Illegitimacy in a historic, single community at Penrith, Cumbria (1557–1812), has been studied using aggregative analysis, family reconstitution and time series analysis. This population was living under extreme conditions of hardship. Long, medium and short wavelength cycles in the rate of illegitimacy have been identified by time series analysis; each represents a different response to social and economic pressures. In a complex interaction of events, the peaks of the cycles in wheat prices were associated with rises in adult mortality which (...) promoted an influx of migrants and a concomitant rise in illegitimacy. The association between immigration and illegitimacy was particularly noticeable after the mortality crises of the late sixteenth and early seventeenth centuries. Children of immigrant families also tended to produce illegitimate offspring. Native and immigrant families responded differently to extrinsic fluctuations, and variations in their reproductive behaviour were probably related to access to resources. (shrink)

Sex-biased investment in children has been explored in a historic population in northern England, 1600 to 1800, following a family reconstitution study. An examination of the wills and other available data identified three social groups: the elite, tradesmen, and subsistence farmers. The community lived under marginal conditions with poor and fluctuating levels of nutrition; infant and child mortalities were high. Clear differences were found between the social groups, and it is suggested that the elite wetnursed their daughters whereas the elite (...) mother breast-fed her sons for only a short period and introduced supplementary feeding early. The wives of the tradesmen probably breast-fed both sexes for the same length of time. Subsistence farmers may have weaned their sons earlier than daughters. The results are discussed in terms of possible differences in investment strategies. The investment strategy of the elite group was probably male-biased but may, in practice, have favored the female offspring. (shrink)

Leibniz's mill argument in 'Monadology' 17 is a well-known but puzzling argument against materialism about the mind. I approach the mill argument by considering other places where Leibniz gave similar arguments, using the same example of the machinery of a mill and reaching the same anti-materialist conclusion. In a 1702 letter to Bayle, Leibniz gave a mill argument that moves from his definition of perception (as the expression of a multitude by a simple) to the anti-materialist conclusion. Soon afterwards, in (...) the Preface to the New Essays, Leibniz gave a different mill argument. That argument depends upon there being no arbitrary and inexplicable connections in nature, because God would not create such things. Later, in the 'Monadology', Leibniz again used the mill example in arguing against materialism. That passage too, I argue, uses an argument from inexplicability rather than from Leibniz's definition of perception. (shrink)

This paper discusses the materialist views of Margaret Cavendish, focusing on the relationships between her views and those of two of her contemporaries, Thomas Hobbes and Henry More. It argues for two main claims. First, Cavendish's views sit, often rather neatly, between those of Hobbes and More. She agreed with Hobbes on some issues and More on others, while carving out a distinctive alternative view. Secondly, the exchange between Hobbes, More, and Cavendish illustrates a more general puzzle about just what (...) divided materialists from their opponents. Seemingly straightforward disagreements about whether incorporeal substances exist turn out to be more complex ones in which the nature of those things is disputed at the same time as their existence.

In this article I shall concern myself with the question ‘Is some type of justification required in order for belief in God to be rational?’ Many philosophers and theologians in the past would have responded affirmatively to this question. However, in our own day, there are those who maintain that natural theology in any form is not necessary. This is because of the rise of a different understanding of the nature of religious belief. Unlike what most people in the past (...) thought, religious belief is not in any sense arrived at or inferred on the basis of other known propositions. On the contrary, belief in God is taken to be as basic as a person's belief in the existence of himself, of the chair in which he is sitting, or the past. The old view that there must be a justification of religious belief, whether known or unknown, is held to be mistaken. One of the most outspoken advocates of this view is Alvin Plantinga. According to Plantinga the mature theist ought not to accept belief in God as a conclusion from other things he believes. Rather, he should accept it as basic, as a part of the bedrock of his noetic structure. ‘The mature theist commits himself to belief in God; this means that he accepts belief in God as basic.’.

