Objection to Descartes’ View on Senses

In René Descartes’ Meditations on First Philosophy he comes to the conclusion in his sixth meditation “On the Existence of Material Objects and the Real Distinction of Mind and Body” that our senses and their operations ought to be mistrusted, and that our own mind - our intellect - is more reliable than any perceived senses. I will investigate the validity of Descartes’ sixth meditation with respect to modern scientific views, particularly those of neuroscience which study the way the physical brain and nervous system is related to perceptions which a mind can have. I assert that the mind is not greater than the senses. This assumes that the senses are working properly, and that the mind is sound and not belonging to that of a madman (137). I also will go back to his previous meditations, and argue that Descartes cannot deduce our existence from the cogito ergo sum argument. Taking into account a scientific standpoint of the senses, it is not fair to claim “I think, therefore I am” (139) if one looks at intellect and consciousness as a result of scientific processes. Rather, all he can say is “I have thoughts.” One of the most concerning assertions Descartes makes is that the intellect is more reliable than the senses. He claims that this holds true because the senses have on occasion deceived him, and it is therefore “prudent for [him] to never completely trust those who have cheated [him] even once.” The senses have deceived him numerous times and have therefore shaken his faith in them (155) - towers which are square have looked cylindrical from a distance, large statues are smaller when seen from a different angle (155), and the sun looks small from the earth despite it’s immensity. But how is it possible that the intellect can have any certainty which it did not receive first from sensing things through experience?

Do We Really Know Anything?

...TOPIC 1: Do you really know anything? With reference to Descartes’ first meditation justify your answer in full and respond to possible objections. A belief is any opinion or any view whether you are committed to the view or not. Thus, if you know something, you are entitled to believe in it. The subjective nature of knowledge partly is based on the idea that beliefs are things that individuals have and those beliefs are either justified or not justified (Pardi, 2011). However, Descartes notices that over the course of his life, he has from time to time accepted false beliefs and the falsity of these beliefs have influenced other beliefs. Thus, Descartes aim in his first meditation is to find out if what we know is truly correct (Blackburn, 1999:15). Once we have figured out what beliefs are beyond any possible doubt, it is suggested that we can use reason to deduce the rest of what is knowable (Pardi, 2011). There are three conditions when one can say they know something is true (Pardi, 2011). Firstly, you believe in something, secondly, it is in fact true and lastly you are justified in believing a statement is true. Of course it is possible that there are no complete unshakeable truths, it is also possible that we might discover that our prejudices cannot be detached or that the beliefs we think are our grounds for all our other beliefs are not really ultimate at all. For this reason, it is why rationalist say that knowledge comes from within, the only beliefs we can...

Descartes Conceivability Argument

...and Possibility Without God: On Descartes Conceivability Argument In the sixth meditation of his Meditations on First Philosophy Descartes advances an argument for establishing a form of dualism. The argument, dubbed the ‘conceivability argument’, attempts to establish a ‘real distinction’ between the mind and the body by linking the conceivability of such a distinction with the possibility of said distinction. For Descartes, two things are ‘really distinct’ when they can exist separately. In this paper I will first outline Descartes argument, then question the place of God in the argument. I will next propose an argument for conceivability entailing possibility, consider an objection to the argument, and ultimately conclude that the ‘conceivability argument’ for the real distinction between the mind and body is viable without the necessity of God to providing a link between conceivability and possibility. Descartes begins his argument by stating ‘everything which I clearly and distinctly understand is capable of being created by God so as to correspond exactly with my understanding of it’ (54). This seems to be the critical premise of his argument, and it functions in several ways in his argument. First, it seems to establish a connection between what is conceivable and what is possible. Descartes seems to believe that if he can conceive of something, then God can make it such that what he conceives can be the case in reality. So for Descartes, the connection between conceivability...

