Soul substance (jīva dravya) is ubiquitous but unseen. Driving force within each one of us, it has been, since time immemorial, a subject matter of research by philosophers, religious leaders and laity. Still, ambiguity and misconceptions prevail as regard its real nature. Some negate the existence of soul and attribute consciousness to the union of four basic substances – earth (prthvī), water (jala), fire (agni), and air (vāyu); death leads to its annihilation. Some believe it to be (...) momentary, devoid of self-existence. Still others consider it a product of illusion (māyā) or ignorance (avidyā) as all objects are manifestations of Brahma; only the one eternally undivided Brahma exists. All such conceptions are based on absolutism like: existence (bhāvaikānta) and non-existence (abhāvaikānta), non-dualism (advaita-ekānta) and separateness (prthaktva-ekānta), and permanence (nityatva-ekānta) and momentariness (ksanika-ekānta). Jaina epistemology goes beyond the superficial and examines objects of knowledge from all possible points of view. It asserts that the entity (dharmī) and its attributes (dharma) are neither absolutely dependent (āpeksika) nor absolutely independent (anāpeksika). Only an entity which has general (sāmānya – concerning the substance, dravya) and particular (viśesa – concerning the mode, paryāya) attributes can be the subject of knowledge. Substance without its modification and modification without its substance cannot be the subject of valid knowledge; only their combination can be the subject of knowledge. (shrink)

Unger has recently argued that if you are the only thinking and experiencing subject in your chair, then you are not a material object. This leads Unger to endorse a version of Substance Dualism according to which we are immaterial souls. This paper argues that this is an overreaction. We argue that the specifically Dualist elements of Unger’s view play no role in his response to the problem; only the view’s structure is required, and that is available to Unger’s (...) opponents. We outline one such non-Dualist view, suggest how to resolve the dispute, respond to some objections, and argue that ours is but one of many views that survive Unger’s challenge. All these views are incompatible with microphysicalism. So Unger’s discussion does contain an insight: if you are the only conscious subject in your chair, then microphsyicalism is false. Unger’s mistake was to infer Substance Dualism from this; for microphysicalism is not the only alternative to Dualism. (shrink)

‘The soul hypothesis’ enjoys near unanimous support in the general population. Among philosophers and scientists, however, belief in the soul is far less common. The purpose of this essay to explain why many philosophers and scientists reject the soul hypothesis and to consider what the non-existence of the soul would entail.

This article deals with an argument reported by Razi (d. 1210) that attempted to undermine the immaterialist position about human nature. After some introductory remarks and explanation of the conceptual background, the article analyses the structure of the argument, with special attention to the idea of soul-switching.’ Some comparisons are made between the argument reported by Razi and a number of arguments from modern and contemporary eras of philosophy. One section is devoted to the critique of the argument and (...) its conceptual basis. This article shows that the argument reported by Razi is a methodological antecedent of a family of contemporary epistemological arguments against substance dualism. It is also shown that discussion of the argument could be useful to highlight a weakness in some, but not all, versions of immaterialism about human nature. (shrink)

This paper explores the development of Leibniz’s metaphysics of the Incarnation in the context of his philosophy. In particular it asks to what extent Leibniz’s repeated endorsement of the traditional analogy between the union in humankind of soul (mind) and body, and the union in Christ of divine and human natures, could be accommodated by his more general metaphysical doctrines. Such an investigation highlights some of the deepest commitments in Leibniz’s theory of substance as well as detect in (...) it some unresolved tensions. The paper comes to the conclusion that puzzling points of Leibniz’s metaphysics of the Incarnation, rather than being problems specific to his theology, uncover tensions in his theory of substance as such – tensions converging on the vexed question of whether there can or cannot be genuine corporeal substances in Leibniz’s mature philosophy.

At a 2011 meeting of the Society of Christian Philosophers, N. T. Wright offered four reasons for rejecting the existence of soul. This was surprising, as many Christian philosophers had previously taken Wright's defense of a disembodied intermediate state as a defense of a substance dualist view of the soul. In this paper, I offer responses to each of Wright's objections, demonstrating that Wright's arguments fail to undermine substance dualism. In so doing, I expose how popular (...) arguments against dualism fail, such as dualism is merely an unwarranted influence of Greek culture on Christianity, and substance dualism is merely a soul-of-the-gaps hypothesis. Moreover, I demonstrate that Wright himself has offered a powerful reason for adopting substance dualism in his previous works. In conclusion I offer a view that explains why the human soul needs a resurrected body. (shrink)

The piece of wax takes on the form of the seal; but this occurs in a way that is largely indifferent to the particular constitution of the seal. Similarly, Aristotle says, ‘the sense is affected by what is coloured or flavoured or sounding, but it is indifferent as to what in each case the substance is’. We show that Brentano takes this Aristotelian account of the relation between sense and its objects as the basis for his theory of mind (...) in the Psychology from an Empirical Standpoint. (shrink)

