On Life and Entropy

A passage from Diamond Age, by Neal Stephenson:

"Common as the air" meant something worthless, but Hackworth knew that every breath of air that Fiona drew, lying in her little bed at night, just a silver glow in the moonlight, was used by her body to make skin and hair and bones. The air became Fiona, and deserving--no, demanding--of love. Ordering matter was the sole endeavor of Life, whether it was a jumble of self-replicating molecules in the primordial ocean, or a steam-powered English mill turning weeds into clothing, or Fiona lying in her bed turning air into Fiona.
