3 - The Four Elements

The four classical elements - earth, air, water and fire - dates back to the sixth century B.C.E. It was believed that all of nature consisted of these four basic building blocks, each of which displaying the properties hot or cold, dry or wet. Today, we know much more about the inner workings of matter, but these four elements continue to play an important role as they have forever influenced classical philosophy, psychology, astrology, alchemy and magic.
