The Thai concern for bioethics has been stimulated by the departure of Thai medicine from its long tradition through the introduction of Western medical models. Bioethics is now being taught to Thai medical students emphasizing moral insights and principles found within Thai culture. These are to a large extent Buddhist themes. Veracity is always a duty for people in general and medical personnel in particular. Falsehoods and deception cannot be morally justified simply on the grounds that we think it is good for another. Buddhism also prohibits killing. The doctrine of kamma holds that joys and sorrows are the result of one's own past actions. Kamma must run its course or will be manifest in a future life. Mercy-killing also violates the Buddhist psychology. A physician who kills subconsciously transfers his aversion to suffering to the one who embodies the suffering. Buddhist justice is understood in terms of impartiality and equal treatment. Compassion goes beyond justice to self-giving and self-denial. It is central to the path to the attainment of highest human fulfillment.
