To Save a Life

One mantra that is often repeated in halacha is that nothing supersedes saving a life. Therefore, it is somewhat surprising that a recent Gemara (Kesubos 39a) seems to take a contrarian view.
The question addressed by the Gemara is whether a certain intervention, which might very well be ordinarily prohibited, can be prescribed to prevent a life-threatening condition from developing. Rebbe Meir rules in the affirmative, exactly as we would have expected. (Or perhaps he holds that the intervention is not actually prohibited.) Astonishingly, the Sages disagree. They say that the individual should not use the halachically forbidden intervention. Instead, the individual should rely on the verse in Tehillim (116:6), “Hashem protects the simpletons.” How could the Sages disregard the threat to human life and possibly allow a life-threatening situation to develop?
The answer is the subject of much debate. The reader is forewarned that no practical conclusions may be drawn from this article especially in matters of life and death. This article is intended simply to engender discussion.
