Conrad's depth of wisdom must trouble and terrify those who read him for entertainment. There are few secrets in the mind of men or in the pitiless heart of nature that he has not captured and made his plaything. He calls up all the dreams and illusions by which men have been destroyed and saved, and lays them mockingly naked. He is the master of dreams, the interpreter of illusions, the chronicler of memory. He shows the bare side of every virtue, the hidden heroism of every vice or crime. He calls up before him all the injustices that have come to birth out of ignorance and self-love. He shows how failure is success, and success failure, and that the sinner can be saved. His meanest creatures have in them a touch of honor, of honesty, or of heroism; his heroes have always some error, weakness, a mistake, some sin or crime, to redeem. And in all this there is no judgment, only an implacable comprehension, as of one outside nature, to whom joy and sorrow, right and wrong, savagery and civilization, are equal and indifferent. Reality, to Conrad, is non-existent; he sees through it into a realm of illusion of the unknown: a world that is comforting and bewildering, filled with ghosts and devils, a world of holy terror. Always is there some suggestion of a dark region, within and around one; the consciousness that "They made a whole that had features, shades of expression, a complicated aspect that could be remembered by the eye, and something else besides, something invisible, a directing spirit of perdition that dwells within, like a malevolent soul in a detestable body." "This awful activity of mind" is seen at work on every page, torturing familiar words into strange meanings, clutching at cobwebs, in a continual despair before the unknown. Something must be found, in the most unlikely quarter; a word, a hint, something unsaid but guessed at in a gesture, a change of face. "He turned upon me his eyes suddenly amazed and full of pain, with a bewildered, startled face, as though he had tumbled down from a star." There is a mental crisis in that look: the unknown has suddenly opened.
