Deep Time and a Short Life

深遠なる時と短い一生

端末の音声で読み上げ(無料)

The universe is nearly fourteen billion years old, and I have been granted, at most, a few thousand more days.

To set those two numbers side by side is to feel the mind lose its footing on a cliff.

Deep time is not simply a longer version of the time we know; it is a wholly different substance.

Our hours are lived from within, warm and hurried; the eons are seen only from without, cold and silent.

If the whole history of the cosmos were compressed into a single year, humanity would appear in its final seconds.

On that vast calendar, every pharaoh and every philosopher would share the same imperceptible flicker just before midnight.

My own life, measured on such a scale, is briefer than the beat of an insect's transparent wing.

The word , once a poet's ornament, now describes with clinical precision the exact span I have left.

There is a particular in knowing that mountains I called eternal are themselves merely slow, passing weather.

The Himalayas rose and will fall; the very continents drift like foam on a current too slow to see.

Against such patient geology, the whole story of our species is a sentence spoken and forgotten in an afternoon.

For weeks this arithmetic pressed me toward despair, as if were a synonym for worthlessness.

If nothing lasts, a frightened voice within me asked, then why should anything we do be worth the doing?

But deep time, I slowly realised, is a fact about ; it is not, in itself, an argument about value.

A note of music is not made worthless by ending; its very ending is what allows it to be a note.

A song sustained forever, without decay or silence, would not be music at all but only an unbearable siren.

Perhaps our functions less like a punishment and more like the frame that lets a picture .

The stars burn for billions of years, yet not one of them will ever taste a single afternoon.

They endure without experiencing; I experience without enduring, and I am no longer certain which is the poorer fate.

An of blind may be worth less than one September morning consciously and gratefully received.

The stars have but no days; I have days, achingly few, but each of them is genuinely mine.

To be , then, is not to be nothing; it is to be the place where becomes experience.

Deep time gives the cosmos its , but it is short time that gives a single life its unbearable sweetness.

I no longer envy the eons their vast, unfeeling patience, nor mourn that my own thread runs so short.

The eons and my afternoons are not rivals; they are simply two utterly different ways of belonging to time.

When I set my few days beside the eons now, I feel less like a beggar and more like a guest.

A guest does not the party for continuing after he leaves; he is grateful to have been invited.

And so I begin to wonder whether the terror was never in the shortness, but only in how I had measured it.
