1. "Of the laws we can deduce from the external world, one stands above all: the Law of Transience. Nothing is intended to last. The trees fall year by year, the mountains tumble, the galaxies burn out like tall tallow candles. Nothing is intended to last — except time. The blanket of the universe wears thin, but time endures. Time is a tower, an endless mine; time is monstrous. Time is the hero. Human and inhuman characters are pinned to time like butterflies to a card; yes, though the wings stay bright, flight is forgotten. Time, like an element which can be solid, liquid or gas, has three states. In the present, it is a flux we cannot seize. In the future, it is a veiling mist. In the past, it has solidified and become glazed; then we call it history. Then it can show us nothing but our own solemn faces; it is a treacherous mirror, reflecting only our limited truths. So much is it a part of man that objectivity is impossible; so neutral is it that it appears hostile."
- Brian W. Aldiss, Galaxies Like Grains of Sand
