Frances Kamm's "Principle of Permissible Harm" is an effort to derive a deontological constraint which coheres with our considered case judgments while also relying heavily on Kant's Categorical Imperative. The Principle states that one may harm in order to save more if and only if the harm is an effect or an aspect of the greater good itself. This principle is meant to address what Kamm feels are most people's considered case judgements, many of which involve deontological intuitions. For instance, Kamm argues that we believe it would be impermissible to kill one person to harvest his organs in order to save the lives of five others. Yet, we think it is morally permissible to divert a runaway trolley

 that would otherwise kill five innocent and immobile people onto a side track where one innocent and immobile person will be killed. Kamm believes the Principle of Permissible Harm explains the moral difference between these and other cases, and more importantly expresses a constraint telling us exactly when we may not act to bring about good ends—such as in the organ harvesting case.

In 2007, Kamm published a book that presents new theory that incorporates aspects of her "Principle of Permissible Harm", the "Doctrine of Productive Purity". Like the "Principle of Permissible Harm", the "Doctrine of Productive Purity" is an attempt to provide a deontological prescription for determining the circumstances in which people are permitted to act in a way that harms others.

The Divine Command Theory

Although not all Deontologists are religious, some believe in The 'Divine Command Theory'. 'The Divine Command Theory' is a cluster of related theories that state that an action is right if God has decreed that it is right. William of Ockham

, as they all held that moral obligations arise from God's commands. The Divine Command Theory is a form of deontology because, according to it, the rightness of any action depends upon that action being performed because it is a duty, not because of any good consequences arising from that action. If God commands people not to work on Sabbath

, then people act rightly if they do not work on Sabbath because God has commanded that they do not do so. If they do not work on Sabbath because they are lazy, then their action is not truly speaking "right", even though the actual physical action performed is the same. If God commands not to covet a neighbour's goods, this theory holds that it would be immoral to do so, even if coveting provides the beneficial outcome of a drive to succeed or do well.

Kantianism


Immanuel Kant

's theory of ethics is considered deontological for several different reasons. First, Kant argues that to act in the morally right way, people must act from duty (deon). Second, Kant argued that it was not the consequences of actions that make them right or wrong but the motives of the person who carries out the action.

Kant's argument that to act in the morally right way, one must act from duty, begins with an argument that the highest good must be both good in itself, and good without qualification. Something is "good in itself" when it is intrinsically good

, fail to be either intrinsically good or good without qualification. Pleasure, for example, appears to not be good without qualification, because when people take pleasure in watching someone suffering, this seems to make the situation ethically worse. He concludes that there is only one thing that is truly good:
Kant then argues that the consequences of an act of willing cannot be used to determine that the person has a good will; good consequences could arise by accident from an action that was motivated by a desire to cause harm to an innocent person, and bad consequences could arise from an action that was well-motivated. Instead, he claims, a person has a good will when he 'acts out of respect for the moral law'. People 'act out of respect for the moral law' when they act in some way because they have a duty to do so. So, the only thing that is truly good in itself is a good will, and a good will is only good when the willer chooses to do something because it is that person's duty. Thus, according to Kant, goodness depends on rightness.

Moral absolutism

Some deontologists are moral absolutists

, for example, argued that the only absolutely good thing is a good will, and so the single determining factor of whether an action is morally right is the will, or motive of the person doing it. If they are acting on a bad maxim, e.g. "I will lie", then their action is wrong, even if some good consequences come of it. Non-absolutist deontologists, such as W. D. Ross

Non-Aggression Principle

The non-aggression principle, also known as the non-aggression axiom and zero aggression principle, is an ethical stance which states that any initiation of force is illicit and contrary to natural law. It is the basic moral axiom of deontological libertarianism, most upheld by philosophers such as Robert Nozick

 argues that under deontology, individuals are bound by constraints (such as the requirement not to murder), but are also given options (such as the right not to give money to charity, if they do not wish to). His line of attack on deontology is to first show that constraints are invariably immoral, and then to show that options are immoral without constraints.
