"Male cuncta ministrat
Impetus."

["Impulse manages all things ill."--Statius, Thebaid, x. 704.]

He who therein employs only his judgment and address proceeds more
cheerfully: he counterfeits, he gives way, he defers quite at his ease,
according to the necessities of occasions; he fails in his attempt
without trouble and affliction, ready and entire for a new enterprise;
he always marches with the bridle in his hand. In him who is intoxicated
with this violent and tyrannical intention, we discover, of necessity,
much imprudence and injustice; the impetuosity of his desire carries him
away; these are rash motions, and, if fortune do not very much assist,
of very little fruit. Philosophy directs that, in the revenge of
injuries received, we should strip ourselves of choler; not that the
chastisement should be less, but, on the contrary, that the revenge may
be the better and more heavily laid on, which, it conceives, will be by
this impetuosity hindered. For anger not only disturbs, but, of itself,
also wearies the arms of those who chastise; this fire benumbs and wastes
their force; as in precipitation, "festinatio tarda est,"--haste trips
up its own heels, fetters, and stops itself:

"Ipsa se velocitas implicat."--Seneca, Ep. 44

For example, according to what I commonly see, avarice has no greater
impediment than itself; the more bent and vigorous it is, the less it
rakes together, and commonly sooner grows rich when disguised in a visor
of liberality.
