How we live and learn within our biological sonic limits defines our degrees of freedom. If I am hearing impaired and you are not, we are both determined, but you have greater degrees of freedom.
Let us consider the frequency range of hearing for humans and various selected animals:
|SPECIES||FREQUENCY (hertz) lo-hi|
|Grasshoppers & Locusts||100-50,000|
|Whales & Dolphins||70-150,000|
|Seals & Sea Lions||200-55,000|
The human ear is exquisitely tuned to discern different sound frequencies, whether such tones are high or low, near or far. But the ability of our ears pales in comparison to the way single neurons in our brains distinguish between the very subtlest of frequency differences. Reporting in the Jan. 10 issue of the journal Nature, Dr. Itzhak Fried, professor of neurosurgery and director of the UCLA Epilepsy Surgery Program, and colleagues from Hebrew University and the Weizmann Institute of Science in Israel, show that in humans, while having limits to “ear listening”, a single auditory neuron in the brain exhibits an amazing selectivity to a very narrow sound-frequency range beyond what we ordinarily hear. In other words, our limits are ambiguous, depending on context.
As previously stated, to me the work of Erv Wilson is about freedom – greater degrees of freedom. For there to be any degree of freedom, there must be limits. A distinction is a limit. Our own body structure innately limits our experiences of a universe that is seemingly limitless. Being limited by our bodily structure has led us to innovate extensions of our physical resources: our senses, our ability to see and move in space, to create forms of time, etc. In this way, we have extended ourselves into the world.
