Author Description

The interest in multidisciplinary approaches to the study of rationality and knowledge seems to be as strong as it was twenty-one years ago when the first TARK conference was launched. We see this in the number of submissions to TARK 2007 -- one hundred, which is the second highest for the eleven TARK conferences held since 1986. Thirty two papers were accepted, which is a record high for TARK. In order to accommodate all these papers in three days, 10 of them are presented in a poster session, which is new to TARK.
