Behind the complicated details of the world stand the simplicities: God is good, the grown-up man or woman knows the answer to every question, there is such a thing as truth, and justice is as measured and faultless as a clock. Our heroes are simple: they are brave, they tell the truth, they are good swordsmen and they are never in the long run really defeated. That is why no later books satisfy us like those which were read to us in childhood—for those promised a world of great simplicity of which we knew the rules, but the later books are complicated and contradictory with experience; they are formed out of our own disappointing memories.
