Enjoyed reading this article.While I agree that Judaism is a wordly religion, I think that it is important to note that rabbinic literature is full of examples of tension that existed between emphasis on study and on deeds of loving-kindness (g’milut chasadim).  For example:    

A. In Kiddushin we read: “Which is greater—study or deeds? Rabbi Tarfon answered, ‘Deeds!’ Rabbi Akiva answered, ‘Study!’ The sages responded, ‘Study is greater since studying leads to deeds’ (b. Kiddushin 40b).

B. “These are things that a person enjoys the fruits of in this world while the principal remains for the world to come: honoring one’s mother and father, g’milut chasadim, and being a peace maker. But Talmud Torah is equal to them all” (m. Peah1:1). 

C. “He who engages exclusively in Talmud Torah is as one who has no God” (b. Avodah Zarah17b).
