It is absolutely vital to preserve a space where the mind, by means of poetic thinking, can move in a free, even anarchic, way. It must do so, in order to find deep truths that would not be otherwise available, ones that we desperately need. Anyone who writes poetry knows what I'm talking about, because they've had the experience of thinking this way.

For me, form is something I locate in the process of writing the poems. What I mean is, I start scribbling, and then try to form the poem - on a typewriter or on my computer - and, by trial and error, try to find the right shape. I just try to keep forming the poem in different ways until it feels right to me.

There is all this stuff about how sensitive poets are and how in touch with feelings, etc. they are, but really all we care about is language. At least in the initial stages of the process of writing the poem, though later other things start to come in, and a really good poem usually needs something more than just an interest in the material of language to mean anything to a reader.

Thinking in prose is different. I gained an immense amount of respect for people who write prose, and also felt even more sure that the thinking particular to poetry is essential to my life. I need to think, to explore, to question, in poetry. Without that feeling, I am, in some ultimate way, lost.

So for whatever reason those short lines just felt right to me, in my physical self. They were right for the movement of the poems. Some poems in the book have longer lines.

It's just interesting to me that the physical enactment of that mind moving has gradually changed for you in the last few years. It made me wonder if the change was deliberate in any sense, or procedural, like when A.R. Ammons stuck an adding machine roll into his typewriter to squeeze his verses into shorter lines.

Mimesis has longevity on its side. But Oasis wrote two of the greatest pop songs of all time, each with lyrics that mean less and less the more you think about them. So I'm going to have to go with the Gallagher brothers.
