, of which the impression produced is the expression.
Accordingly our knowledge is not enlarged by judgments of taste, and no
knowledge, not even that of beauty, is obtained by the feeling of beauty.
Therefore, when knowledge is the object, taste can give us no help, at
least directly and immediately; on the contrary, knowledge is shut out as
long as we are occupied with beauty.

But it may be objected, What is the use then of a graceful embodiment of
conceptions, if the object of the discussion or treatise, which is simply
and solely to produce knowledge, is rather hindered than benefited by
ornament? To convince the understanding this gracefulness of clothing
can certainly avail as little as the tasteful arrangement of a banquet
can satisfy the appetite of the guests, or the outward elegance of a
person can give a clue to his intrinsic worth. But just as the appetite
is excited by the beautiful arrangement of the table, and attention is
directed to the elegant person in question, by the attractiveness of the
exterior, so also we are placed in a favorable attitude to receive truth
by the charming representation given of it; we are led to open our souls
to its reception, and the obstacles are removed from our minds which
would have otherwise opposed the difficult pursuit of a long and strict
concatenation of thought. It is never the contents, the substance, that
gains by the beauty of form; nor is it the understanding that is helped
by taste in the act of knowing. The substance, the contents, must
commend themselves to the understanding directly, of themselves; whilst
the beautiful form speaks to the imagination, and flatters it with an
appearance of freedom.

But even further limitations are necessary in this innocent subserviency
to the senses, which is only allowed in the form, without changing
anything in the substance. Great moderation must be always used, and
sometimes the end in view may be completely defeated according to the
kind of knowledge and degree of conviction aimed at in imparting our
views to others. There is a scientific knowledge, which is based on
clear conceptions and known principles; and a popular knowledge, which is
founded on feelings more or less developed. What may be very useful to
the latter is quite possibly adverse to the former.

When the object in view is to produce a strict conviction on principles,
it is not sufficient to present the truth only in respect to its contents
or subject;
