Leibniz’s religious cosmopolitanism is one of the main ways in which his thought foreshadows the Enlightenment. Of the controversial issues of his time, it is the one on which he was boldest. His commitment to it is discussed here in relation to both the Chinese Rites Controversy and the reunion of Christendom, and the main features of his conception of religion are discussed. (1) It is a religious and normative conception. (2) Its main principle is “the love of God above (...) all things.” (3) It involves a principled pragmatism on many, perhaps most, religious issues. The implications of this pragmatism are traced for (4) Leibniz’s ecclesiology and (5) his strategies for interpreting religious concepts. (6) The relatively abstract and ahistorical character of religious essentials on Leibniz’s view is acknowledged. (shrink)

Legendary since his own time as a universal genius, Gottfried Wilhelm Leibniz (1646-1716) contributed significantly to almost every branch of learning. One of the creators of modern mathematics, and probably the most sophisticated logician between the Middle Ages and Frege, as well as a pioneer of ecumenical theology, he also wrote extensively on such diverse subjects as history, geology, and physics. But the part of his work that is most studied today is probably his writings in metaphysics, which have been (...) the focus of particularly lively philosophical discussion in the last twenty years or so. The writings contain one of the great classic systems of modern philosophy, but the system must be pieced together from a vast and miscellaneous array of manuscripts, letters, articles, and books, in a way that makes especially strenuous demands on scholarship. This book presents an in-depth interpretation of three important parts of Leibniz's metaphysics, thoroughly grounded in the texts as well as in philosophical analysis and critique. The three areas discussed are the metaphysical part of Leibniz's philosophy of logic, his essentially theological treatment of the central issues of ontology, and his theory of substance (the famous theory of monads).

A standard strategy for defending a claim of non-identity is one which invokes Leibniz’s Law. (1) Fa (2) ~Fb (3) (∀x)(∀y)(x=y ⊃ (∀P)(Px ⊃ Py)) (4) a=b ⊃ (Fa ⊃ Fb) (5) a≠b In Kalderon’s view, this basic strategy underlies both Moore’s Open Question Argument (OQA) as well as (a variant formulation of) Frege’s puzzle (FP). In the former case, the argument runs from the fact that some natural property—call it “F-ness”—has, but goodness lacks, the (2nd order) property of its (...) being an open question whether everything that instantiates it is good to the conclusion that goodness and F-ness are distinct. And in the latter case, the argument runs from the fact that that Hesperus has, but Phosphorus lacks, the property of being believed by the ancient astronomers to be visible in the evening sky to the conclusion that Hesperus and Phosphorus are distinct. Kalderon argues that both the OQA and FP fail because in neither case is there good reason to believe that both (1) and (2) are true. The reason we are tempted to believe that they are true is because we mistake de dicto claims for de re claims. In order for FP to go through, the truth of the following de re claims needs to be established: FP1) Hesperus was believed by the ancient astronomers to be visible in the evening sky. (shrink)

Of all the thinkers of the century of genius that inaugurated modern philosophy, none lived an intellectual life more rich and varied than Gottfried Wilhelm Leibniz (1646-1716). Trained as a jurist and employed as a counsellor, librarian, and historian, he made famous contributions to logic, mathematics, physics, and metaphysics, yet viewed his own aspirations as ultimately ethical and theological, and married these theoretical concerns with politics, diplomacy, and an equally broad range of practical reforms: juridical, economic, administrative, technological, medical, and (...) ecclesiastical. Maria Rosa Antognazza's pioneering biography not only surveys the full breadth and depth of these theoretical interests and practical activities, it also weaves them together for the first time into a unified portrait of this unique thinker and the world from which he came. At the centre of the huge range of Leibniz's apparently miscellaneous endeavours, Antognazza reveals a single master project lending unity to his extraordinarily multifaceted life's work. Throughout the vicissitudes of his long life, Leibniz tenaciously pursued the dream of a systematic reform and advancement of all the sciences, to be undertaken as a collaborative enterprise supported by an enlightened ruler; these theoretical pursuits were in turn ultimately grounded in a practical goal: the improvement of the human condition and thereby the celebration of the glory of God in His creation. As well as tracing the threads of continuity that bound these theoretical and practical activities to this all-embracing plan, this illuminating study also traces these threads back into the intellectual traditions of the Holy Roman Empire in which Leibniz lived and throughout the broader intellectual networks that linked him to patrons in countries as distant as Russia and to correspondents as far afield as China.

