Title: Good old book
Review: I learned logic from this book, and so I am very fond of it. As a presentation of what was known at that time, it cannot be beaten. The only problem with it is that a lot more has been discovered, so a modern treatment of the subject is better for the beginner who wants to be properly informed. For this I suggest the books by Copi or even Kleene. But if you don't care about modernity, or have an interest in the way things used to be done, I strongly recommend this book. Also, I might mention that Hilbert's "Geometry and the Imagination" is good even for the modern mathematician.
