Garrison Keillor's introduction, though, is definitely worth reading, I'll quote some of it here:
Poetry is free speech. It is ever on the side of the irrepressible spirit and in opposition to the censor, to Management, to the protocols of the company psychologist, to the roomful of men in blue suits who casually cheat schoolchildren. It is on the side of exhilaration and the stupendous vision, the sight of the stars through the barred window, the perfection of small birds, the democracy of their chittering language and of our own yakfest and hullabaloo. Poetry is made of the grandeur that is available to a man with no fortune but with somewhere to walk to and ears to hear and a mind to transport him. He may be defeated in love and finance and yet the night belongs to him, he feels entrusted with the stunning sky, the guardian of the houses on the street and all the people in them. So are poets, the angels and shepherds of the sleeping world.
The poems in the book are not ones that I would have chosen, but I don't often enjoy modern poetry that neither rhymes nor scans, and there is a lot of that in this book. But, I thought I'd take this opportunity to mention a poet that I adore: Badger Clark.
Ayn Rand quoted, briefly, his poem "The Westerner", in The Romantic Manifesto, so being curious I looked it up to read the whole thing. Mr. Clark captures the essence of the cowboy, the solitary man facing the wide-open world alone and unafraid so perfectly that you can almost smell the fresh air.
If you know of more poets like this, please, recommend them. Hard times come when you least expect them and you need some grandeur close at hand when that happens.
