Towards the end of his life, Descartes published the first four parts of a projected six-part work, The Principles of Philosophy. This was intended to be the definitive statement of his complete system of philosophy, dealing with everything from cosmology to the nature of human happiness. In this book, Stephen Gaukroger examines the whole system, and reconstructs the last two parts, 'On Living Things' and 'On Man', from Descartes' other writings. He relates the work to the tradition (...) of late Scholastic textbooks which it follows, and also to Descartes' other philosophical writings, and he examines the ways in which Descartes transformed not only the practice of natural philosophy but also our understanding of what it is to be a philosopher. His book is a comprehensive examination of Descartes' complete philosophical system. (shrink)

ABSTRACT It has long been recognised that Adam Smith’s Wealth of Nations (1776) advances a ‘system of natural liberty’ in seeking to account for the ‘nature and causes of the wealth of nations.’ This is not however a theme that is explored or explained in the early sections of the book; in fact, not until Book IV, Ch. ix does Smith give his most expansive account of what he might mean by this term. This paper examines this chapter (...) in detail to determine the limits of his critique in that chapter of the ‘agricultural system’ (of Physiocracy), and why it might be that Smith is so parsimonious in offering a clear account of his central idea.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 41.4 (2003) 558-559 [Access article in PDF] Stephen Gaukroger. Descartes' System of Natural Philosophy. New York: Cambridge University Press, 2002. Pp. viii + 258. Cloth, $60.00. Paper, $22.00. Stephen Gaukroger, author of a definitive biography of Descartes, has now written an excellent account of Descartes's natural philosophy as presented in his Principia philosophiae. Gaukroger claims that the roots of modernity lay in (...) the philosophies of Francis Bacon and René Descartes, both of whom regarded natural philosophy, rather than either moral philosophy or metaphysics, as the core of the philosophical enterprise. Whereas Bacon developed his ideas from a background steeped in the writings of the Renaissance humanists who emphasized moral philosophy, Descartes developed his ideas in the context of Scholastic philosophy, particularly the textbooks of the Jesuits that he had encountered at La Flèche and that located the foundations of philosophy in metaphysics.Regarding the unpublished early works, Le monde and L'homme, as suppressed parts of Descartes's mature project and taking seriously Descartes's stated intention of dealing with living things and humans along with the physical world in his natural philosophy, Gaukroger presents a detailed account of this "complete" version of the Principia philosophiae. In a series of six chapters, he explicates Descartes's views on the principles of knowledge, the principles of material objects, the visible universe, the Earth, living things, and man. In addition to Le monde and L'homme, Gaukroger draws on Les Passions de l'âme as an important source for Descartes's views on human nature.Gaukroger situates Descartes's natural philosophy in the context of the Scholastic textbook tradition in a chapter preceding his account of the Principa philosophiae. He delves into the history of medieval universities, the place of natural philosophy in the medieval curriculum, and the changing relationship between metaphysics and natural philosophy, particularly after the Condemnations of 1277. Difficulties in reconciling Aristotelian natural philosophy and Christian theology, which had been formulated in terms of Aristotelian metaphysics, continued into the sixteenth century and provided the immediate background to the Jesuit commentaries and textbooks to which Descartes was exposed as a student. In these works, Jesuit philosophers attempted to derive a coherently unified Christian Aristotelianism from first principles. Gaukroger reminds us that Descartes's Principia philosophiae was a deliberate attempt to replace these Jesuit textbooks with one based on mechanistic principles.Despite the strength of Gaukroger's book as a contextualized study of a major philosophical figure who is frequently treated in an entirely ahistorical way, the book is not without its problems. The main problem is one that plagues many studies of Descartes (and other canonical figures in the history of philosophy), to wit, the presumption that he is somehow unique. For example, Gaukroger writes at length about Descartes's views about the differences between animals and humans with regard to cognition, arguing that Descartes did not consider animals to be automata because they lack rational souls but rather that they actually experience some but not all of the more abstract or reflexive forms of cognition usually ascribed to humans. Gaukroger does not mention the fact that many other early modern philosophers held a view like this. For example, Descartes's contemporary and fellow mechanical philosopher Pierre Gassendi claimed that animals could know universals, as when a dog recognizes that it is a human that is approaching, but differ from humans in not being capable of contemplating the nature of universality per se. Descartes was part of a community of thinkers concerned with similar problems, and his natural philosophy can be illuminated by viewing him in that context as well as against the backdrop of Scholasticism.Gaukroger underplays the significance of theology for Descartes's philosophy. Although he discusses how God's attributes, especially immutability, provide the basis for Descartes's laws of motion, he does not explore the specific aspects of Descartes's theological presuppositions and the way they influenced his entire natural philosophical project. Gaukroger repeats the received view that "One of the principal tasks of a mechanistic natural philosophy... (shrink)

