“It was the meanest moment of eternity.”

"Heroic Reason", as translated by H. R. Hays, in Selected Writings of Juan Ramon Jimenez (1957) edited by Eugenio Florit, p. 231.
Context: A permanent state of transition is man's most noble condition. When we say an artist is in a state of transition, many believe that we are belittling. In my opinion when people speak of an art of transition this indicates a better art and the best that art can give. Transition is a complete present which unites the past and the future in a momentary progressive ecstasy, a progressive eternity, a true eternity of eternities, eternal moments. Progressive ecstasy is above all dynamic; movement is what sustains life and true death is nothing but lack of movement, be the corpse upright or supine. Without movement life is annihilated, within and without, for lack of dynamic cohesion. But the dynamism should be principally of the spirit, of the idea, it should be a moral dynamic ecstasy, dynamic in relation to progress, ecstatic in relation to permanence.

Context: You should not take old people who are already dead seriously. It does them injustice. We immortals do not like things to be taken seriously. We like joking. Seriousness, young man, is an accident of time. It consists, I don't mind telling you in confidence, in putting too high a value on time. I, too, once put too high a value on time. For that reason I wished to be a hundred years old. In eternity, however, there is no time, you see. Eternity is a mere moment, just long enough for a joke.
