“Philosophy is an everlasting fire, sometimes damped down by setting itself limits, then flaring into new life as it consumes them. Every field of inquiry is limited, but philosophy has an essential relation to the question of limits, to its own limits.”

Dune Genesis (1980)
Context: No matter how finely you subdivide time and space, each tiny division contains infinity.
But this could imply that you can cut across linear time, open it like a ripe fruit, and see consequential connections. You could be prescient, predict accurately. Predestination and paradox once more.
