John Armstrong hails from Scotland and is currently philosopher in residence at the Melbourne Business School. He is well known for several popular but elegant works on, broadly speaking, aesthetic matters: among them, Conditions of Love (2002), The Secret Power of Beauty (2004) and Love, Life, Goethe (2006). His recent book is more ambitious than its predecessors, but remains essentially in their fold.

Anyone who has found herself in a supermarket late on Thursday when a new checkout opens will have no trouble understanding why evolutionary biologists have struggled to explain the development of altruism in humans. In On Natural Selection, Darwin asserts: ‘In social animals [nature] will adapt the structure of each individual for the benefit of the community, if each in consequence profits by the selected change.’ Yet, practically, how could that adaptation first develop outside family groups? How could a lone altruist achieve anything but loss?

Ostensibly, Roger’s World is an account of Charles Siebert’s whistle-stop tour of primate retirement homes in America. By the author’s reckoning, there are approximately two to three thousand chimpanzees in America, as well as a substantial number of their primate cousins. He travels across the country, visiting captive chimpanzees on an ‘impromptu farewell tour of our own kidnapped and caged primal selves’, until he encounters Roger, with whom he feels a profound connection.

One of the keenest childhood memories of David Meredith, narrator of George Johnston’s novel My Brother Jack (1964), is of the hall of his parents’ suburban home in Melbourne. It was full of prostheses, the artificial limbs of servicemen returned, maimed, from the Great War. The men are friends and former patients of Meredith’s parents. Her mother was a nurse, her father served in the First AIF. The scant historical regard that has been paid to these damaged men, and to their families, is rectified by Marina Larsson’s brilliant study of Shattered Anzacs. Her subject is the cohort of revenants who returned to Australia after the war – their bodies ruined, shell-shocked, infected with venereal disease and tuberculosis – and the families, institutions and government bureaucracies into whose hands they fell.

If beauty is in the eye of the beholder and taste is subjective, why is there often overwhelming agreement that a particular thing is beautiful? Are tastes shaped by brain structure, unconscious psychic drives, society or culture? For almost half a century, the idea of innate, universal and cross-cultural aesthetics has been hotly contested in art theory and cultural studies. Now Denis Dutton argues that our aesthetic responses are instinctual. He has timed his book well. Freud has fallen from favour, post-modernism is generally despised and Darwin studies are on the rise.

The Bee Hut, Dorothy Porter’s fifteenth book, is a collection of poems written between 2004 and her death in December 2009. Many poems address mortality: ‘nothing lasts / not Forster. not Cavafy’s eloquent doomed mediocrities. not you.’ Another important motif is travel and how it affects the traveller. There are two almost contrary themes in the travel poems: the recurring image of the artist as vulture or vampire, destroying what feeds it; and the stately museum or gallery preserving the past intact: ‘I hold in my hand / the greedy, bleeding / pen / that has always / gorged itself’ (‘Blackberries’); ‘Each new ghost in my life / living and dead / smells of mulch’ (‘Vampire’).

Although Fourth Estate heralds this as Gary Crew’s first adult novel, readers who have followed his long career as a celebrated writer for young people will be aware that several of his Young Adult novels could be classified as ‘crossovers’. What defines them as such is the age and experience of their narrators: Kimmy of Angel’s Gate (1993) may be ten years old, but the story is told fifteen years later by an adult, Kim. Similarly, the teenage Sarah’s evidence indicts Mama Pratchett, but she relates the story of Mama’s Babies (1998) many years after the trial. Retrospective narration allows Crew to transcend the limitations of a youthful viewpoint and to look back upon events with mature wisdom, a technique he again employs in The Children’s Writer.

Jacob Rosenberg completed the manuscript of The Hollow Tree shortly before his death in October 2008. Born in Lodz in 1922, he lived there until he was deported to Auschwitz, where he lost his entire immediate family. He was later a prisoner in the Woflsburg and Ebensee concentration camps. In 1948 he and his wife, Esther, emigrated to Australia, where they raised a family and built a successful clothing business.

In a delightful memoir of a boyhood spent in Mussolini’s Italy, Umberto Eco recalled that the heady days of the Liberation in his small town near Milan were encapsulated in the taste of Wrigley’s Spearmint, given by an African-American GI (New York Review of Books, 22 June 1995). After the years of ‘palefaces in blackshirts’, these Americans appeared like exotic time travellers from the future. At the same time, the boy discovered that, unlike the long-winded Duce, large slabs of whose bombast schoolchildren were expected to commit to heart, the leader of the local partisans addressed the cheering crowd in the piazza with a few well-chosen and rhetoric-free words. Equally astonishing was the discovery that newspapers could carry opinions other than those mandated by the state.

Brenda Niall has the knack of lucid multi-focus, a great thing in a biographer. That organisational deftness, an ability to keep the tangled loops of people’s lives spooling freely through her fingers while she projects a rich and dramatic context for them, was evident in her group study of The Boyds (2002), and it is the structural virtue in this new work, The Riddle of Father Hackett.
