「凝望無底洞的時候,無底洞也在凝望你。(If you gaze for long into an abyss, the abyss gazes also into you.)」
以《無底洞》一片視之,這句話沒有什麼問題;但事實上柯麥隆在尼采的話裡頭只挖出這一段來,不免有點兒斷章取義的味道。因為若要完整地明白原意,重點其實在柯麥隆沒有引用的前一句話;這段文字,完整看來應是如此:「對抗怪物的人,應當心別讓自己也成為怪物。倘若你凝望深淵的時間夠長,深淵也會凝望你。(He who fights with monsters might take care lest he thereby become a monster. And if you gaze for long into an abyss, the abyss gazes also into you.)」
