Introduction

You often face moments where customs, laws, and religious dogmas conflict, leaving you unsure how to act rightly. Moral philosophy steps in to help you examine these dilemmas through critical reasoning and human experience rather than blind obedience.

Louis P. Pojman explains how ethical theory moves beyond mere personal preference to construct objective, action-guiding principles. You will explore the foundational questions of moral life as you journey through egoism, utilitarianism, deontology, and virtue ethics.

• What makes an action right or wrong?
• Does morality depend on religion or human reason?
• How do you balance self-interest with the welfare of others?
• Are moral truths universal or relative to culture?

1. The Nature of Moral Philosophy

Moral philosophy seeks valid principles grounded in reason and human experience to govern how you ought to live. Unlike religion which relies on revelation and authority, or law and etiquette which have narrow scopes and external enforcement, this systematic endeavor evaluates concepts and actions. Moral philosophy is a systematic endeavor using human reason and experience to establish action-guiding principles and evaluate character.

Genral Introduction

Positive morality reflects the customs of a particular group. You might follow laws because you fear punishment or social shame. Law and custom often overlap with morality, yet they remain distinct. In 1351 King Edward III promulgated a law against treason making it a crime merely to think homicidal thoughts. Such legal standards fail to exhaust the demands of true moral reflection.

In Queens, New York, 39 people watched an assailant beat and kill Kitty Genovese for some forty-five minutes without intervening. Those onlookers broke no positive laws by staying inside their apartments. You recognize that their inaction remains profoundly culpable because ethics demands more than mere obedience to legal statutes.

Domains of Ethical Assessment

Ethical analysis generally falls into four distinct domains: action, consequences, character, and motive. Action-oriented theories evaluate acts as obligatory, wrong, or optional. Consequentialist theories focus on outcomes. Character theories focus on virtues as in Aristotle. Motive theories factor in the agent's intentions, allowing two identical acts with different intentions to be judged differently.

John pushing Joan off a ledge breaks her leg. If he does so out of anger to harm her it is wrong. If he does so to save her from a flying knife it is the right thing to do.

You must also consider how religion intersects with these domains. The divine command theory asserts that moral standards depend entirely on God's will. Under this view, right simply means willed by God. This creates problems such as making goodness a tautology and reducing morality to arbitrary commands where heinous acts could theoretically become good if commanded. William of Occam stated that actions like theft and adultery could become meritorious if performed under a divine command.

The autonomy thesis argues that ethics are independent and even God must obey the moral order. This approach posits that morality exists independently, much like logic and mathematics. You find that moral philosophy steps in to provide objective criteria when religious commands conflict or lack rational justification.

2. Egoism and the Social Contract

Ethical egoism and social contract theories attempt to ground morality in self-interest and the mutual desire for security.

You find that ethical egoism and social contract theories try to build morality from self-interest. They look at human drives rather than divine commands to explain why you should follow rules.

The State of Nature

In the unregulated state of nature without a common power, human life is characterized by a war of everyone against everyone, making life solitary, poor, nasty, brutish, and short. Because humans are roughly equal in physical and mental faculties, competition for scarce resources, fear of others leading to preemptive attacks, and the pursuit of glory cause constant conflict. Without a coercive power to maintain order, there is no industry, agriculture, commerce, or safety.

Hobbes points to savage peoples in parts of America and the behavior of people who lock their doors at night or lock their chests even when laws and public officers exist.

Prudence dictates natural laws that lead humans to seek peace through mutual contracts and the establishment of a sovereign coercive power. The fundamental law of nature is to seek peace and follow it, while the second law is to be willing to lay down the natural right to all things if others are willing as well, giving up absolute freedom for mutual security. Since words without swords are insufficient, a strong sovereign state is necessary to enforce covenants.

You follow these principles for survival:

• Seek peace and follow it.
• Be willing, when others are so too, to lay down this right to all things and be contented with so much liberty against other men as you would allow other men against yourself.
• Perform your covenants made.

A Critique of Ethical Egoism

Ayn Rand argued that ethical egoism is the only philosophy that respects the supreme value and integrity of individual human life. Rand viewed altruism as a destructive force that treats individuals as sacrificial animals whose sole purpose is to serve others. Rachels counters that Rand frames the alternative too extremely, ignoring the middle ground of commonsense morality which balances personal and collective interests.

