyspeptic, and stomach-worn, and we may then weigh the comparative influences of motives and impulses. Without the perception of this truth, it is impossible to understand the character of Iago, who is represented as now assigning one, and then another, and again a * Diversions of Purley. Ed. third motive for his conduct, all alike the mere fictions of his own restless nature, distempered by a keen sense of his intellectual superiority, and haunted by the love of exerting power on those especially who are his superiors in practical and moral excellence. Yet how many among our modern critics have attributed to the profound author this the appropriate inconsistency of the character itself. A second illustration:- Did Curio, the quondam patriot, reformer, and semi-revolutionist, abjure his opinion, and yell the foremost in the hunt of persecution against his old friends and fellow-philosophists, with a cold clear predetermination, formed at one moment, of making £5000 a year by his apostacy?—I neither know nor care. Probably not. But this I know, that to be thought a man of consequence by his contemporaries, to be admitted into the society of his superiors in artificial rank, to excite the admiration of lords, to live in splendour and sensual luxury, have been the objects of his habitual wishes. A flash of lightning has turned at once the polarity of the compass needle and so, perhaps, now and then, but as rarely, a violent motive may revolutionize a man's opinions and professions. But more frequently his honesty dies away imperceptibly from evening into twilight, and from twilight into utter darkness. He turns hypocrite so gradually, and by such tiny atoms of motion, that by the time he has arrived at a given point, he forgets his own hypocrisy in the imperceptible degrees of his conversion. The difference between such a man and a bolder liar, is merely that between the hour hand, and that which tells the seconds, on a watch. Of the former you can see only the past motion; of the latter both the past motion and the present moving. Yet there is, perhaps, more hope of the latter rogue: for he has lied to mankind only and not to himself—the former lies to his own heart, as well as to the public. INWARD BLINDNESS. TALK to a blind man-he knows he wants the sense of sight, and willingly makes the proper allowances. But there are certain internal senses, which a man may want, and yet be wholly ignorant that he wants them. It is most unpleasant to converse with such persons on subjects of taste, philosophy, or religion. Of course there is no reasoning with them: for they do not possess the facts, on which the reasoning must be grounded. Nothing is possible, but a naked dissent, which implies a sort of unsocial contempt; or, what a man of kind dispositions is very likely to fall into, a heartless tacit acquiescence, which borders too nearly on duplicity. THE VICES OF SLAVES NO EXCUSE FOR SLAVERY. IT often happens, that the slave himself has neither the power nor the wish to be free. He is then brutified; but this apathy is the dire effect of slavery, and so far from being a justifying cause, that it contains the grounds of its bitterest condemnation. The Carlovingian race bred up the Merovingi as beasts; and then assigned their unworthiness as the satisfactory reason for their dethronement. Alas! the human being is more easily weaned from the habit of commanding than from that of abject obedience. The slave loses his soul when he loses his master; even as the dog that has lost himself in the street, howls and whines till he has found the house again, where he had been kicked and cudgelled, and half starved to boot. As we, however, or our ancestors must have inoculated our fellow-creature with this wasting disease of the soul, it becomes our duty to cure him; and though we cannot immediately make him free, yet we can, and ought to, put him in the way of becoming so at some future time, if not in his own person, yet in that of his children. The French, you will say, are not capable of freedom. Grant this ;--but does this fact justify the ungrateful traitor, whose every measure has been to make them still more incapable of it? CIRCULATION OF THE BLOOD. THE ancients attributed to the blood the same motion of ascent and descent which really takes place in the sap of trees. Servetus discovered the minor circulation from the heart to the lungs. Do not the following passages of Giordano Bruno (published in 1591) seem to imply more? I put the question, pauperis forma, with unfeigned diffidence. "De Immenso et Innumerabili," lib. vi. cap. 8.

Quare non aliter quam nostro in corpore sanguis and still more plainly, in the ninth chapter of the same book, Quid esset Quodam ni gyro naturæ cuncta redirent It is affirmed in the "Supplement to the Scotch Encyclopædia Britannica," that Des Cartes was the first who in defiance of Aristotle and the Schools, attributed infinity to |
