It is not a controversial fact that life begins at fertilization.1 For instance, a Princeton University webpage lists fifteen academic sources that support this point. One of the quoted sources clearly states that “fertilization is a critical landmark because, under ordinary circumstances, a new, genetically distinct human organism is thereby formed”.2 An article from PubMed states that “Biologists from 1,058 academic institutions… assessed survey items on when a human’s life begins and, overall, 96% (5337 out of 5577) affirmed the fertilization view [human life begins at fertilization]”.3 I could go on.
So, the abortion debate is now centred on philosophical considerations. One case study will do. Peter Singer, Emeritus Professor of Bioethics at Princeton, answers whether he would save a mouse or human being from a fire: in “almost all cases [he] would save the human being”. Interestingly, the reason for this saving is “not because the human being is human” but because “it matters whether a being is the kind of being who can see that he or she actually has a life — that is, can see that he or she is the same being who exists now, who existed in the past, and who will exist in the future”. Singer’s criteria for something that is worth saving involves some kind of temporal awareness. To explicitly connect this answer to abortion, “no newborn baby is a person” because newborn babies do not have “a sense of the future”.4
