A man of intellect is like an artist who gives a concert without any
help from anyone else, playing on a single instrument--a piano, say,
which is a little orchestra in itself. Such a man is a little world in
himself; and the effect produced by various instruments together, he
produces single-handed, in the unity of his own consciousness. Like
the piano, he has no place in a symphony: he is a soloist and performs
by himself,--in solitude, it may be; or, if in company with other
instruments, only as principal; or for setting the tone, as in
singing. However, those who are fond of society from time to time
may profit by this simile, and lay it down as a general rule that
deficiency of quality in those we meet may be to some extent
compensated by an increase in quantity. One man's company may be quite
enough, if he is clever; but where you have only ordinary people to
deal with, it is advisable to have a great many of them, so that
some advantage may accrue by letting them all work together,--on the
analogy of the horns; and may Heaven grant you patience for your task!

That mental vacuity and barrenness of soul to which I have alluded, is
responsible for another misfortune. When men of the better class form
a society for promoting some noble or ideal aim, the result almost
always is that the innumerable mob of humanity comes crowding in too,
as it always does everywhere, like vermin--their object being to try
and get rid of boredom, or some other defect of their nature; and
anything that will effect that, they seize upon at once, without the
slightest discrimination. Some of them will slip into that society,
or push themselves in, and then either soon destroy it altogether, or
alter it so much that in the end it comes to have a purpose the exact
opposite of that which it had at first.
