David Lewis is widely regarded as the philosopher who introduced the concept of common knowledge. His account of common knowledge differs greatly from most later accounts in philosophy and economy, with the central notion of his theory being ‘having reason to believe’ rather than ‘knowledge’. Unfortunately, Lewis’s account is rather informal, and the argument has a few gaps. This paper assesses two major attempts to formalise Lewis’s account and argues that these formalisations are missing a crucial aspect of this account. Therefore, a new reconstruction is proposed, which explicitly discusses ‘reasons’ and uses a logic inspired by justification logic.
期刊介绍:
The disciplines of economics and philosophy each possess their own special analytical methods, whose combination is powerful and fruitful. Each discipline can be enriched by the other. Economics and Philosophy aims to promote their mutual enrichment by publishing articles and book reviews in all areas linking these subjects. Topics include the methodology and epistemology of economics, the foundations of decision theory and game theory, the nature of rational choice in general, historical work on economics with a philosophical purpose, ethical issues in economics, the use of economic techniques in ethical theory, and many other subjects.
