Keats mourned that the rainbow, which as a boy had been for him a magic thing, had lost its glory because the physicists had found it resulted merely from the refraction of the sunlight by the raindrops. Yet knowledge of its causation could not spoil the rainbow for me. I am sure that it is not given to man to be omniscient. There will always be something left to know, something to excite the imagination of the poet and those attuned to the great world in which they live (p. 64)
Robert FrostThe Armful For every parcel I stoop down to seize I lose some other off my arms and knees, And the whole pile is slipping, bottles, buns, Extremes too hard to comprehend at. once Yet nothing I should care to leave behind. With all I have to hold with hand and mind And heart, if need be, I will do my best. To keep their building balanced at my breast. I crouch down to prevent them as they fall; Then sit down in the middle of them all. I had to drop the armful in the road And try to stack them in a better load.
Robert Frost