Barbara Brandon responded to a student asking about the poor by stating that helpers will not be stopped.

The achievement of one's own happiness is man's highest moral purpose, and pride is the sum of all virtues. Happiness is the successful state of life resulting from the achievement of one's values. A morality of sacrifice forces people into the dual roles of victim and parasite, leaving them consumed by guilt and frustration. Treating oneself as an end in and of itself requires rejecting the demand for unearned self-immolation.

You must follow these rules to practice this view:

• Treat as the mark of a cannibal any man's demand for your help if he claims it as his right or as a moral duty.
• Accept that the achievement of your happiness is the only moral purpose of your life.
• Learn to value yourself and fight for your happiness.

Ethical egoism is unacceptably arbitrary in the same way racism is, because it grants special moral weight to oneself without pointing to any relevant justifying difference. Just as racism divides people by race without factual justification, ethical egoism arbitrarily divides humanity into oneself and all others, favoring the former. Because no individual possesses unique qualities that make them inherently superior or more deserving than anyone else, ethical egoism collapses as a rational moral theory.

3. Utilitarianism and Consequentialism

Utilitarianism evaluates actions based on their consequences and their tendency to maximize pleasure or psychological satisfaction.

Jeremy Bentham establishes the principle of utility, stating that nature governs mankind under two sovereign masters: pain and pleasure. The principle of utility approves or disapproves of every action according to its tendency to augment or diminish the happiness of the party whose interest is in question. Pain and pleasure determine what you ought to do and provide the foundation for legislation and morals.

Bentham provides a calculus to measure the value of a lot of pleasure or pain based on seven specific circumstances. For an individual, pleasures and pains are measured by intensity, duration, certainty or uncertainty, and propinquity or remoteness. When estimating the tendency of an act, fecundity and purity are added. To evaluate an act affecting a community, a seventh circumstance, extent, representing the number of persons affected, must be included.

You can apply this method step by step:

• Begin with any one person whose interests are immediately affected by the act.
• Take an account of the value of each distinguishable pleasure produced in the first instance.
• Take an account of the value of each pain produced in the first instance.
• Take an account of the value of each subsequent pleasure constituting fecundity and impurity.
• Take an account of the value of each subsequent pain.
• Sum up all values of pleasures on one side and pains on the other to find the individual balance.
• Take account of the number of persons whose interests are concerned and repeat the process for each individual.
• Sum up the degrees of good tendency and bad tendency separately, then take the general balance for the community.

John Stuart Mill distinguishes eudaimonistic utilitarianism from Bentham's hedonism by introducing qualitative differences in pleasures. Mill argues that pleasures derived from higher faculties are qualitatively superior and more valuable than mere bodily sensations. The test for quality is the preference given by competent judges who have experienced both types of pleasure.

Mill famously stated that it is better to be a human being dissatisfied than a pig satisfied, and better to be Socrates dissatisfied than a fool satisfied.

Rule-Utilitarianism and Its Critics

Rule-utilitarianism evaluates actions based on the consequences of adopting a general rule, whereas act-utilitarianism looks only at the consequences of the individual act.

Act-utilitarianism holds that the rightness of an act is determined solely by its total consequences in a specific instance, even if it involves breaking established rules in secret. Rule-utilitarianism contends that you must consider the consequences of universalizing the rule or practice, arguing that secret violations or exceptions undermine the entire system.

A professor is begged by a student to change a C grade to a B so the student can get into medical school, arguing that no one else will ever know and everyone will be happier. Act-utilitarianism struggles to forbid this if secrecy is maintained, whereas rule-utilitarianism condemns it because the general practice of altering grades for pity destroys the reliability of academic transcripts.

Rules can be made more specific to account for exceptions, but only when the subclass of acts produces empirically different consequences from the general rule. Adding arbitrary details like days of the week, hair color, or facial blemishes to a moral rule is irrelevant because it changes nothing about the act's consequences. Conversely, distinguishing between unprovoked violence and self-defense is relevant because the subclasses yield vastly different societal impacts.

You follow these actions when examining rules:

• Break down general classes of actions into more specific classes.
• Consider separately the effects of each subclass.
• Stop specifying when subclasses no longer produce genuinely different consequences.

