´╗┐Larry Pang 24.00 - Hare Essay #2 ? The Knowledge Argument Recitation Instructor: Jack Marley-Payne [3] Jackson aims to establish, by way of his Knowledge Argument, that the world has non-physical features. Reconstruct and assess this argument. ________________ The concept of physicalism and other beliefs concerning the connection between physical and mental features have been heavily disputed by philosophers for decades. Physicalism is the idea that everything in this world is defined by its physical features and that all conscious experiences can be described using the language of the natural sciences. Among many disputers, Frank Jackson argued this idea with his ?Knowledge Argument,? and believed that there are non-physical features of the world that cannot be understood unless consciously experienced (Jackson 1982). In this problem, I will investigate the question of whether or not Jackson?s argument defeats the idea of physicalism. I will first present Jackson?s Knowledge Argument and several counter-arguments and then show how two of these counter-arguments are not strong enough to disprove Jackson?s Knowledge Argument. However, I will argue that one counter-argument, the fact that representational states bridge the gap between the physical and non-physical, does cast doubt on Jackson?s Knowledge Argument and affirms the idea of physicalism. (Hare 2012) When debating the idea of physicalism, many skeptics argue that it is not only the physical features that define our world, but also possible non-physical features that are missing in a physicalist?s perception of the world. ...read more.


Churchland proceeds to discuss how musicians understand what every specific note sounds like individually and use this knowledge to put together chords using their imagination. When thought about from a ?new experience? point of view, if Mary knows how every part of the body will react to seeing color for the first time, then she can create this experience in her head much like how musicians put together chords from individual notes. The third and last counter-argument I will discuss is one proposed by Earl Conee called the ?acquaintance hypothesis.? This counter-argument is similar to the ?ability hypothesis? in the sense that both hypotheses believe that Mary did gain something after leaving the room (Conee 1994). However, unlike the ability hypothesis, the acquaintance hypothesis claims that Mary does not gain new facts or new abilities, but rather the ability to relate two epistemic understandings. This concept of being acquainted to something defends the idea of physicalism because it states that no factual knowledge is gained ? what is gained is the ability to recognize prior knowledge in a new mode of presentation. Conee states that Jackson?s assumption that Mary would gain some non-physical and factual knowledge does not hold because the only thing gained from going out of the room would be ?how to experience and acquaint oneself with the property.? Furthermore, some philosophers believe that Mary would know everything there is about the ...read more.


In comparison to Mary?s situation, after knowing everything about the color red it is impossible to say that she will learn something new from simply being presented the situation in a different fashion. Ultimately, one can think of this situation as comparing two states of mind. In the first state of mind, Mary knows everything about the color red but does not see it. In the second state of mind, Mary sees the color red and then knows everything about it. When comparing the two, Mary did not gain any physical or non-physical knowledge, but rather switches into a different state of mind without acquiring, reacquiring, or destroying any knowledge. Ultimately, the only thing that Mary acquires is knowledge of the relationship between the two states of mind and the ability to remember this relationship. In this paper, I have analysed the Knowledge Argument, which questions the concept of physicalism and states that knowledge is composed of physical and non-physical aspects. After providing several counter-arguments to the Knowledge Argument, I conclude that physicalism can be justified by viewing Mary?s situation from a relationship/acquaintance point of view. Ultimately, I do believe that the world has non-physical features, but that the non-physical is simply an avenue to understand the physical. When thought about from the viewpoint of two different states of mind, the concept of physicalism is successfully defended and that complete knowledge can be synonymous with a complete understanding of physical features and fluency in the language of natural sciences. ...read more.

  1. Kant's Philosophy

    has relation only to sensible data, and it is consequently useless in the quest of a knowledge of suprasensible realities. Kant's criticism on this point is directed against Descartes, who maintained that the soul, a spiritual substance, is the first object of knowledge.

  2. State and Assess Two Different Objections to the Cosmological Argument.

    is that we do not know everything must have a sufficient reason then it becomes true that everything must not have a sufficient reason. Even if it is assumed that at the present time the principle of sufficient reason is only known through inference it does not hold that it is not a priori truth.

  1. State and assess two different objections to the cosmological argument

    Now I will argue that it is wrong to state that the world as a whole needs a cause because it is possible that there are an infinite series of causes and no ultimate cause to the world. It is perfectly possible to conceive that the series of cause and effect in the world has no beginning and no end.

  2. What, if anything, does the Cosmological argument prove?

    to move back in a temporal sequence but seek to establish dependence, the dependence of the world on God now. Aquinas did not think it possible to prove that the universe had a beginning in time, this was simply revealed doctrine.

  1. Can physicalism account for qualia?

For the purpose of this paper, we may consider an attack on describability an attack on physicalism in general. The basic expression of physicalism is that of mind-brain identity, which suggests that a mental event is identical with a brain state.

    This is because human beings have naturally aggressive impulses - significantly, sex and violence - that would destroy society if not kept in check by civilizing mechanisms that force them to be expressed in more mediated and controlled forms (Freud 1929:10).

  1. Plato's and Aristotle's Views on Knowledge

    For this reason, I do not fall in these epistemological concepts afterwards. Moreover, a syllogism also cannot help one to acquire human knowledge. To Aristotle, these universal ideas are self-evident. The mind, having received appropriate sensory input, immediately sees that they are true.

  2. Is there an explanatory gap such that even perfect knowledge of the physical facts ...

    Even if it were possible, to have knowledge of everything physical in the world around us, and know everything about the human brain, thus has perfect knowledge of the physical, it seems that there is something about minds, or the mental, that we cannot explain.
