Normative ethics involves arriving at moral standards that regulate right and wrong conduct. In a sense, it is a search for an ideal litmus test of proper behavior. The Golden Rule is a classic example of a normative principle: We should do to others what we would want others to do to us. Since I do not want my neighbor to steal my car, then it is wrong for me to steal her car. Since I would want people to feed me if I was starving, then I should help feed starving people. Using this same reasoning, I can theoretically determine whether any possible action is right or wrong. So, based on the Golden Rule, it would also be wrong for me to lie to, harass, victimize, assault, or kill others. The Golden Rule is an example of a normative theory that establishes a single principle against which we judge all actions. Other normative theories focus on a set of foundational principles, or a set of good character traits.
The key assumption in normative ethics is that there is only one ultimate criterion of moral conduct, whether it is a single rule or a set of principles. Three strategies will be noted here: (1) virtue theories, (2) duty theories, and (3) consequentialist theories.
a. Virtue Theories
Many philosophers believe that morality consists of following precisely defined rules of conduct, such as “don’t kill,” or “don’t steal.” Presumably, I must learn these rules, and then make sure each of my actions live up to the rules. Virtue ethics, however, places less emphasis on learning rules, and instead stresses the importance of developing good habits of character, such as benevolence (see moral character). Once I’ve acquired benevolence, for example, I will then habitually act in a benevolent manner. Historically, virtue theory is one of the oldest normative traditions in Western philosophy, having its roots in ancient Greek civilization. Plato emphasized four virtues in particular, which were later called cardinal virtues: wisdom, courage, temperance and justice. Other important virtues are fortitude, generosity, self-respect, good temper, and sincerity. In addition to advocating good habits of character, virtue theorists hold that we should avoid acquiring bad character traits, or vices, such as cowardice, insensibility, injustice, and vanity. Virtue theory emphasizes moral education since virtuous character traits are developed in one’s youth. Adults, therefore, are responsible for instilling virtues in the young.
Aristotle argued that virtues are good habits that we acquire, which regulate our emotions. For example, in response to my natural feelings of fear, I should develop the virtue of courage which allows me to be firm when facing danger. Analyzing 11 specific virtues, Aristotle argued that most virtues fall at a mean between more extreme character traits. With courage, for example, if I do not have enough courage, I develop the disposition of cowardice, which is a vice. If I have too much courage I develop the disposition of rashness which is also a vice. According to Aristotle, it is not an easy task to find the perfect mean between extreme character traits. In fact, we need assistance from our reason to do this. After Aristotle, medieval theologians supplemented Greek lists of virtues with three Christian ones, ortheological virtues: faith, hope, and charity. Interest in virtue theory continued through the middle ages and declined in the 19th century with the rise of alternative moral theories below. In the mid 20thcentury virtue theory received special attention from philosophers who believed that more recent ethical theories were misguided for focusing too heavily on rules and actions, rather than on virtuous character traits. Alasdaire MacIntyre (1984) defended the central role of virtues in moral theory and argued that virtues are grounded in and emerge from within social traditions.
b. Duty Theories
Many of us feel that there are clear obligations we have as human beings, such as to care for our children, and to not commit murder. Duty theories base morality on specific, foundational principles of obligation. These theories are sometimes called deontological, from the Greek word deon, or duty, in view of the foundational nature of our duty or obligation. They are also sometimes called nonconsequentialist since these principles are obligatory, irrespective of the consequences that might follow from our actions. For example, it is wrong to not care for our children even if it results in some great benefit, such as financial savings. There are four central duty theories.
The first is that championed by 17th century German philosopher Samuel Pufendorf, who classified dozens of duties under three headings: duties to God, duties to oneself, and duties to others. Concerning our duties towards God, he argued that there are two kinds:
a theoretical duty to know the existence and nature of God, and
a practical duty to both inwardly and outwardly worship God.
Concerning our duties towards oneself, these are also of two sorts:
duties of the soul, which involve developing one’s skills and talents, and
duties of the body, which involve not harming our bodies, as we might through gluttony or drunkenness, and not killing oneself.
Concerning our duties towards others, Pufendorf divides these between absolute duties, which are universally binding on people, and conditional duties, which are the result of contracts between people. Absolute duties are of three sorts:
avoid wronging others,
treat people as equals, and
promote the good of others.
Conditional duties involve various types of agreements, the principal one of which is the duty is to keep one’s promises.