In the early years of the eighteenth century Leibniz had several interactions with John Toland. These included, from 1702 to 1704, discussions of materialism. Those discussions culminated with the consideration of Toland's 1704 Letters to Serena, where Toland argued that matter is necessarily active. In this paper I argue for two main theses about this exchange and its consequences for our wider understanding. The first is that, despite many claims that Toland was at the time of Letters to Serena a (...) Spinozist, we can make better sense of him as a sort of Hobbesian materialist. The second main point concerns reasons for materialism, and in particular a story Locke tells in the Essay about materialists' motives. Toland defends his materialism by arguing that matter is active, and argues that matter is active by using a conceivability argument. But this is not the crude conceivability argument that Locke suggests motivates materialists. This (together with reflecting on some of Hobbes's arguments) suggests that we might well tell a Lockean story about reasons for early modern materialism, but not Locke's story. (shrink)

The notion of signification is an important part of Hobbes's philosophy of language. It also has broader relevance, as Hobbes argues that key terms used by his opponents are insignificant. However Hobbes's talk about names' signification is puzzling, as he appears to have advocated conflicting views. This paper argues that Hobbes endorsed two different views of names' signification in two different contexts. When stating his theoretical views about signification, Hobbes claimed that names signify ideas. Elsewhere he talked as if words (...) signified the things they named. Seeing this does not just resolve a puzzle about Hobbes's statements about signification. It also helps us to understand how Hobbes's arguments about insignificant speech work. With one important exception, they depend on the view that names signify things, not on Hobbes's stated theory that words signify ideas. The paper concludes by discussing whether arguments about insignificant speech can provide independent support for Hobbes's views about other issues, such as materialism. (shrink)

I consider Leibniz's thoughts about Hobbes's materialism, focusing on his less-discussed later thoughts about the topic. Leibniz understood Hobbes to have argued for his materialism from his imagistic theory of ideas. Leibniz offered several criticisms of this argument and the resulting materialism itself. Several of these criticisms occur in texts in which Leibniz was engaging with the generation of British philosophers after Hobbes. Of particular interest is Leibniz's correspondence with Damaris Masham. Leibniz may have been trying to communicate with Locke, (...) but ended up discussing Masham's version of the argument for materialism that Leibniz attributed to Hobbes. (shrink)

Hobbes denies in Leviathan that we have an idea of God. He does think, though, that God exists, and does not even deny that we can think about God, even though he says we have no idea of God. There is, Hobbes thinks, another cognitive mechanism by means of which we can think about God. That mechanism allows us only to think a few things about God though. This constrains what Hobbes can say about our knowledge of God, and grounds (...) his belief in a fairly strong version of the thesis that God is incomprehensible. (shrink)

I argue that Hobbes isn't really a materialist in the early 1640s (in, e.g., the Third Objections to Descartes's Meditations). That is, he doesn't assert that bodies are the only substances. However, he does think that bodies are the only substances we can think about using imagistic ideas.

Debates in Modern Philosophy: Essential Readings and Contemporary Responses provides an in-depth, engaging introduction to important issues in modern philosophy. It presents 13 key interpretive debates to students, and ranges in coverage from Descartes' Meditations to Kant's Critique of Pure Reason. -/- Debates include: -/- Did Descartes have a developed and consistent view about how the mind interacts with the body? Was Leibniz an idealist, or did he believe in corporeal substances? What is Locke's theory of personal identity? Could there (...) be a Berkeleian metaphysics without God? Did Hume believe in causal powers? What is Kant's transcendental idealism? -/- Each of the thirteen debates consists of a well known article or book chapter from a living philosopher, followed by a new response from a different scholar, specially commissioned for this volume. Every debate is prefaced by an introduction written for those coming upon the debates for the first time and followed by an annotated list for further reading. The volume starts with an introduction that explains the importance and relevance of the modern period and its key debates to philosophy and ends with a glossary that covers terms from both the modern period and the study of the history of philosophy in general. -/- Debates in Modern Philosophy will help students evaluate different interpretations of key texts from modern philosophy, and provide a model for constructing their own positions in these debates.

Language was central to Hobbes's understanding of human beings and their mental abilities, and criticism of other philosophers' uses of language became a favorite critical tool for him. This paper connects Hobbes's theories about language to his criticisms of others' language, examining Hobbes's theories of propositions and truth, and how they relate to his claims that various sorts of proposition are absurd. It considers whether Hobbes in fact means anything more by 'absurd' than 'false'. And it pays particular attention to (...) Hobbes's categorization of causes of absurdity and of types of incoherent proposition, arguing that Hobbes's approach is only loosely related to later discussions of category mistakes. (shrink)

