WHETHER we ought to believe, or to disbelieve, what is said; or whether, if we do believe, we ought to be moved by it or not; what is it that tells us? Is it not the faculty of choice? Again, the very faculty of elocution, and that which ornaments discourse, if there be any such peculiar faculty, what doth it more than merely ornament and arrange expressions, as curlers do the hair? But whether it be better to speak or to be silent; or better to speak in this or in that manner; whether this be decent or indecent; and the season and use of each; what is it that tells us, but the faculty of choice?
