@sei.come.sei: Two thousand years ago, pilgrims climbed Mount Parnassus to reach the Temple of Apollo at Delphi. Before they could consult the Oracle, they passed beneath an inscription carved into stone: "Know Thyself." Generations of philosophers took this as a call to introspection: Sit quietly. Examine your thoughts. Trust what you find inside. Mercier's work suggests they had it backwards. The reasoning feels objective. But the direction was set before you started thinking.
