A sign is a species under the genus representamen, the definition of which says nothing about a mind. A representamen is an object A, in such a triadic relation to an object, B, for an object C (the italicized prepositions merely indicating a difference between the relations) that it is fit to determine, C, to being in a similar triadic relation to A, and thereby (owing to the peculiar nature of this type of relation,) necessarily to B, for some third object, C’, determined in like manner, and so on ad infinitum.
