A Reaction

He refers to 'qualities' rather than 'properties', presumably because this view makes them all intrinsic to the object. Is being 'handsome' a part of a person?


The 8 ideas with the same theme [nature of the characteristics we perceive]:

Sensible qualities can't be real if they appear different to different creatures [Democritus, by Theophrastus]
A 'quality' is a power to produce an idea in our minds [Locke]
We examine objects to determine colour; we do not introspect [Jackson]
Some say qualities are parts of things - as repeatable universals, or as particulars [Lewis]
If properties were qualities without dispositions, they would be undetectable [Heil]
Can we distinguish the way a property is from the property? [Heil]
Properties don't possess ways they are, because that just is the property [Heil]
Properties or qualities are essentially adjectival, not objectual [Lowe]
