I believe i agree with AaronScythe, if the fetus or organism itself is not a conscious being, then the being itself could not be considered alive. True the heart may beat, and the lungs may breathe, but if there is no brain activity in that equation, then those are just autonomous tasks that the body does without the use of the brain. That's like asking whether or not someone in a slowly declining vegetative state is dead or not, the body it self may be alive, but from what i believe the soul or the anima has already left the hollow shell and passed on
