The Commens Dictionary
Quote from ‘Letters to William James’
We must distinguish between the Immediate Object, - i.e., the Object as represented in the sign, - and the Real (no, because perhaps the Object is altogether fictive, I must choose a different term; therefore:), say rather the Dynamical Object, which, from the nature of things, the Sign cannot express, which it can only indicate and leave the interpreter to find out by collateral experience.
