Argumento de fondo sobre la existencia de Dios

Introducción

Este argumento se originó a partir de dos eventos de entendimiento de mi parte.

El primer evento ocurrió en septiembre de 2014, cuando entendí que la principal de las cinco vías por las que S. Tomás de Aquino demuestra la existencia de Dios, el argumento de contingencia, presupone que la realidad es racionalmente explicable hasta su última instancia, presuposición que en metafísica tiene un nombre: "Principle of Sufficient Reason" (PSR). Ese entendimiento fue explícitamente confirmado al poco tiempo por el filósofo tomista Edward Feser, en un artículo que publicó en su blog el 2 de noviembre de 2014:

"Now if PSR is false, then the principle of causality is threatened as well, since if things are ultimately unintelligible, there is no reason to think that a potency might not be actualized even though there is nothing actual to actualize it and thus that something contingent, like the universe, might just be without any cause at all.  But then it would not be possible to argue from the world to God as cause of the world."

El segundo evento ocurrió en agosto de 2015, cuando entendí que el PSR equivale al teísmo o lo presupone. Esto lo presenté como "thesis 1" en el artículo “Thesis 1: holding the PSR is equivalent to, or presupposes, holding theism”.

Por lo tanto las cinco vías no demuestran realmente la existencia de Dios, porque presuponen lo que quieren demostrar. (En realidad, dado que parten de la presuposición de un teísmo difuso, demuestran estrictamente que, si la realidad es racionalmente explicable hasta su última instancia, esa última instancia es el Dios inmutable del teísmo clásico que creó el universo de la nada, y no la divinidad del panenteísmo, de cuya sustancia habría emanado el universo, o por lo menos las almas.)

Hechos comprobados y disyuntiva

En definitiva, ante los siguientes hechos (facts) comprobados:

F1: el universo existe y, como un todo, es una entidad contingente: podría ser distinto, podría no existir. Más aún:

F2: el universo comenzó a existir hace 13.800 millones de años, y no hay una teoría científica sólida que ofrezca una causa física de ese comienzo. Hay solamente conjeturas no verificables como el multiverso. (Por otro lado, un universo cíclico que se expande hasta un máximo, luego se contrae hasta un mínimo, y así sucesivamente, es una alternativa positivamente invalidada por las observaciones acumuladas desde 1998 que demuestran concluyentemente que la expansión del universo se está acelerando y por lo tanto va a continuar indefinidamente.)

F3: el universo funciona causalmente y de acuerdo a leyes expresables matemáticamente.

F4: las constantes físicas del universo exhiben una sintonía fina que lo hace adecuado para el desarrollo de organismos vivientes complejos.

F5: la mente humana razona en base a causalidad y es capaz de crear sistemas formales matemáticos, incluyendo obviamente los que expresan las leyes que describen el funcionamiento del universo.

cada ser humano puede adoptar una de dos posiciones posibles, la primera de las cuales explica racionalmente los hechos y la otra simplemente los acepta como "brute facts":

Posición SR (Spiritual-Rational)

Existe en última instancia una Realidad Subsistente que es Espíritu y Razón (Logos), que creó el universo (explica F1 y F2) conforme a esa Razón (explica F3) con el fin de albergar el desarrollo de criaturas racionales (explica F4), cuya razón es creada a imagen de la Razón increada (explica F5).

Posición ME (Materialist-Evolutionist)

F1 ... F3: “brute fact”, “that’s just the way it is”. “Es así”, y esperar o demandar que tenga explicación es una presuposición a priori totalmente injustificada. (Ver las posiciones de David Hume, Bertrand Russell y Sean Carroll en el artículo anterior.)

F4: la sintonía fina puede deberse a que hay muchísimos universos, en cuyo caso es obvio que solamente en aquellos universos con parámetros aptos para el desarrollo de la vida puede desarrollarse la vida. O tal vez no haya muchos universos, y simplemente, al igual que con F1 ... F3, “that’s just the way it is.”

F5: la capacidad de la mente humana fue resultado de la evolución: el cerebro alcanzó una complejidad suficiente para permitir el pensamiento abstracto, sin que intervenga ningun alma espiritual. En cuanto a la causalidad, el mono que pensó que la rama se movió sin causa fue comido por un león.

Comparación de las posiciones

Las posiciones son totalmente opuestas en dos aspectos: explicación y sentido, tanto del universo como, mucho más importante, de la vida humana.