A rule stating that you should not lie on Tuesdays is absurdly specific because lies told on Tuesdays have the same effects as lies told on any other day. However, a rule against killing except in self-defense is a relevantly specific subclass because killing an armed attacker prevents indiscriminate murder and preserves the innocent.

Utilitarianism can require you to take actions that violate your deepest moral convictions by demanding you choose the lesser of evils. George, an unemployed chemist in poor health with a struggling family, is offered a job in biological warfare research which he opposes, but utilitarian logic obligates him to take it to prevent a more unscrupulous scientist from doing greater harm.

4. Deontology and Kantian Ethics

Deontological ethics judges actions based on intrinsic features and duty rather than outcomes, anchored by Kant's Categorical Imperative.

Immanuel Kant lived from 1724 to 1804. He published The Critique of Pure Reason in 1781 and Grounding for the Metaphysics of Morals in 1785. Only a good will, acting purely out of a sense of duty rather than inclination or self-interest, possesses unqualified moral worth. Talents of the mind and gifts of fortune can become extremely bad and harmful without a good will to correct them. A good will is good not because of what it accomplishes or its fitness to attain some proposed end, but solely through its willing, shining like a jewel as something that has its full value in itself.

A prudent merchant does not overcharge an inexperienced child customer to maintain a fixed price, but this honest service lacks true moral worth because his own business advantage required it.

Kant's Categorical Imperative

The fundamental moral command requires that one act only according to a maxim that can simultaneously be willed as a universal law.

Hypothetical imperatives command actions as a means to attain something else desired, whereas categorical imperatives represent actions as objectively necessary in themselves. The universal law formulation requires testing whether a personal maxim can logically exist as a universal law of nature without contradicting itself. A man in distress considers making a false promise to borrow money without intending to repay it. When tested as a universal law, promising would destroy itself because no one would believe any promise made.

You can test any proposed action by following these steps:

• Identify the maxim of the proposed action.
• Transform the maxim into a universal law of nature.
• Check whether the universalized maxim is consistent with itself or creates a contradiction.

Every rational being exists as an end in himself and must always be treated as such, never merely as a means. Objects of inclinations have only conditioned value, but rational beings are designated as persons because their nature marks them out as ends in themselves. This imposes a strict limit on the arbitrary use of any rational being and serves as an objective principle for all practical laws.

Act in such a way that you treat humanity, whether in your own person or in the person of another, always at the same time as an end and never simply as a means.

Prima Facie Duties

Moral principles are not absolute imperatives, but rather prima facie duties whose application depends on circumstances and can be overridden by more binding moral duties.

A prima facie duty is an objective feature of a situation where an act would be a proper duty if it did not conflict with another morally significant duty of the same or higher weight. Determining actual duty requires studying the situation fully until one discerns which duty is most incumbent. A prima facie duty to tell the truth is overridden by the duty to save an innocent life when a murderer asks for the hiding place of an intended victim.

W. D. Ross divides prima facie duties into six distinct categories based on past acts, distributions of happiness, potential to improve others or oneself, and the avoidance of injury. You must navigate these obligations by following specific guidelines:

• Fulfill duties resting on previous acts of one's own, specifically promises or implicit undertakings like not telling lies (duties of fidelity).
• Fulfill duties resting on previous wrongful acts (duties of reparation).
• Fulfill duties resting on services rendered by other people (duties of gratitude).
• Prevent or upset distributions of pleasure or happiness that do not accord with personal merit (duties of justice).
• Improve the condition of other beings regarding virtue, intelligence, or pleasure (duties of beneficence).
• Improve one's own condition regarding virtue or intelligence (duties of self-improvement).
• Refrain from injuring others as a distinct and more stringent negative duty (non-maleficence).

Non-maleficence functions as a distinctly separate and more stringent negative duty than beneficence.

Conclusion

Moral philosophy shows how competing frameworks of utilitarianism, deontology, and virtue ethics provide complementary lenses for ethical evaluation. You can use these diverse tools to navigate complex moral dilemmas rather than relying on a single absolute system.

1. Identify the core stakeholders and the immediate consequences of your action to weigh overall utility.
2. Examine the underlying rules and duties to ensure you respect the intrinsic rights of rational beings.
3. Evaluate your long-term character and the virtues you cultivate through your habitual choices.
4. Test your maxim for universal consistency to ensure your personal conduct aligns with impartial moral law.
