CHAPTER II. LOCKE-LOGIC.

 Logic¹ is a general guide to the discovery of truth, and teaches us its systematic² communication to others. This definition is intended to combine logic and rhetoric³ into one system. According to a quotation⁴ in Pinnock's Guide to Knowledge, Locke defined logic as 'that art by which we rightly use our mental faculties⁵ in the discovery and communication of truth,' a definition, called by the writer, the definition of nature echoed by genius. There exists a natural connection between logic and rhetoric. The discovery of truth could avail us little if we were without the means of communicating it; and it is easy to see that it would be in vain to possess the means of communicating truth, unless we had the truth to communicate. Therefore, ingenuity⁶ is but ill employed in separating these mutual⁷ departments of learning which nature has connected together. Besides, the skill of the logician⁸ is as serviceable in the statement of a case, as in arguing it. Arrangement is as much a matter of logic as ratiocination⁹; and to impress this neglected truth upon the young inquirer, is one reason for proposing a combined definition.

The mutual connection of logic and rhetoric is illustrated¹⁰ by the fact, that the Logic of the Schools is purely¹¹ a branch of rhetoric. It consists in putting an argument into 'the most perspicuous form in which it can be exhibited,'*—i. e., in communicating it in the most efficient way to others.

     * Dr. Whatetly: Anal. Ont., chap. 1, aec. 6, p. 45.

Indeed, Dr. Whately (who makes logic to consist in reasoning) defines reasoning as discourse¹², and discourse is rhetoric. 'Grammar,' says Doherty,' represents the mechanism¹³ of letters in forming words—Rhemar, the mechanism of words in forming sentences. We have Grammar for letters, Rhemar for words, Logic for arguments, and Rhetoric for discourse.' Locke-logic, therefore—i. e., logic in the sense in which Locke treated it—seems to come nearer the truth, as well as nearer the common requirement, than the restricted definition of it by others insisted on.
