One famous account in the Talmud (Shabbat 31a) tells about a gentile who wanted to convert to Judaism. This happened not infrequently, and this individual stated that he would accept Judaism only if a rabbi would teach him the entire Torah while he, the prospective convert, stood on one foot. First he went to Shammai, who, insulted by this ridiculous request, threw him out of the house. The man did not give up and went to Hillel. This gentle sage accepted the challenge, and said:
"What is hateful to you, do not do to your neighbor. That is the whole Torah; the rest is the explanation of this—go and study it!"
The perspective of Shammai reminds me of the stereo sales agent who talks in terms of features: 5.1 sound, number of speakers, bass output, whatever. Hillel meanwhile is the person who understands the job to be done – just make it sounds good.
