and therefore never can be sources of science truly so called.

Of this, however, the man of experiment appears to be totally ignorant,
and in consequence of this, he is likewise ignorant that parts can only
be truly known through wholes, and that this is particularly the case
with parts when they belong to a whole, which, as we have already
observed, from comprehending in itself the parts which it produces, is
called a whole prior to parts. As he, therefore, would by no means merit
the appellation of a physician who should attempt to cure any part of the
human body, without a previous knowledge of the whole; so neither can he
know any thing truly of the vegetable life of plants, who has not a
previous knowledge of that vegetable life which subsists in the earth as
a whole prior to, because the principle and cause of all partial
vegetable life, and who still prior to this has not a knowledge of that
greater whole of this kind which subsists in nature herself; nor, as
Hippocrates justly observes, can he know any thing truly of the nature of
the human body who is ignorant what nature is considered as a great
comprehending whole. And if this be true, and it is so most indubitably,
with all physiological inquiries, how much more must it be the case with
respect to a knowledge of those incorporeal forms to which we ascended in
the first part of this Introduction, and which in consequence of
proceeding from wholes entirely exempt from body are participated by it,
with much greater obscurity and imperfection? Here then is the great
difference, and a mighty one it is, between the knowledge gained by the
most elaborate experiments, and that acquired by scientific reasoning,
founded on the spontaneous, unperverted, and self-luminous conceptions of
the soul. The former does not even lead its votary up to that one nature
of the earth from which the natures of all the animals and plants on its
surface, and of all the minerals and metals in its interior parts,
blossom as from a perennial root. The latter conducts its votary through
