In the paper "Epiphenomenal Qualia," Frank Jackson presents the concept of Qualia and the knowledge argument in order to prove physicalism false. Jackson 's knowledge argument introduces a thought experiment about a neuroscientist called Mary. His thought experiment is designed to refute physicalism by showing that there is non-physical knowledge in the world. However, there are many flaws in Jackson 's thought experiment that lead to its ultimate failure in proving that physicalism is wrong, such as its appeal to a misleading intuition, the ambiguity of its premises, and the assumption that it is possible to gain all physical knowledge of color from a colorless room. Jackson explains that the goal of his paper is to refute physicalism by using an argument rather than relying merely on intuitions. He makes a declaration that he is what people call a "qualia freak." He describes qualia as the raw feel or quality of experiences that we have. There is something that the "hurtfulness of pains, the itchiness of itches, pangs of jealousy... tasting a lemon, smelling a rose, hearing a loud noise or seeing the sky" feels like (127). There 's a natural feeling or a sensation that all these conscious experiences bring for the person experiencing them. Jackson claims that qualia cannot be explained by any kind of physical information, since our knowledge of the structure of the brain, its physical states, and the function of those states is not enough to tell us what the smell
She argues the reader can conceive of feeling the pain from the pinch while being disembodied and, because conceivability equals possibility, it is possible to feel pain without a physical state. For disembodied pain to be possible, sensations like pain cannot be identical to physical states. Therefore, physicalism must be false. (113) Gertler posits that thought experiments like hers are useful only when the concepts they involve are made clear and unambiguous. Both the concepts of the physical and of pain, she asserts, are not subject to lack of clarity or comprehension. (114) Since we have a “sufficiently comprehensive” understanding of these two central concepts in the thought experiment, the conceivability test provides justification for what is possible. If what we can conceive can be possible, then conceiving of disembodied pain, having satisfactory understanding of what pain means, results in the possibility of disembodied pain.
We first see the example of the “Black and White Room” provided in the article “Epiphenomenal Qualia” written by philosopher Frank Jackson. The experiment is essentially used to exhibit the non-physical nature of mental states. Basically, Jackson creates Mary, who lives in a colorless room for her entire life. In other words, she has never seen color in her entire life, though she is not color blind so she is capable of doing so. She is given books and other studies (obviously in black and white) about how light and reflection work in order to create color. Mary reads the information provided and becomes an expert on the topic. Lets say Mary knows every possible bit of information there is to know about
As mentioned above, the Physicalist doctrine has come under serious threat by an argument for Property Dualism (and therefore against Physicalism). We have already seen this Property Dualism Argument (henceforth PDA) in its original formulation by J.J.C. Smart, but it will be helpful to look at a few of its reincarnations to fully grasp its scope. I will introduce two notable and familiar examples, namely Chalmers’ Zombie argument and Jackson’s Mary’s room argument, and then show, using Block’s terminology of reference, how they boil down to having the same generic form as Smart’s (CHECK WHETHER YOU’RE PLAGIARISING FROM BLOCK HERE). Formulating the generic PDA in Block’s terms exposes its central premises as well as its critical points.
The problem with this for physicalism is that fact Mary would realize how mistaken her knowledge of other's conceptions has been. Even though Mary would have known all of the neurological processes in a person's mind, she would not have known the person's actual experience involved in the process. There would also be facts she did not know about objects, but she would know all physical facts about them. For this reason it is not any experience the object may have, but a fact about the object itself.
The Knowledge Argument by Jackson is one of the main threats to Physicalism. Physicalism says that everything that is or could ever exist is ultimately physical in nature. The Knowledge Argument claims that there are truths about consciousness that cannot be deduced from the complete physical truth. Lewis’ response on the other hand, disagrees with the Knowledge Argument. In this paper I will address the Knowledge Argument and Lewis’ response to it.