This paper presents two systems of natural deduction for the rejection of non-tautologies of classical propositional logic. The first system is sound and complete with respect to the body of all non-tautologies, the second system is sound and complete with respect to the body of all contradictions. The second system is a subsystem of the first. Starting with Jan Łukasiewicz's work, we describe the historical development of theories of rejection for classical propositional logic. Subsequently, we present the (...) two systems of natural deduction and prove them to be sound and complete. We conclude with a ‘Theorem of Inversion’. (shrink)

The main result of this paper is a normalizing system of natural deduction for the full language of intuitionistic linear logic. No explicit weakening or contraction rules for -formulas are needed. By the systematic use of general elimination rules a correspondence between normal derivations and cut-free derivations in sequent calculus is obtained. Normalization and the subformula property for normal derivations follow through translation to sequent calculus and cut-elimination.

David Lewis's best-system analysis of laws of nature is perhaps the best known sophisticated regularity theory of laws. Its strengths are widely recognized, even by some of its ablest critics. Yet it suffers from what appears to be a glaring weakness: It seems to grant an arbitrary privilege to the standards of our own scientific culture. I argue that by reformulating, or reinterpreting, Lewis's exposition of the best-system analysis, we arrive at a view that is free of (...) this weakness. The resulting theory of laws has the surprising consequence that the term "law of nature" is indexical. (shrink)

One of Gottfried Wilhelm Leibniz’s most distinctive philosophical theories is the pre-established harmony, his big-picture explanation for the appearance of causal interaction in the world. According to Leibniz, and despite how it seems, neither you, me, nor any other thing created by God can cause changes in any other thing! When I high-five you, it’s not really me that causes the stinging sensation in your hand. Instead, every change each created thing undergoes—including that sting in your hand—is actually, surprising as (...) it might seem, caused internally by that thing itself. But then, why does the world appear to be a place of orderly, law-like pushings and pullings, actions and reactions? This is because God chose to create only those things that would each, of its own internal nature, cause changes in itself in perfect harmony with what every other created thing causes in itself, sort of like a symphony of automata programmed and synchronized to play their own individual parts of the same overall composition in perfect, well, harmony. Leibniz offers perhaps his best-known statement of the pre-established harmony in “A New System of Nature” (1695), where he also argues that we ought to accept his theory instead of its major competitors at the time, namely, Descartes’s interactionism and Malebranche’s occasionalism. The present work is an open-access, peer-reviewed, and user-friendly version of "A New System of Nature”, intended for use in teaching courses on early modern philosophy. It's edited for clarity and accessibility, and includes commentary, examples, and other elements meant to help engage readers. (shrink)

PARC is an "appended numeral" system of natural deduction that I learned as an undergraduate and have taught for many years. Despite its considerable pedagogical strengths, PARC appears to have never been published. The system features explicit "tracking" of premises and assumptions throughout a derivation, the collapsing of indirect proofs into conditional proofs, and a very simple set of quantificational rules without the long list of exceptions that bedevil students learning existential instantiation and universal generalization. The system (...) can be used with any Copi-style set of inference rules, so it is quite adaptable to many mainstream symbolic logic textbooks. Consequently, PARC may be especially attractive to logic teachers who find Jaskowski/Gentzen-style introduction/elimination rules to be far less "natural" than Copi-style rules. The PARC system is also keyboard-friendly in comparison to the widely adopted Jaskowski-style graphical subproof system of natural deduction, viz., Fitch diagrams and Copi "bent arrow" diagrams.

