This article draws attention to several different practices of observation, manipulation, and experimentation with the surface of natural things. Beginning from the observation that the surfaces of natural things invited observation, manipulation, measurement, and re-configuration, with the promise to unveil the knowledge of depths, this article explores how practical knowledge about the surface of things and bodies led to new conceptions of nature and matter as composed of layers, corpuscles, and artificially reproducible solid parts in early modern Europe. This article (...) explores issues of knowledge production, and studies the ways in which material knowledge-making practices contributed to the habits of observing and experimenting with the surface of nature. By discussing three groups of cases in which nature was known by its surface and practice was mixed with theoretical appraisals of matter—surgeons, butchers, and food-cutters; gardeners and agronomists; and physicians—this article argues that “cognitive models” focusing on the description as well as the manipulation of natural surfaces informed both artisanal practices and natural philosophy, bridging the “high” and the “low” in the age of the “scientific revolution.”.

A review of economic thought since the sixteenth century reveals two streams of economic discourse, dirigisme and laissez-faire. Starting with the mercantilists, dirigiste approaches to economics embrace the real-world complexity of commodities that often differ greatly in attributes that are growth- and rent- augmenting. Most importantly, this means that free trade is likely to be polarising: it concentrates growth- and rent-augmenting commodities in countries that already enjoy a head start in these commodities. Advanced countries, therefore, support laissez-faire, while lagging countries (...) tend to support dirigisme. In order to rationalise their laissez-faire stance, advanced countries began developing a new economic discourse that strips commodities of their complexity. The foundations for this ideological reconstruction of economics were first laid by Adam Smith; this process eventually reached its climax with the neoclassical economists who stripped commodities down to one attribute: their capital intensity. In opposition to this laissez-faire economics, other writers, supportive of the interests of lagging countries, brought complexity back into their economic discourse; they argued that lagging countries had a fighting chance of catching up to advanced economies only by indigenising a growing array of growth- and rent-augmenting commodities.

A new political practice, the ‘reason of state’, informed the ends and practices of natural study in the late sixteenth century. Informed by the study of the Roman historian Tacitus, political writers gathered ‘secrets of empire’ from both history and travel. Following the economic reorientation of ‘reason of state’ by Giovanni Botero (1544–1617), such secrets came to include bodies of useful particulars concerning nature and art collected by an expanding personnel of intelligencers. A comparison between various writers describing wide-scale collections, (...) such as Botero, Francis Bacon (1561–1626), Jakob Bornitz (1560–1625) and Matthias Bernegger (1582–1640), reveals that seventeenth-century natural intelligencers across Europe not only were analogous to political intelligencers, but also were sometimes one and the same. Those seeking political prudence cast themselves as miners, prying precious particulars from the recesses of history, experience and disparate disciplines, including mathematics, alchemy and natural philosophy. The seventeenth-century practice of combining searches for secrets of empire, nature and art contests a frequent historiographical divide between empirical science and Tacitism or reason of state. It also points to the ways political cunning shaped the management of information for both politics and the study of nature and art. (shrink)
