The most we can say of the function that is operative in the process of image-making or imagination is that it is a poetic function; and we define it best of all by calling it a function of play – the ‘ludic’ function in fact. In play as we conceive it the distinctions between belief and make-belief breaks down. The concept of play merges quite naturally with that of holiness. Any Prelude of Bach, any line of tragedy proves it.
