“The earth seemed unearthly. We are accustomed to look upon the shackled form of a conquered monster, but there — there you could look at a thing monstrous and free. It was unearthly, and the men were — No, they were not inhuman. Well, you know, that was the worst of it — this suspicion of their not being inhuman. It would come slowly to one. They howled and leaped, and spun, and made horrid faces; but what thrilled you was just the thought of their humanity — like yours — the thought of your remote kinship with this wild and passionate uproar. Ugly. Yes, it was ugly enough; but if you were man enough you would admit to yourself that there was in you just the faintest trace of a response to the terrible frankness of that noise, a dim suspicion of there being a meaning in it which you — you so remote from the night of the first ages — could comprehend.” (44)
Heart of Darkness, Joseph Conrad
