Scientists rightly resist invoking the supernatural in scientific explanations for fear of committing a god-of-the-gaps fallacy (the fallacy of using God as a stop-gap for ignorance). Yet without some restriction on the use of chance, scientists are in danger of committing a logically equivalent fallacy-one we may call the chance-of-the-gaps fallacy. Chance, like God, can become a stop-gap for ignorance.
Sounds travel through space long after their wave patterns have ceased to be detectable by the human ear: some cut right through the ionosphere and barrel on out into the cosmic heartland, while others bounce around, eventually being absorbed into the vibratory fields of earthly barriers, but in neither case does the energy succumb; it goes on forever - which is why we, each of us, should take pains to make sweet notes.
And still, for all the jealously, all the doubt, sometimes I will be struck with a kind of awe that we're together. That someone like me could find someone like you --- it renders me wordless. Because surely words would conspire against such luck, would protest the unlikelihood of such a turn of events.
