The ArgumentRecent historiography of the Scientific Revolution has challenged the assumption that the achievements of seventeenth-century natural philosophy can easily be described as the ‘mechanization of the world-picture.’ That assumption licensed a story which took mechanization as self-evidently progressive and so in no need of further historical analysis. The clock-work world was triumphant and inevitably so. However, a close examination of one key group of natural philosophers working in England during the 1670s shows that their program necessarily incorporated souls and (...) spirits, attractions and congruities, within both their ontology and their epistemology. Any natural philosophical strategy which excluded spirits and sympathies from its world was condemned as tending to subversion and irreligion. This examination shows that the term ‘mechanical philosophy’ was a category given its meanings within local contexts and carries no universal sense separate from that accomplished by these natural philosophers. It also shows how the experimental praxis was compelled to treat souls and spirits, to produce them through experimental labor, and then to extend these experimentally developed entities throughout the cosmos, both social and natural. The development of mechanical philosophy cannot be used to explain the cognitive and social structure of this program, nor its success: instead, the historical setting of experimental work shows how a philosophy of matter and spirit was deliberately constructed by the end of the seventeenth century.

The ArgumentThis essay describes the emergence and stabilization in French and English experimental accounts, in second half of the seventeenth century, of the narrative sequence: X did (some process in the laboratory) and X saw (something happen), where X stands for a pronoun, I or we in English,je, nousoronin French. Focussing on the French case, it shows how the use of the collective pronounonin the experimental accounts registered in the files of the Académie des Sciences is directly related to the (...) will of this newly created institution to assert a collective authority on the production and legitimization of experimental matters-of-fact produced in the laboratory. It is argued, through the case of the discovery of the blind spot in the eye by Mariotte, that this new narrative form imbeds a construal of the experiment as a public spectacle, and of the proof as a witnessing event, which eludes the Academy's attempts to monopolize the process of fact validation and favors the diffusion and display of experiments in front of larger audiences. The question of whether a privileged witness such as the King of France who patronized the Academy could not have constituted by himself a suitable audience to ensure a full legitimization of experimental matters-of-fact while remaning within the bounds of academic practices is addressed. It is answered in the negative by providing evidence for the lack of interest of the absolute monarch in experiments. On the other hand, the outdoor practices of observation and measurement are shown to interfere in a constructive manner with the absolutist power and to capture the attention of the absolutist monarch, where laboratory experiments had failed. It is proposed that natural philosophers in the early modern period bear the burden of proof in buying credibility for the phenomena they try, by paying a tribute to the standing of the patrician elites that witness their experiments. This makes sense in a straightforward manner of the lack of interest of the King of France in a practice which exalts the power of the very group he is trying hard to control through the absolutist structure of power.

This paper analyses the different ways in which Isaac Newton employed queries in his writings on natural philosophy. It is argued that queries were used in three different ways by Newton and that each of these uses is best understood against the background of the role that queries played in the Baconian method that was adopted by the leading experimenters of the early Royal Society. After a discussion of the role of queries in Francis Bacon’s natural historical method, Newton’s queries (...) in his Trinity Notebook are shown to reveal the influence of his early reading in the new experimental philosophy. Then after a discussion of Robert Hooke’s view of the role of queries, the paper turns to an assessment of Newton’s correspondence and Opticks. It is argued that the queries in his correspondence with Oldenburg on his early optical experiments are closely tied to an experimental program, whereas the queries in the Opticks are more discursive and speculative, but that each of these uses of queries represents a significant Baconian legacy in his natural philosophical methodology.Author Keywords: Bacon; Experiment; Hypothesis; Method; Newton; Query.
