Farrar, Straus, & Giroux: 1969. Fourth printing. Hardcover in a price-clipped jacket. Very good.
"Think of the sheer multiplication of works of art available to every one of us, superadded to the conflicting tastes and odors and sights of the urban environment that bombard our senses. Ours is a culture based on excess, on overproduction; the result is a steady loss of sharpness in our sensory experience. All the conditions of modern life — its material plenitude, its sheer crowdedness — conjoin to dull our sensory faculties. And it is in the light of the condition of our senses, our capacities (rather than those of another age), that the task of the critic must be assessed.
What is important now is to recover our senses. We must learn to see more, to hear more, to feel more."
