The problem with Armstrong's little biography of Buddha is that the Buddha has no biography -- that's the whole point of being a Buddha. There are fragments of biographical material on Siddhartha Gotama, of course, & quite a lot of historical & cultural information about his place & time. That's what Armstrong uses to write her "biography" of Buddha & though she lays this all out in her Introduction, she never really seems to understand the difference. But the more basic problems with the book are these: 1. Armstrong appears to have the sort of knowledge of Buddhism you'd get from taking a couple of undergraduate classes; 2. she has a thesis about the Axial Age that assumes a kind of religious universalism & that universalism pretty much has to erase Buddhism (& Christianity & Islam &†Judaism†& etc.) There is not much mention of the fact that Buddhism is the one non-theistic religious tradition to have emerged in the first century BCE. Not a very useful book for Buddhists because Armstrong doesn't seem to "get" Buddhism & probably not very useful for non-Buddhists because the version of Buddhism presented here is filtered through the screen of a universalist ideology.
