"Diseases usually appear to us as something unexpected, due to the so called "default" state of good health. The difficulty of measuring health is in the fact that the majority of existing indicators are negative, that is, they serve to measure the absence of health. Good health, contrarily, can be seen as an accidental anomaly, not as an intrinsic attribute, and even less, as a "right" of humans. In the face of a disease, what we habitually call "life" is an effort to survive, "to resist," "to maintain oneself," "to persist," "to endure," "to persevere." The fundamental ethical issue consists in that, as potential creators of another human being's life, we cannot make predictions about the mechanisms of survival of the possible being, their vulnerability to the structural pain. We have no moral right in making a standardized prediction about this vulnerability. The sinister happiness (sinister and superficial) with which our society welcomes pregnancy and birth, must necessarily confront its own ethical categories, if we are profound in our reflection."
