Brother,
With the greatest respect your argument is flawed, as is your example,
Chemistry is a huge subject with many categories and sub categories, all lumped together under the name chemistry. If you were taking an exam, you would start at the start, and if the author of the book was worth his salt, he would lead you from the start to the finish and educate you on chemistry. He would begin with simple concepts that got harder and harder, but to understand the middle, or even the end of the book, you would find yourself needing to master and learn the start, for example, it is of no use opening the middle, if you do not even know what a mole is....
It is the same with maths, which is possibly a better example, embrace the concepts of X,Y,Z, and then move to algebra, equations, and by the end, you have the tools and the mental strength to decipher complex algebra equations as you are now familiar with the way these things work.
By your argument, one could find the answer on what happens when you burn Sodium by opening a chemistry book at random, and mentally asking the question, only a magic book could do that, and I resent the SGGS needing anything other than the information contained to justify its reverence
