A fully functioning human brain, created just for experimentation. That means that the brain is aware, just like the brain in a 5 week old fetus makes that fetus aware. That is ghastly.
In the 20th century, immoral scientists who conducted horrific experiments caused moral people to respond by creating the field of scientific ethics. It looks like the field of bioethics is due for a sea-change, because there is nothing ethical about creating feeling and aware persons for the explicit purpose of conducting research on them.
Science itself is completely devoid of morals and ethics—like any other academic discipline, it is only a tool for advancement of knowledge. Any ethics or morals associated with the study of science are brought there by the researchers involved. We must never forget that just because something *can* be done, does not mean it *should* be done.
How can the brain be aware if it has no input/output sensory abilities?
