| The first excerpt represents the element of Air. It speaks of mental influences and the process of thought, and is drawn from Poems of William Blake by William Blake: The Cloud reclind upon his airy throne and answerd thus.
Then if thou art the food of worms, O virgin of the skies,
How great thy use, how great thy blessing, every thing that lives.
Lives not alone nor or itself: fear not and I will call,
The weak worm from its lowly bed, and thou shalt hear its voice.
Come forth worm and the silent valley, to thy pensive queen.
The helpless worm arose and sat upon the Lillys leaf,
And the bright Cloud saild on, to find his partner in the vale.
III.
Then Thel astonish'd view'd the Worm upon its dewy bed.
Art thou a Worm? image of weakness. art thou but a Worm?

The second excerpt represents the element of Fire. It speaks of emotional influences and base passions, and is drawn from On the Origin of Species by Charles Darwin: intermediate between existing forms; but are intermediate only by a long
and circuitous course through many extinct and very different forms. We
can clearly see why the organic remains of closely consecutive formations
are more closely allied to each other, than are those of remote formations;
for the forms are more closely linked together by generation: we can
clearly see why the remains of an intermediate formation are intermediate
in character.
The inhabitants of each successive period in the world's history have
beaten their predecessors in the race for life, and are, in so far, higher
in the scale of nature; and this may account for that vague yet ill-defined
sentiment, felt by many palaeontologists, that organisation on the whole
