Many philosophers are familiar with the distinction between thin and thick concepts.  Canonical examples of thin concepts include goodness and badness, rightness and wrongness.  There are supposedly many examples of thick concepts, including cruelty, kindness, beauty, elegance, and curiosity.  A number of issues arise in relation to thin and thick concepts.  Many might be familiar with a key debate, namely how one should construe the relationship between thick concepts’ supposed descriptive aspects and their supposed evaluative aspects.  Do we have here two separable elements, or are they best characterized as essentially inseparable, resulting in a form of evaluation that is more specific than that found in thin concepts?  There might also be some familiarity with other issues raised, for example the question of whether either sort of concept allows one to think and judge in ways that make evaluative knowledge (or something like it) a possibility and stable.  But there are other issues that tend not to be as well known.  For example, is there a difference in kind between thin and thick concepts or is there only a difference of degree?  If the former, how might it be made out? Furthermore, although writers will often use thick ethical concepts as their main examples, it is commonly acknowledged that thick concepts crop up in many areas of everyday thought.  Are there any key differences between, say, ethical and aesthetic thick concepts, differences in how they behave as thick concepts?  Thick ethical concepts might have some degree of normativity, but how is this aspect related to the evaluative aspect and is it present in typical aesthetic concepts?  And, in all of this, is there any difference of note between thick language, thick concepts, and (supposed) thick features?

There are many other relevant issues.  What is notable about most of the questions concerning thick concepts is that there is relatively little written on them, despite the familiarity of the distinction between the thin and the thick.  There are some articles here, and some discussions in books there.  However, a few writers are beginning to investigate and study thin and thick concepts systematically, including some of the invited speakers.  The principal aim of this conference is to bring together a number of philosophers of international repute who are interested in thick concepts so that they can both pursue some of the familiar debates, and raise and discuss new questions and ideas.  It is envisaged that the discussions will be of interest to moral philosophers, aestheticians, epistemologists, metaphysicians, and philosophers of language amongst others.

Call for Papers:

There will be open sessions in which some non-invited speakers can present their work.  Papers dealing with any aspect of thick concepts are encouraged.  Submissions should be emailed to the conference organiser, Simon Kirchin, at:

by Monday 2nd February 2009.  Submissions should be prepared for blind review, be a maximum of 2,000 words long, have an additional 200 word abstract at the start, and contain lines of thought presentable in 20 minutes.  The author’s name, affiliation, and email address should be sent in a separate file.  Word or PDF files are preferred. Decisions will be made by 30th April 2009.  Postgraduates in particular are encouraged to apply, with a prize of 50 pounds available for the best postgraduate talk. (Speakers in the open sessions will not be reimbursed for any costs incurred.)

A conference website, with details about bookings, etc., will appear early in 2009.
