As the proposition, either it is day, or it is night , has much force in a disjunctive argument, but none at all in a conjunctive one; so, at a feast, to choose the largest share is very suitable to the bodily appetite, but utterly inconsistent with the social spirit of the entertainment. Remember, then, when you eat with another, not only the value to the body of those things which are set before you, but also the value of proper courtesy towards your host. If you have assumed any character beyond your strength, you have both demeaned yourself ill in that, and quitted one which you might have supported. As in walking you take care not to tread upon a nail, or turn your foot, so likewise take care not to hurt the ruling faculty of your mind. And if we were to guard against this in every action, we should enter upon action more safely.
