Are we really talking about a 'life?' At what point does a life begin? Is terminating a foetus, which can neither feel nor think and is not conscious of its own 'existence,' really commensurable with the killing of a 'person?' There rightly are restrictions on the time, within which a termination can take place, before a foetus does develop these defining, human characteristics. If you affirm that human life is a quality independent of, and prior to thought and feeling, then you leave yourself the awkward task of explaining what truly 'human' life is. A foetus is not a life until it fulfils certain criteria. Before 24 weeks, a foetus does not feel pain, is not conscious of itself or its surroundings. Until a fetus can survive on its own, it cannot be called a life, any more than the acorn can be called a tree.
