A superficial Knowledge of human Nature, will never qualify a Man to be a Writer of Characters. He must be a Master of the Science; and be able to lead a Reader, knowingly, thro’ that Labyrinth of the Passions, which fill the Heart of Man, and make him either a noble or a despicable Creature. For tho’ some, who have never attempted any thing of this kind, may think it an easy Matter to write two or three Pages of Morality with Spirit, to describe an Action, a Passion, a Manner; yet had they made the Experiment, the Event wou’d not have answer’d their Expectation, and they wou’d have found, that this easy Work was more difficult than they, at first, imagin’d.

The Features of every single Passion must be known; the Relation which that Passion bears to another, must be discover’d; and the Harmony and Discord which result from them must be felt. Many have studied these Things, but few have thoroughly understood them. The Labour is vast; ’tis almost infinite; and yet without a Knowledge of these Things, ’twill be impossible ever to draw a Character so to the Life, as that it shall hit one Person, and him only.

We have all of us different Souls, and our Souls have Affections as different from one another, as our outward Faces are in their Lineaments. Each Man contains a little World within himself, and every Heart is a new World. We cannot therefore attain to a perfect Knowledge of human Nature, by studying others or our selves alone, but by studying both. ’Tis this Knowledge which sets the Philosopher above the Peasant, and gives the Preference to one Author above another. This Knowledge has a Force, something like to that of Magic Charms: by the help of it one, who is Master of the Science, can turn Men inside outwards, and expose them to the Eyes of the World, as they really are, and not as they wou’d fain appear to be. By the help of this Knowledge an intelligent Writer can form to his Reader the most agreeable, most instructive Entertainment that can possibly be desir’d; transport him, with the greatest Ease imaginable, from the Solitude of his Chamber to Places of the greatest Concourse; there to see and learn the Virtues of Men; there to see and shun their Vices, without any danger of being corrupted by the Contagion of a real Commerce.

How absolutely necessary a thorough Insight into the Heart and Passions of Man is to a Writer of Characters, will be more evident by descending to some Particulars, and pointing out some of those nice Circumstances, which a Writer of Characters must accurately observe, and by which his Capacity in this Way may be easily judg’d of.

It must be observ’d then, that the Heart of Man is frequently actuated by more Passions than one: And as the same Object does, by its different Position, afford to the Spectator different Representations, so does the same Affection of the Mind, by exerting it self after a different manner, lay a real Foundation for so many distinct Characters. The under Passions may, by their various Operations, cause some Diversity in the Colour and Complexion of the Whole, but ’tis the Master-Passion which must determine the Character.

Since therefore the under Parts of a Character are not essential, they may or may not be reciprocal. A covetous Man may be impudent, or he may have some share of Modesty left: On the other Hand, an impudent Man may be generous, or his Character may be stain’d by Avarice. And therefore to make the Features of one Virtue or Vice enter, as under Parts, into the Character of another Virtue or Vice, is so far from being a Transgression of the Nature of Things, that, on the contrary, all the Beauty of Characteristic-Writing, and all the Beauty which arises from the Variety of an agreeable Mixture, entirely depends on this. The main Difficulty consists in making the Master-Passion operate so conspicuously throughout the Whole, as that the Reader may, in every step of the Performance, immediately discover it.

The Truth of it is, that there are some Affections of the Mind, which not only constitute of themselves a distinct Virtue or Vice, but are also the Foundation of many others. Avarice is of this extensive Nature; it constitutes, of it self, a distinct Character, and it enters into the Competition of several others. St. Paul says, that the love of money is the root of all evil; which Maxim the spurious Phocylides has express’d in the following Verse,

Ἡ φιλοχρημοσύνη μήτηρ κακότητος ἁπάσης.

This Doctrine may be made yet more sensible by applying it to the Practice of Theophrastus, whose Conduct, in this Respect, ought to be look’d upon as an authentick Pattern. Rusticity, Avarice and Impudence, are in their own Nature distinct Vices, but yet there is a very near Relation between them, which has a real Foundation in the Actions of Men. And, as on the one Hand, Theophrastus has drawn distinct Characters of these Vices, so, on the other Hand, he has made the peculiar Features of one or more of these Vices enter into the Characters of the other. This is Matter of Fact; and if the Reader will be at the Pains to compare the 6th, 9th, and 11th, Chapters, as he will be perswaded of the Truth of what is here asserted, so will he be convinc’d, at the same Time, that Theophrastus has not confounded by this Mixture the real Nature of Things, or transgress’d thereby, in any wise, the Rules of Characteristic-Justice.

Again; Loquacity and an ill-tim’d Behaviour are two very different Vices in common Conversation; but yet Theophrastus has concluded his Character of Loquacity, with the same Stroke which begins that of an ill-tim’d Behaviour; because tho’ these Vices are of a different Nature, yet do they not exclude each other; and the Actions of Men manifestly prove, that they are frequently to be found in the same Subject.