Many contemporary philosophers of mind disagree with substance dualism, saying that despite the failure of physical theories of mind, substance dualism cannot be advocated, because it faces more serious problems than physical theories, lacking compatibility with philosophical arguments and scientific evidence. Regardless of the validity of the arguments in support of substance dualism, it is demonstrated in this article that this theory is coherent, with no philosophical or scientific problems. The main arguments of opponents of substance (...) dualism are explained and criticized in this respect. Based on this, it becomes clear that the interaction of soul and body has a reasonable philosophical explanation, the problem of the pairing of soul and body, although it may not have a scientific explanation, it has a philosophical and theological solution, the principle of the physical causal closure lacks conclusive reasons and cannot reject the existence of the soul, the existence of the soul does not contradict the theory of evolution, the dependence of the soul on the brain is compatible with its independence, and finally, the principle of simplicity does not make any problem for accepting the substance dualism.

Friedrich Nietzsche’s criticism towards the substance-concept „I“ plays an important role in his late thought, and can be properly understood by making reference to the 19th century debate on the scientific psychology. Friedrich Lange and Ernst Mach gave an important contribution to that debate. Both of them developed the ideas of Gustav Fechner, and thought about a „psychology without soul“, i.e. an investigation that gives up with the old metaphysics of substance in dealing with the mind-body problem. (...) In this paper I shall deal with both Lange and Mach (whose writings has been read by Nietzsche), in order to shed some light on Nietzsche’s rejection of the „I“ in philosophy. (shrink)

This article aims to review the standard objections to dualism and to argue that will either fail to convince someone committed to dualism or are flawed on independent grounds. I begin by presenting the taxonomy of metaphysical positions on concrete particulars as they relate to the dispute between materialists and dualists, and in particular substance dualism is defined. In the first section, several kinds of substance dualism are distinguished and the relevant varieties of this kind of dualism are (...) selected. The remaining sections are analyses of the standard objections to substance dualism : It is uninformative, has troubles accounting for soul individuation, causal pairing and interaction, violates laws of physics, is made implausible by the development of neuroscience and it postulates entities beyond necessity. I conclude that none of these objections is successful. (shrink)

“Substance-in-relation” is W. Norris CLARKE’s own contribution to the thought of Aquinas on the metaphysics of the human person. Clarke argues that a dynamic notion of the human person with an intrinsic dynamic substance and a primordial relation is implicit in the thought of Aquinas and he wants to make them explicit. His approach was to “creatively retrieve” this intrinsic dynamic notion in Aquinas and to “complete” it with the rich relational notion that was well-developed by some contemporary (...) existential phenomenologists, personalists and psychotherapists. He argues that the human person possesses dyadic structures of substance and relation that are equally primordial. So, for him, “to be” a human person is to be a “substance-in-relation.” This implies that substance alone, even though dynamic, is insufficient to constitute a human person. In this way, Clarke seems to differ from Aquinas who argued that the human person is a substance composed of body and soul. In fact, the conclusions reached by Clarke on the basic seminal ideas of the human person leaned more towards the thoughts of the above contemporary thinkers than that of Aquinas, suggesting that he must have departed significantly from St. Thomas. This raises doubt about to what extent he retrieved the thought of Aquinas. This research, therefore, is an attempt to furnish some elements that would help the reader to evaluate whether Clarke’s work could be considered more as a “creative retrieval” or more as a “creative completion” of the thought of Aquinas. The method employed here is to trace the background to the formation of Clarke’s thought. There is also an analysis of his thought. This is followed by a critical analysis of his notion of human substance and of relation. Finally, certain elements are furnished to help the reader in this evaluation. (shrink)

Paper given at the 20th Biennial Meeting of the Hegel Society of America, University of South Carolina, October 24-26, 2008 -/- The local problem of the soul-body relation can be grasped only against the global background of the relation between Nature and Spirit. This relates to Hegel's naturalism: the idea that there is one single reality - living reality - and different levels of description of it. This implies, moreover, that it is possible to ascribe some form of naturality (...) also to the social body of institutionalized ethical life. Hegel’s position can thus be characterised as a kind of aristotelian social naturalism: this, at bottom, is the combined meaning of the Hegelian theses that soul is the substance of Spirit, and habit its universal form.

The link between human nature and human flourishing is undeniable. "A healthy tree cannot bear bad fruit, nor can a diseased tree bear good fruit" (Matt. 7:18). The ontology of the human person will, therefore, ground the nature of human flourishing and thereby sanctification. Spiritual formation is the area of Christian theology that studies sanctification, the Spirit-guided process whereby disciples of Jesus are formed into the image of Jesus (Rom. 8:28-29; 2 Cor. 3:18; 2 Peter 3:18). Until the nineteenth century, (...) there was an overwhelming consensus among Christian thinkers that some form of mind-body (or soul-body) dualism is true of human beings. Recently, that consensus has eroded, and with it the availability of a shared body of knowledge about spiritual formation. Some Christian physicalists argue that dualism is incompatible with central elements of spiritual formation. Neuroscientist Warren Brown and psychologist Brad Strawn offer the only substantive account of spiritual formation from the view of Christian physicalism and its accompanying objections to dualism. It is on their arguments that this chapter focuses. We argue that Brown and Strawn fail to support their incompatibility thesis. Additionally, we argue that Christian physicalism stands in tension with important philosophical and theological foundations of Christian spiritual formation. In doing so we offer a specific form of dualism, the bodily soul view, and explain how this view illuminates the importance of embodiment, our neurological and social development, and hence the important physical aspects of Christian spiritual formation.

