Too what extent can we reasonably read in slow motion while tendering to our other undergrad learning needs as well?

I am very excited and intrigued by Miller’s teaching philosophy, but it certainly raises a lot of applicability questions.  It seems like there are myriad positives to reading only one text for a class, allowing for the expansion of thought into other possibilities, trying to inspire excitement and movement to action in students.  But this pedagogical philosophy can’t be applied to all classes can it?  How would we ever learn enough in four years of classes like this?  Also, do you think that this kind of class could be taught in other disciplines as well as the humanities?  How would this work for a science class or a math class?  Maybe it can’t?

So I guess my main questions are, is this teaching philosophy applicable outside of say, having only one or two classes like this in four years of undergrad study?  And if it is not, if it cannot be applied to several or all classes, then how do we choose what one class would work best under this methodology?
