Query: brief

first, this book is quite brief. less than 200 pages, large font and margins. i can see why he is recognized as a distinguished professor at yale. he is brilliant and engaging. he covered all of the essential topics and this book is a sound, middle-of-the-road text. there were just a few statements he made that i re-re-read, asking myself, "did he really say THAT?" i wish that he had covered more topics and gone into greater depth on those that he did address. perhaps he has done so in other texts? overall, this is an excellent book that is somewhat interesting.