In a series of publications spanning over two decades, William Hasker has argued both that (1) human beings have souls and (2) these souls are not directly created by God but instead are produced by (or “emergent from”) a physical process of some sort or other. By contrast, an alternative view of the human person, endorsed by the contemporary Catholic Church, maintains that (1) human beings have souls but that (2*) each human soul is directly created by God rather (...) than produced by any kind of physical process. Hasker argues that given what we know from evolutionary biology, (2*) is a much less plausible position for believers in souls to take than (2) is. If Hasker is right, then there is a serious tension between the Church’s teaching about the human person and evolutionary biology. In this article, I challenge Hasker’s reasoning. I argue that those who hold the Catholic view that each human soul is directly created by God face no more difficulty reconciling their view with evolutionary biology than those who maintain, as Hasker does, that human souls are instead produced by some kind of physical process.

In the Aristotelian tradition, there are two broad answers to the basic question "What is soul?" On the one hand, the soul can be described by what it does. From this perspective, the soul seems to be composed of various different parts or powers (potentiae) that are the principles of its various actions. On the other hand, the soul seems to be something different, namely, the actual formal principle making embodied living substances to be the kinds (...) of things that they are. Contemporary Aristotelians are split on how to interpret Aristotle: Anna Marmodoro (2013, 18), Thomas Johansen (2012, 81), and most others argue that the soul is nothing but a kind of cluster or group of powers. Rebekah Johnston (2011), however, strongly disagrees and argues that the soul is only the actual principle of embodied substance. Aquinas provides a novel and neglected solution to this problem and would argue that both sides are partly right but that either side is insufficient without the other. (shrink)

In the last decade, there has been a notable upsurge in property (PD) and generic substance dualism (SD). By SD I mean the view that there is a spiritual substantial soul that is different from but variously related to its body. SD includes Cartesian, certain forms of late Medieval hylomorphic (e.g., Aquinas'), and Haskerian emergent SD. Nevertheless, some form of physicalism remains the majority view in philosophy of mind. Several fairly standard objections have been raised against SD, and (...) SDists have been preoccupied with these objections. As a result, a potent objection has not been given the attention it deserves. The purpose of this article is to fill that lacuna by raising the visibility of this objection and providing plausible responses to it. First, I shall clarify the explanatory–impotence challenge and, second, provide defeaters against it. Note that several of the issues to follow apply both to PD and SD. I will focus mostly on SD, but sometimes PD is a part of the discussion in that certain arguments for and against PD indirectly affect SD. When it is important for me to note that either SD or PD is specifically being addressed, I will notify the reader. (shrink)

Catharine Trotter Cockburn’s metaphysics dissolves the necessary relationship between immateriality, immortality and thought. While in her youth this leads her to admit the possibility of thinking matter, in her mature work, it allows her to conceive space as non-thinking immaterial substance that links non-thinking material substance and thinking immaterial substance. To ground this conception of space, she draws on the thesis of the great chain of being. However, the possibility of thinking matter is not consistent with the (...) hierarchy of beings, because within this frame matter occupies the lowest place. My aim is to evaluate whether there is any alternative within Trotter's philosophy to solve this contradiction. -/- La metafísica de Catharine Trotter Cockburn disuelve la relación necesaria entre inmaterialidad, inmortalidad y pensamiento. Mientras que en su juventud esto la lleva a admitir la posibilidad de la materia pensante, en su madurez le permite concebir al espacio como sustancia inmaterial no pensante que oficia como eslabón entre la sustancia material no pensante y la sustancia inmaterial pensante. Para ello, apela también a la tesis de la gran cadena del ser. Sin embargo, la posibilidad de la materia pensante no es consistente con la tesis de la jerarquía de seres, porque en ella la materia ocupa el lugar más bajo. Me propongo estudiar si existe alguna alternativa dentro de la filosofía de Trotter que permita resolver esta contradicción. (shrink)

In The Analysis of Mind (1921), Bertrand Russell stresses the importance of William James’ late neutral monist view of consciousness for the studies in psychology. In so doing, he focuses on a topic whose roots can be traced back to the nineteenth-century European debate on physiology and scientific psychology. In this introductory paper I shall briefly outline the path that, starting from the revival of Kant in the German scientific debate, leads to both Ernst Mach’s and William James’ questioning the (...) value of the I or consciousness as a substance concept.

