If this perspective is uncommon it's largely because of how universities operate, how people have to specialize in life.

Duffy's poems resonate with me and revive that once-familiar image of man as a creature driven by the pursuit of knowledge and search for essential truths. The very first poem, Earthrise, is about an astronaut returning from one of the Apollo missions.

In the name
of science I had ascended
higher than
the mountain tops through all the shades
of day until there was only
night left

Several of the poems juxtapose the intellectual passion with the mundane, the domestic, and the chaotic. They bear witness to a world fast losing an appreciation for Mind/Spirit/Intellect – and do so in surprising and intriguing ways. We meet a professor 'in sloppy collegiate tweed' pressing a tea-bag against the side of the cup, who then squeezes past 'a sharp-tongued student holding court / on Derrida and the deconstruction of art'
(No prizes for guessing what the poet thinks of postmodern philosophy.)
Another poem looks at the invention of the microscope a kind of counterpart poem to Earthrise which begins the book. This time the new worlds opened up to human sight are the infinitesimally small. Duffy makes an imaginative leap:

“But in this I saw not just matter alone, but another light also
that penetrates further to the very notion of order,
beneath the base of the world and all we perceive

Duffy's poems, by and large, are not in the business of highlighting the absurdity of existence, fragility of reason, fragmented identity. Instead his poems reach out to a broader understanding of what it is to be human. Broader in the sense of including thirst for knowledge, encounters with the transcendent, and also in an expanded grasp of time and location.

It was the late 70s, time of cutbacks
and strikes, the dole queue never far
from mind. One morning on a picket line,
my dad got talking to a labourer from the depot
who had read The Illiad and was a respected
amateur antiquarian.

The sequence of poems which includes the lines above is a powerful and illuminating part of the collection. It's composed of memories of his father and the labourer from the depot, called PJ. This PJ is a lover of wisdom and artist. The poems in this section convey a thirst for knowledge and understanding, for the Logos of the Greeks. It is a real thirst, there among the other impulses and desires of daily life of ordinary people (i.e. working class).

Here's another few opening lines that are as good as any to illustrate Duffy's clarity and sense of place.

Things had gone wrong. I was a young man
lost, my mind struggling with the impossible
questions. I travelled alone by train to a place
by the sea where tall houses lined the seafront,
tall windows taking in the prospect.

Duffy tends to keep his language and rhythms pellucid, the knottiness and twists of these poems are in the meanings and situations presented. Some of these poems are close to flash fiction – I don't mean this detracts from them in any way.

Nietzsche and others viewed creativity as emerging from a Dionysian/Apollonian dialect. The Dionysian represents the visceral life-force, passions, intoxication. The Apollonian represents the search for truth, overcoming one's nature, light rather than heat, construction not destruction, a grasp of the extended self rather than immersion in the moment.

Duffy's poetry is Apollonian, refreshingly so. Rooted in his own life (including intellectual life), and not driven by what the news headlines proclaim are the pressing issues of the day.

I'll leave off with this verse from a poem called “The Older Artist” (presumably not a hugely successful one).

As I looked at one piece he came
and stood beside me in silence for a time,
then turned to me and gripped my arm fiercely,
saying, 'Somehow it all matters. It has to.
It fucking has to, doesn't it?'
