Most famously advocated by René Descartes, substance dualism is the view that minds, which are essentially thinking and consist of mental substance, and bodies, which are necessarily extended and made of material substance, are ontologically separate entities. The material and mental have entirely different natures, so a mind cannot be equivalent to a body. Human beings, therefore, must be mixtures of the two substances. Substance dualists assert that, despite lacking properties in common, mind and body connect through the capacity of each to causally affect the other (Kim 34). While this position may initially appear intuitive and commonsensical, Descartes and subsequent dualists have faced a multitude of challenges concerning mental causation.
In this case, he argues that if the intellect were in a material form, it could be sensitive to only some physical objects. Nevertheless, the non-material form allows individuals to think about anything. In conclusion, both Aristotle and Plato’s are theories of dualism, they just differ in their explanations. Plato seems to maintain that mind and body are the same; however, Aristotle maintains that they are different. They both share the same sentiments that the soul appears in non-material form and hence it cannot be categorized with the other parts of the body.
Non-metaphysical science is limited because it does not reveal the causal nexus and connection between things. It only shows the effect. Non-metaphysical science does not explore the reasons why certain things are as they are or why certain activities happen. Non-metaphysical science is founded on two inconclusive truths. It is based on logic from principles and theories and empirical knowledge from human senses.
The Causal Determinism theory argues against free will by saying that an event is caused by a causal condition that ensures its occurrence. If a causal condition ensures the occurrence of an event, then that event is unavoidable, which would also mean that all events are unavoidable. The theory then states that a person’s actions are events, therefore a person’s actions are unavoidable. The theory concludes that if a person’s actions are unavoidable, then they have no free will over them, which means that people do not have free will. Based on Hume’s theory of empiricism and critique of induction, the first premise of the Causal Determinist theory is not true, disproving the argument that humans do not have free will.
The importance of the wax argument in Descartes meditations go further than explaining the possibility of a mental faculty that allows the body to perceive nature and natural phenomenon.. By so doing, the wax argument as presented allows an individual to create doubt in their mind about their existence or the existence of any other matter. He had doubts about his senses but he discovered that there was a reason to doubt his senses. The purpose of his argument was to create doubt. Sometimes doubt can make us reason and it help us conclude if our experience has some truth to
Thus, for Quine’s version of Holism to be true, all beliefs must be revisable. Analytic knowledge is non-revisable. Therefore, if Quine’s Holism is true, no statement is analytic. In this paper, I will consider, and then reject, a version of Holism that allows for non-revisable analytic statements. I will then argue that any reasonable
Accordingly, he expresses that as a result of his innate thoughts of God, it only makes sense that it be God who "is the reason for this thought". Thus he explicitly states, ' I have no choice but to conclude that the mere fact of my existing is and of there being in me an idea of a
A being that is permeant or immortal and cannot be created or destroyed. Contingent beings are beings that could easily have not existed, their existence is fully dependent on other things happening. Aquinas argued that “there are contingent things, and contingent things can cause other contingent things. Because that would mean that there’s an infinite regress of contingency, and a possibility that nothing might have ever existed. An infinite regress is impossible.
This is an assumption of an external and objective fact that is represented by my internal and subjective representation. It is very difficult to attribute any truth to my perception. If the capability between the mental image and the external object suggests the truth, since the only proof I have of an external world consists of internal pictures then a true word of objects is impossible to establish. However, Hume recognizes that this sort of skepticism violates a certain level of common sense. Hume suggests complete skepticism is not useful since "nature is always too strong for principle" (Hume #), making this philosophical view unrealistic to human nature.
Moreover, Hume deduces that if we cannot understand why some parts of our bodies move free while others move instinctively then the power of the mind is limited thus we turn to experience for reason. We must understand why we can control our fingers and not our spleen in order to experience necessary connection. For example, Hume provides the occurrence of a “phantom limb” in order to show how our will is influence through experience without instructing us of a necessary connexion. In other words, in order to move our limbs our the power of our will should do just that but we are unaware of various unknown micro movements oblivious to our knowledge that must come into play in order to acquire the desire action. If the micro movements were to be felt as we “feel” the
Rene Descartes introduces his argument by questioning the certainty of everything based on the deceptive human senses, and unreliable memory which leads him to conclude that almost nothing is absolutely certain. Descartes argues that if there is a possibility that everything surrounding him is merely an illusion, then there must be a powerful being that is constantly deceiving him with a possibility of him himself being that being. He also believe that if he can convince himself of these ideas then he must be something and thus concludes that if he is capable to think then he exists even without a body or a shape. He further reflects on his existence as a man with body parts and shape who consumes food and walks the earth. As a result, he deduces
On the contrary to Descartes’ reflections, from the point of Dennett as physicalist, the only kind of substance is physical. In his paradigm, everything which exists is either physical or supervenes from the physical, which is a materialist view. However, this view presents even more complicated approach to defining the self, since it is not underlining the importance of soul, but instead allows only the material explanations to exist. From this point, as it was mentioned referring to body transplantation, neither the body alone nor the brain do not reflect the “self” of a human, since it generates paradoxes of responsibility and identity. However, the brain has stronger position, since it has more opportunities without body than body without brain: i.e., it can hear the music through direct influence at appropriate nerves.