I seek to explicate the ways in which the soul is deemed immaterial in two main strands of Islamic philosophy, and then consider some arguments for the immateriality of the soul. To do so, I first overview Avicenna’s theory of the spiritual incipience (al-ḥudūth al-rūḥānī) of the soul and his version of substance dualism. I will then discuss Mullā Ṣadrā’s view of the physical incipience (al-ḥudūth al-jismānī) of the soul and how the soul emerges (...) and develops towards immateriality on his account. I then overview and discuss five of the most important arguments presented by these two great Muslim philosophers in favor of the immateriality of the soul. To do so, I will also point out some of the main contemporary physicalistic views of the nature of mind and mental states. I will then argue that arguments for the immateriality of the soul – dealt with here – do not indeed target or challenge any significant versions of contemporary physicalism. Moreover, these arguments involve conflations of epistemological or ontological issues. (shrink)

A review of Joshua Farris's The Creation of Self: A Case for the Soul.

The human soul has been believed to be immaterial and immortal element which exclusively inheres in the human body. Ukpugho ukpong (soul transplant) is an ancient meta-medical science of the Annang and Ibibio people, which is hinged on the belief that the human soul is transcendent and it exclusively inheres in proxy animal; that the soul is mortal, and can be surgically transplanted in the likeness of somatic tissue transplant. This study aimed at carrying out a (...) philosophical critique of this belief in order to determine its significance as a metaphysical concept. It also aimed at critically examining the philosophical as well as sociological discussions on the subject of ukpuho ukpong. The study was discussed on the framework of African concept of mind which holds that the soul has dual nature, namely – the Active Principle and the Quiescent Counterpart. The paper debunks the doctrines of metempsychosis and transmigration as alien to African metaphysics. The method of ordinary language analysis was employed to analyze the concepts ukpong and mbukpong. In conclusion, the paper made the following observations that: the soul is transcendent but perishable substance, the mind has dual nature, the soul does not transmigrate and the science of ukpuho ukpong is not a pseudo-metaphysical concept but was founded on African logic of dualistic mind. The paper notes that the science of ukpuho ukpong is bugged with a number of unresolved philosophical problems. Despite that the paper discovered that the science of ukpuho ukpong can contribute significantly to meta-medicine and sustainable environmental values. (shrink)

‘Niyamasāra’ by Ācārya Kundakunda (circa 1st century BC) is among the finest spiritual texts that we are able to lay our hands on in the present era. The treatise expounds, with authority, the nature of the soul (ātmā) from the real, transcendental point-of-view (niścayanaya). It expounds the essence of the objects of knowledge, and, by the word ‘niyama’, the path to liberation. ‘Niyamasāra’ is the Word of the Omniscient Lord. It has the power to bestow ineffable happiness of liberation (...) that is utterly rid of attachment, without obstruction, eternal, and sense-independent. This happiness is attained by meditating on the perfect-soul-substance which is pristine, and endowed with four qualities of infinite-knowledge, imperishable, indestructible, and indivisible. Worthy men aspiring for supreme happiness who comprehend this Scripture without contradiction of the empirical (vyavahāra) and the transcendental (niścaya) points-of-view are able to adopt conduct that leads their souls to the desired goal. By concentrating on the pure (śuddha) and inseparable (abheda) ‘Three Jewels’ (ratnatraya), eternal happiness appertaining to the perfect-soul-substance is attained. ‘Niyamasāra’ discourses right exertion for the soul and its fruit, the supreme liberation.

Substance dualism has received much attention from philosophers and theologians in contemporary literature. Whilst it may have been fashionable in the recent past to dismiss substance dualism as an unviable and academically absurd position to hold, this is no longer the case. My contention is not so much the merits of substance dualism in general, but a more specified variation of substance dualism. My specific contribution to the literature in this article is that I argue for (...) the viability of pure substance dualism as a more satisfactory option in contrast to compound or composite varieties of substance dualism. I put forth one argument and tease out the implications that make compound dualism less than satisfactory. I conclude that, minimally, more work is required on compound variations of dualism to make it a more appealing and a philosophically satisfactory option. (shrink)

In Galileo's Error, Philip Goff sets out a manifesto for a post-Galilean science of consciousness. Article four of the manifesto reads: 'Anti-Dualism: Consciousness is not separate from the physical world; rather consciousness is located in the intrinsic nature of the physical world.' I argue that there is an important sense of ‘dualism’ in which Goff’s arguments are not only compatible with but entail dualism, and not only dualism but substance dualism. Substance dualism, in the sense I have in (...) mind, is the view that (i) there are two sides to reality, a fundamentally mental side and a fundamentally nonmental side; and (ii) the fundamentally mental side consists of mental substances resembling Cartesian souls. I do not suggest that this is bad news for post-Galilean science of consciousness. My aim is rather to push for a certain view about what a theory of consciousness motivated by Goff’s arguments must look like. (shrink)

I advance a type of conceptualist argument for substance dualism – minimally, the view that we are spiritual substances that have bodies – based on the understandability of what it would be for something to be a spirit, e.g. what it would be for God to be a spirit. After presenting the argument formally, I clarify and defend its various premises with a special focus on what I take to be the most controversial one, namely, if thinking matter is (...) metaphysically possible, it is not the case that we have a distinct positive concept of God's being a divine spirit.

