When we perceive something, we can be aware of many items.For example, we can be aware of low-level properties such as object's color, shape, motion and place. Also we can be aware of highlevelproperties or features such as causal relation, disposition, kindproperty, mental state of others, absence of something, and affordance.Among these properties, which ones are we aware of by perception,and which ones by thought(interpretation, judgement, inference)?Low-level theorist claims that we can perceive only low-levelproperties, and that we are aware of high-level properties bythought. On the contrary, high-level theorist claims that we can perceivesome high-level properties in addition to low-level properties.This paper aims to show that the low-level theory is false. First, Ishow that reasons which support the low-level theory, in themselves,are not enough to exclude high-level properties from perceptual content.Next, I explain that phenomenal difference between expert andnovice suggests that expert's perceptual content include high-levelproperties. But low-level theorist can object this difference can beconstrue not as high-level- but as the difference of low-level propertiesperceived. To reply this objection, I argue that some cases of agnosiasuggest perceptual content has non-low-level property. Finally,I consider what is needed to regard this non-low-level property ashigh-level property.
