(Pericles:) [A] man's counsel cannot have equal weight or worth, when he alone has no children to risk in the general danger. (Book 2 Chapter 44.3) - Thucydides

Themistocles was a man whose natural force was unmistakable; this was the quality for which he was distinguished above all other men;from his own native acuteness, and without any study either before or at the time, he was the ablest judge of the course to be pursued in a sudden emergency,and could best divine what was likely to happen in the remotest future. Whatever he had in hand he had the power of explaining to others, and even where he had no experience he was quite competent to form a sufficient judgment;no one could foresee with equal clearness the good or evil event which was hidden in the future.In a word, Themistocles, by natural power of mind and with the least preparation, was of all men the best able to extemporise the right thing to be done.

(Book 1 Chapter 138.3)

(Pericles:) And do not imagine that you are fighting about a simple issue, freedom or slavery; you have an empire to lose, and there is the danger to which the hatred of your imperial rule has exposed you.

Neither can you resign your power, if, at this crisis, any timorous or inactive spirit is for thus playing the honest man. For by this time your empire has become a tyranny which in the opinion of mankind may have been unjustly gained, but which cannot be safely surrendered.

(Book 2 Chapter 63.1-2)

We all look with distaste on people who arrogantly pretend to a reputation to which they are not entitled; but equally to be condemned are those who, through lack of moral fibre, fail to live up to the reputation which is theirs already.
