This is a book about warfare, battles and the preparations for them. It is not comprehensive but it is systematic, for it selects major periods or episodes in Western military history in the last one thousand years and, by applying economic theory, tries to pluck lessons from them. It extends from the mania for building fortified castles in medieval times to the bombing of Nazi Germany and the economics of the recent crusade against terrorism.

When applied to art and literature, the word ‘serious’ can be used to suggest a work is substantial and important, not necessarily that it is the opposite of humorous. There is a sense in which Rabelais and Cervantes are serious writers. But the slippage between these two meanings – the fact that our language permits a casual conflation of worthiness and sincerity – reflects a long-standing cultural prejudice which relegates comedy to a second tier, as if a talent for provoking laughter were somehow less praiseworthy than a talent for inspiring pity and terror. Tragedy is often assumed to be profound and ennobling, but comedy’s levelling tendencies, the anarchic implications of mockery and unbridled laughter, are apt to be viewed with suspicion.

Books may furnish a room but they also furnish the mind. As somebody once said, ‘A man is known by the company his mind keeps’. One of my first moves on visiting a home is to check out the bookshelves, to discover something about the owner’s mind. Bob Carr, New South Wales’s longest-serving premier, has conveniently outlined his reading life in this opinionated, sometimes infuriating but always compelling account, which allows us to read his mind without physically visiting his library.

A Fraction of the Whole is Sydney author Steve Toltz’s sprawling début. Wearing its misanthropic heart uproariously on its sleeve, Fraction is a long father-and-son tale that traverses continents and nods to countless literary forebears on its way.

Another poet might invoke Edmund Burke’s famous treatise on the Sublime and the Beautiful as a piece of phraseology or a pleasing adornment, but with John Kinsella, such a title is dead serious. Elliot Perlman’s superb novel Seven Types of Ambiguity (2003) ingeniously makes the reader think of William Empson’s, and the idea of plural signification it evokes, but not instantly to reread it. Kinsella’s use of Burke’s title prompts one to reread the original – ideally, in a Kinsellan métier, on the internet, late at night. Additionally, the ‘shades’ in Kinsella’s title is an important supplement – shades as variations, colourings, but also shadows, undertones.

Pitched awkwardly between mass-market romance and a literary novel, Musk and Byrne is a curious creation. Spending excessive verbal effort on a familiar and rather vacuous plot, the book never finds a satisfactory shape, and finally lacks a true purpose. Never intellectually thorough enough to offer an exploration of artistic identity, and not trashy enough to deliver tawdry thrills, it is both too well written and not very original.
