Arthur is quiet, serious, and earns success by thoroughness and independability. He's practical, matter-of-fact, realistic, and responsible. He decides logically what should be done and works toward it steadily, regardless of distractions. 

He takes pleasure in making everything orderly and organized - his work, his home, his life.  He like to have his own space and to work within his own time frame. Loyal and committed to their values and to people who are important to them, he has not once revealed the location of a client or comrade.  He likes disagreements and conflicts, but does not force his opinions or values on others.  Wants an external life that is congruent with their values.  Curious, quick to see possibilities, can be catalysts for implementing ideas.
