Do Your Duty: Kant

Acting from Duty

We have then to develop the notion of a will which deserves to be highly esteemed for itself and is good without a view to anything further, a notion which exists already in the sound natural understanding, requiring rather to be cleared up than to be taught, and which in estimating the value of our actions always takes the first place and constitutes the condition of all the rest. In order to do this, we will take the notion of duty, which includes that of a good will, although implying certain subjective restrictions and hindrances. These, however, far from concealing it, or rendering it unrecognizable, rather bring it out by contrast and make it shine forth so much the brighter.

I omit here all actions which are already recognized as inconsistent with duty, although they may be useful for this or that purpose, for with these the question whether they are done from duty cannot arise at all, since they even conflict with it. I also set aside those actions which really conform to duty, but to which men have no direct inclination, performing them because they are impelled thereto by some other inclination. For in this case we can readily distinguish whether the action which agrees with duty is done from duty, or from a selfish view. It is much harder to make this distinction when the action accords with duty and the subject has besides a direct inclination to it.

Example 1: The Honest Grocer

Kant continues by offering examples of good motivations.  You cannot be motivated purely by self-interest to do what is morally right:

It is always a matter of duty that a dealer should not over charge an inexperienced purchaser; and wherever there is much commerce the prudent tradesman does not overcharge, but keeps a fixed price for everyone, so that a child buys of him as well as any other. Men are thus honestly served; but this is not enough to make us believe that the tradesman has so acted from duty and from principles of honesty: his own advantage required it; it is out of the question in this case to suppose that he might besides have a direct inclination in favor of the buyers, so that, as it were, from love he should give no advantage to one over another.

Example 2: The Sad Philanthropist

And -- Kant argues -- you can do what is morally right even if you don't get satisfaction from it:

To be beneficent when we can is a duty; and besides this, there are many minds so sympathetically constituted that, without any other motive of vanity or self-interest, they find a pleasure in spreading joy around them and can take delight in the satisfaction of others so far as it is their own work. But I maintain that in such a case an action of this kind, however proper, however amiable it may be, has nevertheless no true moral worth, but is on a level with other inclinations, e. g., the inclination to honor, which, if it is happily directed to that which is in fact of public utility and accordant with duty and consequently honorable, deserves praise and encouragement, but not esteem.

For the maxim lacks the moral import, namely, that such actions be done from duty, not from inclination. Put the case that the mind of that philanthropist were clouded by sorrow of his own, extinguishing all sympathy with the lot of others, and that, while he still has the power to benefit others in distress, he is not touched by their trouble because he is absorbed with his own; and now suppose that he tears himself out of this dead insensibility, and performs the action without any inclination to it, but simply from duty, then first has his action its genuine moral worth. Further still; if nature has put little sympathy in the heart of this or that man; if he, supposed to be an upright man, is by temperament cold and indifferent to the sufferings of others, perhaps because in respect of his own he is provided with the special gift of patience and fortitude and supposes, or even requires, that others should have the same- and such a man would certainly not be the meanest product of nature- but if nature had not specially framed him for a philanthropist, would he not still find in himself a source from whence to give himself a far higher worth than that of a good-natured temperament could be? Unquestionably. It is just in this that the moral worth of the character is brought out which is incomparably the highest of all, namely, that he is beneficent, not from inclination, but from duty.

Acting from Inclination vs From Duty

Here is a key distinction we need to understand Kant's discussion of these examples.

Some actions are done purely from inclination (desire).  For example, eating ice cream is something we do purely for the pleasure of it.  

Some actions are done purely from duty. For example, a soldier who jumps on a grenade to save the life of a civilian is getting no pleasure from his sacrifice but does it instead because she believes she is obligated to make the sacrifice or because she respects the moral value that her sacrifice represents.

Many actions are done from a mixture of inclination and duty.  For example, you might volunteer with a children's charity both because you have a sense of duty and because the children are cute and make you laugh.  

For Kant, when you have mixed motives, you only get moral credit or blame for the motivations that come from duty.

What is a Maxim?

An imperative is a command. A maxim combings such a command with some reason for acting, and the result is a description of an action that we can recognize as intentional. 

For instance: "Always wear sunscreen at the beach in order to avoid sunburn."

Or: "Never cheat in order to get ahead."

For Kant, every intentional action has a corresponding maxim, a description that combines a command to act with the reason for which you are acting.

Universalizing Your Maxim

The key to obeying the categorical imperative, then, is to make sure that your maxim is such that you could consistently will that it become a universal law. What does this mean?

A maxim would be a universal law if any agent who found herself in circumstances relevantly similar to the circumstances in which you now find yourself obeyed the maxim that you are now acting on.

The crucial question is, could this hypothetical world in which your maxim is a universal law exist without creating a contradiction or a conflict with another universal law of nature.

Example: False Promises

Kant thinks one categorical imperative is to not manipulate other rational agents by making false/lying promises to them:

The common reason of men in its practical judgments perfectly coincides with this and always has in view the principle here suggested. Let the question be, for example: May I when in distress make a promise with the intention not to keep it? I readily distinguish here between the two significations which the question may have: Whether it is prudent, or whether it is right, to make a false promise?

