  Although it can be argued that it arises even in a  connectionist setting (Haselager &amp; Van Rappard 1998; Samuels 2010), the frame problem inherits much of its philosophical significance from the classical assumption of the explanatory value of computation over representations, an assumption that has been under vigorous attack for some time (Clark 1997; Wheeler 2005).  Despite this, many philosophers of mind, in the company of Fodor and Pylyshyn, still subscribe to the view that human mental processes consist chiefly of inferences over a set of propositions, and that those inferences are carried out by some form of computation. To such philosophers, the epistemological frame problem and its computational counterpart remain a genuine threat.
