Many of the arts and sciences, which formerly resided exclusively in the colleges, and ministered only to the sons of opulence and leisure, have escaped from their retreat, and have become the hand-maids of the populace. But as respects logic, there still remains between the learned and the illiterate an impassable gulf. The uninformed look on the recondite structure of logic, and they are repelled by the difficulty of comprehending it, and wrap themselves up in absolute and obstinate ignorance, which they believe to be their destiny. The populace, in our manufactories, have to choose between subsistence and intelligence. For study, after protracted toil, they have not the strength--and to abridge their labour is to abridge their subsistence, and this they cannot afford. But because they are precluded by the destiny of civilisation from knowing much, they need not remain utterly unskilled in reasoning. Their natural good sense may be systematized, their natural logic may be reduced to some rule and order--though it may not be refined it may be practical, it may give power, and develop capacity now dormant. The hints, general rules, and elementary remarks dispersed throughout this work, will probably be of service to the uninitiated, perhaps put them on the road to higher acquirements, give them a confidence in their own powers, perhaps inspire them with a love of these essential studies, and impart a taste for the refinements which lie beyond. My hope is that many will be induced to consult scholastic treatises, and acquire that accurate knowledge which makes the society of educated people so interesting. Impulse has been given to knowledge, and the populace have begun to think, and both to speak and write their thinkings--and why should they not be enabled to do it free from obvious mistakes, and with a broad propriety commensurate with the native capacity they possess? Why should they, like a certain learned politician on a public occasion, propose, as a sentiment, 'The three R's, Reading, 'Riting, and 'Rithmetic?'* Why, in writing, should they not express themselves with strong grammatical coherence, and a certain bold perspicuity, if not able to reach refinement and elegance? Why, in pronunciation, should they not speak with a certain manly openness of vowel sound and a distinct articulation, if not with all elocutionary modulation? Why should not their discourse be expressed in brief, clear sentences? If their punctuation went no farther than placing capital letters at the commencement of sentences and of proper names, and periods at the conclusion of sentences, it would render their writings more intelligible than are half the communications they now send to the press. If they mastered only brevity and abrupt directness, and learned to omit tedious prolixity, they would command a hearing in many cases where now they are denied one. If in logic they made a shrewd mastery