Ātmānuśāsana (commonly spelled as Atmanushasan) by Ācārya Guņabhadra presents profound concepts of the Jaina Doctrine in a form that is easily understood. Remarkable for its poetry and meaning, it expounds that right faith (samyagdarśana) is the cause of merit, and wrong faith of demerit. To have belief in the true nature of substances is right faith. Dharma is the man’s most excellent possession. The conduct that leads to merit is dharma and it results in happiness after destroying misery. Whether happy (...) or miserable, dharma should be the only pursuit of man. True happiness is not the momentary sprinkling of the pleasures of the senses. Long-life, wealth and sound body are obtained from the previously earned merit (puņya). Under the spell of sinful karmas, the man experiences misery. Excellent men with discrimination work hard, incessantly and cheerfully, for the sake of their future lives. The happiness attained through austerity (tapa) can never be attained by craving for wealth. No dust of disgrace ever touches the feet of the man fortified by austerity. The ascetic goes on to perform austerity while protecting his body, for a very long time. Through the power of austerity he vanquishes his natural enemies, like the passions of anger, etc. In the after-life, he automatically and speedily attains liberation as the culmination of his human effort.

In this paper we inquire whether Leibniz’s metaphysics of the body has undergone a signifi cant change in the last twenty years of his life. Th is metaphysical conception seems incompatible with the late monadological conclusions. Yet, to explain the body in terms of monadic subordination makes soul and body inseparably united. Far from there being two incompatible ontologies in Leibniz’s late philosophy, we fi nd a seamless connection between what is monadic and what is organic: a single point (...) of view that includes the order of bodies and that of monadic substrates, and a system that accounts for all levels of reality. Ultimately, our topic is whether Leibniz was a realist metaphysician, an idealist one, or whether in the philosophy of his maturity he tried to reconcile the two tendencies. résUMé : Dans cette étude la question est de savoir si la vision de Leibniz sur la métaphysique du corps a subi un changement important dans les vingt dernières années de sa vie. Il s’agit là d’une conception métaphysique qui semble incompatible avec les conclusions monadologiques tardives. Pourtant, expliquer le corps en termes de subordination monadique, rend l’âme et le corps inséparablement unis. Loin d’être deux ontologies incompatibles dans la philosophie de maturité de Leibniz, on y trouve une connexion sans faille entre ce qui est monadique et ce qui est organique : un point de vue unique qui comprendrait l’ordre des corps et celui des substrats monadiques, un système qui rendrait compte de tous les niveaux de la réalité. Finalement, le sujet de discussion consiste à savoir si Leibniz a été un métaphysicien réaliste, un idéaliste, ou bien s’il a essayé de réconcilier les deux tendances dans sa philosophie de la maturité.

Pańcāstikāya-samgraha or Pańcāstikāya-sāra (known briefly as Pańcāstikāya and spelled commonly as Panchastikay) is one of the four most important and popular works of Ācārya Kundakunda (circa first century B.C.), the other three being Samayasāra, Pravacanasāra and Niyamasāra. The original text is in Prakrit language and contains a total of 173 verses (gāthā). Pańcāstikāya means ‘five-substances-with-bodily-existence’ and these are: the soul (jīva), the physical-matter (pudgala), the medium-of-motion (dharma), the medium-of-rest (adharma), and the space (ākāśa). These five substances collectively constitute the (...) universe-space (loka). Outside this universe-space (loka) is the infinite non-universe-space (aloka), comprising just the pure space (ākāśa). The substance-of-time (kāla dravya) which renders assistance to all substances in their continuity of being through gradual changes is not an ‘astikāya’ since it occupies a single space-point and, therefore, does not possess the characteristic of body (kāya). Pańcāstikāya-samgraha expounds the Jaina metaphysics – the philosophy of being and knowing – including the nature of the pure soul-substance (jīvāstikāya) which is integral to the seven realities (tattva), the nine objects (padārtha), and the six substances (dravya). While the substance (dravya) never leaves its essential character of existence (sattā), it undergoes origination (utpāda), destruction (vyaya) and permanence (dhrauvya). There is inseparable association between the qualities (guņa) and the substance (dravya). The discussion relies on the ‘doctrine of conditional predication’ (syādvāda) and the ‘seven-nuance system’ (saptabhańgī), as expounded by Lord Jina. (shrink)

Through an analysis of a part of Thomas’ arguments on the rational soul’s subsistence, the article exposes the reasons why it is necessary and possible to affirm that the human soul is a substance in its proper sense, even if it does not have the entire human essence when it subsists apart from the body. Thus the article intends to answer a question raised by B.C. Bazán. The analysis is articulated applying the principle nihil agit nisi secundum (...) quod est actu in different ways in order to make explicit the reason why the soul is the suppositum of intellectual operations and faculties and therefore a substance; then the article reaffirms that the substantial form’s definition is related to the act of being in order to distinguish the “virtual” way in which any substantial form has the entire species, from the “real” way in which any substance has an entire substantial essence.

