‘T his is a book for anyone,’ begins On Poetry, by the English poet Glyn Maxwell. It is a bold gesture, returning an ancient art to ‘anyone’ interested in it. Inasmuch as any book can be for everyone, On Poetry is such a book. It is funny, original, and doesn’t presuppose expertise on the part of the reader. It is the best book on reading and writing poetry for a general audience that I have ever read.