A second duty-based approach to ethics is rights theory. Most generally, a “right” is a justified claim against another person’s behavior – such as my right to not be harmed by you (see also human rights). Rights and duties are related in such a way that the rights of one person implies the duties of another person. For example, if I have a right to payment of $10 by Smith, then Smith has a duty to pay me $10. This is called the correlativity of rights and duties. The most influential early account of rights theory is that of 17th century British philosopher John Locke, who argued that the laws of nature mandate that we should not harm anyone’s life, health, liberty or possessions. For Locke, these are our natural rights, given to us by God. Following Locke, the United States Declaration of Independence authored by Thomas Jefferson recognizes three foundational rights: life, liberty, and the pursuit of happiness. Jefferson and others rights theorists maintained that we deduce other more specific rights from these, including the rights of property, movement, speech, and religious expression. There are four features traditionally associated with moral rights. First, rights are natural insofar as they are not invented or created by governments. Second, they are universal insofar as they do not change from country to country. Third, they are equal in the sense that rights are the same for all people, irrespective of gender, race, or handicap. Fourth, they are inalienable which means that I cannot hand over my rights to another person, such as by selling myself into slavery.
A third duty-based theory is that by Kant, which emphasizes a single principle of duty. Influenced by Pufendorf, Kant agreed that we have moral duties to oneself and others, such as developing one’s talents, and keeping our promises to others. However, Kant argued that there is a more foundational principle of duty that encompasses our particular duties. It is a single, self-evident principle of reason that he calls the “categorical imperative.” A categorical imperative, he argued, is fundamentally different from hypothetical imperatives that hinge on some personal desire that we have, for example, “If you want to get a good job, then you ought to go to college.” By contrast, a categorical imperative simply mandates an action, irrespective of one’s personal desires, such as “You ought to do X.” Kant gives at least four versions of the categorical imperative, but one is especially direct: Treat people as an end, and never as a means to an end. That is, we should always treat people with dignity, and never use them as mere instruments. For Kant, we treat people as an end whenever our actions toward someone reflect the inherent value of that person. Donating to charity, for example, is morally correct since this acknowledges the inherent value of the recipient. By contrast, we treat someone as a means to an end whenever we treat that person as a tool to achieve something else. It is wrong, for example, to steal my neighbor’s car since I would be treating her as a means to my own happiness. The categorical imperative also regulates the morality of actions that affect us individually. Suicide, for example, would be wrong since I would be treating my life as a means to the alleviation of my misery. Kant believes that the morality of all actions can be determined by appealing to this single principle of duty.
A fourth and more recent duty-based theory is that by British philosopher W.D. Ross, which emphasizesprima facie duties. Like his 17th and 18th century counterparts, Ross argues that our duties are “part of the fundamental nature of the universe.” However, Ross’s list of duties is much shorter, which he believes reflects our actual moral convictions:
Fidelity: the duty to keep promises
Reparation: the duty to compensate others when we harm them
Gratitude: the duty to thank those who help us
Justice: the duty to recognize merit
Beneficence: the duty to improve the conditions of others
Self-improvement: the duty to improve our virtue and intelligence
Nonmaleficence: the duty to not injure others
Ross recognizes that situations will arise when we must choose between two conflicting duties. In a classic example, suppose I borrow my neighbor’s gun and promise to return it when he asks for it. One day, in a fit of rage, my neighbor pounds on my door and asks for the gun so that he can take vengeance on someone. On the one hand, the duty of fidelity obligates me to return the gun; on the other hand, the duty of nonmaleficence obligates me to avoid injuring others and thus not return the gun. According to Ross, I will intuitively know which of these duties is my actual duty, and which is my apparent or prima facieduty. In this case, my duty of nonmaleficence emerges as my actual duty and I should not return the gun.
c. Consequentialist Theories
It is common for us to determine our moral responsibility by weighing the consequences of our actions. According to consequentialism, correct moral conduct is determined solely by a cost-benefit analysis of an action’s consequences:
Consequentialism: An action is morally right if the consequences of that action are more favorable than unfavorable.
Consequentialist normative principles require that we first tally both the good and bad consequences of an action. Second, we then determine whether the total good consequences outweigh the total bad consequences. If the good consequences are greater, then the action is morally proper. If the bad consequences are greater, then the action is morally improper. Consequentialist theories are sometimes called teleological theories, from the Greek word telos, or end, since the end result of the action is the sole determining factor of its morality.
Consequentialist theories became popular in the 18th century by philosophers who wanted a quick way to morally assess an action by appealing to experience, rather than by appealing to gut intuitions or long lists of questionable duties. In fact, the most attractive feature of consequentialism is that it appeals to publicly observable consequences of actions. Most versions of consequentialism are more precisely formulated than the general principle above. In particular, competing consequentialist theories specify which consequences for affected groups of people are relevant. Three subdivisions of consequentialism emerge:
Ethical Egoism: an action is morally right if the consequences of that action are more favorable than unfavorable only to the agent performing the action.