Aristotle and Descartes

...Two Views of Soul: Aristotle and Descartes* THEODORE TRACY, SJ. What first attracted my interest to a possible comparison was the realization that, unlike Plato, both Aristotle and Descartes shared the view that, first, there is but a single soul and, second, that this soul operates principally through a single specific bodily organ. Given his own understanding, I believe Descartes could agree totally with Aristotle's statement that the soul's "essential nature cannot be * This paper was originally presented at the University of South Carolina in April 1981' as a contribution to a symposium on "Soul and Mind in Ancient Philosophy," organized by Professor Rosamond Kent Sprague. 248 Illinois Classical Studies, XI corporeal; yet it is also clear that soul is present in a particular bodily part, and this one of the parts having control over the rest":' dfiXou 6ri ovx oihv r' tivai adua rffv ovtriau ocvrfiq, aW 5fi(t)c, Sri 7' iv tlvl tov (TUifiaToq inrapxii^ nopiw (t>avtpbv, kcu iv tovtw tivi twv ixovruiv bvvafiiv eV roJq nopioic,. {Parva Naturalia 467b 13- 16) For Aristotle, as we know, that particular controlling organ is the heart.

Berkeley

...Berkeley: to exist is to perceive or to be perceived 'To exist is either to perceive or to be perceived.' - How would you explain Bishop Berkeley's idealism to someone who knew nothing about philosophy? This is a good essay. Many students are very puzzled by Berkeley's claim that his theory is intended as a 'defence against scepticism'. I don't know what a 'real' tree is, because I have never met one, and never will. All I know is my perception of this tree and other trees like it. - This seems an open invitation to the most extreme scepticism which denies that the objects of our perception exist. Berkeley's answer is that there is no 'real' tree, in the sense of some object or entity that exists apart from perception. All there is, is the possibility of my perceiving the tree, of enjoying my tree-perception, vouchsafed by God's unwavering attention to all the objects of his creation, which exist as nothing more than perceptions in God's mind. This response differs from another possible anti-sceptical response which avoids the God-hypothesis altogether. Why not say that the 'possibility of my perceiving the tree' is just that and no more? There is a hypothetical statement - or list of hypothetical statements - whose truth is equivalent to the 'existence of the tree'. You know what a 'statement' is, and what 'truth' means. You know what it is for a statement to be hypothetical ('if A then B'). Why not stick with that? The clear advantage of this theory - also...

Ontological Argument

...i) Examine the ontological argument as an a priori proof for the existence of God. (18) Ontology is the branch of philosophy that explores the whole concept of existence. Sometimes scientist have to assume that something exists in reality in the physical world even if they have never come across an example of it, because a combination of factors indicate that there must be X, even if we have not found it yet, in order to explain other things. The ontological argument for the existence of God is an a priori argument, working from first principles and a definition in an attempt to demonstrate the existence of God. It is also a deductive argument, using logic rather than depending on the evidence of sense experience. In this way, then the ontological argument is different from other attempts to argue for the existence of God. The ontological argument argues that almost everything, which exists, does so in a contingent way; it depends upon other factors. We as individuals are contingent beings; everything else apart from God exists contingently. God, however, it is argued by religious believers, is necessary rather than contingent, there was no time when God didn’t exist. There is nothing that could happen which would cause God to cease to exist. The ontological argument begins with assumptions about God, without any empirical evidence such as the characteristics of God: Omnipotent, omniscient and omnipotent. This is what makes the argument an a priori argument, as most of the...

Substance Dualism vs. Materialism

...is made up of two kinds of substances: physical matter and above all else, an immaterial force known as the mind, or soul. Materialism refutes dualism, asserting that man and matter are inseparable, and that there is no mysterious, supernatural force directing our actions. Both viewpoints were derived in an attempt to place philosophy on firmer, more scientific ground. The arguments of Descartes and Hobbes for substance dualism and materialism, respectively, are representative of this debate. Although materialism and dualism have their own internal problems and flaws, I will argue that many of the objections that have been leveled against materialism can be met and that, on the whole, materialism is a much more plausible theory than dualism. The Greek philosopher Socrates believed that nothing could be certain without divine knowledge, which no man possesses. However, René Descartes, a 16th century French philosopher believed that some things could be determined to be certain as long as they were deduced through the proper methods. This method, known as the method of doubt, led Descartes to the foundational beliefs that became the basis for Substance Dualism. Simply put, Substance Dualism is the belief that there are two types of substances: the material body, and the immaterial mind. The existence of the mind, and therefore of thought, cannot be doubted based on the premise of “I think, therefore I am”. The body however can be doubted because belief of its existence relies...

