The word "psychology" is the combination of two terms - study (ology) and soul (psyche), or mind. The derivation of these words from the Latin provides a clear and obvious meaning: The study of the soul or mind. Today, psychology generally refers to the study of mind and behavior.
If psychology interests you, you have something in common with the ancient Greek philosophers. They asked questions about the life of the mind: What is the relationship between mind and body? How can we tell if the world is really the way we think it is? Today's psychologists study all sorts of fascinating questions, such as: Why is learning a language as an infant easier than as a teenager? What are the roots of violence? What is the best way to help someone with an eating disorder such as anorexia or bulimia?
Other more important and global issues include: How do we best learn to be respectful to our environment? How might we all work together to make the world a more loving and peaceful place that welcomes diversity, respects differences, and celebrates life?
