It is recorded in the monastic rules that a monk once performed an abortion on a girl; the Buddha judged his action seriously wrong, which incurred him the highest offense in the monastic rule. A monk committing this kind of wrongful deed must be expelled from the monastic community. The Buddha considered the embryo to be a person like an adult, so the monk who killed the embryo through abortion was judged by Buddhist monastic rules as having committed a crime equal in gravity to killing an adult. In the commentary on the rule stated above, it is stated clearly that killing a human being means destroying human life from the first moment of fertilization to human life outside the womb. So, even though the Buddha himself did not give a clear-cut pronouncement about when personhood occurs, the Buddhist tradition, especially the Theravada tradition, clearly states that personhood starts when the process of fertilization takes place.
This (...) had made me aware for the first time of the well-disguised myth that they and the academic institutions they represent are bastions of a free exchange of ideas. They are -but only of those ideas that don't 'rock the boat', that refrain from challenging hallowed taboos.
