Mathematics can be defined not only as the study of patterns but also as the study of logical arguments and deductive reasoning. Most research mathematicians find beauty in the elegant structure of mathematical proofs. Just as patterns lend beauty to the visual, musical, poetical, and design arts in which they are found, the structure of mathematical thinking can be found applied throughout history in various corners of the humanities, lending its clarity of argument and elegance of presentation to a sometimes unexpected context. In this talk, we consider a brief survey of the applications of specifically mathematical thought to philosophical and theological questions, from the Pythagoreans through the Ontological Argument of Descartes to contemporary interpretations of Chaos Theory. Disclosure: this is neither Philosophy of Mathematics nor Philosophy from a trained philosopher; the level is targeted for bridge-building in the liberal arts education of our students.