Ethical Altruism: an action is morally right if the consequences of that action are more favorable than unfavorable to everyone except the agent.
Utilitarianism: an action is morally right if the consequences of that action are more favorable than unfavorable to everyone.
All three of these theories focus on the consequences of actions for different groups of people. But, like all normative theories, the above three theories are rivals of each other. They also yield different conclusions. Consider the following example. A woman was traveling through a developing country when she witnessed a car in front of her run off the road and roll over several times. She asked the hired driver to pull over to assist, but, to her surprise, the driver accelerated nervously past the scene. A few miles down the road the driver explained that in his country if someone assists an accident victim, then the police often hold the assisting person responsible for the accident itself. If the victim dies, then the assisting person could be held responsible for the death. The driver continued explaining that road accident victims are therefore usually left unattended and often die from exposure to the country’s harsh desert conditions. On the principle of ethical egoism, the woman in this illustration would only be concerned with the consequences of her attempted assistance as she would be affected. Clearly, the decision to drive on would be the morally proper choice. On the principle of ethical altruism, she would be concerned only with the consequences of her action as others are affected, particularly the accident victim. Tallying only those consequences reveals that assisting the victim would be the morally correct choice, irrespective of the negative consequences that result for her. On the principle of utilitarianism, she must consider the consequences for both herself and the victim. The outcome here is less clear, and the woman would need to precisely calculate the overall benefit versus disbenefit of her action.
i. Types of Utilitarianism
Jeremy Bentham presented one of the earliest fully developed systems of utilitarianism. Two features of his theory are noteworty. First, Bentham proposed that we tally the consequences of each action we perform and thereby determine on a case by case basis whether an action is morally right or wrong. This aspect of Bentham’s theory is known as act-utilitiarianism. Second, Bentham also proposed that we tally the pleasure and pain which results from our actions. For Bentham, pleasure and pain are the only consequences that matter in determining whether our conduct is moral. This aspect of Bentham’s theory is known as hedonistic utilitarianism. Critics point out limitations in both of these aspects.
First, according to act-utilitarianism, it would be morally wrong to waste time on leisure activities such as watching television, since our time could be spent in ways that produced a greater social benefit, such as charity work. But prohibiting leisure activities doesn’t seem reasonable. More significantly, according to act-utilitarianism, specific acts of torture or slavery would be morally permissible if the social benefit of these actions outweighed the disbenefit. A revised version of utilitarianism called rule-utilitarianismaddresses these problems. According to rule-utilitarianism, a behavioral code or rule is morally right if the consequences of adopting that rule are more favorable than unfavorable to everyone. Unlike act utilitarianism, which weighs the consequences of each particular action, rule-utilitarianism offers a litmus test only for the morality of moral rules, such as “stealing is wrong.” Adopting a rule against theft clearly has more favorable consequences than unfavorable consequences for everyone. The same is true for moral rules against lying or murdering. Rule-utilitarianism, then, offers a three-tiered method for judging conduct. A particular action, such as stealing my neighbor’s car, is judged wrong since it violates a moral rule against theft. In turn, the rule against theft is morally binding because adopting this rule produces favorable consequences for everyone. John Stuart Mill’s version of utilitarianism is rule-oriented.
Second, according to hedonistic utilitarianism, pleasurable consequences are the only factors that matter, morally speaking. This, though, seems too restrictive since it ignores other morally significant consequences that are not necessarily pleasing or painful. For example, acts which foster loyalty and friendship are valued, yet they are not always pleasing. In response to this problem, G.E. Moore proposedideal utilitarianism, which involves tallying any consequence that we intuitively recognize as good or bad (and not simply as pleasurable or painful). Also, R.M. Hare proposed preference utilitarianism, which involves tallying any consequence that fulfills our preferences.
ii. Ethical Egoism and Social Contract Theory
We have seen (in Section 1.b.i) that Hobbes was an advocate of the methaethical theory of psychological egoism—the view that all of our actions are selfishly motivated. Upon that foundation, Hobbes developed a normative theory known as social contract theory, which is a type of rule-ethical-egoism. According to Hobbes, for purely selfish reasons, the agent is better off living in a world with moral rules than one without moral rules. For without moral rules, we are subject to the whims of other people’s selfish interests. Our property, our families, and even our lives are at continual risk. Selfishness alone will therefore motivate each agent to adopt a basic set of rules which will allow for a civilized community. Not surprisingly, these rules would include prohibitions against lying, stealing and killing. However, these rules will ensure safety for each agent only if the rules are enforced. As selfish creatures, each of us would plunder our neighbors’ property once their guards were down. Each agent would then be at risk from his neighbor. Therefore, for selfish reasons alone, we devise a means of enforcing these rules: we create a policing agency which punishes us if we violate these rules.
