Other than the "soul" comment (there is, apparently, no such thing. If so, please cite the scientific literature and the Nobel prize winner that reveals it), this is something I can agree with.
Since there are no brainwaves in a blastocyst, then we can agree that embryonic stem cell research is not only appropriate but ethical.
This, by the way, is a blastocyst.
The green cells in the middle are the pluripotent stem cells and necessarily have the potential to divide and become any cell in the body. This is at a stage of perhaps 24-30 hours of development. Not the many weeks required to even notice the first hints of brain development.
These tiny, tiny balls of cells have less intelligence and sentience than bacteria.
