Welcome to the World of "Human Way of Life and Existence"

Hello! In this chapter, we will explore an eternal human theme: "How can we live a better life?" While "Ethics" might sound difficult, it is actually a very personal topic about thinking through "how to live true to myself." It might feel challenging at first, but don't worry! Let’s learn step-by-step, borrowing the wisdom of the great thinkers of the past.

1. Adolescence: A Time of Self-Discovery

As high school students, you are currently in the midst of "adolescence." It is a vital period of transition from childhood to adulthood.

Who Am I? Establishing "Identity"

The psychologist Erik Erikson called adolescence the period for establishing "identity" (self-sameness). This is about reaching a conviction of "This is who I am!" Additionally, Kurt Lewin described adolescents as "marginal men" (boundary people), capturing the sense of emotional instability that comes with being neither a child nor an adult.

【Key Point】
During adolescence, you experience "psychological weaning," where you seek independence from your parents and start asserting yourself strongly. This is an essential step in your growth!

Fun Fact:
The thinker Jean-Jacques Rousseau called adolescence a "second birth." He left behind the beautiful sentiment: "We are born twice: once to exist, and a second time to live."

2. Greek Philosophy: The Love of Wisdom

It was the ancient Greek philosophers who first began to think logically about "how to live."

Socrates: "The Wisdom of Ignorance"

Socrates taught the importance of "the wisdom of ignorance" (knowing that you know nothing). By admitting that you don't know everything, you become motivated to seek the truth. Through dialogue (the Socratic method), he urged people to show "care for the soul."

Plato and Aristotle

Socrates' student, Plato, pursued the ideal world of "Ideas." On the other hand, his student Aristotle valued the real world and considered the highest good for humans to be "happiness (eudaimonia)." He also described humans as "political animals" (polis-oriented animals), emphasizing the importance of living within a society.

【Section Summary】
The Greek philosophers didn't just want to survive; they pursued the goal of "living well."

3. Religion and Human Life

People all over the world use religious teachings as a guide for how to live.

Christianity: The Teachings of Love

Jesus preached God's absolute love (agape) and taught "brotherly love," urging people to love their neighbors as themselves. He valued the state of the heart more than merely following formal rules.

Buddhism: The Heart of Compassion

The Buddha (Shakyamuni) believed that suffering in this world stems from attachment. He realized that everything has a cause (dependent origination) and emphasized the heart of "compassion," caring for all living things.

Islam: The Teachings of Equality

Islam teaches absolute devotion to the one God, Allah, and emphasizes that all believers are equal before Him. By practicing the Six Articles of Faith and Five Pillars of Islam, believers strengthen the bonds of their community.

【Common Misconception】
People often think "religion = following strict rules," but at the root of every religion is "compassion for others" and "peace of mind."

4. Modern Thought: Freedom and Human Dignity

In the modern era, the movement to judge things based on "individual reason" grew stronger.

Kant: The Morality of Duty

German philosopher Immanuel Kant believed that acting according to a pure sense of duty—"do it because you ought to"—(categorical imperative), rather than cost-benefit analysis, is the true mark of human dignity (personality).

Utilitarianism: Calculating Happiness

Bentham and Mill advocated for utilitarianism, known by the phrase "the greatest happiness for the greatest number." They believed that maximizing the happiness of society as a whole is the standard for right action.

Analogy:
Instead of just giving a treat to one person, thinking of a way that everyone can smile equally is the core idea of utilitarianism.

5. Existentialism: Choosing Your Own Way of Life

As we approach the contemporary era, existentialism emerged, emphasizing "this irreplaceable self" rather than "a person as a member of an organization."

Sartre: "Existence Precedes Essence"

Sartre taught, "Humans have no predetermined purpose (essence). Because of this, we must choose how to live and create ourselves." Being free comes with responsibility, but it also means you are free to design your own life.

【Key Point】
Kierkegaard emphasized overcoming despair to live as a "single individual standing before God."

Summary: Finding Your Own "Way of Being"

As we have seen, the answer to "how one should live" varies by time and place.

Adolescence is an important preparation period for self-reflection.
Greek philosophy provides hints on thinking about "goodness" through reason.
Religion offers the heart of "love" and "compassion" for others.
Modern thought focuses on individual "freedom" and "responsibility."

These are all part of your "mental toolkit" for the life ahead of you. It’s okay if you don't understand everything right now. Try to incorporate the ideas that resonate with you into your own life, little by little.

A final word:
Studying ethics isn't just for taking tests. When you are lost or struggling, you are sure to find words here that will give you support. Let's do our best together!
