8. Our ideas and the qualities of bodies.
Whatsoever the mind perceives in itself, or is the immediate object of
perception, thought, or understanding, that I call idea; and the power to produce any idea in our mind, I call
quality of the subject wherein that power is. Thus a snowball having the power to produce in us the ideas of white,
cold, and round,--the power to produce those ideas in us, as they are in the snowball, I call qualities; and as they
are sensations or perceptions in our understandings, I call them ideas; which ideas, if I speak of sometimes as in
the things themselves, I would be understood to mean those qualities in the objects which produce them in us.