En la posición SR el universo tiene explicación y la vida humana tiene sentido, perdurando luego de la muerte.

En la posición ME el universo no tiene explicación y la vida humana no tiene sentido, terminando en la muerte. Ni siquiera tiene sentido la humanidad en su conjunto, porque es bien sabido que a lo sumo en 2.000 millones de años el sol habrá calcinado la tierra.

Conclusión

Expresaré la conclusión citando dos discursos de Benedicto XVI, no como argumento de autoridad sino porque hago míos esos párrafos. En primer lugar resumo la situación citando de:

http://w2.vatican.va/content/benedict-xvi/es/speeches/2006/april/documents/hf_ben-xvi_spe_20060406_xxi-wyd.html

Por último, para llegar a la cuestión definitiva, yo diría:  Dios o existe o no existe. Hay sólo dos opciones. O se reconoce la prioridad de la razón, de la Razón creadora que está en el origen de todo y es el principio de todo -la prioridad de la razón es también prioridad de la libertad- o se sostiene la prioridad de lo irracional, por lo cual todo lo que funciona en nuestra tierra y en nuestra vida sería sólo ocasional, marginal, un producto irracional; la razón sería un producto de la irracionalidad. En definitiva, no se puede "probar" uno u otro proyecto, pero la gran opción del cristianismo es la opción por la racionalidad y por la prioridad de la razón. Esta opción me parece la mejor, pues nos demuestra que detrás de todo hay una gran Inteligencia, de la que nos podemos fiar.

Pero a mí me parece que el verdadero problema actual contra la fe es el mal en el mundo:  nos preguntamos cómo es compatible el mal con esta racionalidad del Creador. Y aquí realmente necesitamos al Dios que se encarnó y que nos muestra que él no sólo es una razón matemática, sino que esta razón originaria es también Amor. Si analizamos las grandes opciones, la opción cristiana es también hoy la más racional y la más humana. Por eso, podemos elaborar con confianza una filosofía, una visión del mundo basada en esta prioridad de la razón, en esta confianza en que la Razón creadora es Amor, y que este amor es Dios.

Luego amplío la descripción de la opción por la racionalidad citando de:

http://w2.vatican.va/content/benedict-xvi/es/speeches/2007/july/documents/hf_ben-xvi_spe_20070724_clero-cadore.html

Pero la doctrina de la evolución no responde a todos los interrogantes y sobre todo no responde al gran interrogante filosófico: ¿de dónde viene todo esto y cómo todo toma un camino que desemboca finalmente en el hombre? Eso me parece muy importante. En mi lección de Ratisbona quise decir también que la razón debe abrirse más: ciertamente debe ver esos datos, pero también debe ver que no bastan para explicar toda la realidad. Nuestra razón ve más ampliamente. En el fondo no es algo irracional, un producto de la irracionalidad; hay una razón anterior a todo, la Razón creadora, y en realidad nosotros somos un reflejo de la Razón creadora. Somos pensados y queridos; por tanto, hay una idea que nos precede, un sentido que nos precede y que debemos descubrir y seguir, y que en definitiva da significado a nuestra vida.

Así pues, el primer punto es: descubrir que realmente nuestro ser es razonable, ha sido pensado, tiene un sentido; y nuestra gran misión es descubrir ese sentido, vivirlo y dar así un nuevo elemento a la gran armonía cósmica pensada por el Creador. Si es así, entonces los elementos de dificultad se transforman en momentos de madurez, de proceso y de progreso de nuestro ser, que tiene sentido desde su concepción hasta su último momento de vida.

Thesis 1: holding the PSR is equivalent to, or presupposes, holding theism

It is well established that holding the PSR is a requirement for the classical arguments for the existence of God [1]. I hereby propose the thesis that holding the PSR is equivalent to, or presupposes, holding theism. Not necessarily full-fledged classical theism, but at least a basic, less clear-cut version thereof.

Thesis 1: holding the principle of sufficient reason (PSR), which states that “there is a sufficient reason or adequate necessary objective explanation for the being of whatever is and for all attributes of any being” [2], or alternatively that "for every fact F, there must be an explanation why F is the case" [3], either is equivalent to holding the following two notions, or presupposes holding them:

R1. Subsistent, Ultimate Reality is logos, i.e. reason. [4]

R2. Human reason is created in the image of the uncreated Logos.

