  • Thus if by "potential" one means "potency" - i.e., that the early human embryo already exists with a human nature that is already there, and has its own inherent power or capacity (provided by that human nature) to simply grow bigger and bigger through all the usual developmental stages through birth, then such a statement stands as accurate - both scientifically and philosophically. (lifeissues.net)
  • That is, it would be acknowledging that the human embryo and the human " baby " are the same human being and human person throughout all of his/her development. (lifeissues.net)
  • On the other hand, if by "potential" one means that the human embryo is not a human being or human person yet , but might be later once it has been born (i.e., a "baby"), then that statement is both scientifically and philosophically incorrect. (lifeissues.net)
  • Otherwise, such a treaty would not recognize the inherent human nature of the early human embryo or fetus until after birth , and thus cloning them and using them for research - both "therapeutic" and "reproductive" -- would not be banned, and women undergoing "infertility treatments" could surely be put in danger. (lifeissues.net)
