Morality

For a topic as subjective as morality, people sure have strong beliefs about what's right and wrong. Yet even though morals can vary from person to person and culture to culture, many are practically universal, as they result from basic human emotions. We may think of moralizing as an intellectual exercise, but more frequently it's an attempt to make sense of our gut instincts.

Personality

Questions of personality have vexed mankind from the dawn of personhood: can people change? How do others perceive me? What is the difference between normal and pathological behavior? One's personality is so pervasive and all-important that it presents a clinical paradox of sorts: it is hard to assess our own personality, and impossible to overlook that of others.
