By the fame common Denomination, it feems 
almoft of a different Nature. If, after this, 
we look into the feyeral inward Perfections 
of Cunning and Sagacity, or what we gene¬ 
rally call InftinCt, we find them rifing in the 
fame Manner, imperceptibly, one above 
another, and receiving additional Improve¬ 
ments according to the Species in which 
they are implanted. 
This Progrefs in Nature is fo very gradual, 
that the whole Chafm, from a Plant to a 
Man, is filled up with divers Kinds of Crea¬ 
tures, rifing one over another by fuch a gen¬ 
tle and eafy Afcent, that the littleTranfitions 
and Deviations from one Species to another 
are almofl infenfible. And the intermediate 
Space is fo well hufbanded and managed, 
that there is fcarce a Degree of Perception 
which does not appear in fome one Part of 
the World of Life. Since then the Scale of 
Being advances by fuch regular Steps fo high 
as Man, we may by Parity of Reafon fup- 
pofe, that it hill proceeds gradually upwards 
thro’ numberlefs Orders of Beings of a fupe- 
rior Nature to him : as there is an infinitely 
greater Space and Room for different Degrees 
of Perfection between the Supreme Being 
and Man, than between Man and the mod 
defpicable Infect.” 
Mr. Locke’s Thoughts upon this Subject 
are very curious; <£ That there fhould”, fays 
he.
