He sat down and collected his thoughts. They were quite easy to collect, because there weren't very many of them, and they all concerned the same sub… - Philip Pullman

Occasionally they would hear a harsh croak or a splash as some amphibian was disturbed, but the only creature they saw was a toad as big as Will's foot, which could only flop in a pain-filled sideways heave as if it were horribly injured. It lay across the path, trying to move out of the way and looking at them as if it knew they meant to hurt it.
'It would be merciful to kill it,' said Tialys.
'How do you know?' said Lyra. 'It might still like being alive, in spite of everything.'
'If we killed it, we'd be taking it with us,' said Will. 'It wants to stay here. I've killed enough living things. Even a filthy stagnant pool might be better than being dead.'
'But if it's in pain?' said Tialys.
'If it could tell us, we'd know. But since it can't, I'm not going to kill it. That would be considering our feelings rather than the toad's.'
They moved on.

You are so young, Lyra, too young to understand this, but I shall tell you anyway and you'll understand it later: men pass in front of our eyes like butterflies, creatures of a brief season. We love them; they are brave, proud, beautiful, clever; and they die almost at once. They die so soon that our hearts are continually racked with pain. We bear their children, who are witches if they are female, human if not; and then in the blink of an eye they are gone, felled, slain, lost. Our sons, too. When a little boy is growing, he thinks he is immortal. His mother knows he isn't. Each time becomes more painful, until finally your heart is broken. Perhaps that is when Yambe-Akka comes for you. She is older than the tundra. Perhaps, for her, witches' lives are as brief as men's are to us.

Religion begins in story. Yes, it does, because religion is an attempt to make sense of what is incomprehensible to us, what is inexplicable, what is awe-inspiring, what is frightening, what moves us to great wonder, and so on. That is the religious impulse, and it is part of our psychological makeup — of everyone's psychological makeup.
