Colour, Figure, Motion, Extension and the like, considered only so many Sensations in the Mind, are perfectly known, there being nothing in them which is not perceived. But if they are looked on as notes or Images, referred to Things or Archetypes existing without the Mind, then are we involved all in Scepticism.
George BerkeleyIt is a mistake, to think the same thing affects both sight and touch. If the same angle or square, which is the object of touch,be also the object of vision, what should hinder the blind man, at first sight, from knowing it?
