Moreno ruled out the supposition of how influential was
José Gaspar Rodríguez de Francia for the independence of Paraguay. He maintained that: "We can not identify the Paraguayan independence with Francia or attribute him the formation of our nationality because these affirmation, moreover than being contrary to the normal development of countries, are opposite to the documents and historical proves. The way of feeling and thinking of centuries does not change in a day with the effort of just one man."
Raúl Amaral affirms that Moreno’s historical work would have been of great diversity if he would not have been so focused on the problems in
Chaco, which consumes great part of his efforts. His work about the
Guaraní migration though, exposed in his investigations about the Chaco is of great value. In the defense of Paraguayan interests in the conflict with
Bolivia he pay special interest in the precise knowledge of the history, his obsessive dedication to this subject gave him the nickname of "Doctor de Límites" (Limits Doctor). Moreno was awarded with several decorations, Paraguayans and Bolivians. Moreno used to describe himself in a funny way: "I am republican, but I was a revolutionary fighter on October 18; I have several decorations without winning any battles, my name is Moreno (that means a person with dark skin) but I am white, I am sorry my friends, but I am no doctor." ==Last years==
