3.24
A proposition about a complex stands in internal relation to the proposition about its constituent part. A complex can only be given by its description, and this will either be right or wrong. The proposition in which there is mention of a complex, if this does not exist, becomes not nonsense but simply false. That a propositional element signifies a complex can be seen from an indeterminateness in the propositions in which it occurs. We know that everything is not yet determined by this proposition. (The notation for generality contains a prototype.) The combination of the symbols of a complex in a simple symbol can be expressed by a definition.
