oppressed--an d if each feeling it in himself, they all say so with one
voice and one heart, and lift up their hands to second their appeal,
this I should say was but the dictate of common sense, the cry of
nature. But to waive this part of the argument, which it is needless to
push farther,--l believe that the best way to instruct mankind is not by
pointing out to them their mutual errors, but by teaching them to think
rightly on indifferent matters, where they will listen with patience in
order to be amused, and where they do not consider a definition or a
syllogism as the greatest injury you can offer them.

There is no rule for expression. It is got at solely by _feeling_, that
is, on the principle of the association of ideas, and by transferring
what has been found to hold good in one case (with the necessary
modifications) to others. A certain look has been remarked strongly
indicative of a certain passion or trait of character, and we attach the
same meaning to it or are affected in the same pleasurable or painful
manner by it, where it exists in a less degree, though we can define
neither the look itself nor the modification of it. Having got the
general clue, the exact result may be left to the imagination to vary,
to extenuate or aggravate it according to circumstances. In the
admirable profile of Oliver Cromwell after ----, the drooping eyelids,
as if drawing a veil over the fixed, penetrating glance, the nostrils
somewhat distended, and lips compressed so as hardly to let the breath
escape him, denote the character of the man for high-reaching policy and
deep designs as plainly as they can be written. How is it that we
decipher this expression in the face? First, by feeling it. And how is
it that we feel it? Not by re-established rules, but by the instinct of
analogy, by the principle of association, which is subtle and sure in
proportion as it is variable and indefinite. A circumstance, apparently
of no value, shall alter the whole interpretation to be put upon an
