The tropics and the travelling gaze; India, Landscape and Science by David Arnold Permanent Black Delhi 2005
In the late 17th century, the identification of the temperate regions in Northern hemisphere as the normal, and the tropics as the other -- climatically, geographically, and morally -- gave rise to an imaginative geography, which continues to shape the production and consumption of knowledge, even today. In recent times, historians have problematised this notion of the 'tropical'. Much attention has been devoted to the writings of celebrated naturalists such as Alexander von Humboldt, Charles Darwin and Alfred Russel Wallace. The role of European scientific institutions and global networks in shaping the emergent fields of tropical botany, tropical medicine and tropical climatology has also been subjected to critical scrutiny. In the last couple of decades, Australian historian, Paul Carter's Road to Botany Bay has inspired historians to demonstrate that perceptions and practices imposed by West Europeans upon the landscapes and people of Asia, North America and Africa had significant impacts on local land-use policies, agricultural practices, and scientific and technological interventions.
India did not challenge the universality of Western science, either by presenting an alternative view of the natural world or by presenting challenges that could not readily reconciled with Western 'laws' and 'models.' Indeed, in being able to speak for the 'tropics' as well as for the 'temperate' world, Hooker exemplified the aspiring universality of 19th-century Western science and its practitioners.
Colonial science did draw upon indigenous tropes when it suited it, but that does not signify much trans-cultural engagement. Words such as 'jungle' were taken up and incorporated into the language of Anglo-Indian topography because they were a convenient way of referring to certain readily observable features and had a certain exoticism about them -- the kind that travel writers and medical topographers enjoyed in giving local colour and apparent authority to their work.
As always, Arnold's work is meticulously researched and lucidly written. But let's not forget that there is a growing body of work on indigenes challenging notions of tropical degeneracy. For example in Race, Place, and Medicine: The Idea of the Tropics in Nineteenth-Century Brazilian Medicine, J Peard studies the activism of the Tropicalista doctors, a group of physicians in 19th century Latin America, whose work challenged European theorists of tropical degeneracy. One hopes Arnold had engaged with works such as this.
