These papers are now available on microfilm as Letters and Papers of Robert Boyle, edited by Hunter, Michael (Bethesda, MD: University Publications of America, 1990)Google Scholar. In quoting from the Boyle Papers I have omitted Boyle's deletions; his insertions are in angle brackets ((,)), and conjectural readings are in braces ({,}). Boyle used slashes (/,/) to enclose alternative words or phrases, and the manuscripts do not reveal any final decision on his part. Like most workers on the Boyle manuscripts, I owe a debt of gratitude to the Librarian and staff of the Royal Society Library, and also to Michael Hunter for his extremely helpful finding list. References to Boyle's published works are to Birch's, Thomas 1772 edition of The Works of the Honourable Robert Boyle, 6 vols. (London, 1772; rpt.

2 I am following R. E. W. Maddison in taking 1647 as a plausible date of com position (The Life of the Honourable Robert Boyle [London: Taylor & Fran cis, 1969], p. 41, n.). The MS is in the form of a letter (BP 37.186r-193v), but there is no indication of the intended recipient of the letter, if indeed there was one. Malcolm Oster suggests Boyle's Sherbourne neighbour, Nathaniel Highmore (Oster, Malcolm, “The ‘Beame of Diuinity’: Animal Suffering in the Early Thought of Robert Boyle,” British Journal for the History of Science, 22 [1989]: 151–80; reference at p. 161)CrossRefGoogle ScholarPubMed, but it also quite possible that the epistle form was merely a stylistic device adopted by Boyle. The MS is tran scribed as an Appendix to Oster's article. My transcription differs from his in minor details.

3 Boyle thought that building hospitals for “poore sicke, maimed & decrepit beasts” revealed “a Compassion that possibly degenerates into Fondnesse” (BP37.193r).

49 Boyle recalls that as a child “the first course I tooke to satisfy my Curiosity, was to instruct my selfe in the Aristotelian Doctrine, as that whose Principles I found generally acquiesc'd in by the Vniversitys & Schools, & by numbers of celebrated Writers, celebrated for little lesse, then Oraculous. But I had scarce (well) acquainted my selfe with the Peripateticke Theory, before I was strongly tempted to doubt it's Solidity. For the Commands of my Parents engaging me to visit diuers forreigne Countrys, I could not but in my Travells meet with many things capable to make me distrust the Doctrine (wherewith) I had freshly been imbu'd” (BP 38.80r).

Thus, “tho I much reuerenced the rare abilityes of that (Greate) Philosopher,” the Aristotelian doctrine was found wanting. Nonetheless, the views of Aristotle on the soul, as opposed to his views on natural philosophy, are nowhere explicitly rejected by Boyle. Even though Boyle quotes with apparent approval Descartes on perception, he is far from rejecting other possible theoretical stances in this area.

53 Ibid. Although Boyle was contemptuous of “the great noise made by vulgar Philosophers of their Substantial Forms” (BP 9.28r), he entered the follow ing caveat: “whenever I shall speak indefinitely of substantial forms, I would always be understood to except the reasonable soul, that is said to inform the human body, which declaration I here desire may be taken notice of once for all … Nor am I willing to treat of the origin of qualities in beasts; partly because I would not be ingaged to examine of what nature their souls are, and partly because it is difficult enough in most cases (at least for one that is compassionate enough) either to make experiments upon living animals, or to judge what influence their life may have upon the change of qualities produced by such experiments” (Origine of Forms and Qualities, in Works, 3.12).

54 Overton, Richard, Man Wholly Mortal (London, 1655)Google Scholar. Noting that “Neither Milton nor Overton was an atheist,” J. R. Jacob suggests that “less radical thinkers saw a threat of atheism or at least of disorder in the mortalist's posi tion.” Jacob explicitly includes Boyle in this group (Jacob, J.

55 Digby, Two Treatises, 2.86. C. P. Hill says that “As a scientist,” Digby “was by the standards of his day a mediocre amateur, and the greatest British practi tioners, like Boyle and Newton, thought very little of him” (Who's Who in History, Vol. 3, England 1603-1714 [Oxford: Basil Blackwell, 1965], p. 77), but I do not know of any textual support for the claim that Boyle “thought very little” of Digby. There is, however, ample textual support for the opposite claim. At BP 26.162, for example, Boyle refers to “our deseruedly famous Countryman Sr Kenelme Digby” in his discussion of atomism, and in March 1660, Oldenburg noted that his writing to Boyle of his “dislike of Mr. Digby … may be a mistake, perhaps” (Hall, A.

89 Not only Cartesian philosophers would be willing to make a case against such a suppressed premise. Aquinas, for example, argued that: “it would be absurd to speak of having friendship … for a horse” (Summa Theologies, 2^a2^ae 23.1 resp.). Though Descartes is concerned with horses, and St. Thomas with friendship, the conclusion in each case is the same.

