‘Fine, Invisible Threads’: Schopenhauer on the Cognitively Mediated Structure of Motivation by Sean T. Murphy

“…Despite this avowedly intellectualist handling of the subject, some commentators remain convinced that Schopenhauer is best read as accepting the ‘Humean truism’ that reason alone never motivates; rather, motivation always has its source in desire together with instrumental belief (Young 1987). Here, I raise some doubts for the Humean reading by arguing that it does not take sufficient account of the transformative effects of cognitive mediation, effects which support cases of non-desiderative motivation. …”
