Interesting question. Yes I guess you could define it as a sound. The sound ...."process".....might not be complete I suppose, without the proper receptor, but the opportunity was still there. This type of question seems intended to produce one train of thought, but it seems to be dangerously inducing another beneathe the surface; "if we remove ourselves from the variable, can we avoid responsibility?" If I stop looking at the light, is it still there? If I don't touch the pot, is it still hot? If I ignore the problem, does it go away? It will always make a sound, that is the way you must see it. wow it's late!
