Eruvin 72  The power of permission- כח דהתירא עדיף

 
As Newton taught us, every action has an equal and opposite reaction.
While this might apply not only in physics, when it comes to human societal behaviour, non-equal and overreaction is also common.
The Rambam (Deos 1,2) teaches us that a person should avoid extreme characteristics and rather aim for the “golden mean.”
For example, a person should not be so emotional that he is angered by everything, yet he also does not have to be emotionally cold like a piece of wood in that he feels nothing.
He should not be so careful with his money that he is scared to spend anything but should also not be such a spend-thrift that he just gives or throws everything away.
The Rambam also notes that it is sometimes necessary for a person to move to the opposite extreme of an attribute that he has obtained an extreme dose of, in order to eventually reach an equilibrium and return to the middle path of balance.
When it comes to the question of how strict to be when it comes to disputes or “grey areas” in halacha, or how many voluntary “chumras” (stringencies) to take on, there is also a wide spectrum in the behaviour of observant Jews.
Some tend to be extreme in their observance, always choosing the strictest view as well as taking on any extra voluntary stringencies they can come up with.
Others, tend to take a minimalistic approach, always choosing the most lenient approach and avoiding anything that might not be an absolute obligation, even if it has some religious value.
Although we find a range of approaches amongst our greatest Rabbis as well (Beis Hillel and Beis Shamai perhaps being the greatest example, and of course we rule like Beis Hillel, though not necessarily for that reason) the accepted approach amongst Chazal seems to be somewhere in-between, the general rule being in cases of doubt or unresolved dispute, we are stringent in biblical matters and lenient in rabbinical matters.
However, on our daf, as well as numerous other places in the Shas, we find a rule that many have taken (whether correctly or incorrectly is subject to debate) as a call to look for leniencies wherever possible.
This principle is referred to be Chazal as כח דהתירא עדיף- the strength (or scope)  of permission is preferred.
It is important to note that many  cases in Shas that involve this principle seem to follow a similar basic pattern- it is a little complex, but please bare-with me, as understanding this structure is essential to understanding this sugya, many others, and the very principle that is the subject of this post.
Stage 1 : We start with a debate regarding a certain case, between two authorities, where the one (let us call him “Rabbi X”) permits or validates something and the other (let us call him ”Rabbi Y”) forbids or invalidates it.
Stage 2 : The Gemara then focusses on the precise conditions under which the debate applies, and someone suggests that under seemingly less stringent conditions, even the stringent opinion would be lenient (or under seemingly more stringent conditions, even the more lenient opinion would be stringent.)
Another view might then counter that the debate applies to both the seemingly more lenient and seemingly more stringent case.
 
Stage 3 : The Gemara then brings a Beraita, Mishna, or other authoritative text that seems to show that the debate only applies under the more stringent (or lenient) conditions, thus challenging the later view that views the debate more broadly.
Stage 4: The Gemara then answers on behalf of the later view, showing that the reason that the proof-text records the debate under the more stringent conditions is to show the   “כח”  (strength or scope) of the more lenient view in that his lenient ruling extends even to the more stringent case, and by way of קל וחומר (fortiori deduction,) obviously to the more lenient case. However, the stringent view is not necessarily limited to the more stringent case and might also extend to the more lenient case.
Stage 5: The Gemara then questions why, if the above argument is true, the proof-text did not rather record the debate under the more lenient conditions to show the “כח” of the more stringent view in that his stringent ruling extends even to the more lenient case, and by way of קל וחומר, obviously to the more stringent case. Then, the lenient view would not necessarily be limited to the more lenient case but could possibly extend to the more stringent case.
Stage 6: The Gemara answers that when given the choice which case to use to illustrated the debate, the proof-text prefers to choose the case that which shows the scope of the lenient view, rather than the case which shows the scope of the stringent view, in its words, כח דהתירא עדיף- we prefer to illustrate the scope of the lenient view over that of the stringent view.
 
