Presumably one starts with the hope—if not the belief—that Golding's thesis [in Lord of the Flies] is wrong, that finally man is more than a beast…. [But] it becomes clear how unsure Golding is of that thesis and of his ability to make his fable suggest it. He thinks he would be unable (or he knows we would be unwilling) to move from the terms of one to those of the other and so he continually makes the jump for us. Thus Ralph and Jack become, he tells us, "two continents of experience and feeling, unable to communicate" and are later opposed as "the brilliant world of hunting, tactics, fierce exhilaration, skill" and the "world of longing and baffled commonsense."… At one point Simon tries "to express man's essential illness," and the eyes of the pig's head into which he gazes are "dim with the infinite cynicism of adult life"; at another point Sam and Eric protest, Golding says, "out of the heart of civilization." And on the final page, as is well known, the cause of Ralph's tears is supposed to be "the end of innocence, the darkness of man's heart." It is as if Aesop had told us that the fox really liked grapes but was calling them sour because he was unable to reach them.
But Aesop was clear about the separation of his fable and his moral, and consequently so are we. He does not expect the fox's hunger pains to upset us; we can go on to join him in his conclusions about man's rationalizations. But we do care about children's hunger pains and about bullying, and realizing this, Golding is quick to name our concern as one for "mankind's essential illness." He does not trust us to move from the terms of one to those of the other, so he forces children into moral positions and attitudes they could never take and that he could not come out and make explicit in the novel itself.