90 BP 191v, marg. Nimrod is mentioned as a mighty hunter at Genesis 10.8-9.

91 In his early essay “On sin,” Boyle offers Domitian as an exemplar of “Egre gious Wickedness” (Harwood, The Early Essays and Ethics of Robert Boyle, p. 145). However, though Domitian was clearly not a model of morality, Betty Radice has suggested that “there is no evidence of the widespread per secution attributed to him by later Christian apologists” (Who's Who in the Ancient World [Harmondsworth: Penguin, 1973, p. 107a]).

92 BP 37.191v. Boyle seems to be simply wrong about this: “it was widely believed in the early modern period that butchers were ineligible for jury ser vice in capital cases, owing to their cruel inclinations. There seems to have been no legal authority for this notion, but it was held throughout the sev enteenth and eighteenth centuries by scores of commentators who should have known better” (Thomas, Man and the Natural World, p. 295).

93 Schopenhauer, taking Kant to task, writes: “so one is only to have compassion on animals for the sake of practice, and they are as it were the pathological phantom on which to train one's sympathy with man!” (Schopenhauer, Arthur, The Basis of Morality, translated by Bullock, A.

96 BP 37.188r-188v. The reference is to Genesis 1.31: “And God saw every thing that he had made, and, behold, it was very good.” Boyle here omits the point that was often made on the other side: that the earlier “Generall Suruey” (after the creation of the other animals, but before the creation of humans, Genesis 1.25) simply led to the judgment “good” as opposed to “very good.” See, for example, Burroughes, Jeremiah, Gospel Reconciliation (London, 1657), p. 6Google Scholar.

103 Boyle, Usefulness I, 2.17. There are manuscript passages in which Boyle makes the point even more strongly. For example: “I think y^t Adam alone, on y^e account of his Immaterial soul endowd with reason & free will, was a more excellent creature than al y^e (beasts &) birds & other animals he gave (names) to, with y^e whole teraequeous globe y^t they inhabited, to boot” (BP 1.66r).

104 Boyle, Usefulness I, 2.67. Experimenting on humans was clearly of interest to Boyle. Later in this same work he returned to the topic when discussing the strong emetic crocus metallorum (an oxysulphide of antimony). Noting that after two ounces of crocus metallorum had been injected into a dog, “he vomited up life and all, upon the straw, whereon they had laid him,” Boyle “proposed, that if it could be done, without either too much danger or cruelty, trial might be made upon some human bodies, especially those of male factors. And some months after, a foreign ambassador, a curious person, at that time residing in London, did me the honour to visit me, and informed me, that he had causedtrial to be made with infusion of crocus metallorum, upon an inferiour domestick of his, that deserved to have been hanged; but that the fellow, as soon as ever the injection began to be made, did (either really or craftily) fall into a swoon, whereby being unwilling to prosecute so hazardous an experiment, they desisted; without seeing any other effect of it, save … that it wrought once downward with him, which yet might, perhaps, be occasioned for fear or anguish” (Boyle, Usefulness I, 2.89). The foreign ambassador was the French ambassador, the Due de Bordeaux. The experi ment took place in 1657 (Timothy Clarke to Oldenburg, April/May 1668, Oldenburg Correspondence, 4.357, 366).

109 Quoted by Solomon Diamond in his Introduction to Willis's Two Discourses, p. v. Boyle knew Willis personally; indeed it was Willis's recommendation of his then assistant Robert Hooke that secured Hooke a similar post with Boyle. They were in close communication when Boyle was in Oxford-though Willis was only five years older, Frank speaks, somewhat surprisingly, of Boyle as being one of “Willis's younger friends and proteges” (Frank, Harvey and the Oxford Physiologists, p. 169)-but Boyle mentions Willis on the half dozen or so occasions when he does refer to him in the published works with a kind of distanced respect. He was clearly dubious about Willis's chemical theories, and does not refer to his neurophysiological views in connections where one might have expected such a reference although, as his correspond ence makes clear, he was acquainted with his fellow Royal Society member's works, including his Cerebri anatome.

Aristotle had argued (De Anima, 431^a15-17) that “the soul never thinks without an image,” and St. Thomas agreed: “In the present state of life in which the soul is united to a passible body, it is impossible for our intellect to understand anything actually, except by turning to phantasms” (Summa Theologiae 1.84.7 resp.).

130 God is required in two ways: to create the soul and perform the “physical miracle” (BP 2.62) of joining it to the body; and to sustain the laws (which are not laws of nature, and are not mechanically explicable) that allow body and soul to interact.