Early modern debates about the nature of matter interacted with debates about whether matter could think. In particular, some philosophers (e.g., Cudworth and Leibniz) objected to materialism about the human mind on the grounds that matter is passive, thinking things are active, and one cannot make an active thing out of passive material. This paper begins by looking at two seventeenth-century materialist views (Hobbes’s, and one suggested but not endorsed by Locke) before considering that objection (which I call here the (...) Activity Argument). In discussion, I note that several philosophers of the time believed that matter was active. That view opens up a possible response to the Activity Argument. The paper concludes by looking at the views of two materialists of the time who also believed that matter was active, Toland and Cavendish. (shrink)

Leibniz frequently uses the notion of expression, but it is not easy to see just how he understood that relation. This paper focuses on the particular case of the expression of God, which is prominent in the 'Discourse on Metaphysics'. The treatment of expression there suggests several questions. Which substances did Leibniz believe expressed God? Why did Leibniz believe those substances expressed God? And did he believe that all substances expressed God in the same way and for the same reasons? (...) In answering those questions the paper distinguishes two views about expression in the 'Discourse', considers Leibniz's reasons for holding that substances express their causes, and argues that Leibniz's views about emanative causation are important for understanding the unity of his apparently distinct views here. The paper concludes by looking briefly at how the 'Discourse' fits into the evolution of Leibniz's views on this issue over time. (shrink)

In this article, we explore the ethical issues related to the reporting of suspected abuse or neglect in research involving children. Ethical dilemmas related to reporting child maltreatment are often complex because the rights of children and their adult caregivers may conflict and determinations of abuse or neglect are socially constructed judgments that depend on particular circumstances. We argue that when reporting is legally mandated, investigators must follow the law and report their suspicions to Child Protective Services. When reporting is (...) not legally mandated, investigators still have an ethical obligation to report to help prevent additional maltreatment and allow children to obtain access to services needed to recover from abuse or neglect. We also argue that investigators should include plans and procedures in the research protocol for making reports and training research staff in recognising evidence of child abuse or neglect. Although investigators should report evidence of abuse or neglect that is discovered incidentally, they have no mandate to actively search for such evidence when it is not related to the study’s objectives. Investigators should also inform parents and children about their obligations to report suspected abuse or neglect. (shrink)

The effect of nutrition on fertility and its contribution thereby to population dynamics are assessed in three social groups (elite, tradesmen and subsistence) in a marginal, pre-industrial population in northern England. This community was particularly susceptible to fluctuations in the price of grains, which formed their basic foodstuff. The subsistence class, who formed the largest part of the population, had low levels of fertility and small family sizes, but women from all social groups had a characteristic and marked subfecundity in (...) the early part of their reproductive lives. The health and nutrition of the mother during pregnancy was the most important factor in determining fertility and neonatal mortality. Inadequate nutrition had many subtle effects on reproduction which interacted to produce a complex web of events. A population boom occurred during the second half of the 18th century; fertility did not change but there was a marked improvement in infant mortality and it is suggested that the steadily improving nutritional standards of the population, particularly during crucial periods in pregnancy (i.e. the last trimester), probably made the biggest contribution to the improvement in infant mortality and so was probably the major factor in triggering the boom.

Thomas Hobbes (1588-1679), whose current reputation rests largely on his political philosophy, was a thinker with wide ranging interests. In philosophy, he defended a range of materialist, nominalist, and empiricist views against Cartesian and Aristotelian alternatives. In physics, his work was influential on Leibniz, and lead him into disputes with Boyle and the experimentalists of the early Royal Society. In history, he translated Thucydides's History of the Peloponnesian War into English, and later wrote his own history of the Long Parliament. (...) In mathematics he was less successful, and is best remembered for his repeated unsuccessful attempts to square the circle. But despite that, Hobbes was a serious and prominent participant in the intellectual life of his time. (shrink)

When this work was first published in 1960, it immediately filled a void in Kantian scholarship. It was the first study entirely devoted to Kant's _Critique of Practical Reason_ and by far the most substantial commentary on it ever written. This landmark in Western philosophical literature remains an indispensable aid to a complete understanding of Kant's philosophy for students and scholars alike. This _Critique_ is the only writing in which Kant weaves his thoughts on practical reason into a unified argument. (...) Lewis White Beck offers a classic examination of this argument and expertly places it in the context of Kant's philosophy and of the moral philosophy of the eighteenth century. (shrink)

Preoccupation with LTP as a putative memory mechanism may have retarded the consideration of pathological modulation of synaptic plasticity in clinical disorders where memory dysfunction is not a primary feature. Encouraged by Shors & Matzel's review, we consider the relationship between stress, synaptic plasticity, and depressive disorder.

