Thomas Reid argument (or From Epistemic Justification)

Argument:


(1) we trust perceptions that work for us in navigating the world

(2) we judge by criteria Regular. Consistent Shared

experiences that fit this criteria we judge to be valid.

(3) Religious Experience "RE" fits this criteria

(4 )enables navigation

(5) :. we are warranted to trust RE as indicative


*We assume reality by means of a Jugement

*we make such jugements based upon criteria

*Because RE fits the same criteria we are justfied in making the same assumption; ie that these experinces are idicative of a reality.

The criteria: If our experiences are:

*Regular
*consistant
*inter=subjective
*navigational

Then we assume our eperience3s reflect reality.

VIII. The Thomas Reid Argument.

A. How do we Know the external world exists?

Philosophers have often expressed skepticism about the external world, the existence of other minds, and even one's own existence. Rene Descartes went so far as to build an elaborate system of rationalism to demonstrate the existence of the external world, beginning with his famous cogito, "I think, therefore, I am." Of course, he didn't really doubt his own existence. The point was to show the method of rationalism at work. Nevertheless, this basic point, that of epistemology (how we know what we know) has always plagued philosophy. It seems no one has ever really given an adequate account. But the important point here is not so much what philosophers have said but what most people do. The way we approach life on a daily basis the assumptions we make about the external world. Skeptics are fond of saying that it is irrational to believe things without proof. I would argue that they, an all of us, believe the most crucial and most basic things without any proof whosoever, and we live based upon those assumptions which are gleaned with no proof of their veracity at all!

B. Consider Thomas Reid's Common Sense Philosophy of Foundatinalism and Fallibalism.

The point of departure here is Reid's discussion of Hume and the problem of justification of the external world. This is discussed in lecture notes of a contemporary philosopher, G.J. Mattey, in his lecture notes.

1) Skepticism about the External World

Thomas Reid, Theory of Knowledge lecture notes.G.J. Mattey
Philosophy, UC Davis

"Consider the question whether we are justified in believing that a physical world exists. As David Hume pointed out, the skepticism generated by philosophical arguments is contrary to our natural inclination to believe that there are physical objects." "[T]he skeptic . . . must assent to the principle concerning the existence of body, tho' he cannot pretend by any arguments of philosophy to maintain its veracity. Nature has not left this to his choice, and has doubtless esteem'd it an affair of too great importance to be trusted to our uncertain reasonings and speculations. We may well ask, What causes induce us to believe in the existence of body?, but 'tis in vain to ask, Whether there be body or not? That is a point, which we must take for granted in all our reasoning." (A Treatise of Human Nature, Book I, Part IV, Section II) "Nonetheless, after considering the causes of our belief in the existence of body and finding them inadequate for the justification of that belief, Hume admitted to be drawn away form his orignal assumption that bodies exist. 'To be ingenuous, I feel myself at present . . . more inclin'd to repose no faith at all in my senses, or rather imagination, than to place in it such an implicit confidence,' because ''tis impossible upon any system to defend either our understanding or senses." His solution to these doubts was "carelessness and in-attention,' which divert the mind from skeptical arguments."

2) Reid's Defense of Commonsense Beliefs.

Mattey again:

"Thomas Reid, who was a later contemporary of Hume's, claimed that our beliefs in the external world are justified.'I shall take it for granted that the evidence of sense, when the proper circumstances concur, is good evidence, and a just ground of belief' (Essay on the Intellectual Powers of Man, Essay IV, Chapter XX). This evidence is different from that of reasoning from premises to a conclusion, however."

"That the evidence of sense is of a different kind, needs little proof. No man seeks a reason for believing what he sees or feels; and, if he did, it would be difficult to find one. But, though he can give no reason for believing his senses, his belief remains as firm as if it were grounded on demonstration. Many eminent philosophers, thinking it unreasonable to believe when the could not shew a reason, have laboured to furnish us with reasons for believing our senses; but their reasons are very insufficient, and will not bear examination. Other philosophers have shewn very clearly the fallacy of these reasons, and have, as they imagine, discovered invincible reasons agains this belief; but they have never been able either to shake it themselves or to convince others. The statesman continues to plod, the soldier to fight, and the merchant to export and ijmport, without being in the least moved by the demonstations that have been offered of the non-existence of those things about which they are so seriously employed. And a man may as soon by reasoning, pull the moon out of her orbit, as destroy the belief of the objects of sense." (Essay on the Intellectual Powers of Man, Essay IV, Chapter XX)

