Each time John O'Loughlin writes a new book it is as though it were the literary equivalent of a music CD, with a number of titles that, by and large, are independent of each other and encourage the reader to proceed from one subject to another in what is almost invariably a cyclical progression, thereby achieving a degree of metaphysical credibility. In this particular project there are some twenty cycles, all of which are self-sufficient and yet also interrelated in what becomes a bigger picture of an overall philosophy stretching ever further onwards in the quest for ultimate truth and, hence, metaphysical perfection. We needn't elaborate on any of the subjects here, because most of them will have been explored to some extent in the author's work before; but we doubt whether he has ever written or, rather, composed, methodically and meticulously, anything better up till now, least of all in relation to the complex philosophical and moral problems posed by the distinction of 'right' and 'wrong', which here undergoes what we believe to be a morally definitive presentation.
