Sartre continued, “Progress is not a constant. It is merely a temporary phase of this universe. I’m no scientist, but the physicists tell us that the universe expands and then collapses and then expands again, not unlike the cosmic cycles envisioned by your Daoist philosophers. Time could easily flow in another direction … or in one of countless directions. Perhaps events can be arranged in any of a number of different sequences, because time may choose from an infinite set of options. Remember the aphorism of Heraclitus: ‘Time is a child playing dice; the kingly power is a child’s.’
