Reason the destroyer. Unamuno, Life 5.2

Unamuno develops further his take on reason. Reason is a tool for deconstructing or analysing contingent experience; it does not recognize premises beyond analysis, incapable of construction. Its pure and natural tendency is thus toward dissolution, disintegration, and eventually death.


Lo que llamamos alma no es nada más que un término para designar la conciencia individual en su integridad y su persistencia; y que ella cambia, y que lo mismo que se integra se desintegra, es cosa evidente. Para Aristóteles era la forma sustancial del cuerpo, la entelequia, pero no una sustancia. Y más de un moderno la ha llamado un epifenómeno, término absurdo. Basta llamarla fenómeno.

El racionalismo, y por éste entiendo la doctrina que no se atiene sino a la razón, a la verdad objetiva, es forzosamente materialista. Y no se me escandalicen los idealistas. Es menester ponerlo todo en claro, y la verdad es que eso que llamamos materialismo no quiere decir para nosotros otra cosa que la doctrina que niega la inmortalidad del alma individual, la persistencia de la conciencia personal después de la muerte.

En otro sentido cabe decir que como no sabemos más lo que sea la materia que el espíritu, y como eso de la materia no es para nosotros más que una idea, el materialismo es idealismo. De hecho y para nuestro problema —el más vital, el único de veras vital—, lo mismo da decir que todo es materia, como que es todo idea, o todo fuerza, o lo que se quiera. Todo sistema monístico se nos aparecerá siempre materialista. Sólo salvan la inmortalidad del alma los sistemas dualistas, los que enseñan que la conciencia humana es algo sustancialmente distinto y diferente de las demás manifestaciones fenoménicas. Y la razón es naturalmente monista. Porque es obra de la razón comprender y explicar el universo, y para comprenderlo y explicarlo, para nada hace falta el alma como sustancia imperecedera. Para explicarnos y comprender la vida anímica, para la psicología, no es menester la hipótesis del alma. La que en un tiempo llamaban psicología racional, por oposición a la llamada empírica, ni es psicología, sino metafísica, y muy turbia, y no es racional, sino profundamente irracional, o más bien contrarracional.

La doctrina pretendida racional de la sustancialidad del alma y de su espiritualidad, con todo el aparato que la acompaña, no nació sino de que los hombres sentían la necesidad de apoyar en razón su incontrastable anhelo de inmortalidad y la creencia a éste subsiguiente. Todas las sofisterías que tienden a probar que el alma es sustancia simple e incorruptible, proceden de ese origen. Es más aún, el concepto mismo de sustancia, tal como lo dejó asentado y definido la escolástica, ese concepto que no resiste la crítica, es un concepto teológico enderezado a apoyar la fe en la inmortalidad del alma.


Soul is just a word for designating the individual consciousness that has integrity and persistence. The fact that this consciousness changes, integrating and disintegrating over time, is evident. For Aristotle, it is the substantial form of the body, its entelechy or expression, but not any substance per se. More than one modern has called it an epiphenomenonabsurd term, as it is enough to call it simply a phenomenon.

Rationalism, by which I mean doctrine that hews strictly to reason and nothing else, aiming only at objective truth, is necessarily materialist. Here I must beg the idealists to check their wrath. We must make everything clear, and the truth is that what we call materialism is simply doctrine that denies the immortality of the individual soul, refusing to grant the persistence of personal consciousness after death.

Taking a different tack, we might say that as our concept of matter is as incomplete and ignorant as any knowledge we have of spirit, so matter becomes for us essentially just another idea, and our materialism is simply idealism. In terms of our problem herethe only truly vital problem, as we have recognized—it is all the same whether everything be matter, or idea, or force, or whatever anyone wants to posit. Every system unified around one single concept will appear materialist to us. Only systems that recognize two principles manage to save the immortality of the soul, teaching that human consciousness is something substantially distinct and different from other phenomena, other material expressions. But reason is not like this: she is naturally unified, aiming for just one principle. Her purpose is to comprehend and explain the universe, an end whose achievement has absolutely no need of a soul at once imperishable and substantial. To explain and understand the life of the conscious mind: this is the rational task of psychology, and it has no need to posit any soul either. What they used to call rational psychology, in opposition to empirical, is not properly psychology at all: it is actually a very confused kind of metaphysics, profoundly irrational—or even better, antirational (†).

Allegedly rational doctrines affirming the substance and spirituality of the soul, with all that accompanies such things, arise historically from the fact that human beings feel a need to provide rational support to their inconquerable desire for immortality, and to the belief that follows this desire. Every neat sophistry trying to prove that soul is a simple and incorruptible substance proceeds from this origin. We can go even further than this. The very concept of substance established and defined by scholastic philosophywhich uses this concept to designate what lies beyond the scope of rational judgment ()is a theological construct crafted to sustain faith in the immortality of the soul.

(†) Medieval Western approaches to the soul, mind, or consciousness (psyche in Greek) yield two competing traditions, Unamuno says, which scholars know as (i) rational psychology and (ii) empirical psychology. Rational psychology posits that there are things we can know a priori, without investigation or proof: these are the premises from which to begin any critical analysis. Empirical psychology says that our only source of knowledge is experience, which relates all things contingently from premises that are always subject to rational scrutiny (and deconstruction, a Latin way of expressing what Greeks call analysis). There is thus no fixed foundation for all investigation. Unamuno's point here is that reason is actually on the side of the empiricists, not the so-called rationalists, as it is properly a tool for taking things apart. Positing premises beyond rational scrutiny—as rationalists do—is antirational, he thinks, contravening the natural tendency of reason to deconstruct all that it conceives.

(‡) Medieval philosophy inherited from antiquity the attempt to resolve the universe into an expression of some basic underlying thing or things. Moderns still speak of elements more or less the same way some of their predecessors did of essence (οὐσία, essentia) or substance (substantia). As the destruction of an individual material object fails to justify the idea that matter or substance is destroyed per se, so some would say that the death of an individual consciousness fails to justify the idea that soul is mortal. Unamuno finds this specious.
