I shall present a case against materialist empiricism via Russell’s argument for the existence of a mind independent reality, followed by a critique of Russell’s stance by way of an updated version of Leibnizian Mathematical Rationalism, which will disprove Russell’s attempt at furnishing an objective mind independent reality through an empiricist epistemology. Russell’s argument for the existence of a mind independent reality is an attempt by Russell to justify the theory that material objects exist independently of mind. Russell argues in favor of a “direct realist empiricism”: The belief that knowledge is informed by the senses. His Direct realist argument is contrasted against Berkeley’s idealistic account of reality. Thus in opposition to Berkeley’s argument that only minds and that which they perceive exist – “esse est percipi” – Russell argues for empiricism with the criterion for the certainty that matter exists being the independent reality of physical objects. Russell approaches the question “Is there any knowledge in the world which is so certain that no man could doubt it” (Russell, Chapter 1), by employing the Cartesian method of radical doubt upon his present empirical experiences. In examining objects within the immediate environment, i.e., the table, Russell distinguishes between appearances and reality (what things appear to be and what they are) and determines that the color, hardness and shape of the table are subjective qualities of appearance only
Berkeley's attempt to popularize his pro-mind conception of the external world, Three Dialogues between Hylas and Philonous, serves to undermine Locke's distinctions between primary and secondary qualities of the external world. In his publication, Berkeley uses dialogue between Hylas and Philnous, which consists of a series of arguments, to determine the most sound theory. Ground rules of the debate consists of: whoever of the two's position avoids skepticism about knowledge of physical objects wins and that if one position can be shown to entail that we cannot know anything about physical objects, consequently that position should be dismissed as absurd (Kelly, 2013). Throughout the arguments, Berkeley weakens Locke's theory of Limited Representationalism by counteracting Locke's with the possibility that instead of “matter” that comprises physical objects in the external world, these objects are simply ideas. Drawing back on Berkeley's catchy motto, “to be is to be perceived”, he proposes three arguments that support his idealist view that the motto encapsulates. The three pieces of support also importantly shed skepticism upon Lockes primary and secondary distinctions involving “matter”. The three statements of support include: The argument that physical
What is the mind-body problem? The mind-body problem asks the question, are the mind and body separate substances of elements of the same substance? In this paper I wish to propose, and try to provide support for Descartes notion of the immaterial mind, by critically discussing the view of substance dualism, pertaining to the relationship between the mind and body. The two arguments of which I will provide in this paper to support this view are divisibility and disembodied existence. There are two fundamentally different substances in this universe, physical and mental properties, this paper will explore both of these substances (8).
Through the course of this paper, I began to wonder if it was even worth finishing. Thoughts rushed through my head on whether this Word document I was typing on even really existed. My reality as I presumed it to be may actually be thoughts in my head, and this philosophy assignment may have just been some weird way my own mind decided to entertain me. Perhaps yet, it may have been the work of a divine mind, taking helm of the way my thoughts flowed. These were all questions that came up as I read through George Berkeley 's, A Treatise Concerning the Principles of Human Knowledge. For in his manuscript, he addresses skepticism about the physical world, that is the ambiguity humans have in how a physical world outside of our minds is like. Berkeley has a simple solution to this. Through his interpretations of ideas, Berkeley comes to the conclusion that there should not be any skepticism surrounding the physical world because the physical world simply does not exist.
Philonous now begins to explain how materialism can lead to skepticism. Philonous must now explain that there is no reason to believe in mind independent reality. Philonous introduces the argument from pleasure and pain as well as the argument of perceptual relativity. First, he makes Hylas admit that we can only sense sensible things, and that sensible things are nothing but groups of sensible qualities. Hylas hesitates, but Philonous reassures him. Philonous gives a cherry as an example; a small, red, sweet cluster, which in actuality could be something other than this. Philonous now introduces the idea of pain and pleasure. Philonous explains that pain is mind dependant, meaning that pain cannot exist if nobody is feeling it. The same goes with pleasure. Philonous then explains that this does not only apply to pain and pleasure, but to any sensible quality. First, Philonous tries to relate heat with pain. He says that inanimate objects cannot feel pain or pleasure; Matter is inanimate; Matter cannot feel pain nor pleasure; heat is a form of pain; therefore matter is incapable of feeling heat; This means heat is mind
There are two main theories that make up the knowledge argument. The first is Physicalism, (or better known as materialism) which is the thesis that “All facts are dependent upon physical processes.”(Smart) The other main stance taken is property dualism. The thesis of property dualism states that there are “Non-physical properties of physical substances” (Calef) or that there are physical and mental properties. In this article, I will defend the stance of property dualism by acknowledging objections and replying to these objections to show why the argument for property dualism works.
G.E Moore, in his “Proof of an External World” attempts to offer the sceptics evidence for the existence of the external world. His evidence was simple, namely that of him having hands. In this essay, I will present Moore’s argument, and offer a critique, based on the Cartesian sceptic view.
