This chapter deals with the link between language and epistemology of time, according with the paper issued in this session. The arise of natural science, in Early Modern Age, makes possible the constitution of an epistemic paradigm which connects himself to the definition of human nature, and allows to research objective rules for the human history and human language. The Early Twentieth century, breaks (or tries to break) this standard, as is possible to see in the essays proposed in this part of the book.
