LECTURE I. INTRODUCTION.
ONE of the most distinguished privileges which Providence has conferred upon mankind, is the power of communicating their thoughts to one another. Destitute of this power, Reason would be a solitary, and, in some measure, an unavailing principle. Speech is the great instrument by which man becomes beneficial to man: and it is to the intercourse and transmission of thought, by means of speech, that we are chiefly indebt|ed for the improvement of thought itself. Small are the advances which a single unas|sisted individual can make towards perfect|ing any of his powers. What we call hu|man reason, is not the effort or ability of one, so much as it is the result of the reason of many, arising from lights mutually com|municated, in consequence of discourse and writing.
