On objectivity (which is difficult, by the way).....

     The life of Darwin demonstrates how a turtle may outrun a hare, aided by extreme objectivity, which helps the objective person end up like the only player without a blindfold in a game of Pin the Tail on the Donkey.
     If you minimize objectivity, you ignore not only the lesson from Darwin but also from Einstein.  Einstein said that his successful theories came from "Curiosity, concentration, perseverance, and self-criticism."  And by self-criticism, he meant the testing and destruction of his own well-loved ideas.