As one might expect, throughout his life Leibniz assumed an attitude of religious toleration both ad intra (that is, toward Christians of other confessions) and ad extra (that is, toward non-Christians, notably Muslims). The aim of this paper is to uncover the philosophical and theological foundations of Leibniz’s views on this subject. Focusing in particular on his epistolary exchange with the French Catholic convert Paul Pellisson-Fontanier, I argue that neither toleration ad intra nor toleration ad extra is grounded for Leibniz (...) in indifference toward the content of revealed religion. On the contrary, Leibniz remained convinced of the objective truth of the Christian religion as it is handed down by the millennia-old tradition of the truly universal church. In his view, reasons internal to the very nature of salvation and to the conception of God and man explicitly contained in or, at least, in accord with this tradition present religious toleration as the only justifiable answer to the differences among religions.

This paper discusses Leibniz's Trinitarian doctrine in the light of his philosophy, as revealed by a set of virtually unstudied texts. The first part of the paper examines Leibniz's defence of the Trinity against the charge of contradiction as a necessary precondition to the development of his own conception of the Trinity. The second part discusses some of the key features of Leibniz's Trinitarian doctrine, notably his conception of person, the analogy between the human mind and the Trinity, and the (...) problem of Trinitarian relations.

In this paper I will discuss certain aspects of Leibniz's theory and practice of 'soft reasoning' as exemplified by his defence of two central mysteries of the Christian revelation: the Trinity and the Incarnation. By theory and practice of 'soft' or 'broad' reasoning, I mean the development of rational strategies which can successefully be applied to the many areas of human understanding which escape strict demonstration, that is, the 'hard' or 'narrow' reasoning typical of mathematical argumentation. These strategies disclose an (...) 'other' reason, i.e. a complementary set of arguments and methods developed by Leibniz in order to deal with crucial issues such as the 'weighting' of probabilities and truths of fact. I will argue that one of the most compelling examples of the importance and fertility of Leibniz's 'other' reason is provided by his solution to the problems posed by the unique epistemological status of theological mysteries.

Reminiscing about his early views on the continuum problem in a dialogue penned in 1689,2 Leibniz recalled the period in his youth when he had enthusiastically subscribed to the "New Philosophy", embracing the composition of the continuum out of points and the doctrine that “a slower motion is one interrupted by small intervals of rest.”3 Speaking of himself through the character Lubinianus, he continues: And I indulged other dogmas of this kind, to which people are prone when they are willing (...) to entertain every imagination, and do not notice the infinity lurking everywhere in things. But although when I became a geometer I relinquished these opinions, atoms and the vacuum held out for a long time, like certain relics in my mind rebelling against the idea of infinity; for even though I conceded that every continuum could be divided to infinity in thought, I still did not grasp that in reality there were parts in things exceeding every number, as a consequence of motion in a plenum. That “atoms and the vacuum held out for a long time” among Leibniz’s cherished views is readily confirmed by an examination of his manuscripts. One may find papers containing some measure of commitment to atomism intermittently throughout the period from 1666 to 1676; moreover, if his later memory is to be trusted, he first “gave himself over to” atomism as early as 1661.4 As for his reasons for rejecting atoms, Leibniz’s mature..

I am so in favor of the actual infinite that instead of admitting that Nature abhors it, as is commonly said, I hold that Nature makes frequent use of it everywhere, in order to show more effectively the perfections of its Author. Thus I believe that there is no part of matter which is not, I do not say divisible, but actually divided; and consequently the least particle ought to be considered as a world full of an infinity of different (...) creatures.

In a recent note in this review (Leibniz e gli Zenonisti, n. 3, 2001, pp. 15-22) Paolo Rossi stresses the importance of a philosophical sect that he claims has been unjustly ignored in accounts of the history of modern philosophy, the Jesuit philosophers of Louvain and Spain of the late sixteenth and early seventeenth century known as the Zenonists. The occasion for his complaint is Massimo Mugnai’s admirable new introduction to Leibniz’s thought (Introduzione alla filosofia di Leibniz, Torino, Einaudi, 2001), (...) which in all other respects than its failure to mention the Zenonists, Rossi compliments and commends: justly, for in my opinion it is the best introduction to Leibniz yet written.

