Journalism, journal, journey--from the reviews he wrote for The New Youk Times between 1961 and 1964 and longer articles (for Art and Artists, Newsweek, etc) since, Brian O'Doherty has compiled a record of telescoping trends and emerging, shifting reputations which is also what he wanted it to be, a flow of response. Eschewing ""a set theory of criticism"" and ""pure value judgments,"" risking inconsistency, he has taken the next step and recognized that ""some new works demand new standards, which those works implicitly offer."" What saves even the occasional criticism from quick obsolescence (beyond his skill in transmuting visual impressions into verbal evocations) is his success in defining the new standards implied by Abstract Impressionism, Op, Pop, Ob--each depending on relationship, each requiring the participation of the observer. Part One is theme and statement, Part Two takes up significant artists in the mainstream, those outside (including Evergood, Bloom and Wyeth), and current controversials (Marisol, Stella, Rauschenberg, etc.). Several he interviewed, some he knew, and their personalities add an edge to the comments. In the last section we are very much on The Scene with museums and collectors. The absence of illustrations is probably intentional; this is not a historical survey or another course in appreciation but appreciative discussion of what the reader has presumably seen and puzzled over, as well as a formulation of principles for those on the fringes of the art process.
