In late 1999, NASA announced that its Mars Climate Orbiter, a multi-million-dollar robot probe designed to study the weather and climate of Mars, was lost somewhere in space. The craft had failed to manoeuvre into its optimal orbit, ending either on a course towards the sun or in a fatal collision with the red planet. Investigations uncovered the source of the blunder: one team working on the orbiter had been using metric measurements, another team had been using imperial.

Autofiction differs from autobiography in that, to use Jean Genet’s formula with which Édouard Louis opens his latest novel, Change: A novel, the self is nothing but a ‘pretext’. In Louis’ case, it is a pretext for exploring the self as a sociological, rather than psychological, phenomenon; the enduring product of the social class in which it was forged. Change (first published in 2021 as Changer: méthode) opens with the narrator, Édouard (né Eddy), sitting at his desk writing what will become the novel we are now reading. His objective: ‘to fix the past in writing and, I suppose, to get rid of it’. This will prove easier said than done. As Édouard later discovers, the past has a way of reinstating itself, like a pendulum which is always restored to equilibrium. It is, however, less this resting place than the oscillations that Louis is interested in recording.

Kevin Hart’s Dark-Land is the memoir of a distinguished poet and scholar who was born in England in 1954, moved with his family to Queensland when he was eleven, and migrated again in 2002 to the United States, where he is currently Professor of Christian Studies at the University of Virginia. Dark-Land is well-written and amusing, with memorable vignettes ranging from his time in a London primary school to his bonding as an Australian teenager with his cat Sooty. On a wider spectrum, though, Dark-Land addresses more weighty concerns around time, memory, and intellectual or religious illumination. He recalls as a child listening to a BBC performance of the allegorical journey invoked in John Bunyan’s Pilgrim’s Progress, and he describes himself now as ‘still clambering up the hill I had known since childhood in London’. The title of his memoir signals this putative passage from darkness into light.

From across the ditch, New Zealand can look like a place where settlers and Indigenous people have forged a successful, postcolonial modus vivendi. The image conceals more than it reveals. As in Australia, relations between Indigenous people and the state are fraught. At the November 2023 election, right-wing minority parties won electoral support by rejecting what they have characterised as special privileges to Māori. And a long-standing, bipartisan consensus on ‘biculturalism’ is breaking down.

Shortly after Black Saturday, David Lindenmayer was giving a seminar on post-bushfire recovery when a member of the audience yelled out, ‘If it wasn’t for you greenies, none of this would have happened.’ Lindenmayer’s response was neither defence nor attack, but rather to rephrase the man’s words. ‘Your hypothesis,’ he said, ‘is that a fire in a forest that is logged and regenerated will be less severe than a fire in an intact forest.’ Many years of research followed this heckle. The result? A counter-intuitive finding that fire severity increases in logged forests.

Identity is a hard thing to define. What makes us who we are? We have social identities, shaped by our affinities and proximities to social groups, cultural identities informed by values, languages, rituals, traditions, and a whole multitude of different phenomena that combine to make us who we are.

‘Everyone allows that the talent of writing agreeable letters is peculiarly female.’ So said Jane Austen in Northanger Abbey. Even allowing for Regency hyperbole, there is some truth in the sally. We think of the inimitable letters of Emily Dickinson, who once wrote to a succinct correspondent: ‘It were dearer had you protracted it, but the Sparrow must not propound his crumb.’ In 2001, Gregory Kratzmann edited A Steady Stream of Correspondence: Selected Letters of Gwen Harwood, 1943-1995. Anyone who ever received a letter or postcard from Harwood – surely our finest letter writer – knows what an event that was. She was nonpareil: witty, astringent, frank, irrepressible. Now we have this welcome collection of letters written by Elizabeth Harrower and Shirley Hazzard (unalphabetised on the cover, in a possible concession to the expatriate Hazzard’s international fame).

Decolonising has reached the classics. Complexity, diversity, and entanglement are in. Greece and Rome are, well, out. The movement to ‘reclaim’ Antiquity began with noble aims: to emancipate the ancients from the prism of politics and war through which we like to see them, to emphasise the role of technology and trade in their lives, and to make women and people of colour visible among them again. Alas, decolonisation all too often seems to have descended into ugly arguments over restitution of artefacts (Elgin marbles, anyone?) or the skin shade of this or that Roman notable (Septimius Severus or St Hadrian of Canterbury, for example). Books such as Josephine Quinn’s are the sensible, balancing side of the equation, an antidote to so much virtue signalling and grievance mongering. Quinn’s is an ancient world decentred – provincialised, to invoke Dipesh Chakrabarty’s celebrated term. Greece and Rome remain, but must jostle with others for attention, space, and significance. The argument is simple. Antiquity was far more multipolar, dynamic, and integrated in reality than in the civilisational – and, indeed, civilising – narratives that Europeans since Petrarch have been telling themselves about it.

In Joseph Conrad’s Heart of Darkness (1899), the sailor Charles Marlow recalls captaining a river steamer in the Belgian Congo, a venture that becomes a search for the colonial agent Kurtz, said to be a brilliant if infamous ivory trader, who is ill and possibly mad. Marlow’s journey, of course, becomes a passage into psychological as well as (to the European mind) geographical darkness, and offers a damning portrait of Western imperialism.

One of the joys of reading – and a point of difference from narratives told on the various screens we turn to for leisure – is imagining a story’s mise en scène. Our mental pictures (termed phantasia by a group of British neurologists) are a strange alchemy of images from our memories, thoughts, and dreams. Though visualisation is not a universal experience, many readers may comment that a book-to-film adaptation was ‘exactly as I pictured it’ or else ‘nothing like what I saw in my mind’s eye’.
