Perception, Language and Cognitive Success

Abstract

I compare three types o perception: perception X, perception as…, and perception
that… to decide which type is cognitively the most promising. Commonly,
perception that… is taken to be epistemically superior as both propositional and
factive. I argue in favour of perception as… which implies revealing new
aspects. I analyze two standard cases: the ‘bent stick’ illusion and the
‘duck-rabbit’ picture to explain how seeing new aspects engages language usage,
transcends factivity and becomes heuristic.