This dissertation discusses the work of Thomas Hobbes, and has two main themes. The first is Hobbes's materialism, and the second is Hobbes's relationships to other philosophers, in particular his place in the mechanist movement that is said to have replaced Aristotelianism as the dominant philosophy in the seventeenth century. -/- I argue that Hobbes does not, for most of his career, believe the general materialist view that bodies are the only substances. He believes, rather, that ideas, which are our (...) main mechanism for thinking about the world, allow us to understand many bodies, but not to understand every thing we recognize to exist. The incomprehensible things include God---and, early in Hobbes's career, the human mind. Discussing materialism and our knowledge of God leads me to engage with the debate over Hobbes's alleged atheism. I argue that the evidence for Hobbes's atheism is weak at best. Hobbes is a sincere theist, though his view is sometimes unusual. -/- My discussion of Hobbes's relationships to other philosophers has three parts. In chapter five I argue that Hobbes's views about method are in important ways similar to Zabarella's. In chapter six I look at Hobbes's rejection of the view, held by some scholastic Aristotelians, that accidents can sometimes exist without inhering in substances. Thus we see two sides of Hobbes's interaction with the Aristotelian tradition. Sometimes that interaction is just rejection, but at other times Hobbes takes over views from that tradition. Then in chapter seven I consider whether, and in what sense, Hobbes is a mechanist. I argue that the narrative of mechanism and Aristotelianism is a less powerful explanation than it has seemed to some to be, because it is hard to see what mechanists have in common. (shrink)

The exogenous cycles and population dynamics of the community at Penrith, Cumbria, England, have been studied (1557-1812) using aggregative analysis, family reconstitution and time series analysis. This community was living under marginal conditions for the first 200 years and the evidence presented is of a homeostatic regime where famine, malnutrition and epidemic disease acted to regulate the balance between resources and population size. This provides an ideal historic population for an investigation of the direct and indirect effects of malnutrition. Throughout (...) the period studied, a short wavelength oscillation in grain prices was apparently the major external factor that drove exogenous cycles in mortality, birth rate, and migration. In particular, the different responses of children to variations in food supply are emphasised; fluctuations in poor nutrition correlated significantly with the variations in mortality rates for infants (probably indirectly during pregnancy and directly during the first year of life) and for young children (via susceptibility to lethal infectious diseases). Migratory movements contributed to the maintenance of homeostasis in the population dynamics. A medium wavelength cycle in low winter temperatures was associated with a rise in adult mortality which, in turn, promoted an influx of migrants into this saturated habitat. A model incorporating these interacting associations between vital events and exogenous cycles is presented: grain prices were an important density-dependent factor and constituted the major component of the negative feedback of this population and drove the exogenous, short wavelength mortality cycles. Cycles of births and immigration provide a positive feedback for the build-up of susceptibles and the initiation of smallpox epidemics and increased population size. (shrink)

My dissertation consists of two main parts. In the first part, I begin by assuming the plausibility of the libertarian thesis that agents sometimes could have done otherwise than they did given the very same history of the world. In light of this assumption, I undertake to develop a model of agency which does not employ the concept of agent-causation. My agency theory is developed in three main stages: I suggest that any agency theory must satisfy four desiderata: It must (...) adequately account for the freedom and responsibility of human agents. It must provide an adequate answer to the question of what distinguishes human actions from mere happenings. It must adequately account for the epistemological fact that human agents have an immediate and nonobservational awareness of their actions. It should have the support of a respectable philosophical tradition. I argue that agent-causation provides a theory of agency which fails adequately to satisfy these four desiderata. I claim both that human actions are uncaused exercisings by agents of their powers and that human agents typically act for reasons. I maintain that the central issue dividing agency theorists and nonagency theorists is whether reasons for performing actions cause the latter. I maintain that the sense of 'because' in 'I did x because...' is not causal in nature, but teleological. ;Having developed my model of agency, in the second part of my dissertation I investigate what are some of the paradigmatic actions human agents perform. I claim that bodily actions, such as moving an arm, are psychological in nature. Essential to my argument is the concept of a body-image. A normal agent 'feels' as if she is present in her physical arm. The way a normal agent feels is revealed in the case of a phantom limb. The subject of a phantom arm feels as if her amputated physical arm is still there and she can move while feeling armishly. I maintain that the bodily action of moving an arm is the agent's movement as a psychological arm-image of her physical arm, whether the physical arm is present or not. (shrink)

