Thucyclides

"Of all manifestations of power, restraint impresses men the most. "

"The bravest are surely those who have the clearest vision of what is before them, glory and danger alike, and yet notwithstanding go out to meet it. "

"The strong do what they have to do and the weak accept what they have to accept. "

"Those who really deserve praise are the people who, while human enough to enjoy power, nevertheless pay more attention to justice than they are compelled to do by their situation. "
