as well as those deadly outrages which are inflicted by a look, a word--or less--the very refraining from some faint and most evanescent expression of countenance; these flow from a profounder source than the series of our habitual conduct, which, it has been already said, derives its origin from without. These are the actions, and such as these, which make human life what it is, and are the fountains of all the good and evil with which its entire surface is so widely and impartially overspread; and though they are called minute, they are called so in compliance with the blindness of those who cannot estimate their importance. It is in the due appreciating the general effects of their peculiarities, and in cultivating the habit of acquiring decisive knowledge respecting the tendencies arising out of them in particular cases, that the most important part of moral science consists. The deepest abyss of these vast and multitudinous caverns, it is necessary that we should visit. This is the difference between social and individual man. Not that this distinction is to be considered definite, or characteristic of one human being as compared with another; it denotes rather two classes of agency, common in a degree to every human being. None is exempt, indeed, from that species of influence which affects, as it were, the surface of his being, and gives the specific outline to his conduct. Almost all that is ostensible submits to that legislature created by the general representation of the past feelings of mankind--imperfect as it is from a variety of causes, as it exists in the government, the religion, and domestic habits. Those who do not nominally, yet actually, submit to the same power. The external features of their conduct, indeed, can no more escape it, than the clouds can escape from the stream of the wind; and his opinion, which he often hopes he has dispassionately secured from all contagion of prejudice and vulgarity, would be found, on examination, to be the inevitable excrescence of the very usages from which he vehemently dissents. Internally all is conducted otherwise; the efficiency, the essence, the vitality of actions, derives its colour from what is no ways contributed to from any external source. Like the plant which while it derives the accident of its size and shape from the soil in which it springs, and is cankered, or distorted, or inflated, yet retains those qualities which essentially divide it from all others; so that hemlock continues to be poison, and the violet does not cease to emit its odour in whatever soil it may grow. We consider our own nature too superficially. We look on all that in ourselves with which we can discover a resemblance in others; and consider those resemblances as the materials of moral knowledge. It is in the differences that it actually consists. [1815; publ. 1840] ESSAY ON THE LITERATURE, THE ARTS, AND THE MANNERS OF THE ATHENIANS A FRAGMENT
