The statement "A sense organ that perceives a property also perceives the propertyness as well as the absence of that property" can be attributed to which school of classical Indian philosophy?

The doctrine that a sense organ grasping a quality also grasps its propertyness and its absence belongs to Nyaya.

Nyaya holds that perception reaches not only an object but the qualities inhering in it.

Along with the property, its generic character (propertyness) is also apprehended.

Nyaya further admits that absence (abhava) is itself an object of perception.

So the very organ that sees a property can also perceive where that property is lacking.

This realist account of perceiving qualities and absences is characteristic of the Nyaya school.
