An Analysis of "The Hobbes Game"
Teach Phil, 18(3), 257-268, S95
John Immerwahr's 1976 classroom simulation is introduced to a new generation of teachers with practical suggestions on conducting the game and philosophical discussion on its game-theoretic implications. The game is designed as a analog of Hobbes' model of the mutual transfer of rights in the formation of a social contract. From an analysis of the outcomes of fifteen games with the help of game theory, Immerwahr's simulation is seen to be an effective pedagogical tool for understanding ethical conflicts.

A Simple Defense of Material Implication
Published in 'Notre Dame Journal of Formal Logic' http://projecteuclid.org/euclid.ndjfl/1093882818.
This simple defense of material implication helps clarify the debate between the orthodox logicians, who claim 'If p then q' and 'p |horseshoe| q' are not interderivable and the nonorthodox logicians, who claim that the two expressions are interderivable. The paper shows the orthodox logician must deny that ordinary language arguments of the form modus ponens and modus tollens are truth-functional in any consistent sense on three lines of the truth-table.

Hume's Considered View on Causality
Philosophy of Science Archive http://philsci-archive.pitt.edu/archive/00002247/
Hume presents two definitions of cause in his Enquiry which correspond to his two definitions in his Treatise. The first of the definitions is ontological and the second is psychological; indeed, the definitions are extensionally and intensionally distinct. The critical mistake of the skeptical interpretation is the assumption that the two definitions are equivalent, and the critical mistake of the necessitarian is the assumption an association of ideas can be had from one experiment. This paper attempts to clarify Hume’s finally considered position of causality.
