Natural Concepts and the Economics of Cognition and Communication
This article takes a cognitive approach to natural concepts. The aim is to introduce criteria that are evaluated with respect to how they support the cognitive economy of humans when using concepts in reasoning and communicating with them. I first present the theory of conceptual spaces as a tool for expressing the criteria. Then I introduce the central idea that natural concepts correspond to convex regions of a conceptual space. I argue that this criterion has far-reaching consequences as regards natural concepts. Partly following earlier work, I present some other criteria that further delimit the class of natural concepts. One of these is coherence, which does not seem to have been discussed previously. Finally, I show that convexity and other criteria make it possible to ensure that people mean the same thing when they communicate using concepts. Apart from its philosophical interest, the analysis presented in the article will be relevant for tasks of conceptual engineering in artificial systems that work with concepts.
期刊介绍：
Founded in 1971, Philosophia is a much-respected journal that has provided a platform to many well-known philosophers, including Kenneth Arrow, A.J. Ayer, Roderick Chisholm, Bas van Fraassen, William Frankena, P.T. Geach, Alan Gewirth, Jaakko Hintikka, Richard Popkin, W.V.O. Quine, Gilbert Ryle, Marcus Singer, Peter Singer, J.J.C. Smart, P.F. Strawson, and many others. Philosophia also published papers of Ludwig Wittgenstein and Rudolf Carnap.
Philosophia is an international journal in scope, submissions and readership. The journal publishes contributions fitting within various philosophical traditions, but manifests a preference of the analytic tradition in the broad sense of commitment to clarity and responsibility.
Besides papers in the traditional subfields of philosophy and its history, Philosophia also publishes work on topical subjects such as racism, silence of God, terrorism, the nature of philosophy, emotion, AIDS, scientific discovery, punishment, modality, and institutional theory of art.
Philosophia welcomes a wide range of contributions to academic philosophy, covering all fields of philosophy. Contributions to the journal may take the form of topical papers, philosophical surveys of literature, symposia papers, short discussion notes, puzzles, profiles, book reviews and more extensive critical studies of new books. The journal includes a ''books revisited'' section where a book and its impact are reconsidered a decade or more after its appearance. Double-blind review procedure The journal follows a double-blind reviewing procedure. Authors are therefore requested to place their name and affiliation on a separate page. Self-identifying citations and references in the article text should either be avoided or left blank when manuscripts are first submitted. Authors are responsible for reinserting self-identifying citations and references when manuscripts are prepared for final submission.Please read our Editorial Policies carefully before you submit your paper to this journal https://www.springer.com/gp/editorial-policies
