This workshop will bring together philosophers and scientists to discuss the role and uses of information and representation in physics, biology and the cognitive sciences. What are the explanatory roles of ‘information’ and ‘representation’ in theories in physics, biology and cognitive science? What is the relation amongst probability, entropy and information as well as between information and representation? Is it theoretically useful to aim at single, all encompassing theories of information and representation (one size fits all)? Addressing these questions in a single workshop is especially important in view of the central roles ‘information’ and ‘representation’ play in different disciplines and sciences.
