We may see by what has been said, that Jealousy takes the deepest Root in Men of amorous Dispositions; and of these we may find three Kinds who are most over-run with it.

The First are those who are conscious to themselves of an Infirmity, whether it be Weakness, Old Age, Deformity, Ignorance, or the like.  These Men are so well acquainted with the unamiable Part of themselves, that they have not the Confidence to think they are really beloved; and are so distrustful of their own Merits, that all Fondness towards them puts them out of Countenance, and looks like a Jest upon their Persons.  They grow suspicious on their first looking in a Glass, and are stung with Jealousy at the sight of a Wrinkle.  A handsome Fellow immediately alarms them, and every thing that looks young or gay turns their thoughts upon their Wives.

A Second Sort of Men, who are most liable to this Passion, are those of cunning, wary, and distrustful Tempers.  It is a Fault very justly found in Histories composed by Politicians, that they leave nothing to Chance or Humour, but are still for deriving every Action from some Plot and Contrivance, for drawing up a perpetual Scheme of Causes and Events, and preserving a constant Correspondence between the Camp and the Council-Table.  And thus it happens in the Affairs of Love with Men of too refined a Thought.  They put a Construction on a Look, and find out a Design in a Smile; they give new Senses and Significations to Words and Actions; and are ever tormenting themselves with Fancies of their own raising:  They generally act in a Disguise themselves, and therefore mistake all outward Shows and Appearances for Hypocrisy in others; so that I believe no Men see less of the Truth and Reality of Things, than these great Refiners upon Incidents, [who [7]] are so wonderfully subtle and overwise in their Conceptions.

Now what these Men fancy they know of Women by Reflection, your lewd and vicious Men believe they have learned by Experience.  They have seen the poor Husband so misled by Tricks and Artifices, and in the midst of his Enquiries so lost and bewilder’d in a crooked Intreague, that they still suspect an Under-Plot in every female Action; and especially where they see any Resemblance in the Behaviour of two Persons, are apt to fancy it proceeds from the same Design in both.  These Men therefore bear hard upon the suspected Party, pursue her close through all her Turnings and Windings, and are too well acquainted with the Chace, to be slung off by any false Steps or Doubles:  Besides, their Acquaintance and Conversation has lain wholly among the vicious Part of Womankind, and therefore it is no Wonder they censure all alike, and look upon the whole Sex as a Species of Impostors.  But if, notwithstanding their private Experience, they can get over these Prejudices, and entertain a favourable Opinion of some Women; yet their own loose Desires will stir up new Suspicions from another Side, and make them believe all Men subject to the same Inclinations with themselves.
