Pain Poem by ben nourse

what is pain? and where does it lie?
is it buried in just humans? or even in fruit flys?

if true pain can be brought on by physical harm and psychological,
then does that mean it is possible that it may be also theological?

some scientists say pain is a way just to react to a dangerous sensation,
and that the body flinches and vocal chords whine out of painful desperation,

however this theory only covers 'physical pain',
and completely ignores the stabbing of your conscience that drives you insane.
