Placher has done a wonderful job of delivering on a whole host of ideas. He has made some very complicated ideas much more accessible than many authors. He writes in a captivating way that is almost like reading a story than a textbook presenting ideas.
From the influence of Greek philosophy to the "End of Christendom", he touches on many key ideas in a way that makes you want to read more. He is clear and at times puts in a bit of his own opinion in an educated manner.
This is still just an introduction, since you cannot be comprehansive in so few pages. But he brilliantly solves this problem by giving a very good bibliography at the end of each chapter. Moreover, he has a basic and advanced bibliography for each which helps you decide how "deep" you want to get into a subject. It is unfortuante that some of the books are out of date.
I highly recommend this for any theological student.
