That is the new book by John S. Strong, which I recommend highly. It won’t charm you or interest you in the subject if you don’t already care, but the already-motivated can learn a great deal from it.
I find most books on Buddhism frustrating. One you know the basics, they just feed you the same blah blah blah, running your mind in empty circles. But perhaps Buddhism is like macroeconomics — you can’t understand it until you know what people argue about, and that is what John S. Strong clues us in on. Here is one typical summary passage:
We have, in this chapter, sought to explore various iterations of the Middle Way, a notion which the Buddha sets forth at the start of his First Sermon. In order to unravel the many implications of this principle and its applicability to other Buddhist doctrines (something the Buddha did not do in his sermon), I have presented several of its expressions and sought to set them within the context of various philosophical and religious movements that may have been around at the time of the Buddha. Thus, early Buddhists can be seen as finding their way between karma-deniers and karmic absolutists; and as combining views of saṃsāra both as a real material trap and as an illusory trap; and as shying away from the extremes of affirmation of an Absolute Self and denial of personal continuity. The Middle Way, however, is not the only thing set forth in the First Sermon as we have it, a text which is mostly devoted to the doctrine of the Four Truths, to which we shall now turn.
Another good way to read about Buddhism is to look at up through p.59 in Nicholas Ostler’s Passwords to Paradise: How Languages Have Re-Invented World Religions. It covers the differential historical spread of Buddhism through the languages of Pali, Gandhari, Sanskrit, and Chinese. Ostler himself claims to have a working knowledge of eighteen different languages.
