570 페이지 - We accordingly believe that poetry, far from injuring society, is one of the great instruments of its refinement and exaltation. It lifts the mind above ordinary life, gives it a respite from depressing cares, and awakens the consciousness of its affinity with what is pure and noble.
394 페이지 - Yon cottager, who weaves at her own door, Pillow and bobbins all her little store: Content though mean, and cheerful if not gay, Shuffling her threads about the livelong day, Just earns a scanty pittance, and at night Lies down secure, her heart and pocket light...
479 페이지 - Every thing that heard him play, Even the billows of the sea, Hung their heads, and then lay by. In sweet music is such art, Killing care and grief of heart Fall asleep, or hearing die.
570 페이지 - ... with what is pure and noble. In its legitimate and highest efforts, it has the same tendency and aim with Christianity ; that is, to spiritualize our nature.

495 페이지 - When we mean to build, We first survey the plot, then draw the model ; And when we see the figure of the house, Then must we rate the cost of the erection ; Which if we find outweighs ability, What do we then but draw anew the model In fewer offices, or at least desist To build at all...

570 페이지 - The lunatic, the lover, and the poet Are of imagination all compact; One sees more devils than vast hell can hold, That is, the madman; the lover, all as frantic, Sees Helen's beauty in a brow of Egypt; The poet's eye, in a fine frenzy rolling, Doth glance from heaven to earth, from earth to heaven; And as imagination bodies forth The forms of things unknown, the poet's pen Turns them to shapes, and gives to airy nothing A local habitation and a name.