Although the daf includes other view and discussions, I will attempt to  select the parts that are part of this core pattern, and use it as a case-study for this principle. Where the pattern of the sugya deviates from this basic pattern, I shall also attempt to point it out and adapt it as best as I can.
Stage 1 : We start with a debate regarding a certain case, between two authorities, where the one (let us call him “Rabbi X”) permits or validates something and the other (let us call him ”Rabbi Y”) forbids or invalidates it.
The Mishna on Eruvin 72a discusses the case where 5 different groups people all spend shabbos in one טרקלין, which seems for the purposes of this post to refer to one villa consisting of one very large room.
This טרקלין  in turn opens to a courtyard which is shared by other houses.
It is obvious that the inhabitants of the טרקלין need to participate in the ערוב חצירות together with the other inhabitants of the courtyard.
The question is, however, whether these 5 groups are to be considered as one as far as the eruv is concerned, and may contribute once to the general eruv on behalf of all 5 groups, or whether each group needs to give its own contribution.
Beit Shamai holds that each group needs to give its own contribution, whereas Beis Hillel hold that all 5 groups may give one contribution together.
For purposes of our “pattern” Beis Shamai is the stringent  “Rabbi Y” who does not allow one contribution to be given on behalf of all 5 groups, and Beis Hillel is the lenient “Rabbi X” who does permit it.
Stage 2 : The Gemara then focusses on the precise conditions under which the debate applies, and someone suggests that under seemingly less stringent conditions, even the stringent opinion would be lenient (or under seemingly more stringent conditions, even the more lenient opinion would be stringent.)
Another view might then counter that the debate applies to both the seemingly more lenient and seemingly more stringent case.
The Gemara considers what the conditions are like in the טרקלין, in other words, how it is divided up.
Rav Nachman suggests that the debate only applies when the room is divided up by a מסיפס (an inferior type of partition-acc to Rashi, “a low partition made of pieces of wood” but see commentaries on  Bava Basra 2b for different definitions).)
However, under more stringent conditions namely if the room is divided by proper מחיצות (halachically valid partitions,) even Beis Hillel (Rabbi X) agree that they are viewed as separate groups and each one needs to make its own contribution to the eruv.)
The Gemara brings a different version of Rav Nachman’s view where he states that the debate applies to both situations, whether the room is divided by a מסיפס  (the lenient case)  or מחיצות (the stringent case)
[the Gemara then deviates from the standard binary dispute and brings another dispute regarding whether the debate applies to a case where the partitions reach the roof or to a case where they do not- for purposes of this illustration, I shall skip this.)
Stage 3 : The Gemara then brings a Beraita, Mishna, or other authoritative text that seems to show that the debate only applies under the more stringent (or lenient) conditions, thus challenging the later view that views the debate more broadly.
 
 
The Gemara brings the view of the Tana Rabbi Yehuda haSabar who states explicitly that the debate refers to a case where the partitions did not reach the roof, but that if they do reach the roof, even Beis Hillel is stringent and requires an eruv contribute from each group.
[This is accepted as a proof in favor of the Amora who suggested that the dispute is limited to the more lenient case where the partitions do not reach the roof, and against the Amora who says that the dispute is limited to the more stringent case where the partitions do reach the roof.]
For our purposes, this is viewed as a proof against the first view of Rav Nachman that the debate is limited to the (more lenient) case where the room is divided by a מסיפס as we see that the debate clearly applies to the (more stringent)  case where it is divided by partitions that do not reach the roof as well.
The Gemara further suggests that it should be a proof against the second version of Rav Nachman’s opinion who says the debate applies to both a room divided by a מסיפס and by regular partitions, seeing as there is no mention of a  מסיפס  in the statement of Rabbi Yehuda haSabar, seemingly implying that in a lenient case like that, even Beis Shamai would permit one contribution for all.
Stage 4: The Gemara then answers on behalf of the later view, showing that the reason that the proof-text records the debate under the more stringent conditions is to show the   “כח”  (strength or scope) of the more lenient view in that his lenient ruling extends even to the more stringent case, and by way of קל וחומר (fortiori deduction,) obviously to the more lenient case. However, the stringent view is not necessarily limited to the more stringent case and might also extend to the more lenient case.
The Gemara answers for Rav Nachman that the reason Rabbi Yehuda haSabar discusses the case of partitions and not the case of a מסיפס is to show the scope of Beis Hillel (the more lenient view) that permits one eruv for all of them even in the case of a partition that does not reach the roof (and by קל וחומר  to the more lenient case of the מסיפס.)
However, Beis Shamai (the stringent view) might indeed also forbid this even in the case of the מסיפס (the less stringent view,) in which case Rav Nachman view that the debate applies to both cases can be upheld.
Stage 5: The Gemara then questions why, if the above argument is true, the proof-text did not rather record the debate under the more lenient conditions to show the “כח” of the more stringent view in that his stringent ruling extends even to the more lenient case, and by way of קל וחומר, obviously to the more stringent case. Then, the lenient view would not necessarily be limited to the more lenient case but could possibly extend to the more stringent case.
The Gemara then questions why, if the above argument is true, Rabbi Yehuda haSabar did not rather discuss a  מסיפס (which reaches the roof as opposed to one which does not) in order to show the כח  of Beis Shamai (the more stringent view) in that his ruling applies even to the case of a מסיפס (the more lenient case) (and by קל וחומר  to the more stringent case of the מחיצה .)
Then, the lenient view of Beis Hillel might not necessarily be limited to the more lenient case of the מסיפס but COULD well extend to the more stringent case of the מחיצה ( so long as it does not reach the roof.)
Stage 6: The Gemara answers that when given the choice which case to use to illustrated the debate, the proof-text prefers to choose the case that which shows the scope of the lenient view, rather than the case which shows the scope of the stringent view, in its words, כח דהתירא עדיף- we prefer to illustrate the scope of the lenient view over that of the stringent view.
The Gemara answers that (Seeing as either way, the כח of one view will be illustrated and the other will remain subject to doubt,) it is preferable to show the scope of the lenient view.
 
