The end of reason. Unamuno, Life 5.26

Unamuno concludes his chapter on reason by identifying the end of reason as total dissolution, the deconstruction of any basis for action. All actions must carry some motive which reason can analyze, distress, and deconstruct, leaving the agent distrustful of motive, and so of its expression. The end of rational analysis thus becomes paralysis, when we see starkly our mortal limitations, a sight often accompanied by emotional despair. What to do with that? The next chapter will say more.


La disolución racional termina en disolver la razón misma, en el más absoluto escepticismo, en el fenomenalismo de Hume o en el contingencialismo absoluto de Stuart Mill, éste el más consecuente y lógico de los positivistas. El triunfo supremo de la razón, facultad analítica, esto es, destructiva y disolvente, es poner en duda su propia validez. Cuando hay una úlcera en el estómago, acaba éste por digerirse a sí mismo. Y la razón acaba por destruir la validez inmediata y absoluta del concepto de verdad y del concepto de necesidad. Ambos conceptos son relativos; ni hay verdad ni hay necesidad absolutas. Llamamos verdadero a un concepto que concuerda con el sistema general de nuestros conceptos todos, verdadera a una percepción que no contradice al sistema de nuestras percepciones; verdad es coherencia. Y en cuanto al sistema todo, al conjunto, como no hay fuera de él nada para nosotros conocido, no cabe decir que sea o no verdadero. El universo es imaginable que sea en sí, fuera de nosotros, muy de otro modo que como a nosotros se nos aparece, aunque ésta sea una suposición que carezca de todo sentido racional. Y en cuanto a la necesidad, ¿la hay absoluta? Necesario no es sino lo que es y en cuanto es, pues en otro sentido más trascendente, ¿qué necesidad absoluta, lógica, independiente del hecho de que el universo existe, hay de que haya universo ni cosa alguna?

El absoluto relativismo, que no es ni más ni menos que el escepticismo, en el sentido más moderno de esta denominación, es el triunfo supremo de la razón raciocinante.

Ni el sentimiento logra hacer del consuelo verdad, ni la razón logra hacer de la verdad consuelo; pero esta segunda, la razón, procediendo sobre la verdad misma, sobre el concepto mismo de realidad, logra hundirse en un profundo escepticismo. Y en este abismo encuéntrase el escepticismo racional con la desesperación sentimental, y de este encuentro es de donde sale una base —¡terrible base!— de consuelo. Vamos a verlo.


The process of rational dissolution ends by dissolving reason herself, leaving only the most total skepticism: the phenomenalism of Hume, or the absolute contingency of John Stuart Mill, who is the most consequential and logical of the positivists (†). The supreme triumph of reason, an analytical faculty for destruction and dissolution, is to put in doubt its own efficacy. As an ulcer in the stomach will eventually digest itself, so reason ends by unmaking the efficacy of concepts such as truth or necessity, both in the immediate present and in the grand scheme of things. Both of these concepts are relative, relational, contingent. There exists no absolute truth or necessity. We use the word true to mark a concept that accords with the general system of all our concepts, to indicate a perception that does not contradict the total sum of our perceptions. Truth is coherence. Taking that system or sum in its totality, we cannot say whether it is true or not, as we know nothing beyond or outside it. It is very easy to conceive that the universe in itself, beyond our perception of it, is very different from what we apprehend, though this conception lacks all rational sense. As for necessity: is she absolute? A thing is only necessary insofar as it exists, in certain limited circumstances. In a more transcendent sense, what absolute necessity can there be, logically, beyond the fact that the universe exists? Is it really necessary that a universe exist, or that any particular thing within it do so?

Absolute relativism, which is neither more nor less than skepticism in the most modern sense of the word, represents the supreme triumph of reason, the perfection of her work.

As sentiment fails to make consolation true, so reason fails to make truth comfortable. But in the meantime, reason, proceeding on the path of truth, on our fundamental conception of reality, manages to drown herself in deep skepticism. In this abyss, rational skepticism encounters sentimental despair, and from their meeting there arises a foundation—and what a fearful foundation it is!—for consolation. We shall see it.

(†) Hume echoes the ancient Democritus (cf. Galen, De experientia medica 15.7-8; Aristotle, Metaphysica 1009b Bekker) by observing that “vice and virtue may be compared to sounds, colours, heat, and cold, which modern philosophy says are not qualities in objects but perceptions in the mind” (Treatise of Human Nature 3.1.1). John Stuart Mill's views on contingency are well expressed in his book On Liberty (pub. 1859), whose second chapter includes the following passage, which shows what Unamuno means by absolute contingency: “Each individual devolves upon his own world the responsibility of being in the right against the dissentient worlds of other people; and it never troubles him that mere accident has decided which of these numerous worlds is the object of his reliance, and that the same causes which make him a Churchman in London, would have made him a Buddhist or a Confucian in Pekin. Yet it is as evident in itself, as any amount of argument can make it, that ages are no more infallible than individuals; every age having held many opinions which subsequent ages have deemed not only false but absurd; and it is as certain that many opinions now general will be rejected by future ages, as it is that many, once general, are rejected by the present.”
