Some time ago, following a request from the journal of the Porto Alegre Psychoanalytical Society to write a commentary on ‘Evidence’ (Bion 1976), which I had not looked at for many years, I reread this contribution and was surprised to discover in it the Bion of whom I am fondest. In just a few highly condensed pages, he once again sets out the central themes of his thought and sows an abundance of seeds for possible future reflections.
