Yet some there are who can assign a speaker his part, and think no duty incumbent on themselves all the while; who will have him prepare and premeditate what he has to deliver, and yet throw themselves into an auditory without any preparation or consideration, as if they were invited to a feast, to revel and take their pleasures at another’s cost. Yet it is known that even a guest has some things required of him to make him suitable and agreeable, and certainly a hearer has much more; because he ought to be a sharer in the discourse and an assistant to the speaker. Neither will it become him to be severe at all turns upon every slight miscarriage or perpetually putting the speaker’s elocution and action to the test, while he himself is guilty of grosser enormities in hearing, without danger or control. But as at tennis he that takes the ball turns and winds his body according to the motion of the server, so a kind of proportion is to be observed between the speaker and the hearer, if both will discharge their several duties.
