Do you see, Arren, how an act is not, as young men think, like a rock that one picks up and throws, and it hits or misses, and that's the end of it. When that rock is lifted, the earth is lighter; the hand that bears it is heavier. When it is thrown, the circuits of the stars respond, and where it strikes or falls the universe is changed.
