      §3. A Painter or Dyer, who never enquired into their causes, hath
the Ideas of White and Black, and other Colours, as clearly, perfectly,
and distinctly in his Understanding, and perhaps more distinctly,
than the Philosopher, who hath busied himself in considering their
Natures, and thinks he knows how far either of them is in its cause
positive or privative; and the Idea of Black is no less positive in his
Mind, than that of White, however the cause of that Colour in the
external Object, may be only a privation.
Locke Hum II, 8, §3, p. 133
