Chapter 2 redefines the three basic concepts of any rhetoric: ethos, logos, and pathos. It relates these elements to the questioning process by which they are rhetorically linked. Special attention is given to logos as a way of answering and expressing questions. This leads to the development of a radically new view of language and the principles of thought. The passage of a propositionalist view of language and reason, indifferent to questioning, to a problematological one, based on questioning is studied through examples of sentences. This leads to an integrative view, in which texts are also seen as answers to questions taken up (partially, i.e. as points of view) by the audience or the reader. The chapter ends with a reformulation of the basic principles of thought (identity, sufficient reason, and non-contradiction) as the three principles necessary to deal with questions, answers, and their relationship.
