What Do We Mean by the “Dark Side”?
1: What Do We Mean by the “Dark Side”?

Most of us think of ourselves as good people—reserving the concept of the “dark side” only for science fiction or psychopaths. But that’s not really the truth of human nature. We’ll begin to explore how the dark side relates both to our tendencies toward immorality and evil and to some of the most problematic aspects of the human condition.

Our Fundamental Nature: Good or Evil?
2: Our Fundamental Nature: Good or Evil?

Are people fundamentally good, fundamentally evil, or neither? To develop a sophisticated answer to this basic question, we reach back to a more than 2,000-year-old debate between great Confucian philosophers. Do you agree with optimism, pessimism, dualism, indifferentism, or individualism? Which theory of human nature speaks to you and frames your view of the world?

What Is Evil?
3: What Is Evil?

You probably have some ideas about what it means to be “evil.” But in order to fully examine the dark side of human nature, we need to go deeper—questioning both whether evil actually exists and what it means to call an action evil. Referencing a wide range of thinkers, some ancient, some contemporary, you’ll explore the ontological and conceptual aspects of evil.

Moral Monsters and Evil Personhood
4: Moral Monsters and Evil Personhood

Most of us have done something “bad” or immoral in our lives, although we wouldn’t consider ourselves evil. But where exactly is that line? What does it take for us to label a person evil? By considering four models of evil—the Evildoer, Dispositional, Affect, and Moral Monster models—you’ll begin to develop your own views of when an individual is, and is not, evil.

Evil and Responsibility
5: Evil and Responsibility

Are psychopaths responsible for their actions? You might be surprised to learn that many psychologists and philosophers think they are not, due to their inability to recognize important moral facts. Guided by a variety of philosophers, you will consider how much responsibility evil-doers can and should accept for their crimes—and in what ways they might not be so different from the rest of us.

Sin: Original and Otherwise
6: Sin: Original and Otherwise

How would you know if you had committed a sin, and what would its consequences be?

Dark Thoughts and Desires
7: Dark Thoughts and Desires

Have you ever daydreamed about doing harm to another person? If so, studies show you're certainly not alone. Are our darkest thoughts and desires simply a fundamental part of our human nature? Why can't we seem to suppress or eradicate them? Explore potential answers to these fascinating questions with help from 6th-century Tianti Buddhist philosophers and modern-day evolutionary psychologists.

Suffering and Its Causes
8: Suffering and Its Causes

Why do we suffer, and how can we avoid it? The Buddha addresses these questions directly in his Four Noble Truths.

But do the Buddha’s teachings carry truth for us in the 21st century? An evolutionary psychologist provides a fascinating answer.

31 min
The Problem of Expectation and Desire
9: The Problem of Expectation and Desire

We turn to the 2,000-year-old Hindu Bhagavad Gita to study the roles played by our desires and expectations, and why we are so often disappointed in our lives. But how could we live without desire and expectations? One path provided by the Gita—being so absorbed in an activity that we lose our sense of self—leads to the experience we know of today as “flow.”

32 min
The Fear of Death
10: The Fear of Death

We are all going to die. How do we respond to that knowledge? Learn why the Roman philosopher Lucretius believed that our fear of death drives us to act against our best interests. And why the Daoist philosopher Zhuangzi wondered if our negative view of death even makes sense. Either way, fearing death seems to be part of what it means to be human.

Existential Anxiety and the Courage to Be
11: Existential Anxiety and the Courage to Be

Have you ever wondered whether life has any meaning at all? Given the immensity of the universe, how could we be anything more than an inconsequential blip?

The Goodness of Grief
12: The Goodness of Grief

Could grief ever have a good side? If you've ever suffered its agony, you know grief can feel like the very darkest side of human nature.

Homo necans: Why Do We Kill?
13: Homo necans: Why Do We Kill?

Is there something in human nature that drives us to kill others or is it a biological aberration? Watching the news would certainly make you wonder. And if a drive to kill does exist, is it activated by nature or nurture—is it genetic or situational? Studies have supported both points of view. The shocking truth we do know is just how much we all have in common with those who kill.

Nightmares and the Dream Self
14: Nightmares and the Dream Self

Who are we in the worst of our dreams? Explore why Freud believed our dreams reveal important aspects of ourselves—both the conscious and unconscious.

Varieties of Self-Deception
15: Varieties of Self-Deception

When we hold two contradictory thoughts in our minds at the same time, have we become liars, lying to ourselves about something we know cannot be true? Or are we just harmless wishful thinkers?

Varieties of Ignorance
16: Varieties of Ignorance

Explore the concept of ignorance through the writings of two Indian philosophers who lived centuries apart, Shankara and Ramanuja. Is ignorance a lack of knowledge, or is it wrong knowledge?

Weakness of Will
17: Weakness of Will

Have you ever eaten a donut when you knew you shouldn't? Socrates would have been shocked! He didn't think it was possible for people to act against their own best interest. Explore many potential explanations for why we sometimes do what we said we never would. Is it a question of a simple failure to follow through on our intentions, or could we be suffering from ego depletion?

28 min
Luck and the Limits of Blame
18: Luck and the Limits of Blame

Two people go to a party, become legally drunk, and drive home. One kills a pedestrian, the other encounters no one. Should we judge them differently, or the same? Many philosophers have addressed the role of luck and its moral implications in our lives. As you explore their various perspectives, you might not find any easy answers. But you might think twice before placing blame.

Victim Blaming and the Just-World Hypothesis
19: Victim Blaming and the Just-World Hypothesis

In the Old Testament Book of Job, his friends blamed Job for the tragedies that befell him. After all, if the world is a fair and just place, then victims always get what they deserve, right?

Retribution and Revenge
20: Retribution and Revenge

We’ve all heard of people who decide to take the law into their own hands to exact revenge on a perpetrator who harmed them or someone they love—even if that person had already received society’s punishment.

The Elimination of Anger
22: The Elimination of Anger

If you could eliminate anger from your life, would you? Should you? Anger can be dangerous, but righteous anger can also be motivating.

23: Being Peaceful in a Troubled World

How can we find internal tranquility and remain peaceful in the midst of such a troubled world? It isn't easy, but it is possible.
