Lorraine Daston: "The Rise of Scientific Observation in Early Modern Europe"

Abstract

Observation is the most pervasive and fundamental practice of all the modern sciences, both natural and human. It is also among the most refined and variegated. Observation educates the senses, calibrates judgment, picks out objects of scientific inquiry, and forges communities. Its instruments include not only the naked senses, but also tools such as the telescope and microscope, the questionnaire, the photographic plate, the glassed-in beehive, the Geiger counter, and a myriad of other ingenious inventions designed to make the invisible visible, the evanescent permanent, the abstract concrete. Where is society? How blue is the sky? Which way do X-rays scatter? Over the course of centuries, scientific observers have devised ways to answer these and many other riddles—and thereby redefined what is under investigation by the way in which it is investigated. Observation discovers the world anew.

Yet scientific observation lacks its own history: why? Countless studies in the history and philosophy of science treat one or another aspect of observation: observation through telescope and microscope, observation in the field or in the laboratory, observation versus experiment, theory-laden observation. But observation itself is rarely the focus of attention and almost never as an object of historical inquiry in its own right. Observation seems at once too ubiquitous, too basic, and altogether too obvious to merit a history. One might well wonder whether a history of observation wouldn’t simply be the history of science in its vast entirety—or the still more vast history of experience.

Scientific observation is however a form of scientific experience as carefully crafted as the experiment – and it emerged, in tandem with the experiment, in the course of the seventeenth century. Previously, both terms had figured only rarely in natural philosophy: Experimentum and its vernacular cognates had previously referred to a trial or test, often conducted in the workshops of artisans; observatio had been since Greco-Roman antiquity associated with natural divination: the signs that portended storms, fat or lean harvests, or future destinies (as in the case of astrology). In the past twenty years, historians of science have written a rich history of how experiment rose to epistemological prominence in the sciences, but the story of how observation created a veritable empire by the mid-eighteenth century has yet to be told – a key chapter in the history of modern experience.