Of course, the two notions above are held in conjunction with this:

R3. Created reality was created according to reason. [5]

which is clearly consistent with the observable fact that the universe works causally according to mathematically expressible laws.

A panentheist can hold these notions by replacing "created" with "created/emanated" in R2 and R3. I mention this possibility to allow for panentheism as alternative "bootstrap" position or entry point, which could then, by reasoning on the PSR, be corrected into classical theism. Which makes sense considering the numbers of Taoists, Mahayana Buddhists, Hinduists and Sikhs.

Noting that Prof. Feser stated that "to see the world as intelligible or rational through and through is implicitly to be a (classical) theist" [6], the basis for a possible demonstration of Thesis 1 is: why else should we assume that reality is ultimately rational? This can be perceived more clearly if we examine the alternative interpretation of observed facts that a materialistic evolutionist could propose instead of that based on the PSR, either in its traditional form or in the form of the Rx above (which is equivalent to the traditional form if this thesis is correct):

M1. Brute fact: the universe exists and works causally according to laws expressed mathematically.

M2. The rationality of our mind, i.e. the agreement between the way it works and the way the universe works, was selected by evolution. Because, on seeing the branches of a bush moving in windless weather:
- the walking-talking apes who thought the movement had a cause got ready to fight or flee, survived, and passed on their genes.
- the walking-talking apes who thought the movement did not have a cause did nothing, and were killed by a rival tribe or an animal.

M3. At some point, some of the walking-talking apes that were so evolutionary successful because, among other things, the way their mind worked conformed to the way the universe worked, got the big picture the other way round, and thought that it was the way the universe worked which conformed to the way their mind worked. That would have had no practical consequence, but some of them went even further, and claimed that their mind was able to explain reliably not only the way the universe worked, but even why there was a universe! And the apes called that statement the Principle of Sufficient Reason, and they rejoyced greatly.

"Hey, walking-talking ape, who do you think you are?"

---

This thesis originated from my realization on Sep. 2014 that the modal cosmological argument, or argument from contingency, is just the principle of efficient causality (PC), and that the PC in turn is based on just the Principle of Sufficient Reason, the latter statement being confirmed by Prof. Feser on Nov. 02, 2014 [1]. Thus, the teaching in First Vatican Council's Constitution "Dei Filius" "that God, the source and end of all things, can be known with certainty from the consideration of created things, by the natural light of human reason "for his invisible attributes, ever since the creation of the world, have been clearly perceived, being understood through the things that have been made."" (ch. 2 "On Revelation", which in turn quotes (Rom 1:20)) presupposes the implicit condition "if the person in question assumes that reality is ultimately intelligible/explainable by human reason".

Now, whereas philosophy is about the rational explanation of reality, the assumption that reality is ultimately rationally explainable is meta-philosophical, i.e. holding the PSR is a meta-philosophical choice. Thus, the issue of theism vs atheism is not really philosophical but meta-philosophical, as the latter position is based on the assumption that reality is not ultimately rationally intelligible/explainable. Which is exactly David Hume's position as summarized by Texas A&M University Prof. of Philosophy Stephen H. Daniel [7]:

"The argument assumes that the world's existence can be explained rationally by appeal to God as its cause; but why should we think that the world's existence is rationally explainable?"

Or Bertrand Russell's position in his famous debate with Fr. F. C. Copleston [8]:

"R: The whole concept of cause is one we derive from our observation of particular things; I see no reason whatsoever to suppose that the total has any cause whatsoever.

R: what I'm saying is that the concept of cause is not applicable to the total.

R: I should say that the universe is just there, and that's all.

R: for my part, I do think the notion of the world having an explanation is a mistake. I don't see why one should expect it to have,

C: But your general point then, Lord Russell, is that it's illegitimate even to ask the question of the cause of the world?

R: Yes, that's my position."

Or Prof. Sean Carroll's position, as stated in 2007 [9]:

"There is a chain of explanations concerning things that happen in the universe, which ultimately reaches to the fundamental laws of nature and stops. ... There is a strong temptation to approach the universe with a demand that it make sense of itself and of our lives, rather than simply accepting it for what it is."

and again in 2012 [10]:

"It’s okay to admit that a chain of explanations might end somewhere, and that somewhere might be with the universe and the laws it obeys, and the only further explanation might be “that’s just the way it is.” ... I could be wrong about that, but an insistence that “the universe must explain itself” or some such thing seems like a completely unsupportable a priori assumption."

