What do you think of David Kelley’s textbook “The Art of Reasoning?” How does it compare to Leonard Peikoff’s course “Introduction to Logic?”
If you are interested in something more in-depth, consider reading “Introduction to Logic”, by H.W.B. Joseph. It went out of print in the early 20th century but Harry Binswanger rescued it with a fresh copy.
Actually, Fred Weiss of The Paper Tiger, who posts on this forum, is the one who republished it as well as the wonderful Logic by Lionel Ruby. See http://www.papertig.com.

Well, if you are going to offer me this opportunity for unabashed self-promotion, what Tom may be thinking of is Harry Binswanger’s review of my edition.

But thanks for the plug.

Leonard Peikoff recommends Lionel Ruby’s “Logic” in his “Introduction to Logic” course. Kelley said at the time it was published that “The Art of Reasoning” was written as a replacement for Ruby’s book because “Logic” was out of print.
So both Peikoff and Kelley recommend you buy Lionel Ruby’s “Logic” from Fred!
Odd thinks from “The Art of Reasoning.”
Kelley’s definition of “definition” [p.32], “a statement that gives the meaning of a concept.”
Ayn Rand’s “A definition is a statement that identifies the nature of the units subsumed under a concept.”
But in the glossary Kelley has a second definition of “definition”, “A statement that identifies the referents of a concept by specifying the genus they belong to and their essential distinguishing characteristics .”
