Pesachim 002: Insights, Regarding Machlokes Rashi vs. Tosfos about Bitul
 
Yisrael asked:
 
May I ask the name of one of the Acharonim you refer to in Insights to the Daf, 
Pesachim 2a. 
 
In your words: "The Acharonim point out that Rashi and Tosfos seem to disagree 
about the fundamental mechanism of how Bitul works. Tosfos does not suggest the 
answers that the Ran and others give for Rashi, because he understands that 
Bitul is a form of Kinyan. That is, through Bitul, one makes the Chametz 
ownerless (Hefker). Therefore, Tosfos maintains that there is no concern that 
after one does Bitul, he might find Chametz on Pesach, wait some time before he 
destroys it, and thereby transgress Bal Yera'eh and Bal Yimatzei (as in (b) 
above). Even if he does wait and does not burn it immediately, it is still 
Hefker, because his Bitul effected an actual Kinyan that rendered the Chametz 
ownerless. The former owner does not acquire the Chametz again merely by 
looking at it and wanting it. Similarly, if one verbally proclaims his Bitul, 
but he does not whole-heartedly want to make it ownerless, the Chametz 
nevertheless becomes irrevocably Hefker (as opposed to the logic mentioned in 
(c) above). It is the verbal proclamation that is effective when one makes a 
Kinyan, and not the thoughts in one's heart (Gitin 38a)."

The Kollel replies:
 
Kehilos Yakov Pesachim 1:1, Devar Shmuel Pesachim 2a. (The words and 
presentation are our own, but the basic idea appears in those Sefarim.)
 
Best wishes,
Mordecai Kornfeld