The shortest way, however, and an unerring one, to discover the answer to this question whether a lying promise is consistent with duty, is to ask myself, “Should I be content that my maxim (to extricate myself from difficulty by a false promise) should hold good as a universal law, for myself as well as for others? and should I be able to say to myself, “Every one may make a deceitful promise when he finds himself in a difficulty from which he cannot otherwise extricate himself?” Then I presently become aware that while I can will the lie, I can by no means will that lying should be a universal law. For with such a law there would be no promises at all, since it would be in vain to allege my intention in regard to my future actions to those who would not believe this allegation, or if they over hastily did so would pay me back in my own coin. Hence my maxim, as soon as it should be made a universal law, would necessarily destroy itself. I do not, therefore, need any far-reaching penetration to discern what I have to do in order that my will may be morally good. Inexperienced in the course of the world, incapable of being prepared for all its contingencies, I only ask myself: Canst thou also will that thy maxim should be a universal law? If not, then it must be rejected, and that not because of a disadvantage accruing from it to myself or even to others, but because it cannot enter as a principle into a possible universal legislation, and reason extorts from me immediate respect for such legislation.

A Video Example: Lying

Suicide

Kant gives other examples of moral decisions which involve the categorical imperative:

A man reduced to despair by a series of misfortunes feels wearied of life, but is still so far in possession of his reason that he can ask himself whether it would not be contrary to his duty to himself to take his own life. Now he inquires whether the maxim of his action could become a universal law of nature. His maxim is: “From self-love I adopt it as a principle to shorten my life when its longer duration is likely to bring more evil than satisfaction.” It is asked then simply whether this principle founded on self-love can become a universal law of nature.

Now we see at once that a system of nature of which it should be a law to destroy life by means of the very feeling whose special nature it is to impel to the improvement of life would contradict itself and, therefore, could not exist as a system of nature; hence that maxim cannot possibly exist as a universal law of nature and, consequently, would be wholly inconsistent with the supreme principle of all duty.

Dishonest Borrower

Another finds himself forced by necessity to borrow money. He knows that he will not be able to repay it, but sees also that nothing will be lent to him unless he promises stoutly to repay it in a definite time. He desires to make this promise, but he has still so much conscience as to ask himself: “Is it not unlawful and inconsistent with duty to get out of a difficulty in this way?” Suppose however that he resolves to do so: then the maxim of his action would be expressed thus: “When I think myself in want of money, I will borrow money and promise to repay it, although I know that I never can do so.”

Now this principle of self-love or of one’s own advantage may perhaps be consistent with my whole future welfare; but the question now is, “Is it right?” I change then the suggestion of self-love into a universal law, and state the question thus: “How would it be if my maxim were a universal law?” Then I see at once that it could never hold as a universal law of nature, but would necessarily contradict itself. For supposing it to be a universal law that everyone when he thinks himself in a difficulty should be able to promise whatever he pleases, with the purpose of not keeping his promise, the promise itself would become impossible, as well as the end that one might have in view in it, since no one would consider that anything was promised to him, but would ridicule all such statements as vain pretenses.

The Bitter Rich Man

A third, who is in prosperity, while he sees that others have to contend with great wretchedness and that he could help them, thinks: “What concern is it of mine? Let everyone be as happy as Heaven pleases, or as be can make himself; I will take nothing from him nor even envy him, only I do not wish to contribute anything to his welfare or to his assistance in distress!” Now no doubt if such a mode of thinking were a universal law, the human race might very well subsist and doubtless even better than in a state in which everyone talks of sympathy and good-will, or even takes care occasionally to put it into practice, but, on the other side, also cheats when he can, betrays the rights of men, or otherwise violates them.

But although it is possible that a universal law of nature might exist in accordance with that maxim, it is impossible to will that such a principle should have the universal validity of a law of nature. For a will which resolved this would contradict itself, inasmuch as many cases might occur in which one would have need of the love and sympathy of others, and in which, by such a law of nature, sprung from his own will, he would deprive himself of all hope of the aid he desires. These are a few of the many actual duties, or at least what we regard as such, which obviously fall into two classes on the one principle that we have laid down.

The Talented Recluse

A fourth finds in himself a talent which with the help of some culture might make him a useful man in many respects. But he finds himself in comfortable circumstances and prefers to indulge in pleasure rather than to take pains in enlarging and improving his happy natural capacities. He asks, however, whether his maxim of neglect of his natural gifts, besides agreeing with his inclination to indulgence, agrees also with what is called duty.

He sees then that a system of nature could indeed subsist with such a universal law although men (like the South Sea islanders) should let their talents rest and resolve to devote their lives merely to idleness, amusement, and propagation of their species- in a word, to enjoyment; but he cannot possibly will that this should be a universal law of nature, or be implanted in us as such by a natural instinct. For, as a rational being, he necessarily wills that his faculties be developed, since they serve him and have been given him, for all sorts of possible purposes.
