Jewish Legal Reasoning and Responsa
Method
This domain tests pilpul (analytical reasoning), precedent, and the application of halachic sources. Know the hierarchy: Torah she-bichtav, Torah she-ba'al peh, Gemara, Rishonim, Acharonim, and responsa. Understand kal vachomer, gezerah shavah, and binyan av as hermeneutical rules.
Responsa
Master the structure of a responsum: the question, the sources cited, the reasoning, and the conclusion. Know how posekim weigh conflicting authorities and the role of minhag (custom).
Traps
- Treating a minority opinion as normative without justification.
- Ignoring the distinction between lechatchilah and bedi'eved.
- Misapplying a gezerah shavah without the traditional transmission.
- Confusing takkanot (rabbinic enactments) with d'oraita law.
Worked example
A question asks whether a certain practice is permitted. The answer should: (1) identify the relevant sources, (2) note conflicting opinions, (3) apply the rules of pesak (e.g., majority, precedent), and (4) state the practical conclusion with lechatchilah/bedi'eved distinctions.
