If knowledge hath these spiritual uses,--and what reflecting man can doubt the fact, how mortifying is it to see many wasting their strength and throwing away the means by which they could attain these ends, for the sake of wealth and earthly honors. As the alchemist who, in his eager search after the grand magisterium, neglects many discoveries really useful which were within his reach, so these men put their frail trust in the world and waste their lives in the vain pursuit of its phantoms. But we do not expect these men to take this view of the subject unless they have trained their minds to it, either through the christian philosophy, or what is second to that system only, the school of the Platonist writers. It is for this reason chiefly, that we have ventured to recommend the study of the writings of the genius so nearly divine, of that author whose psychological system presaged the christian revelation, as the morning twilight betokens the coming sun. It was his, that beautiful conception of the spirit of the universe, at once so poetical and sublime;--an idea which Abraham Tucker only of modern English writers, seems to have fully comprehended and explained. This sublime and philosophical poet perceived that by an attentive study of nature, the human mind was capable of entering into communion with the divine mind through its works; he felt that he was capable of conceiving more and more of the ideas which existed in the creative mind, as he understood more of the system of the universe; he meditated upon the harmony which extended through the greatest and the least of nature's operations; his soul took in forms of beauty and filled with lofty conceptions until it became enamored of its contemplations, and in the spirit of true poetry he endowed the universe with a soul which governed it and with which the mind of man may commune. But to return to our original proposition; we asserted that the writings of ancient philosophers afforded the best views of psychology to which we have access. By psychology, we mean what relates to our spiritual being. To maintain this proposition it will be necessary to recur, for a moment, to the subject of inquiry which engaged their attention, and to the spirit of those times.
