The leader holds his position purely because he is able to appeal to the conscience and to the reason of those who support him, and the boss holds his position because he appeals to fear of punishment and hope of reward. The leader works in the open, and the boss in covert. The leader leads, and the boss drives.

Theodore Roosevelt (1858-1919) American politician, statesman, conservationist, writer, US President (1901-1909)
