Rabbi Baruch Bodenheim: Gemara Shabbos: Perek Kirah: Muktza יום רביעי Sivan 11 דף מד.- מיגו דאתקצאי (05/27/26)

Sugya – מיגו דאתקצאי

There is a major machlokes between ר”י & ר”ש if a lantern that was lit at the begining of Shabbos remains Muktzah for the entire Shabbos even after the flame is extinguished. 

This machlokes is contingent on the concept of מיגו דאתקצאי – something which is Muktza during Bein Hashmoshas remains Muktza for the entire Shabbos.

Major Question:

What is the reasoning of מיגו דאתקצאי?

Review the אפיקי ים חלק ב ס’ יט – first two paragraphs.

Why does ר”ש not hold of – מיגו דאתקצאי?

What is the explanation for their argument?

Question:

Based on what we learnt from the אפיקי ים and the Chazon Ish how can we explain the logic that only when there is a combination of מוקצה מחמת איסור and מוקצה מחמת מיאוס will we say מיגו דאתקצאי
