since the manner wherein the mind apprehends by sight the motion of
tangible objects, with the various degrees thereof, may be easily
collected from what hath been said concerning the manner wherein that
sense doth suggest their various distances, magnitudes, and situations, I
shall not enlarge any farther on this subject, but proceed to consider
what may be alleged, with greatest appearance of reason, against the
proposition we have shown to be true. For where there is so much
prejudice to be encountered, a bare and naked demonstration of the truth
will scarce suffice. We must also satisfy the scruples that men may raise
in favour of their preconceived notions, show whence the mistake arises,
