Kant claimed that autonomy—the ability to decide for oneself the moral laws one will follow—is the heart of ethics.
To let something or someone else decide what moral laws one will follow is “heteronomy” and is wrong because morality should depend on one’s own will—one’s own decision-making ability.
The will is a person’s ability to make decisions on the basis of reasons; Kant argues that nothing is good without qualification except a good will; and a good will is one that chooses what is morally right because it is right and not because it is pleasurable or in one’s self-interest.
Kant next argued the following:
Kant’s categorical imperative—the basic principle of morality—is the conclusion (3) of the preceding argument
in other words, it is morally wrong for me to do something unless it is something that I am willing to have everyone do and so something I believe everyone could do.
Kant argues that committing suicide, making false promises, failing to develop one’s talents, and failing
to help those in need are all morally wrong because they are all actions that I would not be willing
to have everyone do or actions that not everyone could do.
Kant gives a second version of the categorical imperative:
Critics say Kant’s theory cannot deal with conflicts among duties
Using Kant’s theory, Mappes argues that it is wrong to sexually use a person through coercion or deception, which is why rape and sexual harassment of employees are wrong.
Critics say that Kant’s theory implies that any kind of sexual activity between informed and consenting persons is morally right, and this seems too permissive
In passive euthanasia, a person is allowed to die from a disease without treatment that could prolong her life; in active euthanasia, something is done or given to the person that causes her death.
Gay-Williams uses natural law ethics to argue that because we have a natural inclination toward life and because our dignity comes from seeking that toward which we have a natural inclination, it is wrong
to destroy life through euthanasia.
Rachels uses utilitarianism to argue that when euthanasia benefits everyone concerned by putting an end to a person’s pain and suffering and violates no one’s rights, it is morally justified.
Rachels also uses Kantian ethics to argue that because we would not be willing to live by a rule that forced us to suffer pain when we had a terminal illness instead of being put painlessly to death, it is wrong to apply such a rule to others.
Each theory sheds a different light on considerations to keep in mind when deciding whether euthanasia is morally justified.
