Robert P. George, co-author with Christopher Tollefsen of Embryo: A Defense of Human Life, describes for John J. Miller how “at all stages of our lives — from the embryonic through the fetal, infant, child, and adolescent stages and into adulthood — we are human beings with dignity and the right to life. Our dignity does not come from having achieved a certain level of intellectual proficiency or even conscious awareness. … We have our dignity in virtue of the kind of entity we are: that is human being, a creature with a rational nature. And we became that when we came to be.”
