Abstract

The rise of XVIIthcentury natural philosophy determines a significant break with the tradition and enthe idea of a new beginning of scientific investigation grounded on mathematics and experiment; at the same time, the diffusion of printed books represents an essential factor for the dissemination of the new philosophy. The ideal of the book, as an expression for this new philosophy, results from the speculation about the correspondence between the language and structure of the philosophical book and the “book of nature” written by God. At the same time, the pursuit of this ideal requires the critical knowledge of the book tradition and the awareness of the imperfection that characterizes any given accomplishment of the ideal. This inner tension finds an exemplary solution in Newton’s Principia mathematica, where the incompleteness of the book of natural philosophy is recognized as an intrinsic feature, which directs Newton’s own selection and ordering of the material in the process of editing his work. After Newton, several attempts have been made to recover the systematic unity of natural philosophy in a single book, in a system of books or in encyclopaedies. In late XIXthcentury, as the specialization and multiplication of scientific disciplines establishes the impossibility to master natural philosophy as a whole, the intrinsic historicity of natural philosophy is recognized as a crucial factor of scientific thought itself. This significant change of perspective, compared to early modern philosophy, produces the need for different ways of understanding the unity of science and the role of books in scientific practice. Nowadays several distinguished scholars in the history and philosophy of science underscore the need to restore the historical awareness of late XIXth-early XXthcentury science among scientists, in order to promote the development of new scientific ideas.
