best that is known and thought in the world," and its more ultimate
purpose is "to keep man from a self-satisfaction which is retarding and
vulgarizing, to lead him towards perfection." It is not to be confined
to art and literature, but is to include within its scope society,
politics, and religion. It is not only to censure that which is
blameworthy, but to appreciate and popularize the best.

For this work great virtues are demanded of the critic. Foremost of
these is disinterestedness. "If I know your sect, I anticipate your
argument," says Emerson in the essay on _Self-Reliance_. Similarly
Arnold warns the critic against partisanship. It is better that he
refrain from active participation in politics, social or humanitarian
work. Connected with this is another requisite, that of clearness of
vision. One of the great disadvantages of partisanship is that it blinds
the partisan. But the critical effort is described as "the effort to see
the object as in itself it really is." This is best accomplished by
approaching truth in as many ways and from as many sides as possible.

Another precaution for the critic who would retain clearness of vision
is the avoidance of abstract systems, which petrify and hinder the
necessary flexibility of mind. Coolness of temper is also enjoined and
scrupulously practiced. "It is only by remaining collected ... that the
critic can do the practical man any service"; and again: "Even in one's
ridicule one must preserve a sweetness and good humor" (letter to his
mother, October 27, 1863). In addition to these virtues, which in
Arnold's opinion comprised the qualities most requisite for salutary
criticism, certain others are strikingly illustrated by Arnold's own
mind and methods: the endeavor to understand, to sympathize with, and to
guide intelligently the main tendencies of his age, rather than
violently to oppose them; at the same time the courage to present
