Kinyan 45 Lomed Al Minas La'asos - Between The Pnei Yehoshua & Rav Yehonoson Eibushitz
The greatest adversary of Rav Yehonoson Eibushitz aside from Rav Yaakov Emden was Rav Yaakov Yehoshua of Frankfurt, also known as the Pnei Yehoshua.  Rav Yehonoson Eibushitz was famous for his dazzling Drashos while the Pnei Yehoshua was known as a brilliant posek.  The talmidim of the two would compete with each other each claiming their Rosh Yeshiva to be far superior.  "He can say nice Drashos but Rav Yehonoson Eibushitz doesn't compare to the Pnei Yehoshua in Psak Halacha" the talmidim of the Pnei Yehoshua would taunt.  In response Rav Yehonoson Eibushitz's talmidim would say that other than knowing psak halacha the Pnei Yehoshua doesn't come close to being the lamdan that Rav Yehonoson Eibushitz is.

Lo and behold The Pnei Yehoshua then went on to print his sefer considered one of the deepest and most Lomdishe Seforim on Shas, while Rav Yehonoson EIbushitz produced two of the most heralded seforim on Choshen Mishpat and Yoreh Dei'a, the Urim V'Tumim and Kreisi U'Pleisi (Mishel HaAvos).  At the highest level lamdus and l'ma'aseh are one and the same.

It is said that Aristotle was quite an unruly man whose behavior did not speak well for one of the greatest intellectuals the world has ever seen.   When asked how a man of his stature can behave the way he does despite his teachings he basically said that just because he is so smart it shouldn't mean that he cannot have a good time.  

Torah is not strictly an intellectual exercise best left in the halls of academia.  It is alive and it is meant to help us conduct ourselves in this L'Ma'aseh world.  It is a blueprint for our lives and that is how we must learn it.  To do so requires depth and breadth but without ever losing sight of the L'Maaseh.