Argument from contingency is Principle of Causality and requires PSR and just PSR

In http://www.thesumma.info/one/one29.php , Fr Reginald Garrigou-Lagrange (GL) writes about the principle of causality, or more precisely the principle of efficient causality:

As a matter of fact, this principle is commonly formulated not only in the phenomenal but also in the ontological order, and not only does it state that "every phenomenon supposes an antecedent phenomenon," but it also says: "Everything that comes into being has a cause"; or rather, to express it more universally, every contingent being is efficiently caused by another. Even if de facto this contingent being eternally existed, it would still need a productive and conservative cause, because a contingent being is not its own reason for existence.

Comparing it with the modal cosmological argument, or argument from contingency, as stated by Prof. Edward Feser in:

http://edwardfeser.blogspot.com/2011/07/so-you-think-you-understand.html

What defenders of the cosmological argument do say is that what comes into existence has a cause, or that what is contingent has a cause.

it is clear that the modal cosmological argument as stated by Prof. Feser is identical to the principle of efficient causality as stated by Fr GL. This is confirmed by another text from Fr GL at:

http://www.thesumma.info/reality/reality5.php

The principle of efficient causality also finds its formula as a function of being. Wrong is the formula: "Every phenomenon presupposes an antecedent phenomenon." The right formula runs thus: "Every contingent being, even if it exists without beginning, [137] needs an efficient cause and, in last analysis, an uncreated cause."


Back to the first link from Fr GL, he attempts to show that "one cannot deny the principle of causality without denying the principle of contradiction."

First he argues that "uncaused contingent being is repugnant to reason. In other words, nothing is what results from nothing, without a cause nothing comes into being." However, the second statement, while obviously true, does not prove the first, because an uncaused contingent being does not NEED to have "come into being", it could just have always existed. (To accommodate current science, that would be a hypothetical "metaverse" undergoing eternal inflation, in which "pocket universes" such as ours would pop up here and there.)  That would mean that such a being would be a brute fact and not explainable by reason, which is not the same as "repugnant to reason". In other words, that possibility would be against the Principle of Sufficient Reason (PSR) but not against the principle of (non-)contradiction (PNC) as Fr GL argues.

Fr GL repeats his argument in the same paragraph:

Why is an uncaused contingent being repugnant to reason? It is because a contingent being is that which can either exist or not exist (this being its definition). Therefore it is not self-existent, and must be dependent upon another for this; otherwise, if it were neither self-existent nor dependent upon another for existence, it would have no reason for existing, and so would be the same as nothing. "Nothing is what results from nothing." To say that from nothing, or that from no cause either efficient or material, something comes into being, is a contradiction.

IMV, there are three non-sequiturs in this paragraph.

First, that a being "can either exist or not exist" means that it does not have in itself the reason for its existence. However, that does not imply that "it is not self-existent", but rather that "it is not self-existent IF reality is rationally explainable". Therefore, a contingent being can be either a self-existent brute fact, if reality is not rationally intelligible, or dependent upon another for its existence, if reality is rationally intelligible.

Second, Fr GL is right when he says that if a contingent being "were neither (rationally intelligibly, I add) self-existent nor dependent upon another for existence, it would have no reason for existing". However, that does not entail that such a contingent being "would be the same as nothing".  Because to "have no reason for existing", to be a brute fact, is not the same as to "be the same as nothing". Not being rationally explainable is not the same as not being.

Third, Fr GL is right when he says that: ""Nothing is what results from nothing." To say that from nothing, or that from no cause either efficient or material, something comes into being, is a contradiction." However, a contingent universe (or metaverse) could just have always existed without having ever come into being, so that its existence, while being a brute fact and as such against the PSR, would not imply a contradiction.

Summarizing, then, a contingent being is that which can either exist or not exist (by definition), so that, when referring to the universe (or metaverse), there are three posibilities:

a. it is dependent upon the Subsistent Being for its existence, (in which case both the PNC and the PSR hold),
b. it exists by itself, and has always existed, as a non-rationally intelligible brute fact, (in which case the PNC holds but the PSR does not),
c. it has come into being from nothing, as a brute fact repugnant to reason, (in which case neither the PNC nor the PSR holds).

