Read it through once

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.
