The ArgumentRecent historiography of the Scientific Revolution has challenged the assumption that the achievements of seventeenth-century natural philosophy can easily be described as the ‘mechanization of the world-picture.’ That assumption licensed a story which took mechanization as self-evidently progressive and so in no need of further historical analysis. The clock-work world was triumphant and inevitably so. However, a close examination of one key group of natural philosophers working in England during the 1670s shows that their program necessarily incorporated souls and (...) spirits, attractions and congruities, within both their ontology and their epistemology. Any natural philosophical strategy which excluded spirits and sympathies from its world was condemned as tending to subversion and irreligion. This examination shows that the term ‘mechanical philosophy’ was a category given its meanings within local contexts and carries no universal sense separate from that accomplished by these natural philosophers. It also shows how the experimental praxis was compelled to treat souls and spirits, to produce them through experimental labor, and then to extend these experimentally developed entities throughout the cosmos, both social and natural. The development of mechanical philosophy cannot be used to explain the cognitive and social structure of this program, nor its success: instead, the historical setting of experimental work shows how a philosophy of matter and spirit was deliberately constructed by the end of the seventeenth century.

Although the importance, both historically and systematically, of the seventeenth century distinction between primary and secondary qualities is commonly recognised, there is no consensus on its exact nature. Apparently, one of the main difficulties in its interpretation is to tell the constitutive from the argumentative elements. In this paper, we focus on the primary-secondary quality distinctions drawn by Boyle and Locke. We criticise, more specifically, MacIntosh’s analysis of them. On the one hand, MacIntosh attributes too many different primary-secondary quality distinctions (...) to Boyle and Locke. On the other hand, he forbears to attribute a particular primary-secondary quality distinction to them, which, at least in the case of Boyle, differs genuinely from his main distinction between the mechanical affections of matter and all of matter’s other qualities.

Many philosophers have held that it is not possible to experience a spatial object, property, or relation except against the background of an intact awareness of a space that is somehow ‘absolute’. This paper challenges that claim, by analyzing in detail the case of a brain-damaged subject whose visual experiences seem to have violated this condition: spatial objects and properties were present in his visual experience, but space itself was not. I go on to suggest that phenomenological argumentation can give (...) us a kind of evidence about the nature of the mind even if this evidence is not absolutely incorrigible. (shrink)

How should we think about the role of visual spatial awareness in perception and perceptual knowledge? A common view, which finds a characteristic expression in Kant but has an intellectual heritage reaching back farther than that, is that an account of spatial awareness is fundamental to a theory of experience because spatiality is the defining characteristic of “outer sense”, of our perceptual awareness of how things are in the parts of the world that surround us. A natural counterpart to this (...) idea is to treat self-consciousness as residing in a kind of sense that is fundamentally “inner”, such as introspection or whatever else gives one privileged access to his own mental states as well as the proprioceptive and kinesthetic awareness of bodily position. This division is compatible, of course, with the idea that inner sense provides an awareness of a distinctive kind of “body space”, but it treats that as importantly different from the awareness of the worldly space around one. -/- In contrast to such a picture, this dissertation proposes an account of visual spatial awareness according to which it is no less a source of self-consciousness than of the awareness of the objects around us, and an account of self-awareness in which visual experience is essentially implicated. I begin by arguing that we should think of visual spatial awareness not as necessary for the individuation of visual sensations but rather as an essential element in the awareness of an experientially objective world. In the subsequent chapters, I argue that in being visually aware of the egocentric positions of the worldly objects around us we are often aware also of our own spatial locations with respect to them, and that the visual experience of the world around one and one’s own situation in it is often an essential component in the knowledge that a human agent will have of his own intentional actions.

The first half of this review article on Locke on primary and secondary qualities leads up to a fairly straightforward reading of what Locke says about the distinction in Essay II.viii, one that, in its general outlines, represents a sympathetic understanding of Locke’s discussion. The second half of the paper turns to consider a few of the ways in which interpreting Locke on primary and secondary qualities has proven more complicated. Here we take up what is sometimes called the Berkeleyan (...) interpretation of Locke, the understanding of Locke’s resemblance thesis, and Locke’s views of qualities and their relationship to powers.

