Killing a Louse on the Sabbath
Question
What do you rule regarding killing a louse on the Sabbath?
(According to the view of the Sages, or according to the scientific knowledge known today?)
And more generally, if there is a contradiction between science and the Sages, and there is a halakhic practical difference depending on each approach, which one do you follow?
Thanks 🙂
Answer
Clearly according to current scientific knowledge, whether that leads to leniency or stringency.
Just as an aside, most halakhic decisors said one should be stringent about this.
