THIS IS A HONEYCOMB WORLD.

It hides a hollow heart. The truth of nature, wrote the philosopher Democritus, lies in deep mines and caves. The stability of what is seen and felt beneath our feet is an illusion, for this life is not as it seems. Below the surface, there are cracks and fissures and pockets of stale, trapped air; stalagmites and helactites and unmapped dark rivers that flow ever downward. It is a place of caverns and stone waterfalls, a labyrinth of crystal tumors and frozen columns where history becomes future, then becomes now.

For in total blackness, time has no meaning.

The present is imperfectly layered on the past; it does not conform flawlessly at every point. Things fall and die and their decay creates new layers, thickening the surface crust and adding another thin membrane to cover what lies beneath, new worlds resting on the remains of the old. Day upon day, year upon year, century upon century, layers are added and the imperfections multiply. The past never truly dies. It is there, waiting, just below the surface of the now. We stumble into it occasionally, all of us, through remembrance and recall. We summon to mind former lovers, lost children, departed parents, the wonder of a single day when we captured, however briefly, the ineffable, fleeting beauty of the world. These are our memories. We hold them close and call them ours, and we can find them when we need them.
