Walter Charleton and Early Modern Eclecticism

Eric Lewis

The publication of Michael Albrecht's Eklektik (1994) revived a small amount of scholarly interest in an early modern "movement" with a lineage that can be traced back to Clement of Alexandria, who described a method of constructing a philosophical system by selecting among different philosophical sects. ¹ Not surprisingly, the reception of Albrecht's work demonstrated the complexities associated with identifying the "movement" and categorizing those who labeled themselves "eclectic" philosophers; that is, those who seemed to expound a system of philosophy assimilated from ancient and modern sources. The difficulties involved with defining "eclecticism" and applying the term to early modern natural science is further complicated by the tendency for "eclectics" to categorize their contemporaries in ways that are counterintuitive to our modern sensibilities. ² Nevertheless, the proponents of this patchwork style of natural science are interesting precisely because they give us a glimpse into their interpretation of the state of philosophy and its relation to history during a time when the authority of The Philosopher was falling under ever increasing scrutiny.

The recent literature on philosophic eclecticism largely ignored the English context where rising sentiment against sectarianism influenced the formation of the Royal Society. ³ The perceived chaos of a nation divided and redivided by the multiplication of religious associations produced a plethora of proposals for the restoration and maintenance of intellectual and social order. In particular the problems of religious and political order motivated certain members of the [End Page 651] "Newcastle Circle" (largely Royalists) to construct philosophical methodologies at least congruent with their ideological commitments to social stability. Thomas Hobbes, Margaret Cavendish, and her close friend the physician Walter Charleton each offered his and her own style of natural science. ⁴ Both Hobbes and the Duchess of Newcastle were excluded from participating in the community of natural philosophers formed in 1660; yet Charleton became a founding member of the Royal Society that year. Despite relative neglect, Charleton's importance to understanding the development of modern natural science in England should not be overlooked; and particularly his prescribed method of doing natural philosophy needs more attention. ⁵ Like the radically different methods developed by Margaret Cavendish and Thomas Hobbes, Charleton's eclecticism should be viewed as an exhaustive effort to prescribe a remedy to the perceived threat of rampant sectarianism. ⁶ Unlike Hobbes and Cavendish, however, Charleton saw authoritarianism and dogmatism as the greatest challenge to order, and found the solution to that challenge in mitigated skepticism and a style of philosophy that did not make an epistemic differentiation between the novel philosophies of his day and those of the ancients.

Despite being a prolific writer, having a considerable reputation as a physician and placing himself in the center of the English community of natural scientists, Walter Charleton has been mostly ignored by modern scholars. In part this lack of attention can be attributed to the common view that he never developed a comprehensive philosophy nor maintained consistent metaphysical commitments. References to him claim that he was an "intellectual barometer of the age," ⁷ and his work has been described as "important as a case study in the reception of a mechanical philosophy." ⁸ His name is virtually absent from discussions concerning scientific methodology, though he is often described as a Renaissance [End Page 652] alchemical philosopher who fell under the influence of mechanistic atomism and the experimental agenda of a fledgling society of natural philosophers. Most accounts simply portray Charleton as a converted follower of the novel philosophy rather than as a novel thinker.

The failure to see Charleton as more than a converted empiricist and mechanist likely results from the opinion that eclecticism does not constitute a philosophical method as much as it constitutes the last refuge for scholars during periods of intellectual crisis. The article on eclecticism in Encyclopedia Britannica (fourteenth edition) states:

Eclecticism always tends to spring up after a period of vigorous constructive speculation, especially in the later stages of a controversy between...
