of inquiry. 
LOGIC, 
The Science of Logic may conveniently 
be divided into three parts; of these, 
The first part comprehends an In¬ 
vestigation of the Intellectual Forcers of 
l^Ian, 
The second part of Logic embraces, 
the Art of Reasoning, and all the Aux¬ 
iliaries hy which this important Artis 
cultivated and brought to its Maturity. 
The last department of Logic includes 
language—The Philosophy of Grammar 
— Philosophical Criticism — Composi¬ 
tion, 4 'c. 
I. Of the Faculties of the Human Mind. 
Logic being chiefly conversant in the 
use and improvement of our intellectual 
faculties, the nature and history of these 
first claim our attention. 
In investigating the nature of our in¬ 
tellectual powers, they may, perhaps, be 
conveniently arranged in the following 
order; 
1. Of Consciousnessf or that power by 
^hich the mind is enabled to attend to 
its own operations. 
2 Of Personal, or rather, perhaps, 
Mental Identity; that act, viz. of the 
mind, by which it recognises its own 
permanent existence, through a conse¬ 
cutive series of changing sensations, 
3. Of Perception, a, Difference be¬ 
tween sensation and perception—Of 
External Perception in general. Process

tire External Organ of Sense.—Change

this impression.—Perception of external

€. Theory of Perception adopted by mo¬ 
dern philosophers antecedent to the time 
of Mr. Locke.— Descartes, —His doctrine

Deity. Principia Philusophire. — Medi- 
tationes, —Hobbes*— De Natura Homi- 
nis. ■ —IVIalebranche,-—admitted in its 
full extent Descartes’s Doctrine of Se¬ 
condary Causes; but contended that the 
mind does not conceive external ob¬ 
jects, but the ideas of them; considered 
these ideas as existences distinct from 
the sentient or percipient mind. These 
ideas eternally existed in the divine 
mind. — The divine mind, present to 
every other mind, communicates to those 
minds the ideas which eternally existed 
in itself. — De la Recherche de la Verite 
—An excellent book, nocwitl)standing 
the extravagant and untenable Theory of 
Pei^ception unfolded in it j contains
