| The first excerpt represents the element of Air. It speaks of mental influences and the process of thought, and is drawn from Reason Discourse by Rene Descartes: in the world and farther, by considering the concatenation of these laws,
it appears to me that I have discovered many truths more useful and more
important than all I had before learned, or even had expected to learn.
But because I have essayed to expound the chief of these discoveries in a
treatise which certain considerations prevent me from publishing, I cannot
make the results known more conveniently than by here giving a summary of
the contents of this treatise. It was my design to comprise in it all
that, before I set myself to write it, I thought I knew of the nature of
material objects. But like the painters who, finding themselves unable to
represent equally well on a plain surface all the different faces of a
solid body, select one of the chief, on which alone they make the light

The second excerpt represents the element of Fire. It speaks of emotional influences and base passions, and is drawn from The Prince by Nicolo Machiavelli: organized and drilled, to follow incessantly the chase, by which he
accustoms his body to hardships, and learns something of the nature of
localities, and gets to find out how the mountains rise, how the
valleys open out, how the plains lie, and to understand the nature of
rivers and marshes, and in all this to take the greatest care. Which
knowledge is useful in two ways. Firstly, he learns to know his
country, and is better able to undertake its defence; afterwards, by
means of the knowledge and observation of that locality, he
understands with ease any other which it may be necessary for him to
study hereafter; because the hills, valleys, and plains, and rivers
and marshes that are, for instance, in Tuscany, have a certain

| The third excerpt represents the element of Water. It speaks of pure spiritual influences and feelings of love, and is drawn from On the Origin of Species by Charles Darwin: race, are found nearly uniform, they are considered as highly serviceable
in classification; but in some groups of animals all these, the most
important vital organs, are found to offer characters of quite subordinate
value.
We can see why characters derived from the embryo should be of equal
importance with those derived from the adult, for our classifications of
course include all ages of each species. But it is by no means obvious, on
the ordinary view, why the structure of the embryo should be more important
for this purpose than that of the adult, which alone plays its full part in
the economy of nature. Yet it has been strongly urged by those great
naturalists, Milne Edwards and Agassiz, that embryonic characters are the

The fourth excerpt represents the element of Earth. It speaks of physical influences and the impact of the unseen on the visible world, and is drawn from A Pair of Blue Eyes by Thomas Hardy: of him and turned to Knight; but he did not like to advance the
statement now, or even to think the thought. To fancy otherwise
accorded better with the hope to which Knight's estrangement had
given birth: that love for his friend was not the direct cause,
but a result of her suspension of love for himself.
'Such a matter must not be allowed to breed discord between us,'
Knight returned, relapsing into a manner which concealed all his
true feeling, as if confidence now was intolerable. 'I do see
that your reticence towards me in the vault may have been dictated
by prudential considerations.' He concluded artificially, 'It was
a strange thing altogether; but not of much importance, I suppose,
