And tho' these two causes are often confounded, (for they require some distinguishing;) yet, as they proceed from very different motives, so they are as clearly distinct in their operations: for indeed, the affectation which arises from vanity is nearer to truth than the other; as it hath not that violent repugnancy of nature to struggle with, which that of the hypocrite hath.

It may be likewise noted, that affectation doth not imply an absolute negation of those qualities which are affected: and therefore, tho', when it proceeds from hypocrisy, it be nearly allied to deceit; yet when it comes from vanity only, it partakes of the nature of ostentation: for instance, the affectation of liberality in a vain man, differs visibly from the same affectation in the avaricious; for tho' the vain man is not what he would appear, or hath not the virtue he affects, to the degree he would be thought to have it; yet it sits less awkwardly on him than on the avaricious man, who is the very reverse of what he would seem to be.
From the discovery of this affectation arises the Ridiculous--which always strikes the reader with surprize and pleasure; and that in a higher and stronger degree when the affectation arises from hypocrisy, than when from vanity: for to discover any one to be the exact reverse of what he affects, is more surprizing, and consequently more ridiculous, than to find him a little deficient in the quality he desires the reputation of.

I might observe that our Ben Jonson, who of all men understood the Ridiculous the best, hath chiefly used the hypocritical affectation.
Now from affectation only, the misfortunes and calamities of life, or the imperfections of nature, may become the objects of ridicule.
Surely he hath a very ill-framed mind, who can look on ugliness, infirmity, or poverty, as ridiculous in themselves: nor do I believe any man living who meets a dirty fellow riding through the streets in a cart, is struck with an idea of the Ridiculous from it; but if he should see the same figure descend from his coach and six, or bolt from his chair with his hat under his arm, he would then begin to laugh, and with justice.

In the same manner, were we to enter a poor house and behold a wretched family shivering with cold and languishing with hunger, it would not incline us to laughter, (at least we must have very diabolical natures, if it would): but should we discover there a grate, instead of coals, adorned with flowers, empty plate or china dishes on the side-board, or any other affectation of riches and finery either on their persons or in their furniture: we might then indeed be excused, for ridiculing so fantastical an appearance.
Much less are natural imperfections the object of derision: but when ugliness aims at the applause of beauty, or lameness endeavours to display agility; it is then that these unfortunate circumstances, which at first moved our compassion, tend only to raise our mirth.
The poet carries this very far; None are for being what they are in fault, But for not being what they would be thought.
Where if the metre would suffer the word Ridiculous to close the first line, the thought would be rather more proper.

Great vices are the proper objects of our detestation, smaller faults of our pity: but affectation appears to me the only true source of the Ridiculous.
But perhaps it may be objected to me, that I have against my own rules introduced vices, and of a very black kind into this work.