From this, two conclusions:

First, as the modal cosmological argument, or argument from contingency, is just the principle of efficient causality, it is based on just the PSR [1] and does not require the aristotelical framework of act and potency. This is an important result, because otherwise St Paul's statement that "since the creation of the world God's invisible attributes, his eternal power and divine nature, are clearly seen, being understood through the things that are made" (Rom 1:20) would need to be restated as "since Aristotle wrote his Metaphysics God's invisible attributes, his eternal power and divine nature, are clearly seen, being understood through the things that are made".

Second, it seems that the teaching in First Vatican Council's Constitution Dei Filius "that God, the beginning and end of all things, can be known with certainty by the natural light of human reason from created things;" as well as the above Pauline statement that Dei Filius quotes right next as basis for that teaching, presupposes the implicit condition "if the person in question assumes that reality is ultimately intelligible/explainable by human reason". [2]

Thus, the issue of theism vs atheism (agnosticism) would not be really philosophical but meta-philosophical, as the latter positions would be based on the assumption that reality as a whole is not (necessarily) rationally intelligible/explainable.

Which is exactly David Hume's position as summarized by Texas A&M University Prof. of Philosophy Stephen H. Daniel [3]:

"The argument assumes that the world's existence can be explained rationally by appeal to God as its cause; but why should we think that the world's existence is rationally explainable?"

And which is the basis of the "Thesis 1" that I propose on the next article.

[1] That PSR is sufficient for PC was confirmed by Prof. Edward Feser in an article he published in his blog on 2014 09 06:

a Scholastic might (as some Neo-Scholastic writers did) argue for PC on the basis of the principle of sufficient reason (PSR). 

[I]f PC were false — if the actualization of a potency, the existence of a contingent thing, or something’s changing or coming into being could lack a cause — then these phenomena would not be intelligible, would lack a sufficient reason or adequate explanation. Hence if PSR is true, PC must be true.

Sola scriptura is against Scripture, specifically four Pauline passages

First, not everything which was revealed by God was transmitted in writing by the Apostles, at least definitively not by Paul:

"So then, brothers, stand firm and hold to the traditions that you were taught by us, either by our spoken word or by our letter."  (2 Thess 2:15)

"Follow the pattern of the sound words that you have heard from me, in the faith and love that are in Christ Jesus." (2 Tim 1:13)

"and what you have heard from me in the presence of many witnesses entrust to faithful men who will be able to teach others also." (2 Tim 2:2)

The objection to sola scriptura from the three above passages could be ingeniously countered by positing that any knowledge that Paul transmitted only orally and which needed to be transmitted to future generations was put in writing by some other NT author, be it John, Peter, James, Jude, or Luke in Acts. I don't think any sola scriptura defender would actually resort to such convoluted argument, but even if they did, they'd still need to explain away this other passage from Paul:

"the Church of the living God, the pillar and support of the truth." (1 Tim 3:15)

In this passage, "support", rendered alternatively as "foundation", "bulwark" or "buttress", translates "hedraióma", a word used only once in the NT and nowhere else. To note, the usual word for "foundation" is "themelios", used in several places by Paul to refer to:

- Jesus Christ (1 Cor 3:10-12),
- the apostles and prophets (Eph 2:20), "Christ Jesus Himself being the cornerstone (akrogóniaios)" in this case, and
- those who belong to God, i.e. the Church: "God's firm foundation stands, bearing this seal: "The Lord knows those who are his,"" (2 Tim 2:19).

The relationship between Jesus, the apostles and the whole of the Church in these passages with "foundation"/"themelios" mirrors the relationship between Jesus, Peter and the totality of the faithful in four passages with "rock" or "stone", namely those where:

- Paul and Peter call Jesus "the cornerstone", i.e. Eph 2:20 and 1 Pe 2:6-7 respectively, the latter using both "akrogóniaios" and "kephale gonias",
- Jesus tells Simon: "you are Rock (Kepha/Petros), and upon this rock (kepha/petra) I will build my church" (Mt 16:18), and
- Peter says that the faithful "as living stones, are being built up as a spiritual house" (1 Pe 2:5).

The teaching from either set of passages is clear:

- Jesus is the ultimate foundation, the cornerstone, and it is so by Himself, by nature.
- Peter and the apostles are foundation by the grace of Christ, by participation in his firmness.
- The whole Church, "built on the foundation of the apostles and prophets" (Eph 2:20), is also foundation and support by participation.

The point is that it is the Church which is "the pillar and support of the truth", not Scripture. This statement, together with the quoted Pauline exhortations to hold to the traditions received orally from him, show clearly that the position of sola scriptura is against Scripture.
