This research will argue about which theory of mind between Searle’s and Dennett’s can better explain human consciousness. Initially, distinctions between dualism and materialism will be discussed ranging from substance dualism, property dualism, physicalism, and functionalism. In this part, the main issue that is tackled in various theories of mind is revealed. It is the missing connection between input stimulus (neuronal reactions) and behavioral disposition: consciousness. Then, the discussion will be more specific on Searle’s biological naturalism and Dennett’s multiple drafts (...) model as the two attempted to answer the issue. The differences between them will be highlighted and will be analyzed according to their relation to their roots: dualism and materialism. The two theories will be examined on how each answer the questions on consciousness. (shrink)

The theistic doctrine of creation highlights the significance of the world's dependence on God. For this doctrine, a variety of justifications have been offered based on the ontological and epistemological commitments of a philosopher or theologian. In this dissertation, I defend the thesis that the theistic doctrine of creation is strongly justified when on the one hand the integrity of nature is established by affirming causal necessity while on the other hand the sovereignty of God is maintained by affirming divine (...) simplicity, eternity, and immutability. To construct my argument, in the first chapter, I examine the Aristotelian roots of causal necessity and its development by Avicenna. I also consider objections to causal necessity raised by Hume and al-Ghazālī and some contemporary objections by David Lewis. In the second chapter, I identify three competing theses to explain the integrity of nature, namely, the regularism, the extrinsic necessitarianism, and the intrinsic necessitarianism. I conclude that the intrinsic necessitarianism is the strongest among them. In the third chapter, I make a case for the sovereignty of God by exploring the limits of the concept of the theistic God and claim that sovereignty is conditional on immutability, simplicity, and eternity, which qualify the divine attributes of knowledge, power, and goodness. In the last chapter, after analyzing strengths and weaknesses of theistic accounts of creation, I propose an account of ontological dependence by extending Avicenna's account of creation, which consists in God's conferral of existence, to His sustaining activity at all times during which an object endures.

In this dissertation, I develop and defend a model of causation that allows for dualist mental causation in worlds where the physical domain is physically complete. In Part I, I present the dualist ontology that will be assumed throughout the thesis and identify two challenges for models of mental causation within such an ontology: the exclusion worry and the common cause worry. I also argue that a proper response to these challenges requires a thoroughly lightweight account of causation, i.e. an (...) account that allows for causes to be metaphysically distinct from the phenomena that produce or physically necessitate their effects. In Part II, I critically evaluate contemporary responses to these challenges from the philosophical literature. In particular, I discuss List and Stoljar’s criticism of exclusion worries, Kroedel’s alternative dualist ontology, concerns about the notion of causal sufficiency, and Lowe’s models of dualist mental causation. I argue that none of these proposals provide independent motivation for a thoroughly lightweight account of causation and therefore leave room for improvement. In the first four chapters of Part III, I develop a thoroughly lightweight model of causation, which builds on interventionist approaches to causation. First, I explain how so-called ‘holding fixed’-requirements in standard interventionist accounts stand in the way of dualist mental causation. I then argue that interventionist accounts should impose a robustness condition on causal correlations and that, with this condition in place, the ‘holding fixed’-requirements can be weakened such that they do allow for dualist mental causation. I dub the interventionist model with such weakened ‘holding fixed’-requirements ‘insensitive interventionism’, argue that it can counter the exclusion worry as well as the common cause worry, and explain under which circumstances it would predict there to be dualist mental causation. Importantly, these circumstances might, for all we know, hold in the actual world. In the final three chapters of Part III, I defend insensitive interventionism against some objections. I consider the objection that causation must be productive, the objection that causes must physically necessitate their effects, and the objection that insensitive interventionism is too permissive. I respond by drawing from the literature on causation by absences and on the relation between causation and fundamental physics. Overall, insensitive interventionism performs as well as standard interventionist accounts. I conclude that insensitive interventionism is a credible model of causation. (shrink)

Fidelity to the Cartesian philosophy requires a defense of dualism as well as mind-body union and interaction, all the while keeping to some form of the causal likeness principle. Each of these positions are ones that Descartes maintained throughout his writings. Yet, successors and scholars alike have noted the inconsistencies that arise from defending these views conjointly and have argued that one or more of them should be abandoned. Even the first generation of Cartesian successors whose fidelity to the Cartesian (...) principles was especially steadfast, such as Louis de la Forge, have been interpreted and characterized as giving up causal interactionism and wittingly or unwittingly embracing occasionalism. In my dissertation project, I have made mind-body not body-body cases the starting point of the inquiry into cartesian causal interactionism and from there developed a general model of interaction. This goes against the scholarly norm of focusing on the body-body cases to develop a model that then cannot explain how the mind-body cases work. This is not a minor change in point of view, but rather, requires a paradigm shift in cartesian studies, particularly with respect to understanding mind-body union and interaction. Further supporting the needed paradigm shift in our reading of La Forge is that in his account of union criteria we discover that mind-body union is the true union and that body-body unions are considered such only by extension. As such the case of mind-body union should be taken as the exemplar case and not body-body. According to La Forge, mind and body are linked via the relative attribute of will and share a relationship of mutual and reciprocal dependence. Union is not based on a spatial relation. The union is a hybrid mode – a way of being of the two substances if and when they stand in such a relation to one another. While, the union provides the commonality needed to bridge the gap of what two distinct substances have in common it does not provide the explanation of how mind and body interact. Operationalizing the union in terms of mutual and reciprocal dependence requires further explanation. La Forge explains that mind and body are secondary causes. The causal model of interaction of mind and body is one in which these particular causes and their relation of mutual and reciprocal dependence allows for the action of the one to bring about the effect in the other. The body’s movements stimulate thoughts in the mind and the mind’s thoughts direct movements in the body. There is a bi-directional causal interaction. Furthermore, by coupling La Forge’s account of union and interaction with that of Nadler’s proposed occasional causation model we find that mind and body both have causal agency in the weaker secondary sense. Both substances have the power to determine and direct motion, albeit neither mind nor body create motion per se. La Forge establishes a key distinction between universal and particular causes, which then grounds his subsequent attribution of secondary causal power to wills – to direct the movements of bodies, and to bodies in virtue of their modes of configuration – to direct the movement of other bodies. While, God is the universal and efficient cause that creates minds, bodies, and motion, He has minimal involvement in the particular determinations of volitions and movements. He imparts power to His creatures to determine motion. God conserves the world and the laws set by Him in the form of three laws of motion and seven laws of union. However, finite substances such as mind and body also have force, albeit not in the same sense as God does as the universal and total cause, but rather as particular secondary causes that have autonomy and can determine the direction and local quantity of motion. Thus, La Forge explains how both mind-body and body-body interactions are genuine causes, i.e., non-occasionalistic. Accordingly, in keeping with Cartesian philosophy La Forge maintains dualism, and provides an account of union and an account of interaction that is not occasionalistic. Both mind-body and body-body interaction is based on equivocal causation – the effect does not strictly resemble the cause – but both operate through the likenesses of relations of union, mutual dependence and proximity respectively. Thus, La Forge’s causal model that has minds and bodies interacting based on their relation of mutual and reciprocal dependence, and bodies interacting based on their shared mutual proximity and dependence, provides a weaker account of the causal likeness principle. Nonetheless, there is nothing inconsistent with his defense of a weaker notion of likeness that does not demand resemblance. My examination of La Forge’s Treatise on the Human Mind has demonstrated that we can maintain fidelity in our interpretation of Descartes and the Cartesian philosophy that maintains its adherence to dualism while giving an account of union and causal interaction.