"Here Reid shows himself to have foundationalist tendencies, in the sense that our beliefs about physical objects are not justified by appeal to other beliefs. On the other hand, all he has established at this point is what Hume had already observed, that beliefs about physical objects are very hard to shake off. Hume himself admitted only to lose his faith in the senses when he was deeply immersed in skeptical reflections. But why should Reid think these deeply-held beliefs are based on "good evidence" or "a just ground?" One particularly telling observation is that a philosopher's "knowledge of what really exists, or did exist, comes by another channel [than reason], which is open to those who cannot reason. He is led to it in the dark, and knows not how he came by it" (Essay on the Intellectual Powers of Man, Essay IV, Chapter XX). Philosophers "cannot account for" this knowledge and must humbly accept it s a gift of heaven."

"If there is no philosophical account of justification of beliefs about the physical world, how could Reid claim that they are justified at all? The answer is the way in which they support common sense."

"Such original and natural judgments [based on sense-experience] are, therefore, a part of that furniture which Nature hath given to the human understanding. They are the inspiration of the Almighty, no less than our notions or simple apprehensions. They serve to direct us in the common affairs of life, where our reasoning faculty would leave us in the dark. They are part of our constitution; and all the discoveries of our reason are grounded upon them. They make up what is called the common sense of mankind; and, what is manifestly contrary to any of those first principles, is what we call absurd. (An Inquiry into the Human Mind, Chapter VII, Section 4)"

"One might say that judgments from sense-experience they are justified insofar as they justify other beliefs we have, or perhaps because they are the output of a perceptual system designed by God to convey the truth. (Of course, if the latter is what gives these beliefs their justification, the claim that we are designed in this way needs to be justified as well.)"

C. In other words, We accept the existence of the external world as a matter of course merely because we perceive it.

1) Acceptance of Perceptions about the world.

But it is not merely because we percieve it that we accept it. It is because we perceive it in a particular sort of way. Because we perceive it in a regular and consistent way. This has been stated above by Reid. The common man goes on with his lot never giving a second thought to the fact that he can no more prove the veracity of the things around him than he can the existence of God or anything else in philosophy. Yet we accept it, as does the skeptic demanding his data, while we live out our lives making these assumptions all the time.

2) Consistency and Regularity.

If every time we woke up in the morning it was in a different house, with a different family, but one which make the assumption that we did nevertheless belong there and always had, and if the route to work changed every morning, if we never went to the same job twice, if our names and our looks were always different each day, we might think less of direct observation. But because these things are always the same from moment to moment and they never differ, we learn to trust them and we trust them implicitly as a matter of course. We do not try to prove to our selves each day when we get up "I am the same person today that I was yesterday," precisely because we learn very early that we always are the same person. We observe early on that we cannot penetrate physical objects without leaving holes and so we do not try to walk though walls; we know that doesn't work because it never works.

Hume observed that when we see two billiard balls we do not really see the cause of one making the other one move. What we really observe is one stopping and the other one starting. But, in practical terms, we do not observe the causality of a car running over the pedestrian as causing the pedestrian to fly across the road, but we know from experience that these two factors usually go hand in hand and so we don't play in the street.

a) Empirical proof?

In making this argument on boards many skeptics have argued "I see that the world is real with my own eyes." That's the point, why trust your eyes? You cannot prove they are seeing things properly. Everything could be an illusion everything we observe could be wrong. We cannot prove the existence of the external world, we assume it because it is always there. Some try to claim this direct observation as empirical proof. But they are confusing the notion of scientific empiricism with epistemological empiricism. Before we make the assumption that scientific data is valid we first make the epistemological assumption that perception is valid. Otherwise there would be no point in assuming the data. So epistemological empiricism is prior to scientific methods. In fact we have to simply make this assumption a priori with no proof and no way around the problem in order to able to make the assumptions necessary to accept scientific data. WE do usually make these assumptions, but they are assumptions none the less.

b) Science cannot prove reality.

Still others try to content that empirical scientific evidence proves the reality of the external world. But of course if the world were an illusion than any scientific evidence we gather would be part of the illusion as well. So there is no other way to demonstrate the truth of the external world, the existence of other minds, or the reality of our own existence except through the consistency and regularity of our sense data.

