Why Beit Hillel's Rulings Govern Jewish Law
These sources explain the talmudic principle that halachic decisions follow Beit Hillel over Beit Shammai, grounding this choice in their humility and deference to others, the preservation of dissenting views for future application, and the kabbalistic understanding that chesed (lovingkindness) forms the governing framework of divine and human conduct. They also consider how practical law must serve the majority rather than exceptional cases.

The Maharal on Written and Oral Torah
The Maharal of Prague presents the Written and Oral Torah as divinely complementary modes of wisdom transmission.
