any Torah without a foundation is not Torah

The Maharetz Chajes said, "The importance for a beginner in secular fields to have clear introduction is obvious, but it is even more important when studying Torah." He cites the Yerushalmi (Shabbos 87a): "any Torah without a foundation is not Torah." Says Maharetz Chajes, "That means Torah without an understanding of basic rules and concepts...." (Introduction to Toras Nev'im) 

"the approach of the study of hashkafa must take into careful consideration the specific needs, goals, and 'desires' of each individual in order to personally 'recognize the One who spoke and created the world."

"on a pedagogical level, the faith-study of the Torah is essentially the discerning and elaboration of the spectrum of ideas which defines the possibilities and boundaries of acceptable positions. A consequence of this is that the student must be exposed to a full spectrum of hashkafic thought in order to fully appreciate the issues and then formulate his own position."