Philosophers today have largely given up on the project of categorizing being. Aristotle’s ten categories now strike us as quaint, and no attempt to improve on that effort meets with much interest. Still, no one supposes that reality is smoothly distributed over space. The world at large comes in chunks, and there remains a widespread intuition, even among philosophers, that some of these chunks have a special sort of unity and persistence. These, we tend to suppose, are most truly agents (...) and subjects, and are what exist in the most proper sense of the term. We believe, in other words, in substances. (shrink)

It has long been recognized that unnecessary cruelty to animals was held to be morally wrong by many classical moralists and medieval scholastics, and was echoed repeatedly in the early-modern period, though not necessarily reflecting any particular concern for animals, but rather to indicate the supposed brutalizing effects on the human character. The prevalence of the more radical view that cruelty to animals was wrong regardless of human consequences has only been dealt with comparatively recently, in the pioneering work of (...) Keith Thomas with regard to early-modern England. Thomas suggested that a remarkably constant and coherent argument underpinned the bulk of pamphleteering and preaching against animal cruelty in the period; man was entitled to domesticate animals and kill them for food and clothing but not to cause them unnecessary suffering. While wild animals could be killed for food or in self-defence, and game and vermin could be hunted, it was deemed wrong to kill only for pleasure. While this position could be found among Protestants of many different persuasions, the particular focus of successive campaigners changed over time. Preceding the Civil War the attack was concentrated on cock-fighting, bear-baiting and the ill-treatment of domestic animals; in the later seventeenth century it broadened out to include the caging of wild birds, brutal methods of slaughter, hare-hunting and vivisection.

in The Cambridge Companion to Locke’s Essay, edited by Lex Newman. Cambridge: Cambridge University Press, 2007.

In a well-known paper, Reginald Jackson expresses a sentiment not uncommon among readers of Locke: “Among the merits of Locke’s Essay…not even the friendliest critic would number consistency.”2 This unflattering opinion of Locke is reiterated by Maurice Mandelbaum: “Under no circumstances can [Locke] be counted among the clearest and most consistent of philosophers.”3 The now familiar story is that there are innumerable inconsistencies and internal problems contained in Locke’s Essay. In fact, it is probably safe to say that there is (...) not another canonical, well-respected, and seminal philosopher whose work is so widely thought to be swarming with inconsistencies. I, however, do not think that the common, unflattering view of Locke is accurate as a general view of the Essay. But despite my wishes to the contrary, I do believe that Locke’s chapter ‘Of Identity and Diversity’ (2.27)4 leads to (at least) one intractable problem, a problem that is the subject of this paper.

In this thesis I argue that we should break with the dominant Kripkean tradition concerning natural kind terms and theoretical identity. I claim that there is just no interesting connection between the metaphysics and semantics of natural kind terms, and demonstrate this by constructing a version of descriptivism that is combined with the same metaphysics – that is, a nontrivial version of essentialism – found in Kripke, but which effectively avoids all of the standard criticisms. With my version of descriptivism (...) in place, I present what I take to be the most reasonable version of metaphysical essentialism, positing only what I call 'thin' essences. I claim that thin essences are perfectly adequate to underpin scientific realism, and moreover that they are sufficient to support the version of descriptivism developed here. In effect, what I offer here is an error theory of the Kripkean tradition: Kripke is right to think that there are interesting things to say about meaning and essence, but just wrong about what those things are. Thus whilst Kripke thinks that it is possible to make discoveries about the meanings of natural kind terms, I think, rather, that we make empirical discoveries that lead to revisions in meaning. Furthermore, whilst Kripke thinks there is a dichotomy between de re and de dicto necessity, and that theoretical identities are necessary de re, I think this distinction is both misleading and inaccurate, and that the necessity of theoretical identities is neither entirely de re nor entirely de dicto. By separating and insulating questions concerning meaning from questions concerning essence I show that whilst scientific discoveries are contingent and a posteriori, the definition of scientific terms are both necessary and a priori.

Seth Pringle-Pattison (233n1) observed that Locke “teaches a twofold mystery—in the first place, of the essence (‘for the powers or qualities that are observable by us are not the real essence of that substance, but depend upon it or flow from it’), and in the second place, of the substance itself (‘Besides, a man has no idea of substance in general, nor knows what substance is in itself.’ Bk. II.31.13).” In this paper, I’ll explain the relation between the two mysteries. (...) Our Rosetta Stone is Locke’s argument that we understand body and spirit equally well since we are ignorant of their underlying substances but we “have distinct clear Ideas of two primary Qualities, or Properties” (2.23.30) of each. I’ll show that he is working with a restricted notion of primary quality in this passage, but one that demonstrably falls under the kind defined in his chapter on primary and secondary qualities. According to Locke, the fundamental primary qualities of bodies flow from corporeal substances and the determinations of these fundamental qualities constitute real essences. Locke’s discussion can’t be understood without understanding the relevant scholastic background. In the first half of my paper, I’ll explain his argument as an idiosyncratic application of doctrines he learned and taught at Oxford. In the second half, I’ll use lessons from my interpretation of the argument to explain the relation that Locke believes obtains between a substance and its fundamental primary qualities, and then I’ll build upon that explanation to elucidate his general account (insofar as he has a general account) of the inherence of qualities in corporeal substances.

