Welcome to my web page. I am a professor of Philosophy retired from the University of Wisconsin at Parkside, and here you will find my thoughts, and various writing projects in progress, including a number of translations of medieval logical texts. If you want to use or copy something, as long as you give me due credit, feel free to do so. I hope you find something interesting.

Demonstration and Scientific Knowledge in William of Ockham: A Translation of Summa Logicae III-II: De Syllogismo Demonstrativo, and selections from the Prologue to the Ordinatio. Notre Dame, Indiana: University of Notre Dame Press, 2007. This includes a long introductory study of medieval work on demonstration from Grosseteste and some of his predecessors through Albertus Magnus, Thomas Aquinas, and Duns Scotus, as well as additional translations from Giles of Rome and John of Cornwall. Reviews: “His careful translation, compilation of relevant documents, and impressive history of medieval empiricism should interest any scholar studying the history of philosophy of science.” *Alexander Hall, Journal of the History of Philosophy 46 (2008). *Anne Davenport, Isis 99:4 (2008). “In sum, this is an outstanding introduction to and translation of Ockham’s treatises on or related to the demonstrative syllogism. The commentary is illuminating, especially in those cases where Longeway makes abundantly clear why Ockham thought that the causal powers of things and causal relations can be known only by experience, and why he maintained that qualities can have causal powers. These views support Longeway’s conclusion about Ockham as the founder of empiricism in the European tradition.” Andre Goddu, Notre Dame Philosophical Reviews, 2014.
