the three forms
of diction. Generally it may be laid down as a rule that preference
ought to be given to the scientific style whenever the chief
consideration is not only the result, but also the proofs. But when the
result merely is of the most essential importance the advantage must be
given to popular elocution and fine language. But it may be asked in
what cases ought popular elocution to rise to a fine, a noble style?
This depends on the degree of interest in the reader, or which you wish
to excite in his mind.

The purely scientific statement may incline either to popular discourse
or to philosophic language, and according to this bias it places us more
or less in possession of some branch of knowledge. All that popular
elocution does is to lend us this knowledge for a momentary pleasure or
enjoyment. The first, if I may be allowed the comparison, gives us a
tree with its roots, though with the condition that we wait patiently for
it to blossom and bear fruit. The other, or fine diction, is satisfied
with gathering its flowers and fruits, but the tree that bore them does
not become our property, and when once the flowers are faded and the
fruit is consumed our riches depart. It would therefore be equally
unreasonable to give only the flower and fruit to a man who wishes the
whole tree to be transplanted into his garden, and to offer the whole
tree with its fruit in the germ to a man who only looks for the ripe
fruit. The application of the comparison is self-evident, and I now only
remark that a fine ornate style is as little suited to the professor's
chair as the scholastic style to a drawing-room, the pulpit, or the bar.

The student accumulates in view of an ulterior end and for a future use;
accordingly the professor ought to endeavor to transmit the full and
entire property of the knowledge that he communicates to him. Now,
nothing belongs to us as our own but what has been communicated to the
understanding. The orator, on the other hand, has in view an immediate
end, and his voice must correspond with an immediate want of the public.
His interest is to make his knowledge practically available as soon as
possible; and the surest way is to hand it over to the senses, and to
prepare it for the use of sensation. The professor, who only admits
hearers on certain conditions, and who is entitled to suppose in his
hearers the dispositions of mind in which a man ought to be to receive
the truth, has only in view in
