Deontological Ethics comes from the Greek word deon, meaning "duty."
This is a non-consequentialist theory. It stands in direct opposition to Utilitarianism.
Core Principle: The morality of an action is based on the nature of the action itself (whether it follows a rule or "duty"), not on its consequences.
Immanuel Kant (1724-1804) begins his ethics by looking for something that is unconditionally good.
He rejects happiness, intelligence, and courage as unconditionally good, because they can all be used for evil purposes (e.g., a happy, intelligent, courageous bank robber).
Kant's Famous Opening: "Nothing in the world—indeed nothing even beyond the world—can possibly be conceived which could be called good without qualification except a good will."
If the Good Will is the *motive*, what is the *rule* it follows? Kant says the Good Will follows the Categorical Imperative. This is the supreme principle of morality.
Kant gives several formulations. The two most famous are:
"Act only according to that maxim whereby you can, at the same time, will that it should become a universal law."
"Act in such a way that you treat humanity, whether in your own person or in the person of any other, never merely as a means, but always at the same time as an end."
This concept ties back to the Good Will. For an action to have moral worth, it must be done from duty, not just in accordance with duty.
Kant gives the example of a shopkeeper who is honest with his customers.
| Motive | Kant's Judgement |
|---|---|
| He is honest because he fears getting caught (bad reputation, legal trouble). | No Moral Worth. This is action in accordance with duty, but done from self-interest. |
| He is honest because he is naturally sympathetic and likes his customers. | No Moral Worth. This is also in accordance with duty, but done from inclination (emotion), not reason. |
| He is honest because he is a cold-hearted person who hates his customers, but he knows that honesty is the right thing to do. | This has Moral Worth. The action is done from duty, for duty's sake alone. |
W. D. Ross (1877-1971) was a deontologist who felt Kant was too absolute. Kant's theory allows for *no exceptions* (e.g., you can't lie even to save a life). Ross found this problematic.
Ross argues that there is not just *one* supreme moral principle (like the Categorical Imperative), but a *plurality* (many) of them. He calls these Prima Facie Duties.
Prima Facie Duty: An "at first glance" duty. It is a moral obligation that is binding, *unless* it conflicts with a stronger moral obligation in a particular situation.
Ross's (non-exhaustive) list of Prima Facie Duties:
For Ross, moral dilemmas happen when these Prima Facie duties conflict.
Example: The classic "Inquiring Murderer." A murderer asks you where your friend is.
In this case, Ross says we must use our moral intuition to determine our Actual Duty. It is "self-evident" that the duty of Non-maleficence is stronger, and therefore our *actual* duty in this situation is to lie.
