a faculty of the soul whereby it perceives external objects by means of the impressions they make on certain organs of the body. See Metaphysics, Part I. and Anatomy, n° 137, &c.

Common Sense, is a term that has been variously used both by ancient and modern writers. With some it has been synonymous with public sense; with others it has denoted prudence; in certain instances, it has been confounded with some of the powers of taste; and, accordingly, those who commit egregious blunders with regard to decorum, saying and doing what is offensive to their company, and inconsistent with their own character, have been charged with a defect in common sense. Some men are distinguished by an uncommon acuteness in discovering the characters of others; and this talent has been sometimes called common sense; similar to which is that use of the term, which makes it to signify that experience and knowledge of life which is acquired by living in society. To this meaning Quintilian refers, speaking of the advantages of a public education: Sentum ipsum qui communis dictur, ubi disset, cum se a congruiss, qui non hominibus solum, sed mutis quoque animalibus naturalis est, segregari? Lib. i. cap. 2.

But the term common sense hath in modern times been used to signify that power of the mind which perceives truth, or commands belief, not by progressive argumentation, but by an instantaneous, instinctive, and irresistible impulse; derived neither from education nor from habit, but from nature; acting independently of our will, whenever its object is presented, according to an established law, and therefore called sense; and acting in a similar manner upon all, or at least upon a great majority of mankind, and therefore called common sense. See Metaphysics, n° 127.

Moral Sense, is a determination of the mind to be pleased with the contemplation of those affections, actions, or characters, of rational agents, which we call good or virtuous.

This moral sense of beauty in actions and affections may appear strange at first view: some of our moralists themselves are offended at it in Lord Shaftesbury, as being accustomed to deduce every approbation or aversion from rational views of interest. It is certain that his Lordship has carried the influence of the moral sense very far, and some of his followers have carried it farther. The advocates for the selfish system seem to drive their opinions to the opposite extreme, and we have elsewhere endeavoured to show that the truth lies between the contending parties. See Moral Philosophy, n° 27,--32.

Public Sense is defined by the noble author of the Characteristics to be an innate propensity to be pleased with the happiness of others, and to be uneasy at their misery. It is found, he says, in a greater or less degree in all men, and was sometimes called societas, or social community, by ancient writers.

Of the reality of this public sense we have great doubts. The conduct of savages, who are more under the influence of original instinct than civilized men, gives no countenance to it. Their affections seem all to be selfish, or at least to spring from self-love variously modified. For the happiness of their wives they have very little regard, considering them merely as instruments of their own pleasure, and valuing them for nothing else. Hence they make them toil, while they themselves indulge in littlest idleness. To their children we believe they exhibit strong symptoms of attachment, as soon as they derive assistance from them in war, or in the business of the chase; but during the helpless years of infancy, the child is left by the selfish father wholly to the care and protection of its wretched mother, who, impelled by the florgé of all females to their young, cherishes her offspring with great fondness. The savage is, indeed, susceptible of strong attachments, similar to that which we call friendship; but such attachments are no proofs of disinterested benevolence, or what his Lordship calls the public sense. Two barbarous heroes are probably first linked together by the observation of each other's prowess in war, or their skill in pursuing their game; for such observation cannot fail to show them that they may be useful to one another; and we have elsewhere shown how real friendship may spring from sentiments originally selfish. The savage is very much attached to his horde or tribe, and this attachment resembles patriotism; but patriotism itself is not a sentiment of pure benevolence delighting in the happiness of others, and grieving at their misery; for the patriot prefers his own country to all others, and is not very scrupulous with respect to the rectitude of the means by which he promotes its interest, or depresses its rivals. The savage pursues with relentless rigour the enemies of himself or of the tribe to which he belongs; shows no mercy to them when in his power, but puts them to the cruellest death, and carries their scalps to the leader of his party. These facts, which cannot be controverted, are perfectly irreconcilable with innate benevolence, or a public sense comprehending the whole race of men; and show the truth of that theory by which we have in another place endeavoured to account for all the passions, social as well as selfish. See Passion.

SENSIBLE NOTE, in music, is that which constitutes a third major above the dominant, and a semi-tone. SEN

Sensibility tone beneath the tonic. Si, or B, is the sensible note in the tone of ut or C sol *; or G sharp, in the tone of la or A.

They call it the sensible note on this account, that it causes to be perceived the tone or natural series of the key and the tonic itself; upon which, after the chord of the dominant, the sensible note taking the shortest road, is under a necessity of rising; which has made some authors treat this sensible note as a major dissonance, for want of observing, that dissonance, being a relation, cannot be constituted unless by two notes between which it subsists.

It is not meant that the sensible note is the seventh of the tone, because, in the minor mode, this seventh cannot be a sensible note but in ascending; for, in descending, it is at the distance of a full note from the tonic, and of a third minor from the dominant.
