"And let no man think it pusillanimous that many states should hesitate to attack a single city.
For they also have allies not less numerous than ours who pay tribute; and war is a matter not so much of arms as of money, for it is money alone that makes arms serviceable, especially when an inland opposes a maritime power.
Let us therefore provide ourselves with money first, instead of being carried away prematurely by the eloquence of our allies; and, just as it is we who shall bear the greater part of the responsibility for the consequences, whether for good or evil, so let it be our task also calmly to get some forecast of them.
"And so be not ashamed of the slowness and dilatoriness for which they censure us most; for speed in beginning may mean delay in ending, because you went into the war without preparation, and, moreover, in consequence of our policy we have ever inhabited a city at once free and of fairest fame.
And, after all, this trait in us may well be in the truest sense intelligent self-control, for by reason of it we alone do not become insolent in prosperity or succumb to adversity as much as others do; and when men try to goad us by praise into dangerous enterprises against our better judgment, we are not carried away by their flattery, or, if anyone goes so far as to attempt to provoke us to action by invective, we are none the more moved to compliance through vexation.
