Foundations of Philosophical Ethics and Human Flourishing

The Purpose and Nature of Ethics

1. Why Study Ethics?

Every discipline has a purpose. Ethics, according to Adela Cortina, helps us commit to a happy and good life—a life:

  • Open to hope,
  • Guided by justice,
  • And oriented toward human flourishing.

This aligns with the classical tradition, where ethics concerns happiness, the good life, justice, and hope. Ethics is also a science that guides human action toward the ultimate end of human life.

2. Can Ethics Be Learned by Imitation Alone?

Unlike animals (e.g., tropical birds that must learn by imitation), humans cannot acquire ethics merely through family habits, social imitation, or media influence. Ethics requires:

  • Reflection,
  • Rational inquiry,
  • And systematic study.

Thus, ethical knowledge is not reducible to custom; it demands the involvement of reason.

3. Etymology and Classical Meaning

The Greek term ethos means “character” or “personal disposition”—a second nature formed through habits. This character is not temperament (which is innate and unchangeable), but the acquired moral identity shaped by repeated actions, which becomes either virtue (good habits) or vice (bad habits).

Understanding ethics requires understanding the good, virtue, and the formation of character. Without this, we cannot distinguish virtuous acts from vicious ones.

4. Ethics and the Human Good

Classical thought, especially Aristotle, holds that all humans share the same nature, tend toward happiness, and possess a basic idea of the good. Ethics studies the behaviors that help humans approach their ultimate end: the greatest possible happiness.

This reflection is both individual (personal moral growth) and collective (shared human nature and common good). Modern thought complicates this by questioning human nature, the universality of the good, and the idea of a shared final end (e.g., Kant’s shift from happiness to duty, or contemporary transhumanism).

5. Ethics as a Philosophical Science

Ethics is a rational and systematic investigation of human behavior in light of the ultimate end. It is not opinion, ideology, intuition, or improvisation. It has:

  • Principles: Nature and the good.
  • Ends: Happiness.
  • Methods: The acquisition of virtue.

This is why ethics has been a philosophical discipline since Aristotle’s Nicomachean Ethics, Eudemian Ethics, and Magna Moralia.

6. Spontaneous vs. Philosophical Moral Knowledge

Spontaneous (pre-philosophical) moral knowledge is shared by all humans. It involves an intuitive grasp of basic goods, empathy, and the ability to judge simple moral situations. However, it is limited and can be distorted by pride, fear, resentment, prejudice, or self-interest.

Philosophical ethical knowledge refines and strengthens spontaneous moral awareness. It identifies universal principles, clarifies the hierarchy of goods, and exposes subjective biases. Thus, philosophical ethics is necessary to understand the moral life with clarity and avoid self-deception.

Relationship Between Ethics and Other Sciences

1. Ethics as a Human Science

Ethics studies human behavior, just like psychology, sociology, anthropology, and theology. However, its formal object—the perspective from which it studies behavior—is different. Philosophical ethics examines human action from a standpoint of totality, unity, and ultimate ends, whereas positive sciences study behavior from empirical, descriptive, and partial perspectives.

2. Ethics and Psychology

Psychology studies the nature and genesis of free acts using empirical methods. It can explain how addictions form or how freedom is compromised, but it cannot determine whether an action is morally right or establish universal moral norms. Ethics evaluates free actions in light of rational principles and the ultimate human good. While psychology informs ethics, ethics provides the normative judgment.

3. Ethics and Sociology

Sociology describes and measures social facts, such as corruption rates or social norms. However, it cannot determine whether corruption is morally wrong or define the human good. Ethics uses sociological data to understand context but evaluates social structures in light of the ultimate end of human beings.

4. Ethics and Theology

There are two kinds of moral knowledge: Philosophical ethics (natural and rational) and Theological ethics (based on revelation and faith). Theological ethics studies behavior as oriented toward communion with God, adding theological virtues (faith, hope, charity) to the cardinal virtues. They are distinct but complementary; revelation has historically enriched philosophical reflection on human dignity.

