The Elements of Law Natural and Politic [3]
effect of lucid bodies: their difference being only this, that when the light cometh directly from the fountain to the eye, or indirectly by reflection from clean and polite bodies, and such as have no particular motion internal to alter it, we call it light. But when it cometh to the eyes by reflection from uneven, rough, and coarse bodies, or such as are affected with internal motion of their own, that may alter it, then we call it colour; colour and light differing only in this, that the one is pure, the other a perturbed light. By that which hath been said, not only the truth of the third proposition, but also the whole manner of producing light and colour, is apparent. 9. As colour is not inherent in the object, but an effect thereof upon us, caused by such motion in the object, as hath been described: so neither is sound in the thing we hear, but in ourselves. One manifest sign thereof is: that as a man may see, so also he may hear double or treble, by multiplication of echoes, which echoes are sounds as well as the original; and not being in one and the same place, cannot be inherent in the body that maketh them. Nothing can make any thing in itself: the clapper hath not sound in it, but motion, and maketh motion in the internal parts of the bell so the bell hath motion, and not sound. That imparteth motion to the air; and the air hath motion, but not sound. The air imparteth motion by the ear and nerves to the brain; and the brain hath motion but not sound. From the brain it reboundeth back into the nerves outward, and thence it becometh an apparition without, which we call sound. And to proceed to the rest of the senses, it is apparent enough, that the smell and taste of the same thing, are not the same to every man, and therefore are not in the thing smelt or tasted, but in the men. So likewise the heat we feel from the fire is manifestly in us, and is quite different from the heat that is in the fire. For our heat is pleasure or pain, according as it is extreme or moderate; but in the coal there is no such thing. By this the fourth and last of the propositions is proved (viz.) That as in conception by vision, so also in the conceptions that arise from other senses, the subject of their inherence is not the object, but the sentient. 10. And from thence also it followeth, that whatsoever accidents or qualities our senses make us think there be in the world, they are not there, but are seemings and apparitions only. The things that really are in the world without us, are those motions by which these seemings are caused. And this is the great deception of sense, which also is by sense to be corrected. For as sense telleth me, when I see directly, that the colour seemeth to be in the object; so also sense telleth me, when I see by reflection, that colour is not in the object.

Of Imagination and the Kinds Thereof
1. As standing water put into motion by the stroke of a stone, or blast of wind, doth not presently give over moving as soon as the wind ceaseth, or the stone settleth: so neither doth the effect cease which the object hath wrought upon the brain, so soon as ever by turning aside of the organ the object ceaseth to work; that is to say, though the sense be past, the image or conception remaineth; but more obscurely while we are awake, because some object or other continually plieth and soliciteth our eyes, and ears, keeping the mind in a stronger motion, whereby the weaker doth not easily appear. And this obscure conception is that we call PHANTASY or IMAGINATION: imagination being (to define it) conception remaining, and by little and little decaying from and after the act of sense. 2. But when present sense is not, as in SLEEP, there the images remaining after sense (when there be any) as in dreams, are not obscure, but strong and clear, as in sense itself. The reason. iS, because that which obscured and made the conceptions weak, namely sense, and present operation of the objects, is removed. For sleep is the privation of the act of sense, (the power remaining) and dreams
