ABSTRACTJohn Locke is famous for popularizing the method of the philosophical thought experiment in discussions of personal identity; the cases introduced in the second edition of An Essay Concerning Understanding are still employed by contemporary philosophers. Here I argue that Locke’s method is nonetheless importantly different from later efforts in ways that can help us better appreciate his larger projects. Rather than pumping the reader’s intuitions in support of his preferred account, Locke’s thought experiments serve to illustrate common errors in (...) assessments of identity that he sees as particularly prevalent and problematic. Locke defends his idea of ‘person’ otherwise, through what I call his ‘lived experiments’: observations about linguistic usage that serve to illustrate the term’s role in practical reasoning. I focus especially on Locke’s example of the forensic status of the madman. Examples like these do not, for Locke, demonstrate the intuitiveness of his analysis, but rather bolste... (shrink)

ABSTRACTJacques Rohault is often considered to be one of the most meticulous followers of Descartes. Despite this, Rohault’s natural philosophy lacks much of the metaphysical bulwark that typifies Cartesian treatises of the seventeenth century. Instead, Rohault’s work, as well as his popular weekly meetings, strongly emphasized rigorous observation and experimentation. Traditionally, this emphasis on experiment over metaphysics is seen as a pragmatic omission to avoid the perils associated with censorship and Cartesian metaphysics. However, I find that the lack of explicit (...) metaphysics has real consequences that play out in the role Rohault assigns to experimentation. To show this, I highlight several areas where he adopts a broad experimental methodology even though Descartes explicitly rejects the relevancy of experiment on metaphysical topics. I place special emphasis Rohault’s extensive experiment on the void. In short, Rohault’s experimentation was designed to prove, through experimental mea... (shrink)

Contemporary experimental philosophers sometimes use versions of an argument from the history of philosophy to defend the claim that what they do is philosophy. Although experimental philosophers conduct surveys and carry out what appear to be experiments in psychology, making them methodologically different from most analytic philosophers working today, techniques like theirs were not out of the ordinary in the philosophy of the past, early modern philosophy in particular. Or so some of them argue. This paper disputes the argument, citing (...) important differences between early modern philosopher-scientists – Descartes, Hobbes and Boyle – and their supposed modern counterparts. Although there is some continuity between early modern philosopher-scientists and the contemporary experimentalists, it is mostly a continuity of interest in empirically informed philosophy, not a distinctively experimental philosophy.

This paper argues that the activist, feminist and pragmatist Jane Addams was an experimental philosopher. To defend this claim, I argue for capacious notions of both philosophical pragmatism and experimental philosophy. I begin in Section 2 with a new defence of Rose and Danks’ [‘In Defense of a Broad Conception of Experimental Philosophy’. Metaphilosophy 44, no. 4 : 512–32] argument in favour of a broad conception of experimental philosophy. Koopman [‘Pragmatist Resources for Experimental Philosophy: Inquiry in Place of Intuition’. Journal (...) of Speculative Philosophy 26, no. 1 : 1–24] argues that many twentieth-century American pragmatists can make important contributions to contemporary experimental philosophy. In Section 3, I argue that while this may be true, it is also true that under the broad conception, many of the pragmatists just were experimental philosophers. In Section 4, I argue that as a pragmatist philosopher in her own right, Jane... (shrink)

Scientific realism does not view theoretical terms as mere instruments of experimental predictions; it grants referential status to natural kind terms with 'epistemic access' and view scientific theories and terms as corresponding to physical phenomena and entities which exist independently of observation, and as thereby being the source of objective -approximate and not absolute- knowledge of the physical realm. As a result, scientific realism is accused of ontologising the unobservables. Against this charge, scientific realism posits the idea of the dialectical (...) relation between theoretical terms referring to the unobservables and scientific methods. The second argument made by realism is the ‘no miracle’ thesis. These arguments stand challenged by the Copenhagen interpretation of quantum mechanics. The aim of the paper is to examine the relevance of the two arguments of scientific realism in countering the idea that the existence of quantum states in the microphysical world renders realism obsolete.

