 Different views on the theme of basic forms of intentionality will face different challenges in accounting for the sources of our knowledge, or of warrant for our mundane beliefs about the things we find around us. Roughly, it might seem that in certain respects, the story of justification will be easier, the more the intentionality of sensory experience is assimilated to that of full-blown concept-applying judgment or belief—inasmuch as it seems unmysterious how beliefs justify beliefs. On the other hand, going very far in that direction can bring puzzles of its own. It seems that sense experience should be of the right sort to enable us to acquire concepts (which assumes we don’t already have them), and to support our applying concepts to things (which assumes we haven’t already done so). But it may seem harder to maintain these assumptions, if we make sensory experience itself a kind of judgment or belief (see the discussion in Siegel and Silins 2015).
