Professional career

Electing to remain in Australia, Brook continued to work as a sculptor and as art critic of the Canberra Times under John Pringle's editorship. From 1968 he became art critic of the Sydney Morning Herald, when he was appointed as one of the three first academics in the new Power Institute of Fine Arts in the University of Sydney. During this period (1968-1973) he was an energetic initiator of the "Tin Sheds" workshops, where his promotion of what he then called "post-object art" (more generally referred to at the time as "conceptual art")^[2] was found liberating by many of the younger artists.

His 1969 John Power Memorial Lecture "Flight from the Object"^[3][4] proposed a radical alternative to the ideas that animated Clement Greenberg's 1968 Power Lecture "Avant-garde Attitudes". Australian painters had generally taken their options to be restricted to the choice of international mainstream modernism or the purposeful construction of a distinctively Australian style.

In 1973 he was appointed to the inaugural chair of Fine Arts at Flinders University in Adelaide, where he contentiously changed the departmental name from "Fine Arts" to "Visual Arts". He initiated theoretical studies in the psychology and philosophy of visual perception and introduced a study of Aboriginal visual culture in a context where European art history had previously dominated. At that time no practical studio courses were offered in any Australian university. From 1974 he initiated the Experimental Art Foundation in Adelaide. This was partly designed to enrol practising artists, along with academics and theorists, to bridge what he called "the gap between town and gown". He also introduced postgraduate academic programs for practising artists.

Brook abandoned art criticism after leaving Sydney, and published extensively thereafter in journals of informed opinion and more popular media as well as in the academic literature. He retired from Flinders at the end of 1989 and lived in Cyprus from 1990–92, returning temporarily to a part-time role at the University of Western Australia in Perth, before settling again in Adelaide.

Theoretical contributions

Although they are wide-ranging, Brook's philosophical interests have centred on two principal regions of speculation: to understand the nature and place of perception and non-verbal representation in the visual arts, and to elucidate the relationship between art, the histories of works of art and the dynamics of cultural evolution. His early work on perception was first publicly aired in "Perception and the appraisal of sculpture",^[6] in which the important distinction he later draws between matching and simulating non-verbal representational practices is introduced as a difference between what he calls the "object accounts" and the "picture accounts" that we spontaneously give of visually perceived things; notably of three-dimensional works of art. Crucial to his thinking is the idea that non-verbal representation is not a quasi-linguistic form of communication. It relies on the de facto socially efficacious substitutability of one thing for another thing even in cases where relevant properties are not shared. He argues that this perceptually mediated substitutive felicity must have been available to pre-linguistic organisms or language itself could not possibly have evolved.

Brook's elucidation of the concept of art, as what he at first called "experimental modelling of actual and possible worlds", is first comprehensively spelled out in his paper "A New Theory of Art".^[7] This rather complex theoretical structure underwent continuous modification in numerous publications as his memetic account of cultural evolution developed. He embraced Richard Dawkins' concept of the meme as the potent factor in cultural evolution, analogous to the function of the gene in biological evolution. However, he differed significantly from Dawkins and other meme-theorists in his way of understanding and exemplifying the meme. Instead of offering such examples as the popular song or catchphrase he insisted that these things are items of a cultural kind analogous to the items of biological kinds such as a horse, or a cabbage. Just as a horse is the product of appropriately activated genes, he argues that a popular song or a catchphrase is not itself a meme. It is an item of a predictable cultural kind that is generated by exercising memes. Memes are purposefully directed actions that can be exercised in concerted ways, as contrasted with mere behaviours. This is first unambiguously elucidated in his paper "Art History?".^[8]

Brook's account of art as the essentially unexpected recognition of the viability of new memes is spelled out in his book The Awful Truth About What Art Is (2008).^[9] It is succeeded by his semi-autobiographical book Get A Life (2014),^[10] in which an anthology of his papers on perception, representation, art, evolution and history is threaded together along a string of text that is intended to place them in the context of his personal history and experience.
