“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 shape, and gives to airy nothing a local habitation and a name; such tricks hath strong imagination.”

“The lunatic, the lover, and the poetAre 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 forthThe forms of things unknown, the poet's penTurns them to shapes and gives to airy nothingA local habitation and a name.”

“Lovers and madmen have such seething brains,Such shaping fantasies, that apprehendMore than cool reason ever comprehends.The lunatic, the lover and the poetAre 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 fine frenzy rolling,Doth glance from heaven to earth, from earth to heaven;And as imagination bodies forthThe forms of things unknown, the poet's penTurns them to shapes and gives to airy nothingA local habitation and a name.”

“I am very proud, revengeful, ambitious, with more offences at my beck than I have thoughts to put them in, imagination to give them shape, or time to act them in. What should such fellows as I do crawling between earth and heaven? We are arrant knaves, all. Believe none of us.”

“The Brightness of her cheek would shame those stars as daylight doth a lamp; her eyes in heaven would through the airy region stream so bright that birds would sing, and think it were not night.”

“There are more things in Heaven and Earth, Horatio, than are dreamt of in your philosophy.”

“O, mickle is the powerful grace that liesIn herbs, plants, stones, and their true qualities:For nought so vile that on the earth doth liveBut to the earth some special good doth give,Nor aught so good but strain’d from that fair useRevolts from true birth, stumbling on abuse:Virtue itself turns vice, being misapplied;And vice sometimes by action dignified.Within the infant rind of this small flowerPoison hath residence and medicine power:For this, being smelt, with that part cheers each part;Being tasted, slays all senses with the heart.Two such opposed kings encamp them stillIn man as well as herbs, grace and rude will;And where the worser is predominant,Full soon the canker death eats up that plant.”
