Consensus isn't rational. Unamuno, Life 8.8

Rational proofs of God, for Unamuno, require concepts of reason that will not really do, as they render reason irrational. Here, the proof of universal agreement is really just an appeal to consensus, which is not strictly rational. In the end, Unamuno believes, we must have faith irrationally, beyond and even against reason, which is necessarily mortal in ways that our life instinctively rejects.


Queda la otra famosa prueba, la del consentimiento, supuesto unánime, de los pueblos todos en creer en un Dios. Pero esta prueba no es en rigor racional ni a favor del Dios racional que explica el Universo, sino del Dios cordial que nos hace vivir. Sólo podríamos llamarla racional en el caso de que creyésemos que la razón es el consentimiento, más o menos unánime, de los pueblos, el sufragio universal, en el caso de que hiciésemos razón a la vox populi que se dice ser vox Dei.

Así lo creía aquel trágico y ardiente Lamennais, el que dijo que la vida y la verdad no son sino una sola y misma cosa —¡ojalá!—, y que declaró a la razón una, universal, perpetua y santa. (Essai sur l’indifférence, IVe partie, chap. VIII). Y glosó el «o hay que creer a todos o a ninguno» —aut omnibus credendum est aut nemini—, de Lactancio, y aquello de Heráclito de que toda opinión individual es falible, y lo de Aristóteles de que la más fuerte prueba es el consentimiento de los hombres todos, y sobre todo lo de Plinio (in Paneg. Trajani LXII) de que ni engaña uno a todos ni todos a uno—nemo omnes, neminem omnes fefellerunt.— ¡Ojalá! Y así se acaba en lo de Cicerón (De natura deorum, lib. III, cap. II, 5 y 6) de que hay que creer a nuestros mayores, aun sin que nos den razones: maioribus autem nostris, etiam nulla ratione reddita credere.

Sí, supongamos que es universal y constante esa opinión de los antiguos que nos dice que lo divino penetra a la Naturaleza toda, y que sea un dogma paternal, πάτριος δόξα, como dice Aristóteles (Metaphysica lib. VII, cap. VII); eso probaría sólo que hay un motivo que lleva a los pueblos y los individuos —sean todos o casi todos o muchos— a creer en un Dios. Pero, ¿no es que hay acaso ilusiones y falacias que se fundan en la naturaleza misma humana? ¿No empiezan los pueblos todos por creer que el Sol gira en torno de ellos? ¿Y no es natural que propendamos todos a creer lo que satisface nuestro anhelo? ¿Diremos con W. Hermann (v. Christliche systematische Dogmatik, en el tomo Systematische christliche Religion, de la colección Die Kultur der Gegenwart, editada por P. Hinneberg), «que si hay un Dios, no se ha dejado sin indicársenos de algún modo, y quiere ser hallado por nosotros»?

Piadoso deseo, sin duda, pero no razón en su estricto sentido, como no le apliquemos la sentencia agustiniana, que tampoco es razón, de «pues que me buscas, es que me encontraste», creyendo que es Dios quien hace que le busquemos.


There remains another famous proof, that of the supposedly unanimous agreement of all peoples to believe in one God. But this proof is not rigorously rational, nor is it alleged to support the rational God who explains the Universe. Instead, it backs the God of the heart, who makes us live. We can only call it rational if we can manage to believe that reason is consensus, a more or less unanimous vote by all nations; in that case, we would make reason out to be the voice of the people that claims to be the voice of God.

This is the belief espoused by Lamennais, that tragic and ardent man who said that life and truth are one and the same thing—would that it were so!—and proclaimed a reason at once single, universal, perpetual, and holy (Essay on Indifference 4.8). By way of explanation he added the comment of Lactantius—“We must believe all witnesses or none” (Divinae Institutiones 3.4)—along with the judgment of Heraclitus that every individual opinion is fallible (cf. Sextus Empiricus, Adversus mathematicos 7.133), Aristotle's affirmation that the strongest proof is the assent of all men, and above all the saying of Pliny, that one does not fool all, nor all the one (Panegyricus 62). If only! His credo ends with the passage of Cicero that says we must believe our ancestors, even though they provide us with no reasons to justify belief (De natura deorum 3.2.5-6).

Fine. Let us grant the universality and stable consistency of this opinion of the ancients—an ancestral legacy, as Aristotle says (Metaphysica 7.7)—that informs us that divinity penetrates all Nature. This would prove only that there exists a motive driving peoples and individuals, whether all or almost all or at least very many, to believe in a God. But aren't there then many illusions and fallacies that find their foundation in the same human nature? Don't all peoples begin by thinking that the sun revolves round them? Isn't it natural that we tend to believe what satisfies our longing? Shall we say with Wilhelm Hermann ('Systematic Christian Theology' in Systematic Christian Religion, from the collection edited by Hinneberg, The Culture of our Time) that, “If there is a God, he has not omitted to mark for us his existence, and he wishes by us to be found”()?

A pious wish, certainly, but no reason in the strict sense of the word. Of course we apply here the judgment of St. Augustine, which also is no reason: “The fact that you look for me shows that you have found me” (cf. Confessiones 1). For we believe that God is the one causing us to look for himself.
