Excerpts from Hobbes' Thucydides
It need not be doubted, but from such a master Thucydides was sufficiently qualified to have become a great demagogue, and of great authority with the people. But it seemeth he had no desire at all to meddle in the government: because in those days it was impossible for any man to give good and profitable counsel for the commonwealth, and not incur the displeasure of the people. For their opinion was such of their own power, and of the facility of achieving whatsoever action they undertook, that such men only swayed the assemblies, and were esteemed wise and good commonwealth's men, as did put them upon the most dangerous and desperate enterprizes. Whereas he that gave them temperate and discreet advice, was thought a coward, or not to understand, or else to malign their power.
And no marvel: for much prosperity (to which they had now for many years been accustomed) maketh men in love with themselves; and it is hard for any man to love that counsel which maketh him love himself the less.
And it holdeth much more in a multitude, than in one man. For a man that reasoneth with himself, will not be ashamed to admit of timorous suggestions in his business, that he may the stronglier provide; but in public deliberations before a multitude, fear (which for the most part adviseth well, though it execute not so) seldom or never sheweth itself or is admitted.
By this means it came to pass amongst the Athenians, who thought they were able to do anything, that wicked men and flatterers drave them headlong into those actions that were to ruin them; and the good men either durst not oppose, or if they did, undid themselves.
Thucydides therefore, that he might not be either of them that committed or of them that suffered the evil, forbore to come into the assemblies; and propounded to himself a private life, as far as the eminency of so wealthy a person, and the writing of the history he had undertaken, would permit.
