Brazil's former president, Jair Bolsonaro (PSL), in his first remarks after his victory, in October 2018, delivered from his home via a live broadcast on social media, displayed a copy of the book alongside three others: the 1988 Brazilian Federal Constitution, the Bible, and Winston Churchill's The Second World War.

Following a change in leadership at Editora Record, where Rodrigo Lacerda took over as executive editor in January 2018, replacing , who had edited the book’s first editions, in 2021, the publisher decided not to renew a new wave of book releases by Olavo de Carvalho.

Critcal Journalist Reinaldo Azevedo, writing for Veja magazine, praised the book launch and noted that “He manages, like no other author in Brazil, whether you like him or not, to lend philosophical dignity to everyday life, without ever trivializing thought. This does not mean that he does not navigate, and his detractors do not criticize him any less for this; on the contrary, with mastery in the realms of theory and history.”

Luís Antônio Giron, writing for Época magazine, offered a mixed review of the book and wrote that “In a way, Olavo advocates a return to Latin, rote memorization, and the palmatoria to instill some culture in the horde of ignoramuses that populate Brazil. I actually agree with him. A little of all that would be a godsend for some idiots who think they’re the be-all and end-all. Except that the idiots haven’t read the book and aren’t reading this period either.”

Literary critic Rodrigo Gurgel praised Felipe Moura Brasil’s editorial work, noting that “The editor of this volume took care to include insightful and relevant notes that point to supplementary bibliography and provide illuminating excerpts from the author’s other texts.”
