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!

Key words: Incongruity, playfulness, mindfulness, trickster, craftsman, poet, glitches.

Robert Stecker has posed a dilemma for the constructivist theory of interpretation: either interpretations consist of statements with truth values or they do not. Stecker argues that either way, they cannot change the meaning of an artwork. In this article, I argue contra Stecker that if interpretations consist of meaning declarations rather than statements, they can change the meanings of the objects toward which they are directed, where whether they so consist is largely a function of the interpreter’s intentions. Hence, the second horn of Stecker’s dilemma is defeated.

Living systems are characterized as self-generating and self-maintaining systems. This type of characterization allows integration of a wide variety of detailed knowledge in biology. The paper clarifies general notions such as processes, systems, and interactions. Basic properties of self-generating systems, i.e. systems which produce their own parts and hence themselves, are discussed and exemplified. This makes possible a clear distinction between living beings and ordinary machines. Stronger conditions are summarized under the concept of self-maintenance as an almost unique character of living systems. Finally, we discuss the far-reaching consequences that the principles of self-generation and self-maintenance have for the organization, structure, function, and evolution of singleand multi-cellular organisms.

Recognising and representing one’s self as distinct from others is a fundamental component of self-awareness. However, current theories of self-recognition are not embedded within global theories of cortical function and therefore fail to provide a compelling explanation of how the self is processed. We present a theoretical account of the neural and computational basis of self-recognition that is embedded within the free-energy account of cortical function. In this account one’s body is processed in a Bayesian manner as the most likely to be “me”. Such probabilistic representation arises through the integration of information from hierarchically organised unimodal systems in higher-level multimodal areas. This information takes the form of bottom-up “surprise” signals from unimodal sensory systems that are explained away by top-down processes that minimise the level of surprise across the brain. We present evidence that this theoretical perspective may account for the findings of psychological and neuroimaging investigations into self-recognition and particularly evidence that representations of the self are malleable, rather than fixed as previous accounts of self-recognition might suggest.

Excerpt: As a young man worrying about the fundamental questions of philosophy, metaphysics, and epistemology, McCulloch set himself the goal of developing an “experimental epistemology”: how can one really understand the mind in terms of the brain? More particularly, he sought to discover “A Logical Calculus Immanent in Nervous Activity.” The present paper will seek to provide some sense of McCulloch’s search for the logic of the nervous system, but will also show that his papers contain contributions to experimental epistemology which provide great insight into the mechanisms of nervous system function without fitting into the mold of a logical calculus. Moreover, McCulloch was not only a scientist but also a storyteller, poet, and memorable “character. ” I will thus interleave a number of characteristic anecdotes into the more objective attempts at scientific history that follow.

Constructive theories of brain function such as predictive coding posit that prior knowledge affects our experience of the world quickly and directly. However, it is yet unknown how swiftly prior knowledge impacts the neural processes giving rise to conscious experience. Here we used an experimental paradigm where prior knowledge augmented perception and measured the timing of this effect with magnetoencephalography (MEG). By correlating the perceptual benefits of prior knowledge with the MEG activity, we found that prior knowledge took effect in the time-window 80–95ms after stimulus onset, thus reflecting an early influence on conscious perception. The sources of this effect were localized to occipital and posterior parietal regions. These results are in line with the predictive coding framework.

Compared with traditional theories, systems theory presents a deviation. It replaces causal explanation by functional explanation. This paper shows what scandalon is inherent in this substitution and elucidates some models (self-organization, dance, non-triviality, structural coupling) which put the explanatory principle to work. The paper concludes by showing how systems theory aims at a general concept of communication that not only means a passing on of knowledge but above all the tracing of ignorance. Overall, systems theory is presented as a joker dealing with the paradox that the system is never identical to itself as soon as it is considered as a function of itself and its environment. The system has to withdraw into the function it is a function of in order to enfold this paradox.

Intuition suggests that perception follows sensation and therefore bodily feelings originate in the body. However, recent evidence goes against this logic: interoceptive experience may largely reflect limbic predictions about the expected state of the body that are constrained by ascending visceral sensations. In this Opinion article, we introduce the Embodied Predictive Interoception Coding model, which integrates an anatomical model of corticocortical connections with Bayesian active inference principles, to propose that agranular visceromotor cortices contribute to interoception by issuing interoceptive predictions. We then discuss how disruptions in interoceptive predictions could function as a common vulnerability for mental and physical illness.

Context: The enactivist tradition, out of which neurophenomenology arose, rejects various internalisms – including the representationalist and information-processing metaphors – but remains wedded to one further internalism: the claim that the structure of perceptual experience is directly, constitutively linked only to internal, brain-based dynamics. Problem: I aim to reject this internalism and defend an alternative analysis. Method: The paper presents a direct-realist, externalist, sensorimotor account of perceptual experience. It uses the concept of counterfactual meaningful action to defend this view against various objections. Results: This account of experience matches certain first-person features of experience better than an internalist account could. It is fully tractable as “normal science.” Implications: The neuroscientific conception of brain function should change from that of internal representation or modelling to that of enabling meaningful, embodied action in ways that constitutively involve the world. Neurophenomenology should aim to match the structure of first-person experience with the structure of meaningful agent-world interactions, not with that of brain dynamics. Constructivist content: The sensorimotor approach shows us what external objects are, such that we may enact them, and what experience is, such that it may present us with those enacted objects.

The aim of this paper is to present synthetically the central concepts and fundamental laws of Niklas Luhmann’s “Theory of Autopoietic Social Systems” and “Theory of Functional Social-Autopoietic Systems.” To do this we outline the conceptualization of notions like time, communications, observations, elements, relationships, complexity, connection, operation, environment, function, code, program, generalized symbolic media and their interrelationships and place within the laws of the theory. The guiding questions of this paper are: What entities do Luhmannian theory tell us about? How do these entities behave within the laws of the theory? And finally, the practical evaluation over the aims and goals of Luhmann’s theoretical program:, for which purposes? Relevance: The document presents, in a clear way, the central concepts of Luhmann’s theory of autopoiesis and its relevance to the study of social phenomena.
