    Self-reference and the acyclicity of rational choice
    Annals of Pure and Applied Logic 96 (1-3): 117-140. 1999.
    Self-reference in semantics, which leads to well-known paradoxes, is a thoroughly researched subject. The phenomenon can appear also in decision theoretic situations. There is a structural analogy between the two and, more interestingly, an analogy between principles concerning truth and those concerning rationality. The former can serve as a guide for clarifying the latter. Both the analogies and the disanalogies are illuminating.

    On ontology and realism in mathematics
    Review of Symbolic Logic 5 (3): 480-512. 2012.
    The paper is concerned with the way in which “ontology” and “realism” are to be interpreted and applied so as to give us a deeper philosophical understanding of mathematical theories and practice. Rather than argue for or against some particular realistic position, I shall be concerned with possible coherent positions, their strengths and weaknesses. I shall also discuss related but different aspects of these problems. The terms in the title are the common thread that connects the various sectio…Read more

    A reason for theoretical terms
    with DanielN Osherson and Scott Weinstein
    Erkenntnis 32 (2). 1990.
    The presence of nonobservational vocabulary is shown to be necessary for wide application of a conservative principle of theory revision.