Resumen: Ante las críticas insistentes a la distinción entre el empirismo y el racionalismo, se han propuesto alternativas para comprender de manera más adecuada el quehacer de los filósofos modernos. Entre ellas está la distinción entre filosofía especulativa y experimental. Intentaré evaluar la validez de esta distinción para la filosofía moral experimental del siglo XVIII y, en particular, para la propuesta de Hume. Mostraré que si la distinción se entiende en términos excluyentes, resulta inapropiada porque el mismo Hume plantea que (...) la especulación es lo que define a la filosofía. Además, antes que considerarlas como excluyentes, el filósofo escocés propone una conciliación entre la práctica de la experimentación y la teorización. Por último, sostendré que aquello que Hume considera como “falsa filosofía” no puede entenderse como sinónimo de filosofía especulativa.: A persistent criticism of the distinction between empiricism and ra-tionalism has provoked the emergence of new distinctions in order to under-stand modern philosophy in a more adequate way. One of those distinctions is that between speculative and experimental philosophy. My aim is to evalu-ate the validity of this distinction for eighteenth-century experimental moral philosophy in general and for Hume’s thought in particular. I will show that if this distinction is understood in exclusive terms, then it cannot be adequate because Hume himself states that speculation is what defines philoso-phy. Hume also proposes a reconciliation between experimental practice and theoretical activity instead of considering that they are mutually exclusive. Finally, I will make clear that what Hume condemns as “false philosophy” is not a synonym for speculative philosophy. (shrink)

The lasting effects of the debate over canon-formation during the 1980s affected the whole field of Humanities, which became increasingly engaged in interrogating the origin and function of the Western canon. In philosophy, a great deal of criticism was, as a result, directed at the traditional narrative of seventeenth-and eighteenth-century philosophies—a critique informed by postcolonialism as well as feminist historiography. D. F. Norton, L. Loeb and many others1 attempted to demonstrate the weaknesses of the tripartite division between rationalism, empiricism and (...) critical philosophy.2 As time went on, symptoms of dissatisfaction with what has...

The conception of René Descartes as the arch-rationalist has been sufficiently exploded in recent literature; however, there is still a large lacuna in our understanding of how empirical research and experimentation fits within his philosophy. My dissertation is directed at addressing just this problem. I contend that Descartes’ famed method is not a singular monolith but instead two interdependent methods: one directed at metaphysical and epistemological truth, while the other directed at empirical questions and contingent facts of the world. I (...) claim there is evidence for this position not only in his actual scientific practice, but also in the rhetorical structure of the Discourse on Method and the Principles of Philosophy. In exploring the empirical side of Descartes’ method, I show how his unusual system produces a system of experiment designed to serve both as a discovery and verification tool at the same time. As a further application of my interpretation, I argue that the Passions of the Soul and Descartes’ ethical theory expressed in his correspondence must also be seen as part of his two-fold methodology. Instead of attempting to cast Descartes as a virtue ethicist or deontologist, as is normally done, I emphasize that Descartes’ ethics is centered on the mind-body union, and therefore, includes an empirical element as well. The end result is an ethics that requires a detailed study of mechanics, anatomy, physics, as well as medicine. Lastly, I show how this methodology can help us understand the works of some of his early followers: Claude Gadroys and Jacques Rohault. Both of these philosophers not only serve to ground my interpretation, but also to highlight aspects of Cartesian that have often been passed over. I show how the experimentalism of Jacques Rohault goes beyond the epistemological boundaries set up by Descartes, as signifies a new direction that will ultimately eclipse the Cartesian school of thought. In the case of Claude Gadroys, I present a concrete example of the exploitation of the over generality of Cartesian principles. In so doing, I show that while Descartes’ experimentalism was intended to rule out the possibility of occult causes, he in fact created a system that allowed for them, only under a different guise.

