A KNOWLEDGEABLE APPROACH TO TRUTH is Volume One of John O'Loughlin's 'Collected Essays' and embraces material from five other titles, some in part, some in total, dating from 1977-81. The title is intended to be slightly tongue-in-cheek about approaching truth from such an egotistically if not egocentrically physical standpoint, but that is what the author was doing back in the late 1970s, at what was a comparatively early stage of his philosophical development, when he had yet to earn his aphoristic spurs or, rather, wings. - A Centretruths editorial.
