Communication between rational agents can be seen as an exchange of internal concepts expressed using a shared language. Most of the communication acts between humans are performed through Natural Language (NL), and the meaning of the expressions of the language adopted is assumed to be known and properly understood by all of the participants. This suggests that the process of communication usi...

Cognitive frameworks and belief systems are the primary lenses through which presidents view the world. Two important questions are whether these beliefs ever change significantly, and if so, what causes these changes? This article develops empirical data on the strategic and operational beliefs of President George W. Bush (GWB) as a means of examining the theoretical basis for how and why core...

Due to the growing complexity of multi-state deteriorating systems and lack data, information knowledge, epistemic uncertainty cannot be ignored anymore. Although there already exist some reliability metrics deal with problems in systems, final results provided by these methods are always probability intervals, which will suffer from interval extension challenge subsequent operation. In this pa...

We consider belief revision operators that satisfy the Alchourrr on-GG ardenfors-Makinson postulates, and present an epistemic logic in which, for any such revision operator, the result of a revision can be described by a sentence in the logic. In our logic, the fact that the agent's set of beliefs is is represented by the sentence O, where O is Levesque's `only know' operator. Intuitively, O i...

E conomics and environmentalism are belief systems that shape their adherents’ way of thinking about the world. We might just as accurately characterize them as secular religions, which most theologians count as real religions (see, for example, Tillich 1963), but many people prefer to regard them as competing belief systems. Many (not all) economists and environmentalists thus function in the ...

A group of 29 college students who had been arrested or nominated as having participated in a street disturbance aimed at producing social change were interviewed. The interview schedule was highly similar to one which had been used to investigate attitudes toward violence in a random, representative sample of American men. The data collected from the arrestees are compared with data from colle...

Double dissociations between perceivable colors and physical properties of colored objects have led many philosophers to endorse relationalist accounts color. I argue that there are analogous double attitudes belief—the beliefs people attribute each other in everyday life—and intrinsic cognitive states some scientists posit as cogs systems—pitched at every level psychological explanation. These...

Abstract Thagard (1992) presented a framework for conceptual change in science based on systems. challenged belief revision theorists, claiming that traditional belief-revision systems are able to model only the two most conservative types of changes his framework, but not more radical ones. The main aim this work is take up Thagard’s challenge, presenting belief-revision-like system mirror cha...
