Reason won't grant immortality. Unamuno, Life 5.9

Unamuno recounts the history of modern attempts to argue rationally for the soul's immortality, starting with the Renaissance and its aftermath. He finds the humanist reading of Aristotle more convincingly rational than the scholastic, when it comes to the soul's mortality, and dismisses nineteenth-century spiritualism (which argued that souls might be immortal because we observe them communicating with mediums, psychics, and others, in various circumstances we can observe).


A partir del Renacimiento y la restitución del pensamiento puramente racional y emancipado de toda teología, la doctrina de la mortalidad del alma se restableció con Alejandro Afrodisiense, Pedro Pomponazzi y otros. Y en rigor, poco o nada puede agregarse a cuanto Pomponazzi dejó escrito en su Tractatus de inmortalitate animae. Esa es la razón, y es inútil darle vueltas.

No ha faltado, sin embargo, quienes hayan tratado de apoyar empíricamente la fe en la inmortalidad del alma, y ahí está la obra de Frederic W. H. Myers sobre la personalidad humana y su sobrevivencia a la muerte corporal: Human personality and its survival of bodily death. Nadie se ha acercado con más ansia que yo a los dos gruesos volúmenes de esta obra, en que el que fué alma de la Sociedad de Investigaciones psíquicas—Society for Psychical Research—ha resumido el formidable material de datos, sobre todo género de corazonadas, apariciones de muertos, fenómenos de sueño, telepatía, hipnotismo, automatismo sensorial, éxtasis y todo lo que constituye el arsenal espiritista. Entré en su lectura, no sólo sin la prevención de antemano que a tales investigaciones guardan los hombres de ciencia, sino hasta prevenido favorablemente, como quien va a buscar confirmación a sus más íntimos anhelos; pero por esto la decepción fué mayor. A pesar del aparato de crítica, todo eso en nada se diferencia de las milagrerías medievales. Hay en el fondo un error de método, de lógica.


Ever since the Renaissance and the restoration of thought that is purely rational, emancipated of all theology, the doctrine of the soul's mortality has resumed its old position of dominance, taken in antiquity by Alexander of Aphrodisias (†) and fortified more recently by Pietro Pomponazzi (‡), as well as others. In terms of rigor, there is really nothing left to add to what Pomponazzi left us written in his Treatise on the Immortality of the Soul. In his take we find reason herself, and it is useless to fight against her.

Still, some have sought to support faith in the immortality of the soul with empirical observation. Here we find the work of Frederic W. H. Myers (*) on Human Personality and Its Survival of Bodily Death. Nobody has approached the two thick volumes of this work with more anxiety than I. In them, that which was the soul of the Society for Psychical Research has taken the shape of a formidable collection of facts: episodes of spontaneous premonition, apparitions of the dead, strange dreams, telepathy, hypnotism, involuntary seizures, ecstasies, and the entire spiritualist arsenal. I began reading without any of the prejudice men of science are accustomed to keep against such investigations; indeed, I was favorably disposed, as one looking to confirm his most intimate desires. But this only made my disappointment worse. Despite coming equipped with a critical apparatus, the project holds nothing that you couldn't find in medieval accounts of miracles. There is an error of method, of logic, in its most basic conception.

(†) Alexander (fl. second century CE) was a philosopher in the Peripatetic tradition, hailing originally from the city of Aphrodisias in Caria, whence he came in time to Athens, where he became head of the Lyceum. He left behind various writings, mostly commentaries on Aristotle, and produced a strong Peripatetic argument for the mortality of the soul.

(‡) Pietro Pomponazzi (1462-1525 CE) studied medicine at the University of Padua, becoming first a doctor and then a natural philosopher. When the War of the Holy League interrupted the life of Padua in 1509, he went to the University of Ferrara, where he taught on Aristotle, and finally in 1512 to the University of Bologna, where he stayed and published his works, including the treatise on the soul cited by Unamuno. He remained a committed Catholic his entire life and was not censured by the church for his explicit beliefs (i) that Aristotle did not teach the immortality of the soul, contrary to what Aquinas says, and (ii) that reason does not compel us to accept the immortality of the soul.

(*) Born into a British family of industrial magnates turned clergymen, Myers (1843-1901) was educated as a classicist at Cheltenham College and Trinity College, Cambridge, where he took his degree along with several prizes (including one he returned under suspicion of plagiarism) and a fellowship. Eventually, he became a state inspector of schools (a professional bureaucrat). After losing faith in the religion of his parents, he sought some basis for religion in spiritualism, and founded with others the society whose publication Unamuno read. The spiritualists were notoriously gullible, as their history of dealing with mediums and psychics like Douglas Blackburn and Eusapia Palladino shows.
