Q. Which is not a metal in Plato's Myth of Metals Theory?
Answer:
Platinum
Notes: Plato held that all human beings were born of earth, and their bodies were mixed with different metals: the philosophic - rational ones were made of gold, the spiritual - courageous ones of silver, and the appetitive ones of bronze. The myth was necessary to sustain the Ideal State, by convincing everyone of their rightful place in society.
