The Philosopher's Stone is an archetypal element, the element of all elements. In some ways it functions as an abstraction--there is no stone in history that you can hold in the palm of your hand which can turn mercury into gold. But as with many archetypes, it "creeps" into objective reality. If we understand the philosopher's stone to be a symbol, it symbolizes the power to transform. It was a symbol used (and belived in literally) by the "thinkers" of past ages -- a person not inclined to believe that the pope is infallible might still believe in the existence of the philosopher's stone. The pursuit of this power of transformation is ONE of the driving elements of science.
So let's talk science. We know that gold is an element. I can't therefore change sodium or calcium or mercury into gold, because each element has its own unique atomic structure. But wait!!! What if we can learn how to split and fuse atoms?????? And in fact we have. Next time you watch video of a mushroom cloud over Nagasaki, think "Philosopher's Stone." Just think about the enormity of the POWER, its ability to light our cities, or to kill millions... If the vision doesn't chill you to the bone, you are probably not INFJ.

When I pause to think about it, I suddenly remember all the science ficiton versions of the Tower of Babel. We don't have the morality yet to handle having the powers of the gods, and toying with the infrastructure of nature is going to come back at us in the face. We shall see.
And so it is with great awe, fear, and tripidation that I present to you, the Philosopher's Stone:
