Title: Seventeenth Century Science Bleeding into Literature through the Body of the Chimpanzee Proposal: There is a tension between Anglo-American culture and the chimpanzee. It comes from a shared but tenuous border of identification and projection, a border that has, from their first shared encounter, been tested and contested in text. Definitions of what makes humans human are continually readjusted, and what "human" signifies easily broadens, at times crossing species lines. In 1699, Dr. Edward Tyson first introduced "Natural Experimental Philosophy", and, with it, the English language, to the pygmy chimpanzee, or bonobo. His medium was a scientific treatise, Orang-Outang, sive Homo Sylvestris: or, the Anatomy of a Pygmie Compared with that of a Monkey, an Ape, and a Man. By claiming the bonobo was more like a human than what was then considered an ape, in both anatomy and behavior, Tyson established a sort of proto-primatology. Doing so required painstakingly refuting, line by line, the taxonomies of Aristotle, Galen, and other ancient logicians. Tyson's foundation was one that privileged method - repeatable, arguable experimentation and observation that self-consciously created potentially impermanent conclusions - over immutable authority. Tyson's break would inspire John Arbuthnot's parody of the weight afforded the works of the ancients in, "An Essay of the Learned Martinus Scriblerus, Concerning the Origine of Sciences". At the same time, Tyson used his Orang-Outang in conjunction with that book's companion piece, A Philological Essay Concerning the Pygmies, the Cynocephali, the Satyrs and Sphinges of the Ancients to demythologize "wild men" in literature. This second volume allowed the member of the Royal Society to extend his study and influence from nascent science to the popularly familiar realm of ancient literature. This study shows how science's precursors struggled to establish themselves in text as they carved out distinct, discursive spaces within the context of their contemporary culture. Tyson's seminal work with chimpanzees also provides an interesting view into the nature of human boundaries, both in their creation and erasure, through the mechanisms of an emerging science and institution of modernity.
