Sea Speaks

We appear as information flows through webs of communications.

A swishing noise behind me becomes a woooosh-THUNK and I damn near knock over the camera, tripod and all. A coconut fell somewhere in the plantation. It sounded close. But sounds are funny at night.

"What about that, Richard, my man?" I say right out loud in a normal speaking voice. "If a coconut falls in the plantation and there is nobody here, is there any sound?" I smile in the darkness of the shadows of the coconut trees. Nobody can see my smile or hear my voice. So perhaps I'm not smiling or really speaking.

"Bishop Berkeley's fatuous philosophic riddle is a mismatch of logical classes," I lecture the coconut trees. "When a coconut falls and nobody is there, is there a sound? What is a sound? What is nobody? How do these two classes relate to each other? This is where the answer lies."

"When a coconut falls, does its impact with the ground create compression waves in the atmosphere?" My class of coconut trees is rigidly attentive. "Yes," one of them nods a frond gently in the wind.

"When the compression waves impact the tympanic membrane of a hominid, is there a series of neural signals associated with the mental model of a coconut impacting the ground?" I pause, but the trees are silent, unsure about human mental models.

"Only if a hominid is within a certain range of the point of impact." I answer for my students and wander down the beach, my arms waving as I discuss all this with the trees, the ants, a couple of mosquitoes, and anybody who might possibly be crazy enough to sit listening to this, hiding in the plantation.

"Suppose we put a video camera with a microphone in the plantation. The coconut falls and the camera records both the image and the sonic compression waves of the impact. There is nobody there. Is there a sound? Is there a sound when later I view the video and hear the thunk? The thunk I hear is not the coconut falling, it is a magnetic pattern on a moving tape translated into an electronic signal and then into a vibrating paper speaker membrane, relayed by the atmosphere to my tympanic membrane and so becomes part of my mental system and associated with the concept of coconut falling in plantation, dynamically illustrated by the video image. So, unless we include the video camera as a somebody, the video evidence shows the good Bishop was wrong. There is a sound in the forest even if nobody is there to hear it." I'm unreasonably pleased with this line of thought although it would probably impossible to actually get a video of a coconut falling.

"We get into logical trouble when we go on beams ends, sliding to one side or the other of a relationship. The sound is not all in the head of the observer. The context, the viewpoint, the perspective, the neuron signal model are all in the head of the observer. But the coconut is not. If a coconut falls on someone's head and the person is immediately knocked out, is there a sound?" Ye Gods! When I think of all the insane patterns of ideas formatting the minds of hominids today it seems a totally impossible task to change them.

Quietly, I walk through the shadows of the coconut trees along the beach, glimpsing the full moon rising higher and higher as the planet spins. I'll get a clear view of it from the end of the beach.
