“For the limits to which our thoughts are confind, are small in respect of the vast extent of Nature itself; some parts of it are too large to be comprehended and some too little to be percieved. And from thence it must follow, that not having a full sensation of the Object, we must be very lame and imperfect in our conceptions about it, and in all the propositions which we build upon it; hence we often take the shadow of things for the subftance, small appearances for good similitudes, similitudes for definitions; and even many of those which we think to be the most solid definitions, are rather expressions of our own misguided apprehensions then of the true nature of the things themelves.”
