Introduction to Ethics and Logic

What is Ethics?

• Ethics is the study of guiding ideals, a good life, and how to treat each other.

Three Main Areas of Ethics

• Value Theory: Examines what constitutes a good life, what pursuits are worthwhile, and how to improve one's life.
• Normative Ethics: Investigates fundamental moral obligations, distinguishes virtues from vices, and analyzes the justification of means and ends in morality.
• Metaethics: Explores the nature of moral claims and principles, including their truth status, the possibility of moral wisdom, and the reasons for moral obligation.

Logic: Validity and Soundness

• Validity: Arguments that, if the premises are true, the conclusion necessarily follows are valid.
• Soundness: An argument that is both valid and has true premises is sound.

C.S. Lewis on "Likings and Loves for the Sub-Human"

• Types of Love: Lewis differentiates between gift-love (selfless service), need-love (based on benefits received), and appreciative love (love for its own sake).
• Need-Pleasures: Pleasures tied to a temporary condition, often lasting longer than the actual need, driven by self-interest.
• Appreciative Pleasures: Pleasures that are experienced for their own sake, indicating an appreciation for the object loved.
• Love of Sub-human: Lewis believes love can be genuine for animals, distinct from love for humans.
• Love of Country: Lewis warns against excessive patriotism, stating it can become a demoniac force.
• Love of Nature: Lewis describes a distinct form of love for nature, seeing it as an iconography or language of images, but cautions against it becoming a religion.

Alasdair MacIntyre on "Is Patriotism a Virtue?"

• Patriotism Defined: For MacIntyre, patriotism is loyalty to a nation, not blind, but based on its merits as a morally distinct community.
• Patriotism vs. Moral Good: Love for one's country based solely on its moral goodness is not, for MacIntyre, true patriotism, which encompasses gratitude for benefits received.
• Patriotism as a Virtue? MacIntyre sees patriotism as a virtue.
  • Modern Ethicist Perspective: They might argue against it, citing concerns with bias, hindered self-critique, lack of autonomy, and individualistic values.
  • Communitarian Perspective: Communitarians might support patriotism, emphasizing its role in shaping morality, motivating ethical behavior, and preserving the community.

C.S. Lewis on "Affection"

• Affection Defined: Affection, characterized by familiarity, warmth, non-demanding nature, stability, and inclusiveness, is a modest and humble love.
• Affection vs. Other Loves: Affection is less discriminating, blends need-love and gift-love, and is deeply rooted in familiarity, compared to friendship which is built on choice and mutual understanding.
• Dangers of Affection: These include an aversion to change, jealousy, and the dependence on affection alone.
• Limits of Affection: Personal beliefs, religious views, expression of affection depending upon the relationship, and jealousy can all limit its reach.

Aristotle on Ethics and Happiness

• Eudaemonia Refers to happiness and flourishing as the ultimate human goal.
• Virtue Ethics: Aristotle advocates for virtue ethics, which investigates the conditions for flourishing within a community and identifies the virtues or character traits that facilitate that flourishing.
• Intellectual Virtues: These include logic, understanding, and intellectual curiosity, and are crucial for ethical reasoning.
• Moral Virtues: They are virtues that involve navigating social interactions and include qualities like honesty, compassion, loyalty, selflessness patience, and temperance.

Moral Virtues: Definition and Components

• Moral Virtue: Aristotle describes moral virtue as a state of character that leads to appropriate actions and feelings, guided by practical wisdom and the golden mean.
• Four Components:
  • State of Character: A steady and chosen condition of the soul, influenced by character.
  • Actions and Feelings: Virtues inform both action and emotions.
  • The Mean: Virtue represents the balance between two vices, the excess and the deficiency.
  • The Good: Moral virtues promote what is good.

The Mean and Examples

• The Mean: Virtue always occupies the middle ground between two vices. It is the midpoint of the two extremes.
• Specific Examples:
  • Courage: The mean between rashness (excess) and cowardice (deficiency).
  • Liberality: The mean between prodigality (excess spending) and stinginess (excessive taking).
  • Honesty: The mean between empty vanity (excess pride) and undue humility (lack of pride).

Aristotle on Friendship

• Friendship as a Virtue: Friendship plays a significant role in ethical life, contributing to happiness.
• Friendship Defined: Reflects reciprocated goodwill and mutual awareness.
• Types of Friendship:
  • Friendship of Utility: Based on mutual benefit.
  • Friendship of Pleasure: Centered on shared enjoyment.
  • Friendship of Virtue: Focused on the good of the other person.
• Best Friendship: Aristotle emphasizes the superiority of friendships of virtue, as these prioritize the well-being of the other.
• Self-Love: Essential for ethical living, according to Aristotle, a good person will pursue their own good.
• Necessity of Friendship: Friendship is crucial for happiness, as it is a great external good.
• Virtue and Friendship: Virtue underpins complete friendship, as it is a result of a virtuous character and promotes shared virtue.

Immanuel Kant's Ethics

• Supreme Principle of Morality: Found in reason, not experience, it must be universal and applicable to all people.
