"Just, for a moment, meditate on the extraordinary improbability: a raw and tiny rock, hurtling through the heavens whilst growing a fragile, living skin; and that skin deciphering how to join the fiery firmament, how to leap between the stars … reaching out towards infinity… ∞ If we must talk of freedom, let us talk about that world. For that is the world we live in, if we could but see it."
