"So if the Knowledge of Corporeal Things were but a Secondary and Derivative Result from Sense, (though it cannot be conceived that the Passion of Sense should ray upon the Intellect, so as to beget a Secondary Passion there, any more than one Shadow should cast another) then Knowledge would be much a Weaker Perception of them than Sense it self is, and nothing but as it were the Secondary Reflection of an Image, or the Remote Cyclings and Undulations of the fluid Water, or the meer Echo of the Echo of an Original Voice: Or, Lastly, nothing but the Shadow of the Shadow of a Substance."
