Opposition
Many leading rabbinic authorities have harshly criticized this method as being unreliable and a waste of time, and it is regarded by some as having been discredited by the time of the Vilna Gaon. A common criticism is that those who used this method were often motivated by the prospect of impressing others with the sophistication of their analysis, rather than by a disinterested pursuit of truth; such students, it was held, did not apply appropriate standards of proof in obtaining their conclusions (if any), and frequently presupposed conclusions that necessitated unlikely readings (interpretations) of "proof-texts". As such, pilpul has been derogatorily called bilbul, Hebrew for "confusion".[8]
Judah Loew ben Bezalel (the Maharal), in a famous polemic against pilpul, wrote:
It would be better to learn carpentry or another trade, or to sharpen the mind by playing chess. At least they would not engage in falsehood, which then spills over from theory and into practice..."[9]
The Rebbe Sholom Dovber Schneersohn, quoting Maharal, allows for "genuine pilpul" while dismissing "false pilpul":
Genuine pilpul is possible only when first one knows the simple meaning of the Halachah guilelessly, in a structured manner, using straightforward terms... Afterwards, if G‑d has graciously endowed a person with a capable intellectual potential and broad-minded thought processes, he may delve into a pilpul.... If, however, a student will begin with pilpul before he has a genuine appreciation of the subject in the above manner, as a natural consequence, the pilpul will be false, and he will waste his time with ersatz thoughts.[10]
An approach contrasting to pilpul, often referred to as "aliba dehilchasa [he]" ("analyzing the sugya re. the Halacha"), emphasizes (legal) application over abstraction.
