For an aggregate of sensations to have become a remembrance capable of classification in time, it must have ceased to be actual, we must have lost the sense of its infinite complexity, otherwise it would have remained present.

It is only when they have lost all life that we can classify our memories in time as a botanist arranges dried flowers in his herbarium.
