As Mike and Laura suggest, Empedocles was a very influential thinker. His notion of the four elements was considered cutting-edge scientific theory for centuries after his death, and underpins the related theory of the four humours. The general theory is that all of creation, all physical matter, is comprised of four basic elements: air, water, earth and fire. Each element results from the combination of two basic attributes, hotness/coldness and moistness/dryness. Or in the words of a revered classical author:
Here's an easier rule of thumb:
Over the years, hot-shot thinkers developed a sort of correspondence between this vision of the cosmos and the cosmos 'within'--that is, our individual human bodies. Like the greater span of creation, each of our bodies was seen as made up four elements, defined in anatomy as the 'humours.' These humours were thought of as bodily fluids which are to the human body what the elements are to the common matter of the earth. Thus, each element corresponds to one of these basic bodily humours:
Element | Humour | Common Quality | |
Earth | Melancholy | Cold and Dry | |
Water | Phlegm | Cold and Moist | |
Air | Blood | Hot and Moist | |
Fire | Choler | Hot and Dry |
Think on this: if you do your Shakespeare reading (which I have no doubt you ALL have), you still see this basic notion of four basic elements bandied about as common knowledge. That's a full 1900 years or so after Empedocles lived!
The sad thing is, he was completely wrong. So much for the wisdom of the ages.
The other interesting fact about Empedocles is that he is said to have committed suicide by leaping into the volcano Etna. I got your hot and dry right here, Empedocles!!!
