It seems to be right that some attempt should be made to describe the character and strength of the author's intellect, and the method of its operations; and to give a view of the fundamental characteristic principles by which he professes to distinguish his own philosophy from that of other writers on metaphysical subjects. An attempt should also be made to tell in what respect Hume has made incidental suggestions which have either been admitted as new truths in metaphysics, or have, as original but perhaps fallacious suggestions, afforded to other thinkers the means of establishing truths. These being the general objects to be kept in view, there is no intention to take them in any precise order, or to exhaust them in remarks on this one work. To attempt an analysis of the work would be out of place. There can be no more repulsive matter for reading than condensed metaphysics; and probably there is nothing less instructive than those abridgments, which, necessarily suppressing the author's discursive arguments, appeal almost entirely to the memory. To seize on and give a descriptive rather than an analytical account of the prominent features of the system, will be the chief aim of these remarks. Moreover, the Treatise bears on subjects which are nearly all recalled in its author's subsequent works; and while there are some things in the critical history of Hume's opinions which may be appropriately viewed in connexion with his first publication, there are others which it may be more expedient to examine when he is found reconsidering the subjects in his later works; and again, others which may be viewed in a general attempt to describe the extent of his literary achievements.
