There are others who think that the speaker has a function to perform, and the hearer none. They think it only right that the speaker shall come with his discourse carefully thought out and prepared, while they, without consideration or thought of their obligations, rush in and take their seats exactly as though they had come to dinner, to have a good time while others toil. And yet even a well-bred guest at dinner has a function to perform, much more a hearer; for he is a participant in the discourse and a fellow-worker with the speaker, and he ought not rigorously to examine the speaker’s little slips, applying his criticism to every word and action, while he himself, without being subject to any criticism, acts unhandsomely and commits many gross improprieties in the matter of listening. On the contrary, just as in playing ball it is necessary for the catcher to adapt his movements to those of the thrower and to be actively in accord with him, so with discourses, there is a certain accord between the speaker and the hearer, if each is heedful of his obligation.
