The tension between the need for critique and its (often unperceived) limits through our given common sense, a tension Charles S. Peirce describes as critical common sense, hasn’t lost its actuality. Vague certainty is one root of this tension, which the paper unfolds by distinguishing two forms: while the first one grounds common sense as a form of life, the second one, self-certainty, represents the purpose of endeavors, and it serves, speaking with Pierre Bourdieu, as a form of distinction (1). (...) As part of an indifference towards power structures of exclusion, vague certainties contribute to what Judith Butlers describes as the violent derealization of others, which is being discussed in the light of the Black Lives Matter and Me Too movement. (Self-)certainty, as is being shown, is not (merely) an epistemological matter, but encompasses the fields of the political and aesthetic. Accordingly, as a crucial part of political critique and practices to counter (self-)certainties, a differentiation of doubting is required – the paper proposes four different kinds: authoritarian, anti-authoritarian, acknowledging and imaginative doubting. They help understand the political struggles of re-realizing formerly derealized positions within society (2). Particularly through imaginative doubting, some shortcomings within Peirce’s notion of the self (and, for that matter, within the pragmatist notion of doubting) are being overcome by showing how to link it to creative processes of abduction, which in turn have consequences for political matters by unsettling implicit consent, or, in the words of Jacques Rancière, the partition of the sensible (3).

Our brains make up a series of signs and are engaged in making or manifesting or reacting to a series of signs: through this semiotic activity they are at the same time engaged in “being minds.” An important effect of this semiotic activity of brains is a continuous process of “externalization of the mind” that exhibits a new cognitive perspective on the mechanisms underlying the semiotic emergence of abductive processes of meaning formation. I consider this process of externalization interplay critical (...) in analyzing the relation between meaningful semiotic internal resources and devices and their dynamical interactions with the externalized semiotic materiality suitably stocked in the environment. The last part of the paper will describe some aspects of this interplay between external diagrammatization and internal recapitulation showing the specificity of their co-evolution. (shrink)

In this paper we maintain that abductive inferential processes should be embedded to a more general outlook on human cognition. Abduction has clear a.nities to the so-called interrogative model of inquiry in which inquiry and reasoning are conceptualized as a dialogue. We think, in addition, that dialogicality must be broadened to a “trialogical” framework which means a threefold relationship with mediating artefacts where the inquirer, other inquirers , and the object of knowledge are inextricably bound up with each other in (...) long term processes of inquiry. Seen from this perspective Peirce's semeiotic pragmatism has close connections to modern ideas about distributed cognition; also to Pera's dialectical model of science, and Davidson's theory of triangulation concerning human mind, cognition, and knowledge.
