Soul of learning
A man should feel confident concerning his soul, who has renounced those pleasures and fineries that go with the body, as being alien to him, and considering them to result more in harm than in good, but has pursued the pleasures that go with learning and made the soul fine with no alien but rather its own proper refinements, moderation and justice and courage and freedom and truth; thus he is ready for the journey to the world below, ready to go when Fate calls him.
Socrates (469-399 BC).
