thodical and reputable in their performance; and a knowledge of the principles on which, in this volume, the art of Logic is founded, can scarcely fail to facilitate the progress of youth in becoming good reasoners. Of this they may be assured, if they have sufficient candour to admit there is such a thing as good reasoning, that there is no accomplishment or qualification any man can acquire more important, than the art of reasoning well. Whether then, youth shall become, in life, men of speculation or men of business, in every step they take, their rational faculties must be constantly exercised; and the subject of which we now speak is calculated entirely to render 'them expert and successful in that exercise. The FIFTH BOOK which offers a sketch of "The Philoso phy of Human Knowledge," seemed a necessary Appendix to the volume; but it was not my object, in the compass of a few pages, to enter upon a subject which I intend to publish in a separate work, as a sequel to my Grammars of Rhetoric and Logic. And, for the purpose of initiating youth in the doctrines of the Philosophy of Mind, I have constructed, on this Grammar of Logic, a Book of "Questions and Exercises," with a "Key" to the same; as, in my humble judgment, no discipline is more successful in accomplishing its end, than that which reduces literature, philosophy, and science, to interlocutory discourse, conducted in the style and manner of a spirited dialogue. The ease with which the entire volume may be converted into “Dialogues on Logic and Intellectual Philosophy," by means of its companion, the "Book of Questions," can only be equalled by the advantages which youth ever derive from catechetical instruction, possessing the sprightliness of living language, and familiarising the speakers to unpremeditated extempore discussion. If any thing can verify the observations contained in this Introduction, it must be the practice of the catechetical method which I now recommend-a practice which distinguished the instructions of Socrates, which Plato has preserved in his Dialogues, and to which Cicero has reduced almost all his philosophical writings.
