Cover art for Cave lyrics by Muse

This song always makes me think of Plato's Cave. Plato was a student of Socrates, and Socrates, an incredible philosopher, was sentenced to death for corrupting the youth. Plato's Cave is often considered allegory for the execution of Socrates. The Cave is about men who have been trapped inside a cave all their lives, seeing only shadows and never real light. One of their number escapes, sees the light of the sun, and the true nature of the world. The man returns to the cave, only to be killed by those who say he speaks heresy. This song is sung by those who are in their cave.
