The greatest riddle of all is one that doesn't deal with St. Ives or math. No reading in between the line of a simple sentence to draw out the answer. No letter tricks or English vocabulary.
The greatest riddle is the humanities search for the truth about life and purpose. To feel like they belong. To feel like they are not alone. To feel like there is a meaning to the everyday rat race.
Psychologist race to find the answer. But can't.
People get more money to fill the emptiness. But it doesn't.
People climb the corporate ladder to get purpose. But don't find it.
