experiment. If scientific law is declared experimentally, the course of
nature is modified by intent; certain conditions are secured, certain
others eliminated; a selected train of phenomena is then set in motion
to the end that the law may be illustrated, and nothing else. In a
perfect experiment the law is in full operation. In plot there is a like
selection of persons, situations, and incidents so arranged as to
disclose the working of that order which obtains in man's life. The law
may be simple and shown by means of few persons and incidents in a brief
way, as in ancient drama, or complex and exhibited with many characters
in an abundance of action over a wide scene as in Shakspere; in either
case equally there is a selection from the whole mass of man's life of
what shall illustrate the causal union in its order and show it in
action. The process in the epic or prose narrative is the same. The
common method of all is to present the universal law in a particular
instance made for the purpose.

In thus clothing itself in concrete form, truth suffers no
transformation; it remains what it was, general truth, the very essence
of type and plot being, as has been said, to preserve this universality
in the particular instance. There is a sense in which this general truth
is more real, as Plato thought, than particulars; a sense in which the
phenomenal world is less real than the system of nature, for phenomena
come and go, but the law remains; a sense in which the order in man's
breast is more real than he is, in whom it is manifest, for the form of
ideas, the mould of law, are permanent, but their expression in us
transitory. It is this higher realism, as it was anciently called, that
the mind strives for in idealism,--this organic form of life, the object
of all rational knowledge. Types, under their concrete disguise, are
thus only a part of the general notions of the mind found in every
branch of knowledge and necessary to thought; plots, similarly, are only