According to the Christian doctrine of bodily resurrection, human persons will have an embodied existence in eternity. Many Christian materialists, especially Lynne Rudder Baker, Trenton Merricks, and Kevin Corcoran, argue that the doctrine of bodily resurrection creates serious problems for substance dualism (dualism). These critiques argued that bodily resurrection is made trivial by dualism, that dualism makes it difficult if not impossible to explain why we need to be embodied, or that dualism should be rejected as bodily resurrection is (...) better accounted for by a materialist view. As of yet, there has been no systematic analysis of these arguments in the literature. This paper fills that gap and argues that each of these objections to dualism fail. In making these arguments I make use of neo-Aristotelian metaphysics to provide a theory of embodiment for substance dualism. Accordingly, the body is a complex structural mode of the soul. The essence of the soul is the internal efficient cause and teleological guide of the functions and structure of the body. As such, the body is an ensouled physical structure, not a mere physical machine, but has both physical and non-physical aspects. (shrink)

Ācārya Kundakunda’s (circa 1st century BCE) ‘Samayasāra’ is among the most profound and sacred expositions in the Jaina religious tradition; it is perhaps the finest spiritual texts that we are able to lay our hands on in the present era. The original text is in Prakrit language and contains a total of 415 verses (gāthā). ‘Samayasāra’ is the exposition of the Pure (śuddha) ‘Self’ or ‘Soul’. It is the exposition, from the transcendental point-of-view (niścaya naya), of the ‘Real Self’ (...) or it is the ‘Essence of the Soul’. The assertions that the soul (jīva) gets bound to the karmic matter (dravya-karma) or that it does not get bound to the karmic matter are made from different points-of-view (naya). But that which transcends all points-of-view is the ultimate truth, the ‘samayasāra’, absolute and pure soul-substance. (shrink)

The main objective of this work was to produce a scientifically reasonable definition of God. The rationale was to generate a definition for filling a small part of the spiritual vacuum of the 21st century and thus initiate a new understanding of the Intelligence that permeates the cosmos with mystery, love, order, direction and morals. This resulted in the following definition: “God may be a-humanly incomprehensible-eternal cosmic existence, intimately related to the endlessness of space, to the nature of the deepest (...) common substance of matter and energy, to this common substance’s unceasing motion responsible for time, and to the basic laws of their allness, letting love transform this allness to an ordered Multiverse with a Soul: the—scientifically approachable—Soul of Multiverse inspired to guard these laws and equip their order with direction and morals while imbuing the cosmos with the potential of lives evolving, at the right spatial and temporal distances, to embrace the sense of the divine, thus justifying the existence of God.” The likely neural circuitry for sensing God in the human brain was identified as a network for spiritual data flow across the conscious and subconscious layers of the association cortical cognitive system exchanging data with the prefrontal cortical Self-Ken and modulated by inputs from the emotional and motivational systems of the brain. To study this mental process, the design of a God-Experience Monitor was also developed: a comfortably wearable combination of EEG and audiovisual-recorders tailored to at least partially capture the individual experiences of God anytime and at the very “genius loci” of such experiences.

Ācārya Pūjyapāda’s (circa 5th century CE) Samādhitantram is a spiritual work consisting of 105 verses outlining the path to liberation for the inspired soul. Living beings have three kinds of soul – the extroverted-soul (bahirātmā), the introverted-soul (antarātmā), and the pure-soul (paramātmā). The one who mistakes the body and the like for the soul is the extroverted-soul (bahirātmā). The extroverted-soul spends his entire life in delusion and suffers throughout. The one who entertains (...) no delusion about psychic dispositions – imperfections like attachment and aversion, and soul-nature – is the introverted-soul (antarātmā). The knowledgeable introverted-soul disconnects the body, including the senses, from the soul. The one who is utterly pure and rid of all karmic dirt is the pure-soul (paramātmā). Samādhitantram expounds the method of realizing the pure-soul, the light of supreme knowledge, and infinite bliss. Realization of the pure-soul is contingent upon discriminatory knowledge of the soul and the non-soul, and meditating incessantly on the pure-soul, rejecting everything that is non-soul. Samādhitantram answers the vexed question, ‘Who am I?’ in forceful and outrightly logical manner, in plain words. No one, the ascetic or the householder, can afford not to realize the Truth contained in the treatise, comprehend it through and through, and change his conduct accordingly. (shrink)

According to the AI ensoulment hypothesis, some future AI systems will be endowed with immaterial souls. I argue that we should have at least a middling credence in the AI ensoulment hypothesis, conditional on our eventual creation of AGI and the truth of substance dualism in the human case. I offer two arguments. The first relies on an analogy between aliens and AI. The second rests on the conjecture that ensoulment occurs whenever a physical system is “fit to possess” (...) a soul, where very roughly this amounts to being physically structured in such a way that the system can meaningfully cooperate with the operations of the soul.

