Phil. And, in the same way that Julius Cæsar, in himself invisible, is nevertheless perceived by sight; real things, in themselves imperceptible, are perceived by sense.
Hyl. In the very same.
Phil. Tell me, Hylas, when you behold the picture of Julius Cæsar, do you see with your eyes any more than some colours and figures, with a certain symmetry and composition of the whole?
Hyl. Nothing else.
Phil. And would not a man who had never known anything of Julius Cæsar see as much?
Hyl. He would.
Phil. Consequently he hath his sight, and the use of it, in as perfect a degree as you?
Hyl. I agree with you.
Phil. Whence comes it then that your thoughts are directed to the Roman emperor, and his are not? This cannot proceed from the sensations or ideas of sense by you then perceived; since you acknowledge you have no advantage over him in that respect. It should seem therefore to proceed from reason and memory: should it not?
Hyl. It should.
