Notice.

This book professes to be a compilation, from a considerable number of authors, of those facts and opinions in Intellectual Philosophy, which seemed to the writer most worthy to be received. The authors, who have been chiefly consu'ted, will be found mentioned in the course of the work; and, in some instances, a few remarks have been made on the character of their writings. Locke, Stewart, and Brown have afforded a greater share of the materials than others; Condillac, Beattie, Malebranche, Hume, Reid, Berkeley, &c. I ave been carefully consulted. In a few instances, the statements of these writers have been admitted with only slight variations, when it was thought they had been peculiarly happy in them.

The work sets forth no other pretensions, than what is purported in the title page, viz. as a TEXT-BOOK. As such, it is hoped, it will be found acceptable to instructers and students. A book of this kind, in this important department of science, has been for a long time needed; and the present attempt towards supplying the deficiency is submitted to the candid judgment of the publick.
