Khalil Gibran

My crown is called content, a crown that seldom kings enjoy.
William Shakespeare

There will be no end to the troubles of states, or of humanity itself, till philosophers become kings in this world, or till those we now call kings and rulers really and truly become philosophers, and political power and philosophy thus come into the same hands.
Plato

'The time has come,' the walrus said, 'to talk of many things: of shoes and ships - and sealing wax - of cabbages and kings.'
Lewis Carroll
