Query: POR

I have purchased and read this book. In my opinion the very title was relished!: Why must there always be a reason for something? and on/in what grounds does the principle of reason lie? Indeed for anything whatsoever? "Why the why?" Cool subject for me! My 4 year old copy is dog-eared and scribbled on. Those who have purchased this book surely will agree when I say that there are a great many gleanings to be had from this digestible and erudite work. A very satisifying book.
