(a) In a responsum, REBBI AKIVA EIGER (in TESHUVOS REBBI AKIVA EIGER 3:80)
praises the questioner for his suggestion that women are exempt only from
Mitzvos Aseh which involve an action ("Kum v'Aseh"). He writes that this has
a strong logical basis.
This view can is also expressed by the PNEI YEHOSHUA in Beitzah (30a) and by
the K'SAV SOFER (OC 56). The K'sav Sofer adds that this conforms with the
logic of the AVUDRAHAM for why women are exempt from Mitzvos Aseh
sheha'Zeman Gerama. The Avudraham explains that the reason women are exempt
is because they are too busy to be limited to a certain time during which to
do a Mitzvah. A Mitzvah which is accomplished passively (by not doing
anything -- "Shev v'Al Ta'aseh") -- even though it is limited to a certain
time -- does not limit the woman and she is able to fulfill the Mitzvah
while still fulfilling her other obligations. (See Insights to 35a.)
A practical consequence of this might be whether women are obligated to
observe the additional Inuyim Yom Kipur other than the Inuyim of eating and
drinking (such as washing, wearing leather shoes, and marital relations),
according to those opinions which hold that the Inuyim are all d'Oraisa. The
Lo Ta'aseh, and the liability for Kares, for transgressing the Inuyim of Yom
Kipur apply only to eating and drinking. If women are exempt from all
Mitzvos Aseh, even those that are fulfilled passively, then they should be
exempt from the other Inuyim of Yom Kipur. If, however, women are exempt
only from Mitzvos Aseh that are performed actively, then they should be
obligated to observe the additional Inuyim, so those are Mitzvos Aseh which
are done passively. See MINCHAS CHINUCH (313:1).
Another practical consequence is whether women are obligated to observe
Tosefes Shabbos, according to those who hold that it is a Mitzvas Aseh
d'Oraisa (see Rosh Hashanah 9a). If women are exempt from all Mitzvos Aseh,
then they should be exempt. If, however, women are exempt only from Mitzvos
Aseh that are performed actively, then they should be obligated to fulfill
the Mitzvas Aseh of Tosefes Shabbos. (This practical consequence is more
relevant with regard to Tosefes Yom Tov and Tosefes Yom Kipur. With regard
to Tosefes Shabbos, women certainly should be obligated because of the
Hekesh of "Shamor" and "Zachor" which obligates women in all Mitzvos of
Shabbos that apply to men. See MINCHAS CHINUCH 297:3.)
(b) However, REBBI AKIVA EIGER and the K'SAV SOFER, as well as the TZELACH
(Beitzah 30a; see also SHITAH MEKUBETZES there), point out that the Gemara
does not seem to differentiate between a Mitzvas Aseh performed actively
("Kum v'Aseh") and a Mitzvas Aseh performed passively ("Shev v'Al Ta'aseh").
The Gemara in Sukah (28b) cites a verse to show that women are obligated to
observe Tosefes Inuy on Yom Kipur. The Gemara explains that we might have
thought that women are exempt: since there is no Lo Ta'aseh or Kares for
transgressing Tosefes Inuy, therefore (since it is only a Mitzvas Aseh)
women should not be obligated in the Mitzvah, had the verse not included
them (with the word "ha'Ezrach"). It seems clear from the Gemara there that
women would be exempt even from passive Mitzvos Aseh, such as Tosefes Inuy,
unless the verse says otherwise.
Perhaps we can argue that the Mitzvah of Inuy on Yom Kipur is not a passive
Mitzvah, but it is an active one. It is active because the person is
required to change from his normal way of acting by accepting the Tosefes
Inuy and stopping himself from eating, and also because the Inuy leaves a
physical impression on the body (it makes the person weak). (The CHELKAS
YOAV OC #30 gives a similar differentiation.) Support can be brought to this
from TOSFOS in Nazir (28b, DH B'no) who suggests that while the Mitzvah of
Chinuch applies only to a Mitzvah of "Kum v'Aseh," it nevertheless applies
to Inuy on Yom Kipur because Inuy is a Mitzvah that is fulfilled actively,
through "Kum v'Aseh."
Rebbi Akiva Eiger and the K'sav Sofer suggest further that perhaps once the
verse teaches that a woman is obligated in Tosefes Inuy, we could learn from
there that a woman is obligated in all Mitzvos Aseh that are performed
passively, through "Shev v'Al Ta'aseh."
Perhaps we may bring another proof that women are exempt from passive
Mitzvos Aseh. The Gemara her derives from the Mitzvah of "Mora Av v'Em"
(fearing one's parents) that women are obligated to observe Mitzvos Aseh
*she'Ein* ha'Zeman Gerama. Mora, showing fear, is a passive Mitzvah (as we
see from the Gemara at the end of 31b), and nevertheless women are obligated
only because it is a Mitzvah *she'Ein* ha'Zeman Gerama. This implies that
women are indeed exempt from a passive Mitzvah that is limited to a certain
time. The Acharonim, however, do not mention this Gemara as a proof. Perhaps
they consider "Mora" to be an active Mitzvah (for example, one who is
sitting in her father's seat is obligated to get out of the seat).
Although the K'sav Sofer shows that TOSFOS in Kesuvos (47a, DH d'Masar)
seems to imply that women *are* obligated in Tosefes Yom Tov, implying that
he holds that women are obligated in Mitzvos Aseh that are done passively,
nevertheless he and the other Acharonim prove that many Rishonim clearly
reject this logic and equate all Mitzvos Aseh, whether they are done
passively or actively. This is the opinion of TOSFOS here (DH Ma'akeh) who
writes that women are exempt from the Mitzvas Aseh of Shevisah on Yom Tov,
and they are only obligated in the Lo Ta'aseh. This is also the view of the
RAMBAN, RITVA, and RAN, who write that women would have been exempt from the
Mitzvas Aseh of Shevisas Yom Tov had it not been associated with a Lo
Ta'aseh.
(The questioner who asked Rebbi Akiva Eiger about this apparently suggested
that the "Yesh Mefarshim" cited by Tosfos might argue with Tosfos regarding
this point. The "Yesh Mefarshim" holds that women are obligated in passive
Mitzvos Aseh, and that is how the "Yesh Mefarshim" would answer the question
that Tosfos asks on their opinion. This might also be the opinion of Tosfos
in Kesuvos cited by the K'sav Sofer.)
Hence, according to most Rishonim, women should be exempt from the Inuyim
(other than eating and drinking) on Yom Kipur, and from Tosefes Yom Tov (and
from the Mitzvos Aseh of Shevisas Behemah v'Avadim on Yom Tov).
