PROP. III. An emotion, which is a passion, ceases to be a passion, as soon as we form a clear and distinct idea thereof.
Proof.—
An emotion,
which is a passion,
is a confused idea
(by the general Def. of the Emotions).
If, therefore,
we form a clear
and distinct idea
of a given emotion,
that idea
will only be distinguished
from the emotion,
in so far as
it is referred
to the mind only,
by reason
(II. xxi., and note);
therefore (III. iii.),
the emotion will cease to be
a passion. Q.E.D.
Corollary—
An emotion therefore becomes
more under our control,
and the mind
is less passive
in respect to it,
in proportion
as it is more
known to us.
