In this paper, I consider Isaac Newton’s fevered accusation that John Locke is a ‘Hobbist.’ I suggest a number of ways in which Locke’s account of the mind–body relation could plausibly be construed as Hobbesian. Whereas Newton conceives of the human mind as an immaterial substance and venerates it as a finite image of the Divine Mind, I argue that Locke utterly deflates the religious, ethical, and metaphysical significance of an immaterial soul. Even stronger, I contend that there is good (...) reason to suspect that Locke is a crypto-materialist, at least with respect to human beings, and in this respect, could reasonably be labeled a ‘Hobbist.’.

David Hume has traditionally been assumed to be a soft determinist or compatibilist, at least in the ‘reconciling project’ that he presents in Section 8 of the first Enquiry, entitled ‘Of liberty and necessity.’ Indeed, in encyclopedias and textbooks of Philosophy he is standardly taken to be one of the paradigm compatibilists, rivalled in significance only by Hobbes within the tradition passed down through Locke, Mill, Schlick and Ayer to recent writers such as Dennett and Frankfurt. Many Hume scholars also (...) concur in viewing him as a determinist, for example Norman Kemp Smith, Barry Stroud, A. J. Ayer, Paul Russell Don Garrett, Terence Penelhum, George Botterill, John Bricke, and John Wright. My main purpose in this paper will be to provide the evidence to substantiate this traditional interpretation, which has hitherto been widely assumed rather than defended. In the absence of such a defence, the consensus has been left open to challenge, most notably in a recent paper and a subsequent book by James Harris, who boldly claims that Hume ‘does not subscribe to determinism of any kind, whether Hobbesian or merely nomological.’.

The paper focuses on the reception of Priestley in Germany, which is remarkable for the huge and assiduous interest it raised in different philosophical milieus. Priestley’s dynamical conception of matter, his explanation of the functioning of the brain, and of the production of material ideas are at the basis of the new form of materialism that develops in Germany in the late 1770s, and which differs completely from the model of mechanical materialism Germany was used to in earlier decades. Indeed, (...) the German reception of Priestley’s ideas begins surprisingly early, just one year after the publication of his edition of Hartley’s Observations on Man (1775), and traverses the two final decades of the eighteenth century with a considerable number of reviews and references in the main philosophical journals and works of the time. In 1778, his introduction to the Observations was translated into German and presented in the form of a manifesto of a new materialistic philosophy compatible with the claims of morals and religion. Within a few years, Priestley became the unavoidable reference point for the most relevant theological and philosophical discussions concerning the nature of matter and spirits, the place of God, the possibility of human freedom, and the legitimacy of free thinking.

In the past, experts have disagreed about whether Samuel Clarke accepted the idea that gravity is a power superadded to matter by God. Most scholars now agree that Clarke did not support superaddition. But the argumentation employed by Clarke to reject superaddition has not been studied before in detail. In this paper, I explicate Clarke's argumentation by relating it to an important discussion about the possibility of superadded gravity in the Clarke-Collins correspondence. I examine Clarke's responses to Collins and draw (...) on his other works to reconstruct Clarke's reasons for rejecting superadded gravity. (shrink)

Most of the reports on synthetic biology include not only familiar topics like biosafety and biosecurity but also a chapter on ‘ethical concerns’; a variety of diffuse topics that are interrelated in some way or another. This article deals with these ‘ethical concerns’. In particular it addresses issues such as the intrinsic value of life and how to deal with ‘artificial life’, and the fear that synthetic biologists are tampering with nature or playing God. Its aim is to analyse what (...) exactly is the nature of the concerns and what rationale may lie behind them. The analysis concludes that the above-mentioned worries do not give genuine cause for serious concern. In the best possible way they are interpreted as slippery slope arguments, yet arguments of this type need to be handled with care. It is argued that although we are urged to be especially vigilant we do not have sufficiently cogent reasons to assume that synthetic biology will cause such fundamental hazards as to warrant restricting or refraining from research in this field.

First published Sat Apr 5, 2003; most recent substantive revision Wed Aug 22, 2018. -/- Samuel Clarke (1675–1729) was the most influential British philosopher in the generation between Locke and Berkeley. His philosophical interests were mostly in metaphysics, theology, and ethics.

