ABSTRACT

Consider two statements about perception. The first is from Adam Smith’s Theory of Moral Sentiments:

As to the eye of the body, objects appear great or small, not so much according to their real dimensions, as according to the nearness or distance of their situation; so do they likewise to what may be called the natural eye of the mind: and we remedy the defects of both these organs pretty much in the same manner. In my present situation an immense landscape of lawns, and woods, and distant mountains, seems to do no more than cover the little window which I write by, and to be out of all proportion less than the chamber in which I am sitting. I can form a just comparison between those great objects and the little objects around me, in no other way, than by transporting myself, at least in fancy, to a different station, from whence I can survey both at nearly equal distances, and thereby form some judgement of their real proportions. Habit and experience have taught me to do this so easily and so readily, that I am scarce sensible that I do it.