The way from linearly written derivations in natural deduction, introduced by Jaskowski and often used in textbooks, is a straightforward root-first translation. The other direction, instead, is tricky, because of the partially ordered assumption formulas in a tree that can get closed by the end of a derivation. An algorithm is defined that operates alternatively from the leaves and root of a derivation and solves the problem.

Among the far-reaching impacts of COVID-19 is its impact on care systems, the social and other systems that we rely in to maintain and provide care for those with “illness.” This paper will examine these impacts through a description of the influence on palliative care systems that have arisen within this pandemic. It will explore the impact on the meaning of care, how care is performed and identified, and the responses of palliative care systems to these challenges. It will also (...) highlight the current and potential future implications of these dynamics within the unfolding crisis of this pandemic. (shrink)

A materialist construction of semiosis requires system embodiment at particular locales, in order to function as systems of interpretance. I propose that we can use a systemic model of scientific measurement to construct a systems view of semiosis. I further suggest that the categories required to understand that process can be used as templates when generalizing to biosemiosis and beyond. The viewpoint I advance here is that of natural philosophy—which, once granted, incurs no principled block to further generalization all (...) the way to pansemiotics—nearer to Peirce’s own very general perspective. This project requires a hylozooic framework, which I present in the form of a specification hierarchy, whereby physical dynamics subsume all other transactions at more highly developed integrative levels. The upshot of the paper is a proposal that meanings can be assimilated most generally to final causes. (shrink)

Contextualizing the emergence of history of philosophy within eighteenth-century German Enlightenment, this book discusses the philosophical nature of the historiographical concept ‘system of philosophy’ and the concept’s influence upon the methods of history of philosophy and history of ideas.

Considerations arising in the context of burgeoning concerns about the environment can provoke an exploration of issues that have significance both for environmental education in particular and education more generally. Notions of the ‘greater whole’ and ‘systemic wisdom’ that feature in some strands of environmental discourse are a case in point. It is argued that interpretations of these notions arising in currently influential scientific and systems thinking understandings of nature that attempt to overcome a corrosive separation of humankind and (...) nature through a dilution or dismissal of the distinction between the human and non-human, self and other, require critical evaluation if they are not to bring their own dangers. Merleau-Pontian understandings of object constitution in a subjectively informed life-world and ideas of the ‘selving’ of natural things are drawn upon in developing a non-discursively grounded interpretation of systemic wisdom. The latter is taken to raise questions that have considerable transformative potential for conventional views of knowledge and its curriculum organisation. (shrink)

Many philosophers who do not analyze laws of nature as the axioms and theorems of the best deductive systems nevertheless believe that membership in those systems is evidence for being a law. This raises the question, “If the best systems analysis fails, what explains the fact that being a member of the best systems is evidence for being a law?” In this essay I answer this question on behalf of Leibniz. I argue that although Leibniz’s philosophy of laws is (...) inconsistent with the best systems analysis, his philosophy of nature’s perfection enables him to explain why membership in the best systems is evidence for being a law of nature.

Acidic substances were known for thousands of years, and their macroscopic-sensory characteristics were reflected by words in most ancient languages. In the Western canon, the history of the concept of acidity goes back to Ancient Greece. In Greek, the word associated with acidity from its early literary references was ὀξύς (“sharp”), and still in contemporary Greek the words “sour” and “acidic” have the same root. This paper makes a short presentation of the appearance of the abstract concept in the works (...) of Plato and Aristotle and relates it, on one side to the already existing theological-philosophical tradition, starting with Hesiod´s Theogony and on the other, to the then available to the Greeks organoleptic experiences of sourness-vinegar and sour milk.

