How is the theme of light regarded in the following excerpt from Heart of Darkness by Joseph Conrad?
"The sun set; the dusk fell on the stream, and lights began to appear along the shore. The Chapman lighthouse, a three-legged thing erect on a mudflat, shone strongly. Lights of ships moved in the fairway - a great stir of lights going up and going down. And farther west on the upper reaches the place of the monstrous town was still marked ominously on the sky, a brooding gloom in sunshine, a lurid glare under the stars." ??
The beauty of power ?
The ugliness of civilization ?
The finish of a sunset ?
None of the above
