Quote from ‘Foundations of Mathematics [R]’
A sign in some sense corresponds to an object and also determines an interpretant sign, or is capable of doing so. Although it is not necessary that any person should originate the sign or that any person should interpret it, yet it will contribute to perspicuity to use language as if such were the case, and to speak of the utterer and the interpreter.
