How To Get It. Diagrammatic Reasoning As A Tool Of Knowledge Development And Its Pragmatic Dimension, Michael H.G. Hoffmann Jan 2004

How To Get It. Diagrammatic Reasoning As A Tool Of Knowledge Development And Its Pragmatic Dimension, Michael H.G. Hoffmann

Michael H.G. Hoffmann

Discussions concerning belief revision, theory development, and "creativity" in philosophy and AI, reveal a growing interest in Peirce's concept of abduction. Peirce introduced abduction in an attempt to provide theoretical dignity and clarification to the difficult problem of knowledge generation. He wrote that "An Abduction is Originary in respect to being the only kind of argument which starts a new idea." These discussions, however, have led to considerable debates about the precise way in which Peirce's abduction can be used to explain knowledge generation. The crucial question is that of understanding how we can get the new elements ...


Learning By Developing Knowledge Networks. A Semiotic Approach Within A Dialectical Framework, Michael H.G. Hoffmann, Wolf-Michael Roth Jan 2004

Learning By Developing Knowledge Networks. A Semiotic Approach Within A Dialectical Framework, Michael H.G. Hoffmann, Wolf-Michael Roth

Michael H.G. Hoffmann

A central challenge for research on how we should prepare students to manage crossing boundaries between different knowledge settings in life long learning processes is to identify those forms of knowledge that are particularly relevant here. In this paper, we develop by philosophical means the concept of a dialectical system as a general framework to describe the development of knowledge networks that mark the starting point for learning processes, and we use semiotics to discuss (a) the epistemological thesis that any cognitive access to our world of objects is mediated by signs and (b) diagrammatic reasoning and abduction as those ...
