In the Winter issue of the Journal of Medieval and Early Modern Studies, Peter Harrison considers the “Sentiments of Devotion and Experimental Philosophy in Seventeenth-Century England” (2014). In particular, he focuses on the sentiments of chemist, physicist, and natural philosopher, Robert Boyle (1627-1691). In his Disquisition concerning the Final Causes of Natural Things (1688), Boyle argued that studying nature will excite “true Sentiments both of Devotion and of particular Vertues.” That is, the study of nature is a religious activity. As Harrison puts it, natural philosophy not only provides arguments for the existence of the Deity, it also induces “moral and religious sentiments in the investigator.”
Recent trends in history of philosophy demonstrate that “philosophy” was always more than mere theoretical argumentation and logical abstractions; it was, according to the late French philosopher Pierra Hadot, “a way of life.” In short, philosophy was a spiritual exercise. This “spiritual” element was present in early studies on nature. We see this not only in Plato, Claudius Ptolemy, and Simplicius, but also in the works of early Christian writers, such as Clement of Alexandria, Origen, and even medieval authors.
Harrison quickly moves on to the early modern period, particularly in the work of Francis Bacon. In a number of his treatises, Harrison observes, “Bacon framed his justification for the pursuit of natural philosophy in terms of the biblical narrative of the Creation and Fall.” The aim of natural philosophy was to regain control over nature, which was lost after Adam’s fall. Natural philosophy, in other words, was a restoration project. Experimentation was the labor required after the Adamic Fall. According to Harrison, the Protestant idea of a “universal priesthood” and personal piety were essential components to Bacon’s program.
Harrison then turns to Bacon’s successors, the Royal Society, which was founded in 1660. Harrison focuses on Thomas Sprat’s work on the History of the Royal Society (1667). According to Sprat, experimental philosophy undoubtedly reveals useful knowledge, but it also has moral ends. Natural philosophy, in short, purges moral deficiencies from the experimenter. But it also does more than this. Its also “promotes a properly informed worship of God.” Clergyman Joseph Glanvill and others would follow this Baconian program. In his “The Usefulness of Real Philosophy to Religion,” Glanvill affirms that “the Free, experimental Philosophy will do to purpose, by giving the mind another tincture, and introducing a sounder habit, which by degrees will last absolutely repel all the little malignancies, and setle in it a strong and manly temperment, that will master, and cast out idle dotages, and effeminate Fears.”
Returning to Boyle, Harrison observes that he “was also concerned to make an explicit case for the personal piety of the experimentalist.” For Boyle, natural philosophy not only revealed the power and wisdom of God, it also “promoted piety and particular virtues.”
Experimental activity, in other words, was a decidedly religious activity.
