observation, we may gather in some measure in what manner those we are acquainted with express their passions externally. But with respect to strangers, of whom we have no experience, we are left in the dark. And yet we are not puzzled about the meaning of these external expressions in a stranger, more than in a bosom-companion[35]. Further, had we no other means but experience for understanding the external signs of passion, we could not expect any uniformity or any degree of skill in the bulk of individuals. But matters are ordered so differently, that the external expressions of passion form a language understood by all, by the young as well as the old, by the ignorant as well as the learned. I talk of the plain and legible characters of this language; for undoubtedly we are much indebted to experience in deciphering the dark and more delicate expressions. Where then shall we apply for a solution of this intricate problem, which seems to penetrate deep into human nature? In my mind it will be convenient to suspend the inquiry, till we be better acquainted with the nature of external signs and with their operations. These articles therefore shall be premised. The external signs of passion are of two kinds, voluntary and involuntary. The voluntary signs are also of two kinds: some are arbitrary and some natural. Words are arbitrary signs, excepting a few simple sounds expressive of certain internal emotions; and these sounds, being the same in all languages, must be the work of nature. But though words are arbitrary, the manner of employing them is not altogether so; for each passion has by nature peculiar expressions and tones suited to it. Thus the unpremeditated tones of admiration, are the same in all men; as also of compassion, resentment, and despair. Dramatic writers ought to be well acquainted with this natural manner of expressing passion. The chief talent of a fine writer, is a ready command of the expressions that nature dictates to every man when any vivid emotion struggles for utterance; and the chief talent of a fine reader, is a ready command of the tones suited to these expressions.