D. Religious belief Justified prima facie based upon Religious Experience

1) Prima Facie Justification.

Mattey again:

"Far from concluding that our senses are "fallacious," Reid placed them on the same footing as memory and reason, though they are "undervalued" by philosophers because "the informations of sense are common to the philosopher and to the most illiterate. . . . Nature likewise forces our belief in those informations, and all the attempts of philosophy to weaken it are fruitless and in vain."

"Reid pointed out that when we fall into error regarding the objects of sense, we correct our errors "by more accurate attention to the informations we may receive by our senses themselves." So the "original and natural judgments" that are made on the basis of our constitution lose their original justification in the presence of additional information. Contemporary philosophers call this kind of justification "prima facie," a term from law which describes an initially plausible case that could prove to be entirely implausible given further evidence. A belief of common sense, then, is justified "on the face of it."

"According to the doctrine of prima facie justification, one is justified in accepting that things are the way they appear, when

* it does appear to one that they are that way, and
* there is no reason to think that something has gone wrong.
[Ibid]

"But if there is such a reason, one's justification is "defeated." Thus prima facie justification is "defeasible."

"For Reid, our beliefs about physical objects are justified by sense-experience, which he took to be a product of the interaction between the senses and physical objects. Twentieth-century philosophers have been somewhat more cautious, however, and have followed more closely the account of perceptual knowledge given by Reid's predecessors such as Descartes, Locke and Hume: that what justifies our beliefs about physical objects is a mental state such as:

* looking like something is red
* a sensation of red
* seeing red-ly"

"For example, what justifies a person in believing that he sees something red is that it looks to him as though there is something red. The mental state of that person is one in which there is an appearance of red, and just being in this mental state is enough to give prima facie justification to the belief that he really sees something red. On the other hand, what confers justification might be a belief about how things appear."

2) No contradiction to prmia facie case.

But I will argue that such further evidence is not forth coming. This is because no amount of evidence can ever prove the basis of the external world. If the world is an illusion everything we have access to as evidence of its veracity is always going to be inside the illusion. This is because we can never break out of the epistemologist dilemma, we cannot step outside of our own perceptions to check them. The consistency of experience itself is no guarantee of their truth content, but we live as though it is because we cannot live otherwise.

3) Prima Facie justification for Religious experience

Religious experience is "properly basic," it is built upon experiences that are regular and consistent in the same way that our experiences of the external world are, and thus they are justified prima facie. observe the two criteria:

E. Objection: Is The PF case is overturned with further examination?

1) Is religious experience consistent and regular?

Skeptics have argued that religious experience is not regular or consistent because such experiences are all different. Not only do you have so many different religions, but even from mystic to mystic things differ.

a) Consistency and over time.

Over the years as one develops a disciplined life of prayer, one does encounter growing diversity and newness, but a certain sense of the familiar as well. Experiences become regular and consistent in that the presence of God is usually found in prayer, the sense of the presence is always the of the same quality (although varying intensity) and the sense of God can become familiar enough that it is always recognized as the same.

b) Times millions of believers.

This sense of the familar is communicable and can be recognized form one believer to another. The mystical and devotional literature presents a kind of ordered sameness. One can read accounts as different form one experiencer to another as those between St. Augustine and A.W. Tozer and still find passages that seem to be talking about the same things. This is amplified times millions of believers in the history of the church who have experienced the same things. Even though there is diversification and difference there is still a sameness. This is not even confined to mystics. The same can be said of conversion accounts, that the same aspects keep pooping up. Once can recognize the work of God from one person to another, form one time to the next, from one culture to all cultures.

c) across traditions.

But what about the vast aray of different religions? These differences are due to cultural constructs. One experiences God beyond words, and when one tries to speak of such experiences one must encode them in a symbolic universe, that is to say, in culture. These differences in symbolic universes over time have spelled out the differences in the many religions. But there is a cretin unity even between all the differences in religion. The data presented above on long term effects represents typologies which can be used to compare "peak experience" with that of other phenomena. The Peak experiencers can be grouped together into a collection of those who have experiences X. They are not isolated assortments of differing phenomena. These studies do represent differing cultures and times. Thus, religious experience has a consistency to it even between cultures.
