John O'Loughlin has consistently advanced the theoretical breadth and depth of his work, derived, naturally, from habitual thought processes, and the results should speak confidently and credibly enough for themselves without our having to say very much about them, other, of course, than that they continue in the vein to which we have become accustomed over the years the author's struggle for truth, or philosophical credibility and metaphysical insight, and have continued the process to a new and hopefully final level or stage of completion which it would be difficult if not impossible for him or, for that matter, anyone else to reasonably surpass, bearing in mind the complexities that so exactingly comprehensive an approach to logic as he has fathered both here and in the past inevitably entail.
