Piaget defines intelligence as adaptation, or the ability to maintain a balance between stability and change, or, in his own words, between assimilation and accommodation. When people assimilate the world to their current knowledge, they impose their order upon things. This momentary closure is useful to build “invariants” that lend existence to the world, independent of immediate interaction. In accommodation, people become one with the object of attention. This may lead to momentary loss of control, since fusion loosens boundaries, but allows for change. I choose the domain of perspective-taking to illustrate how this alternation between assimilation and accommodation punctuate individuals’ interactions with the world. I show that the ability to move away from one’s own standpoint, and to take on another person’s view, requires the construction of cognitive invariants: a recasting of the world’s stabilities that transcends any given viewpoint. I conclude that separation is a necessary step toward the construction of a deeper understanding, and that adopting a “god’s eyes view” is by no means contrary to situating one’s one stance in the world.

An important tenet of constructivism is that learning is an idiosyncratic, active and evolving process. Active learning, operationalized by cognitive, metacognitive, affective and resource management learning strategies, is necessary for students to effectively cope with the high level of demands placed on the learner in a constructivist learning environment. Case studies of two students detail contrasting passive and active learning behaviours. Examples of their strategic learning behaviours illustrate that having students involved in activities such as discussions, question answering, and seatwork problems does not automatically guarantee successful knowledge construction. The nature of students’ metacognitive knowledge and the quality of their learning strategies are seen to be critical factors in successful learning outcomes.

It is characteristic of Heinz von Foerster’s approach to the cybernetics of cybernetics that it combines a sense of tight reasoning with the acknowledgment of fundamental ignorance. The article attempts to uncover an epistemological relationship between the reasoning and the ignorance. The relationship is provided for by a razor which reads: what can be described in relation to its composition, is described in vain in relation to its substance. The razor asks for second-order terms instead of first-order terms, or for ontogenetics instead of ontology.

How may mental activity be conceptualized within the context of the epistemology engendered by cybernetics, and how may that epistemology account for imagination? I argue for an epistemology of imagination that both distinguishes imagination, understanding and interpretation, and unites all three concepts in a dialogical circle of ideas. The processes of distinguishing these concepts (and the processes that give rise to and describe mental activities) are dialogical processes. As dialogical, they fall within the scope of Heinz von Foerster’s work on second-order cybernetics.

Ralph Gehrke’s critique of an empirical study of literature reveals misunderstandings and implications which first need to be questioned. The discussion in this paper focuses an the following aspects: the constitution of the domain of literary scholarship, of concepts of literature, methods of analyzing, and questions of the self-definition of literary scholars in a media-dominated era.

This article praises the development of second-order cybernetics by von Foerster, Maturana and Varela as an important step in deepening our understanding of the biopsychological foundation of the dynamics of cognition and communication. Luhmann’s development of the theory into the realm of social communication is seen as a necessary and important move. The differentiation between biological, psychological and socialcommunicative autopoiesis and the introduction of a technical concept of meaning is central. Furthermore, Varela’s development of Spencer Brown’s ‘Laws of Form’ from a dual to a triadic categorical basic structure is considered vital. Finally the paper shows that second-order cybernetics lacks explicit and ontological concepts of emotion, meaning and a concept of signs. C. S. Peirce’s theory is introduced for this purpose. It is then shown that both theories are triadic and second order, and therefore can be fruitfully fused to a cybersemiotics.

Mancuso’s (1996) article is to be welcomed for its attempt to bring together social constructionism, personal construct theory and narrative psychology. Whilst the underlying tendency of the three approaches-to view the text as self-enclosed and constitutive of reality-is drawn out well, the differences between them are underplayed. Most significantly, these include the difference between the individualist ontology in Mancuso’s version of personal construct theory and the social ontology that is the basis of social constructionism. The fact that Mancuso ignores these differences in ontology ultimately thwarts his commendable aim of reintroducing issues of individual psychology into a constructionist framework.

This article investigates the following basic question: in the relatively stable molecular environment of a vertebrate body, can a dynamic idiotypic immune network develop a natural tolerance to endogenous components? Our approach is based on stability analysis and computer simulation using a model that takes into account the dynamics of two agents of the immune system, namely, B-lymphocytes and antibodies. We investigate the behavior of simple immune networks in interaction with an Ag whose concentration is being held constant as a function of the connectivity matrix of the network. The latter is characterized by the total number of clones, N, and the number of clones, C, with which each clone interacts. The idiotypic network models typically become unstable in the presence of this type of Ag. We show that idiotypic networks that can be found in particular connected regions of NC-space show tolerance towards auto-Ag without the need for ad hoc mechanisms that prevent an immune response. These tolerant network structures provide dynamical regimes in which the clone which interacts with the auto-Ag is suppressed instead of being excited such that an unbounded immune response does not occur. Possible implications for the future treatment of auto-immune disease such as IvIg-treatment are discussed in the light of these results. Moreover, we propose an experimental approach to verify the results of the present theoretical study.
