"What if the penis of a living man (and I mean, specifically, his DNA) were actually owned by his ancestors, and his descendents? What if the penis were guided, not by an individual, but by a collective?"

uh... duh. are you at all familiar with the biological imperative to reproduce? this is shared trait at the species level. ALL notions of individuality are just distractions from this condition. do you GENUINELY think that your experiences, down to your internal dialogues, are somehow divorced from this? bags of mostly salt water are we.
