Their immediate sensation, to the person possessed of them, is agreeable.

Others enter into the same humour, and catch the sentiment, by a contagion or natural sympathy; and as we cannot forbear loving whatever pleases, a kindly emotion arises towards the person who communicates so much satisfaction.
He is a more animating spectacle; his presence diffuses over us more serene complacency and enjoyment; our imagination, entering into his feelings and disposition, is affected in a more agreeable manner than if a melancholy, dejected, sullen, anxious temper were presented to us.
Hence the affection and probation which attend the former: the aversion and disgust with which we regard the latter.
[Footnote: There is no man, who, on particular occasions, is not affected with all the disagreeable passions, fear, anger, dejection, grief, melancholy, anxiety, &c.

But these, so far as they are natural, and universal, make no difference between one man and another, and can never be the object of blame.

It is only when the disposition gives a PROPENSITY to any of these disagreeable passions, that they disfigure the character, and by giving uneasiness, convey the sentiment of disapprobation to the spectator.] Few men would envy the character which Caesar gives of Cassius: He loves no play, As thou do'st, Anthony: he hears no music: Seldom he smiles; and smiles in such a sort, As if he mock'd himself, and scorn'd his spirit That could be mov'd to smile at any thing.
Not only such men, as Caesar adds, are commonly DANGEROUS, but also, having little enjoyment within themselves, they can never become agreeable to others, or contribute to social entertainment.

In all polite nations and ages, a relish for pleasure, if accompanied with temperance and decency, is esteemed a considerable merit, even in the greatest men; and becomes still more requisite in those of inferior rank and character.
