Chazal suggest that this question is asked by the “wise” son of the “four” sons of the Haggadah. We are taught that the Torah “speaks” to each of the four sons, representing four perspectives or types of Jews. Each one has his own focus, each one has his own perspective, analogous with his chosen way of life. What is the distinction of having four sons? It would seem that Chazal are lauding the fact that these “four sons” truly exist.
Horav Chaim Soloveitchik, zl, distinguishes between secular studies — in which the text is divided according to one’s age or level of skill and aptitude – and Torah studies. As one progresses in his knowledge and ability, the text changes and a more challenging, definitive text is used. Torah is different. The same text, the same Torah, the identical Chumash and Rashi studied by the young child will also be used by the Torah scholar. Each person will delve into the same material. In accordance with his level of erudition, each will discover profundities unknown and unattainable to one of lesser ability and knowledge. “Blessed be Hashem, blessed be Him,” corresponding to four sons the Torah speaks. The same Torah is studied by various levels of students, each one according to his individual level of learning.
