Excerpt from Elements of Mental Philosophy: Containing a Critical Exposition of the Principal Phenomena and Powers of the Human Mind The nature of the human mind has not been so fully developed that there remains no demand for farther labor in this departrnent of extensive and elevated science; in re rd to which, it must be con ceded that its utility, its difficulty, an its sublimity are unsurpassed by those of an other science; while it is superior to all others, by embracing, q ifying, and controlling the entire field of rational ideas since the mind is at once the agent and instrument of all investiga tion, and without an accurate knowledge of its powers and modes of operation, we are not competent in any of its fields of inquiry, to conduct its processes to the greatest advantage, or prosecute them to their most useful and sublime results.
