Eruvin 74

וְאַיְבוּת בַּר אִיהִי סָבַר: מְקוֹם פִּיתָּא גָּרֵים. וּשְׁמוּאֵל לְטַעְמֵיהּ דְּאָמַר: מָקוֹם לִינָה גָּרֵים.

And Ivut bar Ihi holds that the place where a person eats his bread determines his place of residence. Therefore, he did not consider the synagogue a residence, as the attendant would eat elsewhere, and Ivut bar Ihi thought that Shmuel had permitted him to set up a side post for his alleyway even though he lived there by himself. In fact, however, this was not the case, as Shmuel followed his regular line of reasoning, as he said: The place where a person sleeps determines his place of residence. Since the attendant would sleep in the synagogue, it was considered a residence. Consequently, the alleyway contained two houses and courtyards, and could be made permitted for carrying by means of a side post or a cross beam.

I must say, I was really stumped to find anything psychological on this Daf, so bear with me if I am stretching things a bit. The name “iyvut bar ihiy” is rare in the Gemara. He is not called Rav, though he seems to have a degree of standing amongst the great Amoraim such as Shmuel. What we do know is that is there are two other Amoraim, who also are sons of iyhi, and also rarely mentioned. One such instance is an interesting story in Kesuvos 61a, which also has bearing to a superb Rambam and Kesef Mishne:

אבוה בר איהי ומנימין בר איהי חד ספי מכל מינא ומינא וחד ספי מחד מינא מר משתעי אליהו בהדיה ומר לא משתעי אליהו בהדיה

It is related about two Sages, Avuh bar Ihi and Minyamin bar Ihi, that one of them was accustomed to give his waiter from every type of food that he ate, while the other one would give him only one of the types of food that he ate. The Gemara says: Elijah spoke with this Sage, but Elijah did not speak with that Sage, since he did not act with piety and caused his waiter to suffer.

It is also interesting to note that at least one of these bar iyhi were circumspect regarding compassion and food. Could this possibly be related to the opinion of iyvus bar iyhi in our Gemara that holds makom pisa gorem, the place where he eats determines residence for Eiruv purposes ?

No, you might think that this courtesy applies to a Jewish attendant. However, Rambam as understood by Kesef Mishne,  uses this Gemara as a source for his humanistic approach and how to treat slaves:

Laws of Servants 9:8

It is permissible to work a heathen slave relentlessly. Even though it is lawful, the quality of benevolence and the paths of wisdom demand of a human being to be merciful and striving for justice. One should not press his heavy yoke on his slave and torment him, but should give him to eat and drink of everything. The sages of old were in the habit of sharing with the slave every dish they ate, and they fed the cattle as well as the slaves before they themselves sat down to eat.— — Nor should a master disgrace his servant by hand or by words; the biblical law surrendered them to servitude, but not to disgrace (Niddah 47a). He should not madly scream at his servant, but speak to him gently and listen to his complaints.— — Cruelty is frequently to be found only among heathen who worship idols. The progeny of our father Abraham, however, the people of Israel upon whom God bestowed the goodness of the Torah, commanding them to keep the laws of goodness, are merciful toward all creatures. So too, in speaking of the divine attributes, which he has commanded us to imitate, the psalmist says: "His mercy is over all his works" (Psalm 145:9). Whoever is merciful will receive mercy, as it is written: "He will be merciful and compassionate to you and multiply you" (Deuteronomy 13:18).

ומ״ש חכמים הראשונים היו נותנים לעבד מכל תבשיל ותבשיל וכו'. בירושלמי פרק החובל אהא דאמר רבי יוחנן הקוטע יד עבד חבירו רבו נוטל נזקו וצערו ריפוי שבתו ובשתו והא רבי יוחנן אכיל קופר ויהיב לעבדיה שתי חמר ויהיב לעבדיה וקרי אנפשיה הלא בבטן עושני עשהו אמרי תמן במדת הדין ברם הכא במדת רחמים ובגמרא דידן פרק אע״פ (כתובות דף ס״א) אבוה בר איהי ומנימין בר איהי חד ספי מכל מינא ומינא וחד ספי מחד מינא מר אשתעי אליהו בהדיה ומר לא משתעי אליהו בהדיה הנהו תרי חסידי וכו' מר מקדים ספי ומר מאחר ספי דקדים ספי משתעי אליהו בהדיה דמאחר ספי לא משתעי אליהו בהדיה ובס״פ הניזקין (גיטין דף ס״ב) אסור לאדם שיטעום כלום עד שיתן מאכל לבהמתו שנאמר ונתתי עשב בשדך לבהמתך והדר ואכלת ושבעת:

I must say, when I read this piece carefully, I think to myself, “One day, after 120 years, I hope they will say that I treated my family members as well as Rambam says I should treat a slave.“
