The Battle for Existence. Unamuno, Life 6.9

Unamuno conceives our life as a battle between the heart, which longs to live without dying, and the head, which calculates that this is impossible. In his reading of history, we go through periods of vitalism, when our irrational will to survive forever manifests in worship without great attachment to material forms, and periods of rationalism, when material forms become the most significant culture we possess, because we accept reason and reject immortality. Attempts to harmonize will and reason here must fail, he thinks, as any harmony we achieve turns with time into one of them claiming victory that the other then rises to deny.


El instinto de conocer y el de vivir, o más bien de sobrevivir, entran en lucha. El Dr. E. Mach, en su obra sobre El análisis de las sensaciones y la relación de lo físico a lo psíquico (Die Analyse der Empfindungen und das Verhältniss des Physischen zum Psychischen), nos dice en una nota (I, § 12), que también el investigador, el sabio, der Forscher, lucha en la batalla por la existencia, que también los caminos de la ciencia llevan a la boca, y que no es todavía sino un ideal en nuestras actuales condiciones sociales el puro instinto de conocer, der reine Erkenntnisstrieb. Y así será siempre. Primum vivere, deinde philosophari, o mejor acaso primum supervivere o superesse.

Toda posición de acuerdo y armonía persistentes entre la razón y la vida, entre la filosofía y la religión, se hace imposible. Y la trágica historia del pensamiento humano no es sino la de una lucha entre la razón y la vida, aquélla empeñada en racionalizar a ésta haciéndola que se resigne a lo inevitable, a la mortalidad; y ésta, la vida, empeñada en vitalizar a la razón obligándola a que sirva de apoyo a sus anhelos vitales. Y esta es la historia de la filosofía, inseparable de la historia de la religión.

El sentimiento del mundo, de la realidad objetiva, es necesariamente subjetivo, humano, antropomórfico. Y siempre se levantará frente al racionalismo el vitalismo, siempre la voluntad se erguirá frente a la razón. De donde el ritmo de la historia de la filosofía y la sucesión de períodos en que se impone la vida produciendo formas espiritualistas, y otros en que la razón se impone produciendo formas materialistas, aunque a una y otra clase de formas de creer se las disfrace con otros nombres. Ni la razón ni la vida se dan por vencidas nunca. Mas sobre esto volveremos en el próximo capítulo.


The instinct to know and the instinct to live, or rather to survive, wage constant war against each other. Dr. Ernst Mach (†), in his book on The Analysis of our Feelings, and the Relationship between Matter and Spirit, tells us in a note (1.12) that even the wise researcher fights in the battle for existence, that all the ways of science lead to its front lines, and that the instinct that drives us toward pure knowledge, knowledge for its own sake without any bearing on this war, is but an ethereal ideal. Thus will it ever be. First live, then philosophize, as the Latin proverb says. We could make it better: You must survive, or at least manage to remain alive, before you do philosophy.

Every position that promises lasting harmony or agreement between reason and life, philosophy and religion, becomes in time impossible. Instead, the tragic history of human thought is wholly occupied by war between these principles, with reason seeking to rationalize life by making her surrender to inevitable mortality, while life tries to vivify reason, forcing her to serve and support vital desires. This is also the history of philosophy, inseparable from the history of religion.

Our attitude toward the world, the feeling we hold for its objective reality, is necessarily subjective, human, and calculated to bestow our humanity upon it—at least notionally. So vitalism shall rise forever against rationalism, and will against reason. Hence the rhythm we find in the history of philosophy, which shows us periods of vital will and morbid reason alternating in constant succession: vital will dominates with spiritual forms of culture, until reason ascends and imposes material ones. Each side hides behind new names as time passes, but the same fight goes on. Neither will surrender to the other, ever. We shall revisit the significance of their conflict in the next chapter.

(†) Ernst Waldfried Josef Wenzel Mach (1838-1916) was an Austrian philosopher and physicist, best remembered for his work on shock waves, which produced the Mach number. This number represents the ratio of local velocity in a limited material circumstance to the speed of sound in the medium that occupies that circumstance. As it represents the ratio of two speeds, this number is dimensionless. Mach's philosophy held that material phenomena are best understood as momentary expressions of the actual distribution of matter in the universe (a position that inspired Einstein to posit general relativity). Mach also conducted research in physiology and psychology.
