do not perceive very distinct marks of the existence of 
this instinct. It probably influences the exertions of 
the social tribes of insects, although their condition pre- 
cludes the possibility of observing the proofs of its ope- 
ration. 
8. Power.—We are fond of exercising controul over all 
the objects which surround us, checking or accelerating 
their motions, modifying their properties, and rendering 
them subservient to our purposes. In accomplishing these 
ends we haye recourse to our bodily strength, and_ to

‘The love of liberty is the offspring of this desire, as well 
as the horror of degradation or slavery. 
Many of the lower animals exhibit this instinct, in their 
hatred of confinement, but more particularly in the resis- 
tance which they offer’ when any individual, even of their 
own species, attempts to impose any restraint, or even to

of the approbation of his master, but appears unwilling that 
his companion should enjoy any share of the favour. 
In man this instinct is cultivated with care, and much 
pains bestowed to extend its influence, in order to secure
