Influences

His philosophical ideas were deeply influenced by the writings of

Gottlob Frege Friedrich Ludwig Gottlob Frege (; ; 8 November 1848 – 26 July 1925) was a German philosopher, logician, and mathematician. He was a mathematics professor at the University of Jena, and is understood by many to be the father of analytic p ...

and despite his critique of logicism he also learnt much from John McCarthy. His work on emotions can be seen as an elaboration of a paper on "Motivational and emotional controls of cognition", written in the 1960s by Herbert A. Simon. He disagrees with all of these on some topics, while agreeing on others.

Recognition

He is a Fellow of Association for the Advancement of Artificial Intelligence, Society for the Study of Artificial Intelligence and the Simulation of Behaviour and European Coordinating Committee for Artificial Intelligence. In 2018, he became a Fellow of the Alan Turing Institute.

awarded him an honorary Doctorate of Science in July 2006. The Sloman Lounge in the School of Computer Science at the University of Birmingham is named in his honour. In 2020 the American Philosophical Association (APA) awarded him the K.Jon Barwise Prize "for significant and sustained contributions to areas relevant to philosophy and computing". https://www.apaonline.org/page/2020Prizes-S
