The odd manner in which Mr. Mill worships mere variety, and confounds the proposition that variety is good with the proposition that goodness is various, is well illustrated by the lines which follow this passage:-- "Exceptional individuals ... should be encouraged in acting differently from the mass" --in order that there may be enough of them to "point out the way." Eccentricity is much required in these days. Precisely because the tyranny of opinion is such as to make eccentricity a reproach, it is desirable, in order to break through that tyranny, that people should be eccentric. Eccentricity has always abounded when and where strength of character has abounded, and the amount of eccentricity in a society has generally been proportioned to the amount of genius, mental vigour, and moral courage it contained. That so few now dare to be eccentric makes the chief danger of the time.
If this advice were followed, we should have as many little oddities in manner and behaviour as we have people who wish to pass for men of genius. Eccentricity is far more often a mark of weakness than a mark of strength. Weakness wishes, as a rule, to attract attention by trifling distinctions, and strength wishes to avoid it. Originality consists in thinking for yourself, not in thinking differently from other people.