The focus of this paper is a fascinating but hitherto unstudied 1742 manuscript treatise by Johannes Daniel Schlichting (1705–1765) titled “Sapientiæ Problema” that contains something extremely rare in the mid-eighteenth century: a full-blown speculative cosmogony. As this article reveals, Schlichting developed a distinctive vital liquid matter in an effort to account for the generation of all natural bodies and combat the stamina-based theories that were dominant in his day. He hoped that his treatise would be published in the Philosophical Transactions (...) of the Royal Society, but an accompanying abridgment by the FRS Henry Baker (1698–1774) strongly implies that Schlichting’s speculative bent and desire to divulge causal explanations were unacceptable to the Englishman and generally ill-suited to the intellectual climate of mid-century England.

The nature of the relationship between mind and body is one of the greatest remaining mysteries. As such, the historical origin of the current dominant belief that mind is a function of the brain takes on especial significance. In this article I aim to explore and explain how and why this belief emerged in early 19th-century Britain. Between 1815 and 1819 two brain-based physiologies of mind were the subject of controversy and debate in Britain: the system of phrenology devised by (...) Franz Joseph Gall, and William Lawrence’s lectures at the Royal College of Surgeons. Both owed a profound intellectual debt to continental comparative anatomy. In the final quarter of the 18th-century, Johann Friedrich Blumenbach, Petrus Camper and Johann Gottfried von Herder had broken away from the traditional doctrine of the Great Chain of Being by allowing for a clear anatomical distinction between ‘man’ and beast based on the morphology of the skull. This reconceptualization of man as an anatomically distinct being gave Gall and Lawrence grounds to propose that the peculiarities of the human mind were dependent on mankind’s unique cerebral size and structure.

Empiricism is a claim about the contents of the mind: its classic slogan is nihil est in intellectu quod non fuerit in sensu, ‘there is nothing in the mind (intellect, understanding) which is not first in the senses’. As such, it is not a claim about the fundamental nature of the world as material. I focus here on in an instance of what one might term the materialist appropriation of empiricism. One major component in the transition from a purely epistemological (...) claim about the mind and its contents, to an ontological claim about the nature of the world, is the new focus on brain-mind relations in the eighteenth century. Here I examine a Lockean trajectory as exemplified in Joseph Priestley’s 1777 Disquisitions Relating to Matter and Spirit. But Locke explicitly ruled out that his inquiry into the logic of ideas amounted to a ‘physical consideration of the mind’. What does it mean, then, for Priestley to present himself as continuing a Lockean tradition, while presenting mental processes as tightly identified with ‘an organical structure such as that of the brain’ (although he was not making a strict identity claim as we might understand it, post-Smart and Armstrong)? One issue here is that of Priestley's source of ‘empirical data’ regarding the correlation and indeed identification of mental and cerebral processes. David Hartley’s theory in his 1749 Observations on Man was, as is well known, republished in abridged form by Priestley, but he discards Hartley's 'vibratory neurophysiology' while retaining the associationist framework, although not because he disagreed with the former. Yet Hartley was at the very least, strongly agnostic about metaphysical issues (and it is difficult to study these authors while bracketing off religious considerations). One could see Locke and Hartley as articulating programs for the study of the mind which were more or less naturalistic (more strongly so in Hartley’s case) while avoiding ‘materialism’ per se; in contrast, Priestley bit the (materialist) bullet. In this paper I examine Priestley’s appropriation and reconstruction of this ‘micro-tradition’, while emphasizing its problems. (shrink)

This paper describes the affinities between Socinian and Unitarian materialism. Based on different philosophical traditions, the Socinian Christoph Stegmann and the Unitarian Joseph Priestley developed a strong “system of materialism” which fit very well with Christian doctrines and the Bible. The conviction that the whole man is material and therefore mortal became the common basis for these radical thinkers. Stegmann formulated within the Aristotelian tradition a “non-reductive” materialism in which matter, not form, became the fundamental principle of all living things. (...) Priestley, on the other hand, created his “absolute” materialism by developing a new understanding of the concept of matter according to the philosophical rules of Isaac Newton. The paper will discuss the affinities and differences between these two different concepts of materialism. The idea of a thinking matter, most prominently formulated by John Locke, will serve as a link between them. (shrink)

The purpose of this paper is to elucidate two interesting parallels between views discussed in John Wilkins’ Of the Principles and Duties of Natural Religion and positions developed by John Locke in his Essay Concerning Human Understanding. The first parallel pertains to a faculty of inner sense. Both authors carve out a central role for this introspective perceptual modality. The second parallel pertains to volition and free will. Both authors employ an investigative methodology which privileges first-personal experiences of choosing and (...) willing. I also discuss the relationship between these two parallels and speculate about their significance. (shrink)