Although the precise pattern might deviate from sugya to sugya, most of  the most essential elements thereof remain similar in other sugyas where this principle is brought, for example regarding making the Bracha “Shehecheyanu” on clothes which he bought for the second time (Brachos   60a), an egg that was laid on Yom Tov (Beitza 2a), the baby of a טריפה  animal (Chullin 58a), and a double doubt  (ספק ספיקא)  regarding Niddah (Niddah 59b.)
It seems clear that this principle does not serve as blanket guidance for following a generally lenient approach to halacha, but rather illustrates the important of going as far as possible to show the full scope of a lenient opinion, at least one that is halachically authoritative.
However, if there was not some value in allowing people to be lenient, or some issue with simply advising people to be stringent, this principle nevertheless seems somewhat spurious- after all what is the urgency of showing the scope of the lenient view over the scope of the stringent view if it serves no practical purpose?
If it was simply about דרוש וקבל שכר (learning Torah for the sake of the truth and obtaining merit for it,) it should be equally important to know the precise scope of the stringent opinion!
As such, extending this principle beyond Talmudic debates to going out of one’s way to find a halachically valid lenient approach to things seems somewhat justifiable, and many poskim have indeed appeared to do so (see for example Tzemach Tzedek 103 [regarding agunos], Seridei Eish 2/4 (regarding stunning animals before slaughter during the Nazi era.)
Examining the words of Rashi (Beitza 2a,) we get some clues as to what the rational for this principle is.
“טוב לו להשמיענו כח דברי המתיר, שהוא סומך על שמועתו ואינו ירא להתיר, אבל כח האוסרין אינה ראיה, שהכל יכולין להחמיר, ואפילו בדבר המותר”
It is good for him to teach us the scope of the words of the lenient view, because he relies on his tradition and is not afraid to permit. But the scope of the prohibitors is not a proof, as anyone can be stringent, even in something that is permitted.”
This wording appears to be somewhat ambiguous (for example, is the phrase  “שהוא סומך…” referring to the lenient view or the one interpreting him) and the way we interpret it might have major ramifications as to how we understand the reasons and scope of this principle.
Other issues essential for this discussion are the question of whether this principle also applies where the halacha does not follow the lenient view (such as Beis Shamai in Beitza- see Tosfos on our daf for a starting point) and whether this principle applies even to debates regarding rabbinical laws where the default is to be lenient anyway (see צל”ח  ביצה ב.. who claims that it does not, how he explains the exception in that case, and examine whether our sugya might possibly serve as a counter example to his view [after all, eruv is rabbinical and ספק עירוב לקולא !])
I would love to continue, but its already been 5 pages, and I am way behind on the current dapim, so I leave this as a challenge for further study, and  Hashem willing, we shall get to revisit the subject next time we encounter this principle.
 
These posts are intended to raise issues and stimulate further research and discussion on contemporary topics related to the daf. They are not intended as psak halacha.