The Conceivability and Divisibility Arguments

...Meditation VI: The Conceivability and Divisibility Arguments The Argument Introduced The Conceivability Argument occurs in Meditation VI. It is Descartes’ most celebrated argument. It was criticised in its day and has been ever since. The argument purports to establish that minds are non-physical substances and hence that a mind is not identical to any bit of the body, such as the brain. A person is a special unity of two substances: physical substance (the body) and mental substance (the mind). Only humans are such special unities. Animals have bodies but lack minds and angels have minds but lack bodies. Here’s the passage: First, I know that everything which I clearly and distinctly understand is capable of being created by God so as to correspond exactly with my understanding of it. Hence the fact that I can clearly and distinctly understand one thing apart from another is enough to make me certain that the two things are distinct, since they are capable of being separated, at least by God. The question of what kind of power is required to bring about such a separation does not affect the judgment that they are distinct. Thus, simply by knowing that I exist and seeing at the same time that absolutely nothing belongs to my nature or essence except that I am a thinking thing, I can infer correctly that my essence consists solely in the fact that I am a thinking thing. It is true that I may have (or, to anticipate, that I certainly have) a body that is very...

Cartesian Dualism In Simon Blackburn's Think

...Simon Blackburn’s “Think” Are experiences through senses and experiences in the mind independent? Simon Blackburn attempts to answer this question by first explaining the “Zombie and Mutant Possibilities.”(pg. 52) The Zombie Possibility proposes that people may look and behave like ones-self but are not conscious. The Mutant Possibility proposes that there are people who look and behave like oneself and are conscious, but do not interpret feelings or senses the same way that you do. The idea being proposed is that if the mind can live on without the body then the body can live on without a mind. The body would still respond to things the way one with a conscious mind would but it would not be aware of its own existence. This idea is called Cartesian...

This is an analysis of the "empiricist" view: both Hume and Locke are empiricists as they argue that all knowledge depends on experience.

Notes Towards a Philosophy of Sleep

...The column you’re reading is at least in part the result of an accident – a happy one, I hasten to add. A few weeks ago, I was sitting on a panel with the philosopher Christopher Hamilton, discussing the question of whether a world without pain is an appropriate goal for mankind or whether pain serves some additional positive purpose other than the obvious biological one of directing us away from things that might harm us (a topic, perhaps, for a future column). Meeting Christopher after a long interval reminded me of his excellent book Living Philosophy: Reflections on Life, Meaning and Morality (2001). The volume includes a fascinating essay entitled ‘The Need to Sleep’, where he notes that philosophers have not paid sufficient attention to this extraordinary phenomenon. Well, a decade on, this is the beginning of a response to Christopher’s wake-up call. For sleep is rather extraordinary. If I told you that I had a neurological disease which meant that for eight or more hours a day I lost control of my faculties, bade farewell to the outside world, and was subject to complex hallucinations and delusions – such as being chased by a grizzly bear at Stockport Railway Station – you would think I was in a pretty bad way. If I also claimed that the condition was infectious, you would wish me luck in coping with such a terrible disease, and bid me a hasty farewell. Of course, sleep is not a disease at all, but the condition of daily (nightly) life for the vast majority of us...

Worldview

...(Hummel, p. 106). Contrary to popular belief, the cause for the diversion between Christianity and science originated not with the Church but with the university professors who were threatened by Galileo’s revolutionary ideas. These professors were steeped in the Greek scientific method, which included observation to a small extent, but mostly explained the workings of nature through rational deduction from first principles, or assumptions, an entire view of the universe had been built up. Consequently, the professors embraced such misconceptions as the sun having no imperfections, the moon being a perfectly smooth sphere that shone with its own light, and the earth alone having a moon since the earth was at the center of the universe. Galileo’s recently invented telescope quickly demonstrated the incorrectness of such assumptions (Hummel, pp. 91-94). Not willing to be thwarted by Galileo, the professors decided to make the controversy religious rather than academic (Hummel, p. 92). They argued that the heliocentric (sun-centered) view contradicted scripture (e.g., Psalm 104:22 says, “The sun rises.” Therefore, the...
