Chet Raymo, "In the Cave"

"In the Cave"
by Chet Raymo

"I have mentioned here before the ospreys that patrol our beach - or "fish hawks," as they call them here - generally in the afternoon at about the time I take my long walk to the palm point. Magnificent birds with broad wings that glide seemingly effortlessly on the wind. And here's the thing: As often as not I am startled by a bird's shadow before I see the bird itself. That wide-winged shadow, sweeping across the white sand, sometimes across me. That flicker of chill as the osprey blocks the sun.

And generally when it happens I think of Plato's allegory of the cave. Prisoners in a cave are constrained to look only at a blank wall. Somewhere behind them there is a fire, and people come and go in front of the fire, casting shadows on the wall. The shadows are the only reality the prisoners know. They have no idea of the flesh-and-blood people behind them or the blazing fire. The prisoners know only what presents itself to their senses.

Forget for the moment Plato's point, which has to do with the duty of the philosopher to enlighten the benighted. There is a humbling moral to the story for all of us: We can only know what our senses - directly or indirectly - can perceive.

Who, a century ago, could have imagined the universe of the galaxies, or the marvelous dance of the DNA in every cell of our bodies? By cleverly extending our senses - limited as they are - with technological enhancements a whole new universe has opened up to us. Who can imagine what we might know a century from now? Plato's "real" world is like a shadow compared to the universe we inhabit today. Our own universe may be a shadow of a reality vastly more wonderful than anything we have so far dreamed.

Never mind. We live in the world we have. Even the osprey's shadow is magnificent in its own way. I am privileged to lift my eyes and see the feathered bird. And I have an intuition that there is more - much more - yet to see.”
