| its not a scientific problem it is a definition problem. How do you define human life.
Science can be used in the process but ultimately we must define human life. Clearly that sort of definition is on an individual level which can be stretched to a cultural level. Regardless, it does not have a definitive answer. Instead it is answered arbitrarily by societies.
"...all life is an experiment. Every year, if not every day, we have to wager our salvation upon some prophecy based upon imperfect knowledge." -Oliver Wendell Holmes, Jr |
