Just as the propositions, “It is day,” and “It is night,” are full of meaning when separated, but meaningless if united; so also, granted that for you to take the larger share at a dinner is good for your body, still, it is bad for the maintenance of the proper kind of social feeling. When, therefore, you are eating with another person, remember to regard, not merely the value for your body of what lies before you, but also to maintain your respect for your host.
