"We are not enough to disagree so much!" It is with this emblematic phrase that the author ends this book. We will follow a little of this reflective journey that Marcelo Bafica Coelho has developed, based on the New Rhetoric framework, to examine some of the argumentative practices characteristic of the context of graduate studies in Education in Brazil. A journey that includes philosophical and historical considerations, always well connected. The text is light and fluent. An invitation, therefore, to be attentive to the power of these words.
