This book was my introduction to Stanislaw Lem, which is ironic, because this is a book consisting only of introductions of other (imaginary) books. I found it completely by accident on the bargain rack, and I don't know why I bought it. But I did, and I'm certainly glad. When I started reading him, I said to myself, "What *is* this?" and found it all very bizarre. But Lem is one of those rare writers who makes you feel smarter just for having read him. For all that, this book is not only fascinating, but surprisingly funny at times. (How do you write an introduction to a book of introductions?) And for being so fanciful, Lem's discussions are surprisingly relevant.
