It seems reasonable to expect
that a great dramatick poet should, without difficulty, become a great
actor; that he who can feel, should express; that he who can excite
passion, should exhibit, with great readiness, its external modes: but
since experience has fully proved, that of those powers,           be
their affinity, one may be possessed in a great degree by him who has
very little of the other; it must be allowed that they depend upon
different faculties, or on different use of the same faculty; that the
actor must have a pliancy of mien, a flexibility of countenance, and a
variety of tones, which the poet may be easily supposed to want; or that
the attention of the poet and the player has been differently employed;
the one has been considering thought, and the other action; one has
watched the heart, and the other contemplated the face.
