“In general, there are no preconceptions about what is the correct conduct for all situations, since the correctness of a way of being is itself only measurable in terms of a specific set of circumstances that may or may not recur.
There is therefore no possibility of fixing a single standard of behavior.
If anything is clear, it is that a rigid, unchanging way is wrong”
–Rabbi Adin Steinsaltz
