Phil. And can a line so situated be perceived by sight?
Hyl. It cannot.
Phil. Doth it not therefore follow that distance is not properly and immediately perceived by sight?
Hyl. It should seem so.
Phil. Again, is it your opinion that colours are at a distance[814]?
Hyl. It must be acknowledged they are only in the mind.
Phil. But do not colours appear to the eye as coexisting in the same place with extension and figures?
Hyl. They do.
Phil. How can you then conclude from sight that figures exist without, when you acknowledge colours do not; the sensible appearance being the very same with regard to both?
Hyl. I know not what to answer.
