No one will ever be able to prove to everyone else's satisfaction that a foetus...at various different stages of its development...is or is not a living human being and/or a living soul. It cannot be proven in any way that will satisfy everyone.

It therefore will remain a matter of individual opinion and a matter of individual faith from here till eternity.

Accordingly, this particular argment will never end...

Too bad the enery it generates could not be used to power some useful device, isn't it? ;-)
