How can the abortion issue be resolved? Many believe that the issue can be resolved if, and only if, we can determine when human life begins. Those opposed to abortion choice typically say that human life begins at conception. Many who favor abortion choice say that we will never know when human life begins. The importance of the when-does-human-life-begin issue is not so much argued for as it is taken to be self-evident. Furthermore, belief that this issue is fundamental is taken for granted – at least outside of philosophy – by many of the people who seem to disagree about almost everything else concerning abortion. It has been my experience that – with rare exceptions – even those who insist that the issue of abortion should focus on the interests of pregnant women believe that this focus is warranted because fetuses are either not yet fully alive or not yet fully human.
