The Epicurean "Weltanschauung" is so modern! And no one has described this better than Stephen Greenblatt in The Swerve:
“Understanding the nature of things generates deep wonder. The realization that the universe consists of atoms and void and nothing else, that the world was not made for us by a providential creator, that we are not the center of the universe, that our emotional lives are no more distinct than our physical lives from those of all other creatures, that our souls are as material and as mortal as our bodies — all these things are not the cause for despair. On the contrary, grasping the way things really are is the crucial step toward the possibility of happiness. “
