A good leader can engage in a debate frankly and thoroughly, knowing that at the end he and the other side must be closer, and thus emerge stronger. You don't have that idea when you are arrogant, superficial, and uninformed.

A military leader must possess as much character as intellect. Men who have a great deal of intellect and little character are the least suited; they are like a ship whose masts are out of proportion to the ballast; it is preferable to have much character and little intellect.
