The Commens Dictionary
Quote from ‘Letters to William James’
As to the Object, that may mean the Object as cognized in the Sign and therefore an Idea, or it may be the Object as it is regardless of any particular aspect of it, the Object in such relations as unlimited and final study would show it to be. The former I call the Immediate Object, the latter the Dynamical Object. For the latter is the Object that Dynamical Science (or what at this day would be called “Objective” science) can investigate.