This chapter considers Ralph Cudworth as a philosophical critic of Hobbes. Cudworth saw Hobbes as a representative of the three views he was attacking: atheism, determinism, and the denial that morality is eternal and immutable. Moreover, he did not just criticize Hobbes by assuming that a general critique of those views applied to Hobbes’s particular case. Rather, he singled out Hobbes, often by quoting him, and argued against the distinctively Hobbesian positions he had identified. In this chapter I look at (...) Cudworth as a critic of Hobbes in two of the three central areas, atheism and ethics, focusing on passages where we see him explicitly picking out Hobbes. (shrink)

This paper discusses two aspects of Larry May's book Limiting Leviathan. First it discusses a passage in Leviathan, to which May draws attention, in which Hobbes connects obligation to "that, which in the disputations of scholars is called absurdity". Secondly it looks at the book's discussion of Hobbes and pacifist attitudes, with reference to Hobbes's contemporary critic John Eachard.

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.

I discuss Hume's views about whether simplicity and generality are positive features of explanations. In criticizing Hobbes and others who base their systems of morality on self interest, Hume diagnoses their errors as resulting from a "love of simplicity". These worries about whether simplicity is a positive feature of explanations emerge in Hume's thinking over time. But Hume does not completely reject the idea that it's good to seek simple explanations. What Hume thinks we need is good judgment about when (...) we are going too far in our search for simple explanations. These worries about simplicity are not unique to Hume. We can see versions of them in the work of Hutcheson, Smith, and Reid. (shrink)

Hobbes repeatedly expressed concerns about moral and political language, e.g., about the bad consequences of various uses and misuses of language. He did not simply focus on the consequences though. He also attempted to understand the problems, using the central semantic notion in his philosophy of language, signification. Hobbes, in both the Elements of Law and Leviathan, argues that a wide variety of terms – including ‘good’, ‘bad’, and the names of virtues and vices – have a double and inconstant (...) signification. This paper explores and explains that theory of Hobbes's. (In the course of the discussion, two other interpretations of Hobbes's claims are discussed: Pettit’s discussion in terms of indexicals, and Alexandra’s in terms of sense and reference.) This phenomenon is, Hobbes thinks, pervasive in our use of moral and political language. Indeed he says his analysis applies to all “names of such things as affect us, that is, which please, and displease us” (Leviathan 4.24), which seems a very broad category indeed. This inconstancy of signification has considerable potential to cause confusion and conflict. Given those practical consequences, it is of some importance for Hobbes to find a solution to this problem. The paper examines several possible Hobbesian solutions to the problem. There is, however, reason to think that these suggested solutions cannot completely solve the problem. The paper concludes, then, by arguing that double and inconstant signification would always be a danger, even in a properly constituted Hobbesian commonwealth. (shrink)

Thomas Hobbes was, rather famously, a nominalist. The core of that nominalism is the belief that the only universal things are universal names: there are no universal objects, or universal ideas. This paper looks at what Hobbes's views about universal names were, how they evolved over time, and how Hobbes argued for them. The remainder of the paper considers two objections to Hobbes's view: a criticism made by several of Hobbes's contemporaries, that Hobbes's view could not account for people saying (...) the same thing in different languages; and a more recently popular criticism of Hobbes, that his nominalism's reliance on similarity implicitly (and inconsistently) involves reliance on a universal.

This paper investigates Locke’s views about materialism, by looking at the discussion in Essay IV.x. There Locke---after giving a cosmological argument for the existence of God---argues that God could not be material, and that matter alone could never produce thought. In discussing the chapter, I pay particular attention to some comparisons between Locke’s position and those of two other seventeenth-century philosophers, René Descartes and Ralph Cudworth. -/- Making use of those comparisons, I argue for two main claims. The first is (...) that the important argument of Essay IV.x.10 is fundamentally an argument about the causation of perfections. Indeed, Locke gives multiple such arguments in the chapter. My second main claim is that my proposed reading of IV.x is not merely consistent with what Locke says elsewhere about superaddition, but also provides reasons to favor a particular understanding of what superaddition is.
