"To explain this, we must consider that the first Image which an outward Object imprints on our Brain is very slight; it resembles a thin Vapour which dwindles into nothing, without leaving the least track after it. But if the same Object successively offers itself several times, the Image it occasions thereby increases and strengthens itself by degrees, till at last it acquires such a consistency (if I may so call it) as makes it subsist as long as the Machine itself. A Stock of Images having been thus acquired, they each have their respective little Cell or Lodge, where they go and hide."
— Arbuckle, James (d. 1742)