According to Nicole Oresme (c. 1320–1382), human beings, unlike all other animals, consist of two substances: a thinking substance and a sensing substance.

The paper (...) also considers some moments of ambivalence in Oresme’s presentation, as well as unresolved difficulties, several of which have theological as well as philosophical implications.

This study shows that Aristotle’s introduction of the concept of substance represents a caesura in the history of ontology. The study takes two values for substance into consideration, which are a) substance as an organism (as a biological entity) and b) substance as essence, nature, form of an organism. Substances as organisms are biological concretized properties. Substance as form is the soul directing the organism and the development of the organism; the soul is (...) both the principle of life of the organism and the program which is realized in the organism. The substance as an organism is assigned the central position in Aristotle’s ontology: the organism is not reduced to forces or factors which should have an ontological primacy over the organism; the principle of life and activity of every organism is put into the biological entity and it is not identified with factors that lie outside the organism.

In this essay, I discuss the standard objections to substance dualism and conclude that they are far less formidable than is usually supposed.

Mereological nihilists hold that composition never occurs, so that nothing is ever a proper part of anything else. Substance dualists generally hold that we are each identical with an immaterial soul. In this paper, I argue that every popular objection to substance dualism has a parallel objection to composition. This thesis has some interesting implications. First, many of those who reject composition, but accept substance dualism, or who reject substance dualism and accept composition, have some (...) explaining to do. Secondly, one popular objection to mereological nihilism, one which contends that mereological nihilism is objectionable insofar as it is incompatible with the existence of people, is untenable.

Leibnizian metaphysics is traditionally held to be idealistic. It means that reality is composed of soul-like substances whereas material bodies are mere phenomena. The traditional interpretation presupposes that Leibniz’s view has not changed during the mature period (from 1683 onward). Some commentators have recently challenged this view. They claim that either Leibniz (despite inconsistency) was both a realist and an idealist (Hartz), or changed his view on the nature of substance (Garber). The aim is to defend the traditional (...) interpretation and to reply to the arguments by realist commentators. (shrink)

In the part of the first Critique known as “The Paralogisms of Pure Reason” Kant seeks to explain how even the most acute metaphysicians could have arrived, through speculation, at the ruefully dogmatic conclusion that the self (understood as the subject of thoughts or "thinking I") is a substance. His diagnosis has two components: first, the positing of the phenomenon of “Transcendental Illusion”—an illusion, modelled on but distinct from, optical illusion--that predisposes human beings to accept as sound--and as known (...) to sound--certain in fact flawed arguments for substantive theses about the nature of the self; second, the identification of the fallacy we commit when we succumb to this illusion. It is explained how these two elements combine to produce a central instance of (what Kant sees as) dogmatic speculative metaphysics, namely, the doctrine that the self is a substance in the sense of a necessarily non-inhering subject of inherence. It is argued that Kant has a novel, ingenious, and even somewhat plausible account of the route by which the rational psychologist arrives--or might arrive--at this view, an account that involves identifying a rather deep-rooted confusion about the very nature of conceivability.

In this paper the author will assess Plato’s tripartite psychology in the light of his metaphysical account of μέγιστα γένη and One and Many, in order to further clarify the structure of his “dualism”. By doing so, the author will try to show that the tripartition is not a metaphysical conundrum of Plato’s thought and that it cannot be read in the light of Cartesian substance dualism, which is a noticeable approach in contemporary discussions. Aside of that, Plato and (...) Descartes are often understood as the main advocates of the substance dualism. Since the author finds the approach misleading, the aim of the paper is to point out the fundamental differences between the two, foremost by paying attention to the role of body in conceptual determination of soul.

I argue that in the Phaedo, Plato maintains that the soul is located in space and is capable of locomotion and of interacting with the body through contact. Numerous interpreters have dismissed these claims as merely metaphorical, since they assume that as an incorporeal substance, the soul cannot possess spatial attributes. But careful examination of how Plato conceives of the body throughout his corpus reveals that he does not distinguish it from the soul in terms of (...) spatiality. Furthermore, assigning spatial attributes to the soul plays an important role in Plato’s account of the relation of body and soul. (shrink)

In De Anima I 4, Aristotle describes the intellect (nous) as a sort of substance, separate and incorruptible. Myles Burnyeat and Lloyd Gerson take this as proof that, for Aristotle, the intellect is a separate eternal entity, not a power belonging to individual humans. Against this reading, I show that this passage does not express Aristotle’s own views, but dialectically examines a reputable position (endoxon) about the intellect that seems to show that it can be subject to change. The (...) passage’s argument for the indestructibility of intellect via an analogy to perception does not fit with Aristotle’s own views. Aristotle thinks that perception operates via bodily organs, but denies this of understanding. He also requires separability from the body for indestructibility, something this analogy rules out. However, Aristotle’s Platonist interlocutors may well endorse such an argument. My dialectical interpretation best resolves the interpretative difficulties and explains its place in the larger context, Aristotle’s discussion of Platonist views on the soul. Aristotle presents a challenge to his insistence that the soul is subject to change, dialectically resolves that challenge, and then ends by reserving the right to give a different account of the intellect.

