As the proposition, it is either day, or it is night, is of great importance for the disjunctive argument, but for the conjunctive, is of no value, so in a symposium (entertainment) to select the larger share is of great value for the body, but for the maintenance of the social feeling is worth nothing. When, then, you are eating with another, remember, to look not only to the value for the body of the things set before you, but also to the value of the behavior towards the host which ought to be observed.