Eruvin 7 A philosophy of stringencies or leniencies


There is a tendency in parts of the Torah world to err on the side of caution in all halachik matters and take on the more stringent opinions in all areas of halacha.
On the other hand, there is a tendency amongst other sectors to constantly search for  leniencies, picking and choosing the easier opinion in each area of halacha.
Are either of the above policies legitimate, or is one perhaps required to choose one or more recognized halachik authorities and follow their views in every area of halacha, irrespective of whether they are lenient or stringent?
On the previous daf, we recorded a dispute between Rav and Shmuel regarding how to close off a מבוי מפולש (alley open to the public domain at both ends.)
Rav ruled leniently like the Tana Kama in the beraisa and held that a צורת הפתח (form of an entrance) on one end and a pole or beam on the other end was sufficient.
On the other hand, Shmuel ruled stringently like Beis Hillel according to Chananya, and held that a צורת הפתח was not sufficient on the one side, but doors were required.
We also saw a different dispute, also between Rav and Shmuel, regarding a    מבוי עקום (bent alley.)
Until then, we had been dealing solely with a straight, rectangular מבוי, closed along its lengths and open either on one or two ends.
This dispute, however, centered around an “L” shaped מבוי that makes a right-angled turn in the middle, but is still open at both ends.
As such, the one end is not aligned with the other, and it is unclear whether such a מבוי  is to be treated at each end as if it is only open on that end, making a pole or beam sufficient, or whether it is to be treated like a מבוי open on both ends to a public domain, and thus require one of the more stringent solutions discussed in the Beraisa .
In this case, Rav is stringent, and holds that it is to be regarded as open on both sides (מפולש), whereas Shmuel is lenient and treats it as if it is only open on one side (סתום).
When we combine both disputes, it comes out that such a מבוי does not require doors according to either Rav or Shmuel.
This is because:
1.       Although Rav rules that it is to be treated like a מבוי מפולש (open alley), he also rules like the Tana Kama that a מבוי מפולש (open alley) does not require doors on either side.
2.       Although Shmuel rules that a מבוי מפולש requires doors on one side, he rules that such a מבוי עכום is to be treated like a מבוי סתום (closed alley.)
 
Despite the fact that we have thus not found ANY authority who holds that a מבוי עכום  requires doors, the Gemara tells us that there was such a מבוי  in the city of Neharda, Shmuel’s home town, and the authorities treated it with the stringencies of both Rav and Shmuel, requiring doors on one side!
This means essentially that they “collected” the stringencies of both, treating it like an open מבוי in accordance with Rav, and requiring an open מבוי to have doors in accordance with Shmuel.
The Gemara is extremely bothered with this approach of collecting חומרות (stringencies,) due to a Beraisa that focusses on general principles applying to disputes between בית הלל and בית שמאי.
The Beraisa rules that the law is in accordance with Beis Hillel in all cases. Yet, one is permitted to choose which of them to follow (the Gemara later explains that this was only before the בת קול  (voice from heaven) that proclaimed that the law is always like Beis Hillel, or according to the view of Rabbi Yehoshua who did not accept the authority of voices from heaven, or that this statement refers to similar disputes amongst later sages that have not yet been resolved.)
The Beraisa, however, condemns those who rely on the leniencies of both of them, calling them “wicked,” and mocks those who follow the stringencies of both of them, applying to them the verse הכסיל בחושך הולך (“the fool walks in darkness”- Koheles 2.)
On today’s daf, 2 approaches are given to explain how the authorities in Neharda had not behaved like “fools” by being stringent like both opinions:
1.       Rav Nachman bar Yitchak is of the view that in practise, even Rav would not be lenient and accept only a צורת הפתח, a claim made already by Rav Huna.
2.       Rav Shizvi seeks to explain this even according to the view of Rav Ada bar Ahava that Rav was indeed lenient in practise. He interprets the Beraisa’s application of the term “fools” to those who practise the stringencies of both houses in a far more limited fashion.
He claims that this only applies when the two disputes are inter-connected, with the lenient view in the one case logically requiring a stringent view in the other, and vice versa.
Where the two debates are completely independent of one another, there is no issue with practicing the stringencies of both.
 
