y so much the farther
it is distant from having any contrary to it, and its Life is the more
perfect. Now since that Animal Spirit which is seated in the Heart is of
a most exact Temperature, as being finer than _Earth_ and _Water_, and
grosser than _Fire_ and _Air_, it has the Nature of a Mean between them
all, and which has no manifest Opposition to any of the Elements, and by
this means is fitted to become that Form which constitutes an Animal.
And he saw that it follow'd from hence, that those _Animal Spirits_
which were of the most even Temperature, were the best dispos'd for the
most perfect Life in this World, of Generation and Corruption, and that
this Spirit was very near having no opposite to its Forms, and did in
this respect resemble the Heavenly Bodies which have no opposite to
their Forms; and was therefore the Spirit of the Animal, because it was
a Mean between all the Elements, and had no absolute Tendency, either
upwards or downwards; but that, if it were possible it should be plac'd
in the middle Space, between the Center and the highest Bounds of the
Region of Fire, and not be destroy'd, it would continue in the same

if it mov'd in its place, it would be round its own Center, and that it
was impossible for it to be of any other Figure but Spherical, and for
that reason it is very much like to the Heavenly Bodies.
Sec. 71. And when he had consider'd the Properties of Animals, and could
not see any one among them, concerning which he could in the least
suspect that it had any Knowledge of this _necessarily self-existent
Being_; but he knew that his own Essence had the Knowledge of it: He
concluded from hence that he was an Animal, endu'd with a Spirit of an
equal Temperature, as all the Heavenly Bodies are, and that he was of a
distinct Species from the rest of Animals, and that he was created for
another end, and design'd for something greater than what they were
capable of. And this was enough to satisfie him of the Nobility of his
Nature; namely, that his viler Part, _i.e._ the Corporeal, was most like
of all to the Heavenly Substances, which are without this World of
Generation and Corruption, and free from all accidents that cause any
Defect, Change or Alteration: And that his noble Part, _viz._, that by
which he attain'd the Knowledge of the _necessarily self-e
