There is nothing like our ideas, existing in the bodies themselves.

They are, in the bodies we denominate from them, only a power to produce those sensations in us: and what is sweet, blue, or warm in idea, is but the certain bulk, figure, and motion of the insensible parts, in the bodies themselves, which we call so.

Examples.
Flame is denominated hot and light; snow, white and cold; and manna, white and sweet, from the ideas they produce in us.

Which qualities are commonly thought to be the same in those bodies that those ideas are in us, the one the perfect resemblance of the other, as they are in a mirror, and it would by most men be judged very extravagant if one should say otherwise.

And yet he that will consider that the same fire that, at one distance produces in us the sensation of warmth, does, at a nearer approach, produce in us the far different sensation of pain, ought to bethink himself what reason he has to say--that this idea of warmth, which was produced in him by the fire, is ACTUALLY IN THE FIRE; and his idea of pain, which the same fire produced in him the same way, is NOT in the fire.
