    How Many Impossible Images Did Escher Produce?
    with Chris Mortensen, Steve Leishman, and Theresa Helke
    British Journal of Aesthetics 53 (4): 425-441. 2013.
    In this article we address the question of how many impossible images Escher produced. To answer requires us first to clarify a range of concepts, including content, ambiguity, illusion, and impossibility. We then consider, and reject, several candidates for impossibility before settling on an answer

    Cubic logic, Ulam games, and paraconsistency
    Journal of Applied Non-Classical Logics 15 (1): 59-68. 2005.
    In this paper we call for attention to be paid to the link between logic and geometry. To apply this theme, we survey the connection between n-cubes, Lukasiewicz logics and Ulam games. We then extend what is known to the case where the number of permitted lies in a Ulam game exceeds 1. We conclude by identifying the precise sense in which these logics are paraconsistent

    I argue that with the advent of poststructuralism, traditional theories of representation, truth, and resistance have been seriously brought into question. References to the “natural” and the “wild” cannot escape the poststructural attack against foundational concepts and the constituting character of human-centered language. I explore the ways in which environmental movements and literary expression have tended to posit pre-ideological essences, thereby replicating patterns of power and authori…Read more

    Ecocritical aesthetics: language, beauty, and the environment (edited book)
