C. S. Lewis on the "progress" of modern thought

A redated post.

This is a passage from C. S. Lewis's The Empty Universe, which was a introduction Lewis wrote to a book entitled A New Diagram of Heaven and Earth by a man named Harding. It parallels some of the comments I have been putting up on DI2 about the "siphoning off" argument is Swinburne and Feser.

The process whereby man has come to know the universe is from one point of view extremely complicated; from another it is alarmingly simple. We can observe a single one-way progression. At the outset the universe appears packed with will, intelligence, life, and positive qualities; every tree is a nymph and every planet a god. Man himself is akin to the gods. The advance gradually empties this rich and genial universe, first of its gods, then of its colours, smells, sounds and tastes, finally of solidity itself as solidity was originally imagined. As these items are taken from the world, they are transferred to the subjective side of the account: classified as out sensations, thoughts, images or emotions. The Subject becomes gorged, inflated, at the expense of the Object. But the matter does not rest there. The same method which has emptied the world now proceeds to empty ourselves. The masters of the method soon announce that we were just mistaken (and mistaken in much the same way) when we attributed “souls” or ‘selves” or “minds’ to human organisms, as when we attributed Dryads to the trees. Animism, apparently, begins at home. We, who have personified all other things, turn out to be ourselves mere personifications. Man is indeed akin to the gods, that is, he is no less phantasmal than they. Just as the Dryad is a “ghost,” an abbreviated symbol for certain verifiable facts about his behaviour: a symbol mistaken for a thing. And just as we have been broken of our bad habit of personifying trees, so we must now be broken of our habit of personifying men; a reform already effected in the political field. There never was a Subjective account into which we could transfer the items which the Subject had lost. There is no “consciousness” to contain, as images or private experiences, all the lost gods, colours, and concepts. Consciousness is “not the sort of noun that can be used that way.”

The Kalam Cosmological Argument from Philoponus to Prokop

To preface this, Bob Prokop, a sometime commentator here, is an friend of mine from undergraduate days at ASU, whom I met in a History of the Middle Ages class in 1973. I remember Bob explaining a theistic argument to me in a classroom at ASU in 1975, some four years before William Lane Craig published his first work on the Kalam Cosmological argument. I later discovered that the argument had been used by the Scholastics during the Medieval period. Little did I know that Bob's argument would become the most discussed theistic argument of the last 25 years. I got back in touch with Bob after a long time out of touch, and he wanted to see what I thought of this argument he invented when he was an undergrad.

The reason I wanted to e-mail you is that I would like you to try and find a flaw in what I believe is an iron-clad proof that the universe must have been created, and cannot possibly have always existed.






As prelude to my argument, I have to confess that for myself, my very existence has always been evidence enough for a Creator (read: God). My mind simply can not and will not accept the idea that the universe "just is". So for me, the existence of God is Case Closed, and I generally find debates on the subject to be rather pointless. BUT, I am fully aware that existence itself is not considered to be sufficient proof of a Creator by the hard-core atheist, who generally respond with two objections which they think are fatal flaws in the "Argument for Existence".


First Objection: "Then where did God come from?" This one is simple. The question is semantically null - without meaning. The Creator is by definition the Creator, and not a creation. To ask who created the creator is to string words together to no purpose.


Second Objection: Now this one is worth refuting. The argument runs thus. Existence does not require a Creator, because the universe has always been here from eternity, and therefore "just is".


I respond to that proposition with a simple thought experiment. Call this a sub-set of the "Argument from Existence" - maybe a good name for it would be the "Argument from there being a Now". Thus:


1. Imagine a time a billion years in the future. You know that in a billion years from now, that time will be the present. The same works for any finite number you can name, no matter how large. At some point, we'll get there, and some future person will be able to experience that point in time as "Now".


2. Now, imagine a point in time an infinite number of years in the future. In this case, no matter how long you wait, we'll NEVER arrive at that point. It will never be the present, but always and forever an infinite time in the future, and no one will ever experience that time as "Now".


3. Now let's go in the other direction. Imagine 14 billion years ago (the current rough estimate of the age of the universe, give or take a billion years or so). Starting from that point, we eventually get to where (when?) we are today - the present time.


4. Finally, imagine a point in time an infinite number of years in the past. Just as in step 2, we would never, ever get to today. Our present existence becomes an impossibility. It would always be an infinite time in the future, and never arrived at.


THEREFORE: The universe (Creation) requires a beginning, before which there was nothing. It cannot have always been here, or we would not be here "Now". Creation Ex Nihilo


So my challenge to you - where is the flaw in this argument? I cannot find one. Also, as an aside, has anyone else ever used this argument. I don't recall ever seeing it anywhere. (Here's where you get your chance to show how uneducated I am, and point out that it dates back to Augustine, or something like that!)


