Empirical facts about perception may be useful, and the physical theories of perception need not be challenged
E.g. gestalt psychology could be important to phenomonology
Notion of ‘perceptual features’. Empirical question:
Is it that to perceive is, essentially, to perceive objects? Every perception is a perception of something?
alternatively, we could also perceive ‘features’, too
More generally, is perception uniform or is there a richness/complexity of kind in the types of perception? This could influence philosophers who need to discuss the uses of perception.
In some sense, this is just a boring/trivial question about the grammar of perception.
Interesting empirical question: what is the privileged form of perceputal sensations - how far are we (always) breaking down sense data into objects? What physical mechanism does this?