Newton and Leibniz had profound disagreements concerning metaphysics and the relationship of mathematics to natural philosophy, as well as deeply opposed attitudes towards analysis. Nevertheless, or so I shall argue, despite these deeply held and distracting differences in their background assumptions and metaphysical views, there was a considerable consilience in their positions on the status of infinitesimals. In this paper I compare the foundation Newton provides in his Method Of First and Ultimate Ratios (sketched at some time between 1671 and (...) 1684, and published in the Principia of 1687) with that provided independently by Leibniz in his unpublished manuscript De quadratura arithmetica (1675-6) as well as in later writings. I argue that both appeal to a version of the Archimedean Axiom to underwrite their use of infinitesimal techniques, which must be interpreted as a shorthand for rigorously finitist methods. (shrink)

In this paper we argue for the robustness of Leibniz's commitment to the reality (but not substantiality) of body. We claim that a number of his most important metaphysical doctrines — among them, psychophysical parallelism, the harmony between efficient and final causes, the connection of all things, and the argument for the plurality of substances stemming from his solution to the continuum problem— make no sense if he is interpreted as giving an eliminative reduction of bodies to perceptions.

As is well known, one of Leibniz’s seminal insights in his work on series concerned sums of differences. If from a given series A one forms a difference series B whose terms are the differences of the successive terms of A, the sum of the terms in the B series is simply the difference between the last and first terms of the original series: “the sum of the differences is the difference between the first term and the last” (A vii.3, (...) p. 95). This insight, so far as I now, has never been named; I shall call it the Difference Principle. Suitably generalized, it becomes the basis for the fundamental theorem of the calculus: the sum (integral) of the differentials equals the difference of the sums (the definite integral evaluated between last and first terms), ∫ Bdx = [A]fi. As is well known, the Difference Principle has its origin in the problem set him by Huygens in September 1672 to find the sum of the reciprocal triangular numbers. This date is, incidentally, confirmed by Leibniz himself in Summa fractionum a figuratis, per aequationes (A vii.3, p. 365 ), as well as by the first piece in A vii.3, De summa numerorum triangulorum recipricorum (p. 3), although in his Origo inventionis trianguli harmonici of the Winter of 1675-76 he misremembers it as “Anno 1673” (p. 712). Leibniz explains the algorithm in a letter to Meissner 21 years later: “If one wants to add, for example, the first five.. (shrink)

In this paper I attempt to trace the development of Gottfried Leibniz’s early thought on the status of the actually infinitely small in relation to the continuum. I argue that before he arrived at his mature interpretation of infinitesimals as fictions, he had advocated their existence as actually existing entities in the continuum. From among his early attempts on the continuum problem I distinguish four distinct phases in his interpretation of infinitesimals: (i) (1669) the continuum consists of assignable points separated (...) by unassignable gaps; (ii) (1670-71) the continuum is composed of an infinity of indivisible points, or parts smaller than any assignable, with no gaps between them; (iii) (1672-75) a continuous line is composed not of points but of infinitely many infinitesimal lines, each of which is divisible and proportional to a generating motion at an instant (conatus); (iv) (1676 onward) infinitesimals are fictitious entities, which may be used as compendia loquendi to abbreviate mathematical reasonings; they are justifiable in terms of finite quantities taken as arbitrarily small, in such a way that the resulting error is smaller than any pre-assigned margin. Thus according to this analysis Leibniz arrived at his interpretation of infinitesimals as fictions already in 1676, and not in the 1700's in response to the controversy between Nieuwentijt and Varignon, as is often believed. (shrink)

