Friendship constitutes an integral part of human flourishing. Aristotle (1996) famously wrote, ‘For no one would choose to live without friends, but possessing all other good things’ (p. 205). Members of our respective practice communities (MacIntyre, 1984) understand and appreciate our passion for running or basketball, tennis or cycling. The friends we develop through sport, and herein I focus on running, have the potential to help us cultivate human flourishing in the Aristotelian sense. Highlighting this point, Austin (2007) writes that (...) ‘The friendships of runners often illustrate Aristotle’s understanding of this highest form of friendship, as well as friendship in its lower forms. And as we shall see, running is well suited for fostering the type of friendship that Aristotle thinks is necessary for being happy’ (p. 12). In his book, Philosophy Americana, Anderson (2006) provides an overview of the themes which pervade the academic discipline known as American philosophy. Individuals typically cited within this domain include Charles Sanders Peirce, William James, Josiah Royce, and John Dewey, among others. Examining the nature of running friendships provides a way to explicate American philosophical themes; and the themes provide a means to more fully understand and appreciate the nature of running friendships. My purpose here is to examine running friendships through the lens of the American philosophical tradition. The themes I have in mind here are: patience; commitment and immersion; risk and precipitousnes; and experience. I begin with an overview of friendship, including friendship as a form of human flourishing as well as the formation of friendship. I then transition to an examination of American philosophical themes related to running and friendship. (shrink)
