I think the two things most opposed to good counsel are haste and passion; haste usaully goes hand in hand with folly, passion with coarseness and narrowness of mind.
ThucydidesWith reference to the narrative of events, far from permitting myself to derive it from the first source that came to hand, I did not even trust my own impressions, but it rests partly on what I saw myself, partly on what others saw for me, the accuracy of the report always being tried by the most severe and detailed tests possible. My conclusions have cost me some labour from the want of coincidence between accounts of the same occurrences by different eye-witnesses, arising sometimes from imperfect memory, sometimes from undue partiality for one side or the other.

ThucydidesSome legislators only wish to vengeance against a particular enemy. Others only look out for themselves. They devote very little time on the consideration of any public issue. They think that no harm will come from their neglect. They act as if it is always the business of somebody else to look after this or that. When this selfish notion is entertained by all, the commonwealth slowly begins to decay.
