Logic as a Liberal Art An Introduction to Rhetoric and Reasoning



Logic as a Liberal Art An Introduction to Rhetoric and Reasoning
Logic as a Liberal Art: An Introduction to Rhetoric and Reasoning by Rollen Edward Houser
English | December 10, 2019 | ISBN: 0813232341 | 488 pages | PDF | 2 MB
In the twenty-first century there are two ways to study logic. The more recent approach is symbolic logic. The history of teaching logic since World War II, however, casts doubt on the idea that symbolic logic is best for a first logic course. [i]Logic as a Liberal Art is designed as part of a minority approach, teaching logic in the "verbal" way, in the student's "natural" language, the approach invented by Aristotle. On utilitarian grounds alone, this "verbal" approach is superior for a first course in logic, for the whole range of students. For millennia, this "verbal" approach to logic was taught in conjunction with grammar and rhetoric, christened the trivium. The decline in teaching grammar and rhetoric in American secondary schools has led Dr. Rollen Edward Houser to develop this book. The first part treats grammar, rhetoric, and the essential nature of logic. Those teachers who look down upon rhetoric are free, of course, to skip those lessons. The treatment of logic itself follows Aristotle's division of the three acts of the mind (Prior Analytics 1.1). Formal logic is then taken up in Aristotle's order, with Parts on the logic of Terms, Propositions, and Arguments. The emphasis in [i]Logic as a Liberal Art is on learning logic through doing problems. Consequently, there are more problems in each lesson than would be found, for example, in many textbooks. In addition, a special effort has been made to have easy, medium, and difficult problems in each Problem Set. In this way the problem sets are designed to offer a challenge to all students, from those most in need of a logic course to the very best students.

Leatherwork and Tanning (Heritage Crafts & Skills)



Leatherwork and Tanning (Heritage Crafts & Skills)
Leatherwork and Tanning (Heritage Crafts & Skills) by Lynn Huggins-Cooper
English | September 27, 2018 | ISBN: 1526724480 | EPUB | 128 pages | 2.2 MB
This book offers a whistle-stop guide to the history of leathercraft and tanning. The story begins in prehistory when people discovered, perhaps by chance, that skins exposed to smoke or accidentally soaked in autumnal puddles lasted longer. Skins were a valuable resource, used for everything from clothing to shelter, blankets and vessels. The book looks at evidence that shows us how tanning and leather continued to be of prime importance across the globe throughout history, in economic as well as functional terms.
