“I have a confession to make: I don’t really understand poetry.”

So goes the opening line of poet Matthew Zapruder’s forthcoming book “Why Poetry,” which looks at why a lot of people feel alienated by poetry (this line is one he’s heard countless times before) and what can be done to remedy that.

The book is part personal, part explanatory and part polemic, saying: Here’s my experience with poetry, here’s how it works, and here’s why we desperately need it. It is the last part that is perhaps most interesting in an age of information overload. Zapruder argues poetry is a necessity, because the knowledge we gain from it can be deeper and more human than from other texts.

“It’s an intuitive, associative understanding that you can get from poems, which can really open a person up and make them aware of other human beings, of themselves, and of the natural world,” said Zapruder, who has published four collections of poetry and edited the poetry page of the New York Times Magazine. “It does that in a way that can’t be done by any other form of writing.”

But this intuitive, associative power, he says, can be lost on people because of the way poetry is taught. He argues that we are too often asked to find the “hidden meanings” in poems, as if a poem is a riddle — telling you something simple, but in the most complicated way possible, as if the poet is being deliberately opaque. Good poetry actually does the opposite, says Zapruder; “it’s something elusive and complex, said in the simplest way possible.” (Though writing about the complexities of life is not always very simple.)

Throughout the pages of “Why Poetry,” Zapruder traverses the poetry of Frank O’Hara, Sappho, Langston Hughes, John Keats, Adrienne Rich and many others, using a wide range of poets and styles to illustrate how poetry can function in many different ways. He unpacks both how their poetry works (through the technique of “defamiliarization,” for example, of making the familiar strange) and also the feeling and imagination they inspire (often, he says, poems provoke both longing and confusion).

In the end, Zapruder said he was happy to have finished writing “Why Poetry,” and to be able to go back to writing poems, instead of about them.

“Writing this book reminded me of the very thing I was writing about,” he said. “Which is that there is a different kind of knowledge, and a different kind of experience, to be gained when writing poems. A search for dream knowledge. It’s a pleasure to get back to that.”

Below, read one of Zapruder’s poems, “I Wake Up Before the Machine,” and listen to him read it aloud.

I Wake Up Before the Machine

By matthew Zapruder

I wake up before the machine

made of all the choices

we are together not making

lights up this part of Oakland

it’s dark so I can imagine

another grid humming in the east

already people are deciding

I lie in the western

pre-decision darkness and almost

hear that silent voice

saying go down there

the coffee needs you

to place it in the device

its next form will help you remember

daylight is coming

but dreams do not go away

they just move off and change

your mind is a tree

on a little hill

surrounded by grasses

that look up and say

father wind

loves moving through you
