It differs from the logical/mathematical concept of class by not having any concept of extensionality, and from the philosophical concept of class in that a property is considered to be distinct from the objects which possess it. A second hybrid view claims that properties have both a categorical(qualitative) and dispositional part, but that these are distinct ontological parts.
