Imagine a book with three Chapters,the subject of each chapter is a complete up to the moment understanding Chemistry. That's right if one diligently studies any of the three chapters of our hypothetical book he would become an expert on the subject of chemistry. Also having studied any of the three chapters none of the remaining chapters could contribute any further understanding of the aforesaid subject to our reader .
Let's say that this book alone contained this up to the moment understanding of chemistry.
If all of these premises be accepted as true, how could the claim that that any particular chapter of this book is necessary re: a complete understanding of chemistry be taken seriously?
Would this book in its entirety be any more valuable re: an up to the moment knowledge of chemistry than any of its chapters?
Would any worthwhile refutation be possible of the observation that this book is a couple of chapters too long?
