This year's edition of Kazimierz Naturalized Epistemology Workshop (1st-5th September 2007) will focus on relations between naturalized epistemology and artificial cognitive systems. The prospective keynote speakers are

• Don Favareau (National University of Singapore)
• Maria Frapolli (University of Granada)
• Stevan Harnad (University of Quebec at Montreal and University of Southampton)
• Hilary Kornblith (University of Massachusetts Amherst)
• Ulrich Krohs (University of Hamburg)

You'll find more information here and here (the latter isn't updated due to some technical problems but should be fixed till the end of the week). I'm one of the organizers, so feel free to ask
