Famous quotes containing the words sound and/or image:
“Wild as it was, it was hard for me to get rid of the associations of the settlements. Any steady and monotonous sound, to which I did not distinctly attend, passed for a sound of human industry.... Our minds anywhere, when left to themselves, are always thus busily drawing conclusions from false premises.”

“The essence of the physicality of the most famous blonde in the world is a wholesome eroticism blurred a little round the edges by the fact she is not quite sure what eroticism is. This gives her her tentative luminosity and what makes her, somehow, always more like her own image in the mirror than she is like herself.”
—Angela Carter (1940–1992)
