THE HE object of this treatise is to give a full and systematic account of two principal
divisions of the science of mind,-the Senses and the Intellect. The remaining two divisions,
comprising the Emotions and the Will, will be the subject of a future treatise. While
endeavouring to present in a methodical form all the important facts and doctrines bearing
upon mind, considered as a branch of science, I have seen reason to adopt some new
views, and to depart, in a few instances, from the most usual arrangement of the topics.