I believe these two offer the best support to his argument because of sound reasoning, explained by natural science. Furthermore, I demonstrate how both Russell’s aforementioned arguments refute the existence of God, justify the improbability of God, and illustrate how God is unnecessary. i) Natural-Law Argument The first of two decisive arguments I will present by Russell is known as The Natural-Law
Abstract ideas pertaining to epistemology in philosophy are almost as old as the concept of philosophy itself. Dating back to thinkers such as Aristotle, carrying on throughout the medieval period and into modern philosophy, abstracts have always been grappled with. George Berkeley’s epistemology about abstract ideas has historically been one that has drawn the attention of many other scholars and philosophical thinkers. His thoughts on ideas, specifically his expansion of Locke’s general abstract ideas, are still argued to this very day. His critique of Locke’s view of abstract ideas and ideas in general, is successful in refuting his claims, and is validated in the Three Dialogues between Hylas and Philonous, and can be expanded upon in another one of Berkeley’s works, A Treatise Concerning the Principles of Human Knowledge.
The mind is perhaps the most fascinating part of the human body due to its complexity and ability to rationalize. In essence, the mind-body problem studies the relation of the mind to the body, and states that each human being seems to embody two unique and somewhat contradictory natures. Each human contains both a nature of matter and physicality, just like any other object that contains atoms in the universe. However, mankind also is constituted of something beyond materialism, which includes its ability to rationalize and be self-aware. This would imply that mankind is not simply another member of the world of matter because some of its most distinctive features cannot be accounted for in this manner. There are obvious differences between physical and mental properties. Physical properties are publically accessible, and have weight, texture, and are made of matter. Mental properties are not publically accessible, and have phenomenological texture and intentionality (Stewart, Blocker, Petrik, 2013). This is challenging to philosophers, because man cannot be categorized as a material or immaterial object, but rather a combination of both mind and body (Stewart, Blocker, Petrik, 2013). Man embodies mind-body dualism, meaning he is a blend of both mind and matter (Stewart, Blocker, Petrick, 2013). The mind-body problem creates conflict among philosophers, especially when analyzing physicalism in its defense. This paper outlines sound
During the 17th and 18th century two philosophers, Plato and Aristotle, arose carving for themselves a trench in the philosophical world. We can see the biggest distinction between the two in their theories of how we know things exist. The traditions of Plato and Aristotle have been dubbed rationalism and empiricism respectively. Under these traditions many well known philosophers have formed their own theories of God, existence and the material world. Through these individual theories I will show how each fits into the category of either Rationalist or Imperialist. The Plutonian philosophers to be
The notion of subjective idealism, within western philosophy, is credited to the 18th century philosopher George Berkeley. In his most notable work regarding this system of metaphysics, a Treatise Concerning Principles of Human Knowledge, Berkeley holds that nothing exists outside of the immaterial ideas within minds. “Esse est percipi” or “to be is to be perceived” (Berkeley,11). Berkley’s form of subjective idealism is able to avoid the problem of solipsism by his holding that the totality of perceived ideas reside in the mind of God. This monistic system of metaphysics runs contra to the earlier works of Locke and Descartes whose relative theories assumed a dualist stance concerning metaphysics. The philosophic relevance of subjective idealism is conveyed by Borges in “Tlön, Uqbar, Orbis Tertius,” when he cites David Hume who held “that
Empiricist philosophers such as John Locke believe that knowledge must come from experience. Others philosophers such as Descartes believe that knowledge is innate; this way of thinking is used by rationalist. In this paper I will discuss the difference between Descartes rationalism in his essays "The Meditations" and Locke's empiricism in his essays "An Essay Concerning Human Understanding". I will then lend my understanding as to what I believe as the ultimate source of knowledge.
The concept of mind and body interactions has been debated among many modern philosophers. Some believe that our minds and bodies are different things, thus existing separately, while others believe that they exist as a whole. In this paper, I will be introducing two rationalist philosophical views regarding this topic, one which is by Rene Descartes and the other by Gottfried Wilhelm Leibniz. Rationalists, in philosophical terms, are the ones who obtain their knowledge through reasoning rather than the human senses. Descartes and Leibniz both have similar perspectives, but Leibniz takes a slightly different approach to improve Descartes’ argument. This paper will first show Descartes’ original argument, an example that proves the argument to be invalid, and then lastly, a revised version of the argument with Leibniz’s help.
Berkeley offers both an epistemological and metaphysical argument against the idea of mind independent matter as an object of knowledge. Berkeley talks about the attributes of matter which are primary, quantitative, and geometric. Casual powers that change position and cause secondary qualities that apply to the senses and is what you see in your mind. He thinks the idea of matter is either contradictory or empty. When you subtract out the things that you get from your mind you are left with nothing. Sensation he says, is a thing in your head so it doesn’t belong to the object. If what we know about the world we know through perception and perception is in our minds then we must know nothing about the outside world. Our ideas of the attributes of matter are derived by abstraction from secondary qualities. If we have an idea of matter it comes from sense or by reason. Senses are ideas in our mind they don’t resemble what we perceive so it can’t be senses.
Empiricism, in contrast, argue that the rationalists' idea that all knowledge is present at birth, from such an innate source, is invalid . Instead, they argue that knowledge is attained through sensory experience. Empiricists also find problems with the rationalists' mathematical and logical model of knowledge. They argue that these claims, as well as their stand-point on absolute truths, do not provide us with any new, viable, information alone. The problem with this is that rationalism can only provide us with information that is already known. Unlike rationalists, empiricists rely on synthetic statements. A synthetic statement