In the black and white room, Mary learns everything that there is to know about the physical nature of the world. “She knows all the physical facts about us and our environment”. (IP, 291) When she leaves the black and white room, or receives a color television, she will learn something new. She will learn what it is like to experience colors. For example, Mary could know all the physical things to know about the color red, but until she actually sees it and experiences it, she won’t know what it feels like to see the color red. When she does experience the color of red, she will learn new information rather than just old information represented in a different way. This refutes the idea of physicalism because it argues against the view that
the most important arguments in the philosophy of mind. Physicalism is the metaphysical thesis that, basically, everything in this world-including cars, humans, animals, research papers, even our sensations-are ultimately physical. The knowledge argument attempts to refute this thesis by appealing to the following made-up scenario known as “Mary’s Room”:
Filled with sensorial imagery, John Keats’s use of the senses in “Ode to a Nightingale” leads to synesthetic description in order to convey what he is feeling and what he is imagining. This poem is based in a desire for escape and this is achieved through an imaginative bower in the speaker’s mind. The speaker is taken to this bower “on the viewless wings of Poesy” (Ode 928) whose song has put him into such a sublime state that his senses are heightened; due to these heightened sense, the speaker turns to synesthesia. Synesthesia, according to the Oxford English Dictionary, is “the use of metaphors in which terms relating to one kind of sense-impression are used to describe sense-impressions of other kinds” (OED). This form description is used to describe the speakers the sensations he is feeling and the images in his imagination. The imagination is where Keats’s bower is located which affects the definition of the bower. A bower, in the poetic sense, is supposed to be “an idealized abode, not realized in any actual dwelling” (OED) which is the reason the speaker flies there to escape, due to its idealized state. However, Keats’s ideas on the imagination affect the bower and ultimately lead to the speaker’s choice to leave the bower and return to reality. Through this journey, synesthesia is only seen in the instances of intense sensation in the speaker’s sublime state; meaning, when the speaker
Person descriptions. Philosopher Frank Jackson, an anti-physicalist, proposes the knowledge argument against physicalism, which goes as follows:
Synesthesia is a condition in which the stimulation of one sensory pathway leads to involuntary stimulation of another sensory pathway (Wikpedia 2015). Synesthesia can involve any of the senses such sight, hearing, taste, touch and smell. According to Palmeri, Blake and Marios (2006) article in Scientific American, synesthesia is an anomalous blending of the senses in which the stimulation of one sensory modality produces sensation in another modality. Synesthetes hear colors, feel sounds and taste different shapes. Drug induced hallucinations are different from synesthesia in the fact that synesthetic sensations are highly consistent where drug induced hallucinations are not (Palmieri, et al., 2006). The estimated prevalence of synesthesia

Consciousness, Thomas Nagel states, “is what makes the mind-body problem really intractable.” Here he refers particularly to phenomenal consciousness, which Block defines as “perceptual experiences,” and Nagel describes as “something that it is to be.’ This experiential element appears to present a challenge to the physicalist assertion that all mental processes are explicable in terms of physical brain states, biochemical reactions and the laws of physics. Frank Jackson presents this argument in his 1982 thesis Epiphenomenal Qualia. Whilst Jackson’s argument occupies a seminal position in philosophy of mind, whether he adds anything new to knowledge of the nature of conscious experience, is debateable. Thomas Nagel’s What is it like to
Synesthesia is a mysterious occurrence that varies amongst each individual who experiences synesthesia symptoms. In order to have a full comprehension of what synesthesia is, one must be aware that there are many different forms, stages, and theories that help explain synesthesia. According to Simner (2010), over 150 different manifestations of synesthesia have been discovered (e.g. Certain types of sound may trigger colors, or types of sound may trigger tastes). (p. 558). Although, there are many types of variations, there is no criteria or specific diagnostic that ultimately determines the difference between each characteristic of synesthesia. However, there are two forms of synesthesia that are most common. Some synesthetes in graphemecolor
At the beginning of Nervous Conditions, Tambu sees education as a pathway to financial success, based on the example set by Babamukuru. She describes her uncle 's offer to pay for Nhamo 's education as "oceanic," since it would "lift our branch of the family out of the squalor in which we were living." Babamukuru believes that education is the route to alleviate dependency. Meanwhile, his own wife, Maiguru, has a masters ' degree that she has never used. Tambu is desperate to be educated, as it will be her ticket out of poverty. When she arrives at the convent school, though, it becomes clear that her colonial education will continue to subjugate her because she is an African. To the white children, education is a right, and the Africans are taught to see it as a privilege. Looking back, Tambu recognizes that this system enforces a colonial power structure but at the time, it seemed a great opportunity and certainly does allow her to build a life outside of her family 's poverty.
Synesthesia is a perceptual condition where ‘‘stimulation of one sensory modality automatically triggers a perception in a second modality, in the absence of any direct stimulation to this second modality’’ (Sollberger, 2013). There are many different forms of Synesthesia that allow cognitive psychologists to make inferences about cognitive processing. It is important to note that Synesthesia is heterogeneous and idiosyncratic, that is to say no two synesthetes’ experiences are exactly the same. This condition has been documented to have at least fifty four different manifestations (Spector & Maurer, 2009) and due to the many theories that provide insight it is difficult to pinpoint the mechanisms that constitute the definition of Synesthesia. In this paper, the compilation of research is used to decode possibilities about the cognitive processes through analysis of neuroanatomical changes and the complex perceptive
