The unstated assumption here is that anyone who thinks that using these embryos is unjust because they believe the embryo is already a baby, does not care about the lives currently being affected by these diseases that need cures. There is also an unstated assumption that embryos are not alive and therefore what happens to this “ball of cells” does not really matter. There is an assumption that these embryos are a key factor in finding treatment for these diseases.
The statement is for harvesting embryos by assuming that the reader agrees with the fact that embryos are not alive and that they are not human beings yet. Having to appeal to a reader is an important part in writing and this particular paragraph would probably not appeal so much to mothers. Some might argue that these harsh unstated assumptions about the audience of this passage would affect the overall opinion and reactions to it.