5. Ethics, Metaphysics, and Anthropology

Metaphysics studies the ultimate causes and first principles of reality. Anthropology studies the human person, examining nature, freedom, and rationality. Ethics draws from both: if man is a real being (metaphysics) with a personal nature (anthropology) and a natural inclination toward a final end, then ethics can determine which actions lead toward that end.

Theoretical and Practical Aspects of Ethics

1. Ethics as a Philosophical Discipline

Ethics belongs to philosophy, which is divided into Theoretical philosophy (studying what things are) and Practical philosophy (studying what we should do). These dimensions are unified: you cannot know what humans should do without knowing what humans are.

2. Classical vs. Modern Perspectives

Classical ethics assumes human nature is knowable and grounded in the ultimate good (eudaimonia). Modern ethics often questions the knowability of human nature, leading to a lack of stable foundations for practical ethics. Freedom is often reduced to the absence of coercion rather than an orientation toward the true good.

3. Freedom and Moral Responsibility

Only free actions can be morally evaluated. Human acts proceed from deliberate will and reason; they are morally imputable. Acts of man are instinctive or involuntary (e.g., heartbeat) and are not subject to moral evaluation.

4. True Goods vs. Apparent Goods

Every human action seeks some good, but humans often mistake apparent goods for real goods. Ethics helps distinguish between them. Ethics is practical because it guides conduct and normative because it establishes universal principles, such as respect for life.

Personal and Political Ethics

1. Two Ethical Domains, One Human Subject

Human beings live in society, making political ethics necessary. Personal ethics is grounded in metaphysics and anthropology. The question is whether political ethics also orients itself toward the same end: happiness.

2. Two Extreme Models

Model A: Political ethics as a copy of personal ethics, where the State imposes a complete ethical system. This leads to unjustifiable interference in personal freedom. Model B: Minimalist political ethics, where ethics is reduced to rules of justice and all other questions are private. This eliminates philosophical reflection on the human good from public life.

3. The Classical Solution: The Common Good

For Aristotle and Aquinas, humans are zoon politikon (naturally social). The individual good and the common good are two dimensions of the same human good. Political authority must respect the ethical convictions of citizens while preventing destructive errors that threaten the community.

The Constitution of Ethics as a Discipline

1. Two Sources of Moral Knowledge

Ethical knowledge arises from Spontaneous moral knowledge (immediate awareness of good) and Philosophical moral knowledge (systematic reflection). Ethics becomes a philosophical discipline when spontaneous experience is illuminated by rational reflection to detect illusions and subjective distortions.

2. The Debate: Which Comes First?

Hume argues moral experience is the only source (feelings), while Enlightenment rationalists argue for abstract deduction. The realistic position (classical tradition) holds that moral experience comes first but requires reflection to be understood, corrected, and integrated into a coherent vision.

3. Perspectives on the Object of Ethics

  • The Best Life (Classical): Focuses on virtue and flourishing.
  • Moral Law (Deontological): Focuses on duty and external norms (Kant).
  • Social Collaboration: Focuses on procedural consensus (Rawls, Habermas).
  • Naturalistic Description: Describes behavior without prescribing norms.
  • Utilitarianism: Focuses on producing the best consequences (pleasure/utility).

Philosophical Foundations of Morality

1. Empiricism (Hume)

Empiricism rejects metaphysical knowledge and reduces knowledge to sensations. According to Hume’s Law, one cannot derive an “ought” from an “is.” This makes ethics subjective and fragmented, as values are seen as sentiments rather than rational facts.

2. Philosophy of Being (Realism)

Realism (Aristotle and Aquinas) holds that human knowledge adapts to reality. Being and good are convertible: what perfects being is good. Ethics is grounded in the natural law and the teleological structure of human action.

3. Transcendental Philosophy (Kant)

Kant argues that moral law arises from pure reason, not human nature. Ethics becomes autonomous and formal, disconnected from the concepts of telos, virtue, or happiness. Freedom is understood as indifference rather than choosing the objective good.

4. Final Insight

Ethical theories depend on how they understand being, knowledge, and human nature. Empiricism leads to subjectivism, Transcendentalism to formalism, and Realism to virtue ethics. The foundation of morality is inseparable from metaphysics and anthropology.
