Torah scholar who study only Talmud, and whose entire activity consists of pilpul (casuistry) and do not attend to also studying laws, are in error. For the purpose of studying Talmud is to learn the required laws, and to teach God's laws. The purpose of study is to act or to teach, and one must allocate time to learning and considering the responsa of adjudicators, to know how to teach and how to act. One should set regular times for the study of Shulchan Aruch and its supplements to attain proficiency in knowing the laws, those that are currently applicable, in particular. For we see, to our chagrin, that some Torah scholars are extremely studious and precise, yet when confronted with questions of simple laws that are clarified in the Shulchan Aruch, even those laws of prayer and the recitation of blessings, do not know how to reply. They end up making secondary matters primary. For pilpul and cleverness were not created for their own sake, but to teach law. They serve to sharpen the mind so that it be prepared to learn rulings, questions and answers, and to teach God's law and teachings, and to avoid errors when teaching.
