hreshold of the existence of signs. Yet even here, things are not so simple, and the meaning of a term like "the existence of signs" requires elu-cidation. What does one mean when one say!, that there are signs, and that it is enough for there to be signs for there to be a statement? What spe-cial status should be given to that verb to be?
The existence of the statement proves that signs exist. However, they are not one in the same: first, one must determine what he or she means by "signs;" then, he or she must determine exactly the connotation of "to be" for something "to be a statement" or "to be a sign," because this distinction can change the meaning one assigns to what a statement or a sign is.
