When you present a poem or a picture to a man possessed of this talent, the delicacy of his feeling makes him be sensibly touched with every part of it; nor are the masterly strokes perceived with more exquisite relish and satisfaction, than the negligences or absurdities with disgust and uneasiness. A polite and judicious conversation affords him the highest entertainment; rudeness or impertinence is as great a punishment to him. In short, delicacy of taste has the same effect as delicacy of passion: It enlarges the sphere both of our happiness and misery, and makes us sensible to pains as well as pleasures, which escape the rest of mankind.
I believe, however, every one will agree with me, that, notwithstanding this resemblance, delicacy of taste is as much to be desired and cultivated as delicacy of passion is to be lamented, and to be remedied, if possible. The good or ill accidents of life are very little at our disposal; but we are pretty much masters what books we shall read, what diversions we shall partake of, and what company we shall keep.
[David Hume, "Of the Delicacy of Taste and Passion", par. 2-3.]
