No god of the gaps. Unamuno, Life 8.5

God, for Unamuno, is not a matter for explanation. Not a means to material ends. Not a locus of human control to be sought in the realm of the physical universe. Knowledge of divinity is not power in the way that knowledge of gravity is. Recognizing gravity better, with greater precision, does not make divinity less or worse or worthless to us.


Era yo un mozo que empezaba a inquietarme de estos eternos problemas, cuando en cierto libro, de cuyo autor no quiero acordarme, leí esto: «Dios es una gran equis sobre la barrera última de los conocimientos humanos; a medida que la ciencia avanza, la barrera se retira». Y escribí al margen: «De la barrera acá, todo se explica sin Él; de la barrera allá, ni con Él ni sin Él; Dios, por lo tanto, sobra». Y en respecto al Dios-Idea, al de las pruebas, sigo en la misma sentencia. Atribúyese a Laplace la frase de que no había necesitado de la hipótesis de Dios para construir su sistema del origen del Universo, y así es muy cierto. La idea de Dios en nada nos ayuda para comprender mejor la existencia, la esencia y la finalidad del Universo.

No es más concebible el que haya un Ser Supremo infinito, absoluto y eterno, cuya esencia desconocemos, y que haya creado el Universo, que el que la base material del Universo mismo, su materia, sea eterna e infinita y absoluta. En nada comprendemos mejor la existencia del mundo con decirnos que lo crió Dios. Es una petición de principio o una solución meramente verbal para encubrir nuestra ignorancia. En rigor, deducimos la existencia del Creador del hecho de que lo creado existe, y no se justifica racionalmente la existencia de Aquél; de un hecho no se saca una necesidad, o es necesario todo.


I was a youth just beginning to worry about these eternal problems, when in some book—I don't want to remember its author—I read this: “God is a great mark upon the final frontier of human knowledge; as science advances, that frontier retreats.” I wrote something in the margin: “On this side of the frontier, everything makes sense without him; on the far side, there is no sense with or without him. God therefore abides, above and beyond this limit.” When it comes to God the idea, the God of proofs, I remain of this same mind. Laplace (†) is supposed to have remarked that the hypothesis of God was unnecessary to the construction of his system illustrating the origin of the Universe, and this is quite correct. The idea of God in no way helps us better understand the existence, essence, and end of the Universe as such.

That there exists a Supreme Being at once infinite, absolute, and eternal, with essence we don't know, and that this being has created the Universe: this idea is no easier to conceive than the idea that the material foundation of the Universe exists eternal, and infinite, and absolute on its own. We understand the world no better merely by affirming that God created it. This affirmation, in itself, is begging the question, offering a purely verbal patch to cover our ignorance of any real answer. In truth, we deduce the existence of the Creator from the fact that creation exists, and there is no rational justification for his own existence. Necessity does not arise from facts; otherwise, all things would be necessary.

(†) Pierre-Simon, marquis de Laplace (1749-1827), is remembered as the French Newton: a scientific genius who extended and developed Newton's view of the heavens, and pioneered the Bayesian approach to probability. Born to a family of relatively wealthy farmers & merchants, his early commitment to a clerical career led him to university, where he remained in service to learning, without formally renouncing religion.
