In this slide-show, harking back to personal holidays and expeditions prior to digital photography, Artist Mark Dion unpacks his practice of examining the ways in which dominant ideologies and public institutions shape our understanding of history, knowledge, and the natural world. Since the early 1990s, Mark Dion has been appropriating archaeological and other scientific methods of collecting, ordering, and exhibiting objects, the artist creates works that address distinctions between objective scientific methods and subjective influences. By locating the roots of environmental politics and public policy in the construction of knowledge about nature, Dion questions the authoritative role of the scientific voice in contemporary society.
