PHIL. It seems then the light doth no more than shake the optic nerves.
HYL. Nothing else.
PHIL. And consequent to each particular motion of the nerves, the mind is affected with a sensation, which is some particular colour.
HYL. Right.
PHIL. And these sensations have no existence without the mind.
HYL. They have not.
PHIL. How then do you affirm that colours are in the light; since by LIGHT you understand a corporeal substance external to the mind?
HYL. Light and colours, as immediately perceived by us, I grant cannot exist without the mind. But in themselves they are only the motions and configurations of certain insensible particles of matter.
PHIL. Colours then, in the vulgar sense, or taken for the immediate objects of sight, cannot agree to any but a perceiving substance.
HYL. That is what I say.
