Divided into three parts, of which the first is by far the longest, this philosophical sequel to 'Between Truth and Illusion' (1977), expands on the dualistic theories therein outlined, abandoning the more literary approach of its predecessor for a paradoxically aphoristic bias in which the author began to develop an almost existentialist awareness of the extent to which many so-called truths are founded upon illusory concepts and, to that extent, are not really 'true' at all but convenient fictions masking the brute reality of natural facts.
