Objectivity and the Escape from Perspective

Scientific objectivity is neither monolithic nor immutable: our current usage is compounded of several meanings - metaphysical, methodological and moral - and each meaning has a distinct history, as well as a history of fusion within what now counts as a single concept of `objectivity'. The rise of aperspectival history in nineteenth-century science is one strand of this plaited history of objectivity, as embodied in scientific ideals and practices. It is conceptually and historically distinct from the ontological aspect of objectivity that pursues the ultimate structure of reality, and from the mechanical aspect of objectivity that forbids interpretation in reporting and picturing scientific results. Whereas ontological objectivity is about the fit between theory and the world, and mechanical objectivity is about suppressing the universal human propensity to judge and aestheticize, aperspectival objectivity is about eliminating individual (or occasionally group) idiosyncracies. It emerged first in the moral and aesthetic philosophy of the late eighteenth century and spread to the natural sciences only in the mid-nineteenth century, as a result of a reorganization of scientific life that multiplied professional contacts at every level, from the international commission to the well-staffed laboratory.
