The role of the telescope and microscope in the constitution of the Idea of scientific progress

Abstract

ABSTRACTThe invention of optical instruments showed that the extent of human experience is not eternal and natural but contingent – it can change, depending on the availability and performance of optical instruments over time. This knowledge of the temporal variability of empirical knowledge led to changes in the methodology and epistemology of early modern natural philosophy. In this article, I focus mainly on three aspects of this process. Firstly, optical technique has shown that nature cannot be examined by an isolated individual. Natural philosophy must be a collective activity with institutional support. Secondly, use of optical instruments led to an understanding of the relativity of contemporary natural philosophy, no longer understood as the culmination of preceding development. The present state of natural philosophy becomes a transient stage in a longer development. Thirdly, telescopes and microscopes contributed to the formation of an idea of unending progress.
