 Daniel Cohen (1995) suggests that antagonistic attitudes may not actually enhance competition and the knowledge it is supposed to serve, and that imposing the goal of agreement can silence rational discourse and undermine the goal of philosophy to further inquiry. The value of information that challenges our own beliefs can always be hard to recognize, a difficulty described as “confirmation bias”, and this problem can be exacerbated when the focus of arguing is winning rather than learning or ascertaining truth (Makau &amp; Marty 2013: 39–40, 167; Linker 2015).
