And this, in proof of mental forecast, I must needs praise in him.
Holding to the belief that the more satraps there were who revolted
from the king the surer the gain to Hellas, he did not suffer himself
to be seduced, either by gifts or by the mightiness in his power, to
be drawn into bonds of friendship with the king, but took precaution
rather not to abuse their confidence who were willing to revolt.

And lastly, as beyond all controversy admirable, note this contrast:
First, the Persian, who, believing that in the multitude of his riches
he had power to lay all things under his feet, would fain have swept
into his coffers all the gold and all the silver of mankind: for him,
and him alone, the costliest and most precious things of earth. And
then this other, who contrariwise so furnished his establishment as to
be totally independent of every adventitious aid.[5] And if any one
doubts the statement, let him look and see with what manner of
dwelling-place he was contented; let him view the palace doors: these
are the selfsame doors, he might well imagine, which Aristodemus,[6]
the great-great-grandson of Heracles, took and set up in the days of
the return. Let him endeavour to view the furniture inside; there he
will perceive how the king feasted on high holy days; and he will hear
how the king's own daughter was wont to drive to Amyclae in a public
basket-carriage.[7] Thus it was that by the adjustment of expenditure
to income he was never driven to the commission of any unjust deed for
money's sake. And yet if it be a fine thing to hold a fortress
impregnable to attck, I count it a greater glory that a man should
hold the fortress of his soul inviolable against the assaults of
riches, pleasures, fears.