To support the second approach, Rav Shizvi brings the case of the “spine and the skull,” discussed in a Mishna (Ohalos 2/3)
This Mishna deals with the bones of a corpse that are considered like the whole corpse itself and cause everything in the same אהל (covered area) to become impure.
In contrast, most bones on their own do not cause such impurity, and only cause impurity to things that touch them.
It is universally accepted that the whole spine and whole skull, being the most essentially bones of the body, are treated with the stringencies of the body itself, and make everything under the same roof of them impure.
If the spine or skull is no longer whole, however, they are treated more leniently like any other bone.
There is a dispute between בית הלל and בית שמאי regarding how much of the spine or skull needs to be missing for it to no longer be considered whole.
Regarding the spine, בית שמאי holds that unless at least 2 vertebrae are missing, it is still considered whole and the more stringent rules of impurity apply. בית הלל, on the other hand, hold that as soon as one vertebrae is missing, the spine is no longer considered whole and the more lenient rules of impurity apply.
Regarding the skull, בית שמאי are once again stringent and hold that it still considered whole unless enough is missing to cause death in a living person.
בית הלל once again are more lenient, and say if the amount normally removed by a doctor’s drill (possibly in therapeutic  surgery) from a live person is missing from the dead man’s skull, it is already considered incomplete.
Rav Shizvi then refers to the ruling of Rav Yehuda in the name of Shmuel that the same criteria apply to the laws of טריפות (terminally injured animals.)
Missing pieces in the spine and skull before slaughter are counted amongst the terminal injuries that render an animal non-kosher even after proper slaughter.
In order for it to be considered “incomplete” and thus non-kosher, בית שמאי use the more stringent criteria they applied to a corpse, essentially making it harder for it to be considered non-kosher. This turns out effectively to be a leniency in the rules of kashrus.
בית הלל in contrast, use the more lenient criteria they use to release the spine and skull from the more stringent laws of impurity, in effect making it easier for the animal to be considered non-kosher, and thus creating a stringency in the laws of kashrus!
This means that in this case, a leniency in one area of halacha, namely impurity, logically requires a corresponding stringency in a different area, namely the laws of kashrus, and vice versa.
Thus being stringent in both areas, and applying the stringent laws of impurity to a spine missing only one bone, but also considering an animal with such a spine to be non-kosher, is logically inconsistent, as is applying the lenient laws of impurity but also considering it to be kosher.
In such cases, says Rav Shizvi, being stringent like both opinions is logically inconsistent and thus foolish.
A generally cautious and stringent approach to halacha in which the stringencies of different authorities are adopted is thus not considered like a “fool walking in the darkness”  according to his interpretation of the Beraisa, unless it leads to logically inconsistency in one’s behaviour.
It is not stringency per se that is the issue, but logically inconsistent behaviour.

A spine missing one vertebra is either considered whole or not, but cannot be both whole and incomplete.

In order to develop a broader approach to this issue, a number of questions need to be raised, among them:
1.       IS Rav Shizvi’s interpretation of the Beraisa only brought in order to reconcile Rav Ada bar Ahava’s view that Rav was lenient in practise regarding a צורת הפתח in a מבוי מפולש, but Rav Nachman bar Yitchak would still prefer the original and  simpler interpretation of the Beraisa that considers collecting stringencies in general to  be a foolish and dark approach?
2.        If this is not so, we would need to explain why Rav Nachman bar Yitchak doesn’t make the obvious distinction that Rav Shizvi makes and instead chooses a view of Rav that is subject to debate.
3.       If Rav Nachman bar Yitchak indeed favors the original and simple approach, do we accept his broader view of the “fool in the dark” or the more limited interpretation of Rav Shizvi?
4.       If Rav Shizvi’s distinction is to be accepted, does this apply only to the Beraisa’s mockery of the chronic מחמיר  (one who is stringent) or does it also apply to the Beraisa’s condemnation of the chronic מקיל   (one who is lenient.) On the one hand, he only makes the distinction regarding stringency, but the need for consistency within the wording of the Beraisa seems to indicate that it applies equally to leniencies. If this is so, he would see no “wickedness” in “collecting” leniencies from different authorities, so long as they are not logically inconsistent with each other.
 
 
Answering these questions requires a thorough study of all parallel and related sugyos  and the Rishonim who comment on them. As this is way out of the scope of this post, we shall have to wait for future opportunities to revisit this topic!
