" 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. "

" The Earth Speaks, clearly, distinctly, and, in many of the realms of Nature, loudly, to William Jennings Bryan, but he fails to hear a single sound. The earth speaks from the remotest periods in its wonderful life history in the Archaeozoic Age, when it reveals only a few tissues of its primitive plants. Fifty million years ago it begins to speak as 'the waters bring forth abundantly the moving creatures that hath life.' In successive eons of time the various kinds of animals leave their remains in the rocks which compose the deeper layers of the earth, and when the rocks are laid bare by wind, frost, and storm we find wondrous lines of ascent invariably following the principles of creative evolution, whereby the simpler and more lowly forms always precede the higher and more specialized forms.
The earth speaks not of a succession of distinct creations but of a continuous ascent, in which, as the millions of years roll by, increasing perfection of structure and beauty of form are found; out of the water-breathing fish arises the air-breathing amphibian; out of the land-living amphibian arises the land-living, air-breathing reptile, these two kinds of creeping things resembling each other closely. The earth speaks loudly and clearly of the ascent of the bird from one kind of reptile and of the mammal from another kind of reptile. "
