Abstract

Kant seems to have been the first to notice that there is something peculiar about the difference between right and left, but he failed to say exactly what the peculiarity is. His clearest account of the matter is in his inaugural lecture (see Bibliography at the end of the paper): We cannot describe [in general terms] the distinction in a given space between things which lie towards one quarter, and things which are turned towards the opposite quarter. Thus if we take solids which are completely equal and similar but incongruent, such as the right and left hands . . . . although in every respect which admits of being stated in terms intelligible to the mind through a verbal description they can be substituted for one another, there is yet a diversity which makes it impossible for their boundaries to coincide