The ArgumentThis paper is a study of the role of language in scientific activity. It recommends that language be viewed as a community's means of patterning its affairs. Language represents where the boundaries of the community are and who is entitled to speak within it, and it displays the structures of authority in the community. Moreover, language precipitates the community's view of what the world is like, such that linguistic usages can be taken as referring to that world. Thus, language (...) connects on the one side to a community's practical life, and, on the other, to the reality on which it “reports.”The example treated is Robert Boyle's view of the language proper for experimental practice, and his arguments against the value and legitimacy of mathematical representations within the experimental community. Boyle argued that the use of mathematics was inappropriate because (i) it would restrict the number of potential participants; (ii) it would give rise to unwarranted expectations of the certainty and accuracy to be expected of real physical inquiries; (iii) it would suggest views of natural law and God's relations with the natural world which were incorrect and possibly dangerous; and because (iv) the world upon which the experimentalist operated was not such as was represented by mathematical idealizations. I try to establish that decision about the appropriate language for the experimental community was a moral choice. (shrink)

The notion of a “query” occurred in legal, medical, theological and scientific writings during the early modern period. Whereas the “questionary” (from c. 1400s) sought replies from within a doctrine (such as Galenic medicine), in the 1600s the query posed open-ended inquiries, seeking empirical information from travellers, explorers and others. During the 1660s in Britain, three versions of the query (and lists of queries) emerged. Distinctions need to be made between queries seeking information via observation and those asking for experimentation, (...) and between those aiming to keep theory to one side and those that framed theoretical conjectures. My examples are drawn from the work of the Royal Society of London (founded 1660) and from some of its leading members, especially Robert Boyle, Robert Hooke and Isaac Newton. (shrink)

Noting that the doctrine of the general resurrection attracted renewed attention after the Reformation, and after the atomist revival led to the displacement of traditional hylomorphism by alternative matter theories, this article surveys the ways in which the resurrection was discussed by leading natural philosophers in seventeenth‐century England. These include discussion of how bodily resurrection might be possible, what resurrected bodies will be like; as well as the nature of living conditions after the resurrection. It is indicated that the resurrection (...) seems to have played a much less prominent place in the writings of natural philosophers than the doctrine of the immortality of the soul, and other issues of natural theology. Reasons for this lack of prominence are tentatively offered, chiefly focusing on its unsuitability for combatting the perceived atheism of the time. It is hoped that this preliminary survey might inspire others to extend the survey, especially to cover Continental philosophers. (shrink)

This article proposes a new account of the relation between the sciences and common sense. A debate between Alfred North Whitehead and Arthur S. Eddington highlighted both the tendency of the natural sciences to repudiate commonsense conceptions of the world and the greater closeness of the human sciences to common sense. While analytic writers have mostly regarded these features as self-evident, I offer an explanation of them by appealing to Wilhelm Dilthey and the phenomenological tradition. Dilthey suggested that, whereas the (...) natural sciences could individuate their phenomena purely from empirical data, human sciences were compelled to refer to commonsense understanding in order to individuate mental phenomena. I apply this insight to episodes from the history of science, and use it to contrast the work of Alfred Schutz and Carl G. Hempel in philosophy of social and natural science. In the final section, I argue that Dilthey’s framework also offers resources to challenge present-day reductionism about mental phenomena. (shrink)

Ever since Hilary Putnam claimed that a realist philosophy is “the only philosophy that doesn’t make the success of science a miracle,” explanations for the success of science have proliferated in the philosophical literature (Putnam 1975, p. 73). Realists argue that the success of science, as exhibited by our ability to accurately predict and explain a wide range of phenomena, indicates that our theories have identified some of the underlying causal structures of the world (e.g., Boyd 1985, Ellis 1985, McMullin (...) 1984, Salmon 1984). Nonrealists counter that success cannot provide a warrant for belief in the truth of scientific theories because there have been successful theories in the past that are now believed to be false (Laudan 1981b). Instead, they offer a naturalized account whereby our theories are designed to be successful predictors and only those which fulfill this goal survive (Laudan 1987, van Fraassen, 1980). (shrink)
