What is meant by alive? That is a hard one. Are sperm alive? Is a non-fertilized egg alive? What is meant by being alive? Is the zygote alive? Is the fetus alive prior to being mature enough to live outside the mother's body? Is life and being alive the same thing or are there shades of both? What is the difference between being alive and having a quality of life? I expect volumes could be written on the philosophy of what does being alive mean. Is it just physical? Is it more than just physical? Note: This is not a discussion about when does life start. It is about the attributes that constitute life and being alive.
