Quote from ‘On the Logical Nature of the Proposition’

A sign is an object capable of determining in a mind a cognition of an object, called the object of the sign. A sign is a species under the genus representamen. 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 dyadic relation of A to B, and that of A to C) that A is fit to create C by the determination of something, so that C shall be in the same triadic relation to A, and thereby (such is the peculiar nature of this triadic relation) to B, for some third object, C’, determinable in the same manner, and so on ad infinitum.
