From Maria Popova in Brain Pickings…
…Indeed, this notion of “surprised amusement” becomes central to Bruner’s conception of creativity, which he defines with succinct elegance:
An act that produces effective surprise [is] the hallmark of the creative enterprise.
…It is essential, here to distinguish between creativity and originality. In a sentiment that brings to mind Twain’s famous assertion that plagiarism is the seed of creative work, Alexander Graham Bell’s conviction that “our most original compositions are composed exclusively of expressions derived from others,” and Henry Miller’s poetic debunking of the originality illusion, Bruner cautions:
The road to banality is paved with creative intentions. Surprise is not easily defined. It is the unexpected that strikes one with wonder or astonishment. What is curious about effective surprise is that it need not be rare or infrequent or bizarre and is often none of these things. Effective surprises … seem rather to have the quality of obviousness about them when they occur, producing a shock of recognition following which there is no longer astonishment….
…Metaphorical effectiveness is also manifested by “connecting domains of experience that were before apart,” but what distinguishes it from the formal kind is that the mechanisms of connectedness come for the realm of art rather than science and logic — the kind of connectedness that Carl Jung described as “visionary,” in contrast to the merely psychological. (Metaphorical thinking, after all, is at the developmental root of human imagination.) While we are wired to make sense of the world via categorization, “metaphoric combination leaps beyond systematic placement, explores connections that before were unsuspected.”
