in Pursuit of a Secret that destroys his Happiness if he
chance to find it.

An ardent Love is always a strong Ingredient in this Passion; for the
same Affection which stirs up the jealous Man's Desires, and gives the
Party beloved so beautiful a Figure in his Imagination, makes him
believe she kindles the same Passion in others, and appears as amiable
to all Beholders. And as Jealousy thus arises from an extraordinary
Love, it is of so delicate a Nature, that it scorns to take up with any
thing less than an equal Return of Love. Not the warmest Expressions of
Affection, the softest and most tender Hypocrisy, are able to give any
Satisfaction, where we are not persuaded that the Affection is real and
the Satisfaction mutual. For the jealous Man wishes himself a kind of
Deity to the Person he loves: He would be the only Pleasure of her
Senses, the Employment of her Thoughts; and is angry at every thing she
admires, or takes Delight in, besides himself.

Phaedria's Request to his Mistress, upon his leaving her for three Days,
is inimitably beautiful and natural.

and Artifice. If the Person he loves be cheerful, her Thoughts must be
employed on another; and if sad, she is certainly thinking on himself.
In short, there is no Word or Gesture so insignificant, but it gives him
new Hints, feeds his Suspicions, and furnishes him with fresh Matters of
Discovery: So that if we consider the effects of this Passion, one would
rather think it proceeded from an inveterate Hatred than an excessive
Love; for certainly none can meet with more Disquietude and Uneasiness
than a suspected Wife, if we except the jealous Husband.

But the great Unhappiness of this Passion is, that it naturally tends to
alienate the Affection which it is so solicitous to engross; and that
for these two Reasons, because it lays too great a Constraint on the
Words and Actions of the suspected Person, and at the same time shews
