1 Erratum to: Synthese DOI 10.1007/s11229-012-0184-x

Due to miscommunication the sequence of the articles in this special issue has been changed: the article that was meant to be the first (Jie W. Weiss & David J. Weiss, Irrational—at the moment), now appears as the last. This has led to an inconsistency in the introduction, where this article is presented as the first. We apologize for any inconvenience this may cause to the reader.
