Overview
Every day of your life is spent surrounded by mysteries that involve what appear to be rather ordinary human behaviors. What makes you happy? Where did your personality come from? Why do you have trouble controlling certain behaviors? Why do you behave differently as an adult than you did as an adolescent? Since the start of recorded history, and probably even before, people have been interested in answering questions about why we behave the way we do.
Many fields—including philosophy, psychology, and even theology—are focused on finding explanations. However, it’s only in recent decades that researchers have begun to approach, understand, and solve the mysteries of emotion, thought, and behavior. The result is a more solid understanding of what it means to be human, providing a stronger foundation for living effectively with others and grasping their intricate behaviors and quirks.
