John O’Loughlin’s first exercise in philosophy, originally dating from 1977, takes as its starting-point an analysis of the interrelativity of dualities and expands, via a series of aphoristic essays and dramatic lessons, towards a dialogue climax in which the two – inevitably! – characters discuss the implications of a dualistic philosophy both as it impacts on theory and practice. Although the author didn’t realize it at the time, truth and illusion are a lot closer together than may at first appear to be the case, even if one doesn’t necessarily have to get between them to discover this! Interestingly, there are also a few quadruplicities, or fourfold structures, in this early text which could be seen as intimating, from some distance, of the author’s later philosophy as it emerges from dualism without ever abandoning its original starting-point.
