Jaakko Hintikka is an eminent logician and philosopher, born in Finland and currently a full professor at Boston University. He won the 2005 Rolf Schock prize in logic and philosophy for for his pioneering contributions to the logical analysis of modal concepts, in particular the concepts of knowledge and belief. He is regarded as the founder of formal epistemic logic , and an early pioneer in the semantics of modal logic who proposed a formal semantics essentially analogous to Kripke's frame semantics. He is currently working most intensively on his independence-friendly logic , a logic that he maintains reflects fundamental intuitions about quantifiers better than first-order logic does, and is specified by means of its game semantics. He has provided important exegetical work of Ludwig Wittgenstein.
