(ב) אֵין הוֹלְכִים בְּפִקּוּחַ נֶפֶשׁ אַחַר הָרֹב. אֲפִלּוּ הָיוּ תִּשְׁעָה עַכּוּ''ם וְיִשְׂרָאֵל אֶחָד בְּחָצֵר, וּפֵרַשׁ אֶחָד מֵהֶם לְחָצֵר אַחֶרֶת וְנָפְלָה עָלָיו שָׁם מַפֹּלֶת, מְפַקְּחִין, כֵּיוָן שֶׁנִּשְׁאַר קְבִיעוּת הָרִאשׁוֹן בִּמְקוֹמוֹ חַשְׁבֵינָן לֵיהּ כְּמֶחֱצָה עַל מֶחֱצָה. אֲבָל אִם נֶעֶקְרוּ כֻּלָּם וּבִשְׁעַת עֲקִירָתָן פֵּרַשׁ אֶחָד מָהֵם לְחָצֵר אַחֶרֶת וְנָפַל עָלָיו, אֵין מְפַקְּחִין עָלָיו; שֶׁכֵּיוָן שֶׁנֶּעֱקַר קְבִיעוּת הָרִאשׁוֹן מִמְּקוֹמוֹ, אַמְרִינָן: כָּל דְּפָרִישׁ מֵרֻבָּא פָּרִישׁ.
(85) Although the prohibition concerning wounding does not apply in these limited situations, is it permissible to place one's life in danger in order to alleviate psychological anguish? Citing the above-mentioned comments of Rema, Rabbi Breish argues that even the amputation of a limb is permissible in order to alleviate pain. The Gemara, in a number of instances (Shabbat 129b, Avodah Zarah 30b, Niddah 31a and Yevamot 72a), indicates that a person may engage in commonplace activities even though he places himself in a position of danger in so doing. In justifying such conduct the Gemara declares, "Since many have trodden thereon 'the Lord preserveth the simple' (Ps. 116:6)." The talmudic principle is that man is justified in placing his trust in God, provided that the risk involved is of a type which is commonly accepted as a reasonable one by society at large. Rabbi Breish apparently feels that any accepted therapeutic procedure falls into this category.16cCf. Darkei Teshuvah, Yoreh De‘ah 155:2; Levushei Mordekhai, Yoreh De‘ah, II, no. 87; and R.
