In propositions thoughts can be so expressed that to the objects of the thoughts
correspond the elements of the propositional sign.
3.201 These elements I call "simple signs" and the proposition "completely" analysed.
3.202 The simple signs employed in propositions are called names.
3.203 The name means the object. The object is its meaning.
("A" is the same sign as "A".)