In contrast with some recent theories of infinitesimals as non-Archimedean entities, Leibniz’s mature interpretation was fully in accord with the Archimedean Axiom: infinitesimals are fictions, whose treatment as entities incomparably smaller than finite quantities is justifiable wholly in terms of variable finite quantities that can be taken as small as desired, i.e. syncategorematically. In this paper I explain this syncategorematic interpretation, and how Leibniz used it to justify the calculus. I then compare it with the approach of Smooth Infinitesimal Analysis (...) (SIA), as propounded by John Bell. Despite many parallels between SIA and Leibniz’s approach —the non-punctiform nature of infinitesimals, their acting as parts of the continuum, the dependence on variables (as opposed to the static quantities of both Standard and Non-standard Analysis), the resolution of curves into infinitesided polygons, and the finessing of a commitment to the existence of infinitesimals— I find some salient differences, especially with regard to higher-order infinitesimals. These differences are illustrated by a consideration of how each approach might be applied to Newton’s Proposition 6 of the Principia, and the derivation from it of the v2/r law for the centripetal force on a body orbiting around a centre of force. It is found that while Leibniz’s syncategorematic approach is adequate to ground a Leibnizian version of the v2/r law for the “solicitation” ddr experienced by the orbiting body, there is no corresponding possibility for a derivation of the law by nilsquare infinitesimals; and while SIA can allow for second order differentials if nilcube infinitesimals are assumed, difficulties remain concerning the compatibility of nilcube infinitesimals with the principles of SIA, and in any case render the type of infinitesimal analysis adopted dependent on its applicability to the problem at hand.

Gottfried Leibniz is well known for his claim to have “rehabilitated” the substantial forms of scholastic philosophy, forging a reconciliation of the New Philosophy of Descartes, Mersenne and Gassendi with Aristotelian metaphysics (in his so-called Discourse on Metaphysics, 1686). Much less celebrated is the fact that fifty years earlier (in his Hypomnemata Physica, 1636) the Bratislavan physician and natural philosopher Daniel Sennert had already argued for the indispensability to atomism of (suitably re-interpreted) Aristotelian forms, in explicit opposition to the rejection (...) of substantial forms by his fellow atomist Sébastien Basson.1..

In this paper I challenge the usual interpretations of Newton's and Leibniz's views on the nature of space and the relativity of motion. Newton's ‘relative space’ is not a reference frame; and Leibniz did not regard space as defined with respect to actual enduring bodies. Newton did not subscribe to the relativity of intertial motions; whereas Leibniz believed no body to be at rest, and Newton's absolute motion to be a useful fiction. A more accurate rendering of the opposition between (...) them, I argue, leads to a wholly different understanding of Leibniz's theory of space, one which is not susceptible to the objections Newton had raised against Descartes regarding the representation of motion. This in turn suggests a new approach for contemporary theory of space, one which neither hypostatizes space nor tries to reduce it to relations among actual things. * This work was generously supported by the National Endowment for the Humanities, with a Fellowship for College Teachers and Independent Scholars (FB-26897-89), and also by a sabbatical leave from my institution, Middlebury College.

Before establishing his mature interpretation of infinitesimals as fictions, Gottfried Leibniz had advocated their existence as actually existing entities in the continuum. In this paper I trace the development of these early attempts, distinguishing three distinct phases in his interpretation of infinitesimals prior to his adopting a fictionalist interpretation: (i) (1669) the continuum consists of assignable points separated by unassignable gaps; (ii) (1670-71) the continuum is composed of an infinity of indivisible points, or parts smaller than any assignable, with no (...) gaps between them; (iii) (1672- 75) a continuous line is composed not of points but of infinitely many infinitesimal lines, each of which is divisible and proportional to a generating motion at an instant (conatus). In 1676, finally, Leibniz ceased to regard infinitesimals as actual, opting instead for an interpretation of them as fictitious entities which may be used as compendia loquendi to abbreviate mathematical reasonings.

In this paper I offer a fresh interpretation of Leibniz’s theory of space, in which I explain the connection of his relational theory to both his mathematical theory of analysis situs and his theory of substance. I argue that the elements of his mature theory are not bare bodies (as on a standard relationalist view) nor bare points (as on an absolutist view), but situations . Regarded as an accident of an individual body, a situation is the complex of its (...) angles and distances to other co-existing bodies, founded in the representation or state of the substance or substances contained in the body. The complex of all such mutually compatible situations of co-existing bodies constitutes an order of situations , or instantaneous space. Because these relations of situation change from one instant to another, space is an accidental whole that is continuously changing and becoming something different, and therefore a phenomenon. As Leibniz explains to Clarke, it can be represented mathematically by supposing some set of existents hypothetically (and counterfactually) to remain in a fixed mutual relation of situation, and gauging all subsequent situations in terms of transformations with respect to this initial set. Space conceived in terms of such allowable transformations is the subject of Analysis Situs. Finally, insofar as space is conceived in abstraction from any bodies that might individuate the situations, it encompasses all possible relations of situation. This abstract space , the order of all possible situations , is an abstract entity, and therefore ideal. (shrink)

In this paper I attempt to throw new light on Leibniz's apparently conflicting remarks concerning the continuity of matter. He says that matter is "discrete" yet "actually divided to infinity" and (thus dense), and moreover that it fills (continuous) space. I defend Leibniz from the charge of inconsistency by examining the historical development of his views on continuity in their physical and mathematical context, and also by pointing up the striking similarities of his construal of continuity to the approach taken (...) by 20th century Combinatorial Topology.

