“ Insect Life.” 293 
To what conclusion then are we to come? It is, that all the 
phenomena of insect life are referable to instinct, which is held 
to be synonymous with vitality,—‘ instinctive and vital acts being 
but different manifestations of life, executed in accordance with 
the pre-established harmony between the creature and the ex- 
ternal world.” 
I do not now propose to examine the physiological doctrines 
propounded in this book; I only contend that the facts of insect 
life do not bear out the theory. For in insects we see organs 
analogous to the organs of the senses of the higher animals, and 
perceive actions performed, which, if proceeding from the higher 
animals, we should at once acknowledge as conclusive proof of 
sensation; and I do not think that we are warranted in assuming 
that such creatures as insects are destitute of sensation, because 
we cannot trace a complete identity with the higher animals in the 
structure and functions of their organs or their nervous system ; 
nor in disputing the possession of a faculty (such as hearing) when 
we see its manifestation, because we do not know the organ by 
which it accomplished its purpose.