For its elliptical style, What is Philosophy? appears to be fragmentary and inscrutable, and its reception has been correspondingly contentious. Following an intimation by Gilles Deleuze himself, this article proposes that his final book, written in collaboration with Félix Guattari, contains a philosophy of nature. To address this proposition, the article begins by outlining the comprehensive system of nature set out in What is Philosophy?, defining it as an open system in motion that conjoins philosophy with (...) the historical preconditions and intersects it with science and art. The article then addresses the precise method whereby the philosopher as an individual subject, emerging from nature, can succeed in becoming creative – that is, in creating concepts to bring forth new events. Finally, the brain turns out to be the pivot between the system and this method. What is Philosophy? thus presents an account of the brain based on a theory of the three specific planes of philosophy, science and art, and uses it to expand upon the idea of assemblage for a philosophy of nature.

What seem to be Kurt Gödel’s first notes on logic, an exercise notebook of 84 pages, contains formal proofs in higher-order arithmetic and set theory. The choice of these topics is clearly suggested by their inclusion in Hilbert and Ackermann’s logic book of 1928, the Grundzüge der theoretischen Logik. Such proofs are notoriously hard to construct within axiomatic logic. Gödel takes without further ado into use a linear system of natural deduction for the full language of higher-order logic, with (...) formal derivations closer to one hundred steps in length and up to four nested temporary assumptions with their scope indicated by vertical intermittent lines.

Wes Furlotte critically evaluates Hegel's philosophy of human freedom in terms of his often-disregarded conception of nature. In doing so, he gives us a new portrait of Hegel's final system that is surprisingly relevant for our contemporary world, connecting it with recent work in speculative realism and new materialism.

Burlamaqui, J[ean] J[acques]. The Principles of Natural Law.

Rights of nature is an idea that has come of age. In recent years, a diverse range of countries and jurisdictions have adopted these norms, which involve granting legal rights to nature or natural objects, such as rivers, forests, or ecosystems. This book critically examines the idea of natural objects as right-holders, and analyses legal cases, policies, and philosophical issues relating to this development. -/- Drawing on contributions from a range of experts in the field, Rights of (...) class='Hi'>Nature: A Re-examination investigates the potential for this innovative idea to revolutionize the concepts of rights, standing, and recognition as traditionally understood in many legal systems. Taking as its starting point Stone’s influential 1972 article ‘Should Trees Have Standing?’, the book examines the progress rights of nature have made since that time, by identifying central themes, unifying principles, and key distinctions in how rights of nature discourse has been operationalized in the disciplines of law, philosophy, and the social sciences. These themes and principles are illustrated through a wide variety of examples, including ecosystem services, indigenous thinking, and ecological restoration, demonstrating how the relationship between humanity and the natural world may be transforming. -/- Taking a philosophical, political, and legal perspective, this book will be of great interest to students and scholars of environmental law and policy, environmental ethics, and philosophy.

The merits of David Lewis’s Best System Account of natural law are frequently debated. But to my knowledge, the prospects for extending the BSA to cover meta-laws have never been examined. I shall identify two obstacles facing the most natural way of extending the BSA to cover meta-laws. The BSA’s fans should consider how these obstacles are to be overcome. Meta-laws are laws about laws. For example, Einstein’s special theory of relativity incorporates a meta-law: The content of the [special] (...) relativity theory can … be summarized in one sentence: all natural laws must be so conditioned that they are covariant with respect to Lorentz transformations. [The special theory of relativity] is not a theory in the usual sense but is better regarded as a second-level theory, or a theory of theories that constrains first-level theories. The principle of relativity is an example of a symmetry principle: a principle requiring that the first-order laws be unchanged under a given transformation. Long before Einstein proposed the principle of relativity, other spacetime symmetries were widely believed to be meta-laws: that the first-order laws are covariant under arbitrary spatial displacements, temporal displacements and spatial rotations. These spacetime symmetries require the laws to treat all spatial locations and directions alike and all moments alike. For instance, symmetry under temporal displacements rules out a fundamental force law specifying that a given force declines with the inverse-square of the distance before a given moment but with the inverse-cube of the distance at and after that moment. Wigner characterizes such a symmetry principle as ‘a superprinciple which is in …. (shrink)