Leibniz saw the question of the eucharist as a crucial stumbling block to the agreement between Lutherans and Calvinists. Mandated together with Daniel Ernst Jablonsky to prepare working documents for the negotiations between Hanover and Brandenburg in 1697, Leibniz carefully read through the Calvinist Confessions of faith and the works of Calvin in their 1671 edition. He made an extensive collection of excerpts from the Confessions of faith and from Calvin's Institutes all intended to show that Calvinists admitted the substantial (...) presence of Christ's body in the eucharist. (This collection of excerpts is analysed here for the first time and compared with another little-known document, the Unvorgreiffliches Bedencken). L. had argued previously in 1691/92 that, contrary to the assertions of Pellisson-Fontanier, his own conception of substance and of Christ's presence in the eucharist was completely different from Calvin's. However, by 1697, it was clear to Leibniz that Calvin's concept of substance, which was broadly speaking Aristotelian, was never defined clearly by the reformer, and could be made to coincide with Leibniz's own notion of substance as force rather than substance in its dimensional sense. At the same time L. dissociated Ubiquitarianism (doctrine characteristic of late sixteenth century Lutheranism, which defended the dimensional presence of Christ's body in heaven and in the eucharist, by arguing that Christ in his divine nature could cause his physical body to be present in several places at the same time) from Lutheranism. He also drove a wedge between the doctrines of Zwingli and Calvin. L. thus attempted to find religious union on a common ontology and he might well have succeeded if it were not for complex political circumstances, which ultimately caused the failure of the negotiations.

Leibniz has enjoyed a prominent place in the history of thought about possible worlds.' I shall argue that on the feading interpretation of Leibniz's account of contingency — an ingenious interpretation with ample textual support — possible worlds may be invoked by Leibniz only on pain of inconsistency. Leibnizian contingency, as reconstructed in detail by Robert C. Sleigh, Jr.,z will be shown to preclude propositions with different truth-values in different possible worlds.

Extension is probably the most general natural property. Is it a fundamental property? Leibniz claimed the answer was no, and that the structureless intuition of extension concealed more fundamental properties and relations. This paper follows Leibniz's program through Herbart and Riemann to Grassmann and uses Grassmann's algebra of points to build up levels of extensions algebraically. Finally, the connection between extension and measurement is considered.

In this paper, I examine Leibniz’s account of the epistemic status of the Christian Mysteries in his “Preliminary Dissertation on the Conformity of Faith with Reason.” In it, the Mysteries are held to be true, yet also to be beyond human comprehension. This conjunction gives rise to a dilemma: how can the Mysteries bemeaningfully asserted if they are unintelligible? To answer this, Leibniz compares them to natural truths, which are demonstrable by God alone. To complicate matters, however, he suggests that (...) certain Mysteries have the status of truths of logic, or of mathematics; this raises a special problem in understanding his view of the epistemic status of such Mysteries for us. I offer a suggestion as to how he may have wanted us to think of the relationship between these Mysteries and our faculty of comprehension. I then employ my conclusions in explaining Leibniz’s answer to Bayle’s skepticism regarding the Mysteries, as well as in explaining his answer to the question as to how belief in the Mysteries can be rationally justified.

This book introduces the reader to Whitehead’s complex and often misunderstood metaphysics by showing that it deals with questions about the nature of causation originally raised by the philosophy of Leibniz. Whitehead’s philosophy is an attempt at rehabilitating Leibniz’s theory of monads by recasting it in terms of novel ontological categories.

New light is shed on Leibniz’s commitment to the metaphysical priority of the intensional interpretation of logic by considering the arithmetical and graphical representations of syllogistic inference that Leibniz studied. Crucial to understanding this connection is the idea that concepts can be intensionally represented in terms of properties of geometric extension, though significantly not the simple geometric property of part-whole inclusion. I go on to provide an explanation for how Leibniz could maintain the metaphysical priority of the intensional interpretation while (...) holding that logically the intensional and the extensional stand in strictly inverse relation to each other.

