e first and second Motion, there is no
Interval, but between the second and third there is, in order to see
where the Enemy gives Light: This Interval must be shorter or longer
according as your Disposition or Practice is more or less.

_Of the Good Effects of a nice Discernment of the Eye._

In Fencing, there is the Foreseen, and the Unforeseen; the Foreseen is
the Effect of the Understanding and of the Will, and the Unforeseen is
the Effect of the Discernment of the Eye, and of Custom; which being
upheld by this Quality, has no sooner discerned an Action or Opening of
the Enemy, than all the Parts which are to act, display themselves to
oppose or attack him, as if they depended on the Eye. To be convinced of
this Truth, you may reflect on READING, wherein, as soon as the Eye has
discerned the Words, the pronouncing them follows as quick as in a
studied Discourse; the Eye and Tongue being so disposed by Custom, as to
do it without immediately reflecting. Indeed before they cou'd arrive to
this, the Understanding and the Will were necessary, which having been
united for a certain Time, have communicated such a Habit to these
Parts, as to make them act as it were of themselves.

In order to acquire this Quality in Fencing, it is necessary that the
Master, in his Lessons, shou'd shew what Opportunities are to be
favourably laid hold of, two opposite Actions at one and the same Time,
That whilst he is uncovering some Part of his Body, he cannot, at the
same Instant, parry, because by the Parade, it must be covered; so that
by making them make their Thrusts, and other Motions, by the Discernment
of the Eye, they find themselves by Practice ready to oppose all the
Motions of the Antagonist without the Assistance of the Will. This
Method is indeed a little more tedious in the Beginning, but it
afterwards becomes shorter and more certain.

If you have not had Practice enough to make the Discernment of the Eye
thus habitual, you must observe what Motions your Action causes in the
Adversary, by making a Half, or Home-thrust, in order to discover
whether the Enemy has recourse to the Parade, or to the Time: If he goes
to parry, you must observe his Manner, in order to make a Feint
resembling the same Thrust, and to push at the Part where you observed
him to give the Light; and if he goes to the Time, you also make a
Feint, preparing yourself for the parade and Rispost, or to take a Time
contrary to his.
