Philosophy is an academic discipline that exercises reason and logic in an attempt to understand reality and answer fundamental questions about knowledge, life, morality and human nature. The ancient Greeks, who were among the first to practice philosophy, coined the term, which means “love of wisdom.” Those who study philosophy are called philosophers. Through the ages, philosophers have sought to answer such questions as, what is the meaning and purpose of life? How do we know what we know? Does God exist? What does it mean to possess consciousness? And, what is the value of morals?
