Abstract
The Argument: The overall portrayal of early modern experimentation as a new method of securing assent within a philosophical discourse sketched in many of the recent studies on the historical origin of experimentation is questioned by the analysis of the experimental practice of chemistry at the Paris Academy. Chemical experimentation at the Paris Academy in the late seventeenth and early eighteenth century originated in a different tradition than the philosophical. It continued and developed the material culture of the chemical work shops of the sixteenth and seventeenth centuries, and explored epistemic objects which had rather loose connections to philosophy. On the other hand, I argue against the classical dichotomy between the work of the mind that of the hand, and for an epistemology of experimentation that acknowledges that experimental manipulation goes hand in hand with reflexion. In particuler, I argue against the view that chemists at the Paris Academy were “pragmatists” who merely gathered experimental facts and classified substances and operations without perplexing themselves over general conceptions. I claim that the chemists at the Paris Academy constructed a general conception framework which shaped the significance of their experiments. This conception that I call conception of the chemical combination, compound and reaction was rather quickly reified into an experimental fact. Despite its generality it was a genuine chemical conception rather independent of philosophy.