Diotima's Children is a re-examination of the rationalist tradition of aesthetics which prevailed in Germany in the late seventeenth and eighteenth century.

This paper reexamines the historical debate between Leibniz and Newton on the nature of space. According to the traditional reading, Leibniz (in his correspondence with Clarke) produced metaphysical arguments (relying on the Principle of Sufficient Reason and the Principle of Identity of Indiscernibles) in favor of a relational account of space. Newton, according to the traditional account, refuted the metaphysical arguments with the help of an empirical argument based on the bucket experiment. The paper claims that Leibniz’s and Newton’s arguments (...) cannot be understood apart from the distinct dialectics of their respective positions vis-à-vis Descartes’ theory of space and physics. Against the traditional reading, the paper argues that Leibniz and Newton are operating within a different metaphysics and different conceptions of “place,” and that their respective arguments can largely remain intact without undermining the other philosopher’s conception of space. The paper also takes up the task of clarifying the distinction between true and absolute motion, and of explaining the relativity of motion implied by Leibniz’s account. The paper finally argues that the two philosophers have different conceptions of the relation between metaphysics and science, and that Leibniz’s attempt to base physical theory on an underlying metaphysical account of forces renders his account of physics unstable.

THE CLOSE CONNECTION BETWEEN mathematics and philosophy has long been recognized by practitioners of both disciplines. The apparent timelessness of mathematical truth, the exactness and objective nature of its concepts, its applicability to the phenomena of the empirical world—explicating such facts presents philosophy with some of its subtlest problems. We shall discuss some of the attempts made by philosophers and mathematicians to explain the nature of mathematics. We begin with a brief presentation of the views of four major classical philosophers: (...) Plato, Aristotle, Leibniz, and Kant. We conclude with a more detailed discussion of the three “schools” of mathematical philosophy which have emerged in the twentieth century: Logicism, Formalism, and Intuitionism. (shrink)

In his New Essays on Human Understanding, Leibniz presents an extended critical commentary on Locke’s Essay Concerning Human Understanding. Leibniz read some of Locke’s work in English and then, a few years later, the whole of it in French, a language in which he was more comfortable. Over a period of about two further years, on and off, he wrote his New Essays, which he finished at about the time Locke died and which was not published until about half a (...) century after Leibniz’s death. (He left them unpublished partly because they had been motivated by a hope of getting Locke to reply, and Locke’s death put an end to that; though his character made it a forlorn hope in any case.) The New Essays has been an important work: for one thing, Kant read it on its first appearance, and scholars say that this was a decisive event in his philosophical development. Anyway, given that this is one of Leibniz’s only two philosophical works of substantial book length, in all the torrent that poured from his pen, and given also that it is focused - critically but with respect and careful attentiveness - on the greatest classic of English philosophy, it is surprising that the New Essays had to wait until 1981 for a usable English translation.1 In 1896 there was published a sort of translation by A. G. Langley;2 but it is inaccurate far beyond the bounds of normal incompetence, as well as being grimly unreadable for stylistic reasons. As Chesterton once said about The Origin of Species, it is surprising how many people think they have read it, but I'll bet that nobody alive has slogged through the Langley version from cover to cover. It is a pity that the work was not decently available in English for nearly three centuries, because even for those who can read the French of, say, Descartes, Leibniz’s French is difficult. He reserved his native German for writings on history and politics, using French and Latin for philosophy and mathematics; presumably French was chosen for the New Essays because Leibniz wanted to respond to a popular work by a popular work..

Leibniz defends concurrentism, the view that both God and created substances are causally responsible for changes in the states of created substances. Interpretive problems, however, arise in determining just what causal role each plays. Some recent work has been revisionist, greatly downplaying the causal role played by created substances—arguing instead that according to Leibniz only God has productive causal power. Though bearing some causal responsibility for changes in their perceptual states, created substances are not efficient causes of such changes. This (...) paper argues against such revisionism; not only was Leibniz a consistent advocate of concurrentism (at least in his “mature” years), but also his account of concurrentism involves both God and created substances asefficient causes of the changes in the states of created substances.
