ABSTRACT
Professor von Wright’s contribution to the Helsinki Entretiens on theory of knowledge (von Wright 1972b) was a particularly lucid presentation of the main ideas of a difficult work of Wittgenstein’s when it was as yet unfamiliar. He advanced interesting suggestions regarding the application and scope of those ideas. If I dwell first on some parallels (to which he has drawn attention) with Wittgenstein’s earlier work, the Tractatus, I hope it will become apparent that this is not wholly due to my own preoccupations but has an important bearing on the subject of the Entretiens.
