It was not a simple evil, however. All of medicine, not just cadaver dissection, trespasses into sacred spheres.

In anatomy lab, we objectified the dead, literally reducing them to organs, tissues, nerves,
muscles. On that first day, you simply could not deny the humanity of the corpse. But by the time you’d
skinned the limbs, sliced through inconvenient muscles, pulled out the lungs, cut open the heart, and
removed a lobe of the liver, it was hard to recognize this pile of tissue as human. Anatomy lab, in the
end, becomes less a violation of the sacred and more something that interferes with happy hour, and
that realization discomfits. In our rare reflective moments, we were all silently apologizing to our
cadavers, not because we sensed the transgression but because we did not.
It was not a simple evil, however. All of medicine, not just cadaver dissection, trespasses into
sacred spheres. Doctors invade the body in every way imaginable. They see people at their most
vulnerable, their most scared, their most private.
