However, the correct analysis of Dalton’s belief and the way it relates to contemporary beliefs about atoms is, on closer inspection, far from straightforward. In this paper, I introduce four features that any candidate analysis is plausibly bound to respect. I argue that theories that individuate concepts at the level of understanding are doomed to fail in this endeavor. I formally sketch an alternative and suggest that cases such as the one presented provide support for the claim that the genuine source for concept individuation is public sharable thought.application/pdfeng© This is an Accepted Manuscript of an article published by Taylor & Francis in International Journal of Philosophical Studies on 11 Jan 2016, available online: http://www.tandfonline.com/10.1080/09672559.2015.1126339info:eu-repo/semantics/articleBelief ascriptionconcept possessiondisagreementcommunicationunderstandingsenseinfo:eu-repo/semantics/openAccess
