FACULTIES OF THE MIND. 995 
scarcely be perceived, unless in actions which suppose a 
succession of events similar to those which have occurred. 
There is one very striking difference between this facul- 
ty, as it exists in man and in the lower animals. With us, 
it is frequently exerted on speculative truths: In them, 
on present or future sensations. With us, sometimes on 
things which we know will never happen: With them, on 
things which the probabilities of experience warrant. 
Il. Ipgas or REFLECTION. 
The knowledge which we obtain through the medium of 
our senses, by means of the three faculties whose nature 
we have been attempting to illustrate, is denomimated Ex- 
perience. In acquiring it, the mind employs the senses to 
collect, the attention to fix, the memory to recall, and the 
imagination to combine, the various impressions which ex- 
ternal objects make upon us. In the course of this very 
complicated process, the mind, by degrees, perceives rela- 
tions among external objects which were not discovered 
immediately after the first impressions, and obtains results, 
from an attention to the intellectual process, by which the 
limits of our enjoyment and power are extended, and the 
senses directed to proper objects of examination. In con- 
sequence of this habitual or occasional attention, we acquire 
a number of ideas, which do not resemble those which have 
been formed directly from the impressions of the senses. 
These are, therefore, properly termed Secondary Ideas, or 
Ideas of Reftection. Yn the formation of these ideas, the 
imagination exercises the greatest influence. They, in- 
deed, arise from the unceasing combinations and decompo- 
sitions of this faculty, and might, with propriety, be termed 
Ideas of the Imagination. We may likewise observe, that 
while they depend upon the condition of the primary im- 
pressions, and are subordinate to these, they are still ise.