Experimental philosophy (or “x-phi”) is a way of doing philosophy. It is “traditional” philosophy, but with a little something extra: In addition to the expected philosophical arguments and engagement, x-phi involves the use of empirical methods to test the empirical claims that arise. This extra bit strikes some as a new, perhaps radical, addition to philosophical practice. We don’t think so. As this chapter will show, empirical claims have been common across the history of Western philosophy, as have appeals to (...) empirical observation in attempting to support or subvert these claims. While conceptions of philosophy have changed over time, across these changes we find philosophers employing empirical methods in pursuing their philosophical questions. Our primary aim in this chapter is to illustrate this fact. We begin by discussing the relevance of history to experimental philosophy (Section 2), then offer a necessarily condensed and highly selective history of empirical work in Western philosophy, ranging from the ancients (Section 3), to the early moderns (Section 4), to the late moderns (Section 5), and on to the present (Section 6).

This thesis investigates Hume’s philosophy of external existence in relation to, and within the context of, his philosophy of scepticism. In his two main works on metaphysics – A Treatise of Human Nature (1739–40) and the first Enquiry (first ed. 1748) – Hume encounters a predicament pertaining to the unreflective, ‘vulgar’ attribution of external existence to mental perceptions and the ‘philosophical’ distinction between perceptions and objects. I argue that we should understand this predicament as follows: the vulgar opinion is our (...) natural and default belief for Hume, but causal reasoning reveals it to be false, and the philosophical alternative is a confabulation that we cannot permanently believe and is devoid of justification. Hume uses the fact that we cannot have a satisfactory account of belief in external existence as a sceptical consideration to motivate his wider philosophical scepticism. Hume’s response to his predicament about external existence is found in the context of his confrontation with other sceptical worries (Treatise 1.4.7 and Enquiry 12), in which Hume also reflects generally on the nature and implications of scepticism. I argue that we should characterise Hume’s position as residually sceptical. This means that, while Hume accepts the unanswerability of some sceptical problems, he denies that it is possible to eradicate all belief as a result (and denies that it is practically useful to even try) and instead uses sceptical problems as a motivation to adopt a moderately sceptical position. While we inevitably return to entertaining the vulgar belief, there is no solution to the sceptical predicament; Hume does not endorse the vulgar belief, or the philosophical system, or indeed any alternative system of the external world that might extinguish the predicament. Sceptical doubt, for Hume, does not derail intellectual pursuits, but rather modifies our attitudes in those very pursuits. (shrink)

In the last few decades, the historiographical categories rationalism and empiricism have been criticized for their limitations to explain the complex positions and the links held by the philosophers tradiotnally attached to them. This narrative was firstly conceived by Kantian German historians and began to become standard at the turn of the twentieh century. Nonetheless, nineteenth-century French historiography developed other narratives by which early modern philosophers were classified according to alternative criteria. In the first edition of Histoire comparée des systémes (...) de philosophie (1804), Joseph-Marie Degérando distinguishes three first-order early modern schools founded by Bacon, Descartes and Leibniz, respectively. Degérando introduces the empiricism and rationalism distinction as one among others, and not as the fundamental one. In addition, he separates empiricism from experimental philosophy. The last one, along with speculative philosophy, is said to conciliate senses and reason. As a result, this account offers philosophical groupings different from those constructed by the standard narrative. Furthermore, it draws on labels and classification criteria which were part of the early modern philosophical discourse. (shrink)

We look at some interesting and important episodes in the life of early modern Epicureanism, focusing on natural philosophy. We begin with two early moderns who had a great deal to say about ancient Epicureanism: Pierre Gassendi and Ralph Cudworth. Looking at how Gassendi and Cudworth conceived of Epicureanism gives us a sense of what the early moderns considered important in the ancient tradition. It also points us towards three main themes of early modern Epicureanism in natural philosophy, which we (...) then discuss at greater length: atomism, materialism about the mind or soul, and the denial of providence, which was often accompanied by deflationary explanations of religious belief.
