The first study analyses, from a legal perspective, the narrative of the short story "Ideias do Canário", published in 1899 by Joaquim Maria Machado de Assis. The text demonstrates, in an original and ironic way, the possibility of multiple and different perceptions of the same reality, with the various shades of truth varying according to the subjective understanding of those who describe them. The second article deals with the Theory of Criminal and Criminal Procedure Guarantees developed by Professor Luigi Ferrajoli, which has often been severely criticised by supporters of the "Criminal Law of the Enemy", "Criminal Abolitionists" and even human rights defenders. The third and final section deals with reading as one of the main tools for individuals to build their knowledge and learn to exercise citizenship, hence the importance of awakening the pleasure of reading in children at the beginning of the knowledge process. It also shows that this work must be done together, with parents, children and teachers, each of whom has a fundamental role to play in building this new reader and improving their learning.
