721. Those reflections I could best compare with people's reflection on themselves. They are unaware that their hand or face is cold, or that their foot is pressed when they walk, or that they are speaking words when they speak, or that any other condition anywhere in their body exists, unless they reflect on it, or direct their thought toward it. There are besides many similar confirmatory examples, such as the fact that if we do not reflect upon the sounds of bells, or on the objects of sight around us, we are entirely unaware of having heard or seen them. 1748, 10 February.
