“Maybe the most sacred function of memory is just that: to render the distinction between past, present, and future ultimately meaningless; to enable us at some level of our being to inhabit that same eternity which it is said that God himself inhabits.”

Variant: For in the final analysis, our most basic common link, is that we all inhabit this small planet, we all breathe the same air, we all cherish our children's futures, and we are all mortal.

Context: In short, both the United States and its allies, and the Soviet Union and its allies, have a mutually deep interest in a just and genuine peace and in halting the arms race. Agreements to this end are in the interests of the Soviet Union as well as ours — and even the most hostile nations can be relied upon to accept and keep those treaty obligations, and only those treaty obligations, which are in their own interest. So, let us not be blind to our differences — but let us also direct attention to our common interests and to the means by which those differences can be resolved. And if we cannot end now our differences, at least we can help make the world safe for diversity. For, in the final analysis, our most basic common link is that we all inhabit this small planet. We all breathe the same air. We all cherish our children's future. And we are all mortal.

"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.
