[Mark Bahner]

I wrote, "If conjoined twins are born, such that there are two bodies (or parts of bodies), sharing a single brain, do you think that both bodies (or parts of bodies) have a "right to life?" That is, do you think it should be against the law to cut away one body (or part of a body), to produce a single live body and brain?"

Mr. LeRoy responded, "No."

Well, if those bodies, or parts of bodies, have no right to life, why does a collection of cells that ALSO has no brain, have a "right to life?"

if those bodies, or parts of bodies, have no right to life, why does a collection of cells that ALSO has no brain, have a "right to life?"

Because it has the potential to have a reasoning free-willed brain.
