On the False Embassy

Why are these the topics of inquiry? Your conclusions are derived from the ambassador’s reports: you reach a right decision if they are true, a wrong decision if they are false. The advice of ambassadors you regard as the more trustworthy because it is given by men who presumably understand their own mission.

No ambassador, then, ought ever to be convicted of defective or mischievous counsels. Thirdly, when he has been expressly instructed what to say and what to do by resolution of the Assembly, it is his duty to conduct his business according to such instructions. Very well; but how does the question of time arise? Because, men of Athens, in important transactions opportunities are often short-lived: once willfully surrendered and betrayed to the enemy, they cannot be recovered, do what you will.
