Two Theories of Moral Rightness
The exploration of what constitutes a morally right action is a crucial topic in ethical
philosophy. Two influential philosophers who have significantly shaped moral theory are Immanuel
Kant and John Stuart Mill. Each offers distinct and compelling viewpoints. While both Kant and
Mill sought to establish rational principles for moral decision-making, their approaches diverge
sharply on how to determine what is right. Mill’s Utilitarianism (1861) prioritizes the outcomes of
actions, whereas Kant’s Groundwork of the Metaphysics of Morals (1785) grounds morality in duty
and universal law.
By examining Mill’s criteria for higher and lower pleasures, analyzing how each
philosopher resolves conflicts between duty and consequences, and exploring how their insights can
be applied to contemporary ethical challenges, we can better appreciate the enduring relevance of
both frameworks.
Kant’s seminal work, "Groundwork of the Metaphysics of Morals," introduces a
deontological framework, which posits that morality is based on duty and a universal moral law. In
contrast, Mill’s "Utilitarianism" adopts a teleological approach, determining moral rightness by
evaluating the consequences of actions in terms of their ability to promote happiness and reduce
suffering. Although both philosophers seek to establish a rational basis for ethics, their core
principles regarding moral worth differ markedly.
Immanuel Kant argues that the only intrinsically good quality is a good will. While
attributes such as intelligence, courage, and wealth can be beneficial, they may lead to harmful
outcomes if not guided by moral intent. In Kant’s view, goodwill is valuable in itself, regardless of
the consequences it produces. He emphasizes that true moral goodness is rooted in the intention to
act out of duty, rather than the success of the action.
For Kant, an action gains moral significance only when it is performed out of respect for
moral law, which transcends personal desires, emotions, or self-interest. This perspective
encourages individuals to reflect deeply on their motivations and highlights the importance of
acting with integrity and purpose.
Kant asserts that the moral worth of an action lies in its motive, specifically the will's
commitment to duty for its own sake. He defines “duty” as the necessity of acting out of reverence
for the law. This reverence is not simply an emotional feeling but a rational acknowledgment of the
authority that moral law holds over one's inclinations. To act morally means recognizing and
submitting to this law, viewing it as binding on all rational beings.
Kant formalizes this principle through his famous categorical imperative, which states: “Act
only according to that maxim whereby you can at the same time will that it should become a
universal law.” This test ensures that moral actions are universally consistent and free from
contradiction. By considering whether one’s rule of action could be willed as a universal law,
individuals can determine if their conduct respects the rational dignity of all persons.
In contrast, John Stuart Mill defines morality through the principle of utility, also known as
the greatest happiness principle. According to Mill, actions are considered right insofar as they
promote happiness and wrong if they produce the opposite. Here, “happiness” is understood as
