In the late 90s, I spent quite a bit of time arguing Philosophy online. After many hours of answering objections and addressing problems in the Alt.Philosophy newsgroup, I came to see that my posts were relatively consistent, and could work as a series of "interviews". The collection covers subtle and very fundamental philosophical and scientific topics and problems, and includes an oft-quoted refutation of Ayn Rand's pseudo-rational "objectivism". The refutation has never been rationally countered by any objectivist.
