Context: The idea for this article sprang from a desire to revive a conversation with the late Ernst von Glasersfeld on the heuristic function - and epistemological status - of forms of ideations that resist linguistic or empirical scrutiny. A close look into the uses of humor seemed a thread worth pursuing, albeit tenuous, to further explore some of the controversies surrounding the evocative power of the imaginal and other oblique forms of knowing characteristic of creative individuals. Problem: People generally respond to humor, i.e., they are inclined to smile at things they find funny. People like to crack jokes, make puns, and, starting at age two, human infants engage in pretense or fantasy play. Research on creativity, on the other hand, has mostly scorned the trickster within. Cognitivists in particular are quick to relegate wit, whimsy, and even playfulness to the ranks of artful or poetic frivolities. Method: We use the emblems of the craftsman, the trickster, and the poet to highlight some of the oblique ways of knowing by which creative thinkers bring forth new insights. Each epitomizes dimensions intrinsic to the art of “possibilizing.” Taken together, they help us better understand what it means to be playful beyond curious, rigorous beyond reasonable, and why this should matter, even to constructivists! Results: The musings characteristic of creative individuals (artists, scientists, children) speak to intelligent beings’ ability to use glitches intentionally or serendipitously as a means to open up possibilities; to hold on to a thought before spelling it out; and to resist treating words or images as conventional and arbitrary signs regardless of their evocative power. To fall into nominalism, Bachelard insisted, is a poet’s nightmare! Implications: Psyche is image, said Jung, and when we feel alive we rely on the imaginal to guide our reason. Note that image is not here to be understood as a picture in the head or a photographic snapshot of the world. The imaginal does not represent, it brings forth what we understand beyond words. It does not lock us into a single mode. Instead, it is a call to be mindful, in Ellen Langer’s sense: in the present, mentally alert, and on the outlook for our psyche’s own surprising wisdom (sagacity. Constructivist content: Debates on the heuristic function and epistemological status of oblique ways of knowing have long occupied constructivist scholars. I can only guess whether my uses of Jung’s imaginal or Bachelard’s anti-nominalism would have amused or exasperated Ernst! I do know that, on occasion, Ernst the connoisseur, bricoleur, and translator allowed the rationalist-within to include the poet’s power to evoke as a legitimate form of rationality. He himself has written about oblique knowing as legit!

Purpose: What is therapy? Which would be today Heinz von Foerster’s answer? The authors try to unveil the mystery of an answer coming from a conversation among them. They think that Heinz von Foerster, like Gregory Bateson, was one of the most influential philosopher of therapy. In the paper they analyse some very basic key words – like trivial machine, human becoming – and key concepts – like “broaden the field of possible” – in order to understand if there is an order or a purpose in doing therapy. Design/methodology/approach – The paper is a confrontation between epistemology and therapy. The trick is that, unlike von Foerster, the authors are therapists. So probably their conversation will not be reliable. But usually therapists, in doing therapy, do not look for reliability. They try to be accountable, which is a different issue. Findings: Probably therapy is a language game. If yes, the language game of therapy is a trick without a trickster. A map in a stranger land. That can be considered the main finding which follows from von Foerster’s thought. Practical implications: Nevertheless, such a wrong map sometimes could help who is lost, provided that map and territory will never be the same thing. Originality/value – The original value of the paper is, first of all that it can be considered the last essay written by Gianfranco Cecchin before his death. In the very last period of his life Cecchin was considering and sounding a new perspective for therapy. Pietro Barbetta and Dario Toffanetti were working with him in therapy and theoretically to find new frames for therapies in the post-modern era.

Key words: cybernetics, ethics.
