of command upon any pretence whatever,
and are so ready to usurp upon dominion, every one does so naturally
aspire to liberty and power, that no utility whatever derived from the
wit or valour of those he employs ought to be so dear to a superior as a
downright and sincere obedience. To obey more upon the account of
understanding than of subjection, is to corrupt the office of command
--[Taken from Aulus Gellius, i. 13.]--; insomuch that P. Crassus, the same
whom the Romans reputed five times happy, at the time when he was consul
in Asia, having sent to a Greek engineer to cause the greater of two
masts of ships that he had taken notice of at Athens to be brought to
him, to be employed about some engine of battery he had a design to make;
the other, presuming upon his own science and sufficiency in those
affairs, thought fit to do otherwise than directed, and to bring the
less, which, according to the rules of art, was really more proper for
the use to which it was designed; but Crassus, though he gave ear to his
reasons with great patience, would not, however, take them, how sound or
convincing soever, for current pay, but caused him to be well whipped for
his pains, valuing the interest of discipline much more than that of the
work in hand.

Notwithstanding, we may on the other side consider that so precise and
implicit an obedience as this is only due to positive and limited
commands. The employment of ambassadors is never so confined, many
things in their management of affairs being wholly referred to the
absolute sovereignty of their own conduct; they do not simply execute,
but also, to their own discretion and wisdom, form and model their
master's pleasure. I have, in my time, known men of command checked for
having rather obeyed the express words of the king's letters, than the
necessity of the affairs they had in hand. Men of understanding do yet,
to this day, condemn the custom of the kings of Persia to give their
lieutenants and agents so little rein, that, upon the least arising
difficulties, they must fain have recourse to their further commands;
this delay, in so vast an extent of dominion, having often very much
prejudiced their affairs; and Crassus, writing to a man whose profession
it was best to understand those things, and pre-acquainting him to what
use this mast was designed, did he not seem to consult his advice, and in
a manner invite him to interpose his better judgment?
