For after the object is removed, or the eye shut, wee still retain an image of the thing seen, though more obscure than when we see it.

And this is it, that Latines call Imagination, from the image made in seeing; and apply the same, though improperly, to all the other senses.

But the Greeks call it Fancy; which signifies Apparence, and is as proper to one sense, as to another.

Imagination therefore is nothing but Decaying Sense; and is found in men, and many other living Creatures, as well sleeping, as waking.
Memory The decay of Sense in men waking, is not the decay of the motion made in sense; but an obscuring of it, in such manner, as the light of the Sun obscureth the light of the Starres; which starrs do no less exercise their vertue by which they are visible, in the day, than in the night.
But because amongst many stroaks, which our eyes, eares, and other organs receive from externall bodies, the predominant onely is sensible; therefore the light of the Sun being predominant, we are not affected with the action of the starrs.

And any object being removed from our eyes, though the impression it made in us remain; yet other objects more present succeeding, and working on us, the Imagination of the past is obscured, and made weak; as the voyce of a man is in the noyse of the day.