Bob

I gave a couple of replies to Bob: I remember you came up with an argument for theism which had not been discussed much by the early 70s, but a Christian philosopher named William Lane Craig developed it, and his book, the Kalam Cosmological Argument, was his first major publication, tracing it back to Islamic thinkers of the early Middle Ages.



Here is some Craig stuff on the argument:

http://www.leaderu.com/offices/billcraig/menus/existence.html

And this is the response of who I think is his best critic, Wes Morriston.

There is also the move that says that the beginning of the universe just doesn't need a cause, that a cause is required only if there is a time prior to the beginning.

Whenever you see the phrase, "Kalam Cosmological Argument," that's the argument this is talking about.

Thomas Aquinas didn't use this argument.  I think Joe Sheffer (another friend of ours from undergrad days, and a big-time Aquinas aficianado who, tragically, passed away in 1989) criticized the argument also, but my photographic memory fails me as to just how that discussion went. Here is a discussion on Aquinas's understanding of the infinite, which provides the reason why he rejected the argument, and made the claim that the universe had a temporal beginning (and therefore a temporal first cause), an article of faith known through revelation, rather than something established by natural reason alone.

When Bob asked me my own view of the argument, I replied (well, mostly):

Well, you have to realize that, thanks to William Lane Craig, this argument has gone from being an obscure argument dating back to golden age of Islam, and used by some scholastics (but NOT Aquinas), to being the most discussed argument for the existence of God in the past 30 years. A large body of papers have been written about it, I've only read a fraction of them. The very latest is a paper by William Lane Craig and James Sinclair in Craig and Moreland, ed. The Blackwell Companion to Natural Theology.

The argument basically says that, when it comes to counting anything, infinity can't be real. More precisely, a completed infinite set of past moments is impossible. Yet there is an infinite set of integers. All these numbers do exist, yet there is an infinite number of them. There is a set, but I suppose there is the question of whether it can be traversed. Hence there had to be a beginning, because if there wasn't, there would be no now. Mathematicians make a distinction between an actual infinite and a potential infinite, and say that an actual infinite is impossible.

One question might be to ask you how many moments are there in our heavenly future? If there can be an infinite number of future moments in which we praise God, (we've no less days to sing God's praise than when we first begun), then can't there have always been an infinite number of past moments prior to this one?

I haven't worked through what are considered to be the strongest objections to the argument against an infinite number of past moments, and I haven't worked my way through the question of why Aquinas rejected the argument, concluding that the claim that the universe had a temporal beginning was an article of faith, rather than provably false, which is what your argument shows if it works. (If it had made it into the Five Ways, it would have been extensively discussed by philosophers).

An interesting sidelight to this whole argument has to do with Big Bang cosmology. Is cosmology trending in the direction of accepting a beginning of the universe, as attempts to get rid of an absolute beginning at the Big Bang keep going down the tubes. Is science showing that there was a beginning?

The argument seems right to me, but I have some questions about it.

Bob replied:

I followed your link to Aquinas's take on the subject, and was somewhat startled to find myself disagreeing with him. The issue of future moments is not relevant. We will never arrive at a point an infinite number of years in the future. there is no requirement to traverse that interval, as there is, were there an infinite amount of time in the past (i.e., it has to have happened in actuality, not conceptually).

I had been mistaken, however, in attributing the argument to Islamic sources. Craig and Sinclair wrote:

The kalam cosmological argument traces its roots to the efforts of early Christian theologians who, out of their commitment to the biblical teaching of creatio ex nihilo, sought to rebut the Aristotltelian doctrine of the eternity of the universe. Iin his works Against Aristotle and On the Eternity of the World Against Proclus, The Alexandrian Aristotelian commentator John Philoponus (d. 580?), the last great champion of creatio ex nihilo prior to the advent of Islam, initiated a tradition of argumentation in support of the doctrine of creation based on the impossibility of an infinite temporal regression of events (Philoponus, 1987, Philoponus and Simplicius 1991). Following the Muslim conquest of North Africa, this tradition was taken up and subsequently enriched by medieval Muslim and Jewish theologians before being transmitted back again to Christian scholastic theology.

A layman examines the Lewis-Anscombe controversy

This is a philosophical layperson, obviously well-disposed toward Lewis, who has attempted to analyze and reconstruct the Lewis-Anscombe controversy. Please see "notes" and "appendices."

