=18. General principles of social duties: to do good, not to do evil.=--All human actions, in regard to others, may be reduced to these two precepts: 1, to do good to men; 2, not to do them harm. To this all the virtues of social morality may be reduced. But before exhibiting these virtues and vices more in detail, let us explain what is understood by the expressions _to do good_ and _to do evil_. In the most general and apparent sense to do any one good would seem to be _to give him pleasure_; to do him harm, would seem to be _to give him pain_. Yet, is it always doing good to a person to procure him pleasure? and is it always doing him harm, to cause him pain? For example, Kant[6] says, "Shall we allow the idler soft cushions; the drunkard wines in abundance; the rogue an agreeable face and manners, to deceive more easily; the violent man audacity and a good fist?" Would it really be doing good to these men to grant them the object of their desires, what may satisfy their passions? On the other hand, the surgeon who amputates a mortified limb, the dentist who pulls out a bad tooth, the teacher who obliges you to learn, the father who corrects your faults or restrains your passions, do they really do you harm because they give you pain? No, certainly not. There are, then, cases where to do some one good is to cause him pain, and to do him harm is to procure him pleasure. One may reasonably reduce all principles of social morality to these two maxims of the gospel: "Do not do to others what you do not wish them do to you;"--"Do to others as you wish to be done by." These two maxims are admirable, certainly; but they must be interpreted rightly. If, for instance, we have done wrong, do we generally wish to be corrected and punished? When we are yielding to a passion, do we wish to be repressed in it, have it repelled? On the contrary, do we not rather wish to be allowed to enjoy it, and have the free range of our vices? Is not this generally what we all wish, when the voice of duty is mute and does not silence our passionate feelings? If this is so, should we wish to do to others as we wish in similar circumstances, namely, in the gratification of passions, to be done by? Should we not rather do to them what we should not like them do to us, that is, punish and correct them? It is evidently not in that sense we are to understand the two evangelical maxims; for they would be then no other than maxims of remissness and improper kindness; whilst they, on the contrary, express most admirably a moral truth; only when they speak of what we wish, they mean a _true_ and _good_ wish, not the desires of passion; the same when we recommend men to do good, we mean real good and not apparent good; as also in recommending to do no harm, we mean real harm, not the illusory harm of the senses, imagination and passions.
