Definition of "representamen"

The Leibnitzio-Wolfians distinguish three acts in the process of representative cognition: — 1° the act of representing a (mediate) object to the mind; 2° the representation, or, to speak more properly, representamen, itself as an (immediate or vicarious) object exhibited to the mind; 3° the act by which the mind is conscious, immediately of the representative object, and, through it, mediately of the remote object represented.

1861, Sir William Hamilton, The Metaphysics of Sir William Hamilton, page 318

A sign, or representamen, is something which stands to somebody for something in some respect or capacity.