He is not a fan of mine, as can be seen by these comments from "notes."

Reppert, 59-60. This book is certainly not the “gem” perceived by one reviewer who was perhaps describing what he and I hoped to see rather than what actually lay before him. The title is clever and the opening chapter is inviting; and I guess there is an important truth in the assertion that Lewis is not a provider of finished philosophical products but, rather, of ideas which deserve further devel­op­ment in view of his “outstanding philosophical instincts”. The book contains a couple of useful ideas and distinctions; and it is my abiding impression that the author has the kind of brains and training required for the job and which I lack. Yet I cannot doubt that this book will for most of its readers turn out to be an exercise in “finding out what the author says in spite of all the author does to prevent you” – as C. S. Lewis once described another book whose author had “no order, no power of exposition, no care for the reader”. At any rate, the chapter about the Anscombe affair is a botched job; it was in fact what made me decide to make an attempt myself.

Ouch!

The appendices are very valuable, since they include the original Anscombe critique, and the first edition chapter 3 argument, which are not the easiest things in the world to get a hold of.

Five Concepts of Purpose

When we talk about the purpose for our lives, what are we thinking about? It seems to me that there are five conceptions of what the purpose is.




1) A personal goal. That is, a purpose the person selects, because it satisfies a desire of his own. I decide I want to be a fourth-grade teacher, so I start taking classes at GCU to fulfill that goal.



2) An inherent purpose. Somehow inherent in the object itself is a purpose for existence. If we say the purpose of your eye is to see, perhaps what that means it that the ability to see is part of the nature of eyeness, as it were.



3) A satisfying purpose. It wouldn't make sense to say a rock has a satisfying purpose, but a person is satisfied if it achieves this, and we can also speak of a pig satisfied as well. "You achieved your goal of becoming a millionaire, but you seem dissatisfied nonetheless."



4) A given purpose. Someone who is responsible for our existence has a goal for our existence. This however, might not at all be a purpose that we would select for ourselves. For example, the purpose for which we raise beef cows it for us to eat their meat, which requires us to kill them in order to achieve that purpose. But of course the cows don't want to be killed. On some Calvinistic theological theories, the reason that some people exist is for them to sin and for God to eternally demonstrate his wrath towards them. However, even though those damned to hell achieve the purpose God has for them, they receive no satisfaction from that. One possible thing we might mean when we say that God loves someone, is that we think that the given purpose for their existence, the one God wants for them, is also an inherent purpose and a satisfying purpose.



5) A Darwinian function. A pure Darwinist, one who excludes all intelligent design from the explanation of anything in nature, can say that the purpose of the eye is to see, but what the Darwinian means by that is that the structure of the eye was selected for by the ultimately blind process of natural selection because it made seeing possible, and seeing was helpful in enabling the creature to survive.

Abortion and paternal responsibility

What can be done to equalize the consequences of irresponsible sex? Men can dump their girlfriends and move on, often without consequences. They brag in the locker room, the girls get an embarrasingly oversized stomach and then a child to take care of unless it is given up for adoption or aborted. That is why, I think, women's rights groups have been largely pro-choice.


But what would you say to the idea of aggressively using DNA technology to identify fathers and to require paternal responsibility. What would happen if girls knew that if they carried their child to term and kept it, that the father could have his wages garnished to make sure she could afford to take care of it? And what would that do to guys to make them think twice about jumping into the sack without serious commitment?

It seems to me that this idea should be appealing both to pro-lifers and to feminists. If you think abortion should be safe, legal, and rare, or illegal and rare, you can still agree that this is a good idea.

There has to be something wrong with this idea. It's too practical.

Sure, I'm a physicalist

I can say that physical particles include psychons, angelons, and theons. (The soul, angels, and God). An ideally completed physics will eventually figure out that these things exist, and they will be included in the ontology of physics, so they're physical.

Why can't I say this?

The Argument from Truth: Gordon Clark style

A redated post.

In the late Ronald Nash's Life's Ultimate Questions, he presents an argument from truth for the existence of God which he claims to derive from Augustine but was put into a numbered-premise format by Gordon Clark.

1. Truth exists.
2. Truth is immutable (unchangeable).
3. Truth is eternal.
4. Truth is mental (pertaining to mind or minds).
5. Truth is superior to the human mind.
So 6. Truth is God.

Note that this collection of premises can be formulated into a valid argument (using the modus ponens pattern) as follows:

1. If 1-5 is true, then God exists.
2. 1-5 is true.
So 3. God exists.

This seems to be a different argument from truth from the argument from truth that I developed in CSLDI. Is this a legitimate way of defending theism?
