Document Summary
Can include different types of energy -> light, sound. Sometimes you can only register after a minimum amount is available. Window on the external world is severely constrained. It is difficult to explain the ultimate nature of perception. One way of describing is it through this image. Water of the lakes is murky so the interpreter cannot have direct access to the information they need. Does so by equipping himself with a fishing rod, with a probe that is very sensitive. The encounter with the lake and probe will communicate through vibration etc. to the interpreter so they can analyze and interpret the meaning of the vibration. Probe: represents sensory organs will change as a result with the physical world. Once the probe has been changed after contact with the phsycial world this change has to be communicated to the interpreter. So the virbation is transmitted train of neural impulses has to leave and send info to cns.
