The mobile era of electronic communication has created a huge semiotic system, constructed out of triadic components envisaged by the American scientist and philosopher Charles S. Peirce (1839–1914), such as icons, indices and symbols, and signs, objects and interpretants. Iconic signs bear a physical resemblance to what they represent. Indices point at something and say “there!”, and symbols s...

Abductive reasoning algorithms formulate possible hypotheses to explain observed facts using a theory as the basis. These algorithms have been applied to various domains such as diagnosis, planning and interpretation. In general, algorithms for abductive reasoning based on logic present the following disadvantages: (1) they do not allow the explicit declaration of conditions that may affect the...

This paper comments upon some of the open problems in artificial life (cf. Bedeau et al 2000) from the perspective of a philosophy of biology tradition called qualitative organicism, and more specifically the emerging field of biosemiotics, the study of life processes as sign processes. Semiotics, in the sense of the pragmaticist philosopher and scientist Charles S. Peirce, is the general study...

Abduction and induction are reasoning forms for drawing conclusions from incomplete information. Induction, i.e. inferring properties of sets of individuals from properties of individuals, was already distinguished by Aristotle, while the term ‘abduction’ was introduced much later by Peirce for inference of explanations for observed phenomena. Both reasoning forms are presently being studied an...
