As to its efficient Cause; Wit owes its Production to an extraordinary and peculiar Temperament in the Constitution of the Possessors of it, in which is found a Concurrence of regular and exalted Ferments, and an Affluence of Animal Spirits refin'd and rectify'd to a great degree of Purity; whence being endow'd with Vivacity, Brightness and Celerity, as well in their Reflexions as direct Motions, they become proper Instruments for the sprightly Operations of the Mind; by which means the Imagination can with great Facility range, the wide Field of Nature, contemplate an infinite Variety of Objects, and by observing the Similitude and Disagreement of their several Qualities, single out and abstract, and then suit and unite those Ideas, which will best serve its purpose. Hence beautiful Allusions, surprizing Metaphors and admirable Sentiments are always ready at hand: And while the Fancy is full of Images collected from innumerable Objects and their different Qualities, Relations and Habitudes, it can at pleasure dress a common Notion in a strange, but becoming Garb; by which, as before observ'd, the same Thought will appear a new one, to the great Delight and Wonder of the Hearer. What we call Genius results from this particular happy Complexion in the first Formation of the Person that enjoys it, and is Nature's Gift, but diversify'd by various specifick Characters and Limitations, as its active Fire is blended and allay'd by different Proportions of Phlegm, or reduc'd and regulated by the Contrast of opposite Ferments. Therefore as there happens in the Composition of a facetious Genius a greater or less, tho still an inferior degree of Judgment and Prudence, and different Kinds of Instincts and Passions, one Man of Wit will be vary'd and distinguish'd from another. That Distinction that seems common to Persons of this Denomination, is an inferior Degree of Wisdom and Discretion; and tho these two Qualities, Wit and Discretion, are almost incapable of a friendly Agreement, and will not, but with great Difficulty, be work'd together and incorporated in the Constitution of any Individual; yet this Observation is not so conspicuous in any, as in those, whose native Complexion comes the nearest to a Subversion and Absence of Mind, tho it should never degenerate into that distemper'd Elevation of the Spirits: Nothing is more common, than to see Persons of this Class always Think Right, and always Act Wrong; admirable for the richness, delicacy, and brightness of their Imaginations, and at the same Time to be pity'd for their want of Prudence and common Sense; abounding with excellent Maxims and instructive Sentiments, which however are not of the least Use to themselves in the Conduct of their Lives. And hence it is certain, that tho the Gentlemen of a pleasant and witty Turn of Mind often make the industrious Merchant, and grave Persons of all Professions, the Subjects of their Raillery, and expose them as stupid Creatures, not
