DIFFERENCE BETWEEN INTELLIGIBLE AND SENSE-QUALITY.
3. The whiteness that I see in you is not a quality, but an actualization of the potentiality of whitening. In the intelligible world all the things that we call qualities are actualizations. They are called qualities because they are properties, because they differentiate the beings from each other, because in respect to themselves they bear a particular character. But since quality in the sense-world is also an actualization, in what does it differ from the intelligible quality? The sense-quality does not show the essential quality of every being, nor the difference or character of substances, but simply the thing that we properly call quality, and which is an actualization in the intelligible world. When the property of something is to be a being, this thing is not a quality. But when reason separates beings from their properties, when it removes nothing from them, when it limits itself to conceiving and begetting different from these beings, it begets quality, which it conceives of as the superficial part of being. In this case, nothing hinders the heat of the fire, so far as it is natural to it, from constituting a form, an actualization, and not a quality of the fire; it is a quality when it exists in a substance where it no longer constitutes the form of being, but only a trace, an adumbration, an image of being, because it finds itself separated from the being whose actualization it is.
QUALITIES ARE ACCIDENTAL SHAPES OF BEING.
Qualities, therefore, are everything that, instead of being actualizations and forms of beings, are only its accidents, and only reveal its shapes. We will therefore call qualities the habituations and the dispositions which are not essential to substances. The archetypes (or models) of qualities are the actualizations of the beings, which are the principles of these qualities. It is impossible for the same thing at one time to be, and at another not to be a quality. What can be separated from being is quality; what remains united to being is being, form, and actualization. In fact, nothing can be the same in itself, and in some other condition where it has ceased to be form and an actualization. What, instead of being the form of a being, is always its accident, is purely and exclusively a quality.

Do Ideas of Individuals Exist?
TWO POSSIBLE HYPOTHESES OF IDEAS OF INDIVIDUALS.
1. Do ideas of individuals (as well as of classes of individuals), exist? This means that if I, in company with some other man, were to trace ourselves back to the intelligible world, we would there find separate individual principles corresponding to each of us. (This might imply either of two theories.) Either, if the individual named Socrates be eternal, and if the soul of Socrates be Socrates himself, then the soul of each individual is contained in the intelligible world. Or if, on the contrary, the individual named Socrates be not eternal, if the same soul can belong successively to several individuals, such as Socrates or Pythagoras, then (as Alcinoous, e. g., and other Platonists insist), each individual does not have his idea in the intelligible world.
