This paper presents a critical analysis of Tamar Szabó Gendler’s view of thought experiments, with the aim of developing further a constructivist epistemology of thought experiments in science. While the execution of a thought experiment cannot be reduced to standard forms of inductive and deductive inference, in the process of working though a thought experiment, a logical argument does emerge and take shape. Taking Gendler’s work as a point of departure, I argue that performing a thought experiment involves a process of self-interrogation, in which we are compelled to reflect on our pre-existing knowledge of the world. In doing so, we are forced to make judgments about what assumptions we see as relevant and how they apply to an imaginary scenario. This brings to light the extent to which certain forms of skill, beyond the ability to make valid logical inferences, are necessary to execute a thought experiment well.

Excerpt: I will take you on a tour through the idea of reality construction by travelling back and forth between the two intellectual strands in the process of modernization: the Enlightenment and Romanticism. The major part of our tour will be spent in the land of Romanticism, accepting without argument the kind of irrealism propounded by constructivists like Nelson Goodman, Richard Rorty and Jacques Derrida. But throughout I will try to give the Enlightenment its due by pointing out the important roles of technology in the processes of reality construction: in material constructions, as a basis for thought experiments, as provider of intellectual tools, and as a source for constructivist ideas in general.
Context: The detection of objective reality, truth, and lies are still heated topics in epistemology. When discussing these topics, philosophers often resort to certain thought experiments, engaging an important concept that can be broadly identified as “the global observer.” It relates to Putnam’s God’s Eye, Davidson’s Omniscient Interpreter, and the ultimate observer in quantum physics, among others. Problem: The article explores the notion of the global observer as the guarantor of the determinability and configuration of events in the world. It analyzes the consistency of the notion “global observer” from the standpoint of logic and philosophy, and discusses why application of this notion in some contexts poses challenges and appears to be paradoxical. Method: The paper uses conceptual methods of argumentation, such as logical (deduction) and philosophical (phenomenology) kinds of proof. Its key approach is the engagement of thought experiments. Results: The notion of a global observer is incoherent: “being global” and “being an observer” appear to be incompatible features. It is claimed that from the standpoint of global observation, there are no events occurring in the world. Furthermore, the indefiniteness of the world as a whole is asserted, which is related to the uninformedness of the global observer regarding the “true state of affairs.” “Global observation” turns out to be incompatible with the concept of the observer, blocking, as a result, the opportunity for a determinable configuration of events. It only makes sense to discuss local observations, which are limited to mutual observation or introspections, and not to assume the existence of some absolute truth, reality, or the state of affairs beyond the local observations. Constructivist content: The article emphasizes the role of the observer and observation. It opens up some problematic consequences of the core philosophical assumptions of globally observing existence. Referring to von Foerster’s and Luhmann’s idea that we can only speak reasonably about local observations, the paper argues that reality is neither external to nor independent of the observer. Implications: The paper could be productive for epistemic theories, theories of quantum physics, and theories of non-classical logic.
Gasparyan D. (2020) Semiosis as Eigenform and Observation as Recursive Interpretation. Constructivist Foundations 15(3): 271–279. https://cepa.info/6608
Context: Recent decades have seen the development of new branches of semiotics, including biosemiotics, cognitive semiotics, and cybersemiotics. An important feature of these concepts is the question of the relationship between the linguistic and extralinguistic world: in particular, the constructivist question of the role of observation and the observer in semiosis. Problem: Our understanding of the observer’s role in the framework of second-order cybernetics is incomplete without understanding where in the observation the significant activity, semiosis, takes place. By describing this process, we will see that semiosis has the structure of an eigenform. I will concentrate on linguistic semiosis, and will illuminate the role of the sign and interpretation, emphasizing the scheme and logic of this process. Method: I use theoretical and conceptual methods of argumentation, such as logical (deductive) and philosophical (phenomenological) proofs and thought experiments. Results: My argumentation underlines the importance of including interpretation (via the observer) in the process of signification. It reveals the reciprocal connections among all three elements (sign, object and interpretant) and their cyclic nature. I show that semiosis works according to the principle of an eigenform because of the cyclic and recursive nature of semiotic interpretation. Implications: My conclusions have productive implications for epistemic theories, linguistic theories, philosophy of language, theories of semiology, and semantics. They support the idea that we are unable to understand the world beyond language. Linguistic semiosis is an eigenform that creates the world in itself and through itself. The sign and the object are mutually and referentially related to each other. Constructivist content: Using the concept of eigenform helps to clarify how linguistic semiosis allows people to exist in language, bring forth objects and meaning potentials and construct reality. In this process, human beings self-fabricate as observers and, using aspects of “language,” become interpreters.