Henry More was an expounder of Cambridge Platonism, as he largely relied on a Platonicinspired standpoint in pursuing his aims: the demonstration of the immortality of soul, the critique of atheism and religious enthusiasm. He maintains that soul emanates from God (being therefore not created and pre-existing body) and argues for the existence of a spirit of nature as means to explain natural phenomena, which cannot be accounted for only in mechanical terms. Moreover, he argues for the extended (...) nature of God and spirits, as only in this way they can act on the world. Accordingly, More rejects Descartes’s theory of immaterial substance, but relies on his ontological argument provide a demonstration of the existence of God. His critique to enthusiasm (especially that one characterizing Neoplatonic mysticism) is medical, as he distinguishes between a rational, religious inspiration, and a melancholic one. (shrink)

Starting from the early treatise "On Being and Essence", I review issues concerning substances composed of matter and form: their hylomorphic composition, individuation, essence as part and as whole, and the analogy between genus/difference and matter/form. Then I discuss substances separated from matter, which may range from human souls and angels (or intelligences) to God. I then turn to Aquinas's later 'Summa Theologica', where he argues that in the end God cannot possibly belong to the category of substance and (...) discuss possible reasons for Aquinas conflicting accounts on this question.

Considered in light of the reader’s expectation of a thoroughgoing criticism of the pretensions of the rational psychologist, and of the wealth of discussions available in the broader 18th century context, which includes a variety of proofs that do not explicitly turn on the identification of the soul as a simple substance, Kant’s discussion of immortality in the Paralogisms falls lamentably short. However, outside of the Paralogisms (and the published works generally), Kant had much more to say about (...) the arguments for the soul’s immortality as he devoted considerable time to the topic throughout his career in his lectures on metaphysics. In fact, as I show in this paper, the student lecture notes prove to be an indispensable supplement to the treatment in the Paralogisms, not only for illuminating Kant’s criticism of the rational psychologist’s views on the immortality of the soul, but also in reconciling this criticism with Kant’s own positive claims regarding certain theoretical proofs of immortality.

In an earlier paper in Theoria, I discussed an argument based on the idea of “soul-switching” that attempted to undermine the immaterialist account of human beings. The present paper deals with a parity argument against that argument in which the idea of “body-switching” plays a pivotal role. I call these two arguments, that have been reported by Razi (d. 1210), respectively “the soul-switching argument” and “the body-switching argument”. After some introductory remarks, section 2 of the paper describes the (...) structure of the latter argument. Section 3 considers some philosophical discussions in the ancient, modern, and contemporary eras in which the idea of body-switching (or some similar conception) plays a major role. In the following section 4, some criticisms of the argument are discussed and a general response that is meant to cover a broad range of objections is considered. This paper shows that the body-switching argument reported by Razi is a methodological antecedent of several contemporary arguments in defence of substance dualism. (shrink)

In early modern times it was not uncommon for thinkers to tease out from the nature of God various doctrines of substantial physical and metaphysical import. This approach was particularly fruitful in the so-called beast-machine controversy, which erupted following Descartes’ claim that animals are automata, that is, pure machines, without a spiritual, incorporeal soul. Over the course of this controversy, thinkers on both sides attempted to draw out important truths about the status of animals simply from the notion or (...) attributes of God. Automatists – led by Nicolas Malebranche and Antoine Dilly – developed six such arguments, appealing to divine justice, providence, economy, glory (twice) and wisdom, while opponents to animal automatism developed two arguments, appealing to divine wisdom and goodness. In this article I shall examine the substance of all eight of these arguments, along with their origins, patronage, and variations, and the objections they elicited from opponents, with the aim of determining their suitability for use in contemporary debates about animal sentience and consciousness, and hence their relevance for contemporary philosophers.

Friedrich Nietzsche's criticism towards the substance-concept «I» plays an important role in his late thought, and can be properly understood by making reference to the 19th century debate on the scientific psychology. Friedrich Lange and Ernst Mach gave an important contribution to that debate. Both of them developed the ideas of Gustav Fechner, and thought about a «psychology without a soul», i.e. an investigation that gives up with the old metaphysics of substance in dealing with the mind-body (...) problem. In this paper I shall deal with Lange's and Mach's view of the I/soul, in order to shed some light on Nietzsche's rejection of the «I» in philosophy. (shrink)
